Gas distribution device used for slurry bed reactor and slurry bed reactor

Abstract

The invention discloses a gas distribution device for a slurry bed reactor and the slurry bed reactor. The gas distribution device includes: an air inlet pipe, the air inlet pipe has an air inlet and an air outlet; a uniform distribution piece, the uniform distribution piece is arranged on the air intake pipe, and a gas passage is arranged in the uniform distribution piece, the gas passage communicates with the air outlet, and the gas passage The bottom wall is provided with a plurality of uniform air holes, and the plurality of uniform air holes are distributed around the circumference of the inlet pipe at intervals; the spoiler, the spoiler includes a plurality of air injection pipes located in the kettle body, and each air injection pipe has an air injection pipe with an opening facing downward. Mouth, each air injection port is positioned at the below of the uniform air hole, and each air injection pipe communicates with the part outside the kettle body of the air inlet pipe through the connecting pipeline extending out of the still body. According to the gas distribution device of the present invention, the uniform distribution of the gas in the still body can be realized under relatively low pressure drop, and the problem of the deposition of solid particles in the still body can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of slurry bed reactors, in particular to a gas distribution device for the slurry bed reactor and the slurry bed reactor. Background technique [0002] The slurry bed reactor is an important gas-liquid-solid multiphase reaction device, especially suitable for heterogeneous catalytic reactions such as acetylene hydrogenation to ethylene and Fischer-Tropsch synthesis. Generally, the slurry bed reactor has disadvantages such as uneven gas distribution and solid particle deposition, which affect the effect of material reaction in the reactor body of the slurry bed reactor, and in severe cases, it will cause production failure and shutdown. [0003] Although some slurry bed reactors solve the problem of uniform gas distribution in the kettle, they fail to solve the problem of solid particle deposition, and the slurry bed reactor has a large pressure loss and high energy consumption. Although other slurry bed rea...

Generally, the slurry bed reactor has disadvantages such as uneven gas distribution and solid particle deposition, which affect the effect of material reaction in the reactor body of the slurry bed reactor, and in serious cases, it will cause production failure and shutdown

[0003] Although some slurry bed reactors solve the problem of uniform gas distribution in the kettle body, they fail to solve the problem of solid particle deposition, and the pressure loss of the slurry bed reactor is relatively large, and the energy consumption is relatively high

Although other slurry bed reactors can solve the problem of solid particle deposition, the effect of gas uniform distribution is poor
