[0018] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 , Figure 2 As shown, this embodiment discloses a coalescing dewatering device including a first filtration section 1, a connecting section 2, a drainage section 3, and a second filtration section 4. The first filtration section 1 includes a first housing 11 and a filter element assembly 12. The first housing 11 is tubular, with flanges at both ends. One end of the first housing 11 is fitted with an openable flange cover, and the other end of the first housing 11 is connected to the connecting section 2 via a flange. The filter element assembly 12 includes a filter element housing 121 and multiple coalescing filter elements 122. The filter element housing 121 is slidably mounted to the first housing 11, and the filter element housing 121 is connected to the first... Sliding guides are provided between the inner walls of the housing 11. The flange at one end of the first housing 11 extends into the opening to form a limit for the installation depth of the filter element housing 121. Multiple coalescing filter elements 122 are inserted and installed in the filter element housing 121. Each coalescing filter element 122 has a central channel 1221. The raw liquid enters the central channel 1221 and passes through the coalescing filter element 122 under pressure, separating the water in the raw liquid. A filter screen 1222 is installed at the end of the central channel 1221 near the feed. The filter screen 1222 can filter impurities and prevent impurities from entering the central channel 1221.

[0020] The first housing 11 has a feed inlet 111, which is located on the side of the filter element assembly 12 away from the second housing 31. The filter element housing 121 includes a front end plate 1211 and a rear end plate 1212. The front end plate 1211 can be snapped into the coalescing filter element 122. The front end plate 1211 and the coalescing filter element 122 can be fixed together by a latch after the coalescing filter element 122 is installed. The front end plate 1211 is equipped with a handle 1223 to facilitate the removal of the coalescing filter element 122 for cleaning. The rear end plate 1212 is provided with a through hole 1213, which connects to the drainage section 3. The rear end plate 1212 is equipped with a support frame 1214. 14 is provided with a positioning block 1215. One end of the coalescing filter element 122 is inserted into the positioning block 1215. The positioning block 1215 limits the installation of the end of the coalescing filter element 122. After the raw liquid passes through the central channel 1221 of the coalescing filter element 122, it enters the filter element housing 121 and flows to the rear end through the through hole 1213. The first housing 11 is provided with a first differential pressure gauge 112 and a second differential pressure gauge 113, which are used to detect the pressure at the feed end and the pressure after passing through the coalescing filter element 122, respectively. The first housing 11 is also provided with a drain port 114, which is located at the bottom of the feed end of the first housing 11 and can be opened to discharge the impurities in the feed.

[0021] The drainage section 3 includes a second housing 31 and a storage tank 32. One end of the connecting section 2 is connected to the first housing 11, and the other end of the connecting section 2 is connected to the second housing 31. The connecting section 2 is sealed to the first housing 11 and the second housing 31 by a flange. The connecting section 2 is inclined, with the upper end of the connecting section 2 connected to the first housing 11 and the lower end of the connecting section 2 connected to the second housing 31. The inclined connecting section 2 can guide the water separated from the raw liquid to the drainage section 3 located at a lower position. The water separated from the raw liquid has a higher density than the oil and will be located at the bottom of the space during the transmission process. The water droplets will collect at the bottom, so that the separated water can be more efficiently concentrated in the storage tank 32. The connecting section 2 includes a safety valve 21 and a vent 22, which are located at the upper part of the connecting section 2.

[0022] The first housing 11 is connected to the second housing 31. The upper end of the liquid storage tank 32 is connected to the second housing 31. The bottom of the liquid storage tank 32 is provided with a drain outlet 321 for draining the water accumulated in the liquid storage tank 32 from the bottom. The side wall of the liquid storage tank 32 is provided with a boundary gauge 322 and a level gauge 323 for detecting the boundary position between oil and water in the liquid storage tank 32 and the amount of water.

[0023] The second filtration section 4 includes a third housing 41 and a separation filter element 43. The third housing 41 is connected to the second housing 31. The first housing 11, the connecting section 2, the second housing 31, and the third housing 41 are connected by a flange seal. The first filtration section 1, the connecting section 2, the drainage section 3, and the second filtration section 4 are combined and connected to each other by a flange seal. The design of splicing and assembling the various parts greatly reduces the difficulty of production and processing, makes transfer and processing more convenient, reduces costs, and makes transportation more convenient. The third housing 41 is provided with a discharge port 411, which is located at the upper end of the third housing 41. When discharging, the dehydrated oil can be sent out from the top, ensuring that the oil is sent out from the top.

[0024] The third housing 41 is inclined, and the lower end of the third housing 41 is connected to the second housing 31. The inclined second filter section 4 causes water droplets that may be carried in the oil entering the second filter section 4 to flow back to the storage tank 32, so that the separated water components can be stably placed in the storage tank 32. The upper end of the third housing 41 is provided with an opening, and an openable flange cover is installed at the opening. The flange cover can be opened to remove the separator filter element 43 for maintenance.

[0025] The third housing 41 is equipped with a separation filter element 43. The third housing 41 is provided with a support ring 42. One end of the separation filter element 43 abuts against the support ring 42. The center of the support ring 42 is provided with a through hole 1213, which connects to the interior of the separation filter element 43. The outlet 411 connects to the space between the outside of the separation filter element 43 and the third housing 41. The separation filter element 43 is used to separate oil and water in the second filtration section 4. The oil passes through the separation filter element 43 from the inside to the outside to prevent the separated water from being sent out from the outlet 411. The support ring 42 is provided with a limiting ring 421, which extends toward the separation filter element 43 and is inserted into the separation filter element 43. The separation filter element 43 is also provided with a handle for easy cleaning.
