Description

Technical Field

[0001] This utility model relates to the field of gas purification technology, and specifically to a gas purification device. Background Technology

[0003] For example, Chinese patent CN219186389U discloses a purification device for nitrogen, oxygen, argon, and helium, relating to the field of chemical gas purification technology. Specifically, it describes a purification device for nitrogen, oxygen, argon, and helium, comprising a cylindrical box with a semi-circular rectangular tube at the top. This purification device, through the setting of a limiting rod, prevents the sixth support block from shaking with the semi-circular rectangular tube. The coordinated arrangement of the semi-circular rectangular tube, support shaft, and sixth support block improves the utilization rate of the molecular sieve adsorbent. The convex column prevents the third support column from detaching. The coordinated arrangement of the third, first, and second support columns enhances purification performance.

[0004] However, the above-mentioned simple purification equipment requires shutdown after the adsorption material is saturated, making continuous production impossible. The adsorption material is also subject to strong impact and friction from the airflow, which can easily cause the molecular sieve to pulverize.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example 1

[0038] Please refer to the instruction manual appendix. Figure 1 A gas purification device, including a first conduit 5;

[0039] A flow meter 1 and an analyzer 4 are installed on the first pipeline 5;

[0040] The first pipe 5 is connected to an adjustable air intake assembly;

[0043] The first adsorption container 2 and the second adsorption container 3 are connected to an adjustable purified gas discharge assembly for the discharge of purified gas and an exhaust gas discharge assembly for the discharge of waste gas.

[0044] When the adsorption material in the second adsorption container 3 reaches saturation, the first adsorption container 2 purifies and the second adsorption container 3 regenerates. The regulating inlet assembly and the regulating purified gas outlet assembly are connected to the first adsorption container 2, allowing the gas to be purified to enter through the regulating inlet assembly.

Simultaneously, the regulating regeneration gas assembly and the exhaust gas outlet assembly are connected to the second adsorption container 3, allowing the regeneration gas from the regulating regeneration gas assembly to enter the second adsorption container 3, removing impurities such as water, carbon monoxide, carbon dioxide, and hydrocarbons. Finally, the gas is discharged through the exhaust gas outlet assembly.

Finally, the regeneration gas is discharged through the exhaust gas outlet assembly. This system effectively controls the adsorption and switching between the first adsorption container 2 and the second adsorption container 3, improving the recovery efficiency of the purified gas and the lifespan of the adsorbent. It also allows for accurate calculation of the adsorption capacity of the first adsorption container 2 and the second adsorption container 3.

[0049] The first adsorption container 2 purifies, the second adsorption container 3 regenerates, the first control valve 6 of the regulating air intake assembly and the sixth control valve 18 of the regulating purified gas discharge assembly are opened, the fifth pipe 14, the tenth pipe 17, and the seventh pipe 21 are connected to the first adsorption container 2, and the third control valve 9, the second control valve 7, the seventh control valve 19, and the eighth control valve 22 are closed. The gas to be purified enters the first adsorption container 2 through the fifth pipe 14 of the regulating air intake assembly, the first adsorption container 2 purifies, and the purified gas passes through the regulating purified gas discharge assembly. The tenth pipe 17 and the seventh pipe 21 discharge. At the same time, the fifth control valve 11 and the fourth control valve 10 of the regulating regeneration gas assembly and the ninth control valve 25 of the exhaust gas discharge assembly are opened. The third pipe 12, the fourth pipe 13 and the ninth pipe 24 are connected to the second adsorption container 3. The regeneration gas of the regulating regeneration gas assembly enters the second adsorption container 3 through the third pipe 12 and the fourth pipe 13 to remove impurities such as water, carbon monoxide, carbon dioxide and hydrocarbons in the second adsorption container 3. Finally, it is discharged from the ninth pipe 24 and the vent pipe 20 of the exhaust gas discharge assembly.

[0050] When the adsorbent material in the first adsorption container 2 reaches saturation, the second adsorption container 3 purifies and the first adsorption container 2 regenerates.

Simultaneously, the second control valve 7 of the regulating regeneration gas assembly and the seventh control valve 19 of the exhaust gas discharge assembly are opened, and the third pipe 12, the eleventh pipe 15, the sixth pipe 16, and the vent pipe 20 are connected to the first adsorption container 2. The regeneration gas from the regulating regeneration gas assembly enters the first adsorption container 2 through the third pipe 12 and the eleventh pipe 15, removing impurities such as water, carbon monoxide, carbon dioxide, and hydrocarbons from the first adsorption container 2. Finally, it is discharged from the sixth pipe 16 and the vent pipe 20 of the exhaust gas discharge assembly. This effectively controls the adsorption and switching of the first adsorption container 2 or the second adsorption container 3, improving the recovery efficiency of the purified gas and the service life of the adsorbent.

