[0002] The function of the gas stripping tower of electronic grade sulfuric acid is to remove the reducing substances dissolved in the sulfuric acid by passing air into the acid solution. The key component is the insertion tube for passing compressed air into the gas stripping tower. The structure of the existing insertion tube is a straight tube, but a hole with a diameter of 15 mm is opened on the tube wall. When the gas is passed into the pipeline of the insertion tube, it is ejected from the hole in the tube wall and enters the acid solution. However, the gas ejected from the insertion tube generally exists around the insertion tube, resulting in a small contact area between the gas and the acid solution, so the removal effect of the reducing substances is not good. In order to remove the reducing substances, a large amount of gas needs to be passed, resulting in a large gas consumption. Utility Model Content

[0019] The following will clearly and completely describe the technical solutions in the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present utility model.
[0020] Reference Figure 1-Figure 5 As shown, a gas stripping tower device for acid solution production includes a gas stripping tower body 1, a vent pipe 2, and a rotating mechanism 3. The top of the gas stripping tower body 1 is provided with a through hole 11. The vent pipe 2 is arranged in the gas stripping tower body 1. The vent pipe 2 is in a T-shaped structure. The vent pipe 2 includes a transverse pipe 21 and a vertical pipe 22 connected to the transverse pipe 21. The transverse pipe 21 and the vertical pipe 22 are integrally formed. The wall of the transverse pipe 21 is provided with a plurality of fine holes 211. The fine holes 211 are used to spray the gas in the vent pipe 2 to enter the acid solution to react with the reducing substances in the acid solution. The vertical pipe 22 is arranged in the through hole 11 and extends out of the gas stripping tower body 1. The rotating mechanism 3 is arranged at the top of the gas stripping tower body 1. The rotating mechanism 3 is connected to the vertical pipe 22 to drive the vent pipe 2 to rotate, so that the gas ejected from the fine hole 211 can contact with more acid solution, thereby increasing its contact area with the acid solution, improving the removal efficiency of the reducing substances in the sulfuric acid, and reducing the gas consumption. At the same time, the rotating vent pipe 2 also has a stirring effect, thereby increasing the reaction rate of the gas and the reducing substances, and further improving the removal efficiency of the reducing substances in the sulfuric acid.
[0021] The rotating mechanism 3 includes a motor frame 31, a driving motor 32, and a transmission assembly 33. The motor frame 31 is arranged on the top of the gas stripping tower body 1, the motor frame 31 is located next to the through hole 11, the driving motor 32 is arranged on the motor frame 31, and the transmission assembly 33 is arranged between the driving motor 32 and the vertical pipe 22 to drive the vertical pipe 22 to rotate around its central axis. The driving motor 32 is a servo motor.
[0022] The transmission assembly 33 includes a driving gear 331 and a driven gear 332 . The driving gear 331 is disposed on the driving motor 32 , and the driven gear 332 is disposed on the vertical pipe 22 . The driving gear 331 is meshedly connected with the driven gear 332 .
[0023] A sealing mechanism 4 is provided between the through hole 11 and the vertical pipe 22, and the sealing mechanism 4 is used to seal the gap between the vertical pipe 22 and the through hole 11. The sealing mechanism 4 includes a sealing groove 41 and a fluororubber sealing ring 42. The sealing groove 41 is provided on the side wall of the through hole 11, the fluororubber sealing ring 42 is provided in the sealing groove 41, and the fluororubber sealing ring 42 is sleeved on the vertical pipe 22. Specifically, the fluororubber sealing ring 42 has high corrosion resistance, including acid and alkali, and can be used for a long time in various strong acid (such as sulfuric acid, nitric acid, hydrochloric acid, etc.) and strong alkali (such as sodium hydroxide, potassium hydroxide, etc.) environments without being damaged.
[0024] A connection joint 5 is provided at the top of the vertical pipe 22, and the connection joint 5 is used to connect with the gas storage tank. The connection joint 5 is a HS-G type rotary joint.
[0025] The diameter of the pores 211 is 2-3 mm. When the gas enters the pipe of the vent pipe 2, the gas pressure in the pipe will increase due to the small diameter of the pores 211. When passing through the pores 211, the gas flow rate will increase, and the gas will be sprayed into the acid solution at a very fast speed, which is more effective in removing the reducing substances dissolved in the acid solution. Moreover, because the diameter of the pores 211 is small, the number of pores 211 that can be opened in the same pipe is increased, so that the contact area between the gas and the acid solution is also increased, which is more conducive to removing the reducing substances.
[0026] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
