[0052] In existing technology, hydrogen is cooled, replenished with water, and demisted by sequentially connected cooling tanks, dripping tanks, and demisting tanks, respectively. However, these sequentially connected cooling tanks, dripping tanks, and demisting tanks occupy a large amount of space.

[0053] For example, in the cooling and replenishment process, the liquid formed by the condensation of hydrogen gas refers to the liquid formed after the condensation of impurities in the hydrogen gas containing impurities. These impurities include substances such as water and alkali.

[0054] For example, in one hydrogen manufacturing process, hydrogen is separated from the hydrogen-alkali mixture generated by the electrolyzer into hydrogen and alkali solution containing alkali mist by a separator. The hydrogen containing alkali mist needs to be cooled, replenished with dripping, and demisted to reduce the temperature and ensure gas purity. In this example, the liquid formed by the cooling and replenishment of hydrogen is an alkaline solution.

[0055] To address the aforementioned problems, this application provides a counter-current drip-replenishing and demisting integrated tank, comprising: a tank body; an inner liner disposed within the tank body, which sequentially divides the tank body from top to bottom into an air inlet chamber, a cooling chamber, and a liquid collection chamber, with the lower part of the inner liner communicating with the liquid collection chamber; a cooling pipe located within the cooling chamber and communicating with the air inlet chamber and the liquid collection chamber, wherein the cooling chamber is used to cool hydrogen gas entering the cooling pipe through the air inlet chamber, and the liquid collection chamber is used to collect the liquid formed by the condensation of hydrogen gas; and a demisting component disposed within the inner liner, which is used to demist the hydrogen gas entering the inner liner from the liquid collection chamber, and the inner liner is used to discharge the demisted hydrogen gas from the tank body. In use, the cooling chamber cools the cooling pipe and the inner liner to cool the hydrogen gas flowing through the cooling pipe and replenish the hydrogen gas flowing through the inner liner; the demisting component within the inner liner demistates the hydrogen gas; and the liquid formed by the condensation of hydrogen gas is collected through the liquid collection chamber. The counter-current drip replenishment and demisting integrated tank provided in this application occupies less space when cooling, replenishing, and demisting hydrogen compared with the prior art.

[0056] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0057] This application provides a counter-current type drip-replenishing and demisting integrated tank, referring to... Figure 2 The system includes a tank body 100, an inner liner 200, a cooling pipe 300, and a demister 400. The inner liner 200 is disposed within the tank body 100, dividing the tank body 100 from top to bottom into an air inlet chamber 110, a cooling chamber 120, and a liquid collection chamber 130. The lower part of the inner liner 200 communicates with the liquid collection chamber 130. The cooling pipe 300 is located within the cooling chamber 120 and connects the air inlet chamber 110 and the liquid collection chamber 130. The cooling chamber 120 is used to cool the hydrogen gas entering the cooling pipe 300 through the air inlet chamber 110, and the liquid collection chamber 130 is used to collect the liquid formed by the condensation of the hydrogen gas. The demister 400 is disposed within the inner liner 200 and is used to demist the hydrogen gas entering the inner liner 200 from the liquid collection chamber 130. The inner liner 200 is used to discharge the demisted hydrogen gas from the tank body 100.

[0058] When using a counter-current drip-replenishing and demisting integrated tank to cool, replenish, and demist hydrogen, the cooling chamber 120 cools the cooling pipe 300 and the inner liner 200 to cool the hydrogen flowing through the cooling pipe 300 and replenish the hydrogen flowing through the inner liner 200; a demisting component 400 is installed in the inner liner to demist the hydrogen; and the liquid formed by the condensation of hydrogen is collected through the liquid collection chamber 130. Compared with the prior art, the counter-current drip-replenishing and demisting integrated tank provided in this application occupies less space when cooling, replenishing, and demisting hydrogen.

[0059] For example, the tank 100 may be an all-metal structure (e.g., made of steel or aluminum); the tank 100 may also be a structure in which a metal liner is wrapped with a composite material such as glass fiber, aromatic polyamide, or carbon fiber; the tank 100 may also be a structure in which there is no liner, such as a composite material such as glass fiber, aromatic polyamide, or carbon fiber.

[0060] In the specific implementation of this application, the inner liner 200 is made of a heat-conducting material to facilitate heat exchange between the cooling chamber 120 and the interior of the inner liner 200. The cooling chamber 120 removes heat from the inner liner, which is then used to further condense and drip hydrogen impurities flowing through the inner liner 200, i.e., for replenishment. The inner liner 200 can be a container with its opening facing downwards, or it can be a pipe.

