Description

Technical Field

[0001] The utility model relates to the technical field of furnace dust removal, in particular to a dust removal device for a furnace with a filter screen that is convenient to replace. Background Technique

[0002] A furnace is a type of calcination kiln. According to the heat source classification, it can be divided into a flame kiln and an electric heating kiln. A large amount of furnace flue gas will be generated during the production and use of industrial furnaces. The particulate matter, sulfur dioxide, nitrogen oxides and other toxic and harmful gases discharged from industrial furnaces to the outside must not exceed the national regulations, that is, certain requirements are imposed on the desulfurization and denitrification process equipment. Desulfurization is to remove sulfur dioxide from the flue gas, and denitrification is mainly to remove nitrogen oxides from the flue gas. A large amount of dust particles in the furnace flue gas also need to be removed;

[0003] For example, the Chinese utility model provides a "dust removal device for a furnace with a fan" with the patent number: CN202222953739.7. The patent includes a dust removal box. An air inlet is arranged on the left side of the dust removal box, and an air outlet is arranged on the right side. An air inlet fan is arranged in the air inlet, and an air outlet fan is arranged in the air outlet. When a certain amount of dust accumulates on the filter plate and needs to be cleaned, the cleaning component can automatically clean the dust, so as to facilitate the subsequent continuous purification of the soot, and its dust removal effect is better;

[0004] Although the above document solves the problem that when the existing dust removal device for a furnace actually performs dust removal, it is inconvenient to clean the dust and impurities accumulated on the filter screen for a long time, and it is also easy to affect the purification effect, there is still a disadvantage that the filter component cannot be quickly disassembled, cleaned and replaced. To disassemble the filter screen, the dust removal device needs to be shut down, and the cover plate needs to be opened for disassembly, which will affect the dust removal progress and efficiency. Therefore, a dust removal device for a furnace with a filter screen that is convenient to replace is introduced here. Content of the Utility Model
