Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors for garbage incineration projects, in particular to a new cleaning room for bag dust collectors. Background Art

[0002] Because the conversion rate of volatile chlorine in garbage into HCl is 100%, the conversion rate of combustible sulfur into SO2 is also close to 100%, and the conversion rate of nitrogen into NOx is 10%, the flue gas of the garbage incineration project contains a large amount of HCl, SO2 and NOx. In the existing design, the double-layer door part has no insulation and the door frame at the door cover sealing position is very easy to leak air, which causes condensation between the top cover plate and the inner layer of the double-layer door in the dust collector cleaning room, reacting with HCl, SO2 and NOx in the flue gas to generate an acidic solution, which causes serious corrosion to the cleaning room, and thus the dust collector needs to be cleaned.

[0003] Through patent search, it was found that the publication number: CN220194464U discloses a general industrial waste incineration flue gas purification system, including a denitrification device, a deacidification device and a dust removal device. The denitrification device includes: an SNCR reactor and an SCR reactor; the deacidification device includes: a semi-dry deacidification reaction tower, and the dust removal device includes: a first-stage bag dust collector, a second-stage bag dust collector and a third-stage bag dust collector. While ensuring that the outlet flue gas meets the emission standards, it reduces the total disposal cost of fly ash generated in the flue gas purification system process, thereby reducing the daily operating cost of general industrial solid waste disposal projects. Utilizing the denitrification and deacidification processes of the flue gas, the three bag dust collectors are respectively arranged at different positions between the denitrification equipment and the deacidification equipment to ensure that the main components of the fly ash absorbed by each dust collector are different, and each dust collector is connected to different fly ash treatment equipment, without having to be connected to the hazardous waste treatment equipment.

[0004] During the production and installation of existing bag-type dust collectors, the sealing effect of the double-layer door of the clean room does not meet the expected design effect, and air leakage occurs during use; secondly, the double-layer door has no heat insulation, and the temperature difference between the inside and outside of the equipment is large, which is prone to condensation. In order to solve the above problems, a new clean room for bag-type dust collectors is proposed in this application. Utility Model Content
