Description

Technical Field

[0001] This utility model belongs to the field of oil fume treatment technology, and in particular relates to a high-efficiency oil fume purification device. Background Technology

[0002] Traditional fume purification equipment generally suffers from problems such as low purification efficiency, high maintenance difficulty, and high energy consumption. The impact of low-efficiency fume emissions on the environment and human health is becoming increasingly serious, especially in the catering industry and industrial production. For example, Chinese patent application number CN201910936308.X discloses an oil fume purification device, including a range hood body, a horizontal blowing device located below the range hood body, and an air curtain device located on the stove platform; the range hood body is used to draw oil fumes generated on the stove platform into the range hood body; the horizontal blowing device is used to generate a horizontal rotating airflow; the air curtain device is used to generate an air curtain that moves from the stove platform toward the range hood body and converges inward; wherein, the air curtain generated by the air curtain device envelops the horizontal rotating airflow. However, the disadvantage of this technical solution is that the device does not have a sound wave gathering function and a spray function, nor does it have a double-layer counter-rotating blade disc, resulting in low oil fume purification efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a high-efficiency oil fume purification device to solve the problems in the prior art. The specific technical solution is as follows: A high-efficiency oil fume purification device includes a sound wave focusing device, a transducer inside the sound wave focusing device, a spray device fixed at the upper end of the sound wave focusing device, an atomizer inside the spray device, and a mechanical centrifugal separation device fixed at the upper end of the sound wave focusing device. The sound wave focusing device, the spray device, and the mechanical centrifugal separation device are internally interconnected.

[0004] Furthermore, the sound wave focusing device includes a housing, an air inlet at the lower end of the housing, an observation window on the side of the housing, and a transducer disposed inside the housing.

[0005] Furthermore, the spraying device includes a second housing, which is fixed to the upper end of the first housing and communicates with the interior of the first housing. The atomizer is fixed to the inner wall of the second housing, and a water inlet pipe is connected to the end of the atomizer.

[0006] Furthermore, the mechanical centrifugal separation device includes a lower housing, which is fixed to the upper end of the second housing, and the inner wall of the lower housing is fluid-type and contracts upward.

[0007] Furthermore, an upper shell is fixed to the upper end of the lower shell, and the interiors of shell one, shell two, lower shell and upper shell are interconnected. An air outlet is provided on the side of the upper shell.

[0008] Furthermore, a bracket is fixed to the upper end of the upper housing, and a motor is fixed to the upper end of the bracket. The output end of the motor is connected to a coupling, and the coupling is connected to an inner shaft.

[0009] Furthermore, a lower blade disk is fixed to the lower end of the inner shaft.

[0010] Furthermore, a second motor is fixed to the side of the upper housing. The output end of the second motor is connected to a first rotating wheel. The first rotating wheel is connected to the second rotating wheel via a conveyor belt. The second rotating wheel is fixedly connected to the outer shaft. Both the second rotating wheel and the outer shaft are rotatably connected to the inner shaft.

[0011] Furthermore, an upper blade disk is fixed to the lower end of the outer shaft.

[0012] Furthermore, the upper housing is provided with an oil guide groove.

[0013] The advantages of this utility model are: The cooking fumes enter the acoustic focusing device from the bottom, pass through the acoustic focusing device, a spray device, and a mechanical centrifugal separator in sequence, and are discharged from the top of the mechanical centrifugal separator. The transducer in the acoustic focusing device generates a high-intensity sound field, which causes micron- and submicron-sized fine particles to move relative to each other, increasing the probability of collision between particles. This causes the fine particles to aggregate into larger particles. The atomizer in the spray device sprays the fumes. When the spray droplets collide with the fumes, the surface tension, van der Waals force, and electrostatic attraction of the droplets cause the fumes to adhere to the droplet surface and agglomerate. The mechanical centrifugal separator guides the flow of the fumes, increases the centrifugal force of the particles, and achieves efficient separation of the particles, thereby improving the fume purification efficiency and reducing the impact of fumes on the environment and human health.

