Recycling hazardous waste treatment system and treatment method by synergizing rotary kiln and plasma gasification

Abstract

The invention relates to a recycling hazardous waste treatment system and treatment method by synergizing a rotary kiln and plasma gasification. The system comprises a hazardous waste storage device, a hazardous waste sorting device, a rotary kiln incinerator, a plasma gasification furnace, a first crushing feeder and a second crushing feeder. The hazardous waste sorting device sorts hazardous wastes in the hazardous waste storage device, and easily handled hazardous wastes are fed into the first crushing feeder and hardly handled hazardous wastes are fed into the second crushing feeder; the first crushing feeder is connected to a feed inlet of the rotary kiln incinerator, and the second crushing feeder is connected to a feed inlet of the plasma gasification furnace. Through a reasonable design, hazardous waste harmless treatment is realized by virtue of technological advantages of the rotary kiln and the plasma gasification, so that the problem of dioxin and heavy metal pollution is avoided. Synthesized gas generated by gasification by the plasma gasification furnace supplements energy required by the rotary kiln, and meanwhile, a high energy utilization ratio of the system is achieved through recovered heat of a waste heat boiler.

Description

technical field [0001] The invention belongs to the field of harmless and resourceful disposal of solid hazardous waste, and in particular relates to a hazardous waste treatment system and method for coordinated resource utilization of a rotary kiln and plasma gasification. Background technique [0002] In recent years, due to the rapid development of science and technology and the improvement of human living standards, the output of solid waste has increased and its composition has become more and more complex. Countries also attach great importance to the treatment and disposal of solid waste. With the continuous improvement of our country's comprehensive strength, our country has become the largest manufacturing country in the world. As the factory of the world, my country's solid waste production cannot be ignored. [0003] Due to the wide variety and complex composition of hazardous solid waste (hereinafter referred to as hazardous waste), my country announced and for...
