Efficient drying treatment equipment for garbage

Abstract

The invention discloses efficient drying treatment equipment for garbage. The efficient drying treatment equipment for the garbage comprises a roller with a plurality of water outlets distributed, a radial blowing pipe, a feeding device, an air supply device and an axial blowing pipe. The radial blowing pipe is mounted in the roller, and a plurality of air outlets facing water outlets are formed in the radial blowing pipe; the feeding device is communicated with an inlet of the roller, and the air supply device is connected with one end of the radial blowing pipe; the axial blowing pipe is connected with the air supply device and is aligned at the front end of the roller; and the other end of the radial blowing pipe is a closed end. A cabin door opening or closing an outlet of the roller is mounted on the outlet of the roller, and an air inlet of the air supply device is connected with a hot air outlet of a garbage incinerator through a pipeline. According to the equipment, hot air generated by garbage incineration is utilized for carrying out drying treatment on garbage while garbage is dried in a spinning manner, and therefore the drying 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 high-efficiency drying treatment equipment for 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 year. China has become the country with the heavi...

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
