Garbage environmental protection and high efficiency pyrolysis device

Abstract

The invention discloses an environment-friendly efficient pyrolysis device for garbage. In order to overcome the defects that existing garbage pyrolysis is prone to generate dioxin which pollutes the environment, poor in pyrolysis effect, high in processing cost and operating cost and the like, the environment-friendly efficient pyrolysis device is characterized in that a garbage input mechanism communicates with a primary pyrolysis cavity which communicates with a secondary pyrolysis cavity; the primary pyrolysis cavity is provided with a plurality of horizontally-placed hot air pipes and vertically-placed hot air pipes under the horizontally-placed hot air pipes at intervals; the horizontally-placed hot air pipes are rotationally connected with a power mechanism; convex spines are arranged on the horizontally-placed hot air pipes; the secondary pyrolysis cavity is provided with a plurality of hot air spraying pipes at intervals; and protecting walls are arranged outside the hot air spraying pipes. The environment-friendly efficient pyrolysis device is used for processing the household garbage, the medical garbage and the like; the garbage subjected to incineration pyrolysis through the environment-friendly efficient pyrolysis device cannot generate dioxin, and thus the dioxin processing cost and the auxiliary fuel cost can be reduced; in addition, the structure is simplified, and the manufacturing cost and the using cost are low; and garbage incineration pyrolysis processing is quick and thorough, the effect is good, and the efficiency and benefits are high.

Description

technical field [0001] The invention relates to a garbage harmless treatment device, in particular to an environmentally friendly and efficient pyrolysis device for garbage. 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 and pyrolysis t...

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 requires a lot of auxiliary energy, and the utilization efficiency of the heat generated by waste incineration itself is not high enough, resulting in 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
