Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to a pipeline-type electro-coalescing dehydrator. Background Technology

[0002] An electrostatic dehydrator is a type of crude oil electrostatic dehydrator that has a high dehydration effect, resulting in crude oil with a water content of only 0.1% after dehydration. It features a long service life and is not easily deformed, making it suitable for use in oil fields and refineries.

[0003] Regarding the existing patent CN111057576B, a tubular electrostatic coalescer is disclosed, comprising an upper electrode plate and a lower electrode plate symmetrically arranged vertically. The upper electrode plate and the lower electrode plate are respectively energized with positive and negative electrodes. A left electrode plate and a right electrode plate are arranged at intervals within the space formed between the upper electrode plate and the lower electrode plate. The top end of the left electrode plate is fixedly connected to the bottom end of the upper electrode plate, and the bottom end of the right electrode plate is fixedly connected to the top end of the lower electrode plate. A pad is provided between the bottom end of the left electrode plate and the top end of the lower electrode plate, and between the top end of the right electrode plate and the bottom end of the upper electrode plate. By arranging the left and right electrode plates at intervals and placing coalescing core plates in between, multiple coalescing core plates are arranged horizontally in sequence to form a hierarchy. The electrostatic interaction of the left and right electrode plates, combined with the hydrophilic and oleophobic properties of the coalescing core plates, causes water droplets in the emulsion to flow to both sides under electrostatic action. Then, under the hydrophilic properties of the multi-stage coalescing core plates, further coalescing and settling occurs, thereby achieving the purpose of efficient dehydration and continuous operation. However, the device has a drawback: the left electrode plate is fixedly connected to the upper electrode plate, the right electrode plate is fixedly connected to the lower electrode plate, the upper electrode plate is fixedly connected to the right electrode plate via a pad, and the left electrode plate is fixedly connected to the lower electrode plate via a pad. This makes it impossible to quickly disassemble and replace multiple electrode plates when they are damaged, which affects maintenance efficiency.

[0004] Therefore, to address the problem that existing multiple electrode plates cannot be easily disassembled and replaced, a pipeline-type electrocoagulation dehydrator can be designed. By pulling multiple sets of insulated handles, multiple electrode plates can be quickly disassembled and replaced, thereby improving maintenance efficiency. Utility Model Content

[0005] To overcome the problem that existing multiple electrode plates cannot be easily disassembled and replaced.

[0006] The technical solution of this utility model is as follows: a pipeline-type electrocoagulation dehydrator, comprising a first positive electrode plate, a second positive electrode plate connected above the first positive electrode plate, four sets of fixing bolts connecting the first and second positive electrode plates, an insulating strip fixedly connected to the bottom of the second positive electrode plate away from the first positive electrode plate, multiple sets of first limiting holes being formed on the side of the insulating strip, the multiple sets of first limiting holes being linearly distributed on the side of the insulating strip, an I-shaped insulating partition connected below the insulating strip, multiple sets of second limiting holes being formed on the side of the I-shaped insulating partition, the second limiting holes... An external gate-shaped mounting plate is fixedly connected to the side of the I-shaped insulating partition. Multiple sets of limiting slide rods are slidably connected inside the gate-shaped mounting plate. These limiting slide rods are welded together to the side of the connecting strip. An insulating handle is fixedly connected to the side of the connecting strip away from the limiting slide rods. A guide plate is fixedly connected to the outer wall of the limiting slide rods. The guide plate is located inside the gate-shaped mounting plate. A return spring is fixedly connected to the side of the guide plate near the I-shaped insulating partition. One end of the return spring is welded to the side of the guide plate, and the other end is welded to the side of the I-shaped insulating partition.

[0007] Preferably, by simultaneously pulling a set of insulating handles on the upper side of the first positive electrode plate and a set of insulating handles on the upper side of the first negative electrode plate, the insulating handles drive the connecting strip outward. When the connecting strip moves outward, it drives multiple sets of limiting slide rods outward. At this time, the multiple sets of limiting slide rods move out of the multiple sets of first limiting insertion holes originally opened in the insulating insert and slide out of the insulating insert through the multiple sets of second limiting insertion holes. This releases the multiple sets of limiting slide rods from limiting the insulating insert, so that the first positive electrode plate and the second positive electrode plate can be lifted up and removed. Then, the multiple sets of fixing bolts connecting the first positive electrode plate and the second positive electrode plate can be removed with a screwdriver, thereby achieving the effect of convenient disassembly of the first positive electrode plate and the second positive electrode plate. The same working principle can also be used to remove the first negative electrode plate and the second negative electrode plate from under the two sets of I-shaped insulating partitions, so that they can be replaced.

[0008] Preferably, slots are provided at the top and bottom of the I-shaped insulating partition, and the inner diameter of the slots is the same as the outer diameter of the insulating strip, and the insulating strip is inserted into the slots.

