Description

A kind of micro passage reaction

Technical field

The utility model belongs to chemical production technical field, more particularly, to a kind of micro passage reaction.

Background technique

Micro passage reaction be it is a kind of in a tubular form, the very big continuous manipulation reactor of draw ratio.This reactor can be very It is long, if the reactor pipe range of propylene dimerization is in terms of kilometer.The structure of reactor can be single tube, be also possible to multitube parallel；It can To be blank pipe, such as tube cracking furnace is also possible to the filling pipe of the filler particles shape catalyst in pipe, anti-to carry out heterogeneous catalysis It answers, such as calandria type fixed bed reactor；Micro passage reaction is not only suitable for liquid phase reactor, and is suitable for gas phase reaction.

It is that the inner tube with catalyst is equipped on straight casing to existing micro passage reaction, then to casing It is passed through gas to be reacted in the middle, then gas can be flowed out by inner tube by catalytic activation from the other end of casing, but should The micro passage reaction existing defects of mode, one are to need to connect a U-tube when being passed through reaction gas or export reaction gas As buffering microchannel, slow down the flow velocity of reaction gas, increase the time contacted between reaction gas and inner tube, but which its need U-tube is additionally set, and the volume of U-tube is larger, will lead to whole equipment volume and become larger, the space occupied is big；Second, Reaction gas is when being passed into casing, if microchannel in entire is used then to will affect gas to be similar to solid setting The amount that can be passed through causes the volume of entire reactor larger, but react effect it is poor, and if by the way of hollow, gas Body is easy largely to be gathered in close to siphunculus exit, causes gas output big, portion gas is caused not urged effectively Change activation；And gas is mostly disposably contacted with catalyst interaction during being catalyzed to gas, therefore portion Divide gas and catalyst insufficient contact, causes catalyst to the catalytic activation low efficiency of gas.

Utility model content

The utility model for overcome the deficiencies in the prior art, provides that a kind of structure is simple, microchannel of high catalytic efficiency Reactor.

To achieve the goals above, the utility model uses a kind of following technical scheme: micro passage reaction, including

Casing, for being detachably connected with the microchannel of conveying gas；

Reaction tube is arranged in described sleeve pipe and has multiple ventilation orifices；
