An integrated device for plasma fly ash melting and synthesis gas purification

Abstract

The invention discloses an integrated device for plasma fly ash melting and synthesis gas purification, which comprises a synthesis gas purification furnace body, the upper wall of the synthesis gas purification furnace body is provided with a multi-nozzle swirl burner, and the lower part of the synthesis gas purification furnace body is Plasma generators are arranged at intervals on the wall surface, and a baffle separator is installed below the plasma generator in the body of the synthesis gas purification furnace. The center of the baffle separator is connected to the heat conduction base, and a built-in tar The catalytic bed and the bottom of the synthesis gas purification furnace body are provided with a slag outlet. The invention is applicable to the technical field of pyrolysis gasification synthesis gas purification of solid organic fuels such as garbage and biomass. The melting of fly ash in the synthesis gas can be realized, and the tar can also be catalytically cracked in the process, so as to realize the thorough purification of the synthesis gas and provide the basis for the subsequent use of diversified utilization methods.

Description

technical field [0001] The invention belongs to the technical field of purification of synthesis gas after solid organic fuel gasification, and in particular relates to an integrated device for plasma fly ash melting and synthesis gas purification. Background technique [0002] With the rapid development of the country's economy, the generation of organic solid waste led by municipal solid waste has increased sharply, and the problem of disposal is imminent. [0003] At present, my country's waste treatment mainly adopts landfill, composting and incineration. Landfills are prone to produce methane-rich landfill gas, causing explosions, and a large amount of landfill leachate, which contains heavy metals, toxic and harmful organic chemical pollutants, and a large number of viral pathogens. Due to the imprecise classification of waste in the composting method, the fertilizer quality is low and difficult to sell. When the incineration method is used to treat municipal solid w...

AI Technical Summary

Problems solved by technology

[0007] However, the use of plasma to melt fly ash usually consumes a lot of electric energy, and a lot of heat is wasted during melting and cannot be used effectively

And because the fly ash in the waste gasification synthesis gas exists in a state of dusty gas, if the whole synthesis gas is heated to the melting temperature, it will consume a lot of energy
