Description

Technical Field

[0001] The embodiments of the present invention relate to the field of oily wastewater treatment technology, specifically to an oily wastewater treatment device and method. Background Technology

[0002] In the industrial production sector, various types of oily wastewater are always discharged. In addition to the large amount of oily wastewater discharged from the oil extraction and processing industry, there is also some oily wastewater discharged from solid fuel thermal processing, wool washing wastewater in the textile industry, leather tanning wastewater in the light industry, railway and transportation industry, slaughtering and food processing, and turning processes in the machinery industry. Existing technology distinguishes oily wastewater from wastewater with ordinary chemical components and carries out targeted oil removal operations for oily wastewater.

[0003] In existing technologies, a relatively quick way to remove oily components from oily wastewater is to use a hydrocyclone structure to treat the wastewater. The hydrocyclone structure is designed with a spiral flow channel inside. After the oily wastewater is transported into the hydrocyclone structure, it flows rapidly within the spiral flow channel. Under the action of the spiral flow channel, centrifugal force is generated during the flow of the oily wastewater. Utilizing the immiscibility between oil and water, the oily components are separated to the central area of ​​the hydrocyclone structure, thus achieving the purpose of separating the wastewater from the oily components and removing the formed elements from the oily wastewater.

[0004] In existing technologies, multiple hydrocyclone structures are typically installed within an installation cylinder, allowing oily wastewater to flow simultaneously into each structure. However, in practical applications, the amount of oily wastewater generated during industrial production is not constant. When the amount of oily wastewater is low, the conveying pressure is affected. When the conveying pressure of the oily wastewater entering the multiple hydrocyclone structures is low, the separation effect of the oily wastewater within the hydrocyclone structures is affected, as is the normal conveying of the oily wastewater. Furthermore, if the oily wastewater is stored to a certain level before treatment, it hinders timely treatment of the oily wastewater. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide an oily wastewater treatment device and method to solve the technical problem in the prior art that when the amount of oily wastewater generated in the industrial production process is small, it is difficult to separate the oily wastewater among multiple hydrocyclone structures, and to maintain the continuous delivery of oily wastewater.

[0006] The present invention provides an oily wastewater treatment device, comprising an installation cylinder, and further comprising: A cyclone oil removal structure is provided, wherein multiple cyclone oil removal structures are arranged in an arc shape inside the mounting cylinder; The slag removal box is fixedly connected to the top side of the mounting cylinder. Oily wastewater passes through the slag removal box to remove residual wastewater. The wastewater conveying structure is provided between the slag removal box and the multiple cyclone oil removal structures. Each cyclone oil removal structure is provided with a top-out communication component to connect the corresponding cyclone oil removal structure with the wastewater conveying structure, so as to treat a small amount of oily wastewater. A circumferential drive structure is provided on the mounting cylinder, which sequentially drives multiple ejector connecting components to cooperate with the sewage conveying structure.

[0007] To further remove oily components from oily wastewater, the cyclone oil removal structure includes three cyclone cylinders arranged in a triangular pattern. Each cyclone cylinder has a cylindrical inlet section and a conical oil removal section. The conical oil removal section has a spiral flow channel and an outlet on one side. The cylindrical inlet section is connected to an inlet pipe on the side facing the wastewater conveying structure, and an oil discharge pipe is connected to the side end of the cylindrical inlet section.

[0008] To further remove residue from oily wastewater, two sloping diversion plates are fixedly connected longitudinally inside the slag removal box. Wastewater slag removal strips are provided on the slope surfaces of both sloping diversion plates. The top of the slag removal box is connected to a water inlet cylinder. The bottom end of the water inlet cylinder faces the upper side of the slope surface of the upper sloping diversion plate. A cleaning channel is connected between one end of the slag removal box and the mounting cylinder. A double-layer sealing plate is provided in the cleaning channel.

[0009] To further separate the residue from the oily wastewater, the wastewater slag removal bar is designed as a slope, with a concave collection groove on the wastewater slag removal bar, and multiple water passage grooves at the top of the wastewater slag removal bar.

[0010] To further transport the oily wastewater after slag removal, the wastewater transport structure includes a transport pump, a pumping pipe, an arc-shaped transport cylinder, and a water delivery sleeve. The transport pump is installed inside the installation cylinder, and its input end is connected to the pumping pipe, which extends into the bottom of the slag removal box. The arc-shaped transport cylinder is fixedly connected to the installation cylinder, and its output end is connected to the arc-shaped transport cylinder. Multiple water delivery sleeves are connected to the outer arc surface of the arc-shaped transport cylinder.

