Description

Technical Field

[0001] This utility model relates to the field of waste gas scrubbing tower technology, and more specifically, to a waste gas scrubbing tower device with the function of recovering organic solvents. Background Technology

[0002] A waste gas scrubbing tower is an environmental protection device used to treat industrial waste gas. It primarily removes harmful components from the waste gas by ensuring sufficient contact between the waste gas and the scrubbing liquid. Its working principle is as follows: waste gas enters the scrubbing tower from the bottom or side, while the scrubbing liquid is sprayed down from the top. As the waste gas rises, it flows counter-currently to the scrubbing liquid and comes into contact with it. During this process, particulate matter, acidic gases (such as sulfur dioxide and hydrogen chloride), alkaline gases, and organic pollutants in the waste gas dissolve in the scrubbing liquid or react chemically with it, thereby purifying the waste gas.

[0003] However, after the existing waste gas scrubbing tower device washes and purifies the waste gas, harmful substances such as particulate matter, alkaline gases, and organic pollutants in the waste gas will dissolve in the scrubbing liquid. When the existing waste gas scrubbing device recovers these organic pollutants, it mostly uses filtration to intercept them and then remove these organic solutions. However, filtration is costly and often requires the purchase of expensive filtration equipment, which undoubtedly brings great costs to actual use.

[0004] Secondly, the use of filters for separation and filtration often requires the replacement and cleaning of the filter screen. Long-term use results in high wear and tear costs, and subsequent maintenance is also inconvenient, bringing great labor intensity to the staff.

[0005] In view of this, we propose a waste gas scrubbing tower device with the function of recovering organic solvents. Utility Model Content

[0006] Technical problems to be solved

[0007] The purpose of this invention is to provide a waste gas scrubbing tower device with the function of recovering organic solvents, so as to solve the problems mentioned in the background art.

[0008] Technical solution

[0009] A waste gas scrubbing tower device with organic solvent recovery function includes a water storage tank. An observation window is provided on the front outer wall of the water storage tank. A sealing groove and a locking interface are provided on the side wall of the water storage tank. A limit rod is also threadedly connected to the side wall of the water storage tank. A discharge valve and a circulation pump are provided on the other outer wall of the water storage tank. A locking plate is locked inside the locking interface. A fixing plate is fixedly connected to one side of the locking plate's outer wall. A sieve plate is provided on the other side of the locking plate's outer wall. A tower body is provided on the top of the water storage tank. A buffer assembly is provided on the inner wall of the tower body, and the buffer assembly includes a support rod.

[0010] Preferably, the output end of the circulating pump is connected to a water supply pipe, the end of the water supply pipe extends to the tower body and is connected to a connecting water pipe, and the end of the connecting water pipe is connected to a spray head.

[0011] Preferably, the outer wall of the fixing plate is provided with a sealing strip, and the sealing strip matches the sealing groove.

[0012] Preferably, the top of the sieve plate has multiple through holes, and the top of the sieve plate is also provided with a trapezoidal frame, the trapezoidal frame has a cavity inside, and a stainless steel filter plate is also snapped onto the top of the trapezoidal frame.

[0013] Preferably, the inner wall of the cavity has a through-hole, the suction end of the circulating pump extends through the through-hole into the cavity, and the sieve plate is located in the middle of the inner wall of the water storage tank.

[0014] Preferably, an exhaust pipe is provided at the top of the tower body, and an exhaust gas inlet is provided on the outer wall of the tower body.

[0015] Preferably, a spring buffer is connected between the plurality of support rods, and a buffer water guide is fixedly connected to the bottom of the spring buffer. Beneficial effects

[0016] Compared with existing technologies, the advantages of this invention are as follows: During use, waste gas can be introduced through the waste gas inlet, and then the circulation pump is started to transport water from the water storage tank to the spray head for spraying. At this time, the washing water can fully contact the waste gas, thereby purifying the waste gas. After washing, the washing water will undergo initial buffering through the buffer component, and finally fall on the top of the screen plate for further buffering, reducing the impact of the spray water on the organic solvents deposited at the bottom of the water storage tank. After the water flows to the top of the screen plate, since the specific gravity of the organic solution is greater than that of the washing water, these organic solutions will accumulate at the bottom of the inner cavity of the water storage tank due to gravity, which facilitates the later discharge using the discharge valve, thereby achieving the purpose of organic solvent recovery. During the initial buffering process using the buffer component, the spray water flowing out from one side of the buffer guide frame can also rinse the surface of the stainless steel filter plate to a certain extent, thereby further reducing the frequency of manual cleaning of the stainless steel filter plate. The implementation of this device can not only extend the adsorption time of the activated carbon at the end of the VOCs treatment device, but also increase the economic benefits of organic solvent recovery and reduce the economic burden caused by using expensive filtration devices for separation.

