Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to an incinerator for waste gas treatment. Background Art

[0002] Incinerator is a harmless treatment equipment commonly used in the harmless treatment of medical and domestic waste and animals. Its principle is to use the combustion of fuels such as coal, oil, and gas to burn and carbonize the objects to be treated at high temperature to achieve the purpose of disinfection. At the same time, the incinerator is a kind of environmental protection equipment that burns waste gas, waste liquid, solid waste: such as toxic gas (paint exhaust), toxic rocket liquid fuel, medical waste, domestic waste, animal carcasses, etc. at high temperature to reduce or shrink the quantitative number, and at the same time utilize part of the thermal energy of the incineration medium. It is divided into fixed incinerators and movable incinerators.

[0003] In the related technology, since the incinerator will generate dust during the waste gas treatment process, it will pollute the air of the living environment. In order to prevent the dust in the flue gas from being discharged into the air, the incinerator will install a flue bag at the exhaust pipe port to prevent the dust in the flue gas from being discharged into the air. However, the incinerators currently used have complicated steps and difficult operation when installing the flue bag at the exhaust pipe port. Moreover, after long-term use, the gradually increasing dust on the inner wall of the flue bag causes damage to the incinerator, and it needs to be replaced in time. For this reason, we propose an incinerator for waste gas treatment.

[0004] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content
