[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the raw material gas is first sent into the lower part of the diversion tank through the air inlet pipe and rises under the action of buoyancy. The particulate dust and impurities therein are separated through the filtering action of the dust removal component, so that the raw material gas passing through the dust removal component is in a relatively pure state. Further, the motor drives the central axis to drive the central axis and the spraying component to slowly rotate. Low-temperature water is provided to the spraying component through the water pump and the liquid outlet pipe and is dispersed into water mist by the spraying component and sprayed on the inner side of the diversion tank, reacting with water vapor and oil stains to promote their precipitation from the raw material gas, realizing the separation and treatment of impurities in the raw material gas.

[0020] 2. The present invention filters and processes the dust and unreacted particulate matters in the raw material gas through the filter screen. Further, the pressure difference sensors arranged on the upper and lower sides of the first central ring are used to monitor the pressure difference on both sides of the filter screen in real time to judge the filtering effect. When the pressure difference exceeds the preset value, the electric telescopic rod extends and drives the L-shaped block to be clamped into the second communication groove, so that the L-shaped block is buckled with the second communication groove and the first central ring and the scraper can rotate along with the central axis, thereby realizing the cleaning of the lower end of the filter screen, preventing blockage, reducing the maintenance frequency, and improving the service life and cycle.

[0021] 3.

The low-temperature water is formed into a conical water mist by the high-pressure nozzle and sprayed out. Then, the affinity and heat exchange effects between the low-temperature water and the oil mist and moisture in the raw material gas are utilized to promote the condensation of the oil mist and moisture into a liquid state, and agglomerated water is formed on the surface of the liquid droplets. Under the action of gravity, it falls into the V-shaped water guide plate and flows back to the liquid storage cavity through the second support ring and the return water pipe for oil and dirt separation and circulating spraying. The residual moisture is removed by the dehumidifying particles filled in the dehumidifying plate, thereby realizing the pretreatment of the oil and dirt and moisture in the raw material gas.

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0034] Example 1, as Figure 1 shown, a gas diversion support device for a hydrogen extraction adsorption tower, including a support frame 1, the upper end of the support frame 1 is fixedly connected with an adsorption tower support structure 2, several windows 3 are arranged on the outer surface of the adsorption tower support structure 2, an inlet pipe 6 is opened at the lower part of the outer surface of the adsorption tower support structure 2, an outlet pipe 4 is opened at the upper part of the outer surface of the adsorption tower support structure 2, and a drive cabinet 5 is fixedly connected at the lower part of the outer surface of the adsorption tower support structure 2.

[0035] Among them, the adsorption tower support structure 2, as a pre-device of the adsorption tower, is used to support the adsorption tower to ensure its stability, and at the same time can pre-treat the raw material gas required by the adsorption tower, so as to remove dust, moisture and oil mist, protect the adsorbent and other components in the adsorption tower, extend its service life and reduce the maintenance frequency.

[0036] Further, to drive the operation of the adsorption tower support structure 2, refer to Figure 2, a liquid storage chamber 51 and an electrical chamber 52 are sequentially arranged in the inner cavity of the drive cabinet 5 from top to bottom. A water pump 54 is fixedly connected to the bottom wall of the inner cavity of the liquid storage chamber 51. The output end of the water pump 54 is fixedly connected to a liquid outlet pipe 56 communicating with the adsorption tower support structure 2. A fuel tank 57 is fixedly connected to the bottom wall of the inner cavity of the liquid storage chamber 51. The upper end of the fuel tank 57 is fixedly connected to a flotation float 55 through a conduit. A motor 53 is fixedly connected to the bottom wall of the inner cavity of the electrical chamber 52 through a bracket. The output end of the motor 53 is drivingly connected to the adsorption tower support structure 2 through a transmission belt.

