Description

Technical Field

[0001] The present invention relates to the technical field of oil fume purification, and in particular to an industrial oil fume purifier and a method thereof. Background Art

[0002] The oil fume generated by industrial manufacturing is a major source of pollution and needs to be purified to remove oil stains and other particulate impurities in the oil fume and ensure that the particulate matter content in the emitted oil fume reaches the standard emission content. The industrial oil fume purifier is an essential equipment for purifying oil fume.

[0003] At present, most industrial oil fume purifiers adopt physical filtration, filtering and purifying oil stains and particulate matter in oil fume through filter screens and filters. For example, the announcement number CN117959837A discloses an oil fume purification filter device and an oil fume purification filter system, which includes a shell defining an ascending oil fume channel, a primary filter layer group and a secondary filter located in the shell; the primary filter layer group is rotatably connected to the shell and is equipped with a driver for driving it to rotate; it also includes a detector and a controller, the detector is used to detect the amount of oil accumulated in the primary filter layer group, and the controller is used to control the driver to rotate and adjust the primary filter layer group according to the detection result of the detector; the shell is provided with an oil discharge mechanism, which is used to discharge the oil on the primary filter layer group out of the shell when the primary filter layer group is in a tilted state. The present invention also discloses an oil fume purification filter system having the oil fume purification filter device.

[0004] The oil fume purification filter device can discharge oil in time to avoid cleaning difficulties and safety hazards caused by oil droplets dripping downwards. However, when the oil fume purification filter device is used, a filtering method is used to extract oil stains in the oil fume and the extracted oil stains are exported. Since the filtering method is always prone to clogging, the filter screen that plays a filtering role needs to be replaced or cleaned regularly, which affects the normal discharge of oil fume. At the same time, the filtering effect of the filter screen is poor, and particulate impurities with a particle size smaller than the filter screen cannot be effectively purified.

[0015] The mixing part includes a cylinder rotatably mounted on a liquid retaining ring through a sealing ring, two liquid retaining plates are fixedly mounted on the cylinder, the two liquid retaining plates and the cylinder divide the space between the liquid retaining ring and the bottom shell into two liquid inlet spaces, a liquid guide cylinder is rotatably mounted on the cylinder, the liquid guide cylinder is fixedly connected to the centrifugal cylinder, a flow guide cylinder is fixedly connected to the liquid guide cylinder, and a stirring mechanism is mounted on the flow guide cylinder;

[0016] The stirring mechanism comprises a baffle plate fixedly mounted on the guide tube, the baffle plate adopts an inclined annular design, a fixed ring is fixedly mounted on the baffle plate, a movable ring is fixedly mounted on the fixed ring by connecting a telescopic ring, the movable ring and the guide tube are sealed and slidably connected, a liquid inlet hole matching the movable ring is provided on the guide tube, a plurality of connecting pipes are fixedly connected on the fixed ring, each of the connecting pipes is fixedly connected with a stirring box, and a flow control structure is installed in each of the connecting pipes;

[0017] The flow control structure includes a fixed ring fixedly installed in the connecting pipe, a plurality of fixed blocks are fixedly installed on the fixed ring, a pressure spring is fixedly installed on each of the fixed blocks, and a sealing plate matching the fixed ring is fixedly installed on the plurality of pressure springs.

[0018] Preferably, a column is fixedly mounted on the centrifugal cylinder, a liquid separation plate is fixedly mounted on the column, and the liquid separation plate is close to the lower end of the centrifugal cylinder.

