Product overview
LCM long bag pulse filter is a new type, high efficiency bag type dust collector is developed based on the conventional short pulse dust collector bag. It combines the advantages of sectional reverse blow and pulse cleaning technology, adopting off-line automatic control of the cleaning mechanism, give full play to brute force of compressed air blowing ash effect; long bag design, reduce steel consumption, reducing the occupied area; according to the application needs can be matched with various media, to meet the needs of high dust. Has been widely used in metallurgy, machinery and other industries of the dusty gas purification and recovery of materials.
Filter process:
Gas dust hopper into each of the filter units assigned by the middle air inlet channel, coarse dust particles in inertia and gravity directly into ash hopper, fine dust particles with the flow turning upward into the filter chamber, filter bag dust on the surface of the cake, dust deposition on the surface of the filter bag, the filtered gases in the upper box body is composed of filter bag, and convergence to the net gas manifold, exhaust duct, the system fan is discharged into the atmosphere.
Cleaning conditions:
With the accumulation of dust on the surface of the filter bag, filter resistance will increase, then need to start cleaning process. LCM dust collector adopting off-line lab wind stopped cleaning mechanism. Cleaning process begins, first close the net gas outlet air duct of a filtering unit, the unit in the bag without airflow through the state. Then open the pulse valve, so that the high speed flow of compressed air sprayed into the bag, and the clean air chamber air net formed two wind suction filter bag filter bag, sharp deformation vibration, shake off the dust. The settlement after a period of time, open the unit net gas exports, restore the filtering condition, and a filter unit into the ash, until all units are implementing a pulse cleaning, complete with a dust precipitator.
Dust control:
Filter adopts PLC control system, according to the different treatment process, can choose the pressure difference control and timing control reverse blowing. Differential pressure control mechanism, in accordance with the dust collector resistance values of opening and closing back blowing process. When the resistance of the dust catcher dust boot reaches a preset value (1200~1500Pa, ), a startup control signal cycle duster blow, go round and begin again one unit to execute " ash -- Settlement -- filtering " cycle, reduce the resistance of the dust remover to resistance until the limit set ( usually 1000Pa ). Differential pressure control mechanism can make the resistance of the dust remover is controlled in a certain range, precipitator maintains the best removal efficiency and the lowest energy consumption.
Timing control is based on the experience of numerical implementation, arrange the timing counter blowing, generally used for system operation is relatively stable treatment.
Dust treatment:
Dust collected into ash hopper, the chain conveyor, hoist equipment transported to the ash storage silo, regular.