[0037] A cooling device is also installed in the liquid storage chamber 51, which can reduce the temperature of the water stored in the liquid storage chamber 51 to a preset temperature. Further, the water pump 54 transports low-temperature water into the adsorption tower support structure 2 through the liquid outlet pipe 56, and receives the water containing oil and grease sent back by the adsorption tower support structure 2. The oil and grease are collected by the flotation float 55 suspended above the water surface and below the oil surface, and are sent into the fuel tank 57 for storage through a conduit, realizing the separation of the oil and grease. The technology of separating oil and water through the buoyancy difference between oil and water and the characteristics of the float is very mature in the existing production environment, and will not be described and demonstrated in detail in the present invention.

[0038] Further, to realize the pretreatment of the hydrogen production raw material gas, refer to Figure 2 , the adsorption tower support structure 2 includes a diversion tank 21 fixedly connected to the upper end of the support frame 1. A dust removal assembly 22 is arranged at the lower part of the inner surface of the diversion tank 21. A water-gas isolation assembly 28 is arranged in the middle of the inner surface of the diversion tank 21. A dehumidification plate 25 is fixedly connected to the upper part of the inner surface of the diversion tank 21. Drying particles are filled inside the dehumidification plate 25. A central shaft 23 is rotatably connected to the lower end of the dehumidification plate 25, penetrates through the water-gas isolation assembly 28 and the dust removal assembly 22 and extends to the bottom wall of the inner cavity of the diversion tank 21 and is drivingly connected to the motor 53. A spray assembly 24 is fixedly connected to the upper part of the outer surface of the central shaft 23. A waste box 27 is fixedly connected to the lower end of the diversion tank 21. A track frame 26 is slidably connected to the inner surface of the waste box 27.

[0039] During the operation of this embodiment, the raw material gas first enters the lower part of the diversion tank 21 through the inlet pipe 6 and rises under the action of buoyancy. The particulate dust and impurities are separated through the filtering action of the dust removal assembly 22, so that the raw material gas passing through the dust removal assembly 22 is in a relatively pure state. Further, the motor 53 drives the central shaft 23 to drive the central shaft 23 and the spray assembly 24 to slowly rotate. Low-temperature water is provided to the spray assembly 24 through the water pump 54 and the liquid outlet pipe 56, and is dispersed into water mist through the spray assembly 24 and sprayed on the inner side of the diversion tank 21, reacting with water vapor and oil and grease to promote their precipitation from the raw material gas, realizing the separation and treatment of impurities in the raw material gas.

[0040] Embodiment 2. On the basis of Embodiment 1, this embodiment filters the dust and unreacted particulate matter in the raw gas through the filter screen 222. Further, the pressure difference sensors arranged on both sides of the central ring 1 223 are used to monitor the pressure difference on both sides of the filter screen 222 in real time to judge the filtering effect. When the pressure difference exceeds the preset value, the electric telescopic rod 2231 extends and drives the L-shaped block 2234 to be stuck into the second communication groove 232, so that the L-shaped block 2234 is buckled with the second communication groove 232 and the central ring 1 223 and the scraper 224 can rotate along with the central shaft 23, thereby realizing the cleaning of the lower end of the filter screen 222, preventing blockage, reducing the maintenance frequency, and improving the service life and cycle.

[0041] Specifically, to process the dust in the raw gas, refer to Figure 3 and Figure 4 , the dust removal assembly 22 includes a first support ring 221 fixedly connected to the inner surface of the diversion tank 21. A filter screen 222 is fixedly connected to the inner surface of the first support ring 221. A central ring 1 223 slidably connected to the outer surface of the central shaft 23 is fixedly connected to the inner surface of the filter screen 222. A plurality of scrapers 224 closely attached to the lower end of the filter screen 222 are fixedly connected to the outer surface of the central ring 1 223 in a circumferential distribution.

