Description

Technical Field

[0001] The present invention relates to the technical field related to water-vapor separation, and particularly to a water-vapor separation device for a steam boiler. Background Technique

[0002] A steam boiler is a special equipment that heats water into steam, belonging to a heat energy conversion device, and is widely used in industries, power, ships and other fields. Its core function is to heat water through fuel (such as gas, coal, oil) or electric energy to generate high-temperature and high-pressure steam to provide energy for the production or power system. In order to ensure the steam quality of the steam boiler, a steam-water separator is used to improve the steam quality. A steam-water separator is a device widely used in the industrial field, mainly used to effectively separate the two-phase substances in the gas-liquid mixture. Its core function is to separate the liquid droplets in the gas through a specific structural design and working principle, thereby improving the purity and quality of the gas. However, the small water droplets separated from the steam by the steam-water separator will hang on the rotating blades and the inner wall, and when these water droplets are disturbed by the air flow, they may splash or cause droplet re-entrainment, reducing the efficiency and effect of steam-water separation. There are also invention patents in the prior art for this problem. For example, a horizontal single-drum double-furnace assembled boiler with the application number CN202411298053.6 also proposes the above problem and completes the scraping of the liquid droplets on the rotating blades through corresponding components. However, this invention patent cannot better scrape the liquid droplets on the rotating blades and the inner wall when the steam-water separator is in use, and the scraping effect and efficiency of the liquid droplets are poor.

[0029] Beneficially, it further includes a control terminal 12 paired with the steam-water separator 11. The control terminal 12 is used to control all motors and electromagnets.

[0030] Usage method of the present invention:

[0031] In the initial state:

[0032] The control terminal 12 is set at a reasonable position. The first scraping knife 30, the second scraping knife 31, the third scraping knife 32, and the diversion groove 34 partially overlap. The limiting rope 44 is in a taut state. The second springs 37 are all in a compressed state. The first torsion spring 62 is in a tightened state. The control rope 27 and the connecting rope 26 are in a taut state. The sliding block 49 is repelled by the electromagnet 50. The clamping roller 47 does not clamp the control rope 27. The second torsion spring 57 is in a normal state. The telescopic rod 42 is in a fully retracted state. The first spring 43 is in a compressed state.

[0033] When the user wants to use this device, the user needs to connect the steam inlet 13 and the steam outlet 14 to the corresponding pipelines. The steam from the steam boiler will be introduced into the steam inlet 13 through the external pipeline and enter the spiral channel 19 from the steam inlet 13. After the steam enters the spiral channel 19, it will enter the separation space 22 along the spiral channel 19. During this process, the steam-water separation of the steam will be completed. The liquid droplets in the steam will be thrown onto the spiral channel 19 and the separation space 22 under the action of gravity. The steam that has completed the steam-water separation will enter the exhaust hole 21 and then enter the exhaust space 63, and be discharged into the steam outlet 14 through the exhaust space 63, and then discharged. After the steam has passed for a certain period of time, the control terminal 12 will drive the second motor 51 and the first motor 52 to start. After the second motor 51 starts, its motor shaft will drive the second reel 45 to rotate, so that through the rotation of the second reel 45, the winding of the connecting rope 26 will be completed, and thus drive the slider 28 to move towards the exhaust space 63. After the first motor 52 starts, its motor shaft will drive the first reel 46 to rotate, so that through the rotation of the first reel 46, the control rope 27 will be wound, so as to ensure that when the slider 28 moves, the telescopic scraping mechanism 61 remains in a contracted state until the slider 28 moves to the highest point, and the second motor 51 and the first motor 52 will stop driving. Then the first motor 52 will start. After the first motor 52 starts, it will drive the first reel 46 to rotate, so that through the rotation of the first reel 46, the control rope 27 will be loosened, so that the limiting rope 44 is no longer taut. Thus, under the action of the second spring 37, the first scraping knife 30, the second scraping knife 31, the third scraping knife 32, and the fourth scraping knife 33 start to move, the telescopic rod 42 starts to extend, and the first spring 43 extends and returns to its original position, so that the corresponding first scraping knife 30, second scraping knife 31, third scraping knife 32, and fourth scraping knife 33 are in contact with the inner wall of the spiral channel 19. Then the first motor 52 stops by itself, and the electromagnet 50 starts to adsorb the sliding block 49 under the action of the control terminal 12, so that the sliding block 49 moves towards the electromagnet 50 on the slideway 48, so that the clamping roller 47 clamps the control rope 27. Then the control terminal 12 will drive the first motor 52 and the third motor 54 to start. After the third motor 54 starts, its motor shaft will drive the third reel 53 to rotate, so that through the rotation of the third reel 53, the winding of the connecting rope 26 will be completed, and thus drive the slider 28 to move towards the separation space 22.Under the action of the first scraping knife 30, the second scraping knife 31, the third scraping knife 32, and the fourth scraping knife 33, the droplets inside the spiral channel 19 are scraped off. When the first motor 52 is started, the control rope 27 will be payed out. As the slider 28 moves, the control rope 27 will be pulled out, so as to keep the telescopic scraping mechanism 61 extended. When the slider 28 moves to the lowest end of the spiral slide rail 20, the control terminal 12 will drive the electromagnet 50 to reset the sliding block 49, and then start the first motor 52 and the second motor 51, so as to complete the winding of the control rope 27, and make the telescopic scraping mechanism 61 return to the initial state. The slider 28 is reset under the action of the second motor 51, which is convenient for the next drive. In this way, the scraping of the droplets in the spiral channel 19 is completed. The fourth motor 60 will also be started regularly under the action of the control terminal 12. After the fourth motor 60 is started, its motor shaft will drive the fourth reel 59 to rotate, so as to drive the traction rope 58 to tighten, and then drive the rotating plate 56 to rotate through the traction rope 58, and the second torsion spring 57 is tightened. When the fourth motor 60 stops, the rotating plate 56 is reset under the action of the second torsion spring 57. The rotation of the rotating plate 56 drives the scraping plate 25 to rotate, so as to scrape off the droplets in the separation space 22 through the scraping plate 25. The scraped-off droplets will fall into the drain port 15 through the liquid separation plate 23, so as to improve the steam-water separation effect and efficiency of the steam-water separation device.
