Harmless environmental-friendly treatment system for municipal waste

Abstract

The invention discloses a harmless environmental-friendly treatment system for municipal waste. The harmless environmental-friendly treatment system includes a bottom plate; a barrel body is fixed onthe upper surface of the bottom plate through supporting legs, the right end of the barrel body is opened, the diameter of the barrel body gradually becomes smaller from left to right, a second bearing is installed in a circular hole in the left side face of the barrel body, an inner ring of the second bearing is fixedly connected with the left end of the outer side face of a rotating shaft, the diameter of the inner wall of the barrel body gradually becomes smaller from left to right, the waste is squeezed, the water in the waste drops onto the upper surface of a tile plate through a liquid outlet hole in the lower end of the barrel body, and the heat value of the waste incineration is increased; and a water pump makes the cleaning liquid in an external storage box be discharged through adraining hole in a water outlet pipe, a water inlet gap is formed between the front end of the tile plate and the front side face of the interior of a waste water box, the cleaning liquid brings thewater squeezed from the waste on the upper surface of the tilt plate into the waste water box, the odor evaporation of the water squeezed from the waste is reduced through the tilt plate, the odor ofthe worker environment is reduced, and the working environment of the workers is improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a harmless and environment-friendly treatment system for urban garbage. Background technique [0002] Domestic waste treatment is mainly based on incineration power generation and landfill. Landfill is a waste disposal method with serious pollution. It covers a large area and wastes land resources seriously. Landfill leachate causes serious pollution to the surrounding water environment and land environment. [0003] Incineration power generation is a good waste resource treatment method in theory, but domestic waste in China is mixed waste, which contains a large amount of kitchen waste, and the water content of waste is as high as 50%. The calorific value of direct incineration of waste is very low. Generally around 1000 kcal, and the process of waste incineration needs to consume a lot of other energy such as oil, coal, etc., and the energy recovery rate is less than...

Problems solved by technology

[0002] Domestic waste treatment is mainly based on incineration power generation and landfill. Landfill is a waste treatment method with serious pollution left over. It covers a large area and wastes land resources seriously. Landfill leachate causes serious pollution to the surrounding water environment and land environment.

[0003] Incineration power generation is a good waste resource treatment method in theory, but domestic waste in China is mixed waste, which contains a large amount of kitchen waste, and the water content of waste is as high as 50%. The calorific value of direct incineration of waste is very low. Generally around 1000 kcal, and the process of waste incineration needs to consume a lot of other energy such as oil, coal, etc., and the energy recovery rate is less than 50%. In the process of waste incineration, due to the low calorific value of waste and low furnace temperature, the incineration process is easy to produce Toxic and harmful gases such as dioxin, etc.; the moisture in the garbage has a strong odor, and the working environment for workers is poor
