Description

Technical Field

[0001] The utility model relates to the technical field of steam generating devices, in particular to a steam-water separation device of steam generating equipment. Background Art

[0002] The steam-water separation device is a commonly used steam-water separation component in steam generating equipment. However, the steam-water separation effect of the separator inside the existing steam separation device is average, and it cannot effectively solve the problems of poor quality of the output steam and high water content in the steam. Therefore, the structure of the existing steam separation device needs to be further improved. Utility Model Content

[0003] The utility model aims to provide a steam-water separation device for steam generating equipment which has good steam-water separation effect and can ensure high steam quality.

[0004] The purpose of the utility model is achieved in this way:

[0005] A steam-water separation device for a steam generating device comprises a steam collecting tank, a water collecting tank and a plurality of heat exchange tube bundles, wherein the steam collecting tank is located above the water collecting tank, the upper and lower ends of the plurality of heat exchange tube bundles are respectively connected to the steam collecting tank and the water collecting tank, the steam collecting tank is provided with a steam inlet and a steam outlet, a baffle is provided at a position corresponding to the steam inlet in the steam collecting tank, a steam uniforming orifice plate is provided in the steam collecting tank, a mesh is provided on the steam uniforming orifice plate, a shutter steam-water separator is provided at a position corresponding to the steam outlet in the steam collecting tank, the shutter steam-water separator comprises a shell, a plurality of shutters are provided in the shell, an inlet is provided at one end of the shell, and the other end of the shell is connected to the steam outlet. The steam-water separation device for a steam generating device of the utility model can separate steam and water in low-quality steam for multiple times, wherein the baffle separates steam by inertia once, the steam uniforming orifice plate throttling separates steam, and the shutter steam-water separator separates steam again, and the low-quality steam is separated for multiple times, and the separation effect is good, and the water in the low-quality steam is separated, so that higher dryness steam can be produced in a smaller steam-water separation space.

[0006] The present invention can also be further improved as follows.

[0007] The shell is provided with a plurality of shutters at intervals along the length direction thereof, so that the shutter steam-water separator has a better separation effect.

[0008] There is a drainage trough at the bottom of the shell, and the separated water flows down to the heat exchange tube bundle and continues to be heated into steam.

[0009] The baffle and the steam uniforming hole plate separate the steam collecting tank into an upper steam chamber and a lower steam chamber. The steam outlet is arranged on the upper steam chamber, the steam inlet is located on the lower steam chamber, and the upper end of the heat exchange tube bundle is connected with the bottom of the lower steam chamber.

[0010] Heat exchange fins are arranged on the outer side wall of the heat exchange tube bundle.

[0011] A flue gas heat exchange box is provided between the steam collecting tank and the water collecting tank. A plurality of heat exchange tube bundles are located in the flue gas heat exchange box. The front and rear sides of the flue gas heat exchange box are open, so as to facilitate the high-temperature flue gas to flow through for heat exchange.

[0012] The heat exchange box is made of heat-insulating materials. The heat-insulating materials are thermal insulation cotton, which can prevent the heat loss of high-temperature flue gas from being serious and reduce the heat exchange efficiency.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The steam-water separation device of the steam generating equipment of the utility model can separate the steam and water in the low-quality steam for multiple times. The baffle separates the steam by inertia once, the steam uniforming orifice plate throttling separates the steam, and the shutter steam-water separator separates the steam again. The low-quality steam is separated for multiple times, and the separation effect is good. The water in the low-quality steam is separated, and the production of higher dryness steam can be achieved in a smaller steam-water separation space.

[0015] 2. The tiny water droplets carried in the steam can be completely separated. In the past, the steam-water separation device of the steam generating equipment did not have a shutter steam-water separator, and the tiny water droplets in the steam could not be completely separated. After the steam was throttled and separated by the front baffle and the uniform steam orifice plate, the wet steam flowed along the inner wall of the shutter component in a curve with frequent changes in speed. At the turning point, the water droplets were thrown onto the wall by the inertial force to form a water film. The protruding cross-section blocked the water film and made it drain downward, preventing the steam from being carried again, and the output steam quality was guaranteed.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1, as Figure 1As shown, a steam-water separation device of a steam generating equipment includes a steam collecting tank 1, a water collecting tank 2 and a plurality of heat exchange tube bundles 8, the steam collecting tank 1 is located above the water collecting tank 2, the upper ends and lower ends of the plurality of heat exchange tube bundles 8 are respectively connected to the steam collecting tank 1 and the water collecting tank 2, a steam inlet 9 and a steam outlet 6 are provided on the steam collecting tank 1, a baffle 3 is provided at a position corresponding to the steam inlet 9 in the steam collecting tank 1, a steam uniforming orifice plate 7 is provided in the steam collecting tank 1, a mesh is provided on the steam uniforming orifice plate 7, a louvered steam-water separator 5 is provided at a position corresponding to the steam outlet 6 in the steam collecting tank 1, the louvered steam-water separator 5 includes an outer shell 51, a plurality of louvers 52 are provided in the outer shell 51, an inlet is provided at one end of the outer shell 51, and the other end of the outer shell 51 is connected to the steam outlet 6.

[0019] As a more specific technical solution of the utility model.

[0020] The housing 51 is provided with a plurality of shutters 52 at intervals along the length direction thereof.

[0021] A drainage groove 53 is provided at the bottom of the housing 51 .

[0022] The baffle 3 and the steam uniforming orifice plate 7 separate the steam collecting tank 1 into an upper steam chamber 11 and a lower steam chamber 12 . The steam outlet 6 is arranged on the upper steam chamber, the steam inlet 9 is located on the lower steam chamber, and the upper end of the heat exchange tube bundle 8 is connected to the bottom of the lower steam chamber 12 .

[0023] Heat exchange fins 81 are provided on the outer side wall of the heat exchange tube bundle 8 .

[0024] A flue gas heat exchange box 10 is provided between the steam collecting tank 1 and the water collecting tank 2. A plurality of heat exchange tube bundles 8 are located in the flue gas heat exchange box, and the front and rear sides of the flue gas heat exchange box are open.

[0025] The heat exchange box is made of heat insulating material.

[0026] The working principle of the utility model is:

[0027] Water vapor (wet steam) enters the steam collecting tank 1 through the steam inlet 9. After the water vapor enters, due to the throttling effect of the baffle 3, the steam speed slows down, and part of the water vapor begins to condense into high-temperature water, while the saturated steam moves upward, passes through the steam uniforming orifice 7 evenly, and enters the upper steam chamber. At this time, the steam uniforming orifice 7 throttles and separates the steam, and high-temperature water will also condense on the steam uniforming orifice 7. Then the steam enters the shutter steam-water separator 5, and the steam passes through multiple shutters 52. The shutters 52 separate the steam and water in the steam again, and high-temperature water will also condense on the shutters 52. After the steam is separated multiple times, the high-temperature water in the steam will be completely separated. At this time, the steam is saturated dry steam, and then discharged from the steam outlet 6. All the high-temperature water flows downward into the heat exchange tube bundle 8 and the water collecting tank 2. When the high-temperature flue gas passes through the flue gas heat exchange box, the high-temperature flue gas will exchange heat with the high-temperature water in the heat exchange tube bundle 8, and the high-temperature water will be heated into steam, and the steam continues to be discharged upward from the steam outlet 6.
