Desiccants

So often when the word “desiccant” is used, people automatically think of the three main types of desiccants: Indicating Silica Gel, Molecular Sieve, and Clay desiccant. Those who have heard of other desiccants, like Calcium Oxide, Montmorillonite Clay and Calcium Sulfide, may or may not have a clear understanding of those desiccant types. Realizing how important proper discernment is where the use of desiccants is concerned

Montmorillonite Clay

Montmorillonite clay is a naturally occurring adsorbent created by the controlled drying of magnesium aluminum silicate of the sub-bentonite type. This clay will successfully regenerate for repeated use at very low temperatures without substantial deterioration or swelling. However, this property causes clay to give up moisture readily back into the container as temperatures rise.
Clay is a good basic desiccant that works satisfactorily below 120°F (approximately 50°C). Above 120° F, there is a possibility that the clay will give up moisture rather than pulling it in, so anticipated storage and transportation conditions should be considered. The upside to clay is that it is normally the least expensive desiccant per pound.
Clay is highly effective within normal temperature and relative humidity ranges. Its appearance is that of small gray pellets. Care should be taken to be sure that any low level impurities in the clay are not incompatible with the packaged product.

Silica Gel

Silica gel is silicon dioxide (SiO2). It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a desiccant, it has an average pore size of 24 angstroms and has a strong affinity for moisture molecules. The silica gel will pull in moisture at temperatures up to 220°F (105°C). As temperature goes above 100°F, the rate of moisture pickup will slow down but the silica gel will still work.
Silica gel performs best at room temperatures (70° to 90°F) and high humidity (60 to 90% RH) and will drop the relative humidity in a container down to around 40% RH. In the United States, silica gel is commonly used in food and pharmaceutical applications as only silica gel has been approved by the FDA for direct contact with these items.

As with clay, silica gel, with its wide range of pore sizes, has the capability of adsorbing compounds other than water. The relative order of adsorbability is: water, ammonia, alcohols, aromatics, diolefins, olefins and paraffins. When the potential for multicomponent adsorption is present, expect the more strongly adsorbed compounds, such as water, to displace the more weakly held ones.

Electrostatic filters.


Electrostatic filters do NOT use any physical filter material such as paper, cloth,  fibre etc., to capture fine particles, but uses a high voltage electrostatic charge between a series of aluminium plates instead, to first charge floating particles as small as 0.01 micron  (1 micron is 1/25,400th of an inch ). These positively charged particles are subsequently collected on negatively charged aluminium plates, and the clean air , devoid of particles is sent out of the filter . The efficiency is between 95% to 100% for various particulates. 
The main advantages of Electrostatic Filters are :
1.The Filters are permanant and are for the lifetime of the equipment .They can be cleaned as many times as required unlike standard filters which have to be replaced after a fixed time period, involving a replacement cost .
2.The filters can capture particles as small as 0.01 micron as compared to just 5 microns in standard filters. Thus Fumes such as cigarette smoke, welding fumes, etc can be captured, which standard filters cannot do .
3.The power consumption is upto 40% lower than when using standard filters.
4.The filters can be used for recovery of oil and coolant fumes in CNC machines, and the recovered oil or coolant may be reused giving considerable savings .
5.Pressure drop across these filters is very low .

Conventional filtration techniques just cannot compete with electrostatic filtration as highlighted through the following table.

How it Works:
A two-stage electronic precipitator is constructed in two sections - a charging (or ionizing) section, and a collecting section. The charging section consists of a series of fine wires suspended between metal plates, tubes, air foils or other shapes; the collecting section is a series of parallel flat metal plates .