[0011] To further facilitate the transport of oily wastewater to the corresponding cyclone cylinder, the ejector connecting assembly includes a connecting cylinder, a closed cylinder seat, and a telescopic pipe. The connecting cylinder is fixedly connected inside the water supply sleeve. Multiple water passage holes are provided on the bottom circumference of the connecting cylinder. The closed cylinder seat is slidably disposed inside the connecting cylinder. The top of the closed cylinder seat is magnetically connected to the middle of the connecting cylinder. The top of the inlet pipe is connected to the telescopic pipe, and the top of the telescopic pipe is connected to a conical ejector cylinder. Multiple water inlet holes are provided on the top circumference of the conical ejector cylinder.

[0012] In order to synchronously drive the three conical ejector cylinders to rise and fall, a connecting frame is fixedly connected between the three corresponding conical ejector cylinders.

[0013] To drive the corresponding connecting frame to move longitudinally, the circumferential drive structure further includes an annular connecting cylinder and a drive electric cylinder. The annular connecting cylinder is fixedly connected to the mounting cylinder. The annular connecting cylinder is divided into a semi-circular narrow section and a semi-circular wide section. The semi-circular wide section is connected to the mounting cylinder. A rotating ring is rotatably connected between the semi-circular narrow section and the semi-circular wide section. A drive assembly is provided between the rotating ring and the mounting cylinder. The drive electric cylinder is located on one side of the rotating ring. The drive electric cylinder moves within the semi-circular wide section. The output end of the drive electric cylinder is magnetically connected to the connecting frame.

[0014] In order to discharge the separated oily components and wastewater separately, an arc-shaped water outlet cylinder and an arc-shaped oil outlet cylinder are fixedly connected to both sides of the mounting cylinder, respectively. The bottom of the arc-shaped water outlet cylinder and the arc-shaped oil outlet cylinder are connected to a discharge pipe. Multiple water outlets are connected to the arc-shaped water outlet cylinder, and multiple oil discharge pipes are connected to the arc-shaped oil outlet cylinder.

[0015] A method for treating oily wastewater includes the following steps: Step 1, Slag Removal: A small amount of oily wastewater is transported to the slag removal box for slag removal; Step 2, Conveying: After slag removal in the slag removal box, the oily wastewater is conveyed to the arc-shaped conveying cylinder using a conveying pump. The corresponding number of connecting frames are selected and driven to rise, causing the conical ejector cylinder to extend into the water conveying sleeve. This causes the closed cylinder seat to move, connecting the water passage and the water inlet, allowing the oily wastewater in the arc-shaped conveying cylinder to smoothly pass through the connecting cylinder and the conical ejector cylinder into the vortex cylinder. Step 3, Oil Removal: Oily wastewater is transported into the cyclone separator through the inlet pipeline. The thrust generated by the continuous transport of oily wastewater causes it to flow along the spiral channel. The oily components in the wastewater are separated from the wastewater under the action of centrifugal force and enter the central area of ​​the conical oil removal section. Finally, the oily components flow back to the cylindrical inlet section and are discharged through the oil drain pipe. The wastewater with the oily components removed is discharged through the outlet during the flow in the conical oil removal section. Step 4, Separation and Discharge: The wastewater separated inside the cyclone cylinder will enter the arc-shaped outlet cylinder through the outlet and be discharged through the discharge pipe on the corresponding side for further treatment. The separated oily components will be discharged through the oil discharge pipe into the arc-shaped oil discharge cylinder and then discharged through the discharge pipe on the corresponding side for further targeted treatment.

[0016] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, when a small amount of oily wastewater needs to be treated promptly, after the small amount of oily wastewater is removed by the slag removal box, the oily wastewater is transported to the arc-shaped conveying cylinder. Based on the amount of oily wastewater discharged, the corresponding number of connecting frames are selected to rise, causing the conical ejector cylinder to extend into the water conveying sleeve. This causes the closed cylinder seat to move, connecting the water inlet and the water outlet. This allows the oily wastewater in the arc-shaped conveying cylinder to smoothly pass through the connecting cylinder and the conical ejector cylinder into the vortex cylinder, separating the oily components from the wastewater. This reduces the number of vortex cylinders used, ensuring sufficient conveying capacity for the oily wastewater and guaranteeing that the oily wastewater undergoes sufficient separation through the vortex cylinder. This fully utilizes the principle of modular oil removal to match the actual amount of oily wastewater generated.

