Pulverized coal pulverized dust filter, also known as pulverized coal collector. Mainly used to treat flue gas dust containing coal, carbon, flour and other flammable and explosive. Mainly used: coal preparation, coal transportation, pulverized coal injection and other working conditions. Pulverized dust equipped with an external insulation, pressure relief valve. Bag choose three defenses (water and oil proof anti-static) bag. To ensure the dust collector hopper not bonded coal dust, dust to ensure the recovery of coal dust falls into the hopper. Precipitator ash hopper of an inverted cone, the overall stiffness, angle of repose hopper ≥70 °, after the rotary valve hopper bottom ash screw conveyor configuration, the coal dust to the dust collection bin for recycling. To ensure that the inner wall of flat and smooth in the production process, the outer wall of the hopper install the warehouse wall rapper. Design techniques for pulverized coal explosion of 1, blockades and cinder mechanism design to prevent dust generation within the hopper wall and bypass sticky phenomenon, slip angle is greater than 70 ° hopper to prevent gray cloak material, each hopper need to set the rapping mechanism. 2, anti-condensation precipitator design means whole design of thermal insulation, the vacuum port electric valve dust removal system, screw conveyor, rotary ash valve key components, dust, etc. hatch has electric heating, insulation, etc. freezing measures, on-site implementation insulation construction, insulation quality. 3, antistatic laminating media, and the precipitator flower plate, then connected to ground, can effectively prevent the accumulation of static electricity, to prevent static electricity and sparks explode between the flanges. 4, explosion-proof door with modular door bursting disc and gravity, can guarantee the venting safety and reducing air leakage rate ≤3%, improve operational efficiency dust collector. 5, coal dust internal set of guiding plate, to prevent fouling, in addition to strengthening the distance between the ribs and the bag must not be less than the distance between the filter bag.
