Hazardous waste incineration complete equipment and treatment technology

Abstract

The invention discloses hazardous waste incineration complete equipment and a treatment technology, and belongs to the technical field of hazardous waste treatment. The complete equipment comprises apretreatment and feeding system, an incineration system, a waste heat utilization system, a flue gas treatment system and an ash collecting system; the pretreatment and feeding system comprises a hazardous waste storage area, a vehicle driving grab crane, an elevator, a hazardous waste crusher, a spiral pushing and feeding machine, a hydraulic pushing and feeding machine and a waste liquid feedingmachine; the incineration system comprises a rotary kiln and a secondary combustion chamber which are communicated with each other in sequence; the waste heat utilization system comprises a waste heat boiler and a turbonator connected with the waste heat boiler; the flue gas treatment system comprises a quenching tower, a dry-type deacidification tower, a bag-type dust remover, a flue gas heat exchanger, an acid pickling tower, a neutralizing tower and a chimney; the ash collecting system comprises an ash discharging machine and an ash conveying machine. By means of the hazardous waste incineration complete equipment, heat energy generated by waste heat after incineration can be fully utilized and is converted into electric energy, and the problems of loss and waste of the heat energy inthe prior art are solved.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a complete set of hazardous waste incineration equipment and a treatment process. Background technique [0002] Incineration can effectively destroy toxic and hazardous organic wastes in hazardous wastes, reduce the volume and quality of wastes, and facilitate the final safe disposal of wastes. It is the fastest and most effective technology for reducing and harmless hazardous wastes. After more than 20 years of evolution, the hazardous waste incineration technology has become quite mature, and many different types of waste incinerators have been developed. [0003] Currently, the types of incinerators that can be used to treat industrial hazardous waste mainly include: rotary kiln incinerators, liquid jet incinerators, pyrolysis incinerators, fluidized bed incinerators, and multi-layer incinerators. Among them, the rotary kiln incinerator is currently the main...

AI Technical Summary

Problems solved by technology

[0004] Due to the complex properties of hazardous waste materials, the source is not fixed, the variety changes greatly, and the output fluctuates sharply, it will interfere with the operation of hazardous waste incineration devices to a certain extent.

At present, the complete set of hazardous waste incineration equipment on site does not fully utilize waste heat. Most of them are used as heat sources inside the system or for heat-requiring equipment in the plant, and some are directly emptied, especially in summer, which will cause a great waste of energy.
