Description

Technical Field

[0001] This utility model relates to the field of microchannel reactor technology, specifically to an anti-clogging microchannel reactor. Background Technology

[0002] A microchannel reactor is a three-dimensional structural element that can be used to carry out chemical reactions, manufactured on a solid matrix using special microfabrication techniques. Microchannel reactors typically have channels of small size and diverse shapes, in which fluids flow and the desired reactions occur. Microreactors have excellent heat and mass transfer capabilities, enabling instantaneous and uniform mixing and heat exchange of materials. Therefore, many reactions that cannot be achieved in conventional reactors can be realized in microreactors.

[0003] In the operation of existing microchannel reactors, if a large amount of solids are produced during the reaction, the micro-reaction channels are easily blocked. This can reduce the utilization rate of raw materials or even cause production to be interrupted. The inlet pipe of the microchannel reactor lacks the function of filtering impurities, so impurities are easily transported to the microchannels of the reactor and cause blockage. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging microchannel reactor. The first and second filter screens are arranged in a staggered manner through a chute, and the slider slides in the chute to form a gradient filtration. The first filter screen intercepts large particles, and the second filter screen intercepts fine impurities to avoid clogging. The spiral guide vane fixed by the T-shaped rod enhances the fluid mixing efficiency and prevents particle deposition, thus reducing the risk of clogging.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is an anti-clogging microchannel reactor, including a reactor body with a curved tube inside, an inlet pipe and an outlet pipe connected to the reactor body, a filter assembly connected to the inlet pipe, a first mounting cylinder and a second mounting cylinder respectively on both sides of the curved tube, and a backflushing assembly installed between the first mounting cylinder and the second mounting cylinder.

[0007] The filter assembly includes a first threaded cylinder with a groove on its inner wall, on which a first filter screen and a second filter screen slide together.

[0008] The recoil assembly includes a T-shaped rod that fits between the first mounting cylinder and the second mounting cylinder. A spiral guide vane is provided on the T-shaped rod and is located inside the curved tube.

[0009] Furthermore, both the first filter screen and the sidewall of the slider are equipped with sliders, which slide inside the groove.

[0010] Furthermore, the chute lengths are different, and the first filter screen and the slider are set one behind the other on the same horizontal line.

[0011] Furthermore, the filter assembly also includes a first connecting cylinder and a second connecting cylinder, which are threaded together, with the first threaded cylinder threaded inside the second connecting cylinder.

[0012] Furthermore, a second threaded cylinder is provided on one side of the first connecting cylinder, and a water pipe is connected to the other side of the first connecting cylinder. A threaded groove is opened inside one side of the second connecting cylinder, and the second threaded cylinder is threadedly engaged with the threaded groove.

[0013] Furthermore, a second bearing is installed on the T-shaped rod, and a third mounting sleeve is installed on the inner ring of the second bearing. The third mounting sleeve is threaded into the first mounting sleeve.

[0014] Furthermore, a locking block is installed at one end of the T-shaped rod. The locking block fits inside the second mounting cylinder. The first bearing is installed inside the second mounting cylinder. A cylinder is installed on the inner ring of the first bearing. A locking groove is opened on the inner wall of the cylinder, and the locking groove fits into the locking block.

[0015] This utility model has the following beneficial effects:

[0016] This utility model has a filter assembly installed on the feed pipe. The first and second connecting cylinders of the filter assembly can be quickly disassembled through threaded connection, which is convenient for cleaning or replacing the filter screen. The first and second filter screens are arranged in a staggered manner through the sliding groove to form a gradient filtration. The first filter screen intercepts large particles, and the second filter screen intercepts fine impurities to avoid clogging.

