Abstract

The invention relates to a household garbage pyrolysis treatment method. The method includes: the garbage added with pyrolysis catalyst is fed into a pyrolysis drum machine, the high-temperature heat of a incinerator heats the outer wall of the pyrolysis drum machine, the garbage continuously rolls along with the rotation of the pyrolysis drum machine and slowly advances, the garbage is continuously heated, dried and pyrolyzed in sequence, the pyrolysis temperature inside the pyrolysis drum machine is controlled at about 200 DEG C, the garbage discharged from the pyrolysis drum machine is subjected to dechlorination to become high-quality solid fuel, part of the solid fuel enters the incinerator for incineration so as to provide heat for the pyrolysis drum machine, and surplus part of the solid fuel can be used for efficient power generation in a centralized manner. The method is low in investment, operation cost and secondary pollution, and applicable to city and countryside garbage disposal plants, generation of dioxin can be controlled fundamentally, and the surplus part of the high-quality solid fuel can be used for efficient power generation in a centralized manner.

Description

One way of life refuse pyrolysis processing method

Technical field

The present invention relates to one way of life waste disposal method, relate in particular to one way of life refuse pyrolysis processing method.

Background technology

China is mainly direct burning electricity generation to the heat treatment method of house refuse present stage.Directly burning electricity generation investment is huge, operation cost is high, secondary pollution is serious, particularly produces the violent in toxicity bioxin that makes common people's fear, makes burning electricity generation project site selection very difficult; And the chlorine corrosion directly burning due to rubbish restricted the generating efficiency of waste incineration, approximately low by 50% than common thermal power generation efficiency, also cause the huge waste of the energy.

Summary of the invention

In order to overcome, the direct burning electricity generation processing method investment of existing house refuse is huge, operation cost is high, secondary pollution is serious and the deficiency of energy waste, the invention provides a kind of waste disposal method, this waste disposal method small investment, operation cost is low, secondary pollution is few, house refuse after this method is processed becomes the same high-quality fuel of class sapropelitic of black, chlorine component in the plastic containing chlorines such as PVC has been removed, except processing the energy as domestic garbage pyrolysis coalification, part more than needed can be concentrated for high efficiency generating utilization.

The object of the present invention is achieved like this: the rubbish that has added pyrolysis catalysts is knocked down in pyrolysis roller machine, the high temperature hot gas of incinerator heats to pyrolysis roller machine outer wall, rubbish constantly rolls with the rotation of pyrolysis roller machine and moves forward lentamente, rubbish is constantly heated, priority is through the process of drying and dehydrating, pyrolysis, in pyrolysis roller machine, the temperature of pyrolysis is controlled at 200 degree left and right, guarantee that the chlorine component in the plastic containing chlorines such as PVC fully decomposes out, control the further pyrolysis gasification of plastics simultaneously.Rubbish from pyrolysis roller machine out, through dechlorination, process and to have become high-quality solid fuel, a part enters incinerator and burns, for pyrolysis roller machine provides heat, part more than needed can be concentrated for high efficiency generating utilization.The mists such as the steam that pyrolysis roller machine produces, pyrolysis gas are introduced into depickling dechlorination tower, deduster, through air-introduced machine, introduce incinerator high-temperature process.Incinerator hot gas by pyrolysis roller machine absorbing and cooling temperature after, be introduced into extracting tower, deduster, through air-introduced machine, introduce chimney and enter in atmosphere.This waste disposal method small investment, operation cost is low, secondary pollution is few, particularly fundamentally can control the generation of bioxin, and suitable urban and rural domestic refuse is processed and used.

The invention has the beneficial effects as follows, process house refuse small investment, operation cost is low, secondary pollution is few, particularly fundamentally can control the generation of bioxin, the high-quality fuel of part more than needed can be concentrated for high efficiency generating utilization.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the invention will be further described.

Fig. 1 is city house refuse treatment method process chart.
