Problems solved by technology

[0002] The existing treatment methods for municipal solid waste include incineration power generation, high-temperature composting, and sanitary landfill. The source of pollution only transfers and conceals the harmful points, and the economic benefits are relatively low
In the prior art, there is a similar gasification method of municipal garbage and a garbage gasification furnace, its patent number: 98111279.x, when the gasification furnace is running, the gasification agent air in the furnace enters from the upper furnace mouth The gasification reaction between the furnace and the garbage molded fuel is downward in the direction, the process is simple, the operation is safe, hygienic and pollution-free, because the garbage molded fuel entering the furnace is first oxidized at the upper part of the furnace to generate high-temperature carbon dioxide and then sucked to the bottom The reducing layer is reduced to combustible gases such as carbon monoxide, and can simultaneously make various harmful combustible components in the garbage briquette undergo high-temperature oxidation treatment in the furnace. When the gasification agent air entering the furnace from the upper furnace mouth undergoes high-temperature oxidation reaction in the upper part of the furnace, the fuel in the lower part of the high-temperature oxide layer in the furnace will form a reduction layer due to lack of oxygen. Since the carbon in the fuel in the reduction layer cannot be fully oxidized, When the high-temperature carbon dioxide generated in the upper part is continuously pumped to the lower reducing layer, it is reduced to combustible gases such as carbon monoxide
Therefore, the carbon content in the ash in the lower part of the furnace is relatively high, resulting in a great loss of energy resources
