[0002] A microchannel reactor is a microscale chemical reactor, typically ranging in size from micrometers to millimeters. Compared to traditional macroscopic reactors, microchannel reactors have a higher surface area to volume ratio, shorter mass transfer paths, and faster thermal-mass transfer rates. Microchannel reactors are usually composed of a series of microchannels and microstructures used to control the speed and distribution of reactant flow to achieve higher reaction rates and selectivity. By miniaturizing reactors, the rate of chemical reactions can be increased and the amount of hazardous substances used can be reduced, thereby reducing waste generation and environmental pollution.

[0003] Currently, in use, the experimental liquid in the reaction channel of a microreactor tends to adhere to the inner wall of the reaction channel during the reaction. Microchannel reactors are not easy to disassemble, making it difficult to clean the reaction channel. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a microchannel reactor experimental device. Through the liquid injection mechanism, the experimental liquid is added into the reaction channel inside the shell from the inlet. The serpentine reaction channel can effectively improve the reaction time of the experimental liquid and meet the reaction requirements. During the experiment, high-temperature liquid can be injected into the flow channel between the shells through the liquid inlet pipe so that the high-temperature liquid can heat the experimental liquid in the reaction channel. Conversely, the liquid inlet pipe can also inject cooling liquid into the flow channel to cool the experimental liquid, thereby effectively improving the experimental effect of the reactor.

[0013] 2. This utility model provides a microchannel reactor experimental device.

The insertion cylinder is moved so that it can penetrate the round hole, and the bottom end of the limiting cylinder contacts the upper side of the fixing plate. At this time, the insertion cylinder is inserted into the round hole, preventing the upright from tilting backward.

[0016] The present invention will be further described in detail below with reference to embodiments: like Figures 1-5As shown, this utility model provides a microchannel reactor experimental device, including a lower shell 1, an upper shell 2 movably mounted on the upper end of the lower shell 1, a liquid injection mechanism 3 between the lower shell 1 and the upper shell 2, and mounting mechanisms 4 symmetrically mounted on the outer sides of both ends of the lower shell 1 and the upper shell 2. A lower reaction channel 5 is opened on the upper surface of the lower shell 1, and an upper reaction channel 7 is opened on the lower surface of the upper shell 2.

[0017] Both the lower shell 1 and the upper shell 2 have flow channel inlets 6 on their left sides and flow channel outlets 8 on their right sides, with the lower reaction flow channel 5 and the upper reaction flow channel 7 corresponding to each other.

[0018] The lower reaction channel 5 and the upper reaction channel 7 are connected to the channel inlet 6 and the channel outlet 8.

[0019] In this design, the inlet 6 facilitates the entry of the experimental liquid into the reaction channel inside the shell, while the outlet 8 facilitates the discharge of the experimental liquid from the reaction channel.

[0020] like Figures 2-3 As shown, the liquid injection mechanism 3 includes a lower liquid flow channel 31, which is opened on one side of the upper surface of the lower housing 1. The lower housing 1 has an inlet pipe 32 and a drain pipe 33 fixed on one side of each end. The upper surface of the upper housing 2 has a sealing groove 34, and the lower surface of the upper housing 2 has an upper liquid flow channel 35. The lower surface of the upper housing 2 has a sealing block 36 fixed on the outer side of the lower surface.

[0021] Both the inlet pipe 32 and the outlet pipe 33 are connected to the lower liquid flow channel 31. The lower liquid flow channel 31 and the upper liquid flow channel 35 are respectively located inside the lower reaction channel 5 and the upper reaction channel 7.

[0022] The lower liquid flow channel 31 and the upper liquid flow channel 35 correspond to each other and fit together movably to facilitate liquid flow. The sealing block 36 and the sealing groove 34 are fitted together and can be movably installed.

[0023] In this design, the sealing effect between the lower shell 1 and the upper shell 2 can be effectively improved by sealing the sealing block 36 and sealing groove 34. The liquid inlet pipe 32 facilitates the entry of high temperature liquid or cooling liquid into the liquid flow channel inside the shell, which is convenient for heating or cooling the experimental liquid in the reaction channel. The liquid outlet pipe 33 facilitates the discharge of liquid.

