Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation, in particular to a secondary gas-liquid separation device for reducing COD of condensed water. Background Art

[0002] Gas-liquid separation is a technology that uses the density difference or other physical properties of gas and liquid to separate them. Specifically, due to the different densities of gas and liquid, the liquid will settle at the bottom of the container under the action of gravity, while the gas will remain at the top, thus achieving separation. This is achieved through a specific device - a gas-liquid separator.

[0003] The function of the existing gas-liquid separation device is to remove the solution entrained in the steam in a timely manner, thereby reducing the COD in the condensate, ensuring the stability of the steam calorific value, and ensuring the heat exchange rate. However, the existing gas-liquid separation device is difficult to completely separate the entrained liquid, which affects the water quality of the condensate at the outlet. Therefore, it is necessary to propose a secondary gas-liquid separation device that can fully separate the liquid entrained in the steam. Utility Model Content

[0031] The primary separation tank 11 is used for primary separation of the vapor containing the solution, and the secondary separation tank 12 is used for secondary separation of the gas after the primary separation. The feed pipe 13 is used for the vapor containing the solution to enter the primary separation tank 11, the connecting pipe 14 is used for the gas after the primary separation to enter the secondary separation tank 12, the discharge pipe 15 is used to transport the separated liquid to the outside, the transmission pipe 16 is used to transport the liquid in the secondary separation tank 12 to the discharge pipe 15, and the external transmission pipe 17 is used to transport the separated gas to the outside.

[0032] Auxiliary separation assembly, the auxiliary separation assembly includes a vertical slot 21, a slider 22, a high-efficiency juice collector 23, a vertical pipe 24 and a connecting rod 25; the vertical slot 21 is opened on both sides of the first separation tank 11, the slider 22 is slidably connected to the interior of the vertical slot 21, the high-efficiency juice collector 23 is fixed between the opposite ends of the slider 22, the vertical pipe 24 is fixed to the center of the high-efficiency juice collector 23, and the connecting rod 25 is threadedly connected to the interior of the vertical pipe 24;

[0033] The vertical groove 21 is used for connecting and moving the slider 22, the slider 22 is used for connecting the high-efficiency juice collector 23, the high-efficiency juice collector 23 is used to adsorb the solution, the vertical pipe 24 is used for threaded connection of the connecting rod 25, and the connecting rod 25 is used to drive the movement of the vertical pipe 24.

[0034] A set of fixing brackets 27 are fixedly connected to the upper part of the first-stage separation tank 11, and connecting plates 26 are fixedly connected between the inner sides of the fixing brackets 27;

[0035] A rotating rod 28 is rotatably connected between the connecting plates 26. The bottom end of the rotating rod 28 passes through the bottom of the connecting plate 26 and is fixedly connected to the top end of the connecting rod 25.

[0036] The fixing frame 27 is used for connecting the connecting plate 26, and the connecting plate 26 is used for connecting the rotating rod 28. The rotating rod 28 is used to drive the connecting rod 25 to rotate. By rotating the connecting rod 25, the connecting rod 25 drives the rotating rod 28 to rotate inside the connecting plate 26, prompting the connecting rod 25 to rotate, so that the connecting rod 25 drives the vertical pipe 24 to rotate through the thread, so that the vertical pipe 24 drives the high-efficiency juice collector 23 to move through the slider 22 and the vertical slot 21.

[0037] Working principle: During separation, steam enters the primary separation tank 11 through the feed pipe 13, and then enters the high-efficiency juice collector 23. The steam passes through the high-efficiency juice collector 23, causing the suspended liquid to collide with the high-efficiency juice collector 23 and be adsorbed. When the droplets grow to a certain size, they fall into the discharge pipe 15 due to gravity. The steam after separating the liquid enters the secondary separation tank 12 through the connecting pipe 14, and the steam spins at high speed to throw out its own liquid. The condensed water enters the discharge pipe 15 through the transmission pipe 16 due to gravity and is discharged from the discharge pipe 15. The steam The juice is discharged through the external delivery pipe 17; when cleaning the high-efficiency juice catcher 23, open the bottom of the first-stage separation tank 11 and manually rotate the bottom end of the connecting rod 25 so that the connecting rod 25 drives the rotating rod 28 to rotate inside the connecting plate 26, prompting the connecting rod 25 to rotate, so that the connecting rod 25 drives the vertical pipe 24 to rotate through the thread, thereby causing the vertical pipe 24 to push the slider 22 to move in the vertical groove 21 through the high-efficiency juice catcher 23, thereby causing the connecting rod 25 to push the high-efficiency juice catcher 23 downward. When it moves down to the rubber pad 34, the high-efficiency juice catcher 23 can be cleaned;

[0038] In the above steps, the efficient juice catcher 23 can be pushed downward by the interaction between the connecting rod 25, the rotating rod 28 and the connecting plate 26.

[0039] See also Figures 1-4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0040] Support components;

[0041] The support assembly includes a guide frame 31, a set of cross bars 32 and a set of support bars 33; the guide frame 31 is fixed to the top of the connecting plate 26, the cross bars 32 are fixed to the outer periphery of the bottom end of the connecting rod 25, and the support bars 33 are fixed to the top of the cross bars 32;

[0042] The guide frame 31 is used to guide the liquid to flow downward, and the cross bar 32 is used to connect the support rods 33. There are four cross bars 32. The support rods 33 are used to connect the rubber pads 34 and support the high-efficiency juice catcher 23 after it moves downward. There are two support rods 33 in each group.

[0043] Both sides of the guide frame 31 are inclined, and the top of the support rod 33 is fixedly connected to the rubber pad 34, and the rotating rod 28 passes through the top of the lower guide frame 31;

[0044] The inclined surface facilitates guiding the flow of liquid, and the rubber pad 34 is used to protect the bottom end of the high-efficiency juice catcher 23. When the high-efficiency juice catcher 23 moves downward, the high-efficiency juice catcher 23 contacts the rubber pad 34, so that the support rod 33 assists in supporting the upper high-efficiency juice catcher 23 through the rubber pad 34.

[0045] Working Principle: When the component is not in use, the high-efficiency juice catcher 23 is located at the center of the inner side of the primary separation tank 11. When the component is in use, steam enters the primary separation tank 11 through the feed pipe 13. When the liquid slides down in the primary separation tank 11, the liquid contacts the guide frame 31, causing the guide frame 31 to guide the liquid downward through the inclined surface. When the high-efficiency juice catcher 23 moves downward, it contacts the rubber pad 34, causing the support rod 33 to provide auxiliary support for the upper high-efficiency juice catcher 23 through the rubber pad 34.
