Abstract

The invention discloses a fluidized bed destructive distillation method and device of pulverized coal, and solves the problems of large coke burning load and unideal charking effect in the prior art. The destructive distillation provided by the invention includes the steps of: A, mixing pulverized coal raw material (1) with high temperature coal ash, conducting a destructive distillation reaction on the mixture in a destructive distillation dense phase section bed layer of a bed-type destructive distillation reactor (50) to generate oil gas and pulverized coal semicoke; and subjecting the mixture of pulverized coal semicoke and coke ash to stripping in a stripper (10) in steam; B, charking the mixture of pulverized coal semicoke and coke ash subjected to stripping in a charking canister (15) to generate regenerated semicoke; C. charking the regenerated semicoke in a riser reactor (18) to generate coal ash containing coke; and D, charking coal ash containing coke in a charking dense phase section bed layer of a bed type charking device (60) to generate high temperature coal ash. The invention discloses a fluidized bed destructive distillation device of pulverized coal for realizing the above method. The invention can be used for destructive distillation processing of a variety of pulverized coals.

Description

technical field [0001] The invention belongs to the field of coal chemical industry, and relates to a method and device for fluidized bed dry distillation of coal powder. Background technique [0002] my country's rapidly growing demand for crude oil has driven the rapid growth of crude oil imports; under the circumstances of lack of oil and gas resources and rising demand, excessive dependence on foreign oil and natural gas has brought great hidden dangers to my country's energy security and caused many The cost of petrochemical raw materials remains high. Coal chemical industry and petrochemical industry are mutually substitutable, and the development of new coal chemical industry can be a good supplement to petrochemical industry, which has strong strategic significance. Coal chemical industry refers to the process of using coal as raw material and converting coal into gas, liquid and solid fuels and chemicals through chemical processing; it mainly includes coal gasificat...
