Description

Technical Field

[0001] This application relates to the technical field of gas purification, and in particular, to a gas scrubbing tank for gas purification. Background Art

[0002] In the existing electrolyzed water process, after the electrolysis of water in the electrolysis equipment is completed, the gas and the waste liquid are discharged together, forming a gas carrying the waste liquid. At this time, it is necessary to use the gas purification system in the electrolysis equipment to purify the discharged gas.

[0003] Currently, common gas purification systems mainly use gas-liquid separation equipment. After the gas is discharged into the gas-liquid separation equipment, the gas and the waste liquid are separated to achieve gas purification. However, after the gas carrying the waste liquid passes through the gas-liquid separation equipment, the separated gas needs to be washed by a washing equipment. And the separated waste liquid needs to be recycled to the electrolysis equipment for reuse. However, since electrolyzed water consumes water, the water content of the waste liquid decreases, which will cause the concentration of the waste liquid to change. Therefore, it is necessary to supplement water to ensure that the concentration of the waste liquid remains stable. At the same time, supplementing water is also to supplement the consumed water to ensure that there is enough water for electrolysis. This requires the use of a water replenishing equipment to replenish water into the recycled waste liquid.

[0004] This makes it necessary to additionally set up a washing equipment and a water replenishing equipment to further process the gas and the waste liquid in addition to the gas-liquid separation equipment in the gas purification system. This makes the component equipment of the gas purification system more, and thus the equipment cost of the gas purification system is higher. Summary of the Invention

[0005] This application provides a gas scrubbing tank for gas purification, and its purpose is to simultaneously realize three functions of gas-liquid separation, gas washing and water replenishment through the gas scrubbing tank. Thus, the gas scrubbing tank can be used as a gas-liquid separation equipment, a gas washing equipment and a water replenishing equipment at the same time, which can reduce the equipment cost of the gas purification system.

[0006] A gas scrubbing tank for gas purification provided by this application adopts the following technical solution:

[0007] A gas scrubbing tank for gas purification includes a tank body. A gas inlet, a gas outlet, a water replenishing inlet and a waste liquid outlet are opened on the tank body; A gas pipe is further arranged in the tank body. One end of the gas pipe is connected to the inner side wall of the tank body, and the other end is closed. And the gas pipe is communicated with the gas inlet. A plurality of micropores are opened on the outer side wall of the gas pipe; A water replenishing pipe is further arranged in the tank body. One end of the water replenishing pipe is connected to the inner side wall of the tank body, and the other end is closed. And the water replenishing pipe is communicated with the water replenishing inlet. A spraying assembly is arranged on the water replenishing pipe. The spraying assembly is located above the gas pipe in the vertical direction.

[0008] By adopting the above technical solution, first, a gas inlet is provided on the tank body, which enables the input of the gas of the waste liquid to be separated into the tank body. A gas pipe is arranged in the tank body, and the gas pipe is communicated with the gas inlet. A number of micropores are provided on the gas pipe. The provision of the micropores enables the gas to discharge from the gas pipe through the micropores, while the waste liquid remains in the gas pipe, thus realizing the preliminary separation of gas and liquid.

[0009] On this basis, since a gas outlet is provided on the tank body, the separated gas can be discharged, thus meeting the function of gas-liquid separation.

[0010] Secondly, a water replenishment inlet is provided on the tank body, which enables the input of normal temperature pure water into the tank body for water replenishment. A water replenishment pipe and a spraying component are arranged in the tank body. The water replenishment pipe is communicated with the water replenishment inlet, and the spraying component is communicated with the water replenishment pipe. Thus, the normal temperature pure water input into the tank body will be input into the spraying component by the water replenishment pipe, and the spraying component sprays out the normal temperature pure water. Since the spraying component is located above the gas pipe, the gas discharged from the gas pipe will rise in the direction of the spraying component. On the contrary, the normal temperature pure water sprayed out by the spraying component will naturally fall in the direction of the gas pipe. In this process, the gas and the normal temperature pure water are in countercurrent contact, and the normal temperature pure water washes the gas to remove the waste liquid. This can meet the function of gas washing.

