Abstract

The invention provides a dry distillation gasification device which comprises a gasification furnace, a gasification pipeline, a fan and a gas-solid separator, wherein a material is sent to the gasification pipeline through a feed inlet and mixed with gas in a pipeline system to form a gas-solid mixture; the material is subjected to dry distillation and gasification in the gasification pipeline; the gas-solid mixture is driven by the fan to circulate in the pipeline system; solids in the gas-solid mixture are separated by the gas-solid separator and discharged from a solid outlet, and gas after gas-solid separation returns the gasification pipeline through a gas return port; and finished gas can be discharged from a finished gas discharge pipe. The pulverized coal containing volatile matters is subjected to rapid dry distillation, most of the volatile matters of the coal are gasified and converted into gas fuel, and meanwhile, residual coal particles are used for producing activated carbon.

Description

technical field [0001] The invention relates to coal powder dry distillation technology in coal chemical industry, in particular to a dry distillation gasification device and a coal powder fast dry distillation method. Background technique [0002] The dry distillation of coal mainly includes continuous vertical carbonization furnace, gasification furnace, coking gas production and other forms. However, these methods do not allow the product gas to participate in recirculation to heat the pulverized coal, nor do they have such a rapid heating rate during the gasification process, reaching 0.13 seconds. [0003] Coal topping (a scientific and technological project supported by the national 863 plan) is implemented by using the high-temperature hot ash of coal semi-coke burned by the boiler as the heat carrier of raw coal to realize the entire process technology route, which belongs to the solid heating method. The coal is quickly pyrolyzed and separated in less than 1 second...
