The term Wet Scrubber Cyclone Bag Filter describes a variety of devices that remove pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants.
A venturi scrubber is designed to effectively use the energy from the inlet gas stream to atomize the liquid being used to scrub the gas stream. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.
Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquids, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids.
Multi-cyclone is filtering equipment that brings together in one single body, numerous smaller cyclones, fitted parallel, in order to the reduce height and volume that would otherwise be needed by a cyclone with the same flow.The multi-cyclone houses in its interior highly efficient cyclones, designed to obtain greater centrifugal strength over the particles transported in the air, than those obtained by cyclones
Pulse jet bag filter is one type of Baghouse dust collectors using large array of filter bags for air filtering and high velocity pulsed air passed in reverse direction to airflow onto bags for cleaning. The other two types of baghouse dust collectors are shaker type bag filters and reverse air baghouse dustcollectors . Of all the three types of baghouse dustcollectors, pulse jet is the most effective and economical type because of high air to cloth ratio, smaller size in comparison to other two of same capacity, continuous duty because of online cleaning advantages.
Bagfilter is one of the most efficient and cost effective dust collector models. In baghouse filter, the dust filled air stream passes through fabric bags that filter the dust particles. Bags are made of different material such as woven or felted cotton, synthetic, or glass-fiber. The bags are cleaned manually by giving a manual shaker mechanism.
In a reverse air baghouse, the dirty air flows from the inside-to-outside, so that the dust collects on the inside of the filter bag. The filter bags are tubular, open at the bottom and connected to a tubesheet. They are supported from the top through a spring or J-bolt suspension system. The gas flow is reversed to initiate filter bag cleaning. Anti-collapse rings are sewn onto the outside of the bags at 3 to 4 foot intervals to prevent total collapse of the bags during the reverse air cleaning. Filter bags are cleaned one compartment at a time in the off-line mode.
