Description

Technical Field

[0001] This application belongs to the field of oil-water separation equipment manufacturing technology, specifically a miniature water and impurity removal and oil purification device. Background Technology

[0002] Most water and impurity removal equipment on the market can only handle free water above 500ppm, and is not effective for emulsified water; or they use vacuum low-temperature evaporation, which has high energy consumption and low efficiency; and the coalescence tank and separation tank in the water and impurity removal equipment are not positioned differently, so water removal relies solely on pump discharge, resulting in low water removal efficiency and poor effect. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a miniature water and impurity removal and oil purification device that places the separation tank above the coalescing tank. This allows the oil to flow upwards after passing through the coalescing filter (demulsifier) ​​in the coalescing tank. At a low flow rate, the coalesced water droplets are more likely to settle downwards and not be washed away by the oil until they settle into the water storage tank. Then, the oil enters the separation tank. This solves the problems of low water removal efficiency and poor effect of existing water and impurity removal equipment.

[0004] The above-mentioned technical objective of this application is achieved through the following technical solution: A miniature water, impurity, and oil purification device includes a frame. From bottom to top, an oil pump, a coalescing tank, and a separating tank are sequentially arranged on the frame. The lower end of the coalescing tank is the oil inlet, and the upper end is the oil outlet. The output end of the oil pump is connected to the oil inlet of the coalescing tank, and the oil outlet of the coalescing tank is connected to the oil inlet of the separating tank. The oil inlet of the separating tank is located at the bottom of the separating tank, and an oil outlet is provided on the side wall of the separating tank. The lower end of the coalescing tank is connected to the water inlet of a water storage tank, which is located below the coalescing tank and is equipped with a drain valve.

[0005] Preferably, the separating tank is located directly above the coalescing tank, and the oil outlet of the coalescing tank is connected to the oil inlet of the separating tank via a straight pipe.

[0006] Preferably, the straight pipe is parallel to the connecting line segment between the separation tank and the coalescing tank.

[0007] Preferably, the water storage tank is equipped with a sight glass.

[0008] Preferably, both the separation tank and the coalescence tank are equipped with pressure gauges.

[0009] Preferably, the lid of the coalescing tank is located on the side wall of the coalescing tank, and the lid of the separating tank is located on the side wall of the separating tank.

[0010] Preferably, the top of the separation tank is provided with an exhaust valve.

[0011] Preferably, the bottom of the frame is provided with casters.

[0012] The beneficial effects of this application are: This application designs a miniature water and impurity removal and oil purification device by placing the separation tank above the coalescing tank. After the oil passes through the coalescing filter element (demulsifier) ​​in the coalescing tank, the oil flows upward. At a low flow rate, it is easier for the coalesced water droplets to settle downward and not be washed away by the oil until they settle into the water storage tank. Then the oil enters the separation tank, which solves the problem of low water removal efficiency and poor effect of existing water and impurity removal equipment. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this application; Figure 2 for Figure 1 A schematic diagram of the structure on the back.

[0014] The components include: 1. frame; 2. oil pump; 3. coalescing tank; 4. separation tank; 5. oil outlet; 6. water storage tank; 7. drain valve; 8. straight pipe; 9. sight glass; 10. exhaust valve; 11. roller; 12. pressure gauge; and 13. power controller. Detailed Implementation

[0015] like Figure 1-2 As shown, a miniature water, impurity, and oil purification device includes a frame 1. From bottom to top, an oil pump 2, a coalescing tank 3, and a separating tank 4 are sequentially arranged on the frame 1. The lower end of the coalescing tank 3 is the oil inlet, and the upper end is the oil outlet. The output end of the oil pump 2 is connected to the oil inlet of the coalescing tank 3, and the oil outlet of the coalescing tank 3 is connected to the oil inlet of the separating tank 4. The oil inlet of the separating tank 4 is located at the bottom of the separating tank 4. An oil outlet 5 is provided on the side wall of the separating tank 4. The lower end of the coalescing tank 3 is connected to the water inlet of a water storage tank 6, which is located below the coalescing tank 3. A drain valve 7 is provided on the water storage tank 6.

[0016] In this embodiment, during use, the oil-water mixture is pumped into the coalescing tank 3 by the oil pump 2. After passing through the coalescing filter (demulsifier) ​​in the coalescing tank 3, the water mixture flows upward. Due to the upward flow, the flow velocity is low under the influence of gravity, which makes it easier for the coalesced water droplets to settle downward and not be washed away by the oil entering the separator 4. The water droplets settle into the water storage tank 6, and then the water in the water storage pipe 6 is discharged through the drain valve 7. The separator 4 is positioned above the coalescing tank 3, so that small water droplets that do not settle in time are intercepted by the separation and sieving in the separator 4, and then settle down to the coalescing tank 3 by their own gravity and continue to settle into the separator 4. Compared with the traditional method of setting the coalescing tank 3 and separator 4 at an elevated position, this arrangement has two advantages: first, it saves space, meaning the entire device is slimmer and easier to store; second, the upward flow of the oil-water mixture results in a slower flow velocity, which facilitates the settling of water droplets. Therefore, the water and impurity removal efficiency is high.

[0017] As a preferred embodiment, the separator 4 is located directly above the coalescing tank 3, and the oil outlet of the coalescing tank 3 is connected to the oil inlet of the separator 4 via a straight pipe 8. This direct-above arrangement, combined with the straight pipe 8, facilitates the direct dripping of water droplets into the water storage tank 6 (the straight pipe 8 is better than a curved pipe, as the water droplets have a shorter path to sink).

[0018] As a preferred embodiment, the straight pipe 8 is parallel to the connecting line segment between the separating tank 4 and the coalescing tank 3. This arrangement greatly reduces the probability of water droplets hitting the inner wall of the straight pipe 8 during their descent (if the straight pipe 8 were tilted, water droplets would likely hit its inner wall), thus improving efficiency. As a preferred embodiment, the water storage tank 6 is equipped with a sight glass 9. The contents of the water storage tank 6 can be directly observed through the sight glass 9.

[0019] As a preferred embodiment, both the separating tank 4 and the coalescing tank 3 are equipped with pressure gauges 12. This allows for direct monitoring of the pressure in the separating tank 4 and the coalescing tank 3, facilitating pressure adjustment within them. As a preferred embodiment, the lid of the coalescing tank 3 is located on the side wall of the coalescing tank 3, and the lid of the separating tank 4 is located on the side wall of the separating tank 4. This arrangement saves space and facilitates the replacement of filter elements inside the coalescing tank 3 and the separating tank 4, allowing the device to move more flexibly in confined spaces.

[0020] As a preferred embodiment, the top of the separator 4 is provided with an exhaust valve 10. By providing the exhaust valve 10, it is easy to adjust the pressure inside the separator 4.

[0021] As a preferred embodiment, the bottom of the frame 1 is provided with casters 11. By providing casters 11, the usage scenario can be changed.

[0022] As a preferred embodiment, the separation tank 4 and the coalescing tank 3 are arranged on one side of the frame 1, and a power controller 13 is arranged on the upper part of the other side of the frame 1. The power controller 13 is electrically connected to the oil pump 2. The oil pump 2 is controlled by the power controller 13 to realize the opening and closing of the entire device. At the same time, this arrangement of the power controller 13 on the upper part of the side of the frame 1 facing away from the coalescing tank 3 increases the utilization rate of the entire frame 1, makes the layout more aesthetically pleasing, and facilitates user operation.
