Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a smoke extraction device for a biomass boiler. Background Art

[0002] The smoke extraction device of biomass boiler is mainly used to collect and process the smoke and soot generated during the combustion of biomass fuel. The smoke extraction device is usually composed of flue, filter, fan and other parts. The flue is responsible for guiding the smoke generated by the boiler into the device;

[0003] Some smoke extraction devices are also equipped with filters, that is, the filters intercept and adsorb particulate matter and harmful gases in the smoke through physical or chemical methods, so as to achieve the purpose of purifying the smoke, or use filters to intercept and filter particulate matter in the smoke, so as to prevent a large amount of particulate matter from entering the fan and adhering to the inside of the fan, thereby affecting the normal smoke extraction of the fan, and also reducing the difficulty of maintenance of the fan in the later stage. However, when the existing filter intercepts and filters the smoke, the filter mesh inside the filter mesh is complex due to the smoke generated by the combustion of biomass fuel. It contains a large number of tiny particles and sticky substances. These particles and substances are easy to adhere to the mesh surface when passing through the filter mesh. As time goes by, they gradually accumulate and form blockages. When the filter mesh is blocked, the filter must be disassembled, and the filter mesh must be removed from the filter, and then the filter mesh must be cleaned, resulting in cumbersome cleaning operations.
