Description

Technical Field

[0001] This utility model belongs to the field of oil fume purification technology, and specifically relates to an oil fume purifier. Background Technology

[0002] With the increasing environmental awareness of the general public, their demands on themselves and their surrounding environment are also rising, making the prevention and control of air pollution a top priority. Oil fume pollution has become a key focus of current environmental remediation efforts. Large amounts of fumes containing oil and soot are generated in cooking at hotels, restaurants, canteens in schools and government offices, and food processing workshops that involve frying and cooking. The emission of these fumes into the atmosphere not only pollutes the environment with waste oil particles or soot, but also poses health risks. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and provide an oil fume purifier with reasonable design and strong practicality. After the oil fume enters the oil fume purifier, it passes through a pre-filter to remove larger oil fume particles and impurities, and then enters an electrostatic field device. The high-voltage electric field causes the fine particles in the oil fume to become charged, and they aggregate and settle under the action of the electric field, further ionizing the oil fume particles. Finally, the oil fume passes through a medium-efficiency filter to remove even smaller particles and odors, improving purification efficiency, ensuring that the purified flue gas meets emission standards, and reducing the pollution of oil fume to the environment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An oil fume purifier includes a housing with a purification chamber inside. One end of the housing has a smoke inlet, and the other end has a smoke outlet. The smoke inlet and outlet are connected to the purification chamber. Within the purification chamber, from the smoke inlet to the smoke outlet, a pre-filter plate, an electrostatic field device, and a medium-efficiency filter plate are arranged sequentially. After entering the purifier through the smoke inlet, the oil fumes first pass through the pre-filter plate to remove larger oil fume particles and impurities. Then, they enter the electrostatic field device, where a high-voltage electric field charges the fine particles in the oil fume, causing them to aggregate and settle under the influence of the electric field, further ionizing the oil fume particles. Finally, the oil fume passes through the medium-efficiency filter plate to remove even smaller particles and odors before being discharged from the smoke outlet. This improves purification efficiency, ensures that the purified flue gas meets emission standards, and reduces the pollution of oil fumes to the environment.

[0006] Furthermore, a control cabinet is installed on the side of the enclosure, with an inspection cabinet door and control buttons on the door. The control cabinet is located separately on one side of the enclosure, which improves the ease of operation and makes it convenient for operators to use. The inspection cabinet door allows for easy disassembly and repair of the components inside the control cabinet, facilitating subsequent maintenance.

[0007] Furthermore, the control cabinet has heat dissipation slots on its side walls. The design of these slots can improve the heat dissipation performance of the control cabinet, ensure stable operation of the equipment, and extend its service life.

[0008] Furthermore, a support frame is provided on the back of the box, which facilitates the hanging and installation of the box.

[0009] Furthermore, two sets of limiting components are installed inside the purification chamber. The two sets of limiting components are located on the upper and lower sides of the electrostatic field device, respectively. The pre-filter screen and the medium-efficiency filter screen are respectively installed on the two sets of limiting components. The two sets of limiting components correspond to the pre-filter screen and the medium-efficiency filter screen, respectively, which facilitates the stable placement of the two filter screens in the purification chamber.

[0010] Furthermore, the limiting assembly includes two symmetrically arranged limiting frames. Each limiting frame includes a main frame and a support plate. The main frame is fixedly connected to the inner wall of the box. A limiting plate is provided on the main frame, and a limiting groove is formed between the limiting plate and the support plate. The pre-filter screen and the medium-efficiency filter screen are limited and supported in the limiting groove. Each limiting assembly includes two limiting frames, which are symmetrically arranged on both sides of the filter screen. The filter screen is limited and installed between the two limiting frames, effectively ensuring the stability and balance of the installation. A limiting plate is formed by bending on the main frame, and a limiting groove is formed between the limiting plate and the support plate for quick installation and positioning of the filter screen, greatly improving installation efficiency. Reinforcing folds are provided on the sides of the limiting plate and the support plate to improve structural strength, making the limiting plate and the support plate less prone to deformation and ensuring stable support for the filter screen.

