Industrial kiln co-processing method and equipment for hazardous wastes

Abstract

The invention discloses an industrial kiln co-processing method for hazardous wastes. The method comprises the following steps: hazardous waste raw material treating; mixing, molding and processing; efficient feeding; and comburent treating. By classifying, drying and crushing hazardous waste raw materials, mixing and forming the hazardous waste raw materials, and combining an efficient feeding mode, the hazardous waste raw materials have higher combustion efficiency and treatment effect in the actual combustion treatment process, so that the pollution of the hazardous waste raw materials to the environment is reduced, resource loss of a combustion boiler is reduced, production cost of enterprises is reduced, economic and environment-friendly benefits are jointly improved, and the problems that in the prior art, hazardous waste with different water contents cannot be subjected to classified drying treatment, so that hazardous substances are separated out due to the fact that hazardous waste with low water content is heated and dried excessively, secondary harm is caused, and raw materials with high water content cannot be effectively dried, so that the subsequent combustion efficiency is low, and the raw materials cannot be better treated are solved.

Description

technical field [0001] The invention relates to the technical field of hazardous waste disposal, in particular to a method and equipment for industrial kiln coordinated disposal of hazardous waste. Background technique [0002] Hazardous waste refers to solid waste or solid waste that has one or several hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity, or infectivity, and does not exclude wastes with hazardous characteristics, and may cause harmful effects on the environment or human health. Liquid waste is treated as hazardous waste, and with the development of society, the amount of hazardous waste is gradually increasing. It is far from meeting the treatment needs only through the existing treatment facilities. Therefore, it needs to be processed through industrial The technology of kiln co-processing hazardous waste to dispose of hazardous waste realizes the effective use of energy and resources in hazardous waste and reduces the produc...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method and equipment for industrial kiln co-processing of hazardous waste, which can effectively solve the problem of the current co-processing technology proposed in the above background technology. Due to the lack of effective treatment of hazardous waste during the disposal process, the subsequent co-processing of hazardous waste During the process, its combustion efficiency cannot meet the disposal standard, which not only affects the normal production of the enterprise, but also easily causes the phenomenon of secondary treatment. Moreover, the existing hazardous waste generally needs to be dried, and the existing technology in the drying process Due to the inability to classify and dry hazardous waste with different moisture content, hazardous waste with low moisture content will precipitate harmful substances due to overheating and drying, causing secondary hazards, while raw materials with high moisture content cannot be effectively dried treatment, and then make its subsequent combustion efficiency low, and it is impossible to carry out better disposal problems
