Description

Technical Field

[0001] The invention relates to the technical field of hydrogen production, and in particular to a high-pressure gas-liquid post-processing device. Background Art

[0002] As the problem of global warming becomes more prominent, all countries have included green hydrogen in their energy strategic planning. At present, green hydrogen is mainly produced by electrolysis of water. The electrolysis of water to produce hydrogen mainly uses a gas-liquid separator to achieve gas-liquid separation. Specifically, the hydrogen carrying liquid generated by the electrolyzer enters the hydrogen-side gas-liquid separator in a gas-liquid mixed state for gas-liquid separation, and the oxygen carrying liquid generated by the electrolyzer enters the oxygen-side gas-liquid separator in a gas-liquid mixed state for gas-liquid separation. When producing higher-purity hydrogen, a high-pressure gas post-processing device is required.

[0003] At present, the gas-liquid post-processing device is generally a cyclone-type gas-liquid separator. Due to the different densities of gas and liquid, when liquid and gas are mixed and flow together, the centrifugal force on the liquid is greater than that on the gas, so the liquid tends to be centrifugally separated. The liquid adheres to the separation wall and gathers downward due to gravity and is discharged through the discharge pipe.

[0004] Although the device can effectively remove moisture contained in the gas, due to the fast gas flow rate and high pressure in the process of hydrogen production by electrolysis, the gas will pass through the gas-liquid separator at a faster speed. Therefore, there is a part of the water droplets that cannot be effectively processed by the cyclone separator. The gas after separation contains high water and alkali content, which will cause certain corrosion to the subsequent pipelines and analytical instruments. When washing the gas in the later stage, the water content further increases, and the traditional gas-liquid separator is difficult to meet the requirements.

[0005] The existing patent (CN205461608U) discloses a hydrogen-oxygen-liquid-gas separator, comprising a separator body, on which a gas outlet, a washing tank, a separation chamber and a liquid outlet are sequentially arranged from top to bottom; a dripping net is arranged in the connecting channel between the gas outlet and the separator body; a water replenishing port is connected to the washing tank; a gas-liquid inlet and a cooling pipe are arranged at the separation chamber; the hydrogen-oxygen-liquid-gas separator of the utility model adopts an integrated structure as a whole, and the structure is relatively simple, and through the three processes of cooling, washing and filtering, the hydrogen-oxygen-liquid separation is more thorough, the water content and the alkali content are reduced to a minimum, which protects the subsequent equipment and prolongs the service life of the equipment.

[0006] However, in this scheme, the gas has a high initial water content, and it is difficult to achieve a good water removal effect by using only physical separation. Although the method of cooling the gas can condense some water droplets, when the air flow rate increases, the cooled water droplets will be taken away again. Summary of the invention

The gas carrying alkali liquid will pass through the air intake component and then enter the outer tube. The high-pressure gas will rotate and rise in the direction of the spiral blade.

The rising airflow will continue to flow through the bending cover and enter between the middle tube and the inner tube again for secondary treatment.

[0024] 3. The high-pressure gas-liquid post-treatment device is provided with a washing component. The gas treated by a gas-liquid separation component will be washed again. The washed gas will contain a certain amount of moisture, and then it can be treated again by another gas-liquid separation component, thereby effectively removing the alkaline liquid contained in the gas.

[0053] like Figure 1-10 As shown, the high-pressure gas-liquid post-processing device includes a support frame 1, a collecting box 2, a gas-liquid separation component 3 and a washing component 4. The collecting box 2 and the gas-liquid separation component 3 are provided with two, and are fixedly installed on the support frame 1. The washing component 4 is between the two gas-liquid separation components 3 and is connected end to end to the two gas-liquid separation components 3;

[0054] The gas-liquid separation component 3 includes an air intake component 301, an outer tube 302, an intermediate tube 303 and an inner tube 304. The air intake component 301 is installed on one side of the bottom end of the outer tube 302 and is connected to the inside thereof. The intermediate tube 303 is located in the outer tube 302 and is arranged concentrically therewith. A spiral blade 305 is provided between the outer tube 302 and the intermediate tube 303. The inner and outer circles of the spiral blade 305 respectively fix the intermediate tube 303 and the outer tube 302. The air intake component 301 corresponds to the bottom end of the spiral blade 305. The inner tube 304 is arranged in the intermediate tube 303 and is arranged concentrically therewith. The upper end of the outer tube 302 is fixed to the inner tube 304 by a concentric ring 306. The inner top wall of the concentric ring 306 is an arc-shaped structure. The arc-shaped structures respectively correspond to the cavity between the outer tube 302 and the intermediate tube 303 and the intermediate tube The cavity between the middle tube 303 and the inner tube 304, a plurality of spoiler components 307 are arranged between the middle tube 303 and the inner tube 304, the spoiler components 307 are respectively connected to the two, and are used to spoil the airflow entering between the middle tube 303 and the inner tube 304, a shaking component 308 is arranged in the inner tube 304, a bending cover 309 is arranged above the inner tube 304, the bottom end of the bending cover 309 corresponds to the shaking component 308, the upper end of the bending cover 309 is folded outward and passes through the concentric ring 306, and the concentric ring 306 is provided with a plurality of circular holes 310 penetrating inside and outside at the turning point of the bending cover 309, which are used to connect the inside and outside of the inner tube 304, an exhaust pipe 311 is arranged above the shaking component 308, the upper end of the exhaust pipe 311 passes through the concentric ring 306, and its side is sealed and fixed to the concentric ring 306;

