Description

Technical Field

[0001] This utility model relates to the field of steam pipelines, and specifically to a steam pipeline exhaust structure. Background Technology

[0002] In industrial production processes, steam pipeline systems are widely used in heating, power generation, chemical industries, and other fields. When steam is transported within pipelines, condensation occurs due to temperature changes and pressure fluctuations. Additionally, non-condensable gases such as air may also be introduced into the pipeline. If this condensation and non-condensable gases are not promptly removed, it can lead to pipeline corrosion, reduced thermal efficiency, water hammer, and other problems, affecting the safe and stable operation of the steam pipeline system.

[0003] Currently, most commonly used steam pipeline venting structures rely on simple valve venting devices or traditional steam traps to discharge gas and condensate from the pipeline. When faced with steam under high temperature and high pressure, the condensation effect of these traditional structures often proves inadequate. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] First embodiment: See Figures 1-3 As shown, this utility model provides a steam pipe exhaust structure, including an exhaust pipe 1, which is composed of multiple functional parts connected in sequence: first, an exhaust section 101 directly connected to the exhaust equipment, serving as the initial channel for steam to enter the exhaust structure; a condenser section 102 connected to the movable end of the exhaust section 101, responsible for condensing the steam; and an outlet section 103 connected to the end of the condenser section 102, on which a vacuum pump 2 is installed, for extracting the remaining gas after condensation. The condenser 102 has a V-shaped structure of not less than 100 degrees and is installed at an angle. Both open ends of the condenser 102 extend upward toward the exhaust 101, which helps the steam to flow and condense in the condenser. At the same time, the lower end of the condenser 102 is connected to the liquid tank 3 through a pipe, so that the liquid generated during the condensation process can flow into the liquid tank 3 for collection through the inclined pipe. In addition, a condenser rod 4 is provided inside the condenser section 102 in the high-end direction. The lower end of the condenser rod 4 extends toward the lower end of the condenser section 102. The condenser rod 4 can increase the contact area between the steam and the condenser structure, further promote the condensation effect of the steam in the condenser section 102, and improve the condensation efficiency of the overall exhaust structure.

[0019] The "V" angle of the condenser section 102 is 25°-60°. This ensures that the steam has sufficient residence time in the condenser section to complete condensation, while avoiding excessive steam flow resistance due to an excessively small angle or a decrease in condensation efficiency due to an excessively large angle. When the condenser section 102 contains multiple "V" shaped structures, an arc transition section is provided at the corner connecting two adjacent "V" shaped structures. This transition section can reduce the flow impact of steam at the corner, reduce resistance, and at the same time avoid stress concentration that could damage the pipe structure.

[0020] Preferably, the number of "V"-shaped structures is not less than one, and they are arranged in a continuous manner. The continuous arrangement of multiple "V"-shaped structures can extend the flow path of steam in the exhaust structure, increase the contact time and area between steam and the condensation structure, and further improve the condensation effect of steam. For steam with a large discharge volume or requiring deep condensation, the continuously arranged "V"-shaped structures can gradually reduce the steam temperature through a multi-stage condensation process, improve the condensation efficiency, ensure that the moisture in the steam is fully condensed and collected in the liquid chamber 3, and reduce the moisture content in the uncondensed gas.

[0021] The bottom of the liquid tank 3 is equipped with a drain valve, which allows the liquid to be drained when the condensate collected in the liquid tank 3 reaches a certain amount or when cleaning is required. The side wall of the liquid tank 3 is equipped with a transparent liquid level observation window with liquid level scale lines marked on it. The staff can intuitively understand the amount of liquid stored in the tank through the observation window, and can more accurately judge the liquid level height, which is convenient for timely drainage or maintenance operations.

[0022] The end of the exhaust section 101 that connects to the exhaust equipment is provided with an annular sealing flange, and a high-temperature resistant sealing gasket is provided between the sealing flange and the exhaust section 101.

[0023] The second embodiment differs from the first embodiment in that: The condenser rod 4 is made of metal and has a straight structure. The good thermal conductivity of metal can enhance the steam condensation effect. At the same time, the overall straight structure of the condenser rod 4 facilitates its installation inside the condenser section 102. The condenser rod 4 is provided with a support leg 401 that contacts and supports the inner wall of the condenser section 102. The support leg 401 contacts the inner wall of the condenser section 102 and forms a support.

[0024] The high end of the condenser rod 4 is provided with a sealing cover 402, which can seal the connection between the condenser rod 4 and the condenser part 102 to prevent steam from leaking from the installation point of the condenser rod 4. The condenser section 102 is provided with openings corresponding to the condenser rod 4 and the support leg 401. The openings match the position and size of the condenser rod 4 and the support leg 401 to ensure that the condenser rod 4 and the support leg 401 can be installed.

[0025] The condenser rod 4 has a hollow internal structure. The sealing cover 402 is equipped with a heat transfer tube 5 that extends into the condenser rod 4. The heat transfer tube 5 is U-shaped, which can increase the contact area between the heat transfer tube 5 and the interior of the condenser rod 4 and improve the heat exchange efficiency. The two open ends of the heat transfer tube 5 extend through the sealing cover 402 to the outside and are respectively connected to the liquid inlet pipe and the return pipe to form a complete circulation path. The liquid inlet pipe or the return pipe is also equipped with a liquid supply pump, which realizes the circulation and transportation of the heat transfer medium through the power of the pump body. The exhaust section 103 is designed at an angle, with its upper end extending away from the condenser section 102. This angled arrangement helps the remaining gas after condensation to flow more smoothly under the action of the vacuum pump 2, reducing gas retention in the exhaust section 103 and ensuring the stability of the exhaust process.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
