Garbage energy saving and environmental protection efficient pyrolysis device

Abstract

The invention discloses an energy-saving environment-friendly efficient pyrolysis device for garbage. In order to overcome the defects that existing garbage pyrolysis is prone to generate dioxin pollution, insufficient in pyrolysed heat utilization, poor in processing effect, high in operating cost and the like, the energy-saving environment-friendly efficient pyrolysis device is characterized in that a primary pyrolysis cavity communicates with a secondary pyrolysis cavity through a flue gas channel, the secondary pyrolysis cavity is connected with a flame gas heat exchanging mechanism through a flame gas output mechanism, and the flame gas heat exchanging mechanism communicates with the primary pyrolysis cavity and the secondary pyrolysis cavity through a hot air conveying mechanism. The energy-saving environment-friendly efficient pyrolysis device is mainly used for processing the household garbage and the medical garbage; flame gas heat energy of garbage incineration can be fully utilized and converted into oxygen-rich hot air with different temperatures, the oxygen-rich hot air with the different temperatures can be supplied to the pyrolysis cavities in different pyrolysis sections, and thus incineration pyrolysis generating dioxin can be prevented; and the energy-saving effect is remarkable, the implementation cost and the operating cost are low, and the effect and benefits are good.

Description

technical field [0001] The invention relates to a waste incineration pyrolysis device, in particular to a waste energy-saving, environment-friendly and high-efficiency pyrolysis device. Background technique [0002] Waste incineration pyrolysis is a high-temperature thermochemical treatment technology. The combustible components in the waste react with oxygen in the air in the incinerator and are converted into high-temperature gases and solid residues. The pyrolysis process of waste incineration produces a large amount of heat energy, which can reduce the volume by 80%-90%. It can destroy the composition and structure of harmful solid waste, kill pathogenic bacteria, and achieve the purpose of detoxification and detoxification. It has the advantages of reduction, harmlessness, and resource utilization. It is one of the waste treatment methods widely used in developed countries. In Japan and other countries where arable land is scarce, the proportion of waste incineration an...

AI Technical Summary

Problems solved by technology

[0003] One is that the incineration process of the existing waste incineration pyrolysis device will generate a large amount of dioxins

Dioxin treatment is difficult and expensive

Although the research and understanding of dioxin-like substances have been deepened in recent years, technically through the "3T" control of incinerators and strict incineration flue gas purification process, the emission of dioxin-like substances can be controlled within strict standards However, the one-time investment and operating costs are greatly increased, and the dioxin-like substances removed by flue gas purification still have secondary pollution

[0004] Second, the existing waste incineration pyrolysis device needs a lot of auxiliary energy, but the utilization efficiency of the heat generated by waste incineration itself is not high enough, resulting in high energy consumption and high cost of waste incineration

[0005] Third, the structure of the existing incineration device is complex, the manufacturing cost is high, the one-time investment for purchase and use is large, and the project construction takes a long period of funds

However, these technologies have a large one-time investment, high operating costs, unsatisfactory effects, and poor practicability
