Description

Technical Field

[0001] The utility model relates to the technical field of coalescing separators, in particular to a liquid-liquid coalescing separator structure. Background Art

[0002] In the process of petrochemical production, coalescing separators are required. Coalescing separators are mainly designed for liquid-liquid separation and contain two types of filter elements, namely: coalescing filter elements and separation filter elements. For example, in an oil-water removal system, when the oil product flows into the coalescing separator, it first flows through the coalescing filter element, which filters out solid impurities and coalesces extremely small water droplets into larger water beads. Most of the coalesced water beads can be separated from the oil by their own weight and settle into the water collection tank. Then the oil product flows through the separation filter element again. Since the separation filter element has good oil wettability and water repellency, water is further separated. Finally, the clean and water-free oil product flows out of the coalescing separator.

[0003] In the existing coalescing separator, the coalescing filter element and the separation filter element inside it are only divided into upper and lower parts, but no isolation structure is set, resulting in a short flow path of the liquid phase when flowing through the coalescing filter element or the separation filter element, and thus the overall separation effect of the liquid phase is not good. Therefore, there is an urgent need for a liquid-liquid coalescing separator structure to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a liquid-liquid coalescing separator structure. Its advantage lies in that it can make the liquid phase inside the tank body flow in a snake shape, thereby effectively extending the flow path of the liquid phase inside the separation filter element and the coalescing filter element, and further improving the separation effect of the separator on the liquid phase, meeting people's usage requirements.

[0036] Refer to Figures 1 - 5, A liquid-liquid coalescence separator structure, including a tank body 1. The two ends of the tank body 1 are respectively connected with a front end cover 2 and a rear end cover 7 through bolts. Inside the tank body 1, a coalescence filter element 13 and a separation filter element 11 are respectively arranged. The separation filter element 11 is arranged above the coalescence filter element 13. On one side outer wall of the front end cover 2, a liquid inlet pipe 3 and a liquid discharge pipe 4 are respectively fixedly connected. The liquid discharge pipe 4 is located above the liquid inlet pipe 3. A second sewage discharge pipe 9 and a first sewage discharge pipe 6 are respectively arranged at the bottom and one side of the tank body 1. One ends of the first sewage discharge pipe 6 and the second sewage discharge pipe 9 are both provided with sealing covers 5, which can make the liquid phase inside the tank body 1 flow in a snake shape, thereby effectively extending the flow path of the liquid phase inside the separation filter element 11 and the coalescence filter element 13, and further improving the separation effect of the separator on the liquid phase, meeting the usage requirements of people.

[0037] Specifically, a handle 8 is fixedly connected to one side outer wall of the rear end cover 7, which can facilitate the staff to quickly disassemble or install the rear end cover 7.

[0038] Specifically, a central partition plate 12 is fixedly connected inside the tank body 1. The central partition plate 12 is arranged on both sides of the separation filter element 11 and the coalescence filter element 13, which can effectively isolate the separation filter element 11 and the coalescence filter element 13, ensuring the separation and filtration effects of the separation filter element 11 and the coalescence filter element 13 on the liquid phase.

[0039] Specifically, an extension plate 17 is fixedly connected to one side outer wall of the central partition plate 12. The side of the extension plate 17 away from the central partition plate 12 is in contact with one side outer wall of the rear end cover 7, which can isolate the coalescence filter element 13 located above and the separation filter element 11 located below, ensuring that the liquid phase flows in a snake shape inside the tank body 1.

[0040] Specifically, two groups of second arc-shaped plates 19 are fixedly connected inside the tank body 1. The two groups of second arc-shaped plates 19 respectively separate the separation filter element 11 and the coalescence filter element 13. One end of the second arc-shaped plate 19 is flush with one end of the tank body 1, ensuring that the liquid phase flowing into the lower coalescence filter element 13 can flow into the coalescence filter element 13 located above.

[0041] Specifically, a second fitting plate 18 is fixedly connected to the circumferential inner wall of the tank body 1. One ends of the separation filter element 11 and the coalescence filter element 13 are fixedly connected to one side outer wall of the second fitting plate 18 through bolts, ensuring the overall stability after the separation filter element 11 and the coalescence filter element 13 are installed.

[0042] Specifically, one end of the second arc-shaped plate 19 is fixedly connected to a first arc-shaped plate 10. The end of the first arc-shaped plate 10 away from the second arc-shaped plate 19 is in contact with one side inner wall of the front end cover 2, which can play a good isolation role and prevent the separated impurities or water from mixing with the liquid phase again.

[0043] Specifically, a support pipe 15 is fixedly connected to an inner wall of the front end cover 2. One end of the support pipe 15 is inserted into the inside of the separation filter element 11 or the coalescence filter element 13. Equally spaced circular through grooves 16 are formed in the circumferential outer wall of the support pipe 15. A first fitting plate 14 is fixedly connected to the circumferential outer wall of the support pipe 15. One side of the first fitting plate 14 abuts against one end of the separation filter element 11 or the coalescence filter element 13. The support pipe 15 can ensure the stability of the separation filter element 11 and the coalescence filter element 13 after installation inside the tank body 1.

[0044] Working principle: When it is necessary to separate the liquid phase, it can be first injected into the inside of the tank body 1 through the liquid inlet pipe 3. After the liquid phase enters the inside of the tank body 1, it will flow into the coalescence filter element 13 located below after being blocked by the first arc-shaped plate 10. Subsequently, the liquid phase flows to the other end after being filtered by the lower coalescence filter element 13. The liquid phase flowing to the other end will flow into the upper coalescence filter element 13 again for secondary filtration. The liquid phase after secondary filtration will flow into the separation filter element 11 for separation, and finally flows out from the drain pipe 4 at one end of the front end cover 2. Moreover, the impurities and water generated during the filtration and separation processes can be discharged from the inside of the first drain pipe 6 and the second drain pipe 9. The entire separation process can make the liquid phase inside the tank body 1 flow in a snake-like manner, thereby effectively extending the flow path of the liquid phase inside the separation filter element 11 and the coalescence filter element 13, and further improving the separation effect of the separator on the liquid phase, meeting the usage requirements of people.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