[0019] The present invention also provides an industrial fume purification method, which is characterized by comprising the above industrial fume purifier and further comprising the following steps:

[0020] S1. First, the oil smoke is introduced into the bottom shell through the oil smoke introduction pipe, and the cleaning liquid is introduced into the bottom shell through the liquid inlet pipe. Under the action of the baffle ring, the smoke will enter the air inlet box, and the cleaning liquid will enter the liquid inlet box. The oil smoke in the air inlet box will enter the liquid baffle ring through the holes on the air inlet box under the action of the pressure injected from the outside, and the cleaning liquid in the liquid inlet box will enter the liquid baffle ring through the holes on the liquid inlet box under the action of the external pressure and its own gravity. They are mixed in the liquid baffle ring. Since the weight of the oil smoke is less than the weight of the cleaning liquid, the oil smoke will move upward and the cleaning liquid will move downward during mixing, forming a hedge in the liquid baffle ring. After the hedge is completed, the oil stains and impurities in the oil smoke will be absorbed by the cleaning liquid, and the gas in the oil smoke will be discharged through the one-way pipe, which is connected to the discharge pipe and discharged to a specific area.

[0021] S2, then start the motor, the motor drive end rotates to drive the liquid separation cylinder to rotate, and then drives the centrifugal cylinder to rotate through the liquid guide tube, the centrifugal cylinder drives the liquid guide cylinder to rotate, thereby driving the guide cylinder to rotate, the guide cylinder rotates to drive the fixed ring on the guide cylinder to rotate, and during the rotation of the fixed ring, the connecting pipe and the stirring box on the fixed ring will be driven to rotate, so as to stir and mix the mixed cleaning liquid and oil impurities in the liquid retaining ring;

[0022] During the mixing process, the speed of the motor drive end is controlled. During mixing, the speed of the motor drive end is low. At this time, the mixture of cleaning liquid and oil impurities in the liquid retaining ring will produce a pressing force on the sealing plate under the rotation of the stirring box. At this time, the pressing force is smaller than the total elastic force of multiple pressing springs. At this time, when the stirring box rotates and stirs, the sealing plate cannot be separated from the fixed ring, so the mixed liquid cannot enter the fixed ring through the connecting pipe. This process only plays a stirring role.

[0023] S3. When the stirring reaches a certain time, the speed of the motor driving end is controlled so that the pressing force between the mixed liquid and the sealing plate is greater than the total elastic force of the multiple pressing springs. At this time, the mixed liquid will enter the fixed ring through the connecting pipe. Under the action of the baffle plate, the mixed liquid will impact upward in the fixed ring. The impact force will cause the moving ring to move upward on the guide tube, but the speed at this time cannot move the moving ring to separate from the hole, and the liquid inlet hole on the guide tube is still blocked. Therefore, the mixed liquid cannot enter the guide tube. The adjustment of the speed of the motor driving end can change the impact force of the mixed liquid on the moving ring, so that the moving ring will move up and down repeatedly on the guide tube. The movement will drive the connecting telescopic ring to expand and contract, and the expansion and contraction will cause the connecting telescopic ring to vibrate laterally, thereby generating a transverse vibration wave. The transverse vibration wave will vibrate and mix the mixed liquid in the fixed ring, shake off the dust coated on the oil stain, and separate the oil stain from the dust.

[0024] S4, then change the speed of the motor drive end, at this time, the impact force of the mixed liquid can drive the moving ring to move to the top, at this time the moving ring is separated from the liquid inlet hole on the guide tube, at this time the mixed liquid in the fixed ring will enter the guide tube, because the liquid guide tube on the guide tube adopts an inclined design, so under the action of the centrifugal force generated by the rotation of the motor drive end, the mixed liquid will enter the centrifugal tube along the liquid guide tube, and the mixed liquid will be preliminarily dispersed, and the mixed liquid will be close to the inner wall of the centrifugal tube;

