A small energy-saving and high-efficiency domestic waste incineration treatment system

Abstract

The invention relates to a small-scale energy-saving and high-efficiency domestic waste incineration treatment system, which includes a pre-incineration treatment system, an incineration system, a flue gas waste heat utilization device and a flue gas treatment system. The flue gas treatment system includes the first gas-liquid heat exchange device, the first induced draft fan, residual alkali ash utilization tower, semi-dry deacidification tower, the second gas-liquid heat exchange device, cooling water tower, cyclone dust collector, bag filter , second induced draft fan and chimney. This system optimizes the waste incineration pre-treatment system, the internal structure of the incinerator and the flue gas treatment system, comprehensively considers the convenience of garbage crushing and dehydration, improves the air tightness of the incinerator, promotes the full incineration of garbage, and reduces the generation of secondary pollutants , make full use of the waste heat of flue gas, and use soda ash for secondary use to more effectively remove pollutants such as acid gas, organic pollutants and particulate matter, so as to prevent garbage from falling to the ground, odor from spreading, waste liquid from being discharged and waste heat from being wasted, etc. Purpose.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a small energy-saving and high-efficiency domestic waste incineration treatment system. Background technique [0002] In recent years, the economy of small towns in my country has developed rapidly, and a large amount of domestic waste is produced in the process of production and consumption. If domestic garbage is not disposed of properly, it will not only occupy a certain amount of land and waste land resources, but also emit a bad smell and breed various bacteria. The environmental sanitation infrastructure in small towns is relatively backward, and domestic waste is piled up everywhere, causing obvious problems of dirty, messy, and poor quality. Therefore, it is imperative to rationally dispose of domestic waste in small towns. The treatment and disposal of domestic waste can be divided into three categories: landfill, composting and incineration. Only inci...

AI Technical Summary

Problems solved by technology

[0006] At present, there are some small domestic waste incineration pre-treatment devices on the market, but none of them are relatively general, and all have some defects or deficiencies, such as: the crushing machinery is too expensive, the process is too long, the energy consumption of dehydration is too large, and the waste heat of flue gas is utilized. Insufficient, comprehensive energy consumption is too high, etc.
