Wherein, hot-mounting process is a kind of very well known technological means, is no longer described in detail herein.

Wherein, when mounted, using interference fit, pipe sleeve 602 between the internal diameter of the outer diameter of casing 602 and mixing tube 601 It is fixedly installed in mixing tube 601 by hot-mounting process, can either so ensure the fastness of installation, in turn ensure casing 602 With the sealing performance between mixing tube 601.

As a kind of optimal technical scheme, as shown in fig. 6, being equipped on the inner wall of left reaction chamber 504 and right reaction chamber 505 Several cavitation-preventive pits 509, cavitation-preventive pit 509 are distributed in the surface of Eight Diagrams line protrusion 506 and lozenge protrusion 507.

Structure design by doing so, when fluid is by the inner wall of left reaction chamber 504 and right reaction chamber 505, the fluid Just the liquid in cavitation-preventive pit 509 has been taken away, cavitation-preventive pit 509 is filled again by new fluid so that cavitation-preventive pit 509 positions generate eddy flow, impact of the bubble to 505 inner wall of left reaction chamber 504 and right reaction chamber in fluid are avoided, so as to subtract Lack destruction of the cavitation erosion to 505 inner wall of left reaction chamber 504 and right reaction chamber, extend the service life of microchannel reaction module 5.

Wherein, those skilled in the art can after the technical solution of the utility model is read, and select and determining cavitation-preventive The quantity of pit 509, this is the routine techniques ability that it should have, and is no longer described in detail herein.

As a kind of optimal technical scheme, the inner surface Carburization Treatment of left reaction chamber 504 and right reaction chamber 505.

By carrying out case-carbonizing processing, the impact resistance of left reaction chamber 504 and right reaction chamber 505 is not only increased, The surface anti-cavitation ability of 505 inner wall of left reaction chamber 504 and right reaction chamber is also improved, considerably increases microchannel reaction module 5 performance extends its service life.

As described above, the micro passage reaction of the utility model can not only learn reaction process in time by probe tube 7 In state, and improve reaction efficiency of the gas/liquid flow in reactor；Importantly, it can also further effectively prevent Damage of the cavitation erosion to microchannel reaction module 5, substantially prolongs the service life of micro passage reaction, this has in this field Extremely important meaning available for high efficient heat exchanging, efficiently mixes, strong exothermal reaction process, high added value fine chemicals, severe toxicity The production process of substance, ultra-fine/nano particle and high explosive has good application potential and industrial production value.

Although for the purpose illustrated and described, and describe the above embodiment of the utility model and the shown knot of attached drawing Structure and processing procedure.But it is to describe in detail that these, which are not, can not the scope of the utility model be confined to this.To this field For technical staff, numerous modifications and variations can be made to the above embodiment of the utility model, and these all modifications And/or variation is included within the claim limited range such as the utility model, without departing from such as claim institute The scope of the utility model and spirit of restriction.