[0042] The first support ring 221 is a frame for supporting the filter screen 222, so that it can be fixed at a predetermined position on the inner surface of the diversion tank 21. The raw gas conveyed inward through the intake pipe 6 will rise under the action of buoyancy and enter the upper part of the filter screen 222 from the lower side of the filter screen 222. However, the dust and unreacted particulate matter therein cannot continue to move, but are blocked at the lower part of the filter screen 222, thereby realizing the separation of solid impurities in the raw gas by using the filter screen 222;

[0043] However, as a kind of filter consumable, the filter screen 222 has a limited service life and needs to be cleaned and maintained frequently. To a certain extent, this will affect the processing progress of the raw gas and thus the working efficiency of the adsorption tower.

[0044] Further, to clean the filter screen 222 and reduce the maintenance frequency, refer to Figure 4 , Figure 5 and Figure 6 , rotating brushes 225 closely attached to the lower end of the filter screen 222 are rotatably connected to the front and rear symmetry of the inner surface of the scraper 224. A friction groove 2226 is formed on the inner surface of the filter screen 222. One side of the rotating brush 225 close to the friction groove 2226 penetrates the inner surface of the scraper 224 and is fixedly connected to a friction wheel 226 closely attached to the inner surface of the friction groove 2226. The lower part of the inner surface of the scraper 224 is an inclined surface, and a straight groove 2241 is formed on the bottom wall of the inner surface close to the central shaft 23.

[0045] The scraper 224 provided at the lower part of the filter screen 222 is connected to the first central ring 223 and can rotate around the central axis 23 following the first central ring 223. Furthermore, by means of the frictional effect between the friction wheel 226 and the friction groove 2226, the rotating brush 225 is driven to rotate. Fine hairs are provided on the surface of the rotating brush 225, which can clean the dust adsorbed on the lower part of the filter screen 222 during rotation and make it fall into the scraper 224. The bottom of the scraper 224 is a slope. In the state of small-amplitude movement, the dust particles will move along the slope towards the first central ring 223.

[0046] Furthermore, in order to drive the electric telescopic rod 2231 to actuate by using the pressure difference monitored by the pressure difference sensor and through the cooperation of the L-shaped block 2234 and the water storage tank 233 to make the scraper 224 rotate following the rotation of the central axis 23, refer to Figure 7 , pressure difference sensors are respectively provided on the upper and lower parts of the outer surface of the first central ring 223. An electric telescopic rod 2231 is fixedly installed on the inner surface of the first central ring 223. A chute 2233 is formed on the inner surface of the first central ring 223. The output end of the electric telescopic rod 2231 is fixedly connected with a buffer spring block 2232 which is slidably connected to the inner surface of the chute 2233. The lower end of the buffer spring block 2232 is fixedly connected with a connecting column extending through the inner surface of the chute 2233 to the inner cavity of the scraper 224. The lower end of the connecting column is fixedly connected with an L-shaped block 2234. A first communication groove 2235 penetrating through the left and right sides is formed in the horizontal part of the L-shaped block 2234. The vertical part of the L-shaped block 2234 is slidably connected to the inner surface of the straight groove 2241. When the L-shaped block 2234 is at the lowermost side of the straight groove 2241, the second communication groove 232 is communicated with the scraper 224 through the first communication groove 2235.

[0047] The above-mentioned pressure difference sensor is a mature technical means in the conventional technology. The present invention uses it to detect the pressure difference on both sides of the filter screen 222 and thereby controls the extension or retraction of the electric telescopic rod 2231. Its operating principle and control method are both conventional technical means in the existing technology, and the specific installation, wiring method and operating principle thereof will not be shown and described in detail in the present invention.