[0061] For example, the inner liner can be made of steel, aluminum alloy, or copper alloy.

[0062] For example, refer to Figure 1 and Figure 2 A connecting seat 140 can be provided on the tank body 100. The connecting seat 140 is used to connect and fix to the installation position by bolts.

[0063] In some implementations, refer to Figure 2 The counter-current drip-replenishing and demisting integrated tank also includes two partitions 210, which are respectively disposed at the upper and lower parts of the inner liner 200 and connected to the inner wall of the tank body 100. The partitions 210 are used to divide the space between the inner liner 200 and the tank body 100 into an air inlet chamber 110, a cooling chamber 120 and a liquid collection chamber 130. The two ends of the cooling pipe 300 are respectively inserted into the two partitions 210.

[0064] The tank 100 and the inner liner 200 between the two partitions 210 together form a cooling chamber 120. The tank 100 located above the inner liner 200, the partitions located above the inner liner 200, and the upper part of the inner liner 200 together form an air intake chamber 110. The tank 100 located below the inner liner 200, the partitions 210 located below the inner liner 200, and the lower part of the inner liner 200 together form a liquid collection chamber 130.

[0065] For example, the inner liner 200 may be disposed on one side inside the tank 100 to form a cooling chamber on the other side inside the tank.

[0066] For example, the periphery of the portion of the cooling pipe 300 inserted into the separator 210 is welded to the separator to form a seal around the insertion location and to fix the cooling pipe 300.

[0067] For example, the portion of the cooling pipe 300 inserted into the separator 210 may also be provided with a seal to seal the periphery of the insertion location.

[0068] In some implementations, refer to Figure 2 The separator 210 is arranged around the periphery of the inner liner 200 so that the cooling chamber 120 forms an annular cavity. The annular cavity feature of the cooling chamber facilitates cooling of the inner liner 200 from all sides, so that the periphery of the inner wall of the inner liner 200 is at a lower temperature, thereby improving the condensation efficiency and effect of the cooling chamber 120 on impurities in the hydrogen gas in the inner liner 200, which also improves the efficiency and effect of drip replenishment.

[0069] In some implementations, refer to Figure 2There are multiple cooling pipes 300, which are arranged sequentially and at intervals around the periphery of the inner liner 200. Hydrogen gas enters the multiple cooling pipes 300 through the inlet chamber 110 and is simultaneously cooled by the cooling chamber 120. Compared with a single long-path pipeline design, this design facilitates sufficient heat exchange during hydrogen cooling, improves cooling efficiency, and ensures heat exchange effect. It also helps to reduce gas flow resistance to a certain extent and lowers the hydrogen processing pressure requirement. This benefits both the safety of production or processing operations and the reduction of compressor energy consumption, thus saving energy.

[0070] The cooling pipe 300 can be a straight pipe, which has the advantage of low resistance to the flow of hydrogen.

[0071] The cooling pipe 300 can also be a spiral pipe, which has the advantage of good cooling effect on hydrogen.

[0072] The cooling pipe 300 can also be a coil that spirals around the circumference of the inner liner 200.

[0073] In specific implementations, this application may also use at least two of the following: a straight pipe, a spiral pipe, or a coil that winds around the circumference of the inner liner 200.

[0074] Exemplary quality, reference Figure 2 One end of the multiple cooling pipes 300 is evenly distributed on the upper partition, which facilitates the even distribution of hydrogen in the air intake chamber 110, so that the hydrogen flows evenly through the multiple cooling pipes 300; the lower ends of the multiple cooling pipes 300 are evenly distributed on the lower partition 210, which facilitates the more even distribution of airflow from the lower end of the inner liner 200 into the inner liner 200, and facilitates the more even replenishment and demisting of hydrogen inside the inner liner 200.

[0075] In some implementations, refer to Figure 2 and Figure 3 The counter-current drip-replenishing and demisting integrated tank also includes an exhaust pipe 500. The upper part of the inner liner 200 has an exhaust port 221. The exhaust pipe 500 is inserted into the tank body 100, and a portion of the exhaust pipe 500 extends into the air inlet chamber 110 to communicate with the inner liner 200 via the exhaust port 221. This facilitates the discharge of treated hydrogen gas through the exhaust pipe 500.

[0076] The vent pipe 500 is sealed around the perimeter of the tank 100 to prevent leakage of liquid and / or gas from the tank through the perimeter of the insertion point.

[0077] For example, the exhaust pipe 500 is connected to the exhaust port 221 by threads.

[0078] For example, exhaust pipe 500 is welded to exhaust port 221.