[0017] 2. In this invention, when separating oily wastewater, it is necessary to avoid the residue in the oily wastewater from entering the arc-shaped conveying cylinder and causing blockage in the subsequent cyclone cylinder. The oily wastewater is first conveyed to the slag removal box, so that the oily wastewater flows on the slope of the two sloped diversion plates. Through multiple wastewater slag removal strips, the removal of residue in the oily wastewater is ensured without affecting the normal conveying of the oily wastewater. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Example 1, as Figures 1 to 11 As shown, the present invention discloses an oily wastewater treatment device, including an installation cylinder 1, which is divided into a semi-circular cylinder and an arc-shaped cylinder. The semi-circular cylinder area is used to install a slag removal box 2, a conveying pump device 16, an arc-shaped conveying cylinder 18 and an arc-shaped oil outlet cylinder 33, and the arc-shaped cylinder area is used to install multiple swirl cylinders 3. like Figures 1 to 6 and Figure 9As shown, it also includes a cyclone oil removal structure 100. Multiple cyclone oil removal structures 100 are arranged in an arc shape within the mounting cylinder 1. Each cyclone oil removal structure 100 includes three cyclone cylinders 3 arranged in a triangular pattern. Each cyclone cylinder 3 has a cylindrical inlet section 4 and a conical oil removal section 5. The conical oil removal section 5 has a spiral flow channel 6 and an outlet 7 on one side. The cylindrical inlet section 4 is connected to an inlet pipe 8 on the side facing the sewage conveying structure 200, and an oil drain pipe 9 is connected to the side end of the cylindrical inlet section 4. When separating oily wastewater, the oily wastewater is transported into the cyclone cylinder 3 through the inlet pipe 8. The thrust generated by the continuous transport of oily wastewater causes it to flow rapidly within the cyclone cylinder 3. As the oily wastewater flows along the spiral channel 6, the oily components in the wastewater are separated from the wastewater under the action of centrifugal force and enter the central area of ​​the cone-shaped oil removal section 5. Finally, the oily components flow back to the cylindrical inlet section 4 and are discharged through the oil drain pipe 9. The wastewater with the oily components removed is discharged through the outlet 7 as it flows within the cone-shaped oil removal section 5.

[0028] Based on this embodiment, because the present invention allows multiple cyclone oil removal structures 100 to be used modularly, individually or in combination, only a small number of cyclone oil removal structures 100 are needed to handle a small amount of oily wastewater. Therefore, during the treatment of oily wastewater by individual or small numbers of cyclone oil removal structures 100, the remaining idle cyclone oil removal structures 100 can be kept clean and ready to cooperate in treating oily wastewater at any time. The present invention installs the cyclone oil removal structures 100 between the arc-shaped water outlet cylinder 32 and the arc-shaped oil outlet cylinder 33. Therefore, according to the usage requirements, a corresponding number of cyclone oil removal structures 100 can be selectively installed into the installation cylinder 1. After removing the arc-shaped oil outlet cylinder 33, the connection between the cyclone oil removal structure 100 and the corresponding component in the installation cylinder 1 is disconnected, and the cyclone oil removal structure 100 can be directly removed from the installation cylinder 1 by plugging and unplugging.

[0029] like Figures 1 to 8 and Figure 13As shown, a slag removal box 2 is fixedly connected to the top side of the installation cylinder 1. Oily wastewater passes through the slag removal box 2 to remove residual slag. Two sloping diversion plates 10 are fixedly connected longitudinally inside the slag removal box 2. Sewage slag removal strips 11 are provided on the slope surface of both sloping diversion plates 10. The top of the slag removal box 2 is connected to a water inlet cylinder 12, which is fixedly connected to the installation cylinder 1. The bottom end of the water inlet cylinder 12 faces the upper side of the slope surface of the upper sloping diversion plate 10. A cleaning channel connects one end of the slag removal box 2 to the installation cylinder 1. The cleaning channel is equipped with a double-layer sealing plate 13. The water inlet cylinder 12 is connected to a water inlet pipe. The bottom of the water inlet cylinder 12 is connected to multiple water outlets. Oily wastewater is transported into the water inlet cylinder 12 and discharged evenly into the slag removal box 2 through the multiple water outlets. It first flows on the slope at the top of the upper slope diversion plate 10, and then continues to flow into the slope at the top of the lower slope diversion plate 10 during the downward flow. The slag removal strips 11 set on the two slopes effectively remove the residue in the oily wastewater. When cleaning the residue on the slope and inside the sewage slag removal strip 11, the double-layer sealing plate 13 can be removed to allow the staff to clean the inside of the slag removal box 2. The double-layer sealing plate 13 can seal the cleaning channel connecting the slag removal box 2 and the installation cylinder 1. The wastewater sludge removal bar 11 is designed as a slope, and a concave collection trough 14 is provided on the wastewater sludge removal bar 11. Multiple water passage troughs 15 are provided at the top of the wastewater sludge removal bar 11. After the oily wastewater passes through the wastewater sludge removal bar 11, the oily wastewater will first flow through the concave collection trough 14. Through the internal design of the concave collection trough 14, the residue in the oily wastewater can be intercepted and stored. Then the oily wastewater continues to flow on the slope through the water passage troughs 15, while the residue is retained in the concave collection trough 14.