[0017] Example 1 like Figures 1-3 As shown, a high-efficiency oil fume purification device includes a sound wave gathering device, a transducer inside the sound wave gathering device, a spray device fixed at the upper end of the sound wave gathering device, an atomizer 5 inside the spray device, and a mechanical centrifugal separation device fixed at the upper end of the sound wave gathering device. The sound wave gathering device, the spray device and the mechanical centrifugal separation device are internally interconnected. The working principle of the above technical solution is as follows: Oil fumes enter the acoustic gathering device from the lower end, pass through the acoustic gathering device, spray device, and mechanical centrifugal separator in sequence, and are discharged from the upper end of the mechanical centrifugal separator. The transducer in the acoustic gathering device generates a high-intensity sound field, causing micron- and submicron-sized fine particles to move relative to each other, increasing the probability of collisions between particles, thus causing the fine particles to aggregate into larger particles. The atomizer 5 in the spray device sprays the oil fume. When the spray droplets collide with the oil fume particles, the surface tension, van der Waals force, and electrostatic attraction of the droplets cause the oil fume particles to adhere to the droplet surface and agglomerate. The mechanical centrifugal separator guides the oil fume gas, increasing the centrifugal force of the particles, achieving efficient separation of particles, thereby improving the oil fume purification efficiency and reducing the impact of oil fume emissions on the environment and human health.

[0018] Example 2 like Figures 1-3 As shown, the sound wave focusing device includes a housing 1, an air inlet 2 at the lower end of the housing 1, an observation window 3 on the side of the housing 1, and a transducer disposed inside the housing 1. The working principle of the above technical solution is as follows: the oil fume enters the housing 1 through the air inlet 2. The transducer can generate a high-intensity sound field, which causes micron- and submicron-sized fine particles to move relative to each other, increasing the probability of collision between particles, thereby causing the fine particles to aggregate into larger particles. The observation window 3 can be used to observe the oil fume purification status.

[0019] Example 3 like Figures 1-3 As shown, the spraying device includes a second housing 4, which is fixed to the upper end of a first housing 1 and communicates with the interior of the first housing 1. An atomizer 5 is fixed to the inner wall of the second housing 4, and a water inlet pipe 6 is connected to the end of the atomizer 5. The working principle of the above technical solution is as follows: water is supplied to the atomizer 5 through the water inlet pipe 6. The atomizer 5 atomizes the water. When the fine water mist collides with the oil fume particles, the surface tension, van der Waals force and electrostatic attraction of the droplets cause the oil fume particles to adhere to the surface of the droplets and agglomerate.

[0020] Example 4 like Figures 1-3 As shown, the mechanical centrifugal separation device includes a lower housing 7, which is fixed to the upper end of the housing 4, and the inner wall of the lower housing 7 is fluid-type and contracts upward.

[0021] The upper end of the lower housing 7 is fixed with the upper housing 8. The housing 1, housing 2, lower housing 7 and upper housing 8 are internally interconnected. The upper housing 8 is provided with an air outlet 9 on its side. The working principle of the above technical solution is as follows: the oil fumes, after being processed by the sound wave focusing device and the spray device in sequence, enter the upper shell 8 through the lower shell 7 and are discharged through the air outlet 9.

[0022] Example 5 like Figures 1-3 As shown, a bracket 10 is fixed to the upper end of the upper housing 8, and a motor 11 is fixed to the upper end of the bracket 10. The output end of the motor 11 is connected to the coupling 12, and the coupling 12 is connected to the inner shaft 13. The lower end of the inner shaft 13 is fixed with a lower blade disk 14; The upper housing 8 has a second motor 15 fixed on its side. The output end of the second motor 15 is connected to the first rotating wheel 16. The first rotating wheel 16 is connected to the second rotating wheel 18 via the conveyor belt 17. The second rotating wheel 18 is fixedly connected to the outer shaft 19. Both the second rotating wheel 18 and the outer shaft 19 are rotatably connected to the inner shaft 13. The lower end of the outer shaft 19 is fixed with an upper blade disk 20; The working principle of the above technical solution is as follows: Starting motor 11 drives coupling 12 to rotate, which in turn drives inner shaft 13 to rotate, and lower blade disk 14 to rotate. Starting motor 215 drives impeller 16 to rotate, which in turn drives impeller 218 to rotate via conveyor belt 17, which in turn drives outer shaft 19 to rotate, and upper blade disk 20 to rotate. Lower blade disk 14 and upper blade disk 20 rotate in opposite directions. When the oil fume is between the two blade disks, there is a process of tangential velocity changing direction, which increases the relative velocity between the particles and the blades, increases the probability of particles colliding with the blade surface, and achieves effective capture of oil fume particles. Under the action of centrifugal force of high-speed rotation, the oil fume particles, due to their high density, are thrown onto the inner wall of upper shell 8, achieving efficient separation and improving the overall purification efficiency of the equipment.

[0023] Example 6 like Figures 1-3 As shown, the upper housing 8 is provided with an oil guide groove 21; The working principle of the above technical solution is as follows: After the oil fume particles are thrown onto the inner wall of the upper shell 8, they slide down into the oil guide groove 21 under the action of gravity.
