Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a novel microchannel reactor. Background Art

[0002] A microchannel reactor is a microscale chemical reactor, whose size is usually in the range of micrometers to millimeters. Compared with traditional macro reactors, microchannel reactors have a higher surface area / volume ratio, a shorter mass transfer path and a faster heat and mass transfer rate. Microchannel reactors are usually composed of a series of microchannels and microstructures to control the velocity and distribution of reactant flow to achieve higher reaction rates and selectivity. Through miniaturization of reactors, the rate of chemical reactions can be increased and the use of hazardous substances can be reduced, thereby reducing waste generation and environmental pollution. Microchannel reactors have a wide range of applications in many fields, including organic synthesis, catalytic reactions, biochemical reactions, etc. They can be used to synthesize drugs, fine chemicals and special materials, as well as to study rapid reactions and high temperature and high pressure reactions, especially in the synthesis of high value-added products such as battery-grade potassium carbonate and lithium hydroxide from salt lake and oilfield brine. In general, microchannel reactors are an advanced chemical reactor technology with great potential to have an important impact in the fields of chemical engineering, materials science, new energy and drug development.

[0003] In the process of extracting lithium from salt lake brine and oil field brine, microchannel reactor is used as a process intensification device, and is often combined with extractants to be used as a reaction device for extracting lithium, boron, rubidium, cesium and other elements from brine, or as a reaction device for generating battery-grade lithium carbonate and other lithium salt products.

Furthermore, a supporting leg 11 is fixedly arranged at the bottom of the bottom plate 1. Specifically, four groups of the supporting legs 11 are symmetrically arranged.

[0055] Two groups of feed ports 21 are provided through one side of the reactor main board 2. A mounting shell 22 is fixedly provided at one end of the feed port 21. A filter plate 221 is fixedly provided inside the mounting shell 22.

[0056] A plurality of through holes 2211 are arranged in an array on the filter plate 221, and a rotating column 222 is also provided on the filter plate 221. Specifically, a first bearing 223 is provided in the middle portion of the filter plate 221, and the rotating column 222 is arranged on the inner wall of the first bearing 223. A rotating rod 224 is provided on the outer surface of the rotating column 222. Specifically, the rotating rod 224 is symmetrically arranged on the outer surface of the rotating column 222, and the rotating rod 224 can be four groups. Further, a fan blade 225 is provided at one end of the rotating column 222.

[0057] In this embodiment, a reaction channel 23 is provided in the reactor main board 2, one end of the reaction channel 23 is connected to the feed port 21, and a discharge port 24 is provided on the other side of the reactor main board 2, and the discharge port 24 is connected to the other end of the reaction channel 23.

[0058] When the novel microchannel reactor provided in this embodiment is used, the mounting shell 22 is through-set on one of the feed ports 21. The feed port 21 is used to transmit materials such as reaction salt lake brine or oil field brine. The filter plate 221 can be used to provide the first bearing 223 and the rotating column 222 for installation. The first bearing 223 is a waterproof bearing that provides a smooth rotation of the rotating column. One side of the rotating rod 224 is in contact with the filter plate 221. When the material enters the mounting shell 22 through the feed port 21, the liquid material first contacts the fan blade 225, and the fan is driven by the flow of the material. The blades 225 rotate, and the rotating column 222 drives the rotating rod 224 to rotate. Then, the liquid material is transmitted into the reaction channel 23 through the through hole 2211. The through hole 2211 can filter the mixed particle blocks in the blocking material. Then, the rotating rod 224 rotates to stir and crush the blocking particle blocks. The crushed particle materials will not be able to block the reaction channel, which effectively solves the problem that block crystals exist in salt lake brine or oil field brine, which easily block the microchannel, making the microchannel reactor unable to be used continuously and reducing production efficiency.

[0059] In this embodiment, the bottom plate 1 and the support legs 11 are used to stably install the reactor main board 2. The fixing screw 31 is provided for the stable installation of the cover plate 3 and the reactor main board 2. The reaction channel 23 is used to mix the materials to be reacted, and the discharge port 24 can discharge the reacted materials.

[0060] Furthermore, in the novel microchannel reactor described in the embodiment of the present invention, a hinge 25 is provided on the back of the reactor main board 2, and one side of the hinge 25 is connected to the cover plate 3. A fixing block 32 is fixedly provided on one side of the cover plate 3, and a directional buckle 33 is fixedly provided on the bottom of the fixing block 32. A second bearing 12 is embedded on one side of the bottom plate 1, and a connecting column 13 is provided on the inner wall of the second bearing 12, and a mounting seat 14 is fixedly provided on one end of the connecting column 13, and a telescopic rod 15 is provided on the mounting seat 14, and the telescopic end of the telescopic rod 15 is fixedly connected to the directional buckle 33.

[0061] When the inside of the novel microchannel reactor is cleaned, the second bearing 12 can provide a rotation effect of the connecting column 13 and the mounting seat 14, and the hinge 25 is used to open and close the reactor main board 2 and the cover plate 3. The output end of the telescopic rod 15 is fixedly connected to the directional buckle 33, so that the telescopic rod 15 can support the cover plate 3. The telescopic operation of the telescopic rod 15 pushes the cover plate 3 upward to form an opening and closing. The active cooperation between the second bearing 12 and the directional buckle 33 can avoid the problem of the cover plate 3 tilting and being unable to stably support when opening and closing. After that, the inside of the reactor main board 2 can be cleaned, which solves the problem that most existing microchannel reactors are difficult to disassemble and install during cleaning.

[0062] In summary, the novel microchannel reactor provided by the embodiment of the utility model is provided with a mounting shell 22. When the novel microchannel reactor is used, the mounting shell 22 is through-set on one of the feed ports 21. The feed port 21 is used to transmit materials such as reaction salt lake brine or oil field brine. The filter plate 221 can be used to provide a first bearing 223 and a rotating column 222 for installation. The first bearing 223 is a waterproof bearing that provides a smooth rotation of the rotating column. One side of the rotating rod 224 contacts the filter plate 221. When the material enters the mounting shell 22 through the feed port 21, the liquid material first contacts the fan blade 22. 5. The fan blade 225 will be driven to rotate by the material flow, and the rotating column 222 will drive the rotating rod 224 to rotate. Then, the liquid material will be transmitted into the reaction channel 23 through the through hole 2211. The through hole 2211 can filter the mixed particle blocks in the blocking material. Then, the blocking particle blocks will be stirred and crushed by the rotation of the rotating rod 224. The crushed particle materials will not be able to block the reaction channel 23, which effectively solves the problem that block crystals exist in salt lake brine or oil field brine, which easily block the microchannel, making the microchannel reactor unable to be used continuously and reducing production efficiency.

[0063] The novel microchannel reactor provided by the embodiment of the utility model is also provided with a directional buckle 33. When the inside of the novel microchannel reactor is cleaned, the second bearing can provide a rotation effect of the connecting column and the mounting seat. The hinge is used to open and close the reactor main board and the cover plate. The output end of the telescopic rod 15 is fixedly connected to the directional buckle 33, so that the telescopic rod 15 can form a supporting effect on the cover plate 3. The telescopic operation of the telescopic rod 15 will push the cover plate 3 upward to form an opening and closing. The active cooperation between the second bearing 12 and the directional buckle 33 can avoid the problem of the cover plate 3 tilting and being unable to stably support when opening and closing. After that, the inside of the reactor main board 2 can be cleaned, which solves the problem that most existing microchannel reactors are difficult to disassemble and install during cleaning.
