Garbage sorting system

Abstract

The invention discloses a garbage sorting system. The system comprises a garbage dehydrating facility, which carries out spinning drying and air drying on garbage; a garbage delivering facility, which is arranged in the outlet of the garbage dehydrating facility and is used to deliver the dehydrated garbage; and a garbage sorting facility, which is arranged on the outlet of the garbage delivering facility, and is used to receive the dehydrated garbage and separate organic matters, inorganic matters, and wastes from the dehydrated garbage separately. The garbage dehydrating facility comprises a roller, in which multiple plugholes are arranged; a radial blowing pipe, which is arranged in the roller; and an axial blowing pipe pointing at the front end of the roller. The garbage is subjected to spinning drying and air drying at the same time, and moreover, the internal wall of the roller is cleaned after the spinning drying and air drying, so the garbage dehydration is largely accelerated, and the garbage sorting is also accelerated.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a garbage sorting and processing system for sorting garbage that has been spin-dried and air-dried. 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 in 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...

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

[0013] In addition, waste with high moisture content tends to clump into balls, which reduces the efficiency of waste sorting
