Pyrolyzer for treating combustible components in household garbage

Abstract

The invention relates to a garbage pyrolyzer, which comprises an outer jacket, a furnace body, shaft-free screws, an inner heating pipe, a pyrolyzer heat preservation device, an end cover, a motor andthe like, wherein a pyrolysis chamber is arranged in the pyrolyzer, a material inlet and a pyrolysis gas outlet are formed in the upper portion of the pyrolysis chamber, a pyrolysis residue outlet and a heating medium gas inlet is formed in the lower end of the pyrolysis chamber, the two groups of the shaft-free screws play role in stirring and propelling in the pyrolyzer, and a gas discharge port is connected with a gasification device through a pipeline. According to the invention, the garbage pyrolyzer has the advantages of high reliability, short pyrolysis time, high efficiency, good effect, obvious decrement, low pollution, compact structure, convenient use and the like, and has wide market prospects in future garbage rear-end treatment.

Description

technical field [0001] The patent of the present invention provides a pyrolysis device for treating combustible components of domestic waste, especially suitable for pyrolysis and gasification of combustible dry components after domestic waste is mechanically treated by ultra-high pressure dry-wet separation. Background technique [0002] The main technical means of domestic waste disposal are landfill and waste incineration. With the development of society and the acceleration of urban processes, people's material life is becoming more and more abundant, and the output of daily life garbage is increasing. Environmental issues have become an important factor affecting social development. At present, the problem of low efficiency of urban domestic waste recycling in my country is also limited by land resources and ecological environment. Although the construction cost of landfill treatment is low, ranging from 150,000 yuan / ton to 400,000 yuan / ton, but Its processing capacity ...

AI Technical Summary

Problems solved by technology

At present, the problem of low efficiency of urban domestic waste recycling in my country is also limited by land resources and ecological environment. Although the construction cost of landfill treatment is low, ranging from 150,000 yuan / ton to 400,000 yuan / ton, but Its processing capacity is far from being able to solve the speed of garbage generated by the current social development. At the same time, water pollution caused by leachate generated after landfill, air pollution caused by landfill gas generated by the decomposition of organic matter in garbage, and garbage The soil pollution caused by a large amount of glass, batteries and plastics entering the soil has not adapted to the trend of today's social development and has been gradually eliminated

The use of incineration treatment speeds 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 investment brought about by ash transportation and treatment, leachate treatment and other links, and the problem of dioxins generated during the combustion process It is an internationally recognized highly toxic substance, which has fatal hazards and serious effects on the human body and the surrounding environment.
