Description

Technical Field

[0001] This utility model belongs to the technical field of oil fume purifiers, and specifically relates to an oil fume purifier with efficient oil-water separation function and easy maintenance, which is particularly suitable for scenarios with high oil fume concentration such as commercial kitchens. Specifically, it relates to an oil-water separation oil fume purifier. Background Technology

[0002] An oil fume purifier is a device for treating oily fumes. Common commercial oil fume purifiers usually use electrostatic treatment. Under the action of an applied high voltage, electrons are released from the surface or vicinity of the metal wire at the negative electrode and move rapidly toward the positive electrode. They collide with and ionize gas molecules. When the oily fumes pass through this high voltage electric field, the oil fume particles become charged in a very short time due to collisions and capture of gas ions. Under the action of the electric field force, they move toward the positive electrode dust collection plate, thereby achieving the separation effect.

[0003] In commercial fume purifiers, the electric field components typically adopt a pull-out installation structure (such as guide rails or slots) to facilitate daily maintenance and cleaning.

[0004] However, existing technologies have significant drawbacks: oil droplets in the fumes easily adhere to the surfaces of the guide rails or slots during the flow process, especially at the contact points between the electric field components and the supporting structure. Long-term accumulation of oil can lead to the following problems:

[0005] 1. Increased resistance when pulling the electric field components can easily cause jamming or even sticking, affecting maintenance efficiency;

[0006] 2. Accumulated oil stains are difficult to clean and require disassembly of the support structure for thorough cleaning, which is cumbersome.

[0007] 3. Oil residue may breed bacteria and produce odors, which does not meet food safety and hygiene standards.

[0008] To address the aforementioned issues, this application proposes an oil-water separation fume purifier. Utility Model Content

One side of the outer shell 1 is provided with a disassembly port 11 for disassembling and assembling the electric field component 4. A control box 3 is hinged to the side of the outer shell 1 at a position corresponding to the disassembly port 11. The control box 3 has a built-in high-voltage power module for providing a high-voltage electric field to the electric field component 4 (the operating voltage of the electric field component 4 in this utility model is 14-16KV). The support mechanism 6 includes a sheet metal bracket 61 fixed within the separation chamber 2 and a sheet metal support plate 62 disposed on the sheet metal bracket 61. The sheet metal support plate 62 is provided with an oil-guiding structure for guiding the flow of oil sludge, and the electric field component 4 can be pulled out and mounted on the sheet metal support plate 62.

[0032] Optionally, by Figure 1 and Figure 5 As shown, in this embodiment, the sheet metal support plate 62 includes an L-shaped support portion 623, and the oil guiding structure includes a main oil groove 621 and a guide portion 622. The L-shaped support portion 623 is used to support the edge of the electric field component 4. The main oil groove 621 is located below the L-shaped support portion 623. The guide portion 622 is inclinedly disposed between the L-shaped support portion 623 and the main oil groove 621 to guide the oil on the surface of the L-shaped support portion 623 into the main oil groove 621. The sheet metal support plate 62 also has a limiting portion 624, which protrudes from both sides of the L-shaped support portion 623 to limit the horizontal movement of the electric field component 4. The oil guiding structure also includes a secondary oil guiding groove 625, which is recessed on both sides of the limiting part 624 and extends along the length of the sheet metal bracket 61. It is used to collect oil dripping from the limiting part 624 to the outside. With the above solution, when in use, the sheet metal bracket 61 is fixed to the inner wall of the outer shell 1 by bolts to provide support for the sheet metal support plate 62. The sheet metal support plate 62 integrates the main oil guiding groove 621, the guide part 622, the L-shaped support part 623, the limiting part 624 and the secondary oil guiding groove 625, which are formed by bending a whole stainless steel plate.

[0033] The L-shaped support 623 contacts the edge of the electric field component 4, and the contact surface is smoothed to reduce the pulling resistance.

[0034] The guide section 622 is designed with an inclination angle of 15-30°, which can quickly guide the oil stains on the surface of the L-shaped support section 623 into the main oil groove 621;

[0035] The main oil trough 621 extends along the length of the sheet metal support plate 62 and has a U-shaped cross-section for collecting oil stains.

[0036] The auxiliary oil guide groove 625 is recessed on both sides of the limiting part 624, and has a U-shaped cross section. It is used to collect oil dripping from the limiting part 624 to the outside.