[0017] Furthermore, during use, a single stainless steel filter plate can intercept a large amount of impurities, reducing the risk of blockage in the circulating pump and spray head during the circulating washing process. Additionally, the spray water can be used for rinsing, further enhancing its practicality and economy. Attached Figure Description

An observation window 110 is provided on the outer wall of the front of the water storage tank 100. A sealing groove 120 and a card interface 130 are provided on the side wall of the water storage tank 100. A limit rod 140 is also threadedly rotatably connected to the side wall of the water storage tank 100.

[0028] In some embodiments, the multiple limit rods 140 can limit the fixed plate 200 and also allow the screen plate 230 to be easily removed for maintenance.

[0029] A discharge valve 150 and a circulation pump 160 are provided on the outer wall of the other side of the water storage tank 100. A snap-fit ​​plate 220 is snapped into the snap-fit ​​interface 130. A fixing plate 200 is fixedly connected to one side of the outer wall of the snap-fit ​​plate 220. A screen plate 230 is provided on the outer wall of the other side of the snap-fit ​​plate 220. A tower body 300 is provided on the top of the water storage tank 100. A buffer assembly is provided on the inner wall of the tower body 300. The buffer assembly includes a support rod 320.

[0030] Specifically, the output end of the circulating pump 160 is connected to a water supply pipe 161, and the end of the water supply pipe 161 extends to the tower body 300 and is connected to a connecting water pipe 162. The end of the connecting water pipe 162 is connected to a spray head 163, which facilitates water spraying and washing of the exhaust gas.

[0031] Furthermore, a sealing strip 210 is provided on the outer wall of the fixing plate 200. The sealing strip 210 matches the sealing groove 120 to improve its sealing performance after installation.

[0032] Furthermore, the top of the sieve plate 230 has multiple through holes, and the top of the sieve plate 230 is also provided with a trapezoidal frame 240. The trapezoidal frame 240 has a cavity 241 inside, and a stainless steel filter plate 250 is also snapped onto the top of the trapezoidal frame 240.

[0033] Furthermore, a through-hole 242 is provided on the inner wall of the cavity 241, through which the suction end of the circulating pump 160 extends into the cavity 241, and the sieve plate 230 is located in the middle of the inner wall of the water storage tank 100.

[0034] In some embodiments, the circulation pump 160 is installed at half the height of the side of the water storage tank 100 above the sieve plate 230 to reduce the possibility that the circulation pump inlet will remove the lower deposited solvent.

[0035] It is worth noting that an exhaust pipe 450 is installed at the top of the tower body 300, and an exhaust gas inlet 310 is installed on the outer wall of the tower body 300 to facilitate the entry and exit of exhaust gas.

[0036] It is worth noting that a spring damper 330 is connected between multiple support rods 320. A buffer water guide frame 340 is fixedly connected to the bottom of the spring damper 330 to facilitate the initial buffering of the spray water and reduce the impact force of the water flow. The spring damper 330 is existing technology and common models on the market can be selected.

[0037] In some embodiments, the device can be powered by an external conventional power source.

[0038] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0039] Working Principle: During use, exhaust gas enters through the exhaust gas inlet 310. Then, the circulation pump 160 is activated to transport water from the water storage tank 100 to the spray head 163 for spraying. The washing water then comes into full contact with the exhaust gas, purifying it. After washing, the water is initially buffered by a buffer assembly and then falls onto the top of the screen plate 230 for further buffering, reducing the impact of the spray water on the organic solvents deposited at the bottom of the water storage tank 100. Because the organic solvents are denser than the washing water, they accumulate at the bottom of the water storage tank 100 due to gravity, facilitating later discharge via the discharge valve 150. To achieve the goal of organic solvent recovery, during the initial buffering process using the buffer assembly, the spray water flowing out from one side of the buffer water guide 340 can also rinse the surface of the stainless steel filter plate 250 to a certain extent, thereby reducing the frequency of manual cleaning of the stainless steel filter plate. The implementation of this device can not only extend the adsorption time of the activated carbon at the end of the VOCs treatment device, but also increase the economic benefits of organic solvent recovery, reduce the economic burden caused by using expensive filtration devices for separation, and during use, only one stainless steel filter plate can intercept a large number of impurities, reducing the risk of blockage of the circulating pump and spray head during the circulating washing process. Secondly, it can also be rinsed by the spray water, which can better improve its practicality and economy.