[0017] This invention installs a backflushing assembly inside a curved pipe, which generates turbulence under the disturbance of the spiral guide vanes. The spiral guide vanes, fixed by a T-shaped rod, enhance fluid mixing efficiency and prevent particle deposition. The curvature design of the curved pipe reduces dead angles. Combined with the dynamic flushing effect of the spiral guide vanes, the risk of blockage is reduced. The third mounting cylinder is threadedly connected to the first mounting cylinder, which facilitates the overall disassembly of the backflushing assembly for deep cleaning.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

By precisely controlling the reaction conditions, an efficient, safe, and continuous production process can be achieved. A feed pipe 2 and a discharge pipe 3 are respectively connected on the reactor body 1. A filter assembly 4 is connected to the feed pipe 2. A first mounting cylinder 8 and a second mounting cylinder 801 are respectively arranged on both sides of the curved tube 7. A backflushing assembly 9 is installed between the first mounting cylinder 8 and the second mounting cylinder 801.

[0028] The filter assembly 4 includes a first threaded cylinder 401, a first connecting cylinder 5 and a second connecting cylinder 6. The first connecting cylinder 5 and the second connecting cylinder 6 are threaded together. The second threaded cylinder 501 is provided on one side of the first connecting cylinder 5, and the other side of the first connecting cylinder 5 is connected to a water pipe 502. A threaded groove 601 is opened inside one side of the second connecting cylinder 6. The second threaded cylinder 501 is threadedly engaged with the threaded groove 601. The first connecting cylinder 5 and the second connecting cylinder 6 can be quickly disassembled through the threaded engagement, which is convenient for cleaning or replacing the filter screen.

[0029] The first threaded cylinder 401 is threaded into the second connecting cylinder 6. A groove 402 is formed on the inner wall of the first threaded cylinder 401. A first filter screen 403 and a second filter screen 404 slide on the groove 402. A slider 405 is provided on the side wall of both the first filter screen 403 and the slider 405. The slider 405 slides inside the groove 402. The groove 402 has different lengths. The first filter screen 403 and the slider 405 are arranged one after the other on the same horizontal line. The first filter screen 403 and the second filter screen 404 are arranged in a staggered manner through the groove 402. The slider 405 slides in the groove 402 to form a gradient filtration. The first filter screen 403 intercepts large particles, and the second filter screen 404 intercepts fine impurities to avoid clogging.

[0030] The backflushing assembly 9 includes a T-shaped rod 901, which fits between the first mounting cylinder 8 and the second mounting cylinder 801. A spiral guide vane 902 is provided on the T-shaped rod 901 and is located inside the curved tube 7. Turbulence is formed under the disturbance of the spiral guide vane 902. The spiral guide vane 902, fixed by the T-shaped rod 901, enhances the fluid mixing efficiency and prevents particle deposition. The composite structure of the spiral guide vane 902 and the curved tube 7 extends the reaction path and improves the reaction uniformity. The curvature design of the curved tube 7 reduces dead angles. Combined with the dynamic flushing effect of the spiral guide vane 902, the risk of blockage is reduced.

[0031] A second bearing 903 is installed on the T-shaped rod 901. A third mounting cylinder 904 is installed on the inner ring of the second bearing 903.

A cylinder 803 is installed on the inner ring of the first bearing 802. A groove 804 is opened on the inner wall of the cylinder 803. The groove 804 cooperates with the locking block 905. The cooperation between the locking block 905 and the groove 804 ensures the stable rotation of the T-shaped rod. The first bearing 802 and the second bearing 903 reduce friction. The third mounting cylinder 904 is threaded into the first mounting cylinder 8, which facilitates the overall disassembly of the backflushing assembly for deep cleaning.

[0032] When using a microchannel reactor, the reactants enter the reactor body 1 through the feed pipe 2. They are first filtered by the first filter screen 403 and the second filter screen 404 of the filter assembly 4. The water inlet pipe 502 can be connected to the cleaning liquid to backwash the filter screens. The filtered material enters the curved pipe 7. When the pressure difference increases and local blockage occurs, the spiral guide vane 902 is rotated at high speed by rotating the T-shaped rod 901. Centrifugal force is used to peel off the adhering substances. The reaction product flows out through the discharge pipe 3, which is also equipped with the filter assembly 4 to ensure the purity of the product.
