The working principle of the dust collector is as follows: the dust-containing gas enters the filter chamber from the lower open flange, and the coarser particles directly fall into the ash bin. The dust-containing gas is filtered through the filter bag, and the dust is retained on the bag table, and the net gas is passed through the bag mouth. The clean air chamber is discharged into the atmosphere by a fan. When the dust on the surface of the filter bag increases continuously, the program controller starts to work, and the pulse valve is opened one by one, so that the compressed air is sprayed and cleaned through the nozzle, so that the filter bag suddenly expands, and under the action of the reverse air flow, the bag table is given. The dust quickly leaves the filter bag and falls into the ash bin, and the dust is discharged by the ash discharge valve.
When the membrane dust collector works normally, under the action of the system fan, the dust-containing gas is sucked into the intake manifold, uniformly distributed to each inlet chamber through each intake branch pipe, and then poured into the filter bag, and a large amount of dust is trapped on the surface of the filter bag. On, while the airflow passes through the filter bag to purify. The purified airflow is discharged into the atmosphere through the bag chamber along the pipeline through the fan into the chimney.
As the dust collector thickens the dust adhering to the surface of the filter bag fabric, the resistance of the dust collector is continuously increased. This requires regular cleaning to reduce the resistance below a certain lower limit, and the dust collector can operate normally. The entire cleaning process is mainly carried out by the action of the high-pressure gas storage bag, the electromagnetic valve, the blowing pipe and the cleaning control mechanism. First, the control system automatically activates the solenoid valve in sequence, and the high-pressure air is blown back through the blowing pipe, so that the dust adhering to the filter bag is shaken and falls off and enters the ash bucket. The solenoid valve is then closed, the cleaning operation of the system is completed, and the filter bag is returned to the filtered state. The control system then opens other solenoid valves and cleans the other filter bags. All the filter bags are cleaned and pulverized, thus achieving the purpose of cleaning. The dust collector completely restores the filtering state, and the dust in the ash bucket is bottomed. The ash discharge mechanism collects.