[0030] like Figures 1 to 5As shown, a wastewater conveying structure 200 is provided between the slag removal box 2 and multiple cyclone oil removal structures 100. The wastewater conveying structure 200 includes a conveying pump device 16, a pumping pipe 17, an arc-shaped conveying cylinder 18, and a water conveying sleeve 19. The conveying pump device 16 is installed inside the mounting cylinder 1, and the input end of the conveying pump device 16 is connected to the pumping pipe 17, which extends into the inner bottom of the slag removal box 2. The arc-shaped conveying cylinder 18 is fixedly connected inside the mounting cylinder 1, and the output end of the conveying pump device 16 is connected to the arc-shaped conveying cylinder 18. Multiple water conveying sleeves 19 are connected to the outer arc surface of the cylinder 18. The water pumping pipe 17 is arranged parallel to the bottom of the slag removal box 2. Multiple water pumping holes are opened on the water pumping pipe 17. When the conveying pump equipment 16 is started, the oily sewage in the slag removal box 2 is extracted through the water pumping pipe 17 and then conveyed to the arc-shaped conveying cylinder 18. The shape of the arc-shaped conveying cylinder 18 can optimize the internal volume of the arc-shaped conveying cylinder 18 while ensuring communication with multiple vortex cylinders 3, so that the oily sewage can maintain sufficient conveying power during the conveying process.