In single-stage precipitators, both charging and collecting are accomplished in one section. Since the end result is much the same as the charging section of a two-stage EAF (Electronic Air Filters), an explanation of the two-stage EAF is sufficient for both types.
Note:-In practice a small amount of collection actually occurs in the charging section of the two-stage EF, but most particles are carried through the charging section by the air stream to the collecting section where they are attracted to the charged collecting plates. Keep in mind that the airborne particles in either case are first given an electric charge. Then they are collected on plates which have an opposite charge in relation to the particles. (Like charges repel, unlike charges attract. )
To fully understand the operation of the Electronic Air Filter, it is necessary to review, briefly, the molecular structure of matter. A molecule is the smallest portion of any substance that can exist and still retain the chemical characteristics of the substance. Each molecule contains one or more atoms. An atom contains a nucleus, with a positive electrical charge and orbiting electrons, each with a negative electrical charge. The negative charges on all electrons are equal. In an electrically neutral molecule, enough electrons are present to equal the sum of the positive charges on the nucleus. If one or more of the electrons is knocked out of the molecule, the molecule is left with a surplus of positive charge and is then called a positive Ion. A positive Ion in an electrostatic field will be propelled toward the negative side of the field, while the freed electron is propelled towards the positive side of the field. The propelling force is proportional to the field intensity. A negative ion can be formed if a foreign electron is impacted into a gas molecule or into a particle.
Free electrons, those not attached to atoms, can be created almost everywhere. Within the electrostatic field of an EAF, free electrons accelerate rapidly toward the positively charged ionizing wires. The rate of acceleration becomes greater as they pass through the increasingly higher field intensity while approaching the wire. On the way to the wire, these accelerated free electrons strike air molecules and knock other electrons out of them. These liberated electrons are then free to strike other molecules. In this way a vast number of positive ions (molecules with surplus positive electrical charge) are created and move rapidly toward the grounded plates.
A pale bluish glow appears about the fine wires of an operating EAF. This is a visible indication of a corona discharge. The incoming particles receive their charge from the flow or electrical current (ions) from this discharge to the ground plates of the ionizer. The corona glow is most readily seen on the upstream side of the EAF when it is newly cleaned, operating properly and in complete darkness. Then again, you may not see a glow at all, but this does not mean that the corona discharge is not taking place.
When a continuous d-c voltage is applied to a fine wire suspended between grounded metal plates, a "non-uniform" electrostatic field is formed in the inter electrode space (area on both sides of the wire between the grounded plates). The field is non-uniform because it is very strong near the wire, but decreases rapidly as the distance between the plates and the wire increase. Increasing the voltage applied to the wire increases the field strength and its "distance gradation" - until, depending on the relative sizes, the shape of the wire, the distance between wire and plates, and the applied voltage - "corona-start" conditions are satisfied and the gas molecules (air) near the wire are forced to undergo an electrical change.
The disruption of the atoms in the ionization process cause energy to be radiated. Some of this energy is of the wave lengths of visible light and under some conditions produces a bluish light around the ionizing wire, giving a visible indication of corona discharge.
Ions Hitch a Ride
A dirt particle entering the deluge of gas ions is much like an airplane flying into a rain storm. "Getting wet" is inevitable. As the airborne particles pass through the electrostatic field, the ions "bombard" or collide with and attach to it. The particles then exhibit the electrical charge of the ion "hitch hikers" - the strength of the charge depends upon the number of "hitch hikers" picked up. Therefore, the larger the particles, the greater the electrical charge. This complex charging process takes place in about one-hundredth of a second. The great majority of particles charged in this way have the same charge as the corona discharge wire and are collected on the negative plates in the collector section
Charged Particles Collect on Plates 
Let’s move our attention along with the charged particles into the collecting section and see what happens there. (Incidentally, the dirt collection that occurs in the charging section or in a single stage electrostatic precipitator is very much the same as what follows). 
Recall that the collecting section is comprised of a series of flat metal plates set parallel to the air flow through the cleaner. Their spacing varies somewhat from air cleaner to air cleaner, but is usually in the neighborhood of a quater-inch apart. To make the collector work, a high voltage d-c source (+) is applied to each alternate plate and the intervening plates are grounded so there is a high voltage difference between the plates.
We can examine the collecting process by viewing what occurs on one set of two adjacent collector plates. (The following statements apply equally well to the whole series of plates). A uniform electric field of force is produced between the two plates when a voltage is applied to them. This force field cause a uniform distribution of electrons (negative charge) on the surface of one plate, and an equal and uniformly distributed deficiency of electrons (positive charge) on the other. The voltage gradation is uniform throughout this field, except at its edges and near sharp corners of the plates.
A single positively-charged particle entering this field is acted upon by a force equaling the sum of all attracting and repelling forces. These forces are due to the charge on the particle interacting with the field produced by the plates. These forces accelerate the positively-charged particles toward the negatively-charged plate. In the same manner, a negatively charged particles is forced towards the positive plates. The amount of force acting on the particle depends on the particle’s charge, the voltage applied to the collecting plates and the space between the plates.  
The uniformity of the field causes a particle to be acted upon by an equal force regardless of whether the particle is close to a negative plate, to a positive plate, or somewhere between. If no other force is acting on the particle, it moves with a constant acceleration (constant velocity increase) toward the negative plate.
Other forces also act on this little particle. These forces are the resistance of the air stream, the repelling and attracting forces between it and other particles, gravity and inertia. These forces affect the movement of the particles toward the collecting plates, causing the particle to follow an approximate diagonal path to the collector plate. (From the preceding statements you can see that the velocity is a very important factor in air cleaner performance).
The particles that are collected and are in physical contact with the charged collector plates lose their "opposite charge" and take on the charge of the respective collector plates. They remain attached to the collector plates because of molecular adhesion and due to cohesion to other particles already collected. Sometimes a prepared adhesive is applied to the collector plates in an attempt to increase their holding power. Such preparations may also make the plates easier to wash. Generally these preparations are unnecessary. Heavy loading of fine dry particles is one of the few situations where an adhesive may be useful. Most dirt contains enough oil, tar and residue that is naturally sticky so that washing the dirt away is of more concern than the chance of it blowing off while the EAF is in operation. Carefully washing the dirty cell at the correct intervals is the most effective means of effecting efficiency.

