Solid waste incineration cyclone furnace and incineration process for liquid slag of solid waste incineration cyclone furnace

Abstract

The invention discloses a solid waste incineration cyclone furnace and an incineration process for liquid slag of the solid waste incineration cyclone furnace. A pre-chamber is arranged at the top end of a secondary combustion chamber and the top end of a cyclone; the top of the pre-chamber is connected with a spray burner; the spray burner is connected with solid waste conveying equipment; the secondary combustion chamber is connected at one side of the cyclone; a gas exhaust opening of the secondary combustion chamber is connected with a waste heat utilization and tail gas treatment device; a slag outlet of the secondary combustion chamber is connected with the bottom of the cyclone through an inclined conveying device; a slag bar is arranged on the bottom of the cyclone; and a kettle opening used for collecting flowing slag is formed in the slag bar. A liquid slag-discharge incineration process for the solid waste incineration cyclone furnace can incinerate multiple industrial wastes such as solid waste, thick asphalt waste and waste gas, realizes liquid discharge, and can realize waste heat utilization.

Description

technical field [0001] The invention relates to the field of medical and chemical hazardous waste treatment, in particular to a solid waste incineration cyclone furnace and an incineration process for liquid slag discharge. Background technique [0002] With the continuous development of the national economy, enterprises and institutions in the chemical industry and other industries produce more and more hazardous wastes. These hazardous wastes include solid hazardous waste, viscous asphalt hazardous waste, liquid hazardous waste, high Salt hazardous waste, emulsified hazardous waste, etc. In recent years, with the increasingly stringent national environmental protection policies, on the one hand, the hazardous waste produced by hazardous waste production enterprises has increased significantly, and the hazardous waste has not been treated in a timely and effective manner and has accumulated in the factory area; on the other hand, the hazardous waste disposal unit has insuff...

Problems solved by technology

In recent years, with the increasingly stringent national environmental protection policies, on the one hand, the hazardous waste produced by hazardous waste production enterprises has increased significantly, and the hazardous waste has not been treated in a timely and effective manner and has accumulated in the factory area; on the other hand, the hazardous waste disposal unit has insufficient processing capacity and cannot Meeting the Rapid Increase in Hazardous Waste

Improper storage, utilization, treatment and disposal of hazardous waste will not only easily cause air, water and soil pollution, seriously affect the ecological environment and the health of the people, but also restrict the sustainable development of the economy.

[0003] At present, the domestic treatment of hazardous waste and domestic waste basically uses rotary kilns or small fluidized bed boilers. The temperature in the furnace is low, the combustion effect is not good, and the viscous asphalt material cannot be treated or the treatment is not ideal, which is easy to cause blockage. Feed port and kiln wall fall off

Rotary kiln and small fluidized bed treatment are only simple combustion treatment, waste heat is not utilized, resulting in energy waste, and environmental protection treatment is not ideal

Both rotary kiln and small fluidized bed are solid slag discharge, it is difficult to realize the liquid slag discharge process, the waste residue after treatment is easy to cause secondary pollution and difficult to recycle