[0009] Preferably, guide blocks are fixedly connected to both sides of the guide plate, and guide grooves are opened on both sides of the gate-shaped mounting plate, with the two sets of guide blocks slidingly connected in the two sets of guide grooves.

[0010] Preferably, another set of insulating strips is inserted into the lower part of the I-shaped insulating partition via a slot, and the other set of insulating strips is welded to the top of the first negative electrode plate.

[0011] Preferably, the first negative electrode plate is connected to the second negative electrode plate by multiple sets of fixing bolts. A third set of insulating strips is fixedly connected to the top of the second negative electrode plate away from the first negative electrode plate. The third set of insulating strips is inserted into another set of I-shaped insulating partitions. A fourth set of insulating strips is fixedly connected to the bottom of the first positive electrode plate. The fourth set of insulating strips is inserted into another set of I-shaped insulating partitions.

[0012] Preferably, four sets of coalescing core plates are fixedly connected to the top of the second negative electrode plate. Each of the four sets of coalescing core plates has a demulsification hole. The inner diameter of the demulsification hole decreases sequentially with the arrangement of the four sets of coalescing core plates. Through holes are provided between the multiple sets of demulsification holes.

[0013] Preferably, the bottom of the second negative electrode plate is provided with a drain outlet, which is fixedly connected to a water collection tank, and a drain pipe is installed on the side of the bottom of the water collection tank.

[0014] The beneficial effects of this utility model are:

[0015] This pipeline-type electropolymerization dehydrator works by simultaneously pulling a set of insulating handles on the upper side of the first positive electrode plate and a set of insulating handles on the upper side of the first negative electrode plate. The insulating handles move the connecting strip outwards, causing multiple sets of limiting slide rods to move outwards as well. These limiting slide rods then move out of the multiple sets of first limiting holes in the insulating strip and slide out through multiple sets of second limiting holes. This releases the limiting slide rods from their restraints on the insulating strip, allowing the first and second positive electrode plates to be lifted and removed. The multiple sets of fixing bolts connecting the first and second positive electrode plates can then be removed with a screwdriver, facilitating easy disassembly of the first and second positive electrode plates. The same working principle can be used to remove the first and second negative electrode plates from under the two sets of I-shaped insulating partitions for replacement. In summary, this device improves the efficiency of electrode plate replacement, thereby significantly enhancing the efficiency of subsequent maintenance. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: a pipeline-type electrocoagulation dehydrator, including a first positive electrode plate 1, a second positive electrode plate 2 connected above the first positive electrode plate 1, four sets of fixing bolts 3 connecting the first positive electrode plate 1 and the second positive electrode plate 2, an insulating strip 4 fixedly connected to the bottom of the second positive electrode plate 2 away from the first positive electrode plate 1, multiple sets of first limiting holes 5 are provided on the side of the insulating strip 4, the multiple sets of first limiting holes 5 are linearly distributed on the side of the insulating strip 4, an I-shaped insulating partition 6 is connected below the insulating strip 4, multiple sets of second limiting holes 8 are provided on the side of the I-shaped insulating partition 6, a gate-shaped mounting plate 9 is provided outside the second limiting holes 8, the gate-shaped mounting plate 9 is fixedly connected to the side of the I-shaped insulating partition 6, and multiple sets of limiting slide rods 10 are slidably connected inside the gate-shaped mounting plate 9. Limiting slide rods 10 are welded together to the side of connecting strip 11. An insulating handle 12 is fixedly connected to the side of connecting strip 11 away from the multiple sets of limiting slide rods 10. A guide plate 13 is fixedly connected to the outer wall of the multiple sets of limiting slide rods 10. The guide plate 13 is placed inside the door-shaped mounting plate 9. A return spring 16 is fixedly connected to the side of guide plate 13 near I-shaped insulating partition 6. One end of the return spring 16 is welded to the side of guide plate 13, and the other end is welded to the side of I-shaped insulating partition 6. The first positive electrode plate 1 and the second positive electrode plate 2 are used to conduct power to the positive electrode. Four sets of fixing bolts 3 are used to connect the first positive electrode plate 1 and the second positive electrode plate 2. An insulating insert 4 is used to connect the I-shaped insulating partition 6 and different electrode plates. The first limiting insertion hole 5 and the second limiting insertion hole 8 allow the limiting slide rod 10 to slide and insert inside. This achieves the effect of limiting and fixing the insulating insert 4. The guide plate 13 is used to guide the movement of multiple sets of limiting slide rods 10. The return spring 16 deforms and resets the guide plate 13, so that multiple sets of limiting slide rods 10 can automatically move back after being pulled, thus automatically inserting and fixing the insulating insert 4. The I-shaped insulating partition 6 is used to connect two sets of insulating inserts 4, thereby achieving the effect of connecting the positive and negative plates.

