Description
Technical Field
[0001] The utility model relates to a gas-liquid separation device for high-temperature steam and a steam processing system. Background Art
[0002] When factories that use steam for production discharge high-temperature condensed water and steam, they need to cool down the high-temperature steam condensate gas to prevent the high-temperature gas flowing out of the discharge port from scalding pedestrians. Factories usually use heat exchangers to exchange heat with steam, or use refrigeration equipment to cool the steam, thereby achieving cold discharge of steam. The above cooling methods often take up more space or consume more energy, so it is necessary to provide a gas-liquid separation device and steam treatment system for high-temperature steam. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defects in the prior art and provide a gas-liquid separation device and a steam processing system for high-temperature steam.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] The utility model provides a gas-liquid separation device for high-temperature steam, the gas-liquid separation device comprises a first pipeline and a second pipeline, one end of the first pipeline is used to be connected to an external steam source, and the other end of the first pipeline is provided with a liquid sealing structure;
[0006] The second pipeline is connected to the first pipeline and the connecting point is close to the liquid sealing structure;
[0007] A third pipe is provided above the second pipe, the inner diameter of the third pipe is at least 5 times the inner diameter of the second pipe, the second end of the second pipe extends into the third pipe, and the distance between one end of the third pipe away from the second pipe and the end of the second pipe extending into the third pipe is 120 mm to 300 mm.
[0008] In this solution, the above structure is adopted, the first pipe is used for preliminary condensation of steam, the liquid seal structure separates the condensed water from the steam, and the separated steam passes through the second pipe and enters the third pipe for dissipation and condensation. By limiting the inner diameter ratio of the third pipe to the second pipe, the steam can be fully dissipated and cooled after entering the third pipe to meet the temperature emission standard. The gas-liquid separation device for high-temperature steam in this solution allows high temperature to be cooled and condensed without the interference of external equipment, without the need to consume additional equipment and energy, which not only reduces energy consumption but also saves costs.
[0009] Preferably, the liquid sealing structure is a curved pipe, one end of which is connected to the first pipeline, and the other end of which is provided with an opening.
[0010] In this solution, the condensed water in the first pipe flows into the elbow and out from one end of the elbow, thereby preventing the condensed water from accumulating in the first pipe. The steam flowing into the elbow is blocked by the condensed water accumulated in the elbow. The steam is blocked in the first pipe by the elbow, thereby allowing the steam to overflow along the second pipe for further dissipation, condensation and cooling.
[0011] Preferably, the bent pipe has a U-shaped water storage structure, the opening is arranged upward, and the plane where the opening is located is not higher than the first pipe.
[0012] In this solution, the above structure is adopted, which, on the one hand, allows sufficient water to be contained in the elbow to prevent steam from flowing out of the elbow, and on the other hand, facilitates the rapid discharge of condensed water generated by steam from the elbow.
[0013] Preferably, one end of the second pipe is inserted into the third pipe, and an annular air inlet is formed between the inner wall surface of the third pipe and the outer wall surface of the second pipe.
[0014] In this solution, there is steam flow force between the third pipe and the second pipe. Driven by the suction force of the upward flowing steam, cold air is introduced into the third pipe from the annular air inlet at the lower part of the third pipe, thereby realizing heat exchange between cold air and steam in the third pipe, so that the steam entering the third pipe is quickly condensed.
[0015] Preferably, the third pipeline is a straight pipe and is arranged vertically.
[0016] In this solution, the above structure is adopted, which can facilitate the condensed water to flow downward along the inner wall of the third pipe, and the condensed water part of the upper part of the third pipe flows back to the second pipe to cool the steam, so as to achieve the effect of secondary utilization of the condensed water. The third pipe is set as a straight pipe, which can also facilitate the processing and forming of the annular air inlet, so that the external air can smoothly and evenly enter the third pipe along the outer wall of the second pipe.
[0017] Preferably, the inner diameter of the first pipeline is larger than the inner diameter of the second pipeline, and the inner diameter of the first pipeline is smaller than the inner diameter of the third pipeline.
[0018] In this solution, the steam enters the second pipe from the first pipe and is compressed due to the narrowing of the passage, so that the pressure of the steam entering the second pipe increases. After entering the third pipe, the steam passage suddenly becomes larger, so that the steam pressure suddenly decreases and is released, thereby causing the steam entering the third pipe to cool down quickly. In addition, there is steam flow force between the third pipe and the second pipe, and the lower part of the third pipe is driven by the suction force of the upward flowing steam to introduce cold air, thereby achieving heat exchange between the cold air and the steam, and further causing the steam entering the third pipe to cool down and condense quickly.
[0019] The utility model also provides a steam processing system, which includes the gas-liquid separation device as described above, one end of the first pipeline is connected to an external steam source, one end of the first pipeline connected to a liquid sealing structure is arranged in a manhole, and the third pipeline is arranged above the manhole.
