Garbage automatic screening guide chamber pyrolysis device

Abstract

The invention discloses an automatic garbage screening, guiding and compartmenting pyrolysis device to overcome the defects that according to an existing garbage pyrolysis treatment device, blockage is likely to happen, dioxin is likely to be generated, and the maintaining and using cost is high. A screening mechanism is arranged below or under a garbage inlet. A solid phase pyrolysis compartment is arranged below the screening mechanism. A gas phase pyrolysis chamber and a wet gas channel are arranged above the screening mechanism. A guiding partition protruding downwards is arranged between the wet gas channel and the gas phase pyrolysis chamber. The automatic garbage screening, guiding and compartmenting pyrolysis device is used for garbage incineration pyrolysis treatment, garbage can be automatically screened while the incineration pyrolysis process is achieved, classifying and compartmenting gradual pyrolysis can be achieved, blockage in the pyrolysis process can be prevented, and environment-friendly pyrolysis preventing dioxin generation is better achieved. Meanwhile, the space utilization rate is high, the occupied space is small, the initial building investment can be reduced, energy consumption is low, auxiliary energy is not needed, and the running and maintaining cost is low.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to a garbage automatic screening guide chamber pyrolysis device. Background technique [0002] Garbage pyrolysis is a waste treatment method widely used in developed countries. In Japan and other countries where arable land is scarce, the proportion of waste incineration and pyrolysis treatment reaches 65-80%. However, the existing waste incineration pyrolysis treatment device has the following disadvantages: [0003] First, the existing waste incineration pyrolysis device cannot automatically screen the waste during the incineration process, and implement classified and gradual pyrolysis, so as to better prevent the stagnation of the incineration process and the generation of dioxins. The existing garbage mixture contains domestic organic matter, plastic, glass, tiles, metal, cement blocks, etc. It is difficult to classify and process before incineration, and the cost is high, so the ...

AI Technical Summary

Problems solved by technology

[0003] First, the existing waste incineration pyrolysis device cannot automatically screen the waste during the incineration process, and implement classification and gradual pyrolysis, so as to better prevent the stagnation of the incineration process and the generation of dioxins

The existing garbage mixture contains domestic organic matter, plastic, glass, tiles, metals, cement blocks, etc. It is difficult to classify and process before incineration, and the cost is high, so the garbage mixture is often used for direct incineration

However, the problem caused by the waste mixture being incinerated directly without screening is that the incineration temperature is difficult to adapt to the organic waste that is prone to dioxin and the inorganic waste that is easy to cause stagnation and affect the incineration state and slag discharge.

The congestion and blockage of the incineration process not only increases the maintenance cost, but also changes the incineration state, affects the control of inhibiting the formation of dioxins in the early stage of incineration, increases the difficulty and cost of subsequent dioxins treatment, and increases the subsequent flue gas purification and removal of dioxins. Possibility of secondary pollution caused by oxins

[0004] Second, the functional unit of the existing incinerator process flow mechanism is horizontally extended, which not only occupies a large area, but also requires a large initial construction investment, and the induced draft fan has high power, high energy consumption, and high operating costs.

In this regard, it is difficult to build without a developed economic foundation and strong investment capabilities

[0005] The third is that 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 operating costs of waste incineration

However, none of these technologies can automatically sieve garbage during pyrolysis to achieve classification and chamber pyrolysis, and it is difficult to prevent pyrolysis stagnation and dioxin generation. The practicability and pyrolysis benefits need to be further improved