[0024] Please see Figure 4 In this embodiment, slots 7 are respectively provided on the upper and lower sides of the I-shaped insulating partition 6. The inner diameter of the slot 7 is the same as the outer diameter of the insulating insert 4. The insulating insert 4 is inserted into the slot 7. Guide blocks 14 are fixedly connected to both sides of the guide plate 13. Guide grooves 15 are respectively provided on both sides of the door-shaped mounting plate 9. The two sets of guide blocks 14 are slidably connected in the two sets of guide grooves 15. The two sets of guide blocks 14 are used to guide the movement of the guide plate 13 and prevent the guide plate 13 from deviating. The two sets of guide grooves 15 limit the sliding of the two sets of guide blocks 14 inside.

[0025] Please see Figure 2In this embodiment, another set of insulating strips 4 are inserted into the lower part of the I-shaped insulating partition 6 via slots 7. The other set of insulating strips 4 are welded to the top of the first negative electrode plate 17. The first negative electrode plate 17 is connected to the second negative electrode plate 18 via multiple sets of fixing bolts 3. A third set of insulating strips 4 is fixedly connected to the top of the second negative electrode plate 18 away from the first negative electrode plate 17. The third set of insulating strips 4 are inserted into another set of I-shaped insulating partitions 6. A fourth set of insulating strips 4 is fixedly connected to the bottom of the first positive electrode plate 1. The fourth set of insulating strips 4 are inserted into another set of I-shaped insulating partitions 6. Four sets of coalescing core plates 19 are fixedly connected to the top of the second negative electrode plate 18. The interior of each of the four sets of coalescing core plates 19 is provided with demulsification holes 20. The inner diameter of the demulsification holes 20 varies with the arrangement of the four sets of coalescing core plates 19. The emulsion is depleted in a progressively decreasing manner. Through holes 21 are provided between multiple sets of demulsifying holes 20. Four sets of coalescing core plates 19 are arranged at equal intervals to form a layer. The electrostatic effect of the first positive electrode plate 1 and the first negative electrode plate 17, combined with the hydrophilic and oleophobic properties of the coalescing core plates 19, causes the water droplets in the emulsion to flow to both sides under the electrostatic effect. Then, under the hydrophilic properties of the four sets of coalescing core plates 19, they further coalesce and settle, thereby achieving a highly efficient dehydration effect. By setting multiple sets of demulsifying holes 20, the laminar emulsion in the pipe will collide with the hydrophilic surface of the coalescing core plates 19 when passing through the four sets of coalescing core plates 19, and then flow in different layers. First, the laminar emulsion collides with the hydrophilic surface, increasing the collision probability between water droplets and increasing the coalescence rate. Second, the laminar emulsion forms turbulence by changing layers, further increasing the collision probability and increasing the coalescence rate.

[0026] Please see Figure 5 In this embodiment, a drain outlet is provided at the bottom of the second negative electrode plate 18, and a water collection tank 22 is fixedly connected to the drain outlet. A drain pipe 23 is installed on the side of the bottom of the water collection tank 22. The water collection tank 22 is used to collect the separated water, and the drain pipe 23 is used to drain the water in the water collection tank 22.

[0027] During operation, by simultaneously pulling a set of insulating handles 12 on the upper side of the first positive electrode plate 1 and a set of insulating handles 12 on the upper side of the first negative electrode plate 17, the insulating handles 12 cause the connecting strip 11 to move outward. When the connecting strip 11 moves outward, it causes multiple sets of limiting slide rods 10 to move outward. At this time, the multiple sets of limiting slide rods 10 move out of the multiple sets of first limiting insertion holes 5 originally opened in the insulating insert 4, and slide out of the insulating insert 4 through the multiple sets of second limiting insertion holes 8. In this way, the multiple sets of limiting slide rods 10 release the limiting effect on the insulating insert 4. This allows the first positive electrode plate 1 and the second positive electrode plate 2 to be lifted and removed. Then, the multiple sets of fixing bolts 3 connecting the first positive electrode plate 1 and the second positive electrode plate 2 can be removed with a screwdriver, thus achieving the effect of convenient disassembly of the first positive electrode plate 1 and the second positive electrode plate 2. The same working principle can also be used to remove the first negative electrode plate 17 and the second negative electrode plate 18 from under the two sets of I-shaped insulating partitions 6, so that they can be replaced. In summary, this device improves the replacement efficiency of the electrode plates, thereby greatly improving the maintenance efficiency of the device in the later stage.

[0028] By following the steps described above and pulling multiple sets of insulated handles 12, multiple electrode plates can be quickly disassembled and replaced, thereby improving maintenance efficiency and solving the problem that multiple electrode plates cannot be easily disassembled and replaced in the past.
