Solid-gas microchannel reactor

Abstract

The invention discloses a solid-gas microchannel reactor. The solid-gas microchannel reactor comprises a casing detachably connected with a microchannel for conveying a gas; a reaction tube traversingthrough the casing and provided with a plurality of ventilation openings; a catalysis structure arranged on the reaction tube and comprising a solid phase drug; a plurality of drainage structures forguiding the gas to move from the middle part of the reaction tube towards the catalysis structure, contact with the inner wall of the casing and afresh traverse through the catalysis structure spirally; and a filtering structure cooperating with the casing to filter the gas not entering the reaction tube in order to remove solid impurities contained in the gas. The drainage structures are arranged, so the gas can traverse through the catalysis structure through the drainage structures in order to carry out a catalysis reaction, thereby it is ensured that the whole gas can be effectively catalytically activated, the gas activation energy is improved, the subsequent reaction efficiency is accelerated, the reaction time is shortened, and the gas treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical production, in particular to a solid-gas microchannel reactor. Background technique [0002] The solid-gas microchannel reactor is a continuous operation reactor with a tubular shape and a large length-to-diameter ratio. Such reactors can be very long, for example, reactor tubes for propylene dimerization can be measured in kilometers. The structure of the reactor can be a single tube or a multi-tube parallel connection; it can be an empty tube, such as a tube cracking furnace, or a filled tube filled with granular catalysts in the tube for heterogeneous catalytic reactions, such as a column tube Fixed-bed reactor; solid-gas microchannel reactor is suitable for both liquid phase reaction and gas phase reaction. [0003] In the existing solid-gas microchannel reactor, an inner tube with a catalyst is pierced on a straight sleeve, and then the gas to be reacted is passed into the sleeve, and the ...

AI Technical Summary

Problems solved by technology

[0003] In the existing solid-gas microchannel reactor, an inner tube with a catalyst is pierced on a straight sleeve, and then the gas to be reacted is introduced into the sleeve, and the gas will be catalyzed and activated through the inner tube and then flow out from the sleeve. The other end of the tube flows out. During the process of gas catalysis, there may be solid impurities in the gas. If the solid impurities directly enter the microchannel reactor, the solid impurities are easy to accumulate on the surface of the catalyst, which will affect the gas and gas. The contact between the microchannel reactors affects the catalytic efficiency, and because the structure of the microchannel reactor is more complex than the ordinary microchannel, if the solid impurities directly enter the microchannel reactor, the solid impurities will Accumulated in the microchannel reactor, causing the interior of the microchannel reactor to become dirty and difficult to clean
