Embodiment Construction

[0023] specific implementation plan

[0024] Such as figure 1 As shown, the gasification, melting and incineration method for treating municipal solid waste is to store the primary crushed waste in the storage bin 1, transport it to the high-temperature air gasification furnace 2 through a fully enclosed belt, and heat it in the high-efficiency regenerator 8 to The high-temperature air of 1000°C to 1050°C is sprayed into the gasification furnace 2 through the conveying / nozzle 3 to gasify the garbage. The air consumption coefficient is controlled within 0.3 to 0.5, so that the combustible components in the solid waste can undergo incomplete combustion reaction in a high temperature environment above 1300°C to 1350°C. Its incombustible components are transformed into liquid slag, and the synthetic gas with higher calorific value is discharged from the upper part of the gasifier 2 into the cyclone dust collector 4 . The smoke and dust from the cyclone dust collector 4 settles i...

Abstract

The present invention provides an urban house refuse gasification melting incineration treatment method and its equipment. It is characterized by that the high-temperature air obtained from waste heat of smoke produced by recovering, gasifying, melting and incinerating refuse can be introduced into gasifying furnace and incinerator furnace, and can be used as air required for refuse gasification and combustion-supporting air required for melting and incinerating refuse, so that it can ensure refuse stable gasification and complete combustion, and can completely solve dioxine and secondary pollution of heavy metals and others. Said treatment equipment system is formed from storage bin, gasifying furnace, dust-collecting device, incinerator furnace and high-effective heat storage chamber, etc.

Description

technical field [0001] The invention relates to a treatment technology of urban garbage, in particular to a method for treating urban domestic garbage by gasification, melting and incineration of high-temperature air and a device for treating urban garbage by gasification, melting, and incineration designed using the method. Background technique [0002] Municipal solid waste disposal has become a common issue faced by countries all over the world. Untreated or improperly treated municipal solid waste will not only encroach on land, pollute groundwater, destroy natural landscapes, but even endanger the safety of people's lives and property. The average annual growth rate of garbage in my country is over 10%, and at least 2 / 3 of the more than 400 cities in China are surrounded by garbage; at the same time, garbage contains a large number of dust pathogens and becomes the source of infection for various diseases. According to the survey on the pollution of garbage piled up in...
