Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation devices, and in particular to a novel columnar cyclone group oil-water separation device and method. Background Art

[0002] Oil-water separation technology plays a vital role in many fields such as industrial production, environmental protection and daily life.

[0003] The reference patent (publication number: CN214914199U; publication date: 2021-11-30) relates to a new type of columnar cyclone gas-liquid separation device, specifically including: a separation device shell, which is a columnar cavity structure; a gas-liquid inlet pipe, which is arranged on the outside of the separation device shell, and one end of which is through-connected with the middle part of the separation device shell; a liquid phase discharge port, which is arranged at the center position of the bottom of the separation device shell; a separation cylinder, which is a columnar cavity structure with a closed top and an open bottom arranged in the separation device shell, and its upper part is through-connected with one end of the gas-liquid inlet pipe; a plurality of cyclone plates, which are fixedly installed on the inner wall of the separation cylinder; a gas phase collection chamber, which is a cavity structure between the inside of the separation device shell and the separation cylinder; a plurality of guide cyclone plates, which are fixedly installed on the outer wall of the separation cylinder and a gas phase discharge port, which are arranged on the upper part of the separation device shell.

[0004] The new cylindrical cyclone oil-water separator uses the centrifugal force generated by the cyclone to separate oil and water. Due to the different densities of the oil phase and the water phase, the centrifugal force generated in the cyclone chamber is also different. The heavy water phase moves along the wall to the bottom flow port due to the larger centrifugal force and is finally discharged from the bottom flow port; while the light oil phase migrates to the central axis area and flows out from the overflow port after converging.

[0005] However, the traditional device lacks effective pretreatment means before the oil and water enter the separation process, resulting in a large amount of solid particles, suspended matter and other impurities entering the separation device together with the oil and water. These impurities not only interfere with the normal separation process of the oil and water, but also easily cause blockage inside the device, affecting the separation efficiency and increasing the difficulty of maintenance. At the same time, key components such as cyclone plates of traditional devices often adopt a fixed design, which is difficult to flexibly adjust according to changes in the processing volume. After long-term use, these components are prone to accumulate residues and impurities, and are difficult to effectively clean and replace, further reducing the separation efficiency and the service life of the device. For this reason, the present invention provides a novel columnar cyclone group oil-water separation device and method.

At the same time, key components such as cyclone plates of traditional devices often adopt a fixed design, which is difficult to flexibly adjust according to changes in the processing volume.

The rotation of the fan blades not only promotes the flow of oil and water, but also drives the rotation of the filter cartridge, which helps to shake off impurities attached to the surface of the filter cartridge, thereby keeping the filter cartridge clean and unobstructed, effectively avoiding the occurrence of clogging problems, and improving the efficiency of subsequent oil-water separation. The feed housing is installed and disassembled on the separation device housing through the first mounting plate and bolts. Through the early impurity filtration, solid particles, suspended matter and other impurities in the liquid can be effectively removed, avoiding these impurities from interfering with the subsequent oil-water separation process, thereby improving the overall separation efficiency.

[0024] Secondly, the discharge shell provided in the present invention is installed and disassembled between the separation device shell through the bolts on the second mounting plate, and then the second mounting plate is fixedly connected to the support plate through the connecting rod, and the support plate is fixedly connected to the lowest end of the multiple groups of swirl plates. When the second mounting plate is disassembled from the separation device shell through the bolts, the internal swirl plate is directly slid out along the slide groove through the sliding bolt, which is convenient for the disassembly and cleaning of the swirl plate.

[0025] Thirdly, the present invention connects a water pipe to the outside of the water inlet pipe, and then injects water into the annular pipe, and flushes the inside of the device through multiple groups of nozzles, which can effectively remove residues and impurities inside the device and keep the device clean. The operation is simple and convenient, and the filtered oil and water can be evenly distributed on the swirl plate through the evenly distributed through holes. The even distribution of oil and water helps the swirl plate to better exert its separation function, so that oil droplets and water droplets can be more effectively separated, thereby improving the overall oil-water separation efficiency.

[0042] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0043] The present invention also discloses a novel columnar cyclone group oil-water separation method, comprising the following steps:

[0044] S1. The oil-water mixture to be separated is sent into the feed housing 201 through the feed pipe 2. The oil-water mixture after being filtered by the filter cartridge 205 enters the interior of the separation device housing 1 through the first mounting plate 202 and the feed pipe 2. Specifically, the feed housing 201 is provided for the entry of oil and water, and then the oil and water are filtered by the filter cartridge 205 and sent to the interior of the separation device housing 1 through the first mounting plate 202 and the feed pipe 2.

[0045] S2. Then the oil and water pass through the swirl plate, and the oil-water mixture generates a swirl under the action of the swirl plate. According to the density difference, the oil and water are separated inside the device.

[0046] S3. Finally, the first swirl plate 304 and the second swirl plate 305 are spliced ​​together using a splicing assembly, and the number is adjusted according to the number. Then, the first swirl plate 304 and the second swirl plate 305 are slid out of the separation device housing 1 through the sliding bolt 501 and the sliding groove 5 for cleaning. Specifically, the locking block 406 is compressed on the fixed plate 404 at the center of the cavity groove through the spring 405 and the telescopic sleeve rod 407. The locking block 406 shrinks inside the card block 403, and then the first swirl plate 304 is inserted into the card slot bracket 401 at the center of the second swirl plate 305 through the card block 403. Inside, the locking block 406 is then engaged with the locking groove 402 by the action of the spring 405, so that the first swirl plate 304 and the second swirl plate 305 are spliced ​​and used, and then the second mounting plate 3 is fixedly connected to the support plate 303 through the connecting rod 302, and the support plate 303 is fixedly connected to the lowermost one of the multiple groups of swirl plates.

[0047] During operation, the feed housing 201 is used to prevent the entry of oil and water, which are then filtered by the filter cartridge 205 and fed into the interior of the separation device housing 1 through the first mounting plate 202 and the feed pipe 2. When the oil and water enter the interior of the feed housing 201, they first contact the fan blades 206. The fan blades 206 are squeezed by the oil and water, driving the filter cartridge 205 to rotate inside the slide rail bracket 203 through the slide rod 204. The rotation of the fan blades 206 not only promotes the flow of oil and water, but also drives the rotation of the filter cartridge 205, which helps to shake off impurities attached to the surface of the filter cartridge 205, thereby keeping the filter cartridge clean and unobstructed, effectively avoiding the occurrence of blockage problems, and improving the efficiency of subsequent oil-water separation.

[0048] The locking block 406 is pressed and compressed on the fixed plate 404 at the center of the cavity groove through the spring 405 and the telescopic sleeve rod 407, and the locking block 406 is retracted inside the clamping block 403, and then the first cyclone plate 304 is inserted into the inside of the clamping slot bracket 401 at the center of the second cyclone plate 305 through the clamping block 403, and then the locking block 406 is engaged with the locking slot 402 under the action of the spring 405, so that the first cyclone plate 304 and the second cyclone plate 305 can be spliced ​​and used, and the number can be adjusted. When the processing volume is large, the number of cyclone plates can be increased to improve the separation efficiency;

[0049] The set discharge shell 301 is installed and disassembled between the separation device shell 1 through the bolts on the second mounting plate 3, and then the second mounting plate 3 is fixedly connected to the support plate 303 through the connecting rod 302, and the support plate 303 is fixedly connected to the lowermost one of the multiple groups of swirl plates.
