Description

Technical Field

[0001] This utility model relates to the field of steam-water separation technology, and in particular to a steam-water separator. Background Technology

[0002] A steam-water separator is a device used to separate steam from liquid water in a mixture of steam and water. It is widely used in industrial processes, especially in applications that require pure steam or dry air. The main function of a steam-water separator is to remove moisture from steam to improve steam quality, reduce corrosion and wear on downstream equipment, and improve thermal efficiency.

[0003] Existing steam-water separators use centrifugal separation with spiral guide vanes, which has certain drawbacks. Even at high speeds, the centrifugal force may not be sufficient to completely separate very small droplets, causing some tiny droplets to flow out with the steam and affecting the steam quality. Therefore, we propose a steam-water separator to solve this problem. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a steam-water separator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gas-water separator includes a separating tank. A partition is fixedly installed on the inner wall of the separating tank. A rotating shaft and two worm gears are rotatably installed on the top and left and right sides of the partition, respectively. A bevel gear is fixedly installed at one end of each rotating shaft and worm gear. The three bevel gears mesh sequentially. A circular plate is vertically and slidably sealed inside the separating tank. Two fixed plates are fixedly installed on the inner wall of the separating tank. A worm wheel is rotatably installed on the front side of the fixed plate. The worm gear meshes with the corresponding worm wheel. A cylinder is fixedly installed on the front edge of the worm wheel. An inclined connecting plate is fixedly installed on the outer side of the cylinder. The bottom plate of the connecting plate is rotatably connected to the top of the circular plate. An annular plate is fixedly installed on the inner wall of the separating tank. Multiple insert plates are fixedly installed on the bottom of the annular plate. Multiple through holes are opened on the top of the circular plate. The insert plates are adapted to the through holes. A motor is fixedly installed on the outer side of the separating tank. The motor is fixedly connected to the worm gear located on the right side.

[0007] Preferably, a rotating sleeve is rotatably installed on the inner wall of the top of the separator, a spiral guide ring is fixedly installed on the outer side of the rotating sleeve, a pneumatic valve pipe is connected to the top of the separator, the pneumatic valve pipe is slidably sealed to the rotating sleeve, the pneumatic valve pipe is connected to the rotating sleeve, and an air outlet pipe is connected to the outer side of the pneumatic valve pipe.

[0008] Preferably, a control plate and a lifting plate are vertically slidably installed inside the pneumatic valve pipe, a hydraulic cylinder is fixedly installed on the top of the pneumatic valve pipe, the output end of the hydraulic cylinder is fixedly connected to the top of the control plate, and multiple support springs are fixedly connected between the control plate and the lifting plate.

[0009] Preferably, a plurality of conical cylinders are fixedly installed on the outer side of the rotating shaft, the conical cylinders are fixedly connected to the inner wall of the rotating sleeve, and the conical cylinders are provided with a plurality of leakage holes.

[0010] Preferably, the inner wall of the separation tank is provided with multiple vertical grooves, multiple guide plates are fixedly installed on the outer side of the circular plate, the guide plates are slidably and sealingly installed in the corresponding vertical grooves, and a conical plate is fixedly installed at the top center of the circular plate.

[0011] Preferably, the bottom of the separator is funnel-shaped, a drainage mechanism is provided at the bottom of the separator, an air inlet pipe is connected to the outside of the separator, and control valves are provided on both the air inlet pipe and the air outlet pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] The rotating shaft drives the rotating sleeve and the guide ring to rotate together, forming a rotating airflow to centrifugally separate the steam and water mixture. The holes on the multiple conical cylinders increase in size from top to bottom, achieving multi-stage interception of moisture in the steam, thereby improving the rate and effect of steam-water separation.

[0014] The worm gear and connecting plate work together to drive the circular plate to move up and down. As the circular plate moves upward, the insert plate enters the through hole and seals it. The part above the circular plate in the separator forms a sealed space. As the circular plate moves upward, the pressure in the sealed space increases continuously, and the water in the separator is more likely to accumulate, thus improving the centrifugal separation effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A gas-water separator includes a separator tank 1. A partition box 2 is fixedly installed on the inner wall of the separator tank 1. A rotating shaft 3 and two worm gears 4 are rotatably installed on the top and left and right sides of the partition box 2, respectively. A bevel gear is fixedly installed at one end of the rotating shaft 3 and the worm gears 4. The three bevel gears mesh in sequence. A circular plate 5 is vertically and slidably sealed inside the separator tank 1. Two fixed plates are fixedly installed on the inner wall of the separator tank 1. A worm wheel 6 is rotatably installed on the front side of the fixed plate. The worm gears 4 mesh with the corresponding worm wheels 6. A cylinder 7 is fixedly installed on the front edge of the worm wheel 6. An inclined connecting plate 8 is fixedly installed on the outer side of the cylinder 7. The bottom plate of the connecting plate 8 is rotatably connected to the top of the circular plate 5. An annular plate 9 is fixedly installed on the inner wall of the separator tank 1. Multiple insert plates 10 are fixedly installed on the bottom of the annular plate 9. Multiple through holes 11 are opened on the top of the circular plate 5. The insert plates 10 are adapted to the through holes 11. A motor 12 is fixedly installed on the outer side of the separator tank 1. The motor 12 is fixedly connected to the worm gear 4 located on the right side.

