Technical Field

[0001] The present invention relates to the technical field of gas-liquid separation equipment, and particularly to a gas-liquid separation component with a multi-layer demisting structure. Background Art

[0002] During the gas-liquid separation process, it is usually necessary to pass a high-temperature gas stream through a wire mesh layer, so that the steam carrying water droplets impacts on the wire mesh and adheres to it. As the water droplets gather, they form liquid droplets, achieving the purpose of filtering the gas stream.

[0003] In the prior art, CN103977665B discloses a gas-liquid separator, which includes: a cylinder body, an air inlet pipe is connected to the outer wall of the cylinder body along its horizontal tangent direction, and an air outlet pipe is connected to the upper end of the cylinder body; a cyclone separation component, arranged inside the cylinder body, including a spiral plate that spirally extends from the inner wall of the cylinder body towards the center to form a spiral channel, and the air inlet pipe is communicated with the spiral channel; a wire mesh part, arranged inside the cylinder body and above the cyclone separation component; a liquid discharge component, arranged inside the cylinder body and below the cyclone separation component to discharge the separated liquid. The gas-liquid separator provided by the present invention efficiently completes gas-liquid separation.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figures 1 to 8 , the present invention provides a technical solution: a gas-liquid separation component with a multi-layer demisting structure, including a demisting tank 1, a feed inlet 2 is arranged on one side of the demisting tank 1, a necking port is arranged at the upper end of the demisting tank 1, an end cover 3 is arranged at the upper end of the necking port, a wire mesh layer 10 is arranged in the necking port, an exhaust port 9 for exhaust is arranged on the end cover 3, the wire mesh layer 10 is rotatably installed in the inner cavity of the demisting tank 1, a rotating pipe 7 driven by a motor 4 is arranged on the end cover 3, the wire mesh layer 10 is fixedly sleeved on the rotating pipe 7, a plurality of conical blanking hoods 23 are arranged in the middle section of the rotating pipe 7, a plurality of opening grooves 20 distributed in a circumferential array are arranged on the conical end surface of the conical blanking hood 23, a flexible strip 15 fixed on one side is arranged on the opening groove 20, a lifting rod 8 controlled in height by a telescopic rod 5 is slidably inserted into the rotating pipe 7, a bottom plate 13 is arranged at the lower end of the lifting rod 8, a connecting rod 14 is connected between the flexible strips 15 on the upper and lower adjacent conical blanking hoods 23, the connecting rod 14 is located on one side of the free end of the flexible strip 15, and the lower end of the connecting rod 14 close to the bottom plate 13 is connected to the bottom plate 13.

[0030] The high-temperature raw material enters the lower inner cavity of the demisting tank 1 through the feed inlet 2, so that the high-temperature airflow with water droplets rises, the airflow impacts on the conical blanking hood 23, so that the water droplets gather and adhere, and the airflow rises along the gap between the flexible strip 15 and the opening groove 20 and enters the wire mesh layer 10, so that the water droplets in the airflow are fully filtered and adhered in the gaps of the wire mesh.

[0031] When the rotating pipe 7 does not rotate, the filtration speed is slow, water droplets adhere to the gaps in the wire mesh, and the rate of aggregation into drops is slow, resulting in the blockage of the wire mesh gaps by water droplets, thereby further reducing the filtration efficiency. At this time, the motor is used to drive the rotation of the rotating pipe 7. As the wire mesh layer 10 rotates, a centrifugal force is formed, causing the water droplets to accelerate aggregation and impact and remain on the inner wall of the demisting tank 1, avoiding blockage of the wire mesh.

[0032] When more dry air flow is required in production, at this time, the telescopic rod 5 is used to drive the lifting rod 8 to rise. The lifting rod 8 drives the connecting rod 14 to rise, thereby driving one end of the flexible strip 15 to lift upward, causing the flexible strip 15 to deform and bend upward, increasing the opening gap of the opening groove 20 and increasing the flow rate. At the same time, as the rotating pipe 7 rotates, it drives the conical blanking cover 23 and the flexible strip 15 to rotate. At this time, the flexible strip 15 is equivalent to a fan blade, extracting the steam at the lower end upward, increasing the upward speed of the air flow, and thus achieving the purpose of improving the filtration wind efficiency.

[0033] Example 2: Please refer to Figure 5 , on the basis of Example 1, the rotating pipe 7 extends to the upper end of the end cover 3. A driven gear 26 is fixedly sleeved on the upper end of the rotating pipe 7. A driving gear 25 driven by a motor 4 is arranged on one side of the end cover 3. The driving gear 25 is meshed and connected with the driven gear 26. A cover plate 6 is arranged on the end cover 3 and pressed on the driven gear 26. The cover plate 6 is fixed to the end cover 3 by screws. An upper frame is arranged on the cover plate 6, and a telescopic rod 5 is installed on the upper frame. One end of the telescopic rod 5 is connected to the upper frame, and the other end of the telescopic rod 5 is rotationally connected to the end of the lifting rod 8 by a bearing.

