Garbage pyrolysis method

Abstract

The invention discloses a garbage pyrolysis method, which comprises the following steps: firstly, putting a piece of garbage into a garbage negative-pressure storage unit for negative-pressure treatment, and drying the garbage subjected to the negative-pressure treatment; then, sorting the dried garbage according to types, and separating organic perishable substances, inflammable and non-perishable substances, building wastes and recoverable substances from the garbage; and finally, respectively carrying out high-temperature fermentation treatment on the separated organic perishable substances, carrying out incineration on the separated inflammable and non-perishable substances, performing high-temperature sterilization and crushing treatment on the separated building wastes, and classifying and recycling the separated recoverable substances. According to the invention, the garbage can be fundamentally eliminated, the garbage in a garbage bin can be more effectively utilized, and the construction cost and the operation cost of urban garbage treatment are effectively reduced.

Description

technical field [0001] The invention relates to converting solid waste into useful or harmless things, more specifically to a comprehensive treatment method and system for urban waste. Background technique [0002] With the continuous development and progress of human beings and the strengthening of environmental protection awareness, there are more and more types of waste contained in urban garbage, and the treatment of urban garbage has attracted more and more attention from the world's environmental protection organizations and environmental protection organizations in various countries. Traditional urban waste disposal methods, such as fuel injection combustion and incineration, slag landfill, or direct burial of waste suction, have obvious shortcomings. First, the waste is not fundamentally eliminated and occupies a large area; Second, the waste gas and toxic gas produced by the fuel injection combustion-supporting incineration method cause secondary pollution to the en...

Problems solved by technology

Traditional urban waste disposal methods, such as fuel injection combustion and incineration, slag landfill, or direct burial of waste suction, have obvious shortcomings. First, the waste is not fundamentally eliminated and occupies a large area; Second, the waste gas and toxic gas produced by the fuel injection combustion-supporting incineration method cause secondary pollution to the environment; third, the waste in the garbage has not been effectively utilized; and the existing garbage disposal methods still exist. Disadvantages of high cost and operating costs