[0031] like Figures 1 to 7 and Figures 9 to 12 As shown, each cyclone oil removal structure 100 is connected to the sewage conveying structure 200 by an ejector connecting assembly 300, allowing the corresponding cyclone oil removal structure 100 to connect with the sewage conveying structure 200 for treating small amounts of oily sewage. The ejector connecting assembly 300 includes a connecting cylinder 20, a closed cylinder seat 22, and a telescopic pipe 23. The connecting cylinder 20 is fixedly connected inside the water conveying sleeve 19. Multiple water passage holes 21 are opened around the bottom circumference of the connecting cylinder 20. The closed cylinder seat 22 is slidably disposed inside the connecting cylinder 20. The top of the closed cylinder seat 22 is magnetically connected to the middle of the connecting cylinder 20. An iron ring 35 is fixedly fitted on the top of the closed cylinder seat 22. An electromagnet 36 is disposed in the middle of the connecting cylinder 20. The water conveying sleeve 19... An encapsulation protrusion 37 is provided inside the corresponding electromagnetic device 36 to protect the electromagnetic device 36. The ferromagnetic ring 35 is magnetically engaged with the electromagnetic device 36. The closed cylinder seat 22 is fitted inside the connecting cylinder 20. When it is not necessary for sewage to enter the connecting cylinder 20, the closed cylinder seat 22 is moved to the bottom of the connecting cylinder 20, so that the ferromagnetic ring 35 enters the magnetic connection area of ​​the electromagnetic device 36, and the ferromagnetic ring 35 is magnetically connected with the electromagnetic device 36, fixing the position inside the closed cylinder seat 22. The closed cylinder seat 22 is used to seal multiple water passages 21. When the electromagnetic device 36 is started, it can magnetically attract the ferromagnetic ring 35, which can guide the closed cylinder seat 22 to slide inside the connecting cylinder 20. The top of the inlet pipe 8 is connected to a telescopic pipe 23, and the top of the telescopic pipe 23 is connected to a conical ejector cylinder 24. The top circumference of the conical ejector cylinder 24 is provided with multiple water inlet holes 25, which drive the conical ejector cylinder 24 to rise. When the electromagnet device 36 stops magnetically connecting with the ferromagnetic ring 35, the top of the conical ejector cylinder 24 pushes the closed cylinder seat 22 to move inside the connecting cylinder 20, so that the multiple water inlet holes 25 and multiple water passage holes 21 correspond one-to-one and remain connected. The telescopic pipe 23 can adapt to the change in the distance between the inlet pipe 8 and the conical ejector cylinder 24. After the oily sewage enters the conical ejector cylinder 24 through the water inlet holes 25 and the water passage holes 21, the sewage then enters the vortex cylinder 3 through the telescopic pipe 23 and the inlet pipe 8. A connecting frame 26 is fixedly connected between the three corresponding conical ejector cylinders 24. A damping groove 38 is fixedly connected to the cyclone cylinder 3 in the middle of each cyclone oil removal structure 100. A damping slider is slidably connected in the damping groove 38. The damping slider is fixedly connected to the connecting frame 26, which drives the connecting frame 26 to move along the damping groove 38. This causes the connecting frame 26 to drive the three conical ejector cylinders 24 to move in the corresponding connecting cylinder 20, thereby controlling the flow of oily wastewater. By selecting the corresponding number of cyclone cylinders 3 to separate and treat oily wastewater, the continuous transport of oily wastewater can be guaranteed, and the actual treatment capacity of oily wastewater can be increased. The mounting cylinder 1 is provided with a circumferential drive structure 400 that sequentially drives multiple ejector connecting components 300 to cooperate with the sewage conveying structure 200. The circumferential drive structure 400 includes an annular connecting cylinder 27 and a drive electric cylinder 31. The annular connecting cylinder 27 is fixedly connected to the mounting cylinder 1. The annular connecting cylinder 27 is divided into a semi-circular narrow section 28 and a semi-circular wide section 29. The semi-circular wide section 29 is connected to the mounting cylinder 1. A rotating ring 30 is rotatably connected between the semi-circular narrow section 28 and the semi-circular wide section 29. A drive component is provided between the rotating ring 30 and the mounting cylinder 1. The drive electric cylinder 31 is located on one side of the rotating ring 30. The drive electric cylinder 31 moves within the semi-circular wide section 29. The output end of the drive electric cylinder 31 is magnetically connected to the connecting frame 26. The drive component drives the rotating ring 30 to rotate, causing the drive electric cylinder 31 to slide along the arc-shaped interior of the semi-circular wide section 29. The output end of the drive electric cylinder 31 is magnetically connected to the corresponding connecting frame 26, pushing the connecting frame 26 to slide on the damping groove 38. The drive assembly includes an internal gear section 39. The internal gear section 39 is provided on the inner arc surface of the rotating ring 30. A transmission gear 40 is meshed on the internal gear section 39. A motor drive device 41 and a gearbox 42 are provided on the mounting cylinder 1. The output end of the motor drive device 41 and the transmission gear 40 are both connected to the gearbox 42. When the motor drive device 41 is started, the transmission effect of the gearbox 42 drives the transmission gear 40 to rotate. Furthermore, through the transmission meshing relationship between the transmission gear 40 and the internal gear section 39, the rotating ring 30 is driven to rotate within the annular connecting cylinder 27. The rotating ring 30 will drive the drive electric cylinder 31 to reciprocate within the semi-circular wide section 29. A magnetic groove 43 is provided at the bottom of the connecting frame 26, and an electromagnet plug 44 is provided on the output end of the drive electric cylinder 31. The position of the drive electric cylinder 31 is moved to correspond to the position of the connecting frame 26, and the drive electric cylinder 31 is started, which drives the electromagnet plug 44 to be inserted into the magnetic groove 43, so that the electromagnet plug 44 is electrically connected to the magnetic groove 43, thereby realizing the reciprocating movement of the connecting frame 26.

[0032] Arc-shaped water outlet cylinder 32 and arc-shaped oil outlet cylinder 33 are fixedly connected to both sides of the mounting cylinder 1. The bottom of both arc-shaped water outlet cylinder 32 and arc-shaped oil outlet cylinder 33 are connected to discharge pipes 34. Multiple water outlets 7 are connected to arc-shaped water outlet cylinder 32, and multiple oil discharge pipes 9 are connected to arc-shaped oil outlet cylinder 33. Wastewater separated inside the vortex cylinder 3 enters the arc-shaped water outlet cylinder 32 through the water outlet 7 and is discharged through the discharge pipe 34 on the corresponding side for further treatment of the wastewater. The separated oily components are discharged into the arc-shaped oil outlet cylinder 33 through the oil discharge pipe 9 and then discharged through the discharge pipe 34 on the corresponding side for further targeted treatment of the oily components.

