Two support blocks 3 are fixedly connected to the upper front side of the base 1. A limit opening 4 is formed in the top of the support block 3. A support plate 5 is movably connected to the top of the support block 3. The same tubular microchannel reactor main body 6 is fixedly connected to the front sides of the two support plates 5. A limit block 11 is fixedly connected to the bottom of the support plate 5. The bottom of the limit block 11 penetrates through the limit opening 4 and extends to the outside of the limit opening 4. The limit block 11 is movably clamped with the limit opening 4. A positioning mechanism 12 is arranged on the support plate 5.

[0032] Specifically, a liquid inlet 7 is arranged on the upper right side of the top of the tubular microchannel reactor main body 6. A liquid outlet 8 is arranged on the lower left side of the bottom of the tubular microchannel reactor main body 6. A heat exchange medium inlet 9 is arranged on the left side of the tubular microchannel reactor main body 6. A heat exchange medium outlet 10 is arranged on the right side of the tubular microchannel reactor main body 6.

[0033] When specifically implemented, the positioning mechanism 12 includes a fixing plate 121, a screw 122, a mounting block 123, a card slot 124, a handle 125, a bearing 126, a connecting plate 127, a guide rod 128, and a clamping block 129. The fixing plate 121 is fixedly connected to the top of the support plate 5.

[0034] Specifically, the screw 122 is threadedly connected to the inside of the fixing plate 121. Both the left and right ends of the screw 122 penetrate through the fixing plate 121 and extend to the outside of the fixing plate 121.

[0035] When specifically implemented, a mounting block 123 is fixedly connected to the front side of the vertical plate 2 and at a position between the two fixing plates 121.
