Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production, in particular to a filtering and impurity removal device for hydrogen production. Background Art

[0002] Hydrogen production is an important energy conversion process that can decompose water into hydrogen and oxygen, thereby providing clean, efficient and renewable energy. There are many methods for hydrogen production, such as water electrolysis, hydrothermal conversion, photocatalytic decomposition, etc. Different hydrogen production methods require different raw water, such as pure water, seawater, wastewater, etc. No matter which raw water is used, it needs to be filtered and cleaned to remove impurities such as suspended matter, organic matter, heavy metal ions, etc. These impurities will affect the efficiency and quality of hydrogen production and even damage the hydrogen production equipment.

[0003] At present, there are many commonly used filtering and impurity removal devices, such as reverse osmosis membranes, quartz sand filters, activated carbon filters, etc. Although these devices can effectively remove impurities in water, they also have some disadvantages, such as high operating costs, easy clogging, and difficult maintenance. For example, the public document with application number CN201820023922.8 discloses a quartz sand filter, which can increase the agitation of impurities in the water bath filter layer to a certain extent by fully mixing high-pressure gas with backwash water, and at the same time, the attached impurities rise in the opposite direction, thereby improving the recoil effect. However, the quartz sand filter has the problem that the medium is not easy to replace and maintain, and the impurities inside the medium cannot be effectively removed by backwash water, thereby reducing the filtering effect.

[0004] Therefore, it is necessary to develop a new type of filtering and impurity removal device for hydrogen production to improve the filtering effect and reduce the operating cost.

[0005] In view of this, a filtering and impurity removal device for hydrogen production is designed. Utility Model Content

[0053] See also Figure 1-8 The utility model provides a technical solution: a filtering and impurity removal device for hydrogen production, including a tank body 1 and a filtering mechanism 7.

[0054] The tank body 1 comprises an upper tank 11, a middle tank 12 and a lower tank 13, and the upper tank 11, the middle tank 12 and the lower tank 13 are connected in sequence from top to bottom.

[0055] The bottom inner wall of the upper tank 11 and the top inner wall of the lower tank 13 are fixedly connected with mounting rings 2, and the surfaces of the two sets of mounting rings 2 are respectively connected to the top inner wall of the middle tank 12 and the bottom inner wall of the middle tank 12 through threaded structures. Figure 2-3 Through the action of the two sets of mounting rings 2, the upper tank 11, the middle tank 12 and the lower tank 13 can be quickly disassembled and connected, so that it is convenient to clean and maintain the inside of the tank body 1, and it is also convenient to disassemble and maintain the filtering mechanism 7, which reduces the maintenance cost and improves the filtering effect.

[0056] A feed inlet 111 is integrally connected to the top of the upper tank 11 .

[0057] A discharge port 121 is integrally connected to the front side of the lower end of the middle tank 12, a plurality of groups of legs 122 are fixedly connected to the bottom of the middle tank 12, a first connecting pipe 3 is fixedly connected to the upper end of one side of the middle tank 12, a second connecting pipe 4 is fixedly connected to the lower end of one side of the middle tank 12, and an upper discharge pipe 5 is fixedly connected to the upper end of the other side of the middle tank 12.

[0058] The lower end of the first connecting pipe 3 is fixedly connected to the second connecting pipe 4 .

[0059] A backwash pipe 6 is fixedly connected to the bottom of the lower tank 13 .

[0060] Valves 8 are installed on the first connecting pipe 3 , the second connecting pipe 4 , the upper discharge pipe 5 , and the backwash pipe 6 .

[0061] The filter mechanism 7 is arranged inside the middle tank 12, and the filter mechanism 7 includes a water distribution tray 71, a carrier frame 72, a lower filter plate 73, a connecting rod 74, an upper filter plate 75 and an outer ring 76, wherein:

[0062] The water distribution tray 71 and the support frame 72 are both fixedly connected to the inner wall of the lower end of the middle tank 12, and the support frame 72 is arranged above the water distribution tray 71;

[0063] The lower filter plate 73 is connected to the top of the carrier frame 72;

[0064] The bottom of the connecting rod 74 is fixedly connected to the top of the lower filter plate 73, and the top of the connecting rod 74 is fixedly connected to the bottom of the upper filter plate 75;

[0065] The outer ring 76 is fixedly connected to the top edge of the lower filter plate 73 .

