Technical Field

[0001] The utility model relates to the field of gasification slag treatment, in particular to a gasification slag treatment waste gas purification mechanism. Background Art

[0002] Gasification slag treatment refers to the solid by-products produced when part of the carbonaceous fuel cannot be completely oxidized during the combustion process. These by-products usually exist in the combustion products in the form of blocks or particles, and have the characteristics of being hard under high temperature and high pressure. Gasification slag is usually disposed of and treated through professional treatment methods such as solid waste landfill and incineration.

[0003] At present, a large amount of waste gas will be generated during the incineration process of gasified slag. However, it is difficult for the current incinerator to efficiently purify the waste gas during the incineration process of gasified slag, and the discharged waste gas will pollute the air environment and affect the overall quality of the air. For this reason, we propose a gasified slag treatment waste gas purification mechanism to solve the above problems. Utility Model Content
