Embodiment Construction

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Such as figure 1 Shown, a kind of power generation device based on supercritical water oxidation treatment of domestic waste, including domestic waste disposer 1, supercritical water generator 2, turbine power generation device 5, the supercritical water produced by supercritical water generator 2, and Domestic waste is mixed together and enters the domestic waste disposer 1 for oxidation reaction. After the domestic waste is oxidized, it is decomposed into inorganic substances and combustible gases. It flows in the runner, circulates to absorb the heat of the external environment, and pressurizes, so that the carbon dioxide before entering the turbine power generation device 5 is in a...

Abstract

The invention discloses a power generation device for treating household garbage based on supercritical water oxidation. The power generation device comprises a supercritical water generator, a household garbage treater and a turbine power generation device, wherein supercritical water produced by the supercritical water generator is mixed with household garbage, and the mixture enters the household garbage treater, so that the garbage is oxidized and decomposed into inorganic matters and combustible gas; and a circulating flow channel is further arranged in the turbine power generation devicein a sealing manner, carbon dioxide flows in the flow channel, absorbs external heat in a circulating manner and is pressurized, the carbon dioxide is in a supercritical state before entering the turbine power generation device, the carbon dioxide is sprayed into the turbine power generation device at a high speed after being combusted by the combustible gas, power is generated in a circulating manner, and the generated inorganic matters can be used after being dried. According to the scheme, by the supercritical water oxidation characteristic, the household garbage is treated into the inorganic matters and the combustible gas, the combustible gas is combusted, and after the supercritical carbon dioxide is heated, the turbine power generation device is pushed to generate the power, the inorganic matters are used after being dried, and the household garbage is harmlessly treated.

Description

technical field [0001] The invention relates to the technical fields of chemical engineering and environmental engineering, in particular to a power generation device and method for treating domestic garbage by supercritical water oxidation. Background technique [0002] With the rapid economic development, accelerated urbanization, and continuous improvement of residents' living standards, the amount of urban domestic waste has continued to increase. At present, there are more than 600 cities in my country, and the amount of urban domestic waste is increasing at a rate of 7% to 8% per year. . Economic development has also made it difficult to find suitable landfill sites around cities. Therefore, the problem of municipal solid waste disposal in our country is quite serious; [0003] As for the treatment of domestic waste, it is generally used to fill up or incinerate. Since domestic waste contains a large amount of organic matter, after landfilling, it will cause pollution...
