Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a sulfur scrubber for treating waste gas. Background Technology

[0002] The semiconductor manufacturing process generates sulfide-containing waste gases, which can adversely affect equipment, products, personnel health, and the environment. Therefore, scrubbers are needed to desulfurize these gases. For example, Chinese utility model patent application number CN202122130914.8 provides a highly efficient sulfur scrubber with a neutralization effect. In operation, a pump draws the scrubbing liquid from the storage chamber into the filter box, which then flows into the spray pipe. Finally, the liquid is sprayed from the spray head into the neutralization chamber, where it reacts with the sulfides in the waste gas, thus achieving desulfurization.

[0003] However, this device has a drawback: all the spray heads are positioned at the same height at the top of the neutralization chamber. When exhaust gas enters the neutralization chamber, only the exhaust gas near the top can come into contact with and react with the newly sprayed washing liquid, while the exhaust gas near the bottom can only come into contact with the reacted washing liquid. This results in a better desulfurization effect at the top of the neutralization chamber than at the bottom, thus reducing the overall desulfurization speed. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0020] Example 1 Please see Figure 1-12This utility model provides a technical solution: a sulfur scrubber for treating waste gas, comprising a scrubbing tank 1, a spray assembly 2, and an air inlet assembly 3. The spray assembly 2 includes a first liquid storage box 21, a second liquid storage box 22, a plurality of first nozzles 23, a plurality of second nozzles 24, a first drain assembly 25, and a second drain assembly 26. The first liquid storage box 21 and the second liquid storage box 22 are filled with scrubbing liquid. The plurality of first nozzles 23 and the plurality of second nozzles 24 are arranged at equal intervals from top to bottom and are radially and uniformly distributed. The first drain assembly 25 is used to pump the scrubbing liquid from the first liquid storage box 21 into the first nozzles 23, and the second drain assembly 26 is used to pump the scrubbing liquid from the second liquid storage box 22 into the second nozzles 24. The air inlet assembly 3 includes an annular air inlet pipe 31, a first branch pipe 32, and a second branch pipe 33. In use, the exhaust gas first enters the annular inlet pipe 31 through the first branch pipe 32, then enters the second branch pipe 33 through the annular inlet pipe 31, and finally enters the scrubbing tank 1 through the second branch pipe 33, reaching below the spray assembly 2 inside the scrubbing tank 1. The exhaust gas then moves upward through the gap between the first liquid storage box 21 and the second liquid storage box 22. Next, the spray assembly 2 operates, with several first nozzles 23 and several second nozzles 24 spraying scrubbing liquid outward. During the upward movement of the exhaust gas, it continuously contacts and reacts with the newly sprayed scrubbing liquid, maintaining a balanced desulfurization effect at different positions in the vertical direction, thus accelerating the overall desulfurization speed.

[0021] Please see Figure 1-6 The first drainage assembly 25 includes a first annular partition 251, a first electrically controlled valve 252, a circular pressure plate 253, and a first actuator 254. The first annular partition 251 divides the interior of the first liquid storage box 21 into a first liquid storage chamber 211 and a second liquid storage chamber 212. The first actuator 254 includes a first electrically operated telescopic rod 2541 and a first drive rod 2542, with the output end of the first actuator 254 connected to the circular pressure plate 253. When the spray assembly 2 is not in operation, the first liquid storage chamber 211 is filled with washing liquid, the circular pressure plate 253 is located at the top of the first liquid storage chamber 211, and the first electrically controlled valve 252 is in the closed state. When the spray assembly 2 is in operation, the first electrically controlled valve 252 opens, the first electrically operated telescopic rod 2541 extends, driving the first drive rod 2542 to move downward, and the first drive rod 2542 drives the circular pressure plate 253 to move downward. The circular pressure plate 253 applies pressure to the washing liquid in the first liquid storage chamber 211. The washing liquid in the first liquid storage chamber 211 enters the second liquid storage chamber 212 through the first electrically controlled valve 252. Since the volume of the second liquid storage chamber 212 is very small, the washing liquid will fill the second liquid storage chamber 212 in a very short time. Then, the washing liquid in the second liquid storage chamber 212 will enter several first nozzles 23 and be sprayed outwards.

