Small energy-saving and efficient domestic garbage incinerating treatment system

Abstract

The invention relates to a small energy-saving and efficient domestic garbage incinerating treatment system. The small energy-saving and efficient domestic garbage incinerating treatment system comprises a before-incineration treatment system, an incinerating system, a smoke gas waste heat utilizing system and a smoke gas treatment system. The smoke gas treatment system comprises a first gas-liquid exchanging device, a first induced draft fan, a waste sodium carbonate utilizing tower, a semi-drying-method extracting tower, a second gas-liquid exchanging device, a cooling water tower, a cyclonedust collector, a bag-type dust collector, a second induced draft fan and a chimney. According to the small energy-saving and efficient domestic garbage incinerating treatment system, the before-incineration treatment system, an incinerating furnace inner structure and the smoke gas treatment system are optimized, convenience of garbage crushing and dewatering is comprehensively considered, the airtightness of an incinerating furnace is improved, garbage sufficient incineration is promoted, secondary pollution is reduced, smoke gas waste heat is sufficiently utilized, sodium carbonate secondary utilization is achieved, pollutants such as acid gas, organic pollutants and particles are more effectively removed, and the purposes that garbage does not fall on the ground, odor is not spread, waste liquid is not discharged, and waste heat is not wasted are achieved.

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.
