Solid waste treatment system with hazardous waste pretreatment process

Abstract

The invention relates to the field of waste treatment devices, in particular to a solid waste treatment system with a hazardous waste pretreatment process. The system comprises a crushing box; a V-shaped discharging plate is arranged on the portion, close to the middle, of the crushing box; a discharging valve is fixedly installed on the lower surface of the V-shaped discharging plate; a crushingchamber is arranged between the V-shaped discharging plate and the inner wall of the upper side of the crushing box, a crushing mechanism is arranged in the crushing chamber, and a feeding hopper is fixedly installed on the portion, close to the left side, of the crushing box. Solid waste is crushed through the crushing mechanism, so the volume of the solid waste is smaller; a large amount of heatdischarged by an incineration mechanism enters the crushing chamber through a heat conduction mechanism, solid waste is dried, the moisture content is reduced, the incineration time of the solid waste is short, combustion is more sufficient, discharged smoke can be conveniently filtered through a filtering mechanism, the environment is better protected, and waste attracted by magnets such as ironcan be recycled through a conveying mechanism.

Description

technical field [0001] The invention relates to the field of waste treatment devices, in particular to a solid waste treatment system with a hazardous waste pretreatment process. Background technique [0002] Solid waste refers to solid, semi-solid, and gaseous items placed in containers that lose their original use value or have not lost their use value but are discarded or abandoned during production, living and other activities, especially chemical waste. The solid waste discharged by the factory is usually toxic and harmful to the environment. Therefore, this kind of waste is called hazardous solid waste. The existing hazardous solid waste is generally directly incinerated through an incinerator. During use, there will be the following problems: [0003] When dealing with solid waste with hazardous waste produced by chemical plants, it is directly put into the incinerator for incineration. Due to the different sizes, the incineration time required for incineration is al...

AI Technical Summary

Problems solved by technology

[0003] When dealing with solid waste with hazardous waste produced by chemical plants, it is directly put into the incinerator for incineration. Due to the different sizes, the incineration time required for incineration is also different, resulting in incomplete incineration and hazardous solid waste disposal. The effect is not good. In the process of incinerating hazardous chemical solid waste, toxic and harmful gases will be produced. These gases are directly discharged into the air, causing pollution to the environment. At the same time, a large amount of heat contained in the discharged gas cannot be used, causing resource Waste, most of the devices are static during purification, resulting in average efficiency, and the cleaning of the filtration and purification mechanism is time-consuming and laborious