[0025] S5. Under the action of centrifugal force, the heavier particles in the mixed liquid will produce a larger centrifugal force, and the lighter particles will be subjected to a smaller centrifugal force, so they will be separated from the light and heavy particles on the inner wall of the centrifuge cylinder. The heavier particle mixed liquid will overflow from the top of the centrifuge cylinder along the inner wall of the centrifuge cylinder through the liquid guide channel and enter the upper chamber of the liquid outlet cover, while the lighter particle mixed liquid will enter the liquid separator cylinder and enter the lower chamber on the liquid outlet cover through the liquid guide tube on the liquid separator cylinder. Then the two mixed liquids with different weights after the reaction will pass through the oil outlet pipe and the liquid outlet pipe and flow out from the liquid outlet pipe and the oil outlet pipe.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1: During the specific use of this device, a counter-cleaning method is used to perform a scrubbing operation on the oil fume, so as to remove the particulate impurities in the oil fume. The contact surface between the oil fume and the cleaning liquid is wider. In the same time period, the particulate matter in the oil fume is removed faster, the cleaning efficiency is improved, and it is less affected by the external input pressure.

[0028] 2: During the specific use of this device, closed stirring and mixing is adopted, which can make the oil stains separated from the oil smoke and the cleaning liquid mixture quickly mixed in the equipment, so that the oil stains and other particulate matter can contact with the cleaning liquid more fully and evenly, so as to achieve the purpose of more thorough cleaning, and can effectively reduce and improve the separation efficiency of the oil stains.

[0029] 3: During the specific use of the device, during the stirring and mixing process, the expansion and contraction of the connecting telescopic ring generates lateral vibration waves, and the movement speed of the ions is increased by the lateral vibration generated by the connecting telescopic ring and the vertical vibration generated by the speed change, thereby achieving the purpose of improving the mixing and cleaning efficiency.

[0030] 4: During the specific use of this device, it has the advantages of multi-stage adjustment and multiple mixing methods, which can not only make the oil stain separation efficiency higher and the oil stain separation more thorough, but also reduce the probability of the oil stain being mixed with the cleaning liquid again after separation through the separate liquid separator and centrifugal cylinder, and reduce the content of impurities in the oil stain after separation.

[0031] To sum up, the present invention removes particulate matter such as dust and oil stains in oil fume by means of air washing, has a better purification effect, and removes oil stains and other particulate matter in oil fume more thoroughly. At the same time, the oil stains in oil fume can be separated from other particulate matter, and the oil stains can be recovered, thereby realizing waste utilization, improving energy utilization rate, and no cleaning is required, which is convenient to operate.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Reference Figure 1-Figure 6 An industrial oil fume purifier includes a liquid outlet cover 10 fixedly installed in a shell 1, the upper part of the shell 1 is open, and the upper end of the shell 1 is flush with the upper end of the liquid outlet cover 10, and also includes a centrifugal part, the centrifugal part includes a motor 2 fixedly installed on the liquid outlet cover 10, the liquid outlet cover 10 is composed of two upper and lower chambers, a centrifugal cylinder 12 is rotatably installed on the liquid outlet cover 10, and a liquid separation mechanism matched with the two chambers is installed in the centrifugal cylinder 12; a column is fixedly installed on the centrifugal cylinder 12, and a liquid separation plate 15 is fixedly installed on the column, and the liquid separation plate 15 is close to the lower end of the centrifugal cylinder 12;

[0055] The function of the liquid separator 15 is to disperse the mixed liquid entering the centrifugal cylinder 12, so that the mixed liquid has a tendency to move toward the inner wall of the centrifugal cylinder 12 when entering the centrifugal cylinder 12, which can reduce the accumulation of the mixed liquid below the centrifugal cylinder 12, thereby reducing the total weight of the centrifugal cylinder 12 and the centrifugal mixed liquid. Under the same speed, the heavier the weight, the greater the torque required to be provided by the driving end of the motor 2. Reducing the weight can reduce the torque on the driving end of the motor 2, thereby achieving the purpose of reducing energy consumption and extending the service life of the motor 2.

