Description

Technical Field

[0001] The invention relates to the technical field of gas adsorption, and in particular to a gas molecule adsorption device and an assembly method thereof. Background Art

[0002] When the pulse gas laser is working continuously at the repetition frequency, the working gas in its closed working chamber needs to circulate. For some gas lasers, such as discharge-induced non-chain pulsed HF / DF lasers, the HF / DF excited-state gas molecules generated by the discharge-induced gas reaction will have a strong de-excitation effect on the excited-state molecules when they transition to ground-state gas molecules after the laser is generated, which will significantly reduce the power of the continuously working laser. If no measures are taken, the laser power will usually drop by more than 80% of the initial power after emitting 1,000 pulses, which will seriously affect the application of such lasers. Summary of the invention

[0008] Furthermore, the liquid core is a rectangular parallelepiped, the liquid channel is arranged inside the rectangular parallelepiped and penetrates through the liquid channel, and the cross section of the liquid channel is rectangular or circular.

[0009] Furthermore, the seal is a rectangular parallelepiped, and the outer end surface of the seal is flush with the outer end surface of the liquid-permeable core.

[0010] Furthermore, the opening of the anti-leakage net is smaller than the diameter of the molecular sieve particles.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] like Figure 1-Figure 4 As shown, a gas molecule adsorption device provided by an embodiment of the present invention includes: a fixed frame 1, at least two liquid-permeable cores 2, at least one adsorption core 3 and molecular sieve particles 5. The liquid-permeable cores 2 and the adsorption cores 3 are alternately arranged in the fixed frame 1, and the first layer and the last layer are both liquid-permeable cores 2. The molecular sieve particles 5 are arranged in the adsorption core 3. The liquid flow direction of the liquid-permeable core 2 is perpendicular to the gas flow direction of the adsorption core 3. The molecular sieve particles are aluminosilicate materials, usually in the shape of spherical particles, with many pores in the structure, which can adsorb molecules smaller than the pore diameter inside the pore, and exclude molecules larger than the pore, thereby screening molecules.

[0043] The fixed frame 1 includes a first fixed plate 11, a second fixed plate 12, a first fixed frame 13 and a second fixed frame 14. The first fixed frame 13 and the second fixed frame 14 are respectively arranged on both sides of the gas inlet and outlet of the adsorption core 3. The first fixed plate 11 and the second fixed plate 12 are respectively arranged at the top and bottom of the first fixed frame 13 and the second fixed frame 14; the first fixed frame 13 and the second fixed frame 14 have the same structure and are both hollow rectangular frames.

[0044] Anti-leakage nets 4 are also provided on the first fixed frame 13 and the second fixed frame 14 facing the gas inlet and outlet of the adsorption core 3 respectively to prevent leakage of molecular sieve particles 5 or other impurities; seals 6 are also provided on both sides of the adsorption core 3 perpendicular to the gas flow direction, and the seals 6 are connected to the fixed frame 1.

[0045] The first fixing frame 13 and the second fixing frame 14 press the anti-leakage net 4 by screws and are connected with the first fixing plate 11, the second fixing plate 12 and the sealing strip 6. The mesh opening of the anti-leakage net 4 is smaller than the diameter of the molecular sieve particles 5.

[0046] Liquid side sealing heads 7 are also provided on both sides of the water inlet and outlet of the liquid core 2. The liquid side sealing heads 7 are connected to the fixed frame 1, the liquid core 2 and the sealing strip 6, and the liquid side sealing heads 7 are provided with liquid holes 71 connected to the liquid pipeline, so as to be connected to the liquid pipeline, thereby realizing liquid supply or liquid discharge to the liquid core 2. The temperature of the adsorption core 3 is lowered or raised by circulating liquids of different temperatures; in this embodiment, the liquid side sealing heads 7 are rectangular troughs.

[0047] In this implementation, if Figure 5-Figure 8 As shown, the arrangement of four liquid-permeable cores 2 and three adsorption cores 3 is taken as an example; the arrangement order of the four liquid-permeable cores 2 and the three adsorption cores 3 in the fixed frame 1 is from bottom to top: a liquid-permeable core 2 is placed in the first layer, and then the adsorption cores 3 and the liquid-permeable cores 2 are arranged alternately, and another liquid-permeable core 2 is placed in the last layer to ensure that the first and last layers are both liquid-permeable cores 2. Seals 6 are also provided on both sides of the adsorption core 3 perpendicular to the gas flow direction. The seals are rectangular parallelepiped, and the outer end faces of the seals are flush with the outer end faces of the liquid-permeable cores 2.

