Garbage progressive grading pyrolysis device capable of preventing generation of dioxin

Abstract

The invention discloses a garbage progressive grading pyrolysis device capable of preventing generation of dioxin. In order to overcome the defects that an existing garbage pyrolysis device is prone to generate dioxin, auxiliary energy sources are needed, the garbage processing cost is high, the effect is poor, and the efficiency and benefits are low, the garbage progressive grading pyrolysis device is characterized in that primary heat transporting pipes are arranged below a garbage inlet; secondary heat transporting pipes are arranged under the primary heat transporting pipes; at least two primary heat transporting pipes are horizontally placed in a spaced mode; convex spines are arranged on the primary heat transporting pipes; and at least two secondary heat transporting pipes are vertically placed in a spaced mode. The garbage progressive grading pyrolysis device capable of preventing generation of the dioxin is mainly used for harmless environment-friendly up-to-standard processing of household garbage and medical garbage; the effect that garbage incineration pyrolysis does not generate the dioxin is achieved, and hence the dioxin processing cost and the auxiliary fuel consumption 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, the effect is good, and the efficiency and benefits are high.

Description

technical field [0001] The invention relates to a rubbish pyrolysis device, in particular to a progressive graded pyrolysis device for preventing dioxin formation. 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 treatment ...

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
