Abstract

The invention provides a gasification slag cooling device and a gasification slag cooling method.The gasification slag cooling device comprises a gasification unit used for carrying out gasification reaction on fuel and a gasification agent in the gasification unit and generating slag within a first temperature range; the slag cooling unit is provided with a fluidization cooling medium inlet, and the fluidization cooling medium inlet is used for introducing a fluidization cooling medium with a preset temperature and a preset air speed, so that the slag in the first temperature range can be cooled to the first temperature range under the fluidization transportation and impact physical cooling action of the fluidization cooling medium; the first particle size slag in the second temperature range and the second particle size slag in the second temperature range are formed.

Description

technical field [0001] The present disclosure relates to the technical field of hydrocarbon fuel energy chemical industry, and in particular, the present disclosure relates to a gasification cold slag device and a gasification cold slag method. Background technique [0002] Coal gasification is one of the core technologies for clean and efficient utilization of coal, and it is the basis for the development of coal chemical process industries such as coal-based chemicals, coal-based clean fuels, industrial gas and polygeneration systems. The fluidized bed gasifier uses pulverized coal as the raw material, the gasification agent and the pulverized coal are gasified in a fluidized form, and solid slag is discharged. The fluidized bed gasifier has the advantages of strong adaptability to coal types, no tar in the gas, and high gasification intensity. [0003] At present, in the slag cooling system of the fluidized bed gasifier, due to the unreasonable design of the cooling slag...
