DETAILED DESCRIPTION
[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0021] Figure 1 It is the whole structure schematic view of the oil-water separation device provided by the embodiments of the utility model.
[0022] As Figure 1 The utility model discloses an oil-water separation device, which comprises a first container 1 and a second container 2, the first container is provided with a liquid inlet 11 on one side, an oil phase outlet 12 and a water phase outlet 13 are arranged on the side of the first container 1 away from the liquid inlet 11, and the water phase outlet 13 is located at the bottom of the first container 1, and a hydrophilic coalescence filter core 14 is arranged in the first container 1, the second container 2 is communicated with the water phase outlet 13 at the top, and a water outlet is arranged at the bottom of the second container 2.
[0023] After the liquid to be separated enters the first container 1 through the liquid inlet 11, when the oil-water mixture flows through the hydrophilic coalescence filter core 14, the material of the hydrophilic coalescence filter core 14 has high surface energy, can produce strong interaction with water molecules, so that the water droplets in the oil-water mixture can all condense into larger water droplets on its surface, and the formed water droplets can quickly settle and separate from the oil phase with lower density based on the action of gravity. Therefore, through the arrangement of the hydrophilic coalescence filter core 14, the oil-water mixture in the first container 1 can be more beneficial to be separated, and the water content in the oil phase after separation can be reduced, so that the oil-water separation speed and separation effect can be improved.
[0024] The water phase outlet 13 is arranged at the bottom of the first container 1, which is more conducive to the water phase after settling being discharged from the bottom of the first container 1 to the second container 2, and further being discharged through the water outlet 21 arranged at the bottom of the second container 2. After the oil-water mixture is treated by the oil-water separation device provided by the embodiments, the content of emulsified and free water phase entrained in the discharged oil phase can be ensured to be not more than 10 ppm, and the content of free oil entrained in the discharged water phase can be ensured to be not more than 30 ppm.
[0025] As Figure 1As shown, in one preferred embodiment, the oil phase outlet 12 is located at the top of the first container 1. Since the density of the oil phase is lower than that of the water phase, opening the oil phase outlet 12 at the top makes it easier for the denser water phase to move upward when the oil phase is discharged upward. Therefore, it is more beneficial to reduce the water phase content of the material discharged from the oil phase outlet 12.
[0026] like Figure 1 As shown, in one preferred embodiment, a boundary gauge 22 is provided on the second container 2. The boundary gauge 22 can be used to observe the position of the interface between the water phase and the oil phase in the second container 2, and then determine whether it is necessary to open the outlet 21 to drain water based on the amount of water phase in the second container 2. Two or more boundary gauges 22 can be provided on the second container 2, or a larger boundary gauge can be used to observe a wider range in the second container 2, which is more convenient to use.
[0027] Figure 2 This is a schematic diagram of the structure of the hydrophilic coalescing filter element of the oil-water separation device provided in this embodiment of the utility model.
[0028] like Figure 2 As shown, the hydrophilic coalescing filter element 14 includes at least two layers of microporous wire mesh. The outermost microporous wire mesh is a reinforcing layer 145, and the inner microporous wire mesh is a filter layer made of hydrophilic material. Since the hydrophilic material is generally a hydrophilic modified stainless steel microwire, PTFE or PPS, or other materials with low mechanical strength, the reinforcement layer 145 can maintain the shape of the filter layer, thereby improving the stability of the hydrophilic coalescing filter element 14 during use and extending its service life.
[0029] Furthermore, such as Figure 2 As shown, in one preferred embodiment, the filter layer includes a first filter layer 141, a second filter layer 142, a third filter layer 143, and a fourth filter layer 144 arranged sequentially from the inside out. The pore size of the filter layers from the first filter layer 141 to the fourth filter layer 144 gradually increases, allowing larger water droplets to be adsorbed and condensed on the filter layer located downstream in the water flow direction. This enables smaller water droplets that condense upstream but fail to settle to further condense into larger droplets and settle on the filter layer downstream, thus improving the efficiency and effect of oil-water separation. In one specific embodiment, the pore size of the first filter layer 141 is 3-6 μm, the pore size of the second filter layer 142 is 5-10 μm, the pore size of the third filter layer 143 is 10-15 μm, the pore size of the fourth filter layer 144 is 15-20 μm, and the outermost reinforcing layer 145 is made of stainless steel of S31603 or higher with a pore size of 50-100 μm.
[0030] In addition, the filter layer can also adopt other numbers and pore diameters, such as three layers, five layers or more, and the like, and the above embodiments are only used for explaining the technical scheme of the utility model and should not be regarded as a limitation on the protection scope.