[0011] On this basis, since a waste liquid outlet is provided on the tank body, the normal temperature pure water after washing the gas can be discharged from the waste liquid outlet. At this time, the normal temperature pure water is mixed with a part of the waste liquid, which enables the discharged normal temperature pure water to flow back to the electrolysis equipment. On the one hand, the waste liquid is recycled to reduce the consumption of the waste liquid; on the other hand, the consumed water can be replenished to ensure the waste liquid concentration and the water volume.

[0012] Therefore, through the cooperation of the tank body, the gas pipe, the water replenishment pipe and the spraying component, the three functions of gas washing, gas washing and water replenishment can be realized. This enables the gas washing tank of the present application to be used as a gas-liquid separation device, a gas washing device and a water replenishment device at the same time, which can reduce the equipment cost of the gas purification system.

[0013] Optionally, a washing tray is further arranged in the tank body. A washing groove is provided on the upper side of the washing tray. The gas pipe is connected to the washing tray, and one end of the gas pipe extends into the washing groove.

[0014] By adopting the above technical solution, a washing groove is provided on the washing tray, and one end of the gas pipe extends into the washing groove. Since the washing groove on the washing tray has the function of storing water, when the spraying assembly above the gas pipe works, the spraying assembly will spray normal temperature pure water into the washing groove. At this time, a part of the normal temperature pure water can be stored in the washing groove, and the normal temperature pure water submerges the gas pipe. Based on such a structural arrangement, when the gas pipe discharges gas, the gas will directly enter the normal temperature pure water stored in the washing groove, which will form tiny gas microbubbles in the normal temperature pure water, thereby increasing the contact area between the gas and the normal temperature pure water and improving the gas washing effect.

[0015] Optionally, a drain hole is provided on the side wall of the washing tray, and the drain hole communicates with the washing groove.

[0016] By adopting the above technical solution, with the opening of the drain hole, after a part of the normal temperature pure water is stored in the washing tray, the drain hole can discharge the used normal temperature pure water from the washing groove, so that the used normal temperature pure water can flow into the tank body to realize the collection of the used normal temperature pure water.

[0017] Optionally, a jacket tray is further provided in the tank body, and overflow plates are provided on both opposite sides of the jacket tray; a jacket groove is provided on the upper side of the jacket tray, the jacket groove penetrates the jacket tray along the interval direction of the two overflow plates, and the overflow plate closes one side corresponding to the jacket groove; the washing tray is arranged in the jacket groove, and the drain hole communicates with the jacket groove, and the upper side surface of the overflow plate is located above the drain hole.

[0018] By adopting the above technical solution, a jacket groove is provided on the jacket tray, and the jacket groove realizes the installation of the washing tray. The setting of the overflow plate makes a water storage interlayer capable of storing normal temperature pure water formed between the side wall of the overflow plate facing the washing tray, the two inner side walls of the jacket groove corresponding to the washing tray, and the corresponding side wall of the washing tray. Among them, the setting of the overflow plate is to limit the liquid level height in the water storage interlayer. When the spraying assembly works continuously, the liquid level height in the water storage interlayer gradually increases. When the liquid level height exceeds the upper side surface of the overflow plate, the excess normal temperature pure water overflows into the tank body at this time.

[0019] Through such a structural arrangement, a normal temperature pure water pool with a constant liquid level height can be formed in the washing tray and the jacket tray, which can ensure that the gas discharged from the gas pipe always passes through the normal temperature pure water pool with a constant liquid level height, which makes the gas pressure stable and the washing effect can also be kept stable. Since the gas washing tank of the present application is used to treat the gas discharged from electrolyzed water, the balance of the gas pressure is crucial, because the gas and oxygen in the electrolysis equipment are separated by a diaphragm, and it is necessary to control the pressure difference on both sides of the diaphragm to be stable to avoid the increase in the oxygen content in the gas due to the pressure difference of the diaphragm.

