Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a filtering and purifying device for waste gas equipment. Background Art

[0002] Thermal power generation is the main power generation method in my country. It uses the heat energy generated by the combustion of combustibles and converts it into electrical energy through a power generation device. Since thermal power equipment uses the combustion of combustibles to generate electricity, the air inside the thermal power equipment will contain a large amount of dust and other impurities. The direct emission of these dusts not only pollutes the environment, but also affects the health of the workers, so they need to be filtered and treated; however, the existing thermal power equipment mostly relies on simple filtration of filters for dust treatment, which not only leads to poor filtration effect of exhaust gas emitted by thermal power equipment, but also the filter directly filters the dust, causing dust to accumulate quickly on the surface of the filter, thereby reducing the filtration efficiency of the filter and even causing clogging problems. Therefore, the filter needs to be replaced and cleaned frequently, and the loading and unloading and cleaning process is relatively troublesome. In addition, simple filter filtration cannot effectively purify the harmful substances in the exhaust gas, so the exhaust gas also requires other devices to cooperate in purification, thereby reducing the practicality of the device.
