Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology, and in particular to a hydrogen purification device. Background Technology

[0002] Hydrogen is a gas that is highly flammable at room temperature and pressure. It has the smallest relative molecular mass and strong reducing properties. During the production of hydrogen, many impurities may be present, which brings many inconveniences to the subsequent use and experiments of hydrogen.

[0003] However, existing hydrogen purification devices are quite expensive to manufacture to increase purity, using methods such as palladium membrane purification and pressure swing adsorption, which increases the relative cost for downstream users. Therefore, it is necessary to propose a hydrogen purification device to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to solve at least one of the technical problems existing in the prior art, and to provide a hydrogen purification device that can solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen purification device, comprising a first processing box, a first condensing plate disposed inside the first processing box, a first vent hole being formed on the outer surface of the first condensing plate, a second condensing plate disposed inside the first processing box, a second vent hole being formed on the outer surface of the second condensing plate, a second water tank disposed on the lower surface of the first processing box, a water level pipe being fixedly connected to the right side of the second water tank, a connecting pipe being fixedly connected to the front side of the second water tank, a limiting post being fixedly connected to the front side of the connecting pipe, a threaded rod being rotatably connected inside the limiting post, a handle being fixedly connected to the upper surface of the threaded rod, a slider being threadedly connected to the outer surface of the threaded rod, a sliding groove being formed on the outer surface of the slider, a limiting strip being fixedly connected inside the limiting post, and the outer surface of the limiting strip being slidably connected to the inside of the sliding groove.

[0006] Preferably, a second processing box is fixedly connected to the right end of the first processing box, and a feed inlet is fixedly connected to the right end of the second processing box.

[0007] Preferably, a first water tank is fixedly connected to the lower surface of the second processing tank, and a water pump is fixedly connected to the left side of the first water tank.

[0008] Preferably, the left side of the first water tank is fixedly connected to the input end of the water pump.

[0009] Preferably, the output end of the water pump is fixedly connected to a water delivery pipe, and the end of the water delivery pipe away from the water pump is fixedly connected to a fixing frame.

[0010] Preferably, a water spray head is fixedly connected to the lower surface of the fixing frame, and a filter plate is provided inside the left side of the second treatment box.

[0011] Preferably, a discharge port is fixedly connected to the left end of the first processing box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this hydrogen purification device, hydrogen enters the first processing chamber. An external device cools both the first and second condensing plates to a low temperature. The hydrogen, blocked by the second condensing plate, passes through a second vent and blows onto the surface of the first condensing plate. Due to the different angles of the vents on the first and second condensing plates, the hydrogen fully contacts the first condensing plate. As it passes the next baffle, its direction changes, ensuring full contact between the first and second condensing plates. Water vapor in the hydrogen condenses into a liquid under the cooling effect of the first condensing plate and slides down the bottom of the first processing chamber into a second water tank. By observing the water level pipe, once the condensed water exceeds a certain mark, rotating the handle causes the slider to slide upwards inside a limiting post via the threaded drive of the threaded rod and slider. The condensed water in the second water tank is discharged through the connecting pipe at the bottom of the limiting post, effectively removing moisture from the hydrogen at low cost.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a hydrogen purification device, including a first processing box 1, a first condensing plate 16 is provided inside the first processing box 1, a first vent hole 15 is opened on the outer surface of the first condensing plate 16, a second condensing plate 17 is provided inside the first processing box 1, a second vent hole 18 is opened on the outer surface of the second condensing plate 17, a second water tank 12 is provided on the lower surface of the first processing box 1, a water level pipe 14 is fixedly connected to the right side of the second water tank 12, a connecting pipe 11 is fixedly connected to the front of the second water tank 12, a limiting post 10 is fixedly connected to the front of the connecting pipe 11, a threaded rod 9 is rotatably connected inside the limiting post 10, a handle 8 is fixedly connected to the upper surface of the threaded rod 9, a slider 19 is threadedly connected to the outer surface of the threaded rod 9, a sliding groove 20 is opened on the outer surface of the slider 19, a limiting strip 21 is fixedly connected inside the limiting post 10, and the outer surface of the limiting strip 21 is slidably connected to the inside of the sliding groove 20.