[0020] Optionally, a plurality of combing grooves are formed on a side of the overflow plate facing the washing disk, the combing grooves penetrate the washing disk, and the plurality of combing grooves are sequentially spaced apart along the width direction of the jacket groove.

[0021] By adopting the above technical solution, the comb groove is opened, so that when the liquid level in the water storage interlayer exceeds the bottom of the comb groove, the room temperature pure water can overflow into the tank body through the comb groove. Since a plurality of comb grooves are arranged in sequence along the width direction of the jacket groove, the overflow plate has a comb-shaped structure, which enables the room temperature pure water in the water storage interlayer to be quickly replaced and evenly overflow into the tank body.

[0022] Optionally, the spray assembly includes a plurality of spray pipes, which are arranged in sequence at intervals along the length direction of the water supply pipe and are arranged parallel to each other, and the spray pipes are connected to the water supply pipe; a plurality of nozzles are arranged on the lower side of the spray pipe, which are arranged in sequence at intervals along the length direction of the corresponding spray pipe.

[0023] By adopting the above technical solution, the spray assembly can evenly spray room temperature pure water onto the gas pipe through the setting of several spray pipes and several spray heads, thereby improving the uniformity of contact between the gas discharged from the gas pipe and the room temperature pure water, ensuring consistent washing effect of the gas at various locations.

[0024] Optionally, the gas pipe is made of silicon carbide material.

[0025] By adopting the above technical solution, since the gas pipe is made of silicon carbide material, the gas pipe has good strength. At the same time, after the gas pipe separates the gas and the waste liquid, the gas pipe made of silicon carbide can penetrate the waste liquid out of the gas pipe, so after the gas washing is completed, the remaining waste liquid can also be discharged into the tank body.

[0026] Optionally, the tank body is also provided with a waste liquid inlet.

[0027] By adopting the above technical solution, the waste liquid inlet is opened, so that the gas discharged from the electrolytic equipment and the waste liquid settled in the waste liquid can be directly discharged into the tank body, and the small amount of gas contained in the waste liquid entering the tank body can automatically overflow, which can achieve the separation of gas in the waste liquid.

[0028] Optionally, the tank body is also provided with a waste liquid replenishment inlet.

[0029] By adopting the above technical solution, the waste liquid replenishing inlet is opened, and waste liquid can be added into the tank body to adjust the concentration of the waste liquid so that the concentration of the waste liquid meets the requirements of reuse.

[0030] Optionally, a liquid level meter is provided in the tank body.

[0031] By adopting the above technical solution, the liquid level component is used to detect the height of the mixed liquid of waste liquid and normal temperature pure water in the tank, which is convenient for discharging the waste liquid in time.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. Through the cooperation of the tank body, the gas pipe, the water supply pipe and the spraying assembly, the present application can realize three functions of gas-liquid separation, gas washing and water supply. This enables the gas washing tank of the present application to be used as a gas-liquid separation device, a gas washing device and a water supply device at the same time, which can reduce the equipment cost of the gas purification system.

[0034] 2. Through the setting of the washing tray, when the gas is discharged from the gas pipe, the gas will directly enter the normal temperature pure water stored in the washing tank, which will form tiny gas microbubbles in the normal temperature pure water, thereby increasing the contact area between the gas and the normal temperature pure water and improving the gas washing effect.

[0035] 3. Through the setting of the jacket tray, a normal temperature pure water pool with a constant liquid level height can be formed in the washing tray and the jacket tray, which can ensure that the gas discharged from the gas pipe always passes through the normal temperature pure water pool with a constant liquid level height, so that the pressure of the gas remains stable and the washing effect can also be kept stable.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] The following will be described in further detail with reference to the Figure 1 - attached Figure 3 drawings to the present application.

[0041] A gas washing tank for gas purification, referring to Figure 1, including a tank body 1, the axial direction of the tank body 1 is arranged horizontally, two brackets are arranged on the lower side of the tank body 1, and the two brackets are arranged at intervals along the axial direction of the tank body 1.