[0056] Reference Figure 1-Figure 6The liquid separation mechanism includes a liquid separation cylinder 13 fixedly installed in the centrifugal cylinder 12, the liquid separation cylinder 13 is connected to the centrifugal cylinder 12 through a liquid guide tube 14, and a liquid guide channel is reserved between the liquid separation cylinder 13 and the centrifugal cylinder 12, the liquid guide tube 14 penetrates the centrifugal cylinder 12 and the liquid separation cylinder 13 (completely penetrates), and the liquid guide tube 14 extends into the lower chamber in the liquid outlet cover 10, the driving end of the motor 2 is fixedly connected to the liquid separation cylinder 13, and a liquid outlet structure is installed on the liquid outlet cover 10;

[0057] The liquid outlet cover 10 and the centrifugal cylinder 12 are sealed and rotatably connected to improve the sealing effect of the two. The function of the liquid guide channel is to make the oil stain separation more efficient and more thorough. The separate liquid separator 13 and the centrifugal cylinder 12 can also reduce the probability of the oil stain being mixed with the cleaning liquid again after separation, thereby reducing the content of impurities in the oil stain after separation.

[0058] Reference Figure 2-Figure 3 , Figure 6 The liquid outlet structure includes a liquid outlet pipe 7 and an oil outlet pipe 8 fixedly mounted on the liquid outlet cover 10. The liquid outlet pipe 7 is connected to the upper chamber of the liquid outlet cover 10, and the oil outlet pipe 8 is connected to the lower chamber of the liquid outlet cover 10. The liquid outlet pipe 7 is fixedly connected to the oil outlet pipeline 3, and the oil outlet pipe 8 is fixedly connected to the liquid outlet pipeline 4;

[0059] The main function of this part is to output and transfer the mixed liquid. The oil outlet pipe 8 and the liquid outlet pipe 7 adopt a ring design, which can output the replacement liquid to the greatest extent and reduce the residual amount of the mixed liquid in the liquid outlet cover 10.

[0060] Reference Figure 1-Figure 2 , Figure 7-12 , the liquid inlet part includes a bottom shell 5 fixedly mounted on the liquid outlet cover 10 through a connecting rod 11, a sealing plate 16 is fixedly mounted on the bottom shell 5, a fume introduction pipe 6 and a liquid inlet pipe 17 are fixedly connected to the bottom shell 5, a liquid retaining ring 20 is fixedly mounted in the bottom shell 5 through a support rod, a mixing and hedging mechanism is installed in the liquid retaining ring 20, and a plurality of one-way pipes are fixedly connected to the liquid retaining ring 20, each of which penetrates and extends out of the bottom shell 5;

[0061] The function of the sealing plate 16 is to seal the connection between the centrifugal cylinder 12 and the bottom shell 5, which can effectively prevent the mixed liquid in the bottom shell 5 from leaking from the connection between the bottom shell 5 and the centrifugal cylinder 12, thereby improving the airtightness of the centrifugal separation operation.

[0062] The mixing and hedging mechanism includes an air inlet box 22 and a liquid inlet box 27 fixedly installed in the liquid retaining ring 20. The air inlet box 22 is provided with an air inlet, and the liquid inlet box 27 is provided with a liquid inlet, and the opening directions of the air inlet and the liquid inlet are opposite;

[0063] The air inlet box 22 is located at the bottom of the liquid retaining ring 20, and the liquid inlet box 27 is located at the top of the liquid retaining ring 20. The upper part of the air inlet box 22 and the bottom of the liquid inlet box 27 are provided with a plurality of holes, and a one-way tube is fixedly installed in each hole;

[0064] The function of this part is to make the cleaning liquid and the oil smoke produce convection in the liquid retaining ring 20. During the convection, the cleaning liquid and the oil smoke will pass through each other, increasing the contact area between the cleaning liquid and the oil smoke. The contact can cause a scrubbing reaction, thereby improving the scrubbing efficiency.

[0065] Reference Fig.10 A sealing disk 9 is rotatably mounted on the air inlet box 22, and the sealing disk 9 is fixedly connected to the guide tube 23;

[0066] The function of the sealing disk 9 is to dock with the guide tube 23 to avoid leakage. At the same time, the air inlet box 22 can also be divided to form an annular cavity in the air inlet box 22, so that the oil smoke in the air inlet box 22 can only enter the liquid retaining ring 20 through the hole, reducing the space in the air inlet box 22 and making the external pressure required for the oil smoke to enter the liquid retaining ring 20 smaller.

