Garbage comprehensive processing system

Abstract

The invention discloses a garbage comprehensive processing system. The system comprises a garbage dehydrating facility, which can carry out spinning-drying and air-drying treatments on garbage; a garbage sorting facility, which can separate organic substances from the dehydrated garbage; an anaerobic fermentation facility, which can fully degrade organic matters to generate biogas; a thermal generator, which can utilize the biogas that has been purified to generate electric; and a fertilizer-producing facility, which can utilize the organic dregs after the degradation of the organic matters to produce organic fertilizer. The garbage automatic dehydrating facility comprises a cylinder, in which a plurality of plugholes are arranged, an radial blowing pipe, which is arranged in the cylinder, and an axial blowing pipe pointing at the front end of the cylinder. The garbage is subjected to spinning drying and air drying before the organic matter is separated from the garbage, thus the sorting efficiency is improved, and the garbage comprehensive processing efficiency is increased. Furthermore, the internal wall of the cylinder can be cleaned to prevent the plugholes being obstructed.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a garbage comprehensive treatment system for comprehensively treating organic matter sorted out of garbage that has undergone spin-drying and air-drying treatment. Background technique [0002] At present, my country's urban domestic waste is increasing at a rate of 10% every year, and the urban waste that implements simple treatment only accounts for 2.3% of the total. 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 year. China has become the country with the heaviest burden of garbage in the world, and the harmless, volume re...

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 dehydrate;

[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