[0042] Refer to Figure 1 and Figure 2 , a gas inlet 11 is provided at one axial end of the tank body 1, and a gas outlet 12 is provided on the upper side of the tank body 1. Through the gas inlet 11, the gas of the waste liquid to be separated can be introduced into the tank body 1, and the gas outlet 12 discharges the separated and washed gas.

[0043] Refer to Figure 2 and Figure 3 , a washing tray 2 is arranged in the tank body 1, and the bottom of the washing tray 2 is connected to the inner wall of the tank body 1. A gas pipe 3 is arranged between the washing tray 2 and the inner side wall of the tank body 1. One end of the gas pipe 3 is connected to the inner side wall of the tank body 1, the other end is connected to the washing tray 2, and one end of the gas pipe 3 is communicated with the gas inlet 11, the other end is closed, and a plurality of micropores are opened on the gas pipe 3. In this embodiment, the gas pipe 3 is made of silicon carbide, and the diameter of the micropores opened on the gas pipe 3 is 3 microns.

[0044] The gas of the waste liquid to be separated is discharged into the gas pipe 3 through the gas inlet 11, and then the gas can be discharged from the gas pipe 3 through the micropores on the gas pipe 3. And, since the gas pipe 3 is made of silicon carbide and the diameter of the micropores opened on the gas pipe 3 is 3 microns, the 3-micron pore diameter ensures that the gas can pass through, while the waste liquid carried in the gas cannot pass through, which can achieve the preliminary separation of gas and liquid; and the intercepted waste liquid will penetrate from the bottom of the gas pipe 3 to the outside of the gas pipe 3, which can prevent the waste liquid from blocking the gas pipe 3 due to excessive amount.

[0045] In this embodiment, the diameter of the gas pipe 3 is 5 cm, the wall thickness is 0.2 cm, the length is 50 cm to 100 cm, and the porosity is greater than 70%. The structural setting and material selection of the gas pipe 3 ensure that the gas can be quickly discharged from the gas pipe 3, thereby improving the gas washing efficiency.

[0046] Refer to Figure 2 and Figure 3 , a water replenishing inlet 13 is provided at one end of the tank body 1 along its own axial direction away from the gas inlet 11, and the opening of the water replenishing inlet 13 can replenish normal temperature pure water into the tank body 1.

[0047] Refer to Figure 2 and Figure 3 , a water replenishing pipe 4 is also arranged between the washing tray 2 and the inner side wall of the tank body 1. The axial direction of the water replenishing pipe 4 is arranged along the axial direction of the tank body 1. One end of the water replenishing pipe 4 is connected to the inner side wall of the tank body 1, the other end is connected to the washing tray 2, and the water replenishing pipe 4 is communicated with the water replenishing inlet 13.

[0048] Refer to Figure 2 andFigure 3 A spray component 5 is provided on the water replenishing pipe 4. The spray component 5 includes a plurality of spray pipes 51. The plurality of spray pipes 51 are arranged at intervals in sequence along the axial direction of the water replenishing pipe 4. The axial direction of the spray pipe 51 is arranged horizontally, and the axial direction of the spray pipe 51 is perpendicular to the axial direction of the water replenishing pipe 4. The middle part of the spray pipe 51 is connected to the water replenishing pipe 4. The spray pipes 51 are arranged at intervals in the vertical direction above the gas pipe 3, and a plurality of nozzles 52 are provided at the lower end of the spray pipe 51. The plurality of nozzles 52 are arranged at intervals in sequence along the axial direction of the spray pipe 51.

[0049] Referring to Figure 2 and Figure 3 When the water replenishing pipe 4 and the plurality of spray pipes 51 are both located above the gas pipe 3 in the vertical direction, when the gas is discharged from the micropores on the gas pipe 3, normal temperature pure water is introduced into the water replenishing pipe 4. The normal temperature pure water flows into the plurality of spray pipes 51 and is sprayed out through the corresponding nozzles 52. At this time, the gas discharged from the micropores on the gas pipe 3 moves upward, and the normal temperature pure water discharged from the nozzles 52 moves downward. The gas and the normal temperature pure water are in countercurrent contact, and at this time, the gas and the normal temperature pure water are in full contact, thereby realizing the gas washing function.

