Description

Technical Field

[0001] This utility model relates to the technical field of thermoplastic polyurethane devices, and in particular to a device for recovering desorption gas in the preparation of high-purity hydrogen. Background Technology

[0002] As is well known, desorbed gas is a gas produced in the coal chemical industry. Its main components are carbon monoxide, hydrogen sulfide, and other gases. It is characterized by being explosive, having large pressure fluctuations, low calorific value, and producing a lot of waste gas. When desorbed gas is used as a raw material for methanol production, it not only utilizes the hydrogen element in it, but also achieves chemical equilibrium with natural gas. Methanol production from natural gas has the problem of having more hydrogen than carbon. The excess hydrogen is generally emitted or used as fuel, while desorbed gas has a carbon monoxide content as high as 50%, which can be matched with hydrogen to synthesize methanol.

[0003] Chinese patent CN220918594U describes a device for recovering desorption gas during the preparation of high-purity hydrogen. The device includes a water tank, a first gas pipe connected to the top of the water tank, a heating layer connected to the water tank, an activated carbon filter fixedly connected to one end of the first gas pipe, a second gas pipe fixedly connected to one side of the activated carbon filter, an adsorption tower connected to one end of the second gas pipe, a post-filter fixedly connected to one side of the adsorption tower, a motor body fixedly connected to the top inside the post-filter, and a stirring rod connected to the output end of the motor body.

[0004] In actual use, the following problems still exist:

[0005] Carbon monoxide in the desorbed gas is a non-hydrophilic gas. Dust and other hydrophilic toxic gases contained within the gas can affect the utilization of carbon monoxide in the desorbed gas. The conventional method is to introduce the desorbed gas into the filtrate, which then filters out the dust and other hydrophilic toxic gases. To improve filtration efficiency, the filtrate is usually stirred. However, the bubbles formed by the introduced desorbed gas in the filtrate are large, resulting in insufficient mixing between the filtrate and the desorbed gas, and low efficiency in filtering hydrophilic toxic gases. At the same time, the large bubbles in the desorbed gas rise quickly, and incomplete filtration or entry into the collection tank also results in incomplete filtration.

[0006] Therefore, a device for recovering desorbed gas during the preparation of high-purity hydrogen is proposed. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a device for recovering desorption gas in the preparation of high-purity hydrogen.

The fixed end of the vortex mixing component is connected to the outer wall of the rotary tube, and the movable end of the flow guiding vibration component is connected to the outer wall of the rotary tube.

[0011] The swirling mixing components are provided in several parts and are evenly distributed on the swirling tube. Each swirling mixing component includes a rotating ring, blades, and a oscillating component. The inner wall of the rotating ring is fixedly connected to the outer wall of the swirling tube, and the outer wall of the rotating ring is connected to the blades through the oscillating component.

[0012] The swinging component includes a swing rod, a limiting block, a rotating shaft, and a spring. The outer wall of the rotating ring is provided with a swing groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This high-purity hydrogen preparation desorption gas recovery device utilizes a rotating tube. During operation, the rotating tube, through a gas inlet, generates shear force on the desorption gas against the filtrate, breaking it into small bubbles. This ensures that hydrophilic impurities in the desorption gas fully contact the filtrate, increasing the fusion rate between the impurities and the filtrate. This avoids insufficient contact between the desorption gas and the filtrate, thus improving the filtration efficiency of hydrophilic impurities. The device also employs blades to create lateral flow in the filtrate, further enhancing contact and fusion speed. Simultaneously, the blades are in an oscillating state, utilizing the oscillation of the blades to generate… The impact force further breaks up the bubbles formed by the desorbed gas in the filtrate, allowing for more thorough contact between the desorbed gas and the filtrate, thus improving the filtration efficiency of hydrophilic impurities. The inclined guide plate causes the desorbed gas to rise continuously along its lower surface, increasing the contact time between the desorbed gas and the filtrate. Simultaneously, the vibration of the guide plate prevents small bubbles from merging into large bubbles, thus avoiding insufficient mixing between the desorbed gas and the filtrate during its ascent and improving the filtration efficiency of hydrophilic impurities. The centrifugal force generated by the combination of the vortex tube and blades, along with the lateral flow of the filtrate, prevents waste of filtrate caused by solid impurities accumulating on the bottom wall of the chamber during drainage, thereby improving the utilization efficiency of the filtrate.

[0031] like Figure 5-6 As shown, the swing component includes a swing rod 16, a limiting block 17, a rotating shaft 18, and a spring 19.

[0032] like Figure 5 and Figure 7 As shown, the air guide hole 13 is inclined, and the air guide hole 13 is inclined along the spiral tube 9 towards the air inlet tube 5.

[0033] like Figure 3 , Figure 4 and Figure 7 As shown, the flow guiding vibration component includes a flow guide plate 21 and a vibrating element. The two sides of the flow guide plate 21 are fixedly connected to the inner walls of the housing 4 located on both sides of the swirl tube 9. The side of the flow guide plate 21 away from the air intake pipe 5 is fixedly connected to the inner wall of the housing 4 away from the air intake pipe 5, and the flow guide plate 21 and the housing 4 form a semi-enclosed space. The position of the side of the flow guide plate 21 near the air intake pipe 5 is higher than the position of the side of the flow guide plate 21 away from the air intake pipe 5. The lower surface of the flow guide plate 21 is connected to the swirl tube 9 through the vibrating element.