[0011] Furthermore, the main frame is provided with perforated slots, and the tray is provided with limit cards. The limit cards correspond one-to-one with the perforated slots. The limit cards pass through the corresponding perforated slots and are attached to the side of the main frame for limitation. The limit cards located at both ends of the main frame are fixed to the main frame with screws. The design is reasonable. The limit cards correspond one-to-one with the perforated slots, which facilitates the precise splicing and positioning between the tray and the main frame. The tray is then further fixed with screws. The installation and disassembly are convenient, and the connection between the tray and the main frame can be ensured to be firm and reliable.

[0012] Furthermore, a limiting cavity is formed between the upper and lower sets of limiting components, and the electrostatic field device is installed in the limiting cavity. The limiting cavity formed between the two sets of limiting components is just right for the limiting installation of the electrostatic field device. The overall structure is reasonable and ingenious.

[0013] Furthermore, the electrostatic field device includes an electrostatic frame, a first gradient electric field, and a second gradient electric field. Both the first and second gradient electric fields are located within the electrostatic frame, with the second gradient electric field positioned above the first gradient electric field. The discharge spacing of the first gradient electric field is larger than that of the second gradient electric field. This ingenious and reasonable structural design enables graded filtration of particulate matter in cooking fumes through the two gradient electric fields. The first gradient electric field can capture larger particles, while the second gradient electric field further captures smaller particles, thereby improving the overall purification efficiency. The superposition of the two gradient electric fields makes the electric field strength of the entire electrostatic field device more uniform and stable, further enhancing the capture efficiency of particulate matter and improving the purification quality.

[0014] Furthermore, both the inlet and outlet of the smoke are provided with folded edges on their sides. The folded edge design can enhance the structural stability of the inlet and outlet of the smoke, making the inlet and outlet of the smoke less prone to deformation.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] This invention is reasonably designed and highly practical. After the oil fumes enter the oil fume purifier, they pass through a pre-filter to remove larger oil fume particles and impurities. Then, they enter an electrostatic field device. The high-voltage electric field charges the fine particles in the oil fume, causing them to aggregate and settle under the influence of the electric field, further ionizing the oil fume particles. Finally, the oil fume passes through a medium-efficiency filter to remove even smaller particles and odors, improving purification efficiency and ensuring that the purified flue gas meets emission standards, thus reducing the pollution of oil fumes to the environment.

Detailed Implementation

[0031] like Figures 1 to 12As shown, this utility model discloses an oil fume purifier, comprising a housing 1, a purification chamber 2 inside the housing 1, an inlet 4 at one end of the housing 1, and an outlet 3 at the other end of the housing 1. The inlet 4 and outlet 3 are connected to the purification chamber 2. Within the purification chamber 2, from the inlet 4 to the outlet 3, a pre-filter plate 5, an electrostatic field device 6, and a medium-efficiency filter plate 7 are sequentially arranged. After entering the oil fume purifier 25 through the inlet 4, the oil fumes first pass through the pre-filter plate 5 to remove larger oil fume particles and impurities, then enter the electrostatic field device 6. The high-voltage electric field charges the fine particles in the oil fume, causing them to aggregate and settle under the influence of the electric field, further ionizing the oil fume particles. Finally, the oil fume passes through the medium-efficiency filter plate 7 to remove even smaller particles and odors, and is discharged from the outlet 3, improving purification efficiency, ensuring that the purified flue gas meets emission standards, and reducing oil fume pollution to the environment. Both the smoke inlet 4 and the smoke outlet 3 have folded edges on their sides. The folded edge design can enhance the structural stability of the smoke inlet and outlet ports, making them less prone to deformation.

[0032] A support frame 12 is provided on the back of the enclosure 1, which facilitates the hanging and installation of the enclosure 1. A control cabinet 8 is provided on the side of the enclosure 1. The control cabinet 8 has an inspection door 10 and control buttons 9. The control cabinet 8 is located on one side of the enclosure 1, which improves the ease of operation and makes it convenient for operators to use. The inspection door 10 allows for easy disassembly and repair of the components inside the control cabinet 8, facilitating subsequent maintenance. The side wall of the control cabinet 8 is provided with heat dissipation slots 11. The design of the heat dissipation slots 11 improves the heat dissipation performance of the control cabinet 8, ensures stable operation of the equipment, and extends its service life.

