Baghouse dust collector

The working principle of the dust collector is as follows:

The dust collector is mainly composed of the upper housing, middle housing, ash hopper, air inlet distribution pipe, support filter bags, and spray blowing device, ash discharge unit, etc. The dusty gas enters the ash hopper of each compartment through the air inlet distribution pipe of the dust collector and is separated under the guidance of the ash hopper guiding device, with large particles of dust falling directly into the ash hopper, while finer dust is evenly distributed into the middle housing and adsorbed on the outer surface of the filter bags. The clean gas passes through the filter bags into the upper housing and is then discharged into the atmosphere through various offline valves and exhaust pipes. As the filtration process continues, the dust accumulates on the filter bags. When the equipment resistance reaches the specified resistance value (usually set at 1500Pa), the offline valve of one compartment is automatically closed by the ash cleaning control device according to the differential pressure set value or ash cleaning time set value. The electric control pulse valve is then opened according to the set program, and the stop wind spray is performed. The compressed air is used to instantaneously spray, increasing the pressure inside the filter bags, causing the dust on the filter bags to be shaken off (even sticky fine dust can be cleaned thoroughly) into the ash hopper, and then discharged by the ash discharge mechanism.

Principle of Dust Collector Operation:

Dust-laden gas enters the filter chamber through an open-bottomed flange. Coarser particles fall directly into the ash storage. The dust-laden gas is then filtered through the filter bags, with dust particles being retained on the bag surface. The clean air exits through the bag mouth into the clean air chamber, where it is exhausted into the atmosphere by a fan. As the dust on the surface of the filter bags accumulates, a programmable controller starts up, sequentially opening pulse valves. Compressed air is then blown through the nozzles to clean the bags, causing them to suddenly expand. Under the effect of the reverse airflow, the dust adhered to the bag surface quickly detaches and falls into the ash storage, from where it is discharged through the ash discharge valve.