[0066] The water distribution tray 71 is horizontally located below the discharge port 121, and the support frame 72 is horizontally located above the discharge port 121. Specifically, on the one hand, the raw water input from above is discharged from the lower filter plate 73 after being filtered, so that the filtered raw water can be directly discharged through the discharge port 121, and on the other hand, a larger space can be formed between the top of the water distribution tray 71 and the lower filter plate 73 to prevent untreated raw water from contacting the water distribution tray 71, thereby improving the filtering efficiency.

[0067] The support frame 72 is an annular structure. Specifically, the support frame 72 can provide a stable support and limit function for the lower filter plate 73, the upper filter plate 75, and the outer ring 76. The annular structure can make the support frame 72 more stable and uniformly support the lower filter plate 73 and other components, and the inner side of the support frame 72 can pass liquid normally, ensuring a large flow rate.

[0068] The diameter length of the lower filter plate 73, the diameter length of the upper filter plate 75, and the outer diameter length of the outer ring 76 are adapted to the inner diameter length of the middle tank 12. Specifically, the outer surface of the upper filter plate 75, the outer surface of the lower filter plate 73, and the outer surface of the outer ring 76 are all in contact with the inner wall surface of the middle tank 12, so that a sealed state can be formed between the third component and the middle tank 12 to prevent the raw water or cleaning liquid from leaking or overflowing from the gap, and an annular storage area is formed between the top of the lower filter plate 73 and the inner side of the outer ring 76, and a medium such as quartz sand can be placed on the inner side of the outer ring 76. The filter medium can intercept suspended matter, organic matter and other macromolecular impurities in the raw water and leave them on the surface of the filter medium, so that the raw water input from the feed inlet 111 is first filtered through the upper filter plate 75, filtered twice through the filter medium, and finally filtered three times through the lower filter plate 73, effectively improving the filtering effect.

[0069] Two sets of pressure rods 112 are fixedly connected to the inner top of the upper tank 11, and the lower ends of the pressure rods 112 are pressed tightly against the top of the upper filter plate 75 by movement. Figure 2-3When the filtering mechanism 7 is installed inside the middle tank 12, the upper tank 11 can be screwed onto the top of the middle tank 12 through the mounting ring 2, so that the pressure rod 112 is pressed tightly against the top of the upper filter plate 75. The upper filter plate 75, the lower filter plate 73, the outer ring 76, and the connecting rod 74 are synchronously limited by the pressure rod 112 and the supporting frame 72, thereby improving the stability of the upper filter plate 75, the lower filter plate 73, the outer ring 76, and the connecting rod 74 inside the middle tank 12.

[0070] A plurality of mounting holes 711 are provided in the water distribution tray 71, and a nozzle 712 is connected to the mounting hole 711 through a threaded structure. Figure 6-8 The lower end of the nozzle 712 is an external threaded pipe structure. Through a plurality of groups of nozzles 712, the cleaning water can be evenly sprayed on the lower filter plate 73, thereby realizing backwashing of the filter medium and reducing the maintenance frequency.

[0071] Specifically, when filtering raw water, the four groups of valves 8 on the first connecting pipe 3, the second connecting pipe 4, the upper discharge pipe 5, and the backwash pipe 6 can be closed, the feed port 111 is connected to the raw water input pipeline, and the discharge port 121 is connected to the output pipeline. Both the raw water input pipeline and the output pipeline can be provided with pipe valves to achieve pipeline passage closure, so as to ensure the relative sealing inside the tank body 1, so that the raw water input from the feed port 111 is filtered three times through the upper filter plate 75, the filter medium, and the lower filter plate 73, and finally the filtered water is discharged from the discharge port 121.

[0072] Specifically, when backwashing the inside of the tank body 1, the feed port 111 and the discharge port 121 can be blocked, the valve 8 on the first connecting pipe 3 is closed first, and the three groups of valves 8 on the upper discharge pipe 5, the backwashing pipe 6, and the second connecting pipe 4 are opened, and the cleaning liquid is input into the lower tank 13 through the second connecting pipe 4, and then the valve 8 on the second connecting pipe 4 is closed, and the backwashing pipe 6 is connected to the high-pressure water pump. The high-pressure cleaning water is sprayed upward onto the lower filter plate 73 through several groups of nozzles 712, and as the cleaning water and the cleaning liquid are mixed, the cleaning liquid quickly fills the entire tank body 1, thereby realizing backwashing of the filter medium, and the sewage in the cleaning process can be discharged through the upper discharge pipe 5.

[0073] Specifically, when backwashing the inside of the tank body 1 is performed, the first connecting pipe 3 may also be connected to a high-pressure water pump to flush the upper filter plate 75 .

[0074] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