[0034] By setting the meshing transmission between the gears, the purpose of driving the rotating rod 7 to rotate is achieved. By using the cooperation of the cover plate and the upper frame, the fixed installation of the telescopic rod 5 is realized, and further the purpose of driving the lifting rod 8 is achieved, making the lifting of the lifting rod 8 independent of the rotation of the rotating pipe 7.

[0035] Please refer to Figure 5 , a first spring 24 is sleeved on the lifting rod 8. The lower end of the first spring 24 is pressed on the upper end of the rotating pipe 7, and the upper end of the first spring 24 abuts against the end of the lifting rod 8.

[0036] The elastic connection between the lifting rod 8 and the rotating pipe 7 is realized by setting the first spring 24.

[0037] Example 3: Please refer to Figure 7 、 8 , on the basis of Example 2, grids 31 are arranged at both the upper and lower ends of the wire mesh layer 10. A gas guide cover 11 is fixedly installed on the grid 31 at the lower end of the wire mesh layer 10. There is an annular gap between the inner wall of the gas guide cover 11 and the outer wall of the rotating pipe 7. The lower end of the gas guide cover 11 extends into the middle section inner cavity of the demisting tank 1. A plurality of groups of air holes 33 distributed in a circumferential array and communicating with the wire mesh layer 10 are arranged on the gas guide cover 11.

[0038] By setting the cooperation of the air guide cover 11 and the air holes 33, the air flow is evenly guided into the wire mesh layer 10.

[0039] On the left and right sides of the air guide cover 11, there are inserted slots 30. In the inserted slots 30, there are inserted plates 12 elastically. On a pair of inserted plates 12 distributed left and right, there are micropores 28 corresponding to the air holes 33 one by one. Between the end of the inserted plate 12 and the inner wall of the end of the inserted slot 30, there is a second spring 29 pressed. The inner diameters of the micropores 28 and the air holes 33 are the same. The elastic deformation length of the second spring 29 is greater than the inner diameter of the micropores 28. There is a jack 27 on the inserted plate 12, and there is a positioning hole 32 corresponding to the jack 27 on the air guide cover 11. In the positioning hole 32, there is a single-sided tapered rod 17 slidably inserted. The upper small diameter of the single-sided tapered rod 17 fits the side wall of the positioning hole 32, and the lower large diameter of the single-sided tapered rod 17 is the same as the inner diameter of the positioning hole 32.

[0040] By setting the second spring 29, the elastic installation of the inserted plate 12 is realized. Under the limit of the reset elastic force of the single-sided tapered rod 17 and the second spring 29, the micropores 28 are aligned with the air holes 33, so that the air flow can enter the wire mesh layer 10 along the air holes 33. When the single-sided tapered rod 17 rises, by the extrusion of the inclined surface of the single-sided tapered rod 17, the purpose of laterally extruding the inserted plate 12 is achieved, so that the micropores 28 are misaligned with the air holes 33, and the purpose of blocking the air guide cover 11 is achieved. So that the air flow, under the action of the air guide cover 11, enters the wire mesh layer 10 along the circular ring gap between the air guide cover 11 and the rotating pipe 7, reducing the flow area and increasing the flow velocity of the air flow, so that the air flow impacts from the center to the outside of the wire mesh layer 10. During the impact process, the purpose of impacting water droplets and accelerating aggregation is achieved. Therefore, when the rotating pipe 7 does not rotate, only by raising and lowering the lifting rod 8, the air flow circulation speed is increased, and the purpose of reducing blockage is achieved.

[0041] Example 4: Please refer to Figure 2 , on the basis of Example 3, at the end of the connecting rod 14 on the conical blanking cover 23 close to the air guide cover 11, there is a double-headed rotating rod 18 rotatably connected. The lower end of the single-sided tapered rod 17 extends to the outside of the lower end of the positioning hole 32, and the other end of the double-headed rotating rod 18 is rotatably connected to the lower end of the single-sided tapered rod 17.

[0042] In order to ensure that during the rising process of the lifting rod 8, the single-sided tapered rod 17 is lifted and lowered by the connecting rod 14, the double-headed rotating rod 18 is set. Through the two-way rotating installation of the double-headed rotating rod 18, it adapts to the bending deformation of the flexible strip 15.

[0043] The inner wall of the middle section of the demisting tank 1 is provided with a support ring 19. An outer ring 16 is provided on the outer edge of the conical blanking cover 23. The outer ring 16 is rotatably mounted on the support ring 19. A limiting ring 21 is inserted and mounted on the support ring 19. The limiting ring 21 is fixed to the support ring 19 by a fixing member 22. The outer ring 16 is rotatably clamped between the support ring 19 and the limiting ring 21.

[0044] By providing the support ring 19 and the limiting ring 21, the purpose of limiting the position of the outer ring 16 is achieved, ensuring the limited rotation of the conical blanking cover 23.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
