Internal heating type pyrolysis device

Abstract

The invention discloses a garbage internal heating type pyrolysis device. The garbage internal heating type pyrolysis device comprises an outer sleeve, a furnace body, a spiral internal heating pipe,a pyrolyzer heat preservation device, an end cover, a motor, a feeding / discharging opening, an impurity outlet device and the like; the outer sleeve of the pyrolysis device is a device for through-flow heating of hot fluid, and heat carried by hot fluid is used for heating materials through furnace body heat transfer; a central shell formed by the outer sleeve is an inner furnace body of the pyrolysis device and is a space for decomposing materials by absorbing heat; the spiral internal heating pipe is used for pushing to-be-pyrolyzed materials entering from the feeding opening to be pyrolyzed by the furnace body and discharged through the discharging opening through rotation a material inlet and a pyrolysis gas outlet are formed in the upper part of a pyrolysis chamber, a pyrolysis residue outlet and a heating medium gas inlet are formed in the lower end of the pyrolysis chamber, and a double-shaft screw is adopted to achieve stirring and propelling effect in the pyrolyzer, and can mutually clean garbage wound on shafts. The garbage internal heating type pyrolysis device has the advantages of being high in reliability, short in pyrolysis time, high in efficiency, good in effect,obvious in decrement, low in pollution, compact in structure, convenient to use and the like, and has wide market prospects in future garbage rear-end treatment.

Description

technical field [0001] The invention provides a pyrolysis device for processing dry components of domestic garbage, especially suitable for pyrolysis and gasification of classified treated domestic garbage, especially dry components after classified and dried. Background technique [0002] With the development of the global economy and the continuous improvement of human living standards, people's material life is becoming more and more abundant, and the amount of domestic waste is increasing rapidly, which has a great impact on the natural environment and has become an important factor affecting social development. In order to reduce the impact of domestic waste, humans currently mainly dispose of domestic waste in three ways: landfill, composting and incineration. At present, although the construction cost of urban domestic waste in my country is low by landfill, ranging from 150,000 yuan / ton to 400,000 yuan / ton, its processing capacity is far from being able to solve the ...

Problems solved by technology

At present, although the construction cost of urban domestic waste in my country is low by landfill, ranging from 150,000 yuan / ton to 400,000 yuan / ton, its processing capacity is far from being able to solve the speed of garbage generated by current social development. At the same time The water pollution caused by the leachate produced after the landfill, the air pollution caused by the landfill caused by the decomposition of organic matter in the garbage, and the soil pollution caused by a large amount of glass, batteries and plastics in the garbage entering the soil are no longer applicable. The trend of today's social development has been gradually eliminated

Composting technology has the defects of large area, long production cycle, difficulty in industrial production, leachate odor and biogas. At the same time, the products produced have low effective fertilizer content and high heavy metal content. Due to the above reasons, their sales are relatively sluggish.

The increasing shortage of traditional energy and the frequent emergence of energy security issues, the use of incineration to speed up the speed of waste disposal, but the huge flue gas treatment equipment brought about by the excess air volume, as well as the infrastructure brought about by ash transportation and treatment, leachate treatment and other links The investment is large, and the problem of dioxins produced during the combustion process is internationally recognized as a highly toxic substance, which has fatal hazards and serious effects on the human body and the surrounding environment.