[0048] When a pressure difference exists between the upper and lower sides of the filter screen 222, the electric telescopic rod 2231 is driven to extend through a control signal. At this time, the electric telescopic rod 2231 pushes the buffer spring block 2232 to move downward, and thereby presses the L-shaped block 2234 to move downward through the buffer spring block 2232;

[0049] In the initial state, the horizontal part of the L-shaped block 2234 is in the water storage tank 233, and the slow rotation of the central axis 23 will not produce a transmission effect on it. There is also a rubber ring for providing resistance on the inner surface of the filter screen 222, which can prevent the first central ring 223 from rotating following the central axis 23 without a pressure difference;

[0050] When the buffer spring block 2232 presses down on the L-shaped block 2234, if the L-shaped block 2234 is not in the same position as the second communication groove 232, the L-shaped block 2234 cannot descend. At this time, the buffer spring block 2232 compresses and continuously provides pressure to the L-shaped block 2234 through the spring inside it until the horizontal part of the L-shaped block 2234 coincides with the second communication groove 232 in the vertical direction. Then the L-shaped block 2234 will be pressed into the second communication groove 232, and under the action of the second communication groove 232, the first central ring 223 and the scraper 224 will slowly rotate following the central shaft 23.

[0051] Further, to centrally process the dust particles cleaned by the scraper 224 and the rotary brush 225, refer to Figure 7 , a blanking pipe 231 communicating with the lower end of the diversion tank 21 is provided in the lower part of the inner surface of the central shaft 23, and a water storage tank 233 is provided in the upper part of the outer surface of the central shaft 23 inside the first central ring 223. The second communication grooves 232 penetrating to the outer surface of the central shaft 23 are annularly distributed at the position of the inner surface of the blanking pipe 231 below the water storage tank 233, and the second communication grooves 232 are in the same horizontal position as the scraper 224.

[0052] When the horizontal part of the L-shaped block 2234 enters the second communication groove 232, the second communication groove 232, the first communication groove 2235, and the scraper 224 are all in the same horizontal position. That is to say, at this time, the scraper 224 can communicate with the blanking pipe 231, and the particulate impurities therein can also enter the intake pipe 6 through the blanking pipe 231 and be temporarily stored.

[0053] Embodiment 3: On the basis of Embodiment 2, this embodiment further uses the liquid outlet pipe 56 to supply water to the spraying assembly 24 and send it into the high-pressure nozzle 244 through the conveying action of the water storage tank 233 and the water supply pipe 245. The high-pressure nozzle 244 sprays the low-temperature water to form a conical water mist. Then, by using the affinity and heat exchange effects between the low-temperature water and the oil mist and moisture in the raw material gas, the oil mist and moisture are promoted to condense into a liquid state and adhere to the surface of the liquid droplets to form agglomerated water. Under the action of gravity, it falls into the V-shaped water guide plate 285, and returns to the liquid storage cavity 51 through the second support ring 281 and the return water pipe 286 for oil and water separation and circulating spraying. The residual moisture is removed by the dehumidifying particles filled in the dehumidifying plate 25, thereby realizing the pretreatment of the oil and moisture in the raw material gas.

[0054] Specifically, to process the oil mist and large-particle moisture in the raw material gas, refer to Figure 8, a water storage tank 233 is provided on the upper part of the inner surface of the central shaft 23. A water slip ring 234 is rotatably connected to the upper part of the outer surface of the central shaft 23. The liquid outlet pipe 56 is fixedly connected to the water slip ring 234 and communicates with the inner cavity of the water slip ring 234. The inner surface of the water slip ring 234 communicates with the inner cavity of the water storage tank 233 through a notch. The part of the outer surface of the central shaft 23 below the water slip ring 234 is fixedly connected to the spraying assembly 24. The water slip ring 234 is connected to the liquid outlet pipe 56 and can continuously supply low-temperature water to the water storage tank 233. Through the continuous water supply of the water pump 54 connected to the liquid outlet pipe 56, the provided water slip ring 234 can continuously supply water to the water storage tank 233 without affecting the rotation of the central shaft 23.

[0055] Further, to achieve the preliminary separation of oil mist and moisture in the raw material gas, refer to Figure 8 , the spraying assembly 24 includes a support rod 241 fixedly connected to the outer surface of the central shaft 23. A hollow pipe 246 communicating up and down is provided on the inner surface of the support rod 241. An air suction hood 243 is fixedly connected to the upper end of the hollow pipe 246. A diversion hood 242 is fixedly connected to the lower end of the hollow pipe 246. A water supply pipe 245 communicating with the inner cavity of the water storage tank 233 is fixedly connected to the inner surface of the support rod 241. A high-pressure nozzle 244 communicating with the water supply pipe 245 is provided in the middle of the inner surface of the hollow pipe 246.

