Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide stripping technology, specifically a demineralized water carbon dioxide removal device. Background Technology

[0002] The basic principle of the stripping method is to introduce air into the wastewater, thereby changing the gas-liquid balance established by the toxic and harmful gases dissolved in the water. This causes the volatile substances to change from the liquid phase to the gas phase, and then they are collected or discharged into the atmosphere after being treated to meet standards. The stripping process is a mass transfer process; its driving force is the concentration difference between the volatile substances in the wastewater and the concentration of the same substances in the atmosphere.

[0003] For example, an existing Chinese patent (publication number: CN207684930U) discloses a high-efficiency carbon dioxide stripping equipment for demineralized water. It uses a blower to blow air into the tank to remove free carbon dioxide from the water by degassing. Water is introduced from the top of the tank, sprayed by a spray device, and then flows through a packing layer with a large surface area. Air enters the tank from the air inlet at the bottom of the tank, passes upward through the packing layer, and the free carbon dioxide in the water is quickly released into the air and discharged with the air at the exhaust port at the top of the tank. The degassed water is discharged into a water tank for later use through the purified water outlet on the tank. This method effectively improves the removal efficiency of carbon dioxide stripping from demineralized water, with significant results and reduced equipment maintenance costs.

[0004] However, the above-mentioned demineralized water high-efficiency carbon dioxide stripping equipment still has some drawbacks in actual use: Although the demineralized water high-efficiency carbon dioxide stripping equipment can conveniently remove free carbon dioxide from water by gas-liquid desorption, the packing layer is fixedly installed in the tank, and the water will generate a large impact force when falling, so the impact force will be completely absorbed by the packing layer, which will easily accelerate the loosening rate between the packing layer and the tank. In severe cases, it can also easily wash away and damage the packing layer, resulting in poor stability in use.

[0005] To address these issues, we designed a demineralized water and carbon dioxide removal device. Utility Model Content

[0006] The purpose of this invention is to provide a demineralized water and carbon dioxide removal device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a demineralized water and carbon dioxide removal device, including a treatment tank. A packing layer is slidably arranged inside the treatment tank. A buffer member is fixedly installed on the inner side wall of the treatment tank. A T-shaped member is slidably arranged inside the buffer member. The top end of the T-shaped member slidably passes through the buffer member and is fixedly connected to the bottom of the packing layer. A damping cylinder and a support spring are arranged at the bottom of the T-shaped member. The other end of the damping cylinder and the support spring are arranged inside the buffer member. The support spring is movably sleeved on the damping cylinder.

[0008] Furthermore, the number of buffer components is two, and the two buffer components are symmetrically arranged on both sides of the inner wall of the processing tank.

[0009] Furthermore, the buffer component has a fixed cavity and a sliding opening respectively inside and at the top. The fixed cavity and the sliding opening are connected. The T-shaped component is slidably connected in the fixed cavity. The top end of the T-shaped component is slidably inserted into the sliding opening. The damping cylinder and the support spring are both located on the bottom wall of the fixed cavity at the ends away from the T-shaped component.

[0010] Furthermore, a limiting rail is provided inside the buffer component, the limiting rail is connected to the fixed cavity, the side of the T-shaped component is fixedly installed with the limiting component, and a ball is rotatably provided on one side of the limiting component, the ball being rotatably connected to the limiting rail.

[0011] Furthermore, there are two limiting rails, and the two limiting rails are symmetrically arranged inside the buffer, with the number of limiting rails corresponding to the number of limiting components.

[0012] Furthermore, the limiting member has a cavity and a through hole on its interior and one side, respectively. The cavity and the through hole are connected. The ball is rotatably disposed in the cavity and the through hole, and part of it is located outside the through hole.

[0013] Furthermore, a drainage hole is provided at the bottom of one side of the buffer member, and the drainage hole is connected to the fixing cavity.

[0014] Furthermore, a spray head is provided inside the treatment tank, a water injection pipe is fixedly inserted into the top of one side of the treatment tank, one end of the water injection pipe is fixedly connected to the spray head, an air injection pipe is fixedly inserted into the bottom of the treatment tank on the side away from the water injection pipe, a drain pipe is fixedly inserted into the bottom of the treatment tank on the side close to the water injection pipe, and an exhaust port is opened on the top of one side of the treatment tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: when water washes over the packing layer, the packing layer will drive the T-shaped part to slide downward in the fixed cavity. During this process, the support spring will shorten and absorb the impact force. After the impact force is completely absorbed, the support spring can slowly rebound in conjunction with the damping cylinder. Repeating this process can achieve the effect of buffering the packing layer, which not only improves the stability of the packing layer during use, but also helps to extend the service life of the packing layer.