[0050] Referring to Figure 2 and Figure 3 A washing tank 21 is provided on the upper side of the washing tray 2. One end of the gas pipe 3 and the water replenishing pipe 4 both extend into the washing tank 21, and a plurality of spray pipes 51 are all located in the washing tank 21.

[0051] Since the washing tank 21 has the function of storing water, through the action of the spray component 5, part of the normal temperature pure water can be stored in the washing tank 21, and then the normal temperature pure water submerges the gas pipe 3, which makes the gas discharged from the gas pipe 3 directly enter the normal temperature pure water, realizing the washing of the gas.

[0052] Since the micropores on the gas pipe 3 of the present application are micron-sized, when the gas is discharged from the gas pipe 3, gas microbubbles will be formed in the normal temperature pure water, which can increase the contact area between the gas and the normal temperature pure water, and thus improve the gas washing effect. Specifically, in this embodiment, the gas microbubbles discharged into the washing tray 2 through the gas pipe 3 only need to stay in the washing tank 21 for no less than 1 second to effectively realize aeration washing.

[0053] Referring to Figure 2 and Figure 3 The length direction of the washing tray 2 is arranged along the axial direction of the tank body 1. Then, a plurality of drain holes 22 are provided on both sides in the width direction of the washing tray 2. The plurality of drain holes 22 are arranged at intervals in sequence along the length direction of the washing tray 2, and the drain holes 22 are communicated with the washing tank 21.

[0054] The opening of the drain holes 22 enables the water in the washing tank 21 to flow into the interior of the tank body 1, realizing the recovery and storage of normal-temperature pure water. Since the normal-temperature pure water can supplement the consumed water for the electrolysis equipment and can also recover the waste liquid washed out from the gas.

[0055] Refer to Figure 2 and Figure 3 In the tank body 1, a jacket plate 6 is further provided. A jacket groove 61 is formed on the upper side of the jacket plate 6, and the jacket groove 61 penetrates the jacket plate 6 along the width direction of the washing plate 2. The washing plate 2 is arranged in the jacket groove 61, and the opposite side walls of the washing plate 2 along its own length direction are respectively fixedly connected to the corresponding inner side walls of the jacket groove 61. A plurality of drain holes 22 are all communicated with the jacket groove 61.

[0056] Refer to Figure 3 On both opposite sides of the jacket plate 6, overflow plates 7 are provided. The two overflow plates 7 are arranged at intervals along the width direction of the washing plate 2. The length direction of the overflow plate 7 is arranged along the width direction of the jacket groove 61, and both sides of the length direction of the overflow plate 7 are respectively connected to the corresponding inner side walls of the jacket groove 61. One side of the width direction of the overflow plate 7 is connected to the bottom of the jacket groove 61. Then, a water storage interlayer 62 is formed between the overflow plate 7, the two opposite inner side walls of the jacket groove 61 and the washing plate 2, and a plurality of drain holes 22 are all communicated with the corresponding water storage interlayer 62. The upper side surface of the overflow plate 7 is located above the drain holes 22 in the vertical direction.

[0057] Refer to Figure 3 The setting of the overflow plate 7 forms the water storage interlayer 62, so that normal-temperature pure water can be stored in the washing plate 2 and the jacket plate 6. When the liquid level height of the normal-temperature pure water is higher than the height of the overflow plate 7, the normal-temperature pure water in the water storage interlayer 62 is discharged into the tank body 1, which can realize the collection of normal-temperature pure water. Since there is normal-temperature pure water with a constant liquid level height in the washing plate 2, the gas discharged from the gas pipe 3 will always pass through the normal-temperature pure water with a constant height, which ensures the stability of the gas pressure and the washing effect. For the electrolysis equipment, the stability of the gas pressure is crucial.