[0051] Please refer to the instruction manual appendix. Figure 2-7 The second adsorption container 3 includes a tank body 31 and a tank cover 32. The tank cover 32 is fixedly installed on the top of the tank body 31. The upper end of the tank body 31 is connected to an energy-dissipating component 33 for reducing the energy consumption of the purified gas. The tank body 31 is provided with a pressing component 35 for compacting the adsorption material below the energy-dissipating component 33. The tank body 31 is provided with a feeding pipe 34 below the pressing component 35. The lower end of the inner wall of the tank body 31 is fixedly connected to a conical hollow hopper 37 for supporting the adsorption material. The discharge end of the conical hollow hopper 37 is fixedly connected to a discharge pipe 36, and the discharge pipe 36 is located at the outer end of the tank body 31.

[0052] The lid 32 of the second adsorption container 3 is connected to the fourth pipe 13 and the second pipe 8, and the lid 32 of the first adsorption container 2 is connected to the fifth pipe 14 and the eleventh pipe 15.

[0053] The tank 31 of the second adsorption container 3 is connected to the eighth pipe 23 and the ninth pipe 24, and the tank 31 of the first adsorption container 2 is connected to the sixth pipe 16 and the tenth pipe 17.

[0054] Both the injection pipe 34 and the discharge pipe 36 are equipped with control valves at their outer ends for controlling the sealing of the injection pipe 34 and the discharge pipe 36.

[0055] The energy dissipation component 33 includes a follower-type rotating component and an energy-consuming component. Both the follower-type rotating component and the energy-consuming component are connected to the flow meter 1, and the follower-type rotating component and the energy-consuming component are movably connected.

[0056] The follow-up rotating component includes a rotating cam 331, a horizontal shaft 332, and blades 338. The tank body 31 is rotatably connected to the horizontal shaft 332 via a bearing. Blades 338 are fixedly connected at equal intervals along the circumference on the part of the tank body 31 located inside the tank body 31. The rotating cam 331 is fixedly connected to the outer end of the horizontal shaft 332. The rotating cam 331 is movably connected to the energy-consuming component.

[0057] The energy-consuming components include a bearing 333, a mounting bracket 334, a first spring 335, a horizontal support plate 336, and a sliding rod 337. The horizontal support plate 336 is fixedly installed on the outer wall of the tank 31. The first spring 335 is fixedly connected to the top of the horizontal support plate 336. The mounting bracket 334 is fixedly connected to the top of the first spring 335. The bearing 333 is rotatably connected to the mounting bracket 334. The bearing 333 is movably connected to the rotating cam 331. The sliding rod 337 is fixedly connected to the bottom of the mounting bracket 334. The bottom of the sliding rod 337 is in contact with and slidably connected to the straight hole opened in the horizontal support plate 336.

[0058] When the rotating cam 331 is separated from the bearing 333 and the first spring 335 is in its normal state, the top of the bearing 333 is 2cm higher than the bottom of the rotating cam 331 at its lowest point.

[0059] Gas enters the tank body 31 through the can lid 32. The gas drives the blades 338 of the follower rotating component of the energy dissipation component 33 to rotate. The blades 338 drive the horizontal shaft 332 to rotate. The horizontal shaft 332 drives the rotating cam 331 to rotate. The rotating cam 331 contacts the bearing 333 of the energy dissipation component and pushes the bearing 333 to move downward. The bearing 333 drives the mounting bracket 334 to move downward. The mounting bracket 334 drives the first spring 335 to compress downward. After the rotating cam 331 separates from the bearing 333, the restoring force of the first spring 335 pushes the mounting bracket 334 upward and pushes the bearing 333 upward. During this process, the energy required for the compression of the first spring 335 is not reused. This part of the energy is the energy of the gas flow, which reduces the impact on the adsorbent material, reduces the friction between the adsorbent materials, and reduces the possibility of adsorbent material pulverization.

[0060] The clamping assembly 35 includes a rocker arm 351, a palm pad 352, a crankshaft 353, and a second spring 354. The inner wall of the can 31 rotates with the crankshaft 353 via a bearing. The bent part of the crankshaft 353 is fixedly connected to the top of the second spring 354 via a rotating ring. The bottom of the second spring 354 is fixedly connected to the palm pad 352, which is in close contact with and slidably connected to the inner wall of the can 31. One end of the crankshaft 353 is fixedly connected to the rocker arm 351, and the rocker arm 351 is located on the outside of the can 31.

[0061] When the adsorbent material needs to be replaced, rotate the rocker arm 351 of the clamping assembly 35. The rocker arm 351 causes the curved part of the crankshaft 353 to face upwards. The crankshaft 353 causes the second spring 354 to move upwards. The second spring 354 causes the palm pad 352 to move upwards until it is higher than the injection pipe 34, opening the valve on the discharge pipe 36. The adsorbent material on the conical hollow bucket 37 is discharged through the discharge pipe 36. After contact, the discharge pipe 36 is blocked, and the adsorbent material enters the tank 31 through the injection pipe 34. Finally, rotate the rocker arm 351. The rocker arm 351 causes the curved part of the crankshaft 353 to face downwards. The crankshaft 353 causes the second spring 354 to move downwards. The second spring 354 causes the palm pad 352 to move into contact with the adsorbent, pressing the adsorbent material on the conical hollow bucket 37 tightly to prevent the adsorbent material from loosening or rubbing, further reducing the possibility of adsorbent material pulverization and extending the service life of the adsorbent material.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
