Abstract

The invention discloses a gasifier and relates to the technical field of coal gasification equipment, which is invented for solving the problems that the content of carbocoal particles in synthesis gas exhausted from an existing gasifier is greater, and the burden of subsequent gas-solid separation is heavier. The gasifier comprises a casing, wherein a raw material inlet is formed in the top wall of the casing; an exhaust opening is formed in the side wall of the casing; a coke discharging opening is formed in the bottom wall of the casing; a built-in guide cylinder, a rotational flow inner cylinder and a rotational flow member are arranged in the casing; one end of the built-in guide cylinder is communicated with the raw material inlet, and the other end of the built-in guide cylinder downwards extends; the rotational flow inner cylinder is arranged at the outer part of the lower end of the built-in guide cylinder in a sleeving manner; in addition, the upper end of the rotational flow inner cylinder upwards extends to a position close to the exhaust opening; a first annular space is formed between one circumference of the inner wall of the rotational flow inner cylinder and the built-in guide cylinder; a second annular space is formed between one circumference of the outer wall of the rotational flow inner cylinder and the inner wall of the casing; the rotational flow member is arranged between the lower end of the built-in guide cylinder and the rotational flow inner cylinder. The gasifier disclosed by the invention is used for coal hydrogasification 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...
