Description

Technical Field

[0001] The utility model relates to the technical field of hydrochloric acid tail gas absorption, in particular to a hydrochloric acid tail gas absorption device. Background Art

[0002] Hydrochloric acid is a very important chemical agent. During the production process of hydrochloric acid, due to its certain volatility, the waste gas discharged during the production process will contain a certain amount of hydrochloric acid. If it is directly discharged into the atmosphere, it will cause damage to the factory facilities and equipment around the factory, and it is easy to have an adverse impact on the lives of residents, affect the health and safety of workers, and cause environmental pollution.

[0003] Existing hydrochloric acid tail gas absorption devices all achieve the effect of filtering and purifying the hydrochloric acid tail gas by adsorbing the hydrochloric acid tail gas on the activated carbon filter layer. However, such purified tail gas still contains some acidity, which is easily formed into acid rain when discharged into the atmosphere and contacts with the atmosphere, which is detrimental to the overall environment.

[0004] The existing patent (Announcement No.: CN215506240U) is a hydrochloric acid tail gas absorption device, which includes an installation box, a handle, a baffle, an exhaust pipe, a water box, a water inlet pipe and a water pipe. The water inside the water tank is sucked into the water pipe through a water pump, and then the water inside the water pipe is sprayed onto the activated carbon filter layer through a spray head. During the spraying process, the water contacts the hydrochloric acid tail gas, so as to reduce the acidity of the hydrochloric acid tail gas and neutralize the discharged tail gas. A purification chamber is provided, and the hydrochloric acid tail gas sucked by the fan is discharged into the purification chamber. Since the space inside the purification chamber is relatively small, the hydrochloric acid tail gas can fully contact the activated carbon filter layer and the sprayed water, and the hydrochloric acid tail gas can achieve the purification effect in the fastest time.

[0005] However, the above technical solution still has certain shortcomings. The exhaust gas is filtered by activated carbon and sprayed water mist. Through the water mist, the exhaust gas cannot be fully integrated with water, resulting in poor filtering effect, and the exhausted gas will still pollute the environment. Utility Model Content

It is connected to the other side of the filter box 3, and multiple groups of air outlet holes 270 are opened at the bottom of the diverter plate 260. The motor 210 is fixedly installed at the bottom of the mixing box 1. The output end of the motor 210 is fixedly connected to the first bevel gear 220, and the first bevel gear 220 is meshed with the second bevel gear 230. The second bevel gear 230 is fixedly sleeved on the outer wall of the rotating cylinder 240, and one end of the rotating cylinder 240 extends to the inside of the mixing box 1 and is connected to the stirring rod 250. The rotating cylinder 240 is movably installed in the mixing box 1 through a bearing. The air outlet pipe 280 extends to the inside of the rotating cylinder 240, and the air outlet pipe 280 and the rotating cylinder 240 are rotatably connected through a bearing. The mixing box 1 is filled with water, and the water level is higher than the diverter plate 260.

[0025] The exhaust gas enters the filter box 3 through the air inlet pipe 4, first contacts the activated carbon plate 6 for a filtration, and then enters the mixing box 1 through the air outlet pipe 280. The exhaust gas is dispersed and injected into the air outlet 270 through the diverter plate 260. The exhaust gas then contacts the water and rotates through the motor 210, driving the first bevel gear 220 to rotate, and at the same time driving the second bevel gear 230 that is engaged to rotate, driving the rotating cylinder 240 and the stirring rod 250 to rotate, and then the bubbles ejected by the bubbles pass through the stirring rod 250 and are broken up into finer bubbles, so that the bubbles are more fully contacted with the water, thereby increasing the filtering effect.

[0026] Please refer to Figure 1 , Figure 4 and Figure 5The disassembly and assembly components include a turning handle 710, which extends to the inside of the mounting plate 5 through a turning rod and is fixedly connected to the turntable 720. Pull rods 730 are provided on both sides of the turntable 720, and a connecting block 740 is provided on one side of the pull rod 730. The connecting block 740 is connected to the limit block 750 through the connecting rod. The mounting plate 5 and the filter box 3 are connected through a sealing ring 8. One end of the pull rod 730 is rotatably connected to the turntable 720 through a rotating shaft, and the other end of the pull rod 730 is rotatably connected to the connecting block 740 through a rotating shaft. A spring is provided between one end of the limit block 750 and the inner wall of the mounting plate 5, and the spring is sleeved on the outer wall of the connecting rod. The other end of the limit block 750 extends to the inside of the filter box 3, and a limit groove matching the limit block 750 is opened inside the filter box 3.

[0027] Rotating the handle 710 drives the rotating rod to rotate, and at the same time drives the rotating disk 720 to rotate. The rotation of the rotating disk 720 drives the pull rod 730 to rotate inward, and then drives the connecting block 740 to move inward. The connecting rod drives the limit block 750 to disengage from the limit groove inside the filter box 3, thereby pulling the handle 710 upward, driving the mounting plate 5 and the activated carbon plate 6 to move upward, and replacing the activated carbon plate 6 to prevent the activated carbon plate 6 from being used for a long time and the adsorption capacity from deteriorating, resulting in an unsatisfactory absorption effect on the exhaust gas.

[0028] When in use, the exhaust gas enters the filter box 3 through the air inlet pipe 4, first contacts with the activated carbon plate 6 for a filtration, and then enters the mixing box 1 through the air outlet pipe 280, and the exhaust gas is dispersed and injected into the air outlet 270 through the diverter plate 260, and then the exhaust gas contacts with water, and the motor 210 rotates, driving the first bevel gear 220 to rotate, and at the same time driving the second bevel gear 230 that is engaged to rotate, driving the rotating cylinder 240 and the stirring rod 250 to rotate, and then the bubbles ejected by the stirring rod 250 are broken up into finer bubbles, so that they are mixed with the water. The contact with water is more complete, which increases the filtering effect. The rotating handle 710 drives the rotating rod to rotate, and at the same time drives the rotating disk 720 to rotate. The rotation of the rotating disk 720 drives the pull rod 730 to rotate inward, and then drives the connecting block 740 to move inward. The connecting rod drives the limit block 750 to disengage from the limit groove inside the filter box 3, thereby pulling the rotating handle 710 upward, driving the mounting plate 5 and the activated carbon plate 6 to move upward, and replacing the activated carbon plate 6 to prevent the activated carbon plate 6 from being used for a long time and the adsorption capacity from deteriorating, resulting in unsatisfactory absorption effect on the exhaust gas.
