[0041] The reinforcement unit includes a snap-fit ​​groove 505, a stud 506, and a reinforcement plate 507;

[0042] The snap-fit ​​grooves 505 are symmetrically opened on both sides of the inner wall of the rectangular plate 503, and the studs 506 are fixed to the middle of the front end of the front cover plate 101.

[0043] The reinforcing plate 507 is sleeved on the outside of the stud 506. Both sides of the reinforcing plate 507 are engaged with the inside of the engagement groove 505 and are screwed into the stud 506 by the nut.

The heat exchange liquid inlet 104 and the heat exchange liquid outlet 105 penetrate the microporous reaction plate 107 and are connected to the liquid inlet and liquid outlet of the heat exchange channel 109, respectively.

[0046] A first sealing element 2 is provided at the contact position between the front end of the microporous reaction plate 107 and the front cover plate 101, and a third sealing element 4 is provided at the contact position between the rear end of the microporous reaction plate 107 and the rear cover plate 110.

[0047] A second sealing element 3 is sleeved on the outside of the microporous reaction plate 107. The second sealing element 3 is in contact with the rear end face of the front cover plate 101 and the front end face of the rear cover plate 110, and a through hole is provided on the second sealing element 3 for the docking post 501 to pass through.

[0048] In this embodiment, the assembly operation of the microchannel reactor 1 is as follows:

[0049] First, attach the third sealing element 4 to the rear end of the microporous reaction plate 107, and then attach it to the front end of the rear cover plate 110.

[0050] Then, the second sealing element 3 is sleeved on the outside of the microporous reaction plate 107. At the same time, the second sealing element 3 is sleeved on the outside of multiple docking posts 501 through the through hole. After that, the first sealing element 2 is attached to the front end of the microporous reaction plate 107, and then the front cover plate 101 is attached and assembled with it. During this process, the docking post 501 passes through the assembly hole 106 to the front end of the front cover plate 101. The raw material inlet 102 and the outlet 103 are respectively connected to the liquid inlet end and the liquid outlet end of the reaction channel 108. The heat exchange liquid inlet 104 and the heat exchange liquid outlet 105 pass through the microporous reaction plate 107 and are respectively connected to the liquid inlet end and the liquid outlet end of the heat exchange channel 109. (It should be noted that the first sealing element 2 has through holes for the heat exchange liquid inlet 104 and the heat exchange liquid outlet 105 to pass through. The first sealing element 2 simultaneously forms a sealing operation between the heat exchange liquid inlet 104, the heat exchange liquid outlet 105 and the microporous reaction plate 107.)

[0051] Next, take out the rectangular plate 503 and align the large diameter slot of the side convex groove 503 with the docking post 501. The rectangular plate 503 is fitted onto the outside of multiple docking posts 501 through the large diameter slot. Then, move the rectangular plate 503 horizontally so that the small diameter slot of the side convex groove 503 is engaged with the inside of the C-shaped groove 502. At this time, the connection and fixation between the rear cover plate 110 and the front cover plate 101 are completed.

[0052] Next, the reinforcing plate 507 is sleeved on the outside of the stud 506, and the two sides of the reinforcing plate 507 are engaged with the inside of the engagement groove 505. Then, the nut is screwed into the stud 506 to achieve the pressing of the reinforcing plate 507. At this time, the horizontal movement of the rectangular plate 503 is locked, thereby ensuring the stable assembly of the microchannel reactor 1.

[0053] The disassembly of the microchannel reactor 1 can be achieved by reversing the above operation. The snap-fit ​​structure composed of the docking column 501, the C-shaped slot 502, and the rectangular plate 503 replaces the bolt fastening structure of the existing microchannel reactor. Compared with the traditional bolt fastening structure, the locking structure of the stud 506 and the nut to the reinforcing plate 507 significantly reduces the tightening and loosening of the nut, which can effectively improve the disassembly and assembly efficiency of the microchannel reactor 1.

[0054] Please refer to this carefully. Figures 1-4 The reinforcement unit is provided with multiple sets along the vertical direction, and the C-shaped slots 502 on the multiple docking columns 501 are distributed in the same direction.

[0055] In this embodiment, the structure of multiple sets of reinforcement units effectively ensures the stability of the reinforcement. The multiple C-shaped slots 502 are oriented in the same direction, which facilitates the sleeve and snap-fit ​​operation of the rectangular plate 503 and the docking column 501. The number of reinforcement units is significantly less than the number of bolt fastening structures in existing microchannel reactors, which can effectively reduce the tightening and loosening of nuts and achieve the effect of improving the efficiency of disassembly and assembly.

[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