[0034] like Figure 7 As shown, the vibrating component includes a guide plate 22 and a vibrating column 23. The top end of the guide plate 22 is fixedly connected to the lower surface of the guide plate 21, and the bottom end of the vibrating column 23 is fixedly connected to the outer wall of the vortex tube 9. The bottom end of the guide plate 22 is in contact with the top end of the vibrating column 23.

[0035] The work process is as follows:

[0036] S1. In use, the filtrate is first introduced into the housing 4 through the inlet pipe 7. The air inlet pipe 5 is connected to the air intake device. The servo motor 12 is started. The servo motor 12 drives the vortex tube 9 to start rotating through the coupling 11. The air intake device introduces the desorbed gas into the filtrate through the air inlet pipe 5, the vortex tube 9 and the air guide hole 13 in sequence to filter the hydrophilic impurities in the desorbed gas. During the rotation, the vortex tube 9 generates shear force on the desorbed gas through the vortex tube 9 and the filtrate at the air guide hole 13, shearing the desorbed gas into small bubbles. This allows the hydrophilic impurities in the desorbed gas to fully contact the filtrate, thereby improving the fusion speed between the hydrophilic impurities and the filtrate. This avoids insufficient fusion of hydrophilic impurities and the filtrate due to insufficient contact between the desorbed gas and the filtrate, thus improving the filtration efficiency of hydrophilic impurities.

[0037] S2, during the fusion process of hydrophilic impurities in the desorbed gas, the swirl tube 9, through the cooperation of the rotating ring 14, the rotating shaft 18 and the swing rod 16, causes the blade 15 to rotate around the swirl tube 9, thereby causing the filtrate to flow away from the air inlet pipe 5, further enabling the desorbed gas and the filtrate to come into full contact and improving the fusion speed of the hydrophilic impurities and the filtrate. At the same time, the guide plate 21 and the box 4 form a semi-enclosed space, and the pressure of the filtrate on the blade 15 is in a state of change. Since the blade 15 is rotatably connected to the rotating shaft 18 in the swing groove 20 through the swing rod 16, the blade 15 swings between the two limiting blocks 17. The blade 15 generates an impact force on the mixed solution of desorbed gas and filtrate, further breaking up the bubbles formed by the desorbed gas in the filtrate, making the desorbed gas and the filtrate come into full contact, and improving the filtration efficiency of hydrophilic impurities.

[0038] S3, during the fusion of hydrophilic impurities in the desorbed gas, the desorbed gas contacts the guide plate 21 as it rises in the filtrate. The inclined guide plate 21 causes the desorbed gas to rise continuously along its lower surface, increasing the contact time between the desorbed gas and the filtrate, thereby improving the fusion efficiency of the hydrophilic impurities. When the desorbed gas rises to the guide plate 21, the small bubbles easily merge into large bubbles. The vortex tube 9 drives the vibrating column 23 to rotate, and the vibrating column 23 vibrates by rubbing against the guide plate 22. The vibration is transmitted to the guide plate 21, avoiding insufficient mixing of the desorbed gas with the filtrate during its ascent due to the fusion of small bubbles into large bubbles, thus improving the filtration efficiency of hydrophilic impurities.

[0039] S4, during the fusion of hydrophilic impurities in the desorbed gas, the solid impurities in the desorbed gas generate centrifugal force through the cooperation of the swirl tube 9 and the blade 15. The solid impurities are thrown to both sides of the chamber 4. At the same time, the blade 15 causes the filtrate to flow away from the air inlet pipe 5. The solid impurities are more likely to be deposited at the bottom of the inner wall of the chamber 4 away from the air inlet pipe 5. The drain pipe 8 is set in the corresponding position to avoid the waste of filtrate caused by the solid impurities filling the bottom of the inner wall of the chamber 4 during the draining process, thereby improving the efficiency of filtrate use.

[0040] S5, after the desorbed gas completes the fusion of hydrophilic impurities from the filtrate, the desorbed gas enters the upper part of the housing 4, and the desorbed gas to be recovered is introduced into the collection tank 3 through the exhaust pipe 6 by the air pump 2, so as to carry out the next step of utilization of the desorbed gas.

[0041] To improve the stability of the blade 15's oscillation, a limiting block 17 and a swing rod 16 are connected by a spring 19. A secondary sealing box 10 is added to the inner wall of the housing 4 to prevent accidental leakage of the solution from damaging the servo motor 12. The air guide hole 13 is inclined along the spiral tube 9 towards the air inlet pipe 5. The gas ejected from the air guide hole 13 flows in the opposite direction to the flow of the filtrate. The impact force of the solution is used to further contact the desorbed gas with the filtrate. Since the filtrate is a liquid, it will inevitably produce vapor. A condenser and an activated carbon filter can be added to the exhaust pipe 6. The condenser and activated carbon filter are conventionally used in the prior art, so they are not described in the instruction manual or the accompanying drawings.

[0042] The parts of this utility model not described in detail are prior art. Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