[0026] During operation, hydrogen gas, after carbon dioxide removal in the second processing chamber 4, enters the first processing chamber 1. An external device cools the second condenser plate 17 and the first condenser plate 16, bringing them to a low temperature. Blocked by the second condenser plate 17, the hydrogen gas passes through the second vent hole 18 and blows onto the surface of the first condenser plate 16. Due to the different positions and angles of the holes in the first and second condenser plates 16 and 17, the hydrogen gas fully contacts the first condenser plate 16. Upon passing through the next baffle, the hydrogen gas changes direction, ensuring that the first condenser plate 16 and the second condenser plate 17 remain in contact. The condenser plate 17 is in full contact with the hydrogen gas. The water vapor contained in the hydrogen gas is condensed into a liquid state under the cooling effect of the first condenser plate 16. It eventually slides into the second water tank 12 through the bottom of the first treatment box 1. By observing the water level tube 14, after the condensed water exceeds a certain scale, the handle 8 is rotated. The threaded transmission between the threaded rod 9 and the slider 19 causes the slider 19 to slide upward inside the limiting post 10. The bottom of the limiting post 10 is connected to the connecting pipe 11, and the condensed water in the second water tank 12 is discharged, which plays a role in fully removing the moisture from the hydrogen gas.

[0027] The right end of the first processing box 1 is fixedly connected to the second processing box 4, and the right end of the second processing box 4 is fixedly connected to the feed inlet 13.

[0028] During operation, hydrogen gas is introduced through the feed inlet 13 for processing.

[0029] The lower surface of the second processing tank 4 is fixedly connected to the first water tank 6, and the left side of the first water tank 6 is fixedly connected to the water pump 7.

[0030] During operation, the water pump 7 is used to transport the lime water in the first water tank 6 to the spray head 22.

[0031] The left side of the first water tank 6 is fixedly connected to the input end of the water pump 7.

[0032] During operation, the first water tank 6 serves to store lime water.

[0033] The output end of the water pump 7 is fixedly connected to a water delivery pipe 5, and the end of the water delivery pipe 5 away from the water pump 7 is fixedly connected to a fixing bracket 3.

[0034] During operation, the fixing bracket 3 serves to fix the water spray head 22.

[0035] A water spray head 22 is fixedly connected to the lower surface of the fixed frame 3, and a filter plate 23 is installed inside the left side of the second treatment box 4.

[0036] During operation, the filter plate 23 filters out fine calcium carbonate particles from the hydrogen gas.

[0037] The left end of the first processing box 1 is fixedly connected to the discharge port 2.

[0038] During operation, hydrogen gas is discharged through outlet 2.

[0039] Working principle: Hydrogen gas is introduced into the second processing tank 4 through the feed inlet 13. The water pump 7 is started, spraying the lime water inside the first water tank 6 through the spray nozzle 22 to form a water mist. This mist reacts with the carbon dioxide in the hydrogen gas to form calcium carbonate, removing the carbon dioxide. The hydrogen gas is then filtered through the filter plate 23, preventing fine calcium carbonate particles from entering the next filtration device and affecting hydrogen usage. The hydrogen gas then enters the first processing tank 1. An external device cools the second condenser plate 17 and the first condenser plate 16 to a low temperature. Blocked by the second condenser plate 17, the hydrogen gas passes through the second vent 18 and blows onto the surface of the first condenser plate 16. Due to the interaction between the first condenser plate 16 and the second condenser plate... The holes in plate 17 are positioned at different angles, ensuring that the hydrogen gas is in complete contact with the first condensing plate 16. When passing through the next baffle, the direction is changed, allowing the first condensing plate 16 and the second condensing plate 17 to fully contact the hydrogen gas. The water vapor contained in the hydrogen gas condenses into a liquid state under the cooling effect of the first condensing plate 16, and finally slides into the second water tank 12 through the bottom of the first processing box 1. By observing the water level tube 14, after the condensed water exceeds a certain scale, the handle 8 is rotated, and the threaded transmission between the threaded rod 9 and the slider 19 causes the slider 19 to slide upward inside the limiting post 10. The bottom of the limiting post 10 is connected to the connecting pipe 11, and the condensed water in the second water tank 12 is discharged, which effectively removes the moisture from the hydrogen gas.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
