Problems solved by technology

[0004] In short, the incineration method is not a good way to dispose of domestic waste. Sanitary landfill also has land occupation, large emissions of greenhouse gases, and hidden dangers of pollution. Waste classification and composting methods also have to face the problem of outlets for unusable parts, which is a headache. The problem of "garbage besieged city" must be solved. Therefore, human beings are eager to have a technical solution for the perfect disposal of domestic waste.

Abstract

The invention provides a calcium oxide and plasma body cooperative gasified domestic garbage gasification system and equipment, which relate to solid organic waste disposal equipment. The gasification system consists of a plasma body gasification furnace, an air sealing material feeding device, a heat exchanger, a draught fan and a cyclone separator, wherein a material outlet of the air sealing material feeding device is connected to a material inlet of the gasification furnace, a thermolytical air outlet of the gasification furnace is connected to a carbonatation reaction chamber of the heatexchanger, a hot carrier outlet of the heat exchanger is connected to a hot carrier inlet of the gasification furnace, the hot carrier outlet of the gasification furnace is connected to the cyclone separator, the cyclone separator is connected to the draught fan, the draught fan is connected to a thermolytical air inlet of the heat exchanger, a thermolytical air outlet of the heat exchanger is connected to a thermolytical air inlet of the gasification furnace, and a synthesis air outlet is connected out at the engagement position of a thermolytical region and a gasification region. The systemcan realize the domestic garbage disposal without discharge or pollution, and is applicable to the harmless disposal of urban domestic garbage, rural domestic garbage, medical garbage, industrial high molecular waste materials and the like.

Description

technical field [0001] The invention relates to a solid organic waste disposal system and equipment, in particular to domestic waste disposal equipment. Background technique [0002] With the development of my country's national economy and the continuous expansion of urban scale, domestic garbage and organic waste have increased rapidly, resulting in flooding of garbage. At present, many cities in my country have been surrounded by garbage, which has affected the sustainable development of my country's national economy. Develop and restrict the development of the city. Household garbage and organic waste contain many harmful components. If they are not handled properly, they will pollute the environment and threaten people's health. At present, the treatment of domestic waste mainly includes waste classification and comprehensive utilization, sanitary landfill technology, composting (biochemical) technology and incineration technology. Among them, waste classification requi...
