Abstract

The incineration pretreatment process comprises a mixing device, a combustion chamber, an explosion venting device and a secondary combustion chamber, the mixing device, the combustion chamber, the explosion venting device and the secondary combustion chamber are sequentially connected through pipelines according to the flowing path of flue gas generated after incineration, and the mode that the high-chlorine waste liquid enters the combustion chamber from the mixing device is atomized spraying. And the secondary combustion chamber is connected to a rotary kiln main incineration line secondary combustion chamber through a pipeline. The combustion chamber is mainly used for conducting primary combustion on the high-chlorine waste liquid, the secondary combustion chamber is used for conducting sufficient combustion on combustible smoke generated in the combustion chamber, a proper amount of lime slurry is sprayed in the combustion chamber in the incineration process, a large amount of chlorine-containing smoke is removed through an adsorption reaction, and combustible substances in the smoke are further combusted after further combustion in the secondary combustion chamber; flue gas enters a secondary combustion chamber of a main incineration line to be completely combusted after being treated and is discharged after reaching the hazardous waste incineration pollution control standard, and the buffering effect of protecting the rotary kiln is achieved.

Description

technical field

[0001] The invention relates to the technical field of hazardous waste treatment, in particular to an incineration pretreatment process for high-chlorine waste liquid. Background technique

[0002] Hazardous waste can be classified into solid hazardous waste, liquid hazardous waste, and viscous hazardous waste according to its form. For liquid hazardous waste, incineration is an effective treatment method. Incineration can effectively destroy toxic organic substances in waste liquid. It is an effective means for the reduction and harmlessness of hazardous waste. Rotary kiln incineration is currently the mainstream process for hazardous waste incineration treatment. The design of rotary kiln is suitable for continuous feeding and treatment of solid hazardous waste, and is widely used in hazardous waste incineration systems;

[0003] With the continuous development of industry, the composition of hazardous waste produced by waste production enterprises is beco...