 

The extractor arm is a device which allows the user to position a suction hood to capture fumes or dust close the generation spot with complete ease and flexibilty





The extractor arm is a device which allows the user to position a suction hood to capture fumes or dust close the generation spot with complete ease and flexibilty. The extractor arm consists of 2 ducts made of aluminium connected by PVC hose and mounted on interconnecting support rods with friction -loaded pivots.A suction hood is attached to one end.The other end is attached to a rotating hollow cylinder.The suctionhood, ducts, hose and rotating cylinder form a passage for the fumes or dust. The entire arm is self balancing and articulated at 3 points. This allows the suctionhood to be positioned by hand at any point with a reach of 2 meters(or 4 meters) to & fro and 2 meters(or 4 meters) up & down with a complete ease & flexiblity with minimum force. The extractor arm can be fitted to most of our Fumekiller models & Dustbag models. The arm can also be fitted to overhead ducting to provide suction points close to the floor level for the capture of fumes or dust from pollution generation spots.

The extractor arm consists of elements of aluminium ducts joined by flexible hose , articulated at 3 fulcrum points . One end of the arm is fitted with a suction hood and the other end is fitted with a swivel fixture. The arm is self balanced using friction pads and a telescopic gas tube. The arm can be swiveled by hand through about 270 degrees and can be positioned easily within a nominal distance specified for each arm. With the Extractor arm , fitted to the Fumekiller or Dust Bag the suction hood of the arm is to be positioned close to the fumes/dust generation spot. The fumes/dust will be sucked through the suction hood and will reach the Fumekiller or DustBag for filtration.

Dust and Fumes control using Electrostatic Filtration.




Dust and Fumes control using Electrostatic Filtration 

These Filter Modules are high-efficiency, two stage electrostatic filters, designed, developed and manufactured by Powertech Pollution Controls Pvt. Ltd., Bangalore.
Feature


A safer, healthier working environment where hazardous fumes and airborne contaminants are removed.
  • No replacement of the electrostatic modules for the lifetime of the equipment.
  • Low running cost. High filter efficiency, low pressure drop.
  • Can be incorporated into existing air flow systems with minimal effect on the overall pressure or air flow capacity of the system.
ApplicationsThese modular filters are used for custom built applications & can be added module by module to suit various air flow rates. These modules are used as primary filters for Class 100,000 Clean Rooms & as Prefilters for higher Class levels of Clean Rooms. When used as pre-filters for higher class levels, they can increase the life of the terminal filters. The total pressure drop as compared to conventional pre-filters is negligible. These filters can be used in a centralised system for removal of fumes, smoke, oil mist, coolant mist, dust and fine powders from many in - plant industrial processes which generate pollutants rendering the shop floor unhealthy.