[0033] Two sets of limiting components are installed inside the purification chamber 2. These two sets of limiting components are located on the upper and lower sides of the electrostatic field device 6, respectively. The pre-filter plate 5 and the medium-efficiency filter plate 7 are respectively installed on the two sets of limiting components, which correspond to the pre-filter plate 5 and the medium-efficiency filter plate 7, facilitating the stable placement of the two filter plates in the purification chamber 2. Each limiting component includes two symmetrically arranged limiting frames 13. Each limiting frame 13 includes a main frame 14 and a support plate 15. The main frame 14 is fixedly connected to the inner wall of the housing 1. A limiting plate 16 is provided on the main frame 14, forming a limiting groove 17 between the limiting plate 16 and the support plate 15. The pre-filter plate 5 and the medium-efficiency filter plate 7 are limited and supported within the limiting groove 17. Each limiting component includes two limiting frames 13, which are symmetrically arranged on both sides of the filter plate. The filter screen is positioned between two limiting frames 13, effectively ensuring placement stability and balance. A limiting plate 16 is formed by bending on the main frame 14, and a limiting groove 17 is formed between the limiting plate 16 and the support plate 15 for quick installation and positioning of the filter screen, greatly improving installation efficiency. The sides of the limiting plate 16 and the support plate 15 are provided with reinforced folds to improve structural strength, making the limiting plate 16 and the support plate 15 less prone to deformation, ensuring stable support for the filter screen.

[0034] The main frame 14 is provided with perforated slots 18, and the tray 15 is provided with limit cards 19. The limit cards 19 correspond one-to-one with the perforated slots 18. The limit cards 19 pass through the corresponding perforated slots 18 and are attached to the side of the main frame 14 for limitation. The limit cards 19 located at both ends of the main frame 14 are fixed to the main frame 14 with screws. The design is reasonable. The limit cards 19 correspond one-to-one with the perforated slots 18, which facilitates the precise splicing and positioning between the tray 15 and the main frame 14. The tray is then further fixed with screws. The installation and disassembly are convenient, and the connection between the tray 15 and the main frame 14 is firm and reliable.

[0035] A limiting cavity 20 is formed between the upper and lower sets of limiting components. The electrostatic field device 6 is installed within the limiting cavity 20. The limiting cavity 20 formed between the two sets of limiting components is used for the limiting installation of the electrostatic field device 6. The overall structural layout is reasonable and ingenious. The electrostatic field device 6 includes an electrostatic frame 21, a first gradient electric field 22, and a second gradient electric field 23. Both the first gradient electric field 22 and the second gradient electric field 23 are located within the electrostatic frame 21. The second gradient electric field 23 is located above the first gradient electric field 22. The discharge spacing of the first gradient electric field 22 is larger than that of the second gradient electric field 23. The structural design is ingenious and reasonable. Through the two gradient electric fields, the grading filtration of particulate matter in the fumes is achieved. The first gradient electric field 22 can capture large particles, while the second gradient electric field 23 further captures smaller particles, thereby improving the overall purification efficiency. The superposition design of the two gradient electric fields makes the electric field strength of the entire electrostatic field device 6 more uniform and stable, which is more conducive to improving the capture efficiency of particulate matter and improving the purification quality.

[0036] This utility model is reasonably designed and highly practical. After the oil fumes enter the oil fume purifier 25 through the inlet 4, they first pass through the pre-filter plate 5 to remove larger oil fume particles and impurities. Then, they enter the electrostatic field device 6, where a high-voltage electric field charges the fine particles in the oil fume, causing them to aggregate and settle under the influence of the electric field, further ionizing the oil fume particles. Finally, the oil fume passes through the medium-efficiency filter plate 7 to remove even smaller particles and odors, and is discharged from the outlet 3. This improves purification efficiency, ensures that the purified flue gas meets emission standards, and reduces the pollution of oil fumes to the environment. Both the inlet 4 and outlet 3 have folded edges on their sides. This folded edge design enhances the structural stability of the inlet and outlet ports, making them less prone to deformation. In actual use, the oil fume purifier 25 of this utility model can be directly assembled with the range hood 24 into a single unit (e.g., Figure 12 Installed before the range hood fan 26, the fume purifier 25 treats the fumes before they pass through the fan 26. This not only treats the fumes but also prevents particulate impurities in the fumes from affecting the fan 26. The fume purifier 25 can also function as a standalone module, directly connected to the exhaust vent of the range hood 24, allowing fumes from the range hood 24 to be treated in the purifier 25 before being discharged.
