Hazardous waste treatment system

Abstract

The invention provides a hazardous waste treatment system, and relates to the field of hazardous waste treatment. The hazardous waste treatment system comprises a solid-liquid separation device, a crushing device and an incineration device, wherein a solid outlet and a liquid outlet are formed in the two sides of the solid-liquid separation device respectively, a conveying device is arranged at one end of the solid outlet in the solid-liquid separation device, and the other end of the conveying device is connected with the crushing device; a liquid discharge pipe is connected to one side of a liquid outlet in the bottom of the solid-liquid separation device, a waste liquid treatment device is arranged at one end of the liquid discharge pipe, a discharge port of the crushing device is connected with a feed port of the incineration device through a pipeline, a cooling furnace is arranged at one side of the incineration device, and a stirring device is arranged on the upper side wall of the cooling furnace; and a gas treatment device is arranged at one side of the upper end of one side wall of the cooling furnace. The hazardous waste treatment device has the advantages that solid hazardous waste and liquid hazardous waste can be separated and treated respectively, and the treatment efficiency is high.

Description

technical field [0001] The invention relates to the field of hazardous waste treatment, in particular to a hazardous waste treatment system. Background technique [0002] Hazardous wastes refer to wastes that are included in the national list of hazardous wastes or that are identified as having hazardous characteristics according to the national hazardous waste identification standards and identification methods. With the development of industry, more and more hazardous wastes are discharged in the process of industrial production. These hazardous wastes will bring serious pollution and potential serious impact on the ecological environment and people's health. The hazardous wastes produced in industry include liquid hazardous waste, solid hazardous waste Waste and gaseous hazardous waste, etc. [0003] Among them, solid hazardous waste and liquid hazardous waste are easily mixed together, and it is impossible to effectively separate liquid hazardous waste from solid hazard...

AI Technical Summary

Problems solved by technology

[0003] Among them, solid hazardous waste and liquid hazardous waste are easily mixed together, and it is impossible to effectively separate liquid hazardous waste from solid hazardous waste, which increases the difficulty of hazardous waste treatment, and most of the hazardous waste treatment methods currently use incineration. However, after incineration of hazardous waste, residues and gases will be produced. The temperature of the residue after incineration is relatively high, and most of them are treated by natural cooling, which takes a long time and has poor cooling efficiency. In addition, the gas produced after incineration will also contain harmful substances and floating dust, etc. These gases cannot be treated, and it is easy to cause secondary pollution to the environment.
