The structural components of the 240 bag bag dust collector used in Shijiazhuang Foundry are as follows:
(1) The dust collector consists of an upper box, a middle box, an ash hopper, a bracket, a filter bag component, a reverse blowing cleaning mechanism, and an ash discharge valve.
(2) Dust collection and filtration system: mainly composed of filter bags, bag cages, flower board components, ash hoppers, and tangential air intake system.
.(3) Ash cleaning and unloading system: high-pressure fan, rotary blowback pipe, reduction motor.
.(4) Electrical control system: Automated control system.
Basic principle of bag filter used in Shijiazhuang Foundry:
Dust containing gas enters the upper space of the filter chamber in a tangential direction. Under the centrifugal force of large particles and condensed dust particles, small particles in the ash hopper spin down along the cylinder wall and disperse in the gaps between the bags in the filter chamber, thus being blocked by the bags. Purified air passes through the bag wall and is collected in the clean room through the filter bag guide on the flower plate, and is sucked in by the ventilation fan and discharged into the atmosphere.
The bag filter used in Shijiazhuang Foundry adopts the design concept of high air volume and low air speed. The actual filtration wind speed of the dust collector is selected as 1.4m/min. Before the equipment leaves the factory, the main parts of the injection system are pre assembled, and a secondary airflow distribution method is adopted to allow the dust containing gas to enter the filtration area through the guide pipe and inlet air distribution system. The uniform and smooth inlet air of the unit is used to improve the utilization rate of the filtration area and the service life of the filter material.