[0022] Please see Figure 1-9The second drainage assembly 26 includes a second annular partition 261, a second electrically controlled valve 262, an annular pressure plate 263, and a second actuator 264. The second annular partition 261 divides the interior of the second liquid storage box 22 into a third liquid storage chamber 221 and a fourth liquid storage chamber 222. The second actuator 264 includes a second electrically operated telescopic rod 2641 and a second drive rod 2642, with the output end of the second actuator 264 connected to the annular pressure plate 263. When the spray assembly 2 is not in operation, the third liquid storage chamber 221 is filled with washing liquid, the annular pressure plate 263 is located at the top of the third liquid storage chamber 221, and the second electrically controlled valve 262 is in the closed state. When the spray assembly 2 is in operation, the second electrically controlled valve 262 opens, the second electrically operated telescopic rod 2641 extends, driving the second drive rod 2642 to move downward, and the second drive rod 2642 drives the annular pressure plate 263 to move downward. The annular pressure plate 263 applies pressure to the washing liquid in the third liquid storage chamber 221. The washing liquid in the third liquid storage chamber 221 enters the fourth liquid storage chamber 222 through the second electrically controlled valve 262. Since the volume of the fourth liquid storage chamber 222 is very small, the washing liquid will fill the fourth liquid storage chamber 222 in a very short time. Next, the washing liquid in the fourth liquid storage chamber 222 will enter several second nozzles 24 and be sprayed outwards.

[0023] Please see Figure 1-10 This invention also includes a liquid transfer assembly 4, which comprises a collection box 41, a third branch pipe 42, a third electrically controlled valve 43, a fourth branch pipe 44, a fourth electrically controlled valve 45, a fifth branch pipe 46, and a fifth electrically controlled valve 47. In use, the washing liquid sprayed through the first nozzle 23 and the second nozzle 24 reacts with the exhaust gas and falls into the collection box 41 for collection. At this time, the third electrically controlled valve 43 is closed. After all the exhaust gas has been desulfurized, the third electrically controlled valve 43 opens, and the washing liquid in the collection box 41 enters the third branch pipe 42 through the third electrically controlled valve 43, and is then discharged through the third branch pipe 42. When the spray assembly 2 is working, the fourth electrically controlled valve 45 and the fifth electrically controlled valve 47 are in the closed state. After all the exhaust gas has been desulfurized, the tank door 11 on the side wall of the washing tank 1 is opened, and a conveying pipe is connected to the fourth branch pipe 44 and the fifth branch pipe 46. Then, the fourth electrically controlled valve 45 and the fifth electrically controlled valve 47 are opened, and the first electrically controlled valve 252 and the second electrically controlled valve 262 are closed. At this time, the first actuator 254 drives the circular pressure plate 253 to move upward, and the second actuator 264 drives the annular pressure plate 263 to move upward, so that the washing liquid can be replenished into the first liquid storage chamber 211 and the third liquid storage chamber 221 through the conveying pipe.

[0024] Example 2 Based on Example 1, please refer to Figure 1-11This utility model also includes a gas guiding component 5, which includes a motor 51, a drive frame 52, an annular assembly plate 53, and several guide plates 54, all of which are inclined. There are several second branch pipes 33, which are radially and evenly distributed, and are also inclined. These second branch pipes 33 can simultaneously discharge waste gas into the washing tank 1. Then, the gas guiding component 5 operates, with the motor 51 driving the drive frame 52 to rotate. The drive frame 52 rotates together with the several guide plates 54 via the annular assembly plate 53. The guide plates 54 cause the waste gas in the washing tank 1 to rise in a spiral shape, allowing the waste gas to come into contact with the washing liquid sprayed from more locations when passing through the gap between the first liquid storage box 21 and the second liquid storage box 22, thus enhancing the desulfurization effect.

[0025] Example 3 Based on Example 2, please refer to Figure 1-12 This invention also includes a filter assembly 6, which comprises several activated carbon filter cartridges 61, a first annular gas-gathering hood 62, a second annular gas-gathering hood 63, and an exhaust hood 64. After the waste gas reacts with the washing liquid and passes through the gap between the first liquid storage box 21 and the second liquid storage box 22, it enters the first annular gas-gathering hood 62. Subsequently, the waste gas enters the bottom of the activated carbon filter cartridges 61, where the activated carbon filter cartridges 61 adsorb the toxic and harmful gases in the waste gas. Next, the waste gas enters the second annular gas-gathering hood 63 from the top of the activated carbon filter cartridges 61, and then enters the exhaust hood 64 through the second annular gas-gathering hood 63, finally being discharged through the exhaust pipe 641 at the top of the exhaust hood 64. In this invention, the first liquid storage box 21 and the first actuator 254 are both fixedly connected to the second annular gas-gathering hood 63, and the second liquid storage box 22 and the second actuator 264 are both fixedly connected to the washing tank 1. The bottom and top of the activated carbon filter cartridges 61 are respectively installed in the first assembly hole 621 and the second assembly hole 631. After the activated carbon filter cartridge 61 has been used for a period of time, first remove the exhaust hood 64 and the second annular gas concentrator hood 63 from the top of the washing tank 1, and then remove the activated carbon filter cartridge 61 from the first annular gas concentrator hood 62 to replace it with a new activated carbon filter cartridge 61.
