Description
Technical Field
[0001] The present invention belongs to the technical field of steam generators, and mainly proposes a steam generator with a steam-water separation structure. Background Art
[0002] A steam generator is a device for generating steam. To ensure the quality of the generated steam, a steam-water separator is usually attached inside it to effectively remove the moisture in the steam and ensure that the output is dry saturated steam. This type of steam generator is particularly important in industrial applications because it can significantly improve production efficiency and product quality, while reducing equipment wear and energy consumption. The steam-water separator is usually located at the top or side of the steam generator and uses various physical mechanisms to achieve steam-water separation. This type of steam generator is widely used in multiple industries, including but not limited to: food processing, pharmaceuticals, textile printing and dyeing, chemical industry, papermaking, and healthcare.
[0003] When the existing steam-water separator separates the mixture of steam and water, first, the mixture of steam and water flows through a rotating component. Since the mass of water droplets is greater than that of steam molecules, under the action of centrifugal force, the water droplets are thrown towards the container wall and enter the lower side of the steam-water separator through the drain port, while the steam flows upward and is discharged. As the water accumulates more and more in the steam-water separator, the water surface will approach the exhaust port of the steam-water separator. At this time, the water collected on the lower side of the steam-water separator will be blown by the steam, causing ripples on its surface and even water droplets to fly up. This will cause the steam to re-carry water droplets and be discharged from the steam-water separator, so that the existing steam-water separator cannot separate steam and water thoroughly. Summary of the Invention

Detailed Description of the Invention
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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 of 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.
[0025] A steam generator with a steam-water separation structure, as Figures 1-4As shown in the figure, it includes: a steam boiler 1, the steam boiler 1 is provided with an air outlet, the air outlet of the steam boiler 1 is communicated with a separation housing 2, the lower side of the separation housing 2 is provided with a blowdown port, the upper side of the separation housing 2 is communicated with an air outlet housing 3, and a spiral plate 4 is arranged between the air outlet housing 3 and the separation housing 2; a fixed housing 5, fixedly connected inside the air outlet housing 3, the fixed housing 5 is rotationally connected with a rotating member 6, and the rotating member 6 is fixedly connected with a rotating shaft 7; a plurality of fan blades 8, all fixedly connected to the rotating shaft 7. The plurality of fan blades 8 are staggered, and the gaps between the plurality of fan blades 8 are mutually blocked. The air outlet housing 3 is provided with a drainage groove 301 for isolating the separated water from the air flow, and the air outlet housing 3 is provided with a drainage port communicated with the drainage groove 301.
[0026] In the above solution, it aims to improve the separation effect of the mixture of steam and water of the device. The steam boiler 1 is provided with a pressure gauge and a pressure relief valve. The pressure gauge is used to monitor the air pressure in the steam boiler 1, and the pressure relief valve is used to prevent the air pressure in the steam boiler 1 from being too high. The blowdown port on the separation housing 2 is used to discharge the water and impurities collected therein. The upper half part of the air outlet housing 3 has a smaller diameter than the lower half part. The spiral plate 4 is used to change the flow direction of the steam, so that the steam rotates and flows downward, thereby generating a centrifugal force to separate the water droplets therefrom. The fan blades 8 are located in the part of the air outlet housing 3 with a larger diameter. The inner diameter of the lower side of the air outlet housing 3 is equal to the inner diameter of its upper side, so that when the steam flows upward, it will not blow to the inner side of the part of the air outlet housing 3 with a larger diameter, so as to prevent the separated water droplets from entering the steam again.