[0056] The water in the water storage tank 233 will enter each high-pressure nozzle 244 through the water supply pipe 245 and be sprayed out through the water outlet of the high-pressure nozzle 244. The water outlet holes of the high-pressure nozzle 244 are very fine, and the water can be sprayed out in the form of water mist. The sprayed water will form a large-area water mist in the diversion tank 21, and the spraying assembly 24 rotates continuously with the central shaft 23, and can form a swirling water mist, increasing the contact area between the water mist and the raw material gas. When the low-temperature water mist meets the raw material gas, part of the water in the raw material gas can be cooled and aggregated on the surface of the liquid droplets to form agglomerated water droplets and fall. Synchronously, the oil stain is also condensed under the action of the low-temperature water mist and adheres to the agglomerated liquid droplets and falls with the liquid droplets to be collected in the gas-liquid separation assembly 28 and flows back to the liquid storage cavity 51.

[0057] Further, during the spraying process, since the water flow is sprayed downward, a negative pressure will be formed in the diversion hood 242, and then the heavier raw material gas in the upper layer of the hollow pipe 246 will be redrawn through the hollow pipe 246 and the air suction hood 243 and subjected to secondary treatment through water mist spraying.

[0058] The above-mentioned "heavier raw material gas" refers to the raw material gas that still carries water vapor after being spray-treated once. Due to its certain buoyancy, the upward movement of the fuel gas separated from the water is relatively slow, and it is more easily affected by the air flow. Thus, this part of the raw material gas is screened out and drawn back to the lower part of the diversion hood 242 through the hollow tube 246 and the suction hood 243 for diversion, and then the water in it is precipitated again. Since these raw material gases are not far below the diversion hood 242 after being drawn back, the water temperature here is relatively lower, and the water mist in the raw material gas can be precipitated more quickly.

[0059] Further, to achieve the recovery and treatment of water and oil stains, refer to Figure 9 and Figure 10 The water-gas isolation component 28 includes a second support ring 281 fixedly connected to the inner surface of the diversion tank 21 and a second central ring 282 rotatably connected to the outer surface of the central axis 23 at the center of the second support ring 281. A number of V-shaped water guide plates 285 are fixedly connected to the lower part of the inner surface of the second support ring 281 in a linear distribution, and a number of V-shaped gas guide plates 287 are fixedly connected to the upper part of the inner surface of the second support ring 281 in a linear distribution. The adjacent V-shaped water guide plates 285 and V-shaped gas guide plates 287 are staggered. A baffle 284 is fixedly connected to the upper ends of a number of V-shaped gas guide plates 287. A number of T-shaped exhaust holes 283 are linearly distributed and opened at the top of the inner surface of a number of V-shaped gas guide plates 287. Communication holes 288 are opened in the part of the inner surface of the second support ring 281 located below the inner surface of the V-shaped water guide plates 285 and communicate with its inner cavity. A water return pipe 286 fixedly connected to the outer surface of the second support ring 281 and communicating with the inner cavity of the liquid storage cavity 51 and the inner cavity of the second support ring 281 is provided.

[0060] To prevent droplets from entering the lower dust removal component 22 and affecting the normal operation of the dust removal component 22, a baffle 284 is installed on the V-shaped gas guide plate 287 to block the water droplets. And through the staggered V-shaped gas guide plates 287 and the baffle 284, the water is finally collected into the V-shaped water guide plates 285 and enters the inner cavity of the second support ring 281 through the communication holes 288, and finally flows back to the liquid storage cavity 51 through the water return pipe 286. The gas entering the V-shaped gas guide plates 287 below will be shunted through the exhaust holes 283 and float upward through the baffle 284 and enter the range of the water mist.