[0048] Thus, the temperature of the adsorption core is lowered or increased by circulating liquids of different temperatures through the liquid core, thereby achieving online efficient real-time adsorption of gas molecules and online desorption regeneration of the molecular sieve.

[0049] The liquid core 2 is provided with at least one liquid channel 21, which lowers or raises the temperature of the adsorption core by circulating liquids of different temperatures; in this embodiment, there are multiple liquid channels 21, and the liquid core 2 is made of a metal heat-conducting material such as aluminum alloy or copper. The liquid core 2 can be processed by cutting or welding, and the manufacturing method is not limited in the present invention, as long as the design requirements are met.

[0050] In this embodiment, the liquid core 2 is a rectangular parallelepiped, the liquid channel 21 is located inside the rectangular parallelepiped and is arranged through the liquid channel 21, and the cross section of the liquid channel 21 is rectangular or circular.

[0051] The adsorption core 3 is provided with at least one gas channel 31 containing molecular sieve particles 5. In each gas channel 31, at least one molecular sieve particle 5 is provided in a direction perpendicular to the gas flow direction and in the same direction as the gas flow direction. In this embodiment, only one molecular sieve particle 5 is provided in the direction perpendicular to the gas flow direction, and multiple molecular sieve particles 5 are provided in the same direction as the gas flow direction. In other embodiments, at least two molecular sieve particles 5 are provided in the direction perpendicular to the gas flow direction.

[0052] Below the gas channel 31 , the adsorption core 3 and the liquid core 2 together form a chip groove 32 for collecting the powder chips falling off the molecular sieve particles 5 .

[0053] The outer contour of the adsorption core 3 is a cuboid, and is made of a metal heat-conducting material, such as aluminum alloy or copper. The adsorption core 3 can be processed by cutting or welding, and the manufacturing method is not limited in the present invention, as long as the design requirements are met.

[0054] The adsorption core 3 includes at least one structure with an H-shaped cross section, and the gas channel 31 is the upper half of the H-shape; the molecular sieve particles 5 are placed on the crossbeam of the H-shaped structure, and a chip hole 33 is provided on the crossbeam. The size of the chip hole 33 is smaller than the size of the molecular sieve particles to prevent the molecular sieve particles from passing through; the chip groove 32 is a space formed by the lower end of the H-shape and the upper surface of the liquid core 2. It can be processed by cutting or welding. The manufacturing method is not limited in the present invention, as long as the design requirements are met.

[0055] The present invention sets the adsorption core 3 as an H-shaped structure to provide a stable support platform for the molecular sieve particles 5 through its crossbeam. This design ensures that the molecular sieve particles can be evenly distributed in the gas channel and will not be displaced or fall off due to the impact or vibration of the airflow. Compared with other shapes (such as rectangles or circles), the H-shaped structure has higher rigidity in the vertical direction. This helps to resist the influence of external pressure or vibration on the adsorption core and maintain the stability and integrity of its structure. The H-shaped structure makes the gas channel 31 present an optimized path in the cross section. This path design helps to reduce the turbulence and resistance of the airflow in the channel and improve the circulation efficiency of the gas. Through the chip holes 33 on the H-shaped crossbeam (the size of these chip holes is smaller than the size of the molecular sieve particles 5 to prevent particles from passing through), the gas can be evenly distributed on the molecular sieve particles 5, thereby improving the adsorption efficiency. The lower end of the H-shaped and the upper surface of the liquid core 2 together form a chip groove 32, and baffles 34 are also provided at both ends of the chip groove 32 to prevent the escape of powder due to airflow. This space is specifically used to collect powder that may fall off the molecular sieve particles 5 during use. This design not only facilitates the centralized processing of powder chips, but also avoids the diffusion and accumulation of powder chips in the system, which would have an adverse effect on system performance.

[0056] The material of the seal 6 is a metal material with good thermal conductivity, such as aluminum alloy or copper. The main function of the seal 6 and the first fixed plate 11 and the second fixed plate 12 is to provide a physical position for processing screw holes when the fixing frames on both sides are installed with screws. At the same time, the seal 6 ensures the airtightness between the adsorption core 3 and the liquid core 2. The seal 6 effectively prevents the leakage of gas or coolant, thereby ensuring the sealing performance of the entire system. In the gas channel 31, the molecular sieve particles 5 may produce detached powder due to various factors (such as vibration, airflow impact, etc.). If these powders spread to the outside of the system or enter other areas that should not be contacted, they will have an adverse effect on the performance of the system. The setting of the seal 6 helps to form a relatively closed space between the adsorption core 3 and the liquid core 2 to prevent it from further spreading. The seal 6 not only plays a sealing role, but also can reduce the loosening or displacement of components caused by vibration or external force.

