[0002] During the production process of the chemical industry, a large amount of gas-liquid mixtures containing low-boiling-point chemical components are generated. If these chemical components are not properly handled, they will cause environmental pollution.

[0003] At present, traditional gas-liquid separators mostly use gravity and circulation separation methods, relying solely on the gravity difference of the medium to achieve gas-liquid separation, resulting in low separation efficiency and incomplete separation. The separation equipment in the existing technology is difficult to throw out the liquid through rotation, and it is not convenient to quickly separate the bubbles in the liquid, which needs further improvement. Utility Model Content

[0004] In order to overcome the problem that the separation equipment in the prior art is difficult to throw out the liquid through the rotation action and is not convenient to quickly separate the bubbles in the liquid, a rotary separation equipment for gas-liquid separation is proposed.

[0005] The technical solution of the utility model is: a rotary separation device for gas-liquid separation, comprising a cylinder, a bottom block fixed to the lower end of the cylinder, and a storage box arranged on the bottom block, wherein the lower end of the bottom block is fixed to an inclined platform, and the upper end of the bottom block is provided with a pump body for extracting liquid from the storage box;

[0006] An infusion tube is provided inside the cylinder, the output end of the pump body is connected to the input end of the infusion tube, and an electromagnetic valve is provided at the output end of the infusion tube;

[0007] The side wall of the infusion tube is penetrated by a second water outlet hole distributed equidistantly along the axial direction;

[0008] A bracket is fixedly connected to the inner wall of the cylinder, and a fixed cylinder is rotatably provided on the bracket. The fixed cylinder is located outside the infusion tube, and the central axes of the fixed cylinder and the infusion tube are collinear;

[0009] The side wall of the fixed cylinder is penetrated by a first water outlet hole which is evenly distributed along the axial direction. A water-absorbing spiral cotton column is fixed to the side wall of the fixed cylinder. The side wall of the water-absorbing spiral cotton column blocks the liquid outlet end of the first water outlet hole.

[0010] The bracket is provided with a driving mechanism for rotating the fixed cylinder.

[0011] Furthermore, the other end of the infusion tube is connected to a return water mechanism, which includes a return water pipe fixedly connected to the other end of the infusion tube and a plurality of third water outlet holes penetrating the side wall of the return water pipe. The plurality of third water outlet holes are evenly distributed along the axial direction of the return water pipe, and the water outlet ends of the third water outlet holes face the outer wall of the water-absorbing spiral cotton column.

[0012] Furthermore, a liquid receiving device is installed at the lower end of the cylinder, and the liquid receiving device is U-shaped with an opening facing upward.

[0013] Furthermore, a reinforcement support is fixedly connected to the bottom surface of the inner wall in contact with the liquid, and a side wall of the liquid delivery tube is fixedly connected to the reinforcement support.

[0014] Furthermore, the driving mechanism includes a frame fixed to the bracket, a motor fixed to the frame, a gear fixed to the output shaft of the motor, and a gear ring fixed to the side wall of the fixed cylinder, and the gear ring and the gear are meshed with each other.

[0015] Furthermore, the distance between the side wall of the fixed cylinder and the outer wall of the infusion tube is less than ten centimeters.

[0016] Furthermore, a flow guiding mechanism is provided in the cylinder, which includes a connecting block fixed to the inner wall of the cylinder and a flow guiding plate fixed to the side wall of the connecting block. The flow guiding plate is arc-shaped and is located outside the fixed cylinder.

[0017] Furthermore, the guide plate is half the shape of the cylinder, and the central axis of the guide plate and the central axis of the fixed cylinder are collinear.

[0018] Beneficial effects of the utility model:

[0019] 1. By setting a driving mechanism, a fixed cylinder and a water-absorbing spiral cotton column, when the motor of the driving mechanism is working, its output shaft drives the gear to rotate, and the gear engages with the gear ring to drive the fixed cylinder to rotate on the bracket. When the pump body draws the liquid in the storage box into the infusion tube, the liquid flows out from the second water outlet hole, and then the fixed cylinder rotates to throw the liquid out through the first water outlet hole on the fixed cylinder. Finally, the liquid will be absorbed by the water-absorbing spiral cotton column on the side wall of the fixed cylinder. As the fixed cylinder rotates, the water-absorbing spiral cotton column rotates synchronously. Under the action of centrifugal force, the liquid absorbed in the water-absorbing spiral cotton column is quickly thrown out, realizing the rotary throwing of the liquid, replacing the traditional method of relying solely on gravity separation, and improving the initiative and efficiency of liquid separation.

