(1) Special design structural design measures of explosion-proof body structure in order to prevent combustible dust precipitator internal components fouling, all beams, partition boards should be set dust plate, and dust-proof plate slope should be less than 70 degrees . Hopper slip angle is greater than 70 degrees, in order to prevent the two walls bucket angle is too small to fouling, two adjacent side panels should slide on the solder plate, to eliminate dust deposits, taking into account that the operation is not normal humidity and dust condensation occurs when a large block of cold ash bucket, ash bucket design, the hopper wall on the high-temperature steam pipe insulation or increase dust tubular electric heater. To prevent gray mantle material, you need to set each hopper or bin vibrator arms air guns. (2) anti-static dust bag in the interior, due to the high concentration of dust with each other during flow friction, dust cloth and rub against each other but also can produce static electricity, static electricity accumulated rally sparks cause a fire. For pulse cleaning method, with polyester needle felt filter bag, to eliminate static electricity is easy to produce polyester needle felt inadequate, spinning into the fabric bag conductive metal wire or carbon fiber, the installation of the bag, the bag through the steel skeleton and a porous plate is connected to ground through the housing connected to the workshop network. For reverse air cleaning filter bag, we have developed a variety of anti-static MP922. Effect is very good. (3) set the security hole (valve) is limited to the explosion inside the filter bag and does not extend to other areas, setting up security holes and essential firefighting equipment, real important. Set security hole is not intended to allow security holes to prevent an explosion, but use it to limit the explosive range and reducing the number of explosions. Most of handling explosive dust precipitator is operated at conditions of setting up security holes. Because of this, the security hole should be designed to ensure that in case of explosion, can effectively play a role;
