Description

Technical Field

[0001] The 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 that generates steam. To ensure the quality of the generated steam, a steam-water separator is usually added 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 on the top or side of the steam generator and uses a variety of physical mechanisms to achieve steam-water separation. This type of steam generator is widely used in many industries, including but not limited to: food processing, pharmaceuticals, textile printing and dyeing, chemicals, papermaking, and medical treatment.

[0003] When the existing steam-water separator separates the mixture of steam and water, it first allows the mixture of steam and water to flow through the 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 to 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 in the steam-water separator accumulates more and more, 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 will fly up, which will cause the steam to carry the water droplets out of the steam-water separator again, so that the existing steam-water separator cannot completely separate steam and water. Summary of the invention

[0004] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a steam generator with a steam-water separation structure.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A steam generator with a steam-water separation structure, such as Figure 1-Figure 4 As shown, 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 connected to a separation shell 2, the lower side of the separation shell 2 is provided with a sewage outlet, the upper side of the separation shell 2 is connected to an air outlet shell 3, and a spiral plate 4 is provided between the air outlet shell 3 and the separation shell 2; a fixed shell 5, fixedly connected to the air outlet shell 3, the fixed shell 5 is rotatably connected to a rotating member 6, and the rotating member 6 is fixedly connected to a rotating shaft 7; there are a plurality of blades 8, all of which are fixedly connected to the rotating shaft 7. The blades 8 are staggered, and the gaps between the blades 8 cover each other. The air outlet shell 3 is provided with a drainage groove 301 for isolating the separated water from the airflow, and the air outlet shell 3 is provided with a drainage outlet connected to the drainage groove 301.

[0022] In the above scheme, the purpose is to improve the separation effect of the device on the mixture of steam and water. 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 drain port on the separation shell 2 is used to discharge the water and impurities collected therein. The diameter of the upper half of the outlet shell 3 is smaller than the diameter of the lower half. The spiral plate 4 is used to change the flow direction of the steam, so that the steam rotates and flows downward, thereby generating centrifugal force to separate the water droplets therefrom. The impeller 8 is located at the larger diameter part of the outlet shell 3, and the inner diameter of the lower side of the outlet shell 3 is equal to the inner diameter of the upper side thereof, so that when the steam flows upward, it will not blow to the inner side of the larger diameter part of the outlet shell 3 to prevent the separated water droplets from re-entering the steam.

[0023] Working process: When the device is used, the steam boiler 1 generates steam and enters the separation shell 2 from the air outlet. After the steam enters the separation shell 2, it is guided by the spiral plate 4, and the steam flows in a spiral shape. When flowing, centrifugal force is generated to separate the water droplets. Then, the steam enters from the lower side of the air outlet shell 3 and is discharged from the upper side. In the process of the steam passing through the air outlet shell 3, the steam blows the impeller 8 to rotate, and the impeller 8 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the rotating part 6 to rotate. The water droplets remaining in the steam flow upward with the steam and hit the impeller 8, and then rotate with the impeller 8, and are thrown on the inner wall of the air outlet shell 3 under the action of centrifugal force, and then flow downward to the drain groove 301, and then enter the separation shell 2 from the drain port. When the water and impurities in the separation shell 2 accumulate to a certain extent, they are discharged from the sewage outlet of the separation shell 2.

[0024] Further, such as Figure 2 and Figure 3 As shown, it also includes: a sealing member 9, which is arranged between the steam boiler 1 and the separation shell 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 the cavity, and the sealing member 9 is elastic, so that the sealing member 9 can adapt to different pressures.

[0025] Further, such as Figure 5 As shown, it also includes: a sliding member 10, a rotating member 6 is provided with a first slide groove 601 and a second slide groove 602, the sliding member 10 is slidably connected to the first slide groove 601, and passes through the first slide groove 601 and the second slide groove 602, the fixed shell 5 is provided with a connecting groove 501, the connecting groove 501 is connected with the first slide groove 601, and the connecting groove 501 is connected with the sealing member 9.

[0026] In the above scheme, the seal 9 is adjusted according to the pressure in the separation shell 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 round rod. The first slide groove 601 is filled with liquid. When the sliding member 10 moves downward, the liquid in the first slide groove 601 is pressed into the connecting groove 501, and then enters the seal 9 from the connecting groove 501, thereby increasing the pressure inside the seal 9, and then increasing the pressure between the seal 9 and the separation shell 2 and the steam boiler 1, so as to increase the sealing performance between the separation shell 2 and the steam boiler 1.

[0027] Further, such as Figure 5 As shown, it also includes: a sliding block 11, which is slidably connected to the second sliding groove 602, the sliding block 11 is fixed to the sliding member 10, and a first spring is arranged between the sliding block 11 and the rotating member 6; a plurality of centrifugal blocks 12 are evenly distributed and are all slidably connected to the rotating member 6, a thin rope is arranged between the centrifugal block 12 and the sliding block 11, and the thin rope passes through the rotating member 6.