[0020] 2. By setting up the rotating structure of the water-absorbing spiral cotton column and the fixed cylinder and cooperating with the first water outlet hole and the second water outlet hole, the rapid separation of bubbles in the liquid is achieved. When the liquid seeps out through the second water outlet hole of the infusion tube, it is first absorbed by the water-absorbing spiral cotton column. Under the centrifugal force generated by the rotation of the fixed cylinder, the liquid is subjected to an outward throwing force in the water-absorbing spiral cotton column. During this process, the bubbles inside the liquid are less dense than the liquid and will quickly move outward and burst under the action of the centrifugal force. At the same time, the fiber structure of the water-absorbing spiral cotton column can also accelerate the discharge of bubbles, thereby solving the problem of inconvenience in quickly separating bubbles in the liquid.

[0021] 3. By setting up a return water mechanism, the return water pipe and the third water outlet hole connected to the output end of the infusion tube, opening the solenoid valve, part of the liquid can flow into the return water pipe and then flow out from the third water outlet hole, effectively improving the gas-liquid separation effect.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1: Please refer to Figures 1-8 The rotary separation device for gas-liquid separation comprises a cylinder 1, a bottom block 2 fixed to the lower end of the cylinder 1, and a storage box 3 provided on the bottom block 2. The lower end of the bottom block 2 is fixed to an inclined platform 19, and the upper end of the bottom block 2 is provided with a pump body 4 for extracting liquid from the storage box 3.

[0033] A liquid infusion tube 9 is provided inside the cylinder 1, the output end of the pump body 4 is connected to the input end of the liquid infusion tube 9, and a solenoid valve 13 is provided at the output end of the liquid infusion tube 9;

[0034] The side wall of the liquid infusion tube 9 is penetrated by second water outlet holes 10 distributed equidistantly along the axial direction;

[0035] A bracket 5 is fixedly connected to the inner wall of the cylinder 1, and a fixed cylinder 6 is rotatably provided on the bracket 5. The fixed cylinder 6 is located outside the infusion tube 9, and the central axes of the fixed cylinder 6 and the infusion tube 9 are collinear.

[0036] The side wall of the fixed cylinder 6 is penetrated by a first water outlet hole 7 distributed equidistantly along the axial direction, and a water-absorbing spiral cotton column 8 is fixedly connected to the side wall of the fixed cylinder 6. The side wall of the water-absorbing spiral cotton column 8 blocks the liquid outlet end of the first water outlet hole 7;

[0037] The bracket 5 is provided with a driving mechanism for rotating the fixed cylinder 6 .

[0038] When in use, the driving mechanism is turned on to rotate the fixed cylinder 6, and the pump body 4 is turned on to draw the liquid in the storage box 3 into the infusion tube 9, and the liquid will flow out through the second water outlet 10. Since the fixed cylinder 6 is in a rotating state, the fixed cylinder 6 will throw the liquid that falls on the inner wall of the fixed cylinder 6 outward through the first water outlet 7 to the water-absorbing spiral cotton column 8. After the liquid is adsorbed by the water-absorbing spiral cotton column 8, it drips downward due to gravity. Then, due to the inclination of the inclined platform 19, the liquid flows out along the bottom surface of the inner wall of the cylinder 1 to the lower side, and the air in the liquid is separated from the liquid due to the adsorption of the water-absorbing spiral cotton column 8, which solves the problem that the separation equipment in the prior art is difficult to throw out the liquid through rotation and is inconvenient to quickly separate the bubbles in the liquid.

[0039] See also Figure 1 and Figure 4 In this embodiment, a liquid receiving device 14 is installed at the lower end of the cylinder 1. The liquid receiving device 14 is U-shaped and opens upward. The U-shaped liquid receiving device 14 with an upward opening can effectively receive the liquid flowing from above, prevent water from spilling, and provide a stable receiving foundation for subsequent structures.

[0040] See also Figure 2 and Figure 4 In this embodiment, a reinforcement support 15 is fixedly connected to the bottom surface of the inner wall of the liquid receiving device 14, and the side wall of the infusion tube 9 is fixedly connected to the reinforcement support 15. The reinforcement support 15 provides a stable support for the infusion tube 9, which can enhance the stability of the installation of the infusion tube 9, prevent the infusion tube 9 from shaking or displacement due to its own weight or water impact, and ensure a smooth infusion process.

