Abstract

The invention discloses a crushing pretreatment system for hazardous wastes, which relates to the technical fields of environmental protection, waste crushing, hazardous waste treatment and the like. The crushing pretreatment system for hazardous wastes comprises a first roller conveyer, a vertically placed automatic elevator, a second roller conveyer, a chute, a feeder, a shear type crusher, a mixer, a screw conveyer and a plunger pump which are connected sequentially. A safe and explosion-proof tank is arranged over the chute. Compared with the prior art, the crushing pretreatment system for hazardous wastes is integrated with the functions of solid waste crushing, system sealing, powered conveying, system safety and explosion proofing and the like, and has the characteristics of safety, reliability, convenience and applicability.

Description

technical field [0001] The invention relates to the technical fields of environmental protection, garbage crushing and hazardous waste treatment, in particular to a crushing pretreatment system for hazardous wastes. Background technique [0002] With the rapid development of economy and the acceleration of industrialization, the output of hazardous waste is increasing. In 2010, the national hazardous waste production was 15.87 million tons, with a daily disposal capacity of 17,795 tons, of which 73.9% was incinerated; 21.2% was landfill; 4.9% was comprehensive utilization. It can be seen that the amount of hazardous waste generated in my country is far greater than the amount of disposal, and the disposal rate needs to be improved. The disposal process of hazardous waste is mainly incineration. The improvement and improvement of the incineration process system is the key to improving the disposal efficiency, the foundation for achieving the harmlessness and reduction of wa...
