The gas after the blast furnace bag filter is initially separated (coarse and clean), enters the box through the lower air inlet of the box of the dust collector. The larger dust particles will naturally fall into the ash bucket by their own weight, and the smaller particles will be dispersed in the filter. The space between the filter bags in the room is blocked on the surface of the filter bag, and the filtered clean gas is sent to the user by the pipe network. With the progress of the filtering conditions, the dust filter is attached to the surface of the bag, and the resistance of the filter bag gradually increases. When the resistance value of the filter bag reaches the upper limit, the net gas backflush valve can be automatically opened by the system control to send the net gas to the static The pressure box is used to blow back the filter bag, so that the filter bag changes from the suction state to the expanded state, so that the dust adsorbed on the outer surface of the filter bag is shaken into the ash hopper in the lower part of the box.
Determining the air volume of the dust removal system is a complex and critical step in the dust removal system and a key factor affecting the dust removal effect. Low air volume will result in poor capture effect, yellow smoke will be emitted from the roof of the plant, environmental protection requirements will not be met, and poor labor and sanitary conditions in the workshop; high air volume will increase project cost and operating costs, causing unnecessary waste.