[0067] Reference Figure 10-12 Two baffle rings 21 are fixedly installed in the bottom shell 5. Both baffle rings 21 are semicircular in design, and both ends of the two baffle rings 21 are fixed to the liquid baffle plate. The two baffle rings 21 are respectively located in the middle and bottom of the bottom shell 5;

[0068] The function of the middle baffle ring 21 is to limit the cleaning liquid in the liquid baffle ring 20, prevent the cleaning liquid from entering the bottom of the liquid baffle ring 20, and ensure that the cleaning liquid enters the liquid inlet box 27 smoothly. The function of the lower baffle ring 21 is to limit the oil smoke in the liquid baffle ring 20, prevent the oil smoke from entering the bottom of the liquid baffle ring 20 and unable to enter the air inlet box 22, ensure that the oil smoke completely enters the air inlet box 22 and ensure that the cleaning liquid completely enters the liquid inlet box 27, and avoid oil smoke and cleaning liquid remaining in the liquid baffle ring 20.

[0069] Reference Figure 10-12 , a mixing part, which includes a cylinder 18 rotatably mounted on a liquid retaining ring 20 through a sealing ring 26, two liquid retaining plates fixedly mounted on the cylinder 18, the two liquid retaining plates and the cylinder 18 divide the space between the liquid retaining ring 20 and the bottom shell 5 into two symmetrical spaces on the left and right, a liquid guiding cylinder 19 rotatably mounted on the cylinder 18, the liquid guiding cylinder 19 is fixedly connected to the centrifugal cylinder 12, a flow guiding cylinder 23 is fixedly connected to the liquid guiding cylinder 19, and a stirring mechanism is mounted on the flow guiding cylinder 23; a blocking ring is fixedly mounted between the cylinder 18 and the sealing plate 16, so as to prevent the oil smoke and cleaning liquid in the bottom shell 5 from entering the sealing plate 16.

[0070] refer to Fig.11The liquid retaining plate is used to divide the space between the liquid retaining ring 20 and the bottom shell 5 into two symmetrical spaces on the left and right. The oil smoke enters the left space, and the cleaning liquid enters the right space, thereby realizing the separation of the mixed liquid and ensuring that the oil smoke can only enter the liquid retaining ring 20 through the air inlet box 22, and the cleaning liquid can only enter the liquid retaining ring 20 through the liquid inlet box 27. This can ensure convection and improve the mixing efficiency.

[0071] Reference Figure 10-Figure 15 The stirring mechanism includes a baffle plate 31 fixedly mounted on the guide tube 23. The baffle plate 31 adopts an inclined ring design. A fixed ring 25 is fixedly mounted on the baffle plate 31. A movable ring 24 is fixedly mounted on the fixed ring 25 by connecting the telescopic ring 30. The movable ring 24 and the guide tube 23 are sealed and slidably connected. The guide tube 23 is provided with a liquid inlet hole matched with the movable ring 24. A plurality of connecting pipes 28 are fixedly connected to the fixed ring 25. A stirring box 29 is fixedly connected to each connecting pipe 28. A flow control structure is installed in each connecting pipe 28.

[0072] The baffle plate 31 is designed with an inclined ring so that the mixed liquid entering the fixed ring 25 has a tendency to move upward, requiring a smaller centrifugal force, and also preventing the mixed liquid from remaining in the fixed ring 25;

[0073] The function of the connecting telescopic ring 30 is to connect the fixed ring 25 and the movable ring 24, so that the fixed ring 25, the connecting telescopic ring 30 and the movable ring 24 form a closed cavity, ensuring that the mixed liquid can only flow in the cavity. At the same time, the connecting telescopic ring 30 will generate transverse waves during the expansion and contraction process, which can vibrate the mixed liquid in the cavity and improve the mixing efficiency. At the same time, it can also cause the two-phase mixed liquid after mixing to produce preliminary vibration stratification, thereby accelerating the separation efficiency of the mixed liquid.

