Description

Technical Field

[0001] This utility model relates to the field of vacuum pump acid removal technology, specifically a condensation acid removal tank. Background Technology

[0002] In the manufacturing process of lithium-ion batteries, vacuum pumps are often used. However, the manufacturing process also generates some acidic gases, including hydrogen fluoride, organic acids, and carbonic acid. If these acidic gases enter the vacuum pump while it is operating, they can corrode the internal components and damage the pump. Therefore, it is necessary to perform preliminary deacidification on the gases entering the vacuum pump.

[0003] Therefore, the technical problem to be solved in this case is: how to reduce the concentration of acid in the gas entering the vacuum pump. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a condensation deacidification tank. Acidic gas enters the tank body through the inlet and is condensed sequentially through condenser tubes. A grid plate traps the gas into droplets, which are then discharged through the drain port. As the acidic gas condenses through the condenser tubes, it transforms from a gaseous state to a liquid state. Upon impacting the grid plate, the small acidic gas molecules collide with each other to form droplets, which then drip from the grid plate to the drain port of the tank body. Some uncondensed gas is discharged to the vacuum pump through the exhaust port, thus achieving preliminary deacidification. By reducing the acid concentration in the gas, excessively high acid concentrations can prevent corrosion of the vacuum pump body, thereby better protecting the vacuum pump body.

[0005] The technical solution of this utility model is:

[0006] A condensation deacidification tank includes a tank body and a condenser pipe. The tank body is provided with multiple layers of mesh plates, which divide the tank body into a condensation zone and an exhaust zone. The tank body is provided with an air inlet and an exhaust outlet. The air inlet is connected to the condensation zone, and the exhaust outlet is connected to the exhaust zone. The condenser pipe is located within the condensation zone. The bottom of the tank body is provided with a drain outlet. Gas enters the tank body through the air inlet, passes through the condensation zone and the multiple layers of mesh plates in sequence, and is discharged from the exhaust outlet. The mesh plates are used to collect the condensate formed by the gas passing through the condenser pipe.

[0007] Preferably, the tank is provided with a fixed platform, which protrudes from the inner peripheral wall of the tank, and multiple layers of the grid plates can be stacked on the fixed platform.

[0008] Preferably, the condensation deacidification tank further includes a support frame, with multiple layers of the mesh plate connected within the support frame, and the support frame resting on the fixed platform.

[0009] Preferably, the top of the support frame is provided with barbs.

[0010] Preferably, the top of the tank is provided with a removable sealing cap.

[0011] Preferably, the mesh plate is made of stainless steel.

[0013] Preferably, the bottom of the tank body is spherical, and the drain outlet is located in the middle of the bottom of the tank body.

[0014] Preferably, the condenser tube is made of stainless steel.

[0015] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0016] This invention introduces acidic gas into the tank through the inlet, where it is condensed sequentially by condenser tubes. A grid plate traps the gaseous gas as droplets, which are then discharged through the drain outlet. As the acidic gas condenses through the condenser tubes, it transforms from a gaseous to a liquid state. Upon impact with the grid plate, the small acidic gas molecules collide to form droplets, which then drip from the grid plate to the drain outlet of the tank. Some uncondensed gas is discharged to the vacuum pump through the exhaust port, thus achieving preliminary acid removal. By reducing the acid concentration in the gas, excessively high acid concentrations are avoided, preventing corrosion of the vacuum pump body and better protecting it. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1 A condensation deacidification tank includes a tank body 1 and a condenser pipe 2. The tank body 1 is provided with multiple layers of mesh plates 3, which divide the tank body 1 into a condensation area and an exhaust area. The tank body 1 is provided with an air inlet 11 and an exhaust outlet 12. The air inlet 11 is connected to the condensation area, and the exhaust outlet 12 is connected to the exhaust area. The condenser pipe 2 is located in the condensation area. The bottom of the tank body 1 is provided with a drain outlet 13. Gas enters the tank body 1 through the air inlet 11 and passes through the condensation area and the multiple layers of mesh plates 3 in sequence, and is discharged from the exhaust outlet 12. The mesh plates 3 are used to capture the condensate formed by the gas passing through the condenser pipe 2.

[0022] It should be noted that this embodiment uses the removal of acid from vacuum pumps in the lithium electronics industry as an example.

[0023] In practical applications, the production of lithium batteries in the lithium electronics industry generates acidic gases such as hydrogen fluoride, organic acids, and carbonic acid. When a vacuum pump operates for an extended period, these acidic gases can corrode the pump body, damaging the pump. Therefore, this deacidification tank can perform preliminary deacidification of these gases, reducing the acid concentration of the gas entering the vacuum pump. The acidic gases enter the condensation deacidification tank through inlet 11 and are condensed through condenser tubes 2 in the condensation area. The acidic gases transform from gaseous molecules to liquid molecules, and the liquid molecules move upwards, passing through multiple layers of mesh during this movement. In plate 3, liquid molecules collide with each other within the multi-layered mesh plate 3, gradually forming large droplets that drip from the mesh plate 3 to the drain port 13 at the bottom of the tank 1 and are discharged outwards. Meanwhile, the incompletely condensed gas enters the vacuum pump body from the exhaust port 12. By passing the acidic gas sequentially through the condensation zone, the multi-layered mesh plate 3, and the exhaust zone, the acid concentration in the gas is reduced, thereby preventing the excessively high acid concentration in the gas from corroding the vacuum pump body. This helps protect the vacuum pump body and improves the service life of the vacuum pump. It should be noted that a single mesh plate 3 is formed by stacking and welding multiple filter screens.