[0027] Working process: When using this device, the steam boiler 1 generates steam and enters the separation housing 2 from the air outlet. After the steam enters the separation housing 2, it is guided by the spiral plate 4, and the steam flows in a spiral shape, generating a centrifugal force to separate the water droplets during the flow. Then the steam enters from the lower side of the air outlet housing 3 and is discharged from the upper side. During the process of the steam passing through the air outlet housing 3, the steam blows the fan blades 8 to rotate. The fan blades 8 drive the rotating shaft 7 to rotate, and the rotating shaft 7 drives the rotating member 6 to rotate. The remaining water droplets in the steam flow upward with the steam and impact on the fan blades 8, and then rotate with the fan blades 8 and are thrown on the inner wall of the air outlet housing 3 under the action of the centrifugal force, and then flow downward into the drainage groove 301, and then enter the separation housing 2 from the drainage port. When the water and impurities in the separation housing 2 accumulate to a certain extent, they are discharged from the blowdown port of the separation housing 2.
[0028] Furthermore, as Figure 2 and Figure 3 shown, it further includes: a sealing member 9, arranged between the steam boiler 1 and the separation housing 2, and the sealing member 9 is provided with a cavity. The wall thickness of the sealing member 9 is greater than the diameter of the longitudinal section of its cavity. The sealing member 9 has elasticity and is used to make the sealing member 9 adapt to different pressures.
[0029] Furthermore, as Figure 5As shown in the figure, it further includes: a sliding member 10. The rotating member 6 is provided with a first sliding groove 601 and a second sliding groove 602. The sliding member 10 is slidably connected to the first sliding groove 601 and penetrates between the first sliding groove 601 and the second sliding groove 602. The fixed housing 5 is provided with a communication groove 501. The communication groove 501 is communicated with the first sliding groove 601, and the communication groove 501 is communicated with the seal 9.
[0030] In the above solution, it is intended to adjust the seal 9 according to the pressures in the separation housing 2 and the steam boiler 1 to ensure the sealing performance of the seal 9 and extend its service life. The sliding member 10 is composed of a circular plate and a circular rod. The first sliding groove 601 is filled with liquid. When the sliding member 10 moves downward, the liquid in the first sliding groove 601 is pressed into the communication groove 501 and then enters the seal 9 from the communication groove 501, thereby increasing the pressure inside the seal 9, and further increasing the pressure between the seal 9 and the separation housing 2 and the steam boiler 1 to enhance the sealing performance between the separation housing 2 and the steam boiler 1.
[0031] Furthermore, as Figure 5 shown in the figure, it further includes: a sliding block 11, which is slidably connected to the second sliding groove 602. The sliding block 11 is fixedly connected to the sliding member 10. A first spring is provided between the sliding block 11 and the rotating member 6; a plurality of centrifugal blocks 12, which are evenly distributed, are all slidably connected to the rotating member 6. A thin string is provided between the centrifugal blocks 12 and the sliding block 11, and the thin string passes through the rotating member 6.
[0032] In the above solution, it is intended to adjust the position of the sliding member 10 according to the air pressure in the separation housing 2. The centrifugal blocks 12 are made of materials with high density to provide greater centrifugal force. Lubricating materials can be provided between the centrifugal blocks 12 and the rotating member 6 to reduce the friction between the two.
[0033] Workflow: When the rotating member 6 rotates, the rotating member 6 drives the centrifugal block 12 to rotate. The centrifugal block 12 moves under the action of centrifugal force and pulls the sliding block 11 downward through the adjacent thin rope. The sliding block 11 compresses the adjacent first spring and pulls the sliding member 10 downward. The sliding member 10 presses the liquid in the first chute 601 into the communication groove 501, and then enters the seal 9 from the communication groove 501, so that the seal 9 is mutually extruded with the separation housing 2 and the steam boiler 1, realizing the seal between the separation housing 2 and the steam boiler 1. When the pressure in the separation housing 2 increases, the rotation speed of the rotating member 6 increases, and the centrifugal force received by the centrifugal block 12 increases, so that the extrusion force between the transmission seal 9 and the separation housing 2 and the steam boiler 1 increases, ensuring the seal between the separation housing 2 and the steam boiler 1. When the pressure in the separation housing 2 decreases, the rotation speed of the rotating member 6 decreases, the centrifugal force received by the centrifugal block 12 decreases, the sliding block 11 moves upward under the action of the adjacent first spring, and pulls the centrifugal block 12 to move through the thin rope. At the same time, the sliding block 11 drives the sliding member 10 to move upward. The sliding member 10 pumps part of the liquid in the seal 9 into the first chute 601 through the communication groove 501, thereby reducing the extrusion force between the transmission seal 9 and the separation housing 2 and the steam boiler 1, so as to extend the service life of the seal 9 while meeting the sealing requirements.
