A garbage disposal and recycling device

Abstract

The invention discloses a garbage treating and recycling device which comprises a garbage water removal treating unit, a garbage classifying device, an anaerobic digestion unit, a thermoelectric generator unit and a fertilizer preparing unit, wherein the garbage water removal treating unit is used for spin-drying and air-drying garbage and comprises a rotation device and an air barrel; a plurality of water outlets are distributed in the rotation device; the air barrel is arranged in the rotation device; air blowing holes facing the water outlets are formed in the air barrel; the garbage classifying device can be used for classifying organic matters from garbage after spin-drying and air-drying; the anaerobic digestion unit is used for enabling organic materials in the organic matters to be fully decomposed to generate biogas; the thermoelectric generator unit is used for generating power by using the biogas after purification; the fertilizer preparing unit is used for preparing an organic fertilizer preparing from biogas residues after the organic matters are fully decomposed to generate the biogas. According to the garbage treating and recycling device, the organic matters are classified from the garbage after spin-drying and air-drying, so that the classifying efficiency of the organic matters is improved, and the comprehensive garbage treating efficiency is quickened; in addition, the garbage can be subjected to spin-drying and air-drying simultaneously, so that the water removal process can be greatly quickened.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a garbage treatment and reuse device for comprehensive treatment of organic matter sorted out from garbage. Background technique [0002] At present, our country's municipal solid waste is increasing at a rate of 10% every year, while the simple treatment of urban waste only accounts for 2.3% of the total. At present, the area of ​​arable land occupied by our country's garbage stockpiles over the years is about 500 million square meters, and the direct economic loss is as high as 8 billion yuan. The number of cities across the country has grown to 660, and 200 of them have been surrounded by garbage. Based on an urban population of 260 million and each person producing 440 kg of waste per year, the amount of waste generated is 114 million tons, which can cover a city with a population of 1 million by 1 meter. And it is still increasing at a rate of 8-10% every ...

AI Technical Summary

Problems solved by technology

[0004] 1. Mixed and received ingredients are complicated, and the content of bags is high;

[0005] 2. High water content, the average water content is 50%, and the limit water content is as high as 70%;

[0006] 3. The content of kitchen waste and muck is high, and it is difficult to separate and remove water;

[0007] 4. The content of perishable substances is high, and improper handling will cause serious secondary pollution

[0011] 1. The operating environment is harsh and the secondary pollution is serious: the method of draining water and fermentation and evaporation is used to remove water, which has a long cycle, a large amount of malodorous gas emissions, a large amount of landfill leachate, and high COD and BOD content in the leachate. Treatment costs are high ;

[0012] 2. Affected by the change of garbage moisture, the performance of fermentation products is extremely unstable
