Anaerobic cracking treatment device for household garbage

Abstract

The invention discloses an anaerobic cracking treatment device for household garbage. The device comprises: a feeding system, which is used for pretreating raw materials and dividing the raw materialsinto a first material and a second material; a carbonization cracking system, which is used for carrying out pyrolysis treatment on the raw materials conveyed by the feeding system, and comprises a carbonization furnace and a cracking furnace, wherein the carbonization furnace comprises a carbonization part and a carbonization heating jacket, and the cracking furnace comprises a cracking part anda cracking heating jacket; a cracking gas purification system, which is used for purifying gas generated by the carbonization furnace and the cracking furnace; and a combustion system, which is usedfor providing heat required by reaction for the carbonization furnace and the cracking furnace by the gas purified by the cracking gas purification system. The household garbage is divided into two parts to be treated, each part of the household garbage is subjected to pyrolysis treatment in an anaerobic cracking mode, the cracked product can be recycled, and comprehensive utilization of resourcesis achieved.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to an oxygen-free cracking treatment device for domestic waste. Background technique [0002] With the rapid increase of population and the further improvement of living standards, the output of urban domestic waste is increasing day by day. The existing treatment facilities are far from meeting the needs of urban development, and the effect of avoiding neighbors is serious, which cannot meet the requirements of residents for living environment. [0003] The traditional treatment methods of domestic waste include landfill, incineration and pyrolysis, among which landfill needs to occupy a large amount of land resources, and the landfill leachate will cause serious pollution to groundwater and destroy the ecological balance; incineration can reduce the amount of domestic waste and is harmless Pyrolysis is a common way to deal with domestic waste, but it has low econo...

[0002] With the rapid increase of population and the further improvement of living standards, the output of urban domestic waste is increasing day by day. The existing treatment facilities are far from meeting the needs of urban development, and the effect of avoiding neighbors is serious, which cannot meet the requirements of residents for the living environment.

[0003] The traditional treatment methods of domestic waste include landfill, incineration and pyrolysis, among which landfill needs to occupy a large amount of land resources, and the landfill leachate will cause serious pollution to groundwater and destroy the ecological balance; incineration can reduce the amount of domestic waste and is harmless Pyrolysis is a common way to deal with domestic waste, but it has low economic benefits, high costs for follow-up tail gas treatment and residue treatment, and secondary pollution problems; the traditional pyrolysis method belongs to direct heating. Although part of the energy can be recovered, it is also the same There is a problem of residue disposal, and the comprehensive utilization of resources cannot be achieved
