Boiler Bag Filter

The boiler bag filter is to treat the flue gas produced in the production process of each boiler separately.

Dust-containing gas enters the filter bag through the flower plate hole, the dust is trapped on the inner surface of the filter bag, and the dust-containing gas is purified by the filter bag. The purified gas enters the bag room, and then passes through the exhaust switch and exhaust pipe of the lifting switch valve , Discharged into the atmosphere by the exhaust fan. Theboiler bag filteris an air outlet at the top, and the internal filter type dust collector is operated under negative pressure. The cleaning method can be divided into two methods: fixed time and fixed resistance. Timing cleaning is based on a time program. Each room automatically performs cleaning in turn according to the adjustable time parameter. The cleaning cycle of the dust collector is 0 to 2.5 hours and can be adjusted in six steps. The cleaning time of each room is 10 seconds to 3 seconds. Six choices. Timing cleaning control is to sample the difference between the inlet and outlet pressure of the dust collector, and convert the differential pressure transmitter into an electrical signal to carry out cleaning. In addition to the above two control methods, the ash controller relay solenoid valve cylinder lift switching valve is also provided with a manual control mechanism, which can manually perform normal ash cleaning control. For the convenience of operation and management, it is recommended to use the regular cleaning method. 4. Temperature control The flue gas temperature of the vertical kiln generally fluctuates in the range of 60-300 °, and the moisture content of flue gas fluctuates in the range of 4-12%. In order to prevent the dew condensation bag and the burning bag due to excessive temperature Wait for a vicious accident to happen.
