Description

Technical Field

[0001] The present application relates to the technical field of hydrophobic expansion vessels, and in particular to a hydrophobic expansion energy dissipation device. Background Art

[0002] The drain expansion tank is used to expand and reduce the pressure of the drain in the pressure drain pipeline, separate the steam and drain, and introduce the steam into the heat exchanger or deaerator to make full use of its thermal energy, while the drain is introduced into the drain box and regularly sent to the water supply system, mainly to reduce the pressure. If the high-pressure steam directly enters the condenser, it is easy to cause overpressure in the condenser. It can reduce the pressure and avoid overpressure. At the same time, some of them also have a cooling device to reduce the temperature.

[0003] A Chinese patent with announcement number CN217057117U discloses a hydrophobic expansion tank with an energy dissipation device. Through the arrangement of a valve body, a valve ball, a drain pipe, and a shell, the high-pressure hydrophobic accumulation will drive the valve ball and the drain pipe to rise, so that the high-pressure steam will be discharged from the exhaust pipe, and the hydrophobic will flow into the outlet pipe from the guide hole and be discharged until the liquid level drops. The hydrophobic that has not precipitated steam will not continue to be discharged downward, and the steam and the hydrophobic will re-assemble and separate, and the internal volume can be intermittently expanded, so that the steam and the hydrophobic are efficiently separated. The design is reasonable, the structure is simple, and it can operate automatically. Through the arrangement of the buffer component, the impact of the high-pressure hydrophobic can be buffered, the damage of the hydrophobic expansion tank is prevented, and the service life of the hydrophobic expansion tank is increased.

[0004] However, the internal structure of the hydrophobic expansion container is complex and difficult to clean. After long-term use, impurities or sediments in the hydrophobic expansion container are easily accumulated in the expansion container, causing blockage and affecting the normal hydrophobic expansion effect. Summary of the invention

[0026] like Figure 1and Figure 2 As shown, the present application provides a hydrophobic capacity expansion and energy dissipation device, including a shell 1, a cleaning port is provided on the top of the shell 1, and an adapted sealing cover 2 is provided on the cleaning port. When the interior of the shell 1 needs to be cleaned, the sealing cover 2 is opened, and the interior of the shell 1 is scrubbed with a special cleaning brush. A water inlet pipe 3 is fixedly connected to the bottom of the shell 1, and a water outlet pipe 4 is fixedly connected to one side of the water inlet pipe 3, and one end of the water outlet pipe 4 extends into the water inlet pipe 3 and extends into the shell 1. A dividing cylinder 5 is provided in the shell 1, and a gap is provided between the dividing cylinder 5 and the shell 1, and the gap is communicated with the top of the dividing cylinder 5. Specifically, the dividing cylinder 5 The distance between the top of the cutting cylinder 5 and the bottom of the sealing cover 2 is 5 cm, which ensures the residence time of the drain inside the shell 1, which is convenient for effectively separating water vapor and drain. The bottom of the dividing cylinder 5 is connected to the water inlet pipe 3, and the exhaust pipe 6 is fixedly connected to the upper side of the shell 1. Specifically, the upper end of the dividing cylinder 5 is located below the exhaust pipe 6, which can prevent the drain from being discharged from the exhaust pipe 6. Compared with the prior art, the internal structure of the shell 1 is simple and easy to clean. Regular cleaning of the inside of the shell 1 can prevent impurities or sediments in the drain from accumulating in the expansion device and causing blockage, thereby ensuring the normal drain expansion effect.

[0027] like Figure 2 As shown, the sealing cover 2 is threadedly connected to the shell 1, and a sealing ring 7 is provided at the connection between the sealing cover 2 and the shell 1. The sealing ring 7 is embedded in the sealing cover 2. The gap between the sealing cover 2 and the shell 1 is sealed by the sealing ring 7 to prevent water vapor from leaking from the gap between the sealing cover 2 and the shell 1, causing waste of heat energy in the steam.

[0028] like Figure 1 As shown, handles 8 are symmetrically arranged on the side of the sealing cover 2, and the sealing cover 2 can be easily rotated by the handles 8 to connect or separate the sealing cover 2 from the housing 1.

[0029] like Figure 2 As shown, a plurality of support columns 9 are provided in the shell 1, one end of the support column 9 is fixedly connected to the bottom of the dividing cylinder 5, and the other end of the support column 9 is connected to the bottom of the shell 1. The support for the dividing cylinder 5 is strengthened by the support column 9 to increase the stability of the structure. Specifically, four support columns 9 are arranged, and the four support columns 9 are evenly arranged at the bottom of the dividing cylinder 5.

[0030] like Figure 2 As shown, a accommodating cavity 10 is provided on the inner side of the shell 1, and a water-cooling pipe 11 is wound around the inner wall of the accommodating cavity 10, and both ends of the water-cooling pipe 11 extend to the outside of the shell 1, which can increase the heat exchange time between the cold water in the water-cooling pipe 11 and the shell 1 and effectively reduce the temperature of the hydrophobicity.

[0031] like Figure 1 and Figure 2As shown, a transparent observation window 12 is provided on the sealing cover 2, through which the accumulation of hydrophobic impurities inside the shell 1 can be easily observed, so that the staff can decide whether to clean the inside of the shell 1 according to the actual situation.

[0032] Working principle:

[0033] When using the device, high-pressure drain enters the shell 1 from the water inlet pipe 3, and cold water is introduced into the water-cooling pipe 11 at the same time. The cold water can spirally advance in the water-cooling pipe 11, and the drain flows through the gap between the dividing cylinder 5 and the shell 1. The cold water can fully absorb the heat of the drain in the gap, and the heat exchange effect is good, which can promote the precipitation of steam. The precipitated steam is discharged from the exhaust pipe 6, and the drain flows into the dividing cylinder 5 from the top of the dividing cylinder 5, and is finally discharged from the water outlet pipe 4. When it is necessary to clean the inside of the shell 1, open the sealing cover 2, and then use a special cleaning brush to brush the inside of the shell 1. The internal structure of the shell 1 is simple and convenient to brush.

[0034] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
