Abstract

The invention discloses a coal gasification furnace, a coal gasification system and a preparation method of active coke and relates to the technical field of coal gasification. The invention aims at solving the problem of tedious and complex preparation process of the active coke in the prior art. The coal gasification furnace comprises a gasification area, an activation area and a communication channel, wherein the activation area is positioned under the gasification area; the communication channel is communicated with the gasification area and the activation area; the activation area is internally provided with a primary activation spraying nozzle and a secondary activation spraying nozzle; the secondary activation spraying nozzle is positioned under the primary activation spraying nozzle; semicoke and crude coal gas generated from gasification reaction of raw coal in the gasification area are introduced into the activation area through the communication channel; active coke intermediates are generated by primary activation reaction between the semicoke and primary activation gas sprayed from the primary activation spraying nozzle; the active coke is generated by secondary activation between the active coke intermediates and secondary activation gas sprayed from the secondary activation spraying nozzle.

Description

technical field [0001] The invention relates to the technical field of coal gasification, in particular to a coal gasification furnace, a coal gasification system and a method for preparing active coke. Background technique [0002] Coal gasification refers to the gasification reaction of raw coal in specific equipment at a certain temperature and pressure, such as coal hydrogenation gasification, coal pyrolysis, etc., into combustible gases containing CO, H2, CH4, tar, semi-coke, etc. , to improve the utilization efficiency of raw coal and reduce environmental pollution. At present, after the gasification reaction of raw coal, semi-coke and crude gas containing CO, H2, CH4, tar, etc. are generated, among which semi-coke is usually used as a raw material for preparing active coke. [0003] In the prior art, when semi-coke is used as a raw material to prepare active coke, the preparation of semi-coke and the preparation of active coke are usually carried out separately, that...
