Description

Technical Field

[0001] This utility model relates to the field of gasification furnace technology, specifically a gasification furnace for treating industrial hazardous waste. Background Technology

[0002] A gasifier is a device used to convert solid or liquid fuels into gaseous fuels. It is primarily used in coal chemical and biomass energy fields, utilizing the chemical reaction between fuel and atmosphere at high temperatures to generate combustible gases. These gases can be used as fuel or further processed into other chemicals or liquid fuels. Gasifiers mainly convert solid fuels into gaseous fuels through reactions such as cracking, gasification, and reforming, achieving efficient resource utilization.

[0003] Chinese Patent Publication No. CN216972441U, authorized on July 15, 2022, discloses a gasifier for treating industrial hazardous waste. The gasifier includes a gasifier shell, within which, from top to bottom, are arranged a combustion chamber, a heat recovery chamber, and a saline wastewater evaporation chamber. A central burner is located at the top of the gasifier shell, surrounded by several auxiliary burners. The central burner contains a coal-water slurry channel and an oxygen channel, while the auxiliary burners contain a waste liquid channel and a combustible waste gas channel. Addressing the technical problem of existing gasifiers' poor treatment effect on industrial hazardous waste, this invention provides a gasifier for treating industrial hazardous waste that effectively utilizes the organic calorific value of industrial hazardous waste, conserves coal resources, and reduces carbon emissions.

[0004] When adding industrial hazardous waste, the existing gasifier requires frequent opening of the gasifier's feed inlet cover for manual feeding. When the cover is opened, steam and ash escape from the furnace, posing a safety hazard and reducing the gasifier's processing efficiency, thus failing to meet usage requirements.
