Dust Extraction System:
Dry air dust extraction system captures airborne dust from its source. The captured dust is then transported to a dust collector (usually bag filter), which cleans the dust-laden air. Bag Filters are one of the most efficient and cost effective types of dust collectors available and can achieve a collection efficiency of more than 99% for very fine particles.
We provide pulse-jet type bag houses where individual bags are supported by a metal cage which is fastened on to the bag holding plate. Dirty gas flows from outside to inside the bag while the metal cage prevents the bag from collapsing. Bags are cleaned by a short burst of compressed air injected through a common manifold. This compressed air burst while travelling through the entire length of the bag causes the bag surface to flex, which breaks the dust cake and the dislodged dust falls into a storage hopper below.
Cyclonic separation is a method of removing particulates from an air, gas or water stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids.
A high speed rotating (air) flow is established within a cylindrical or conical container called a cyclone. Air flows in a spiral pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger (denser) particles in the rotating stream have too much inertia to follow the tight curve of the stream and strike the outside wall, falling then to the bottom of the cyclone where they can be removed. In a conical system, as the rotating flow moves towards the narrow end of the cyclone the rotational radius of the stream is reduced, separating smaller and smaller particles.
We have been providing Dust Extraction systems incorporating centrifugal fan, bag filter unit, dry/wet cyclone, rotary air lock, screw conveyor, MS ducting, motorized dampers etc. as per client's requirement. Our design engineers are well equipped to custom design a dust extraction system if provided with relevant input data and drawings. We have always successfully met the emission level of dust stipulated by the Pollution Control Board.