[0024] like Figures 4-5As shown, the installation mechanism 4 includes a base frame 41. The bottom end of the base frame 41 is symmetrically and fixedly connected to the outer walls of both ends of the lower housing 1. A rotating rod 42 is rotatably installed on the inner side of the base frame 41. A sleeve 43 is fixedly sleeved on the outside of the rotating rod 42. A vertical rod 44 is fixedly connected to the upper side of the sleeve 43. Fixed plates 45 are symmetrically and fixedly connected to the outer walls of both ends of the upper housing 2. A circular hole 46 is opened through the middle of the fixed plate 45. A through groove 47 is opened on the front side of the fixed plate 45. A threaded part 48 is opened on the top outer wall of the vertical rod 44. A top plate 49 is fixedly connected to the top of the vertical rod 44. An insert 410 is slidably sleeved on the upper end of the vertical rod 44. A limit cylinder 411 is fixedly connected to the upper side of the insert 410. A handle 412 is fixedly installed on the upper side of the limit cylinder 411.

[0025] The through groove 47 is connected to the round hole 46, and the outside of the upright 44 can pass through the through groove 47 and be placed inside the round hole 46. The upright 44 and the round hole 46 are movably installed together.

[0026] The middle parts of the limiting cylinder 411 and the handle 412 are slidably installed through the outer wall of the upright 44. The inner wall of the limiting cylinder 411 is threadedly installed with the threaded part 48. The insert 410 is matched with the round hole 46 and is movably installed.

[0027] In this design, the limiting cylinder 411 is threadedly installed with the threaded part 48, which facilitates the upper and lower limit movement of the insert 410, the limiting cylinder 411 and the handle 412 on the threaded part 48 of the upright 44. Because the lower housing 1 and the upper housing 2 can be quickly disassembled, the staff can directly access the reaction channel to thoroughly clean the dirt, impurities and other contaminants inside.

[0028] The working principle of this microchannel reactor experimental device will be explained in detail below.

[0029] like Figures 1-5As shown, in use, the microchannel reactor experimental device introduces the experimental liquid into the reaction channel inside the shell through the inlet 6. The serpentine reaction channel effectively increases the reaction time of the experimental liquid, meeting the reaction requirements. During the experiment, high-temperature liquid can be injected into the flow channel between the shells through the inlet pipe 32, so that the high-temperature liquid can heat the experimental liquid in the reaction channel. Conversely, the inlet pipe 32 can also inject cooling liquid into the flow channel to cool the experimental liquid, thereby effectively improving the experimental effect of the reactor. When the upper shell 2 and the lower shell 1 are installed, their opposite surfaces are spliced ​​together, so that the sealing block 36 on the lower side of the upper shell 2 can be fitted into the sealing groove 34 on the upper side of the lower shell 1, thereby effectively improving the sealing performance after the shell is installed. Then, by rotating the upright rod 44, the top of the upright rod 44 passes through the through groove 47. The knob is turned downwards to rotate the limiting cylinder 411 and the insert cylinder 410. The limiting cylinder 411 and the threaded part 48 on the top outer wall of the upright 44 are threaded together to facilitate downward movement. The insert cylinder 410 can then pass through the round hole 46. The bottom end of the limiting cylinder 411 contacts the upper side of the fixing plate 45. At this time, the insert cylinder 410 is inserted into the round hole 46 to prevent the upright 44 from tilting backwards. Under the pressure of the limiting cylinder 411, the fixing plate 45 is limited, thus effectively and quickly fixing the upper shell 2 onto the lower shell 1. This fixing operation is simple and convenient. Conversely, when disassembling, the knob 412 is turned upwards to separate the limiting cylinder 411 from the upper side of the fixing plate 45. At the same time, the insert cylinder 410 is screwed out from the round hole 46, and the upright 44 can be rotated backwards to separate it from the round hole 46, thus facilitating the disassembly of the upper shell 2 and the cleaning of the reaction channel.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