How It Works 

Each filters module can handle an air flow rate as specified. The required quantity of modules are placed in an MS painted enclosure. The air inlet side is placed in the air stream using a suitable adaptor ducting. The power pack feeding the electrostatic voltages to the Modules is separately mounted in a control panel near the MS enclosure with the electrical connections made through conduits. Prefilters and post filters are placed before and after the electrostatic filter modules. Dust and fine particulates are sucked into the filters modules with the air stream. These first enter the prefilters which prevent large particles entering the Modules. The fine particles then enter the Modules where, between a series of parallel aluminium plates, they receive a high positive charge, The positively charged particles then pass through another series of negatively charged aluminium plates. Here, the particles are attracted to the oppositely charged plated and stick to them like iron filings to a magnet, but with a difference - the particles remain adhered to the plates even when the electrostatic filter is powered off. The clean air, devoid of particles, escapes through the after filters. The post filters help in distribution of the air flow through the electrostatic filter modules.

Dust bag, dust collectors ,are fitted with Nonwoven polyester fabric capable of capturing dust particles as small as 10 micron




Dust bag, dust collectors ,are fitted with Nonwoven polyester fabric capable of capturing dust particles as small as 10 microns and are designed, developed and manufactured by Powertech Pollution Controls Pvt. Ltd., Bangalore.
Feature
Removes harardous dust. 
Fitted with manual de-dusting arrangement for in-situ dusting of filter bags.
High filter efficiency of 98%. 
Can be fitted with anti-static, or fireretardant filter fabric, if required.
Separate dust collection bin for easy disposal of dust.
Applications

Dust bag, dust Collectors can be used to capture dry or mildly wet particles from tool & cutter grinders, cast iron machining, graphite / carbon machining, surface grinders, drilling, milling, deburring, polishing,
mixing, etc.

How It works 
The DustBag dust Filter can be used in 2 ways. It can be used for pedestral grinders or similar applications where the grinding wheel can be enclosed upto 70% with a specially designed mild steel suction hood. The hood has an outlet to which a PVC flexihose is connected. The other end of the flexihose is connected to the inlet of the DustBag. It can be used for surface grinders, CNC machining, or similar application where the wheel or machining tool cannot be enclosed. In this case a rectangular suction hood can be placed in the stream of the dust particles near the grinding wheel edge or machining tool edge. During the dust generation process, dust particles are drawn into the DustBag from the suction hood. The larger dust particles in the airstream, after entering the DustBag fall to the bottom collection tank immediately. The finer dust particles reach the filter bag and are trapped there. The clean air leaves the DustBag from the top. The filter bags can be de-dusted using the lever at the side which when shaken vibrates the bags which are spring-mounted. It is not neccesary to remove the bags for cleaning.

DustKiller can be used for controlling dust and fine particles in any closed room.






DustKiller - Dust filtration system, is a high-efficiency, two-stage electrostatic precipitator, designed, developed and manufactured   with suction vom by Powertech Pollution Controls Pvt. Ltd, Bangalore, India, with built-in fan blower used for control of atmospheric dust in closed rooms.
Feature
Achieves a high level of dust control, with removal of around 80% of atmospheric dust levels existing in the enclosed area.
  • Captures fine particulates before they settle down on precision equipment.
  • High filter efficiency.
  • Low electrical running cost.
  • No replacement of electrostatic module.
  • High reliability and easy maintainance.
  • Complete factory support from engineering professionals, based on years of expertise in industrial pollution.
Usage

DustKiller can be used for controlling dust and fine particles in any closed room, preferably but not necessarily fitted with window/split type airconditioners - electronic labs, mechanical precision assembly areas, standards room, metrology labs, pharmaceuticals,bio-tech'labsetc. or wherever dust control is a necessity DustKiller can be quickly installed without major changes in the existing area.

How It Works 

Dust and fine particulate matter are sucked in with the air stream by the centrifugal blower (1) through the inlets (2) on top. These enter the prefilters (3) where large particles are removed. The remaining fine particles then enter the electrostatic module(4) where, between a series of parallel aluminium plates, they receive a high +ve charge. These positively charged particles then pass through another series of aluminium plates which are negatively charged. Here, the particles are attracted to the oppositely charged aluminium plates and stick to them just like iron filings are attracted to a magnet, but, with one difference - the particles remain adhered to the plates even when the electrostatic filter is switched off. The air, now devoid of particles, escapes through the outlets (5) as clean air. The postfilters (6) help in even distribution of air flow through the electrostatic module.
