Introduce what are the two dust removal methods for biomass boiler dust collectors

　　There are two types of dust removal methods for biomass boiler dust collectors: cyclone dust collector and bag dust collector. The cyclone dust collector is used to separate solid and liquid particles from the air stream. According to the different cleaning methods, the bag filter can be divided into three types: mechanical vibration, air flow reverse blowing and pulse blowing.

　　Mechanical vibration cleaning is often used in dust collectors with small air volume. The airflow back-blowing ash cleaning effect is better than mechanical vibration, and the allowable filtering speed is lower, so the equipment is larger in scale, the pressure loss of the equipment is larger, and the area is larger. The pulse jet has strong dust cleaning ability and good effect. It can allow higher filtration speed, the equipment pressure loss is small, the floor space is small, and the energy consumption is low.

　　The processing technology of the biomass dust collector is to treat the flue gas generated during the production of each boiler separately. The flue gas produced by the boiler. The dust enters the cyclone dust collector through the dust suction pipe. At this time, the large particles in the dust are separated under the action of the centrifugal force of the cyclone dust collector, the large particles of dust are discharged by the cyclone dust collector, and the fine particles of dust enter the bag filter. Filtered by the filter bag, the dust adhering to the surface of the cloth bag is concentrated in the ash hopper of the dust collector through pulse blowing, and then recycled or utilized by the feeding controller. The clean air processed by the bag filter is discharged into the air from the chimney through the fan. The dust-containing flue gas of the boiler is treated by the bag filter, which can reduce the pollution of the flue dust to the surrounding environment and achieve the purpose of clean production.