[0074] Reference Figure 16-Figure 19 The flow control structure includes a fixed ring 32 fixedly installed in the connecting pipe 28, a plurality of fixed blocks 33 are fixedly installed on the fixed ring 32, a pressure spring 35 is fixedly installed on each fixed block 33, and a blocking plate 34 matched with the fixed ring 32 is fixedly installed on the plurality of pressure springs 35;

[0075] By controlling the rotation speed of the driving end of the motor 2 to control the pressing force between the mixed liquid and the sealing plate 34, the clutch between the sealing plate 34 and the fixed ring 32 is realized. The stirring and conveying of the mixed liquid can be switched freely without adding a control valve, which is more convenient to use. At the same time, it can also avoid the occurrence of bubbles in the mixed liquid due to excessive stirring speed.

[0076] The specific usage of this device is as follows:

[0077] S1. First, the oil smoke is introduced into the bottom shell 5 through the oil smoke introduction pipe 6, and the cleaning liquid is introduced into the bottom shell 5 through the liquid inlet pipe 17. Under the action of the baffle ring 21, the smoke will enter the air inlet box 22, and the cleaning liquid will enter the liquid inlet box 27. The oil smoke in the air inlet box 22 will enter the liquid baffle ring 20 through the holes on the air inlet box 22 under the action of the pressure injected from the outside, and the cleaning liquid in the liquid inlet box 27 will enter the liquid baffle ring 20 through the holes on the liquid inlet box 27 under the action of the external pressure and its own gravity, and mix in the liquid baffle ring 20. Since the weight of the oil smoke is less than the weight of the cleaning liquid, the oil smoke will move upward and the cleaning liquid will move downward during mixing, forming a hedge in the liquid baffle ring 20. After the hedge is completed, the oil stains and impurities in the oil smoke will be absorbed by the cleaning liquid, and the gas in the oil smoke will be discharged through the one-way pipe, which is connected to the discharge pipe and discharged to a specific area.

[0078] S2, then start the motor 2, the driving end of the motor 2 rotates to drive the liquid separation cylinder 13 to rotate, and then drives the centrifugal cylinder 12 to rotate through the liquid guide tube 14, the centrifugal cylinder 12 drives the liquid guide cylinder 19 to rotate, thereby driving the guide cylinder 23 to rotate, and the rotation of the guide cylinder 23 drives the fixed ring 25 on the guide cylinder 23 to rotate, and during the rotation of the fixed ring 25, the connecting pipe 28 and the stirring box 29 on the fixed ring 25 are driven to rotate, so as to stir and mix the mixed cleaning liquid and oil impurities in the liquid retaining ring 20;

[0079] During the mixing process, the speed of the driving end of the motor 2 is controlled. During the mixing process, the speed of the driving end of the motor 2 is low. At this time, the mixture of the cleaning liquid and the oily impurities in the liquid retaining ring 20 will produce a pressing force on the blocking plate 34 under the rotation of the stirring box 29. At this time, the pressing force is less than the total elastic force of the multiple pressing springs 35. At this time, when the stirring box 29 rotates for stirring, the blocking plate 34 cannot be separated from the fixing ring 32. Therefore, the mixed liquid cannot enter the fixing ring 25 through the connecting pipe 28. This process only plays a stirring role.

