Description

Technical Field

[0001] The utility model relates to the field of separators, and more specifically, to a steam-water separator. Background Art

[0002] In steam power systems and industrial processes, steam-water separators are critical pressure vessels, and their structural design directly impacts gas-liquid separation efficiency and system operational stability. Existing steam-water separators typically utilize carbon steel or stainless steel valve bodies with flanged interfaces, forcing them to be installed horizontally on process pipelines.

[0003] Its typical structure (see Appendix Figure 1 ) includes a valve body with inlet and outlet flanges at both ends, a separation plate arranged obliquely inside, and a separation part formed by the downward extension of the middle section of the separation plate. Among them, the separation plate divides the interior of the valve body into an upper cavity and a lower cavity, the outer wall of the separation part and the inner wall of the valve body form a vortex channel, and the interior of the separation part is provided with an exhaust channel connecting the upper and lower cavities. During operation, after the wet steam enters the lower cavity from the inlet end, it is guided by the structure of the separation part and converted from linear motion to spiral motion around the outer wall of the separation part. In this process, the droplets are thrown to the inner wall of the valve body due to centrifugal force, and after collision and aggregation, they are gathered downward along the wall surface, while the dry steam enters the upper cavity through the exhaust channel and is discharged from the outlet end. This traditional structure has exposed technical defects in actual application. During separation, the liquid separation is not sufficient. Therefore, there is an urgent need to develop a high-efficiency steam-water separation device with a new separation structure. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a steam-water separator, comprising a separator, a separation chamber formed in the separator, an inlet end and an outlet end connected to the separation chamber formed at both ends of the separator, a separation plate for separating the separation chamber being obliquely arranged in the separation chamber, a separation portion extending to the lower end of the separation plate to form an exhaust channel, and an extension plate protruding from the upper end of the separation plate to be connected to the exhaust channel.

[0006] The utility model has the following effects: an extension plate is extended from the upper end of the separation plate, so that the gas continues to rise along the extension plate when passing through the exhaust channel, and the gas stays in the exhaust channel longer. The unseparated water in the gas can be separated and retained along the extension plate, so that the separator has a better separation effect. At the same time, the extension plate is closer to the upper end of the separator (valve body).

[0009] The utility model is further configured as follows: a water outlet section is formed on one side of the separation plate close to the outlet end, and a water outlet gap is formed between the water outlet section and the separator.

[0010] The utility model has the following effects: since the existing separation plates are all inclined and the outlet end is usually at the lower end, the above structure forms a water outlet gap on one side of the outlet end so that water can flow into the lower end of the separator (valve body) from the water outlet gap, which is convenient for drainage.

[0029] Reference Figures 1 to 2 The embodiments of the present invention are further described.

[0030] A steam-water separator includes a separator 1, wherein a separation chamber 2 is formed in the separator 1, and an inlet end 21 and an outlet end 22 connected to the separation chamber 2 are formed at both ends of the separator 1. A separation plate 3 is obliquely provided in the separation chamber 2 to separate the separation chamber 2, and the separation plate 61 extends a separation portion toward the lower end to form an exhaust channel 4, and the separation plate 3 protrudes from the upper end to form an extension plate 41 connected to the exhaust channel 4. An extension plate 41 extends from the upper end of the separation plate 3, so that the gas continues to rise along the extension plate 41 when passing through the exhaust channel 4. The gas stays in the exhaust channel 4 for a longer time, and the unseparated moisture in the gas can be separated and retained along the extension plate 41, so that the separator 1 has a better separation effect. At the same time, the extension plate 41 is closer to the upper end of the separator 1 (valve body). After leaving the exhaust channel 4, the gas will impact the upper end of the separator 1 (valve body), and the moisture in the gas will be separated again. Compared with the existing technology, by extending the extension plate 41, the separator 1 has two separations on the original basis, so that the product separation effect is better.

[0031] The upper end of the extension plate 41 is higher than the outlet end 22. The water vapor is guided to the upper end of the separator 1 (valve body), so that the water vapor contacts the upper end of the separator 1 (valve body) and is separated again. The upper end of the extension plate 41 is higher than the outlet end 22, so that the water vapor does not leave the extension plate 41 immediately. The gas sinks and leaves the outlet along this path, and is separated again. The separation is more complete, and the separation effect is better with two separations.

[0032] A water outlet section is formed on one side of the separation plate 3 close to the outlet end 22 , and a water outlet gap 5 is formed between the water outlet section and the separator 1 .

[0033] The water outlet gap 5 is provided on a side close to the outlet end 22. Since the existing separation plates 3 are all inclined, and the outlet end 22 side is usually at the lower end, the above structure forms a water outlet gap 5 on one side of the outlet end 22 so that water can flow from the water outlet gap 5 into the lower end of the separator 1 (valve body), facilitating drainage.

[0034] The separation portion is rotated to form a separation edge 6. The separation portion is provided with a rotating separation edge 6, which can better guide the water vapor, and at the same time, compared with direct contact with the separation portion, can increase the contact surface and better perform water vapor separation.

[0035] A partition plate 61 is provided at the bottom of the separator 1 .

[0036] The partition plate 61 is provided at the lower end of the exhaust passage 4 to guide the water to fall to the bottom and prevent the water at the bottom from splashing and entering the exhaust passage 4.

[0037] The upper end of the separator 1 (valve body) is equipped with a lifting nut 7 to facilitate subsequent lifting and movement. A drain outlet 71 is provided at the lower end of the separator 1 (valve body). Steam enters through the inlet end 21 and spirals downward around the separation edge 6 on the separation portion. The separated water falls along the separation portion. After passing through the extension plate 41, it is also separated within the exhaust channel 4. The water can fall along the exhaust channel 4, then impact the upper end of the separator 1 (valve body) and is separated in the upper chamber 231. The water then flows down the separation plate 3 through the water outlet gap 5 into the lower chamber 232.

[0038] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
