a gasifier

Abstract

The invention discloses a gasification furnace and relates to the technical field of coal gasification equipment. It was invented to solve the problem that the content of semi-coke particles in the synthesis gas discharged from the existing gasifier is relatively large, and the burden of subsequent gas-solid separation is relatively heavy. The gasification furnace of the present invention includes a shell, the top wall of the shell is provided with a raw material inlet, the side wall of the shell is provided with an exhaust port, the bottom wall of the shell is provided with a coke discharge port, and the shell is provided with a built-in guide. Flow tube, swirl inner tube and swirl member, one end of the built-in flow guide tube communicates with the raw material inlet, and the other end extends downward; the swirl inner tube is sleeved outside the lower end of the built-in flow guide tube, and the swirl inner tube The upper end extends upwards to a position close to the exhaust port, a first annular gap is formed between the inner wall of the swirl inner cylinder and the built-in guide tube, and a second annular gap is formed between the outer wall of the swirl inner cylinder and the inner wall of the housing ; The swirl component is arranged between the lower end of the built-in guide tube and the swirl inner tube. The gasification furnace of the invention is used for coal hydrogenation gasification reaction.

Description

technical field [0001] The invention relates to the technical field of coal gasification equipment, in particular to a gasification furnace. Background technique [0002] At present, one of the more commonly used technologies in coal gasification technology is coal hydrogenation gasification, and coal hydrogenation gasification is usually figure 1 shown in the gasifier, see figure 1 , the gasifier includes a shell 01, the top wall of the shell 01 is provided with a raw material inlet 02, the side wall of the shell 01 is provided with an exhaust port 03, and the bottom wall of the shell 01 is provided with a coke discharge port 04, The casing 01 is provided with a built-in guide tube 05, one end of the built-in guide tube 05 communicates with the raw material inlet 02, and the other end extends downward. In this way, coal and gasification agent enter the built-in guide tube 05 from the raw material inlet 02, and coal hydrogenation gasification reaction occurs in the built-i...

AI Technical Summary

Problems solved by technology

However, since the coal used in the coal hydrogasification reaction is coal powder, the semi-coke particles produced by the gasification reaction have a small particle size and good followability, and are easily entrained by the synthesis gas into the subsequent system. There are more semi-coke particles discharged from the gasifier, which increases the burden on the subsequent gas-solid separation device