[0080] S3. When the stirring reaches a certain time, the speed of the driving end of the motor 2 is controlled so that the pressing force between the mixed liquid and the sealing plate 34 is greater than the total elastic force of the multiple pressing springs 35. At this time, the mixed liquid will enter the fixed ring 25 through the connecting pipe 28. Under the action of the baffle plate 31, the mixed liquid will impact upward in the fixed ring 25. The impact force will cause the movable ring 24 to move upward on the guide tube 23, but the speed at this time cannot move the movable ring 24 to separate from the hole, and the liquid inlet hole on the guide tube 23 is still blocked. Therefore, the mixed liquid cannot enter the guide tube 23. The adjustment of the speed of the driving end of the motor 2 can change the impact force of the mixed liquid on the movable ring 24, so that the movable ring 24 will move up and down repeatedly on the guide tube 23. The movement will drive the connecting telescopic ring 30 to expand and contract, and the expansion and contraction will cause the connecting telescopic ring 30 to generate lateral vibration, thereby generating lateral vibration waves. The lateral vibration waves will vibrate and mix the mixed liquid in the fixed ring 25, shake off the dust coated on the oil stain, and separate the oil stain from the dust.

[0081] S4, then change the speed of the driving end of the motor 2, and at this time, the moving ring 24 can be driven to move to the top by the impact force of the mixed liquid. At this time, the moving ring 24 is separated from the liquid inlet hole on the guide tube 23, and the mixed liquid in the fixed ring 25 will enter the guide tube 23. Since the liquid guide tube 19 on the guide tube 23 adopts an inclined design, the mixed liquid will enter the centrifugal tube 12 along the liquid guide tube 19 under the action of the centrifugal force generated by the rotation of the driving end of the motor 2. Under the action of the liquid separation plate 15, the mixed liquid will be preliminarily dispersed and the mixed liquid will be close to the inner wall of the centrifugal tube 12;

[0082] S5. Under the action of centrifugal force, the heavier particles in the mixed liquid will generate a larger centrifugal force, and the lighter particles will be subjected to a smaller centrifugal force, so they will be separated from the light and heavy particles on the inner wall of the centrifuge cylinder 12. The heavier particle mixed liquid will overflow from the top of the centrifuge cylinder 12 along the inner wall of the centrifuge cylinder 12 through the liquid guide channel and enter the upper chamber of the liquid outlet cover 10, while the lighter particle mixed liquid will enter the liquid separator 13 and enter the lower chamber on the liquid outlet cover 10 through the liquid guide tube 14 on the liquid separator 13. Then, the two mixed liquids with different weights after the reaction will pass through the oil outlet pipe 8 and the liquid outlet pipe 7 and flow out from the liquid outlet pipe 4 and the oil outlet pipe 3 (the ion weight of the oil stain is less than the ion weight of water and other particulate impurities).

[0083] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The industrial fume purifier according to claim 1, characterized in that: A column is fixedly mounted on the centrifugal cylinder (12), and a liquid separation plate (15) is fixedly mounted on the column, wherein the liquid separation plate (15) is close to the lower end of the centrifugal cylinder (12).

