Problems solved by technology

[0015] 1) The plasma gasification device system is used, which consumes a lot of electric energy, and the cost of waste treatment per unit mass is high;
[0016] 2) The waste treatment capacity of a single furnace is small, it is not easy to be large-scale, and it is difficult to scale up industrially
[0020] 1. The flue gas dries the garbage, the exhaust gas temperature is high, and the sensible heat contained in the high-temperature flue gas is not fully utilized;
[0021] 2. In the process of waste incineration, it is easy to produce toxic gases such as malodorous gas, greenhouse gas and dioxin, which is not good for the environment;
[0022] 3. Biomass energy and volatile matter contained in garbage have not been rationally utilized

specific Embodiment

[0053] Such as figure 1 with figure 2 As shown, it includes a waste pretreatment system and a waste pyrolysis system. The waste pretreatment system includes: the accumulation of incoming waste, the pre-sorting of waste, and the packaging and shaping of waste.

[0054] The modular waste pyrolysis system includes gas inlet / outlet system, pyrolysis gas outlet system, combustion chamber, honeycomb heat storage body, pyrolysis chamber and insulation layer. among them:

[0055] The gas inlet / outlet system relies on the three-way valve program to control the opening and closing of the valve to realize the switching of fuel gas intake and combustion and hot flue gas exhaust.

[0056] The two ends of the combustion chamber are the combustion control system, which can realize low-temperature exhaust after the flue gas at the other end exchanges heat with the honeycomb regenerator when the intake air is combusted at one end. The honeycomb heat storage body can act as a medium to realize the ...

Embodiment 1

[0062] The composition analysis of domestic wax waste in a certain city is shown in the table below. The water content of the waste is 46%.

Description

Technical field [0001] The invention relates to a garbage treatment system, in particular to a garbage pyrolysis treatment system and method. Background technique [0002] With the acceleration of my country's modernization process, municipal solid waste has become an important factor restricting the rapid development of green cities. At present, the treatment methods of municipal waste in various countries in the world mainly include sanitary landfill, incineration, composting, pyrolysis and comprehensive waste treatment. However, my country's related waste classification and comprehensive waste utilization technologies are lagging behind. At present, the main waste disposal methods are sanitary landfills, supplemented by incineration and composting. Moreover, with the advancement of science and technology and the enhancement of environmental protection awareness, the destructive effects of "incineration" and "landfilling" to the environment and threats to human health have bee...