[0028] In the above scheme, the position of the sliding member 10 is adjusted according to the air pressure in the separation housing 2. The centrifugal block 12 is made of a material with a high density to provide a greater centrifugal force, and a lubricating material can be provided between the centrifugal block 12 and the rotating member 6 to reduce the friction between the two.

[0029] Working process: 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 thin rope adjacent to it, the sliding block 11 compresses the first spring adjacent to it, and pulls the sliding member 10 downward, the sliding member 10 presses the liquid in the first slide groove 601 into the connecting groove 501, and then enters the sealing member 9 from the connecting groove 501, so that the sealing member 9 and the separation shell 2 and the steam boiler 1 are squeezed against each other, so as to realize the sealing between the separation shell 2 and the steam boiler 1. When the pressure in the separation shell 2 increases, the rotation speed of the rotating member 6 increases, and the centrifugal force on the centrifugal block 12 increases, thereby transmitting the seal. The extrusion pressure between the member 9 and the separation shell 2 and the steam boiler 1 increases to ensure the sealing between the separation shell 2 and the steam boiler 1. When the pressure in the separation shell 2 decreases, the rotation speed of the rotating member 6 decreases, and the centrifugal force on 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 draws part of the liquid in the sealing member 9 into the first sliding groove 601 through the connecting groove 501, thereby reducing the extrusion pressure between the transmission sealing member 9 and the separation shell 2 and the steam boiler 1, so as to extend the service life of the sealing member 9 while meeting the sealing requirements.

[0030] Further, such as Figure 1-Figure 3As shown, it also includes: a water outlet shell 13, which is fixed to the lower side of the separation shell 2 and penetrates through it, and the water outlet shell 13 is provided with a water inlet and a water outlet.

[0031] Further, such as Figure 2 and Figure 3 As shown, it also includes: a blocking member 14 slidably connected to the water outlet shell 13 , the blocking member 14 is used to block the water inlet of the water outlet shell 13 , and a tension spring is arranged between the blocking member 14 and the separation shell 2 ; a hollow shell 15 fixedly connected to the blocking member 14 .

[0032] In the above scheme, the purpose is to realize the automatic discharge of water in the separation shell 2. The water inlet of the water outlet shell 13 is slightly higher than the lower side of the separation shell 2, so that the blocking member 14 can completely block the water inlet of the water outlet shell 13 to prevent air leakage at the water inlet of the water outlet shell 13. The lower side of the water outlet shell 13 is the water outlet, and the blocking member 14 is sleeved on the outer side of the water outlet shell 13. The hollow shell 15 is used to provide buoyancy. When the water level rises, the hollow shell 15 is subject to buoyancy. As the height of the hollow shell 15 submerged by water increases, the buoyancy of the hollow shell 15 increases.

[0033] Further, such as Figure 3 As shown, it also includes: a limiting column 16, which is slidably connected to the blocking member 14, a second spring is arranged between the blocking member 14 and the limiting column 16, and the water outlet housing 13 is provided with a groove.

[0034] In the above solution, the blocking member 14 is intended to be limited. The limiting column 16 is composed of a cylinder and a hemisphere, and the second spring between the blocking member 14 and the limiting column 16 is initially in a compressed state to increase the resistance of the blocking member 14.

[0035] Working process: When the device is used, the water in the separation shell 2 gradually increases. When the water contacts the hollow shell 15, the hollow shell 15 is subjected to buoyancy. As the height of the hollow shell 15 being submerged increases, the buoyancy exerted on the hollow shell 15 increases. When the hollow shell 15 is about to be submerged, the buoyancy exerted on the hollow shell 15 is sufficient to drive the blocking member 14 to move upward. At this time, the blocking member 14 drives the limiting column 16 to move upward. The limiting column 16 moves to the right and compresses it and the adjacent second spring. When the limiting column 16 is separated from the groove on the water outlet shell 13, the blocking member 14 loses the resistance of the limiting column 16 and moves upward quickly and stretches the adjacent tension spring until it is blocked by the upper side of the water outlet shell 13. At this time, the blocking member 14 releases the blockage of the water inlet of the water outlet shell 13. The water in the separation shell 2 enters the water inlet of the water outlet shell 13 and is then discharged from the water outlet of the water outlet shell 13. At this time, the water level in the separation shell 2 drops, but a part of the hollow shell 15 is still located in the water, so the hollow shell 15 is still subject to the buoyancy of the water. However, at this time, the buoyancy of the hollow shell 15 is greater than the tension of the tension spring adjacent to the blocking member 14, so the blocking member 14 will not move temporarily. When the water level drops to a certain level, so that the buoyancy of the hollow shell 15 is less than the tension of the tension spring adjacent to the blocking member 14, the blocking member 14 is gradually reset under the action of the adjacent tension spring, and the water inlet of the water outlet shell 13 is re-blocked to prevent steam leakage. After the resetting of the blocking member 14 is completed, the limit column 16 is reset under the action of the adjacent second spring, and the blocking member 14 is re-limited.

[0036] The present invention provides a thought and method. There are many methods and ways to implement the technical solution. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