[0033] Based on this embodiment, when the cyclone cylinder 3 treats oily wastewater for a long time, oily impurities will adhere to the inside of the cyclone cylinder 3. In order to solve this problem, the present invention provides an ultrasonic transducer device 45 on the arc-shaped cylinder area where the cylinder 1 is installed. The output end of the ultrasonic transducer device 45 cooperates with the corresponding cyclone oil removal structure 100, so that the output end of the ultrasonic transducer device 45 contacts the outer wall of the cyclone cylinder 3. During the operation of the ultrasonic transducer device 45, the cyclone cylinder 3 generates high-frequency small-range vibration, thereby removing the oily components adhering to the inner wall of the cyclone cylinder 3.

[0034] The working principle of this oily wastewater treatment device: A small amount of oily wastewater is transported to the slag removal box 2. After slag removal in the slag removal box 2, the oily wastewater is transported to the arc-shaped conveying cylinder 18 using the conveying pump device 16. Based on the amount of oily wastewater discharged, a corresponding number of swirl cylinders 3 are selected to drive the rotating ring 30 to rotate within the annular connecting cylinder 27. The rotating ring 30 drives the drive electric cylinder 31 to reciprocate within the semi-circular wide section 29, moving the position of the drive electric cylinder 31 to correspond with the position of the corresponding connecting frame 26. Start the drive electric cylinder 31, which drives the electromagnet plug 44 to be inserted into the magnetic groove 43, so that the electromagnet plug 44 is electrically connected to the magnetic groove 43. Continue to start the drive electric cylinder 31 to drive the connecting frame 26 to rise, which drives the conical ejector cylinder 24 to extend into the water conveying sleeve 19, and drives the closed cylinder seat 22 to move, so that the water passage hole 21 and the water inlet hole 25 are connected, so that the oily sewage in the arc-shaped conveying cylinder 18 can smoothly pass through the connecting cylinder 20 and the conical ejector cylinder 24 into the vortex cylinder 3; Oily wastewater is transported into the vortex cylinder 3 via the inlet pipe 8. The thrust generated by the continuous transport of oily wastewater causes it to flow rapidly within the vortex cylinder 3. As the oily wastewater flows along the spiral channel 6, the oily components are separated from the wastewater under the action of centrifugal force and enter the central area of ​​the cone-shaped oil removal section 5. Finally, the oily components flow back to the cylindrical inlet section 4 and are discharged through the oil drain pipe 9. The wastewater with the oily components removed is discharged through the outlet 7 during its flow within the cone-shaped oil removal section 5, thus separating the oily components from the wastewater.

[0035] Example 2: Based on an oily wastewater treatment device, the present invention also proposes an oily wastewater treatment method, specifically including the following steps: Step 1, Slag Removal: A small amount of oily wastewater is transported to the slag removal box 2 for slag removal; Step 2, Conveying: After slag removal in the slag removal box 2, the oily wastewater is conveyed to the arc-shaped conveying cylinder 18 using the conveying pump equipment 16. The corresponding number of connecting frames 26 are selected to rise, which drives the conical ejector cylinder 24 to extend into the water conveying sleeve 19. This causes the closed cylinder seat 22 to move, connecting the water passage hole 21 and the water inlet hole 25, allowing the oily wastewater in the arc-shaped conveying cylinder 18 to smoothly pass through the connecting cylinder 20 and the conical ejector cylinder 24 into the vortex cylinder 3. Step 3, oil removal: The oily wastewater is transported to the vortex cylinder 3 through the inlet pipe 8. The oily wastewater will flow along the spiral channel 6 due to the thrust generated by the continuous transport of the oily wastewater. The oily components in the wastewater are separated from the wastewater under the action of centrifugal force and enter the central area of ​​the cone-shaped oil removal section 5. Finally, the oily components flow back to the cylindrical inlet section 4 and are discharged through the oil drain pipe 9. The wastewater with the oily components removed is discharged through the outlet 7 during the flow in the cone-shaped oil removal section 5. Step 4, Separation and Discharge: The wastewater separated inside the swirl cylinder 3 will enter the arc-shaped outlet cylinder 32 through the outlet 7 and be discharged through the discharge pipe 34 on the corresponding side for further treatment. The separated oily components will be discharged through the oil discharge pipe 9 into the arc-shaped oil outlet cylinder 33 and then discharged through the discharge pipe 34 on the corresponding side for further targeted treatment.
