Problems solved by technology

There are many devices involved, high energy consumption, long process and low energy conversion rate of the system
[0004] In the gasification technology with coal gasification as the core, there are high energy consumption and accumulated CO in the process. 2 issues such as large emissions
cause CO 2 The main reasons for the large emissions and high energy consumption are the insufficient contact between the raw material and the gasification agent in coal gasification and the inability to effectively and fully utilize the high-temperature gas generated, and the conversion process consumes a large amount of energy

Description

technical field [0001] The invention belongs to the technical field of coal gasification, and in particular relates to a high-efficiency coal gasification reaction device and a high-efficiency coal gasification reaction method. Background technique [0002] Coal is an important energy source. Coal is used through direct combustion, but direct combustion leads to low coal utilization and pollutes the environment. For this reason, a coal gasification technology has emerged, that is, coal gasification. Coal gasification refers to the gasification reaction of coal in specific equipment at a certain temperature and pressure, and the conversion of coal into gas to improve the utilization of coal. and reduce environmental pollution. [0003] Conventionally, in order to efficiently produce combustible gas by gasifying coal, various coal gasification technologies and systems including fixed bed, fluidized bed, and entrained bed have been studied. The equipment involved is more, the...