[0055] It also includes a drainage assembly 312, which is installed at the bottom of the outer pipe 302 and the middle pipe 303;

[0056] The exhaust pipe 311 of one gas-liquid separation component 3 is connected to the air inlet end of the washing component 4, the exhaust end of the washing component 4 is connected to the air inlet component 301 of another gas-liquid separation component 3, the exhaust pipe 311 of another gas-liquid separation component 3 is connected to one of the collecting boxes 2, and the drainage components 312 of the two gas-liquid separation components 3 are both connected to another collecting box 2.

[0057] The hydrogen production process system can be mainly divided into: electrolyzer system, gas-liquid separation system, alkali liquid circulation system, hydrogen purification system and auxiliary system. The alkali liquid enters the electrolyzer and is electrolyzed to produce hydrogen and oxygen under the action of direct current. The hydrogen and oxygen entrained with alkali liquid enter the hydrogen separator and oxygen separator respectively for gas-water separation, and then enter the scrubber, cooler and gas-water separator respectively to cool the gas and further remove the alkali liquid in the gas. The gas-liquid separation component 3 plays the role of gas-water separator, and the washing component 4 plays the role of scrubber.

[0058] The spiral blades 305 are connected to the middle tube 303 and the outer tube 302 by welding, and sealing needs to be ensured at the weld. The inner tube 304 is supported and fixed by the outer tube 302 through the concentric ring 306, so that the outer tube 302, the middle tube 303 and the inner tube 304 are coaxial. The inner top walls of the bending cover 309 and the concentric ring 306 are both arc-shaped structures, and the two are coaxially arranged. The airflow flowing through the inner top wall of the concentric ring 306 can move together with the airflow flowing through the inner top wall of the bending cover 309.

[0059] The gas containing alkaline solution can first pass through a gas-liquid separation component 3, then be washed once, and finally pass through a gas-liquid separation component 3 again. This can not only effectively remove moisture from the gas, but also effectively reduce the alkaline solution content in the gas.

[0060] In an optional embodiment, the drainage assembly 312 includes an outer cone cover 3121 and an inner cone cover 3122. The outer cone cover 3121 is fixed to the bottom end of the outer tube 302, and the inner cone cover 3122 is fixed to the bottom end of the intermediate tube 303. A water storage chamber 3123 is fixedly installed at the lower end of the outer cone cover 3121, and a drainage pipe 3124 is fixedly installed at the bottom end of the water storage chamber 3123. The lower end of the inner cone cover 3122 extends into the water storage chamber 3123, and the drainage pipe 3124 is connected to the collection box 2.

[0061] The water storage chamber 3123 is a circular groove space, and the bottom end of the inner cone cover 3122 is a long tube, which extends into the water storage chamber 3123. When the gas and water are separated, the water storage chamber 3123 contains water, thereby achieving bottom sealing, and the bottom of the inner cone cover 3122 is inserted into the water, and its bottom is also in a sealed state, so that the gas will not leak from the bottom.

[0062] In an optional embodiment, the spoiler assembly 307 includes a semicircular raised ring 3071 and a semicircular grooved ring 3072 , wherein the semicircular raised ring 3071 is fixed to the outer wall of the inner tube 304 , and the semicircular grooved ring 3072 is fixed to the inner wall of the middle tube 303 , with an arc gap therebetween.

[0063] The spoiler component 307 is made by welding two metal rings, and is mainly used to block the direct airflow multiple times. The water droplets carried by the blocked airflow can collide with the spoiler component 307 and fall down.

[0064] In an optional embodiment, the shaking assembly 308 includes a cone ring 3081 and a jumping column 3082. The cone ring 3081 is provided with a plurality of cone rings, all of which are fixed to the inner wall of the inner tube 304. The inner ring of the cone ring 3081 extends downward, and the jumping column 3082 is located in the inner tube 304. The outer wall of the jumping column 3082 is provided with a plurality of cone-shaped raised rings 3083, and any cone-shaped raised ring 3083 is located on the cone ring 3081. A circle of column grooves 3084 is provided on a side of any cone-shaped raised ring 3083 close to the cone ring 3081. The bottom end of the jumping column 3082 is a pointed structure, and a narrow tube 3085 penetrating from top to bottom is provided at the central axis of the jumping column 3082.

[0065] The bending cover 309 is located at the upper end of the beating column 3082 , the outer wall of the bending cover 309 corresponds to the outer wall of the beating column 3082 , the outer diameter of the exhaust pipe 311 matches the inner diameter of the narrow tube 3085 , and the lower end of the exhaust pipe 311 is inserted into the narrow tube 3085 .

