Boiler pulse bag filter is a kind of equipment widely used in industrial dust control, especially in boiler flue gas dust removal. The dust collector uses pulse cleaning technology, which uses compressed air to spray instantaneously, so that the dust is quickly removed and falls into the ash hopper. Compared with traditional mechanical rapping dust collectors and wet dust collectors, pulse bag filters have higher dust collection efficiency, greater processing capacity, and a wider range of applications.
1. The structure and working principle of the pulse bag filter.
The pulse bag filter is mainly composed of ash hopper, box, pulse valve, injection device and control system. The working principle is that the flue gas enters the dust collector through the air inlet and is filtered through the filter bag, and the dust is trapped on the surface of the filter bag. Over time, the dust on the surface of the filter bag gradually increases, causing the resistance to rise. When the resistance reaches a certain value, the control system will issue a cleaning command. At this time, the pulse valve is opened, and the compressed air is instantly sprayed into the filter bag, blowing off the dust on the surface of the filter bag and falling into the ash hopper. After a period of operation, the dust in the ash hopper accumulates to a certain amount and can be discharged through the ash discharge device.
Second, the advantages of pulse bag filter.
1.High dust removal efficiency: The pulse bag filter adopts high-efficiency filter materials, which can effectively filter out the dust particles in the flue gas, so that the discharged flue gas meets the environmental protection standard.
2.Large processing capacity: Due to the use of pulse cleaning technology, the dust collector can run continuously and has a large processing capacity, which is suitable for flue gas treatment of large boilers.
3.Convenient maintenance: The structure of the pulse bag filter is simple, and the parts are easy to disassemble and replace, which is convenient for maintenance and maintenance.
4.Wide range of application: Pulse bag filter is suitable for various types of boiler flue gas treatment, such as chain furnace, circulating fluidized bed furnace, etc.
5.Low energy consumption: Compared to traditional wet dust collectors, pulsed bag filters have lower energy consumption and lower operating costs.
3. The application range of pulse bag filter.
1.Industrial boilers: Pulse bag filters are widely used in various types of industrial boiler flue gas treatment, such as boilers in chemical, papermaking, building materials, electric power and other industries.
2.Urban heating boiler: The flue gas treatment of urban heating boiler is also suitable for pulse bag filter, which can effectively reduce the emission of pollutants in the flue gas.
3.Other fields: Pulse bag filter is also used in dust control in metallurgy, ceramics, machinery and other industries.