[0034] Furthermore, as Figures 1-3 shown, it further includes: a water outlet housing 13, fixedly connected to the lower side of the separation housing 2 and penetrating it. The water outlet housing 13 is provided with a water inlet and a water outlet.
[0035] Furthermore, as Figure 2 and Figure 3 shown, it further includes: a plugging member 14, slidably connected to the water outlet housing 13. The plugging member 14 is used to plug the water inlet of the water outlet housing 13. A tension spring is arranged between the plugging member 14 and the separation housing 2; a hollow housing 15, fixedly connected to the plugging member 14.
[0036] In the above solution, it aims to realize the automatic discharge of water in the separation housing 2. The water inlet of the water outlet housing 13 is slightly higher than the lower side of the separation housing 2, so that the plugging member 14 can completely plug the water inlet of the water outlet housing 13 to avoid air leakage at the water inlet of the water outlet housing 13. The lower side of the water outlet housing 13 is the water outlet. The plugging member 14 is sleeved on the outer side of the water outlet housing 13. The hollow housing 15 is used to provide buoyancy. When the water level rises, the hollow housing 15 receives buoyancy. As the height of the hollow housing 15 submerged in water increases, the buoyancy received by the hollow housing 15 increases.
[0037] Furthermore, as Figure 3 shown, it further includes: a limit post 16, slidably connected to the plugging member 14. A second spring is arranged between the plugging member 14 and the limit post 16. The water outlet housing 13 is provided with a groove.
[0038] In the above solution, it is intended to limit the plugging member 14. The limiting post 16 is composed of a cylinder and a hemisphere. The second spring between the plugging member 14 and the limiting post 16 is initially in a compressed state to increase the resistance received by the plugging member 14.
[0039] Working process: When this device is in use, the water in the separation housing 2 gradually increases. When the water contacts the hollow shell 15, the hollow shell 15 receives buoyancy. As the submerged height of the hollow shell 15 increases, the buoyancy received by the hollow shell 15 increases. When the hollow shell 15 is about to be submerged, the buoyancy received by the hollow shell 15 is sufficient to drive the plugging member 14 to move upward. At this time, the plugging member 14 drives the limiting post 16 to move upward, and the limiting post 16 moves to the right and compresses the second spring adjacent to it. When the limiting post 16 separates from the groove on the water outlet housing 13, the plugging member 14 loses the resistance of the limiting post 16 and quickly moves upward and stretches the adjacent tension spring until it is blocked by the upper side of the water outlet housing 13. At this time, the plugging member 14 releases the plugging of the water inlet of the water outlet housing 13, and the water in the separation housing 2 enters the water inlet of the water outlet housing 13 and then is discharged from the water outlet of the water outlet housing 13. At this time, the water level in the separation housing 2 drops, but part of the hollow shell 15 is still in the water, so the hollow shell 15 still receives the buoyancy of the water. However, at this time, the buoyancy received by the hollow shell 15 is greater than the tension of the tension spring adjacent to the plugging member 14, so the plugging member 14 will not move temporarily. When the water level drops to a certain extent such that the buoyancy received by the hollow shell 15 is less than the tension of the tension spring adjacent to the plugging member 14, the plugging member 14 gradually resets under the action of the adjacent tension spring and re-plugs the water inlet of the water outlet housing 13 to prevent steam leakage. After the plugging member 14 finishes resetting, the limiting post 16 resets under the action of the adjacent second spring and re-limits the plugging member 14.
[0040] The present invention provides an idea and method. There are many ways and means to specifically implement this technical solution. The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be realized by the prior art.