[0020] Preferably, the manhole is provided with a closed cover, and the second pipeline is arranged through the closed cover;
[0021] The steam treatment system further comprises a fourth pipeline, one end of which extends into the manhole, and the other end of which extends into the third pipeline.
[0022] In this scheme, due to the temperature difference between the condensed water and the water in the manhole, some water vapor may also be generated. By setting up a fourth pipe, the water vapor inside the manhole can be discharged to the outside of the manhole and further condensed from the third pipe. The temperature of the condensed water falling back from the third pipe into the manhole is reduced.
[0023] Preferably, the height of the third conduit from the closing cover is at least twice the diameter of the second conduit.
[0024] In this solution, the third pipe is suspended at a preset height, so that sufficient air can quickly enter the third pipe, thereby fully realizing the convection exchange between steam and cold air.
[0025] Preferably, the first pipeline is laid under the ground, and the distance between the first pipeline and the ground is at least 20 cm.
[0026] In this solution, the first pipeline is arranged under the ground, and the steam in the first pipeline can be cooled by heat exchange through the lower temperature of the ground, so that the steam is partially condensed in the first pipeline.
[0027] The positive and progressive effect of the utility model is that the first pipe is used to preliminarily condense the steam, and the separated steam is allowed to pass through the second pipe and then enter the third pipe for dissipation and condensation through the liquid seal structure. By limiting the inner diameter ratio of the third pipe to the second pipe, not only can the steam be fully dissipated and cooled after entering the third pipe to meet the temperature emission standard, but also the energy-free automatic flow of steam can be realized, saving working energy consumption.

[0038] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0039] like Figure 1 As shown, this embodiment provides a gas-liquid separation device for high-temperature steam, which includes a first pipe 1 and a second pipe 2, one end of the first pipe 1 is used to connect to an external steam source, and the other end of the first pipe 1 is provided with a liquid seal structure 5. The second pipe 2 is connected to the first pipe 1 and the connection is close to the liquid seal structure 5. A third pipe 3 is provided above the second pipe 2, and the inner diameter of the third pipe 3 is at least 5 times the inner diameter of the second pipe 2. The second end of the second pipe 2 extends into the third pipe 3, and the distance between the end of the third pipe 3 away from the second pipe 2 and the end of the second pipe 2 extending into the third pipe 3 is 210 mm. In other embodiments, the distance between the end of the third pipe 3 away from the second pipe 2 and the end of the second pipe 2 extending into the third pipe 3 can also be any other value between 120 mm and 300 mm.
[0040] The first pipe 1 is used for preliminary condensation of steam, and the liquid seal structure 5 separates the condensed water from the steam. The separated steam passes through the second pipe 2 and enters the third pipe 3 for release and condensation. By limiting the inner diameter ratio of the third pipe 3 to the second pipe 2, not only can the steam fully exchange heat with the cold air after entering the third pipe 3, but the steam after release and cooling can meet the temperature emission standard; the gas-liquid separation device for high-temperature steam in this embodiment allows the high temperature to be cooled and condensed without the interference of external equipment, without consuming additional equipment and energy, which not only reduces energy consumption but also saves costs.
[0041] After the steam enters the first pipe 1, it is partially condensed into condensed water, and the condensed water is separated from the steam at the liquid seal structure 5 at the end of the first pipe 1. The remaining steam flows upward from the second pipe 2 to the third pipe 3, and the condensed water flows out from the liquid seal structure 5. In this embodiment, the inner diameter of the third pipe 3 is 10 times the inner diameter of the second pipe 2, so that the steam entering the third pipe 3 can be fully released to form condensed water. In other embodiments, the inner diameter of the third pipe 3 can also be other multiples of more than 5 times the inner diameter of the second pipe 2.
[0042] The difference in inner diameters between the third pipe 3 and the second pipe 2 is relatively large, so that the steam pressure in the third pipe 3 is lower than the pressure in the second pipe 2, so that the steam in the second pipe 2 can flow out of the second pipe 2 smoothly, avoiding steam backflow due to size reduction during the flow of steam from the first pipe 1 to the second pipe 2, thereby improving the safety of gas-liquid separation of high-temperature steam.
[0043] The liquid seal structure 5 is a curved pipe, one end of which is connected to the first pipe 1, and the other end of which is provided with an opening. The condensed water in the first pipe 1 flows into the curved pipe from one end and flows out, and the steam flowing into the curved pipe is blocked by the condensed water accumulated in the curved pipe. The steam is blocked by the curved pipe in the first pipe 1 so that the steam can overflow along the second pipe 2 for further dissipation, condensation and cooling. In this embodiment, the curved pipe and the first pipe 1 are integrally formed. In other embodiments, the curved pipe and the first pipe 1 can also be a separate structure.
