Garbage anhydration processing apparatus

Abstract

The invention discloses a garbage anhydration processing apparatus, which comprises a roller, an air pipe, a feeding device and an exhaust fan, wherein a plurality of water outlet holes are distributed in the roller; the air pipe is mounted in the roller; a plurality of air outlet holes facing the water outlet holes are formed in the air pipe; the feeding device is communicated with an inlet of the roller; an air outlet of the exhaust fan is connected to one end of the air pipe; the other end of the air pipe is a sealed end; a cabin door used for opening or sealing the outlet of the roller is mounted at the outlet of the roller; an air inlet of the exhaust fan is connected to a hot air outlet of a garbage incinerator by a pipeline. While garbage is spin-dried by the invention, the garbage is subjected to anhydration treatment by hot air which is generated by garbage incineration, and thus the anhydration process of the garbage is greatly accelerated.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a garbage drying treatment equipment. 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 has become the country with the heaviest burden of garbage in...

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