[0041] See also Figure 1 and Figure 6In this embodiment, the driving mechanism includes a frame fixed to the bracket 5, a motor 16 fixed to the frame, a gear 17 fixed to the output shaft of the motor 16, and a gear ring 18 fixed to the side wall of the fixed cylinder 6. The gear ring 18 and the gear 17 are engaged with each other. The motor 16 drives the gear 17 to rotate, and the gear 17 engages with the gear ring 18 to drive the fixed cylinder 6 to rotate, which can more accurately control the rotation state of the fixed cylinder 6.

[0042] See also Figure 1 and Figure 2 In this embodiment, the distance between the side wall of the fixed cylinder 6 and the outer wall of the infusion tube 9 is less than ten centimeters. The smaller distance can reduce the space waste between the two, making the structural layout more compact, and at the same time it is beneficial to shorten the water flow transmission path and make the liquid flow down more quickly.

[0043] Example 2: Please refer to Figure 3 On the basis of Example 1, the present application provides a technical solution: the other end of the infusion tube 9 is connected to a water return mechanism, the water return mechanism includes a water return pipe 11 fixedly connected to the other end of the infusion tube 9 and a plurality of third water outlet holes 12 penetrating the side wall of the water return pipe 11, the plurality of third water outlet holes 12 are evenly distributed along the axial direction of the water return pipe 11, the water outlet ends of the third water outlet holes 12 face the outer wall of the water-absorbing spiral cotton column 8, the water return mechanism can return the water in the infusion tube 9 to the water-absorbing spiral cotton column 8 through the water return pipe 11 and the third water outlet holes 12, the evenly distributed third water outlet holes 12 can make the water flow evenly sprayed on the outer wall of the water-absorbing spiral cotton column 8, ensuring that the water-absorbing spiral cotton column 8 evenly absorbs water, and facilitating the separation of gas in the liquid.

[0044] Example 3: Please refer to Figure 8 Based on Example 1, the present application provides a technical solution: a flow guide mechanism is provided in the cylinder 1, and the flow guide mechanism includes a connecting block 20 fixedly connected to the inner wall of the cylinder 1 and a guide plate 21 fixedly connected to the side wall of the connecting block 20. The guide plate 21 is arc-shaped and is located outside the fixed cylinder 6. The arc-shaped guide plate 21 can guide the water flow in the cylinder 1, change its flow direction, avoid turbulence, improve the orderliness of the fluid flow, and help improve the overall working efficiency of the equipment.

[0045] See also Figure 1 and Figure 8 In this embodiment, the guide plate 21 is one-half of a cylinder, and the central axis of the guide plate 21 is collinear with the central axis of the fixed cylinder 6. The structural design of one-half of the cylinder is collinear with the central axis of the fixed cylinder 6, so that the guide plate 21 can more accurately guide the fluid outside the fixed cylinder 6. The diversion range is moderate and highly targeted, further optimizing the fluid flow state and making it more coordinated with the fixed cylinder 6.

[0046] Working principle: When in use, turn on the motor 16 in the drive mechanism, the motor 16 drives the gear 17 to rotate, the gear 17 engages with the gear ring 18 and drives the fixed cylinder 6 to rotate on the bracket 5, and at the same time, turn on the pump body 4 to draw the liquid in the storage box 3 into the infusion tube 9. Part of the liquid flows out through the second water outlet 10 on the side wall of the infusion tube 9 and falls on the inner wall of the fixed cylinder 6. Because the fixed cylinder 6 is in a rotating state, it throws the liquid on the inner wall outward through the first water outlet 7 to the water-absorbing spiral cotton column 8, and the other part of the liquid can directly flow back to the water-absorbing spiral cotton column 8 through the third water outlet 12 on the side wall of the return pipe 11 On the outer wall, the liquid is absorbed by the water-absorbing spiral cotton column 8 and drips downward due to gravity. During the dripping process, it is guided by the arc-shaped guide plate 21 and finally falls into the liquid receiving area 14. Then, it flows out along the inclined direction of the inclined platform 19 and the bottom surface of the inner wall of the cylinder 1 to the lower side. The air in the liquid is separated from the liquid during the adsorption process by the water-absorbing spiral cotton column 8. The reinforced support 15 plays a role in firmly supporting the infusion tube 9. The solenoid valve 13 can control the on and off of the output end of the infusion tube 9, thereby realizing efficient separation of gas and liquid. A container is placed at the liquid outlet end of the liquid receiving area 14 to receive the liquid after the gas is separated.
