Rapid dewatering device for perishable garbage composting

Abstract

The invention discloses a rapid dewatering device for perishable garbage composting. The device comprises a primary fermentation bin, a secondary fermentation bin and a compression bin; a material transfer channel is arranged between the primary fermentation bin and the secondary fermentation bin, and a material transfer channel is arranged between the secondary fermentation bin and the compression bin; each of the primary fermentation bin and the secondary fermentation bin is provided with an air feeding system, an air extracting system, a stirring and propelling system and a heating system;the primary fermentation bin is also provided with a material feeding assembly; and a compressing and packaging assembly and a discharge chute are arranged in the compression bin. The device overcomeslow calorific values of perishable garbage and technical disadvantages of biomass garbage treatment.

Description

technical field [0001] The invention relates to the field of domestic waste treatment, in particular to a fast dehydration treatment device for composting perishable waste. Background technique [0002] With the continuous growth of my country's national economy, the acceleration of urbanization and the improvement of people's living standards, the urban catering industry is becoming more and more prosperous, and the output of perishable garbage in our country is increasing day by day. It mainly comes from leftovers and food residues from households, canteens of enterprises and institutions, catering services, etc. It has a large amount and a wide range, complex ingredients, high salt content, and is easy to rot and deteriorate. At the same time, it is easy to breed germs and is accompanied by foul smell If it is not specially treated, it will pose a great threat to water, air, soil and even human health. It is a key environmental problem that our country needs to solve urge...

Problems solved by technology

[0003] At present, the treatment and disposal methods of perishable waste in my country are mainly incineration, aerobic composting, anaerobic composting, preparation of biological feed, and landfill. Due to the factors of Chinese food culture, most of the perishable waste is kitchen waste. It is because the water content is relatively high (about 85-90%), which leads to the low calorific value of the waste. When it enters the incineration power plant for incineration, it needs to add combustion-supporting fuel, which increases the operating cost of the waste incineration plant, and the cost of incineration treatment is high and the efficiency is low.

[0004] According to statistics, the annual output of straw is about 900 million tons, and the utilization rate is less than 40%. The output of domestic waste such as garden waste, green waste, and sawdust waste in urban domestic waste is also quite large, which is characterized by low density, loose and porous, and biomass energy. Rich, the current treatment methods are incineration, as compost filler, and landfill, the transportation cost is relatively high, and the treatment efficiency is low