[0058] Refer to Figure 3 On the side of the overflow plate 7 facing the washing plate 2, a plurality of comb grooves 71 are formed through holes. The length direction of the comb grooves 71 is arranged in the vertical direction, and the upper ends of the comb grooves 71 penetrate the overflow plate 7. A plurality of comb grooves 71 are arranged at equal intervals in sequence along the length direction of the overflow plate 7.

[0059] When the liquid level height in the water storage interlayer 62 is higher than the bottom of the comb grooves 71, the normal-temperature pure water in the water storage interlayer 62 will be discharged into the tank body 1 through a plurality of comb grooves 71. Due to the setting of a plurality of comb grooves 71, the overflow plate 7 has a comb-shaped structure, which can ensure that the normal-temperature pure water in the washing plate 2 can overflow into the tank body 1 quickly and evenly.

[0060] Refer toFigure 1 One end of the tank body 1 in the axial direction is provided with a waste liquid inlet 14, the other end is provided with a waste liquid replenishment inlet 15, and the lower side of the tank body 1 is provided with a waste liquid outlet 16.

[0061] Referring to Figure 1 Due to the opening of the waste liquid inlet 14, the gas discharged from the electrolysis equipment and the waste liquid settled in the waste liquid can be directly discharged into the tank body 1, which enables the small amount of gas contained in the waste liquid to overflow from the waste liquid and finally be discharged from the gas outlet 12.

[0062] Referring to Figure 1 Due to the opening of the waste liquid replenishment inlet 15, waste liquid can be replenished into the tank body 1. On the one hand, since the addition of normal temperature pure water will affect the concentration of the waste liquid, waste liquid can be added into the tank body 1 through the waste liquid replenishment inlet 15, so as to maintain the concentration of the waste liquid and enable the waste liquid to be reused; on the other hand, since the waste liquid needs to pass through many devices during the recycling process, the waste liquid is likely to decrease due to leakage. At this time, the waste liquid can be replenished through the waste liquid replenishment inlet 15.

[0063] Referring to Figure 1 The setting of the waste liquid outlet 16 is used to recover the waste liquid and normal temperature pure water. Then, after passing through the waste liquid heat exchange and filtration processes, the waste liquid can return to the electrolysis equipment again.

[0064] Referring to Figure 1 and Figure 2 A liquid level gauge is arranged in the tank body 1. In this embodiment, in order to optimize the effect of the gas scrubbing tank and improve the working efficiency of the gas scrubbing tank, the liquid level gauge controls the liquid level height of the waste liquid in the tank body 1 at 20% - 25% of the height of the tank body 1; the horizontal cross-sectional area of the scrubbing tray 2 accounts for 40% - 50% of the maximum horizontal cross-sectional area of the tank body 1, and the distance from the upper side of the scrubbing tray 2 to the inner top of the tank body 1 is not greater than 20% of the total height of the tank body 1.

[0065] The implementation principle of the embodiment of the present application is as follows: Since the electrolysis equipment discharges waste liquid and gas at the same time, the waste liquid is discharged into the tank body 1 through the waste liquid inlet 14, then the tank body 1 realizes the storage of the waste liquid, and a small amount of gas contained in the waste liquid will automatically float out from the waste liquid. The gas is discharged into the gas pipe 3 through the gas inlet 11, and the gas is discharged into the scrubbing tray 2 through the micropores on the gas pipe 3, and the gas continues to float upward out of the scrubbing tray 2; at the same time, the spraying assembly 5 sprays normal temperature pure water, and a part of normal temperature pure water is also stored in the scrubbing tray 2, then the gas will come into full contact with the normal temperature pure water to realize gas scrubbing. The normal temperature pure water after scrubbing flows through the drain holes 22 and the scrubbing grooves 21 and flows into the waste liquid in the tank body 1. During this process, the liquid level gauge real-time detects the liquid level height of the waste liquid in the tank body 1.

[0066] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
