Dust Removal Process of Soldering Fume Extractor When running, the dust is filtered by the dust bag, and some dust stays on the outer surface of the dust bag to form a gray cake layer. In order to control the resistance to the limited range, there is no differential pressure transmitter or a time relay in the dust collector, and the dust removal chamber and the net gas chamber are detected online.

When the pressure difference reaches the set value, a signal is sent to the controller, and the control instructions will be issued by the control instruction to turn on the various pulse valves in order, so that the compressed air in the airbag is sprayed from each hole of the spray pipe to the corresponding dust removal bags, causing the dust removal cloth bag Instantly swelling.

Under the action of negative pressure airflow, the dust -containing gas quickly enters the dust from the entrance of the separator, filter through the dust bag bag, is separated from the air flow, and the purified clean gas enters the clean gas chamber from the inside of the dust bag. This can achieve the effect of dust removal, a process of filtering dust.

The differential pressure transmitter is used to determine the pressure difference between the net gas chamber and the dust chamber of the separator, and transmit it to the control room. When the pressure difference reaches the set value, the signal will be sent, the instruction controller action, and then it will be caused by the movement of the controller. The pulse valve realizes the anti -blowing bag of dust bags, thereby completing the periodic cloth bag update. When the differential pressure transmitter exceeds the low limit setting value, the differential pressure transmitter sends a signal indicator separator cloth bag that is damaged. At this time, it should be stopped to check and repair.
