Description

Technical Field

[0001] This application relates to the field of papermaking equipment technology, specifically to a steam-water separator flow guiding mechanism. Background Technology

[0002] A steam-water separator is a device used to separate gas and liquid components in a liquid. Its main function is to separate the gas from the liquid in a liquid containing gas (such as steam). It is especially useful in paper steam processing, where condensation occurs during transportation due to heat radiation loss from pipelines. Therefore, it is necessary to maintain the water content of the steam, which is where the steam-water separator comes in.

[0003] During the transportation of water-containing steam in pipelines, a steam-water separator is installed to force water out, thereby increasing the dryness of the steam. The baffle in the steam-water separator changes the direction of steam flow through mechanical barriers, allowing condensate to be separated by the difference in specific gravity. A drain outlet for draining water is usually set at the bottom. Due to the uncertainty of steam flow, a water remover needs to be added in the steam-water separator to drain water and prevent steam from escaping. To address this, a flow guiding mechanism for the steam-water separator is proposed to guide and drain water-containing steam within the steam-water separator. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a steam-water separator flow guiding mechanism, which has the advantages of preventing steam from being discharged from the drain outlet, guiding water flow, and guiding steam.

[0005] To achieve the above objectives, this application provides the following technical solution: a steam-water separator guide mechanism, including a separator, with conveying pipes connected to both the left and right ends of the separator, baffles fixedly installed alternately on the inner wall of the separator, and a guide structure for draining water provided at the inclined end of the bottom wall of the separator;

[0006] The flow guiding structure includes a water storage tank formed on the bottom wall of the separation tank and a drain hole connecting the water storage tank and the outside of the separation tank. A float ball is also placed above the water storage tank.

[0007] The baffle is connected to one end of the separator and has a rectangular opening. An opening and closing plate is rotatably installed in the opening via a bearing. A guide rod is fixedly installed on the surface of the baffle on the side away from the drain hole.

[0008] Furthermore, the longitudinal section of the separation tank is trapezoidal, and the bottom wall of the separation tank is inclined to one side.

[0009] Furthermore, an installation base is fixedly installed on the inner bottom wall of the separation tank, and an arc-shaped frame is integrally connected to the installation base. The width of the arc-shaped frame corresponds to the diameter of the float.

[0010] Furthermore, the top of the water storage tank is provided with an arc-shaped groove, which is arc-shaped and corresponds to the float.

[0011] Furthermore, one end of the drain hole is located on the arc-shaped groove, and a sealing ring is fixedly installed at the end of the drain hole.

[0012] Furthermore, a counterweight is fixedly installed on the side of the opening and closing plate facing the drain hole.

[0013] Furthermore, a rubber strip is fixedly installed on the side of the top of the opening plate that contacts the upper end of the opening, and the upper end of the rubber strip is arc-shaped.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This steam-water separator guide mechanism separates water from steam by setting up a mechanical baffle structure inside the separator. A water storage tank is opened on one side of the separator and sealed with a float ball. Under normal conditions, the drain hole can be closed by the float ball. When water is stored, the drain hole is closed by the liquid level. This ensures that the separator drains water while closing the drain hole, preventing steam from being discharged from the drain hole. Furthermore, the installation of an opening and closing plate on the baffle to guide and collect water improves the practicality of the device. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1 to 3The steam-water separator guide mechanism in this embodiment includes a separator 1. Both the left and right ends of the separator 1 are connected to a conveying pipe 2 for feeding steam in and feeding steam out. The longitudinal section of the separator 1 is trapezoidal, and the bottom wall of the separator 1 is inclined to one side to guide the water flowing on the inner wall of the separator 1.

[0022] In this embodiment, baffles 3 are fixedly installed on the inner wall of the separator 1 in an alternating manner to block and change the direction of steam flow, so that the water contained in the steam remains on the surface of the baffles 3 under the action of specific gravity for separation.

[0023] It should be noted that the inclined end of the bottom wall of the separator 1 is provided with a flow guiding structure for draining water. The flow guiding structure includes a water storage tank 7 opened on the bottom wall of the separator 1 and a drain hole 4 connecting the water storage tank 7 and the outside of the separator 1.

[0024] The water inside the separator 1 flows along its bottom wall and gathers in the water storage tank 7, and can then be discharged out of the separator 1 through the drain hole 4.

[0025] In this embodiment, an installation base 5 is also fixedly installed on the inner bottom wall of the separation tank 1. An arc-shaped frame 6 is integrally connected to the installation base 5. A float 9 is placed above the water storage tank 7. The width of the arc-shaped frame 6 corresponds to the diameter of the float 9, and the upward position of the float 9 can be restricted by the arc-shaped frame 6.

[0026] In this embodiment, the top of the water storage tank 7 is provided with an arc-shaped groove 8, which is arc-shaped and corresponds to the float 9.

[0027] This design allows the arc-shaped groove 8 and the float 9 to come into contact with each other, thereby improving the sealing effect of the float 9.

[0028] It should be noted that one end of the drain hole 4 is located on the arc groove 8, and a sealing ring 10 is fixedly installed at the end of the drain hole 4.

[0029] By having the sealing ring 10 and the float 9 in contact with each other, the sealing effect of the float 9 on the drain hole 4 can be further improved, so that the drain hole 4 can be sealed during normal steam supply.

[0030] In order to allow the water on the bottom wall of the separator 1 to pass over the baffle 3, in this embodiment, the baffle 3 is connected to one end of the separator 1 and has a rectangular opening 12. An opening and closing plate 13 is rotatably installed in the opening 12 through a bearing. The opening and closing plate 13 can be rotated open relative to the opening 12 so that the water can accumulate and pass over the baffle 3.

[0031] Preferably, a counterweight 14 is fixedly installed on the side of the opening and closing plate 13 facing the drain hole 4. The counterweight 14 enables the opening and closing plate 13 to close naturally at the opening 12.

[0032] In this embodiment, a rubber strip 15 is fixedly installed on the side of the top of the opening plate 13 that contacts the upper end of the opening 12. The upper end of the rubber strip 15 is arc-shaped. By setting the rubber strip 15, the sealing effect after the opening plate 13 rotates and closes can be improved, and the upper end of the opening plate 13, which moves in an arc trajectory, can be flipped open by squeezing the rubber strip 15 toward the opening 12.

[0033] It should be noted that a guide rod 11 is fixedly installed on the surface of the baffle 3 on the side away from the drain hole 4. The guide rod 11 extends toward the opening 12 and is used to guide the water on the surface of the baffle 3.

[0034] The working principle of the above embodiments is as follows:

[0035] Steam containing water vapor is introduced into the interior of the separator tank 1 through the conveying pipe 2 on one side. As the steam flows along the gap between the baffles 3, it is driven by the steam flow rate to separate the water in the steam onto the baffles 3 and the bottom wall of the separator tank 1 by the difference in specific gravity. At this time, the steam is sent out through the conveying pipe 2 on the other side to complete the separation of water. The separated water is guided by the guide rod 11 on the surface of the baffle 3 and gathers between the baffle 3 and the bottom wall of the separator tank 1. After a certain amount of water has gathered, the gravity of the water pushes the opening and closing plate 13 to flip relative to the baffle 3 to create a gap for water to flow through, until the water passes through all the baffles 3 and gathers in the water storage tank 7 on one side. The water level rises and forces the float ball 9 on the water storage tank 7 to float. At this time, after the float ball 9 is removed from the position of the drain hole 4, the water is discharged through the drain hole 4. During the drainage process, the drain hole 4 is sealed by the liquid level so that the steam will not be discharged through the drain hole 4.
