Hazardous waste multiphase cooperative treatment device and hazardous waste treatment method thereof

Abstract

The invention discloses a hazardous waste multiphase cooperative treatment device and a hazardous waste treatment method thereof, and relates to a hazardous waste treatment device and a hazardous waste treatment method thereof. The problem that a large amount of acid gas and incompletely combusted organic components and furnace slag are generated by incineration of hazardous wastes in an existingincineration method is solved. The hazardous waste multiphase cooperative treatment device comprises an air blower, a feeding machine, a waste liquid tank, a high-pressure oxygen meter, an ammonia water tank, a multiphase reactor, an ammonia water spray gun, a rapid cooler, a dust remover, an induced draft fan, a waste gas spray head, a waste gas tank and a second flue. The process method comprises the steps that solid waste is placed on an air distribution plate of a combustion chamber, the air blower introduces air into the combustion chamber, and the waste liquid tank introduces waste liquid into the combustion chamber for combustion decomposition and waste gas burnout; primary removal is carried out on nitrogen oxide in the flue gas; and the rapid cooler is used for performing secondary denitration and absorbing the heat of the flue gas, then the dust remover is used for filtering particles in the flue gas, and the induced draft fan is used for leading out the flue gas to enter anacid making procedure.

Description

technical field

[0001] The invention relates to a hazardous waste treatment device and a method for treating hazardous waste. Background technique

[0002] With the development of industry, the hazardous waste discharged from industrial production process is increasing day by day. It is estimated that 330 million tons of hazardous waste are generated worldwide each year. Its hazards: 1 damage to the ecological environment. Hazardous waste discharged and stored randomly will pollute water bodies and soil under the long-term infiltration and diffusion of rainwater and groundwater, and reduce the environmental function level of the region. 2 affect human health. Hazardous wastes cause poisoning through ingestion, inhalation, skin absorption, eye contact, or dangerous events such as combustion and explosion; long-term hazards include long-term poisoning, carcinogenicity, teratogenicity, and mutagenesis caused by repeated exposure. 3 Restricting sustainable development.
