Mesomorphic substance internal cold shock gasification furnace

Abstract

The invention discloses a mesomorphic substance internal cold shock gasification furnace, and relates to the technical field of coal chemical industries and environments. The mesomorphic substance internal cold shock gasification furnace comprises a vertical cylindrical gasification chamber 2, more than two multi-nozzles 3 and the like, the vertical cylindrical gasification chamber 2 is provided with a high-temperature gas outlet 1, a water cold shock device 5 and a slag-water outlet 6, organic matters in combustible gas, carbon-containing solids and carbon and organic matters in carbon-containing liquid such as oil tar can be simultaneously transformed into synthesis gas, toxic and harmful substances such as dioxin, landfill leachate and heavy metal in the synthesis gas are subjected to high-temperature heat blocking, and coal, urban garbage and organic solid wastes are used in a recycled and clean manner. The gasification furnace can be used for various devices such as low-temperature coal gasification furnaces, coal pyrolysis furnaces, organic solid waste pyrolysis furnaces, rubbish pyrolysis gasification furnaces and coke-oven gas chemical industry devices to perform technicaltransformation of use and deep disposal of coal gas, coke-oven gas, pyrolysis gas, coke powder, pyrolysis residues and toxic and harmful substances, and can be used for newly built devices for organicsolid waste recycling, efficient use of coal, cleaning gasification, IGCC (integrated gasification combined cycle) power generation, urban central heating and the like.

Description

technical field [0001] The invention relates to the technical fields of coal chemical industry and environment. Background technique [0002] In the field of coal chemical industry and environmental technology, due to the high temperature in the slag entrained bed gasifier at home and abroad, the slag contacting the thermocouple causes the insulation material to burst. It is very difficult to measure the temperature in the gasifier. Most of them can only be measured by measuring the gas composition. Or other methods to indirectly measure the temperature, the error is large, and the ash melting point of coal changes greatly, and it is currently impossible to do online detection. This is a very important issue affecting the production and operation of the slag entrained bed gasifier. The problem is even more serious in the countercurrent entrained entrained bed gasifier of coal gas and pulverized coal slag. Due to the difficulty in temperature detection and control, the temper...

Problems solved by technology

It is mainly aimed at the problem of large slag clogging in the lower slag port of the slag countercurrent entrained flow gasifier in the field of coal chemical industry and environmental technology, as well as fixed bed coal gasifier, circulating fluidized bed coal gasifier, coking oven, coal pyrolysis In the production process of industrial furnaces, organic solid waste pyrolysis furnaces, waste pyrolysis gasification furnaces, etc., various combustible gases such as coal gas, coke oven gas, and pyrolysis gas produced contain gaseous phases that need to be utilized and disposed of. At the same time, some solid-phase and liquid-phase carbon-containing substances and toxic and harmful substances such as dioxin, landfill leachate, and heavy metals will be produced. The cost of disposing of these substances separately is high and the technical difficulty is great. , liquid, solid and other carbonaceous substances and toxic and harmful substances such as dioxins, landfill leachate, heavy metals, etc., are simultaneously thermally and chemically disposed of in a multi-phase material internal cooling gasifier