[0031] As shown in the drawings, Figure 2 In one preferred embodiment, the hydrophilic coagulation filter element 14 is provided in the first container 1, and a partition plate 15 is also provided in the first container 1. The partition plate 15 is installed on the radial cross section of the first container 1, and is located at the downstream end of the liquid inlet 11, the upstream end of the water phase outlet 12 and the oil phase outlet 13. The partition plate is provided with mounting holes corresponding to the number of the hydrophilic coagulation filter element 14, for mounting the hydrophilic coagulation filter element 14. When the partition plate 15 is installed in the first container 1, the first container 1 can be divided, so that the liquid phase entering the liquid inlet 11 can only flow to the downstream end through the mounting holes on the partition plate 15 and the hydrophilic coagulation filter element 14, thereby improving the oil-water separation efficiency and separation effect.
[0032] At the same time, when assembling the oil-water separation device, the partition plate 15 and the plurality of hydrophilic coagulation filter elements 14 can be assembled first, and then the partition plate 15 can be installed in the first container 1, so that the hydrophilic coagulation filter elements 14 can be installed in the first container 1 at the same time. When disassembling, the hydrophilic coagulation filter elements 14 can be removed at the same time by removing the partition plate 15, thereby improving the convenience of use.
[0033] In addition, the hydrophilic coagulation filter element 14 can also be installed in the first container 1 in other ways. The above embodiments are only preferred embodiments and should not be regarded as a limitation on the protection scope of the utility model.
[0034] As shown in the drawings, Figure 2 In one preferred embodiment, the hydrophilic coagulation filter element 14 is provided in the first container 1, and a partition plate 15 is also provided in the first container 1. The partition plate 15 is installed on the radial cross section of the first container 1, and is located at the downstream end of the liquid inlet 11, the upstream end of the water phase outlet 12 and the oil phase outlet 13. The partition plate is provided with mounting holes corresponding to the number of the hydrophilic coagulation filter element 14, for mounting the hydrophilic coagulation filter element 14. When the partition plate 15 is installed in the first container 1, the first container 1 can be divided, so that the liquid phase entering the liquid inlet 11 can only flow to the downstream end through the mounting holes on the partition plate 15 and the hydrophilic coagulation filter element 14, thereby improving the oil-water separation efficiency and separation effect.
[0035] In addition, in the embodiment shown in the drawings, Figure 2 In the embodiment shown in the drawings, the plurality of hydrophilic coagulation filter elements 14 are arranged in the first container 1 along the axial direction. At this time, the number and installation position of the hydrophilic coagulation filter elements 14 can be appropriately controlled to avoid the projections of the plurality of hydrophilic coagulation filter elements 14 on the horizontal plane from overlapping each other. In this way, the water droplets coagulated on the upper hydrophilic coagulation filter element 14 can directly sink to the bottom of the first container 1 when sinking, so as to smoothly flow to the water phase outlet 13, and will not fall on other hydrophilic coagulation filter elements 14 to affect the sinking speed of the water phase and further affect the separation efficiency.
[0036] Figure 3It is the structural schematic view of the filter unit of the oil-water separation device provided by the embodiment of the utility model.
[0037] As Figure 1 With Figure 3 As shown in one of the preferred embodiments, the oil-water separation device further comprises a third container 3, which is communicated with the upstream end of the liquid inlet 11, and a filter unit is arranged in the third container 3. By connecting the third container 3 to the upstream end of the first container 1 and arranging the filter unit in the third container, the solid impurities in the material can be removed by filtration before entering the first container 1, so as to protect the hydrophilic coagulation filter core 14 from being damaged by these impurities.
[0038] As Figure 3 As shown, the filter unit comprises a shell 31, the outlet of the shell 31 is connected to the liquid inlet 11 of the first container 1, the shell 31 is communicated with the material to be separated through an external interface 33, and a filter core 32 is arranged at the inlet of the shell 31. When the material to be separated flows into the first container 1, it first flows through the filter core 32 in the shell 31, so as to ensure the filtering effect.
[0039] Further, as Figure 3 As shown, the filter core 32 can comprise a mounting plate 321, which is in a ring structure, and has a liquid phase inlet 323 in the inside, which is communicated with the inlet of the shell 31. A filter screen 322 is connected to the ring-shaped end face of the mounting plate 321, which is in a mesh bag structure. When the liquid phase enters the shell 31 through the liquid phase inlet 323, it can spread around and flow through the mesh bag-shaped filter screen 322, and the large-particle impurities are blocked by the filter screen 322 and retained in the inside of the filter screen 322.
[0040] In addition, the filter unit can also adopt other types of filter structures and other installation methods, for example, an activated carbon filter core is arranged in the third container 3, as long as the liquid phase entering the first container 1 can be pre-filtered, which will not be described here.
[0041] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced without departing from the spirit and scope of the utility model, and they should be covered in the scope of the claims of the utility model.