[0037] The limiting part 624 protrudes from both sides of the L-shaped support part 623 and is fitted with the edge of the electric field component 4 with a gap (gap ≤ 5mm) to prevent left and right swaying when pulled out.

[0038] Optionally, by Figures 1-3 As shown, in this embodiment, the electric field component 4 includes a porous plate 41, an anode cylinder 42, a cathode frame 43, and a cathode needle 44. The porous plate 41 has honeycomb-shaped perforations 411. The anode cylinder 42 is arranged corresponding to the honeycomb-shaped perforations 411. The cathode needle 44 is supported in the anode cylinder 42 by the cathode frame 43, and a high-voltage electric field is formed between the cathode needle 44 and the anode cylinder 42. With the above scheme, in use, two porous plates 41 are arranged at intervals, and the anode cylinder 42 is fixed between the two porous plates 41 and corresponds to the honeycomb-shaped perforations 411.

[0039] The anode cylinder 42 is set with honeycomb perforations 411 and serves as the positive electrode of the electric field component 4. It is made of hot-dip galvanized alloy steel plate, which is made by immersing the steel product after the surface has been cleaned and activated into molten zinc liquid. Through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is plated on the surface of the steel product.

[0040] The cathode holder 43 is made of insulating material;

[0041] One end of the cathode needle 44 is connected to the cathode holder 43, and the other end extends to the central axis of the anode cylinder 42, serving as the negative electrode of the electric field. The cathode needle 44 is made of 304 stainless steel, which is corrosion resistant and has good rigidity and conductivity.

[0042] In addition, the electric field assembly 4 also includes a porcelain insulator 45, which is disposed between the perforated plate 41 and the cathode holder 43 to provide insulation support between the perforated plate 41 and the cathode holder 43 and prevent high voltage leakage.

[0043] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes a pre-filter air distribution mesh 5. The pre-filter air distribution mesh 5 is detachably installed at the air inlet of the separation chamber 2 via a magnetic structure. The magnetic structure includes a second magnetic frame 10 located at the edge of the pre-filter air distribution mesh 5 and a first magnetic frame 9 located at the corresponding position on the outer shell 1. With the above solution, when in use, the pre-filter air distribution mesh 5 is made of metal mesh material and is magnetically connected to the second magnetic frame 10 on the outer shell 1 via the first magnetic frame 9, allowing for quick disassembly and cleaning.

[0044] Preferably, by Figure 1As shown, this embodiment also includes two L-shaped support legs 7 symmetrically fixed to the bottom of the outer shell 1 and a pull-out oil collection drawer 8 located between the two L-shaped support legs 7. The oil collection drawer 8 is located below the oil guiding structure of the support mechanism 6 and is used to collect oil sludge that flows down through the oil guiding structure. With the above solution, when in use, the oil sludge flowing out from the main oil groove 621 and the secondary oil guiding groove 625 enters the oil collection drawer 8 below under the action of gravity. When maintaining the equipment, the oil sludge inside can be cleaned by simply pulling out the oil collection drawer 8, which is convenient for cleaning.

[0047] Components not described in detail in this article are existing technologies.

[0048] The working principle and usage process of this utility model: When the oil fume purifier of this utility model is in use, the oil fume exhaust gas first passes through the pre-filter air distribution net 5, where large particulate impurities are intercepted and the airflow is made uniform.

[0049] The pretreated oil fume enters the separation chamber 2. Under the action of the high voltage electric field of the electric field component 4, the oil fume particles are charged and adsorbed onto the surface of the anode cylinder 42 to form an oil film.

[0050] The oil film flows down the inner wall of the anode cylinder 42 under the action of gravity, and some oil droplets fall onto the surface of the L-shaped support part 623 of the support mechanism 6;

[0051] Oil droplets enter the main oil tank 621 through the guide section 622, and finally flow into the lower oil collection drawer 8 under the action of gravity. Some oil droplets drip from the limiting section 624 to the outer side to the secondary guide oil tank 625, and finally flow into the lower oil collection drawer 8 under the action of gravity.

[0052] The purified gas is discharged through the air outlet of the separation chamber 2. The oil collection drawer 8 can be cleaned periodically by regularly removing the oil collection drawer.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