[0016] Compared with the prior art, the beneficial effects of this utility model are: during the up-and-down movement of the T-shaped part in the buffer, the T-shaped part will drive the limiting part and the ball to roll in the limiting rail. This not only limits the sliding direction of the T-shaped part, but also changes the sliding friction of the T-shaped part in the buffer to rolling friction, reducing the friction force and thus reducing friction loss.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a demineralized water and carbon dioxide removal device, including a treatment tank 1. A packing layer 2 is slidably arranged inside the treatment tank 1. A buffer 3 is fixedly installed on the inner side wall of the treatment tank 1. A T-shaped part 4 is slidably arranged inside the buffer 3. The top end of the T-shaped part 4 slides through the buffer 3 and is fixedly connected to the bottom of the packing layer 2. A damping cylinder 5 and a support spring 6 are arranged at the bottom of the T-shaped part 4. The other end of the damping cylinder 5 and the support spring 6 are arranged inside the buffer 3. The support spring 6 is movably sleeved on the damping cylinder 5. A spray head 13 is arranged inside the treatment tank 1. A water injection pipe 14 is fixedly inserted into the top of one side of the treatment tank 1. One end of the water injection pipe 14 is fixedly connected to the spray head 13. An air injection pipe 15 is fixedly inserted into the bottom of the side of the treatment tank 1 away from the water injection pipe 14. A drain pipe 16 is fixedly inserted into the bottom of the side of the treatment tank 1 close to the water injection pipe 14. An exhaust port is opened on the top of one side of the treatment tank 1.

[0024] In practice, the blower is first connected to the air injection pipe 15, and then air is drawn into the treatment tank 1 through the air injection pipe 15. At the same time, water is injected into the water injection pipe 14. At this time, the water falls through the spray head 13 and enters the packing layer 2 with the air and comes into contact with it, so that the free carbon dioxide in the water is quickly released and enters the air. It is discharged with the air through the exhaust port opened on one side of the treatment tank 1. The degassed water is discharged through the drain pipe 16 to a designated location outside the treatment tank 1 for later use. This can easily achieve the effect of demineralized water and carbon dioxide removal.

[0025] See Figure 1-4 There are two buffer elements 3, which are symmetrically arranged on both sides of the inner wall of the processing tank 1. The arrangement of two buffer elements 3 can ensure that the two ends of the bottom of the packing layer 2 are subjected to balanced forces, thereby improving the stability of the packing layer 2 when sliding and avoiding the problem of the buffer elements 3 tilting.

[0026] See Figure 1-4 The buffer component 3 has a fixed cavity 7 and a sliding opening 8 on its interior and top, respectively, which are connected. The T-shaped component 4 is slidably connected in the fixed cavity 7, and its top end is slidably inserted into the sliding opening 8. The damping cylinder 5 and the support spring 6, at their ends away from the T-shaped component 4, are both located on the bottom wall of the fixed cavity 7. This facilitates the movement of the internal components of the buffer component 3 and avoids motion interference.

[0027] See Figure 1-4 A limiting rail 9 is provided inside the buffer 3. The limiting rail 9 is connected to the fixed cavity 7. The side of the T-shaped part 4 is fixedly installed with the limiting part 10. A ball bearing 11 is rotatably provided on one side of the limiting part 10. The ball bearing 11 is rotatably connected in the limiting rail 9. A cavity and a through hole are respectively provided inside and on one side of the limiting part 10. The cavity and the through hole are connected. The ball bearing 11 is rotatably provided in the cavity and the through hole, and part of it is located outside the through hole.

[0028] In specific implementation, based on the above implementation, during the up-and-down movement of the T-shaped part 4 within the buffer part 3, the T-shaped part 4 will drive the limiting part 10 and the ball 11 to roll within the limiting rail 9. This not only limits the sliding direction of the T-shaped part 4, but also changes the sliding friction of the T-shaped part 4 within the buffer part 3 into rolling friction, reducing friction and thus reducing friction loss.

[0029] See Figure 1-4 There are two limiting rails 9, which are symmetrically arranged inside the buffer 3. The number of limiting rails 9 corresponds to the number of limiting parts 10. The arrangement of two limiting rails 9 can ensure that the forces on both sides of the T-shaped part 4 are balanced, thereby improving the stability of the T-shaped part 4 during use.

[0030] See Figure 1-4A drainage hole 12 is provided at the bottom of one side of the buffer 3, and the drainage hole 12 is connected to the fixed cavity 7. This allows water that has seeped into the fixed cavity 7 to be effectively drained, preventing water from affecting the movement of the internal components of the buffer 3.

[0031] Working principle: Before use, first connect the blower to the air injection pipe 15, and then draw air into the treatment tank 1 through the air injection pipe 15. At the same time, inject water into the water injection pipe 14. At this time, the water falls through the spray head 13 and enters the packing layer 2 with the air and comes into contact with it, so that the free carbon dioxide in the water is quickly released and enters the air. It is discharged with the air through the exhaust port opened on one side of the treatment tank 1. The degassed water is discharged through the drain pipe 16 to the designated location outside the treatment tank 1 for later use. This can easily achieve the effect of demineralized water and carbon dioxide removal.

[0032] During the above operation, when water washes over the packing layer 2, the packing layer 2 will cause the T-shaped part 4 to slide downward in the fixed cavity 7. During this process, the support spring 6 will shorten and absorb the impact force. After the impact force is completely absorbed, the support spring 6 can slowly rebound in conjunction with the damping cylinder 5. Repeating this process can achieve the effect of buffering the packing layer 2, which not only improves the stability of the packing layer 2 during use, but also helps to extend the service life of the packing layer 2.

[0033] In addition, during the up-and-down movement of the T-shaped part 4 within the buffer 3, the T-shaped part 4 will drive the limiting part 10 and the ball 11 to roll within the limiting rail 9. This not only limits the sliding direction of the T-shaped part 4, but also changes the sliding friction of the T-shaped part 4 within the buffer 3 into rolling friction, reducing friction and thus reducing friction loss.
