Description

Technical Field

[0001] This utility model belongs to the technical field of boiler equipment, and specifically relates to a steam-water separation device. Background Technology

[0002] Steam-water separators are widely used in various chemical and energy industries. They are mainly used to separate moisture from steam to prevent moisture from entering gas pipelines along with the steam.

[0003] Existing steam-water separation devices generally only use the principle of gravity to separate gas and water, resulting in a mediocre separation effect. Furthermore, the short circulation path of steam within the steam-water separation device further affects the separation effect. Utility Model Content

[0004] This invention provides a steam-water separation device to solve the technical problem of poor steam-water separation effect in existing steam-water separation devices.

[0005] This utility model includes: a shell;

[0006] The mixture inlet is located above one side of the housing;

[0007] The gas outlet is located above the other side of the housing;

[0008] The liquid outlet is located at the bottom of the housing;

[0009] A partition is disposed inside the housing, dividing the housing into a first chamber and a second chamber. The first chamber corresponds to the mixture inlet and the liquid outlet, and the second chamber corresponds to the gas outlet. The lower part of the partition is a perforated plate.

[0010] This invention divides the shell into two chambers by a partition, allowing the water vapor mixture to flow from top to bottom and the gas to flow from bottom to top, thus achieving water vapor separation.

[0011] Furthermore: the structure of the partition is an inclined plate or a Z-shaped plate. The beneficial effect of this step is that the partition increases the flow resistance of the water vapor mixture, reduces its flow velocity, and allows it to accumulate in the first chamber, allowing more small water droplets to converge into large water droplets, which then flow downwards to the liquid outlet under the action of gravity.

[0012] Furthermore: when the partition is a Z-shaped plate, the partition includes a top partition, a vertical partition, and a bottom partition, and the bottom partition is a perforated plate. The beneficial effect of this step is that it allows gas to pass through the perforations on the bottom partition.

[0013] Furthermore, the first chamber is equipped with corrugated plate packing. The beneficial effect of this step is that the corrugated plate packing extends the flow path of the water vapor mixture and improves the water vapor separation effect.

[0014] Furthermore, the surface of the corrugated plate filler is provided with a hydrophilic coating. The beneficial effect of this step is that the hydrophilic coating can adhere to more droplets.

[0015] Furthermore, the second chamber is equipped with water-absorbing packing material. The beneficial effect of this step is that the water-absorbing packing material increases the adsorption of water vapor in the gas.

[0016] Furthermore: the bottom partition is a double-layer structure, and the water-absorbing filler is located between the bottom partitions. The beneficial effect of this step is that the double-layer bottom partition constrains the water-absorbing filler, preventing it from being carried out by the gas.

[0017] Furthermore, a safety valve interface is also provided at the top of the second chamber. The beneficial effect of this step is that a safety valve is connected through the safety valve interface to prevent excessive pressure inside the second chamber.

[0018] The beneficial effects of this utility model are:

[0019] 1. This application combines the effect of gravity and extends the flow path of the water vapor mixture to enable effective separation of the water vapor mixture and prevent moisture from entering the gas pipeline with the gas.

[0020] 2. The water-absorbing packing further removes moisture from the gas, keeping the gas dry. Attached Figure Description

[0030] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] Implementation of this application, for example Figure 1 and Figure 2 As shown, this utility model provides a steam-water separation device.

[0034] This utility model includes: a shell 1;

[0035] Mixture inlet 2 is located above one side of the housing 1;

[0036] Gas outlet 3 is located above the other side of the housing 1;

[0037] Liquid outlet 4 is located at the bottom of the housing 1;

[0038] A partition 5 is disposed inside the housing 1, dividing the housing 1 into a first chamber 11 and a second chamber 12. The first chamber 11 corresponds to the mixture inlet 2 and the liquid outlet 4, and the second chamber 12 corresponds to the gas outlet 3. The lower part of the partition 5 is a perforated plate.

[0039] This invention divides the shell 1 into two chambers by using a partition 5, allowing the water vapor mixture to flow from top to bottom and the gas to flow from bottom to top, thus achieving water vapor separation.

[0040] Based on the above technical solution, the structure of the partition 5 is an inclined plate or a Z-shaped plate. The partition 5 increases the flow resistance of the water vapor mixture, reduces its flow velocity, and allows it to accumulate in the first chamber 11. This allows more small water droplets to converge into large water droplets, which then flow downwards into the liquid outlet 4 under the action of gravity. Then, the gas passes through the mesh plate and enters the second chamber 12.

[0041] Based on the above technical solution, the partition 5 is preferably a Z-shaped plate. When the partition 5 is a Z-shaped plate, the partition 5 includes a top partition 51, a vertical partition 52 and a bottom partition 53. The bottom partition 53 is a perforated plate. The Z-shaped plate structure is more stable, easier to process, and easier to weld to the shell 1, allowing gas to pass through the mesh on the bottom partition 53.

[0042] Based on the above technical solution, the first chamber 11 is provided with corrugated plate packing 6, which extends the flow path of the water vapor mixture and improves the water vapor separation effect.

[0043] In addition, the corrugated plate packing 6 can be replaced with a corrugated plate heat exchanger, which has a refrigerant flow channel and a water vapor mixture flow channel. The inlet and outlet of the refrigerant flow channel both pass through the shell 1 and are connected to the external refrigerant. When the water vapor mixture enters the corrugated plate heat exchanger, it will be cooled by the refrigerant, causing the water to condense into a liquid state, improving the dehumidification effect and accelerating the separation of water vapor.

[0044] Based on the above technical solution, the surface of the corrugated plate filler 6 is provided with a hydrophilic coating. The hydrophilic coating can adhere to more droplets, which gather at the bottom of the shell 1 and are discharged through the liquid outlet 4.

[0045] Based on the above technical solution, the second chamber 12 is provided with water-absorbing filler 7. The water-absorbing filler 7 is generally made of resin, ceramic and gel, etc. The water-absorbing filler 7 increases the adsorption of water vapor in the gas. When the water absorption effect of the water-absorbing filler 7 becomes poor, the water-absorbing filler 7 can be heated by passing in high temperature gas to remove the internal moisture and reuse it.

[0046] Based on the above technical solution, the bottom partition 53 has a double-layer structure, and the water-absorbing filler 7 is located between the bottom partitions 53. The double-layer bottom partitions 53 constrain the water-absorbing filler 7 and prevent the water-absorbing filler 7 from being carried out by the gas.

[0047] Based on the above technical solution, the top of the second chamber 12 is also provided with a safety valve interface 8, through which a safety valve is connected to avoid excessive pressure inside the second chamber 12 and potential safety hazards. In addition, the safety valve interface 8 can also be used as an inlet for the high-temperature gas mentioned above.

[0048] In the above embodiments, the perforated plate mentioned in this application typically has a mesh diameter of 2-4 mm, a row spacing and column spacing of 6-10 mm, and the meshes in adjacent rows are staggered. The mesh isolates moisture and gas, achieving the effect of water vapor separation.

[0049] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