[0066] The upper end of the beating column 3082 is a hollow structure, and the bottom is a solid structure. Its weight can be customized according to the actual gas flow rate. It is necessary to realize that when the air pressure increases, the beating column 3082 is suspended in the air, and when the air pressure decreases, the beating column 3082 will fall. When actually removing water, the air intake valve can be automatically controlled according to this state to achieve intermittent high and low pressure air intake, thereby oscillating out the moisture in the gas. When the moisture can be easily removed, constant pressure air intake can also be used.

[0067] In an optional embodiment, a narrow ring 313 is provided at the bottom end of the inner tube 304, the diameter of the middle position of the narrow ring 313 is smaller than the diameter of the two ends, and the upper and lower ends are both transitional conical shapes, and a plurality of vortex blades 314 are fixedly installed on the inner cone surface of the bottom surface of the narrow ring 313, and the plurality of vortex blades 314 are equidistantly distributed at the same rotation angle.

[0068] The narrow opening ring 313 is a narrow opening, which mainly serves to increase the flow velocity of the airflow, and the vortex blades 314 can make the gas flowing through rotate.

[0069] In an optional embodiment, the air intake assembly 301 includes a high-pressure air pipe 3011, a fusion pipe 3012 and two dispersion pipes 3013. The dispersion pipes 3013 are fixed and connected to the outer pipe 302. The fusion pipe 3012 is fixedly connected to the two dispersion pipes 3013. The high-pressure air pipe 3011 is fixedly connected to the fusion pipe 3012.

[0070] The high-pressure air pipe 3011 needs to be connected to the air inlet end, the dispersion pipe 3013 is used to disperse the airflow into between the spiral blades 305, and an inspection port can be installed at the bottom of the fusion pipe 3012 for early drainage.

[0071] In an optional embodiment, the washing component 4 includes a washing tank 401, the exhaust pipe 311 is bent and inserted into the washing tank 401 and extends to the bottom thereof, and another high-pressure air pipe 3011 is bent and inserted into the washing tank 401 and is above the liquid level of the washing tank 401.

[0072] In an optional embodiment, a guide plate 315 is fixedly installed on the outer wall of the intermediate tube 303, and the guide plate 315 is located at the bottom of the spiral blade 305. The connection position between the dispersion tube 3013 and the outer tube 302 corresponds to the guide plate 315. The guide plate 315 is used to change the direction of the airflow so that it flows along the direction of the spiral blade 305.

[0073] In an optional embodiment, a water pump 3125 is installed on each of the drain pipes 3124 .

[0074] When in use, the alkali liquid enters the electrolytic cell and is electrolyzed to produce hydrogen and oxygen under the action of direct current. The hydrogen and oxygen need to be dehydrated. The hydrogen or oxygen pipeline is connected to the high-pressure gas pipe 3011, and the gas carrying the alkali liquid will enter the outer tube 302. The high-pressure gas will be guided by the guide plate 315 and then rotate and rise in the direction of the spiral blade 305. In this process, some larger water droplets will be thrown onto the inner wall of the outer tube 302, and then flow into the outer cone cover 3121 due to gravity. The air rising to the top will be blocked by the arc of the concentric circle 306 and return downward, and then enter between the middle tube 303 and the inner tube 304. In this process, the gas passes through multiple spoiler components 307, the gas will collide and turn back and forth, and the water particles in the gas will collide with the inner wall of the spoiler component 307, and then flow into the inner cone cover 3122 along with the spoiler component 307 and the middle tube 303.

[0075] Since there is water inside the outer cone cover 3121 and the inner cone cover 3122 is sealed by water, the water stored at the bottom is pumped out in time by the water pump 3125. However, when pumping, it is necessary to ensure that there is always water in the water storage chamber 3123 and the lower end of the inner cone cover 3122 is always inserted in the water. Therefore, the air moving to the bottom turns back upward again and enters the inner tube 304. The airflow entering the inner tube 304 will pass through multiple vortex blades 314 and the narrow ring 313. At this time, the gas flow rate increases rapidly and rises in a rotating airflow column. The water-containing gas outside the airflow column will enter the shaking assembly 308, and the airflow in the center that is basically free of water will move upward along the narrow tube 3085 until it is exhausted from the exhaust. The outer circle of the spiral airflow will enter between the beating column 3082 and the cone ring 3081 when it passes through. When passing through, the water droplets will be adsorbed on the beating column 3082. Then, with the action of the flow rate of the airflow, the beating column 3082 will rise, the flow rate of the airflow will decrease, the beating column 3082 will fall, and the water droplets adsorbed by it will fall into the inner cone cover 3122. The rising airflow will continue to flow through the bending cover 309 and enter between the middle tube 303 and the inner tube 304 again for secondary processing. The airflow between the middle tube 303 and the inner tube 304 can also bring the airflow flowing through the shaking component 308 out of the circular hole 310, until the gas circulated to the gas discharged from the narrow tube 3085 is basically free of moisture.

[0076] The gas treated by a gas-liquid separation component 3 will be washed again, and the washed gas will contain a certain amount of moisture, and can then be treated by another gas-liquid separation component 3 again.

[0077] The gas after final treatment and the separated alkali solution are respectively sent to two collecting boxes 2 and then connected to the next process.
