Description

Technical Field

[0001] The utility model belongs to the technical field of cyclone separators, in particular to a biomass smoke cyclone separator. Background Art

[0002] In the steam boiler system, the high-temperature flue gas coming out of the biomass circulating fluidized bed furnace contains solid circulating medium and unburned biomass fuel. In order to separate the solid circulating medium and unburned biomass fuel from the flue gas and recycle them, a cyclone separator is generally installed at the outlet of the biomass circulating fluidized bed furnace to separate and recycle them.

[0003] According to the disclosed biomass flue gas cyclone separator (publication number: CN102240614A), the cylindrical cyclone main body is composed of three-stage cyclones, and the side wall of the air inlet of the cyclone is tangent to the side wall of the barrel of the first-stage cyclone. Due to the multi-stage cyclone structure, the material is pulverized after being separated in multiple layers in the circulation process, and smaller materials can be separated out. Therefore, it is more efficient than conventional cyclone separators, and increases the number of material cycles in the boiler, which helps to burn out the fuel, improve the combustion efficiency of the boiler, reduce the feed amount of circulating materials and the slag discharge amount of the boiler, and reduce the workload of the boiler operator. However, in the above-mentioned device, it is difficult to achieve the effect of vibration cleaning by knocking on the filter plate through the mutual cooperation of the cylindrical cyclone main body, the cyclone structure and the air inlet, and it is difficult to knock on the filter plate to effectively remove particles and pollutants attached to the surface, which reduces the performance and efficiency of the separator, increases the damage of the filter plate to the dust accumulation, and thus reduces the service life of the filter plate, which needs to be improved.