[0044] Specifically, the elbow has a U-shaped water storage structure with an opening facing upward and the plane where the opening is located is not higher than the first pipe 1. On the one hand, there is enough water in the elbow to prevent steam from flowing out of the elbow, and on the other hand, it is convenient for condensed water generated by steam to be quickly discharged from the elbow.
[0045] At one end of the third pipe 3 inserted with the second pipe 2, an annular air inlet is formed between the inner wall of the third pipe 3 and the outer wall of the second pipe 2. There is steam flow force between the third pipe 3 and the second pipe 2. Driven by the suction force of the upward flowing steam, the lower part of the third pipe 3 introduces cold air into the third pipe 3 from the annular air inlet, thereby achieving heat exchange between cold air and steam in the third pipe 3, so that the steam entering the third pipe 3 is quickly condensed.
[0046] In this embodiment, the third pipe 3 is a straight pipe and is arranged vertically, so that the condensed water flows downward along the inner wall of the third pipe 3, and the condensed water part of the upper part of the third pipe 3 flows back to the second pipe 2 to cool the steam, so as to achieve the effect of secondary utilization of the condensed water. The third pipe 3 is arranged as a straight pipe, which can also facilitate the processing and forming of the annular air inlet, so that the external air can smoothly and evenly enter the third pipe 3 along the outer wall of the second pipe 2. In other embodiments, the third pipe 3 can also be a curved pipe that can cooperate with the second pipe to release the steam.
[0047] The inner diameter of the first pipe 1 is larger than that of the second pipe 2, and the inner diameter of the first pipe 1 is smaller than that of the third pipe 3. When the steam enters the second pipe 2 from the first pipe 1, it is compressed due to the narrowing of the passage, which increases the pressure of the steam entering the second pipe 2. After entering the third pipe 3, the steam pressure suddenly decreases and is released due to the sudden enlargement of the steam passage, thereby rapidly cooling the steam entering the third pipe 3. There is steam flow force between the third pipe 3 and the second pipe 2. The lower part of the third pipe 3 is driven by the suction force of the upward flowing steam to introduce cold air, thereby realizing heat exchange between the cold air and the steam, and further rapidly cooling and condensing the steam entering the third pipe 3.
[0048] This embodiment provides a steam treatment system, which includes the gas-liquid separation device as described above, one end of the first pipe 1 is connected to an external steam source, one end of the first pipe 1 connected to a liquid seal structure 5 is arranged in a manhole 7, and the third pipe 3 is arranged above the manhole 7. The condensed water liquid naturally falls into the manhole after passing through the liquid seal structure 5, and is naturally cooled by the accumulated rainwater in the manhole 7. With the above structure, the gas-liquid separation device is applied in the factory and combined with the manhole 7, which can solve the hidden danger of irregular steam spraying at the end of the conventional pipe to scald people. The whole process is simple and efficient, and does not require any additional secondary energy consumption.
[0049] The manhole 7 is provided with a closing cover 6, and the second pipe 2 is arranged to pass through the closing cover 6. The second pipe 2 is fixed by the closing cover 6, so that the steam flows upward from the part of the second pipe 2 located below the closing cover 6 to the part of the second pipe 2 located above the closing cover 6, and then flows into the third pipe 3.
[0050] The steam treatment system further includes a fourth pipe 4, one end of which extends into the manhole 7, and the other end of which extends into the third pipe 3. Due to the temperature difference between the condensed water and the water in the manhole 7, some water vapor may be generated. By providing the fourth pipe 4, the water vapor inside the manhole 7 can be guided out of the manhole 7 and further condensed from the third pipe 3. The temperature of the condensed water falling from the third pipe 3 into the manhole 7 is sufficiently reduced.
[0051] The height of the third pipe 3 from the closing cover 6 is at least twice the diameter of the second pipe 2. For example, the inner diameter of the second pipe 2 is 90 mm, and the third pipe 3 is suspended for more than 180 mm, so that sufficient air can quickly enter the third pipe 3 to fully realize the convection exchange between steam and cold air. In this embodiment, the release time of the steam source is not fixed. Since the steam will not overflow from the bottom of the third pipe 3, the released steam will not scald pedestrians passing by.
[0052] The first pipe 1 is laid under the ground 8, and the distance between the first pipe 1 and the ground 8 is at least 20 cm. The first pipe 1 is arranged under the ground 8, and the steam in the first pipe 1 can be cooled by heat exchange with the lower temperature of the ground, so that the steam is condensed in the first pipe 1. The first pipe 1 is connected to the steam source in the factory, and the steam in the factory can be led out from under the ground 8 to the manhole 7 outside the factory. The distance between the first pipe 1 and the ground 8 is limited, and the steam in the first pipe 1 can be prevented from scalding the passing staff.
[0053] The utility model is not limited to the above-mentioned embodiments. Any changes in shape or structure are within the protection scope of the utility model. The protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the utility model, but these changes and modifications are within the protection scope of the utility model.
