Integrated pyrolysis and reduction system and garbage disposal method

Abstract

The invention discloses an integrated pyrolysis and reduction system and a garbage disposal method. The integrated pyrolysis and reduction system comprises an anaerobic carbonization kettle, wherein the anaerobic carbonization kettle is provided with an extrusion feeding device which is used for feeding materials and blocking a material port; a heating chamber is arranged below the anaerobic carbonization kettle, the other side of the anaerobic carbonization kettle is communicated with an anaerobic decomposition kettle, the anaerobic decomposition kettle is respectively communicated with a thermal chemical reaction kettle and a waste residue oxidation chamber through a heating pipe, the thermal chemical reaction kettle is located above the waste residue oxidation chamber, a water seal type ash discharging port is formed below the waste residue oxidation chamber, a plurality of gas collecting pipes are arranged above the anaerobic carbonization kettle and the anaerobic decomposition kettle, and the gas collecting pipes are communicated with the thermal chemical reaction kettle. By the adoption of the anaerobic carbonization kettle, the extrusion feeding device, the anaerobic decomposition kettle, the thermal chemical reaction kettle, the waste residue oxidation chamber and the like, application space of garbage disposal is expanded, and generation conditions of pollutants of dioxins are controlled from sources.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to an integrated pyrolysis reduction system and a garbage treatment method. Background technique [0002] Our country produces more than 150 million tons of domestic waste every year, and these wastes cannot be effectively treated and utilized, seriously polluting the environment. After emergencies or natural disasters, various hazardous wastes are left behind, which directly pollute the environment and endanger the safety of rescuers. The recent incident of dead pigs floating on the Yangtze River has once again become the focus of people's attention and news, bringing great pressure to the government. [0003] my country's waste disposal is still dominated by landfill, accounting for about 80%, and landfill is not a long-term solution. With the rapid development of urbanization, land problems have become more and more prominent, and the site selection of waste landfills has encou...

Problems solved by technology

Because incineration is easy to produce secondary pollution, it is difficult for most mobile equipment to meet the national emission standards; some equipment consumes a lot of energy in order to meet the emission standards; for example, the processing capacity of some equipment is only 200kg / h, and the fuel consumption is as high as 80 kg / h

From the current point of view, the existing mobile equipment for solid waste treatment has a small processing capacity and a single treatment object; such as a mobile medical waste treatment vehicle, the treatment object can only be medical waste, and the treatment capacity is only 25-35 per hour.