3. An industrial fume purification method, used for the industrial fume purifier according to any one of claims 1-2, characterized in that: The following steps are involved: S1. First, the oil smoke is introduced into the bottom shell (5) through the oil smoke introduction pipe (6), and the cleaning liquid is introduced into the bottom shell (5) through the liquid inlet pipe (17). Under the action of the baffle ring (21), the smoke will enter the air inlet box (22), and the cleaning liquid will enter the liquid inlet box (27). Under the action of the external pressure, the oil smoke in the air inlet box (22) will enter the liquid baffle ring (20) through the hole on the air inlet box (22), and the cleaning liquid in the liquid inlet box (27) will enter the liquid baffle ring (20) under the external pressure. Under the action of the oil fume force and its own gravity, the oil fume enters the liquid retaining ring (20) through the hole on the liquid inlet box (27) and mixes in the liquid retaining ring (20). Since the weight of the oil fume is less than the weight of the cleaning liquid, when mixing, the oil fume moves upward and the cleaning liquid moves downward, forming a counter-attack in the liquid retaining ring (20). After the counter-attack is completed, the oil stains and impurities in the oil fume are absorbed by the cleaning liquid, and the gas in the oil fume is discharged through the one-way pipe, connected to the discharge pipe on the one-way pipe, and discharged to a specific area. S2, then the motor (2) is turned on, the driving end of the motor (2) rotates to drive the liquid separation cylinder (13) to rotate, and then drives the centrifugal cylinder (12) to rotate through the liquid guide tube (14), the centrifugal cylinder (12) drives the liquid guide cylinder (19) to rotate, thereby driving the guide cylinder (23) to rotate, and the rotation of the guide cylinder (23) drives the fixed ring (25) on the guide cylinder (23) to rotate, and during the rotation of the fixed ring (25), the connecting pipe (28) and the stirring box (29) on the fixed ring (25) are driven to rotate, so as to stir and mix the mixed cleaning liquid and the oil stain impurities in the liquid retaining ring (20); During the mixing process, the rotation speed of the driving end of the motor (2) is controlled. During the mixing process, the rotation speed of the driving end of the motor (2) is low. At this time, the mixture of the cleaning liquid and the oily impurities in the liquid retaining ring (20) will generate a pressing force on the sealing plate (34) under the rotation of the stirring box (29). At this time, the pressing force is smaller than the total elastic force of the plurality of pressing springs (35). At this time, when the stirring box (29) rotates for stirring, the sealing plate (34) cannot be separated from the fixing ring (32). Therefore, the mixed liquid cannot enter the fixing ring (25) through the connecting pipe (28). This process only plays a stirring role. S3. After stirring for a certain period of time, the rotation speed of the driving end of the motor (2) is controlled so that the compressive force between the mixed liquid and the blocking plate (34) is greater than the total elastic force of the plurality of compressive springs (35). At this time, the mixed liquid enters the fixed ring (25) through the connecting pipe (28). Under the action of the baffle plate (31), the mixed liquid is impacted upward in the fixed ring (25). The impact force causes the movable ring (24) to move upward on the guide tube (23). However, the rotation speed at this time cannot cause the movable ring (24) to move to separate from the hole, and the guide tube (23) is still impacted. The liquid inlet hole on the guide tube (23) is blocked, so that the mixed liquid cannot enter the guide tube (23). The speed of the driving end of the motor (2) is adjusted to change the impact force of the mixed liquid on the movable ring (24), so that the movable ring (24) is repeatedly moved up and down on the guide tube (23). The movement drives the connecting telescopic ring (30) to expand and contract. The expansion and contraction causes the connecting telescopic ring (30) to vibrate laterally, thereby generating a transverse vibration wave. The transverse vibration wave vibrates and mixes the mixed liquid in the fixed ring (25), shakes off the dust coated on the oil stain, and separates the oil stain from the dust. S4, then changing the rotation speed of the driving end of the motor (2), the impact force of the mixed liquid can drive the movable ring (24) to move to the top, the movable ring (24) is separated from the liquid inlet hole on the guide tube (23), and the mixed liquid in the fixed ring (25) enters the guide tube (23). Since the liquid guide tube (19) on the guide tube (23) adopts an inclined design, the centrifugal force generated by the rotation of the driving end of the motor (2) causes the mixed liquid to enter the centrifugal tube (12) along the liquid guide tube (19), and the mixed liquid is initially dispersed, so that the mixed liquid is pressed against the inner wall of the centrifugal tube (12); S5. Under the action of centrifugal force, the heavier particles in the mixed liquid will generate a larger centrifugal force, while the lighter particles will be subjected to a smaller centrifugal force, and thus will be separated from the light and heavy particles on the inner wall of the centrifuge cylinder (12). The heavier particle mixed liquid will flow along the inner wall of the centrifuge cylinder (12) through the liquid guide channel and overflow from the top of the centrifuge cylinder (12) into the upper chamber of the liquid outlet cover (10), while the lighter particle mixed liquid will enter the liquid separator cylinder (13) and enter the lower chamber of the liquid outlet cover (10) through the liquid guide tube (14) on the liquid separator cylinder (13). Then, the two mixed liquids with different weights after the reaction will flow out from the liquid outlet pipe (4) and the oil outlet pipe (3) through the oil outlet pipe (8) and the liquid outlet pipe (7).