[0057] In this embodiment, the first fixed plate, the second fixed plate, the adsorption core, the liquid core and the seal are brazed together. Brazing is to apply solder to the parts where the parts contact each other in advance, and then stack the parts together according to the structural requirements, heat them in a vacuum furnace to melt the solder to achieve welding. The welding connection can ensure the close connection between the various components and improve the strength and stability of the overall structure. The welded structure helps to reduce gaps and leaks at the joints, thereby improving the sealing performance of the system. This is particularly important for gas treatment systems that need to maintain airtightness.

[0058] When in use, the adsorption core 3 of the gas molecule adsorption device is installed in the gas circulation flow field structure in the closed working chamber of the laser. When the laser is working, when the circulating working gas passes through the adsorption core 3, the molecular sieve particles 5 adsorb the ground state HF / DF gas molecules therein in real time. The liquid passing core 2 can cool and heat the molecular sieve particles. When the laser is working, the low-temperature liquid is passed to absorb the heat generated by the adsorption of the molecular sieve particles 5 in real time, and the temperature of the molecular sieve particles 5 is kept stable to stabilize its adsorption capacity. When the adsorption of the molecular sieve particles 5 is close to saturation, high-temperature liquid can be passed when the laser is not working, so that the gas molecules adsorbed by the molecular sieve particles 5 are quickly released, and the laser's vacuum device (vacuum pump) is used to extract them out of the closed working chamber, so as to realize the online desorption and regeneration of the molecular sieve particles and achieve the purpose of long-term reuse.

[0059] Adding this gas molecule adsorption device to a hundred-watt pulsed HF / DF laser with an average power can reduce the laser power by no more than 10% of the initial power.

[0060] A method for assembling a gas molecule adsorption device is implemented based on the above-mentioned gas molecule adsorption device, and the specific steps are as follows:

[0061] S1. Ensure that the fixing frame 1, the liquid-permeable core 2, the adsorption core 3, the sealing strip 6 and the anti-leakage net 4 are fully prepared and check their integrity.

[0062] S2. Place a liquid-permeable core 2 on the second fixing plate 12 of the fixing frame 1.

[0063] S3. Place an adsorption core 3 on the upper surface of the liquid-permeable core 2, and then place them alternately in the order of first the liquid-permeable core 2 and then the adsorption core 3, until the last liquid-permeable core 2 is placed in the last layer.

[0064] S4. Place the first fixing plate 11 of the fixing frame 1 on the upper surface of the last layer of liquid-permeable core 2.

[0065] S5. Place the seal strips 6 on both sides of the adsorption core 3 so that the outer end surfaces of the seal strips 6 are flush with the outer end surfaces of the liquid-permeable core 2.

[0066] S6. Weld the first fixing plate 11, the second fixing plate 12, the adsorption core 3, the liquid-permeable core 2 and the sealing strip 6 into one.

[0067] S7. Place the molecular sieve particles 5 into the gas channels 31 of the adsorption core 3 , so that the molecular sieve particles 5 fill all the gas channels 31 .

[0068] S8. Install the anti-leakage net 4 on the end surfaces of the first fixing frame 13 and the second fixing frame 14 of the fixing frame 1 facing the air inlet and the air outlet of the adsorption core 3.

[0069] S9. Use screws to fix the first fixing frame 13 and the second fixing frame 14 installed with the anti-leakage net 4 in step S8 to the first fixing plate 11, the second fixing plate 12 and the sealing strip 6 respectively.

[0070] In this embodiment, the gas molecule adsorption device also includes two liquid side heads 7. When the two liquid side heads 7 are connected to the fixed frame 1, the liquid core 2 and the adsorption core 3 by welding, the two liquid side heads 7 will be welded together with the first fixed plate 11, the second fixed plate 12, the adsorption core 3, the liquid core 2 and the seal 6 into an integrated structure in step S6. However, if the liquid side heads 7 are connected to the fixed frame 1, the liquid core 2 and the adsorption core 3 by a non-welding connection method (such as bolt connection, snap-on fixing, etc.), the fixing step in step S9 is first completed, and then the two liquid side heads 7 are respectively connected to the fixed frame 1, the liquid core 2 and the adsorption core 3.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors.
