[0006] The utility model provides an electrostatic oil fume removal equipment with automatic cleaning and fire protection functions, including an electrostatic main unit for filtering oil fume.

The second main water pipe is fixedly connected to the third main water pipe. The first main water pipe, the second main water pipe, and the third main water pipe form a passage. The first pipe thread straight-through is fixedly welded to the third main water pipe. One end of the height-adjustable water pipe is installed on the first pipe thread straight-through through a pipe thread, and the other end of the height-adjustable water pipe is installed with an elbow through a pipe thread, and the elbow is installed with a spiral nozzle through a pipe thread.

By monitoring the temperature inside the electrostatic main body through the fire temperature sensor rod, when a high-temperature condition is detected, the fire water valve can be controlled to open through the control circuit to cool down the electrostatic main body for fire protection, solving the technical problems that the current device is prone to pollution, inconvenient to clean and maintain, and in the electrostatic oil fume removal occasion, the traditional bearing structure is prone to the corrosion of the balls or the jamming of the balls due to the penetration and scaling of the oil fume, resulting in a short service life. It has the advantages of reasonable installation structure, low manufacturing cost, relatively simple production process, strong self-cleaning ability, high self-cleaning effect, long service life, and good fire protection effect.

[0032] As Figure 1-3 shown, the fire water pipe 12 is connected to the second electric valve 14. The second electric valve 14 is connected to the first fire sprinkler 27 through a pipeline.

[0034] As Figure 7-8 shown, the non-ball bearing mechanism 286 includes a fixed end 2861 and a rotating and movable end 2866. The fixed end 2861 is composed of a first pipe thread 2862, a first groove 2863, a first fixed step 2864, a fixed groove 2865, and a first screw hole 28614 structure. The rotating and movable end 2866 includes a second fixed step 2867, a second pipe thread 2868, and a second groove 2869 structure. The rotating and movable end 2866 is placed in the fixed groove 2865 of the fixed end 2861. The bushing 28610 is installed outside the rotating and movable end 2866 and is located in the fixed groove 2865 of the fixed end 2861.

[0035] As Figure 4 shown, the rotating spray bar 288 includes a third pipe thread 2881, a first water spray hole 2882, a second water spray hole 2883, and a third water spray hole 2884.

[0036] As Figure 5As shown, the second pipe thread straight-through 285 is fixedly welded to the third main water pipe 289. The fixed end 2861 of the non-ball bearing mechanism 286 is installed on the second pipe thread straight-through 285 through the pipe thread of the first pipe thread 2862. The pipe thread tee 287 is connected to the second pipe thread 2868 of the rotating movable end 2866 of the non-ball bearing mechanism 286 through the pipe thread. The other two connections of the pipe thread tee 287 are connected to the third pipe thread 2881 of the rotating spray bar 288 through the pipe thread.

[0037] During operation, 1. During the oil fume removal operation: The control electric cabinet generates high voltage through the internal transformer module and transmits it to the first electric field modules 23 and the second electric field modules 24 of the first-stage electrostatic module group 2, the second-stage electrostatic module group 3, and the third-stage electrostatic module group 4. The oil fume-containing waste gas passes through the air inlet fire damper 5 and the air inlet reducer 7 in sequence and then enters the electrostatic main unit 1. When the oil fume molecules pass through the first-stage electrostatic module group 2, the second-stage electrostatic module group 3, and the third-stage electrostatic module group 4, they will adhere to the inner surfaces of the first electric field modules 23 and the second electric field modules 24 due to the action of the electric field force. When the oil fume molecules accumulate to a certain volume, they will flow down naturally on the inner walls of the first electric field modules 23 and the second electric field modules 24 due to gravity and are discharged through the first oil drain port 21, thus achieving the purpose of oil fume removal. The gas after electrostatic adsorption is discharged after passing through the air outlet reducer 8 and the air outlet fire damper 6.

[0038] II. During automatic cleaning operation: When the equipment does not need to run and needs to be cleaned, the control cabinet issues a cleaning instruction, the transformer module inside the control cabinet stops working, and the output of high-voltage static electricity stops; at the same time, the air inlet fire damper 5 and the air outlet fire damper 6 are closed, and the automatic cleaning circulating water pipe 11 extracts cleaning water from the circulating water tank 9 through the first electric valve 13 and transports the cleaning water to the first main water pipe 29. One cleaning route of the cleaning water is to pass through the first main water pipe 29, the second main water pipe 28, the third main water pipe 289, and the height-adjustable water pipe 282 in sequence and is sprayed out through the spiral nozzle 284. Another cleaning route of the cleaning water is to pass through the first main water pipe 29, the second main water pipe 28, the third main water pipe 289, the non-ball bearing mechanism 286, and the rotating spray rod 288 in sequence and is sprayed out through the first water spraying holes 2882, the second water spraying holes 2883, and the third water spraying holes 2884 of the rotating spray rod 288. Due to the action of gravity and water pump pressure, the clear water is sprayed from top to bottom on the inner and outer walls of the first electric field module 23 and the second electric field module 24 of the first-stage static electricity module group 2, the second-stage static electricity module group 3, and the third-stage static electricity module group 4, and the electric field is cleaned. Then it flows into the circulating water tank 9 arranged directly below the static electricity main unit 1 through the first drain port 22. Due to the fact that oil and water do not mix with each other and oil has a lower density than water, the oil stain will automatically form a layer on the upper part of the water tank, and the clear water will form a layer on the lower part of the water tank. After running for a period of time, the electric field can maintain a relatively clean state after cleaning, enabling the equipment to operate continuously and efficiently.

[0039] III. During fire fighting operation, when the first fire temperature sensor rod 25 and the second fire temperature sensor rod 26 installed inside the static electricity main unit 1 sense that the temperature inside the static electricity main unit 1 is too high, the control cabinet issues a fire fighting instruction, the transformer module inside the control cabinet stops working, and the output of high-voltage static electricity stops. At the same time, the air inlet fire damper 5 and the air outlet fire damper 6 are closed, and the control cabinet controls the second electric valve 14 to open. The water in the fire fighting water pipe 12 is sprayed onto the first-stage static electricity module group 2, the second-stage static electricity module group 3, and the third-stage static electricity module group 4 through the first fire sprinkler 27. The fire fighting water flows into the circulating water tank 9 arranged directly below the static electricity main unit 1 through the first drain port 22.