[0079] In some implementations, refer to Figure 2 The inner liner 200 has a protrusion 220 on its upper part, with the top of the protrusion 220 facing the air inlet chamber 110, and the exhaust port 221 located on the top of the protrusion 220. The protrusion 220 provides a constricted variable diameter channel, which is beneficial for secondary droplet separation of hydrogen.

[0080] For example, the protrusion 220 can be an inverted funnel, which is a funnel with its wide opening facing downwards.

[0081] In some implementations, refer to Figure 2 The demisting component 400 is a demisting mesh with a porosity greater than 98%, which helps to improve the interception effect of fog. And / or, the demisting component 400 is located in the middle of the inner liner 200, which facilitates the demisting work after sufficient hydrogen replenishment, thus ensuring the effectiveness of replenishment and demisting.

[0082] For example, the demister mesh is a nickel wire mesh.

[0083] In some implementations, refer to Figures 1 to 3 The tank body 100 has a medium inlet 121 and a medium outlet 122, both of which are connected to the cooling chamber 120. The medium inlet 121 is located above the medium outlet 122. The medium inlet 121 and the medium outlet 122 facilitate the flow of medium into and out of the cooling chamber 120, allowing the flowing medium to remove heat from the cooling pipes or inner tank.

[0084] For example, the counter-flow drip-replenishing and demisting integrated tank can be connected to a media circulation supply system during use. The media flows into the cooling chamber 120 through the media inlet 121, flows from bottom to top in the cooling chamber 120, and then flows out of the cooling chamber 120 through the media outlet 122 to ensure sufficient heat exchange. Water is a commonly used media.

[0085] For example, a medium inlet connector 1211 can be connected to the medium inlet 121 by means of threaded connection or welding, so as to facilitate the connection of the medium inlet 121 to the pipeline supplying the cooling medium via the medium inlet connector 1211. Alternatively, a medium outlet connector 1221 can be connected to the medium outlet 122 by means of threaded connection or welding, so as to facilitate the connection of the medium outlet 122 to the cooling medium return pipeline via the medium outlet connector 1221.

[0086] In some embodiments, the tank 100 has an air inlet 111 that communicates with the air inlet chamber 110. And / or, the tank 100 has a drain outlet 131 that communicates with the liquid collection chamber 130. The air inlet 111 facilitates the introduction of hydrogen gas to be processed into the air inlet chamber 110; the drain outlet 131 facilitates the discharge of condensed liquid in the liquid collection chamber 130 to the outside of the tank 100.

[0087] For example, the top of the tank 100 is an arc shape with a high center and a low perimeter, and the air inlet 111 is located in the middle of the top of the tank 100 to facilitate the uniform introduction of hydrogen into the air inlet chamber 110; the bottom of the tank 100 is an arc shape with a low center and a high perimeter, and the liquid outlet 131 is located in the middle of the bottom of the tank 100 to facilitate the more thorough discharge of condensate.

[0088] For example, an inlet connector 1111 can be connected to the inlet 111 by means of threaded connection or welding to facilitate connection of the inlet 111 to the hydrogen supply pipeline. A drain connector 1311 can be connected to the drain port 131 by means of threaded connection or welding to facilitate connection of the drain port 131 to the condensate discharge pipeline.

[0089] In some embodiments, the counter-current drip-replenishing and demisting integrated tank also includes a liquid level detection element, which is installed on the tank body 100 and is used to detect the liquid level in the collection chamber 130. A drain valve is installed on the drain port 131. When the liquid level is greater than or equal to a preset liquid level, the drain valve opens to drain the liquid in the collection chamber 130. The liquid level detection element and the drain valve are used to automatically discharge and periodically drain the condensate. Each discharge action helps to partially discharge the condensate while retaining a portion of the condensate in the collection chamber 130, preventing hydrogen gas from flowing out from the drain port 131.

[0090] For example, the drain valve is a normally closed electrically controlled valve. It opens when energized and closes when de-energized. A normally open contact of a contactor is connected in series in the power supply circuit of the drain valve, controlling its energization or de-energization. The level detection element is a level switch. The level switch closes when the level is greater than or equal to a preset level and opens when the level is less than the preset level. The level switch is connected in series in the power supply circuit of an intermediate relay coil, controlling its energization or de-energization. A set of normally open contacts of the intermediate relay is connected in series in the power supply circuit of the contactor coil, controlling its energization or de-energization by opening and closing the intermediate relay's normally open contacts.

[0091] For example, a float valve can also be used as a level detection device and a drain valve. A float valve includes a float and a valve that is linked to the float. The float is the level detection device, and the valve linked to the float is the drain valve.
