Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a garbage incineration flue gas cleaning mechanism. Background Art

[0002] Garbage is discarded items that have lost their use value and cannot be used. It is an important link in the material cycle and is solid and fluid substances that are not needed or useless. The general way to deal with garbage is incineration, but after incineration, it usually produces certain gases, which are mostly composed of carbon dioxide, sulfide and other gases.

[0003] After searching, the application with patent publication number CN217490169U discloses a flue gas treatment mechanism for waste incineration power generation, in which a water tank is fixedly installed on the left upper end of the main frame, a storage box is fixedly installed on the left lower end of the main frame, a hydraulic cylinder is fixedly installed on the right upper end of the main frame, a storage bin is fixedly installed on the right lower end of the main frame, a smoke exhaust pipe is fixedly installed on the right end of the main frame, and filter plates are fixedly installed on the left and middle sides of the main frame, so that the flue gas can be treated by activated carbon.

[0004] However, due to the setting of the filter plate and activated carbon, only carbon dioxide and some dust particles in the flue gas can be adsorbed, while the sulfur dioxide gas produced by combustion cannot be adsorbed, and the flue gas treatment effect is poor. At the same time, due to the large particles of dust in the flue gas, it is easy to cause blockage of the filter plate when it is directly filtered through the filter plate, resulting in a short service life and poor use effect.

[0005] Therefore, we proposed a waste incineration flue gas cleaning mechanism. Utility Model Content