[0023] like Figure 2 As shown, a rotating sleeve 13 is rotatably installed on the inner wall of the top of the separator 1, and a spiral guide ring 14 is fixedly installed on the outer side of the rotating sleeve 13. The top of the separator 1 is connected to a pressure valve pipe 15, which is slidably sealed to the rotating sleeve 13. The pressure valve pipe 15 is connected to the rotating sleeve 13, and an air outlet pipe 25 is connected to the outer side of the pressure valve pipe 15.

[0024] It should be noted that the motor 12 drives the right worm 4 to rotate. The worm 4, through its cooperation with the bevel gear, drives the rotating shaft 3 and the left worm 4 to rotate, thereby driving the rotating sleeve 13 and the guide ring 14 to rotate together, forming a rotating airflow to centrifugally separate the steam and water mixture. The steam and water mixture enters from the side of the separator 1, which immediately generates rotational motion. Under the action of centrifugal force, the denser water droplets are pushed towards the inner wall of the separator 1, while the lighter steam concentrates in the central part of the separator 1 and then flows out from the top of the separator 1, thus obtaining relatively dry steam.

[0025] like Figure 4 As shown, a control plate 16 and a lifting plate 17 are vertically slidably installed inside the pneumatic valve pipe 15. A hydraulic cylinder 19 is fixedly installed on the top of the pneumatic valve pipe 15. The output end of the hydraulic cylinder 19 is fixedly connected to the top of the control plate 16. Multiple support springs 18 are fixedly connected between the control plate 16 and the lifting plate 17.

[0026] It should be noted that a guide mechanism for the lifting plate 17 is provided inside the air pressure valve pipe 15, which guides the vertical movement of the lifting plate 17, making the lifting plate 17 move smoothly. At the lowest point, the lifting plate 17 is supported by the support plate on the inner wall of the air pressure valve pipe 15. The hydraulic cylinder 19 drives the control plate 16 to move downward to compress the support spring 18, so as to adjust the degree of compression of the support spring 18 to control the maximum air pressure in the separation tank 1.

[0027] like Figure 2 and Figure 3 As shown, multiple conical cylinders 20 are fixedly installed on the outer side of the rotating shaft 3. The conical cylinders 20 are fixedly connected to the inner wall of the rotating sleeve 13, and multiple leakage holes are opened on the conical cylinders 20.

[0028] It should be noted that the leakage holes on the multiple conical cylinders 20 increase in size from top to bottom, with the bottommost hole being the largest and the topmost hole being the smallest. This achieves multi-stage interception of moisture in the steam, thereby improving the rate and effect of steam-water separation.

[0029] like Figure 3 As shown, the inner wall of the separator 1 is provided with multiple vertical grooves 21, and multiple guide plates are fixedly installed on the outer side of the circular plate 5. The guide plates are slidably and sealed in the corresponding vertical grooves 21. A conical plate 22 is fixedly installed at the top center of the circular plate 5. The guide plates on the outer side of the circular plate 5 slide in the vertical grooves 21, making the vertical movement of the circular plate 5 more stable and preventing steam from leaking through the vertical grooves 21 to the bottom of the circular plate 5.

[0030] like Figure 1 and Figure 2As shown, the bottom of the separator 1 is funnel-shaped, and a drainage mechanism 23 is provided at the bottom of the separator 1. An air inlet pipe 24 is connected to the outside of the separator 1, and control valves are provided on both the air inlet pipe 24 and the air outlet pipe 25.

[0031] The working principle of this utility model is as follows: A mixture of steam and water is introduced into the separator tank 1 through the air inlet pipe 24. The motor 12 is started, and the motor 12 drives the rotating shaft 3 and two worm gears 4 to rotate synchronously through the cooperation of the bevel gear. The rotating shaft 3 drives the rotating sleeve 13 and the guide ring 14 to rotate together, forming a rotating airflow to centrifugally separate the steam and water mixture. The separated water flows to the bottom of the circular plate 5 through multiple through holes 11. At the same time, the worm gear 4 drives two worm wheels 6 to rotate. The worm wheels 6 drive the circular plate 5 to move up and down through the cooperation of the connecting plate 8. During the upward movement of the circular plate 5, the insert plate 10 is inserted into the through hole 11 to seal the through hole 11. At this time, the drainage mechanism 23 can drain the water below the circular plate 5 and prevent external gas from entering the separator tank 1. The part above the circular plate 5 in the separator tank 1 forms a sealed space. As the circular plate 5 moves upward, the pressure in the sealed space continuously increases, and the water in the separator tank 1 is more likely to accumulate, which improves the centrifugal separation effect. The separated steam pushes the lifting plate 17 upward and is then discharged through the air outlet pipe 25.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
