First, the dust consists of: cartridge filter from the inlet pipe, exhaust pipe, tank, hopper, cleaning devices, cartridges and electric control device component. Cartridge filter cartridge in the layout is very important, the cartridge can be disposed vertically in the housing board flower, the flower can be disposed inclined plate, bolted, and the rubber pad, lower part of the filter chamber, on the part of net gas chamber cartridge in addition to bolt, but more convenient method is the automatic locking device and a rubber plant, these two methods are very easy to install and maintain. Second, the principle: dusty gas enters cartridge filter, due to a sudden end airflow and air distribution plate to expand the role of a part of the gas stream coarse dust particles in the gravitational and inertial force of the settlement to the hopper; fine grain size, density, small dust particles into the filter chamber, through Brownian diffusion and fiber interception combined effect of the dust deposited on the surface of the filter cartridge, purified gas into clean gas chamber from the outlet by the fan discharge. Cartridge filter cartridge with a surface area of ??the resistance becomes large ash increases, when the resistance reaches a certain set value, PLC program control pulse valves open and close, when the pulse valve is open, the compressed air through the air bag expansion of the venturi tube, into the cartridge evenly inside the cartridge pressure formed inside the moment, a huge vibration, the dust deposited on the filter off, fall into the hopper, the collected dust through the dust discharge valve is discharged to the ash container. Third, the performance characteristics: (1) the use of advanced heavy flow layout and cartridge loading ramp structure, and thus dust in the work process synchronization cleaning effect; (2) purification efficiency for submicron dust over there purification efficiency of more than 99.9%, the device operates with low resistance, the effective energy saving dust removal system; (3) Dust inlet of dust and gas plate, a buffer effect and wear-resistant, high-speed impact is not directly cartridge so that dust, which can be extended cartridge life; (4) Cartridge 15 ° tilt drawer-mounted, removable cartridge can be more convenient, but the body does not set the filter transmission parts, so maintenance work to a minimum. For general dust, long-term use does not require replacement cartridge, eliminating the need to frequently wash frequently used baghouse filter bag tedious work, and save a lot of maintenance costs; (5) modular combinations, the size can be freely selected You can expand the existing portfolio, increasing dust removal unit, without the need to make too many changes to the original equipment;