[0024] Preferably, the tank body 1 is provided with a fixed platform 14, which protrudes from the inner peripheral wall of the tank body 1, and multiple layers of the grid plates 3 can be stacked on the fixed platform 14.

[0025] Through the above design, the position of the grid plate 3 inside the tank 1 can be positioned by the fixed platform 14, preventing the grid plate 3 from being too low and causing gas to enter the grid plate 3 before it is completely condensed. This would reduce the possibility of forming droplets and thus reduce the acid removal efficiency. On the other hand, the operator only needs to lower the grid plate 3 from the top of the tank 1 into the tank 1 to place the grid plate 3 at the fixed platform 14, which makes it convenient for the operator to install the grid plate 3 inside the tank 1.

[0026] Preferably, the condensation deacidification tank further includes a support frame 4, with multiple layers of the mesh plate 3 connected inside the support frame 4, and the support frame 4 resting on the fixed platform 14.

[0027] In the above design, the grid plate 3 is connected to the support frame 4 by a snap-fit ​​method. Because acidic gas has a certain corrosive effect on the grid plate 3, when the grid plate 3 is damaged due to corrosion and needs to be replaced, multiple grid plates 3 can be replaced by replacing the support frame 4. This avoids the pump body of the vacuum pump being corroded due to the high concentration of acid in the gas, which would cause damage to the pump body. On the other hand, the support frame 4 can be placed directly on the fixed platform 14, which allows the staff to take out multiple layers of grid plates 3 at once, making it convenient for the staff to install or remove the grid plates 3. Preferably, the grid plate 3 can also be connected to the support frame 4 by bolts or welding.

[0028] Preferably, the top of the support frame 4 is provided with a barb.

[0029] With the above design, the staff can use the external device to pass through the barb and install the support frame 4 inside the tank 1 and attach it to the fixed platform 14. When disassembly is required, the support frame 4 can be hooked away from the tank 1 by passing through the barb through the external device, which facilitates the operation of the staff. It should be noted that the barb is not shown in the figure.

[0030] Preferably, the top of the tank body 1 is provided with a removable sealing cap 15.

[0031] In the above design, the sealing cover 15 can ensure the airtightness of the tank 1, and opening the sealing cover 15 can facilitate the installation or disassembly of the support frame 4 by the staff. Specifically, in this embodiment, the sealing cover 15 is detachably connected to the top of the tank 1 through the sealing flange. On the other hand, a vacuum gauge is provided on the side of the tank 1 away from the exhaust port 12, and the internal air pressure change can be observed through the vacuum gauge.

[0032] Preferably, the mesh plate 3 is made of stainless steel.

[0033] In this embodiment, since the mesh plate 3 comes into contact with acidic liquid molecules and the liquid molecules form droplets on the mesh plate 3, the environment in which the mesh plate 3 is located is a high humidity and acidic environment. Therefore, the stainless steel mesh plate 3 can improve the service life of the mesh plate 3.

[0034] Preferably, the water inlet of the condenser pipe 2 passes through the tank body 1 and is connected to an external condensate liquid source, and the water outlet passes through the tank body 1 and is connected to an external circulation device. The condenser pipe 2 is arranged in a spiral.

[0035] With the above design, the external condensate source will enter the condenser tube 2 through the water inlet and flow along the pipe of the condenser tube 2, and flow to the water outlet to flow to the external circulation device, thereby forming a circulating cooling water. The spiral arrangement of the condenser tube 2 can improve the condensation effect of the condensation area, which is beneficial to reducing the acid concentration in the gas. In this embodiment, the condensate source can be condensate or condensate water.

[0036] Preferably, the bottom of the tank 1 is spherical, and the drain port 13 is located in the middle of the bottom of the tank 1.

[0037] In the above design, the droplets dripping from the grid plate 3 will fall to the bottom of the tank 1. The droplets can be guided to the lowest point of the spherical bottom of the tank 1, which is the location of the drain port 13. The droplets are discharged outward from the drain port 13. As a preferred solution of this embodiment, the tank 1 is equipped with a level gauge. The level gauge can be used to observe whether the droplets formed by the acid gas can be discharged outward smoothly from the drain port 13.

[0038] Preferably, the condenser tube 2 is made of stainless steel.

[0039] With the above design, since the condenser tube 2 will preferentially come into contact with acidic gas, at which time the acid concentration in the gas is the highest, the stainless steel material can improve the corrosion resistance of the condenser tube 2, thereby increasing the service life of the condenser tube 2.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
