High-efficiency vertical domestic garbage treatment device

Abstract

The invention discloses a high-efficiency vertical domestic garbage treatment device, comprising a reactor, wherein the reactor comprises an upper cover and a shell, the shell is internally provided with a screw conveying mechanism I, a screw conveying mechanism II and an auger conveying mechanism, the screw conveying mechanism I and the auger conveying mechanism are vertically arranged on two sides in the shell, the auger conveying mechanism is located at the lower side in the shell, and the screw conveying mechanism I and the screw conveying mechanism II are vertical to each other. The high-efficiency vertical domestic garbage disposal device carries out closed-loop circulating conveying and mixing on materials, so that the materials are mixed and stirred more uniformly, material accumulation is avoided, a certain void ratio exists between the materials, the materials are in sufficient contact with oxygen, and the reaction efficiency is high; the whole biological reaction process iscompleted in a sealed reactor, so that heat loss and odor escape can be avoided during the stirring reaction process; the conversion rate of resources is increased, and treated domestic garbage reaches a standard of clean discharge.

Description

technical field [0001] The invention belongs to the field of domestic waste treatment and relates to a high-efficiency vertical domestic waste treatment device. Background technique [0002] With the development of the economy and the improvement of people's living standards, the output of domestic waste is increasing year by year. At present, the domestic mainstream domestic garbage disposal methods are landfill, incineration power generation and diversified treatment, and landfill is the main treatment method. Landfill not only occupies a large amount of land resources, but also causes serious secondary pollution to land and groundwater; due to the poor classification effect of domestic waste, the calorific value of the material used for incineration for power generation is too low, the power generation efficiency is low, and the dioxin produced by incineration is serious Air pollution poses a threat to people's lives and health; diversified treatment is to sort domestic ...

AI Technical Summary

Problems solved by technology

Landfill not only occupies a large amount of land resources, but also causes serious secondary pollution to land and groundwater; due to the poor classification effect of domestic waste, the calorific value of the material used for incineration for power generation is too low, the power generation efficiency is low, and the dioxin produced by incineration is serious Air pollution poses a threat to people's lives and health; diversified treatment is to sort domestic waste and then process various items, but the existing sorting methods are not thorough in the classification of waste, and its resource utilization rate is not high, therefore, the existing domestic waste disposal methods still need to be further improved

[0003] For example, Chinese patent CN104289497 discloses a multi-stage semi-continuous organic waste biological reaction device and method, which discloses biological reaction treatment of organic waste, which provides a favorable theoretical basis for the treatment of domestic waste, but in practical applications, biological reaction treatment There are still some problems with organic waste. The most important problem is that there is a dead angle in the mixing, and the materials cannot be mixed efficiently and fully, which seriously affects the effect of waste treatment.
