Description

Technical Field

[0001] This utility model belongs to the technical field of electrostatic oil fume removal equipment. Background Technology

[0002] In the field of oil fume treatment, electrostatic precipitators are the mainstream equipment currently used. After a period of use, oil and grease accumulate on the electric field module, leading to decreased processing efficiency and potential safety hazards. Therefore, cleaning of the electric field module is necessary. In the specific industry of kitchen oil fume purification, in addition to efficiently treating oil fumes, the ability to perform automatic cleaning is equally important. Generally, only large-scale electrostatic precipitators are equipped with automatic cleaning functions, and even then, automatic cleaning usually requires a pressurized water pump, resulting in a complex structure and relatively high manufacturing costs.

[0003] In recent years, domestic patent databases have published several similar technical reports on electrostatic grease removal devices: [Application No.] ZL2014201965356, [Name] A High-Efficiency and Easy-to-Clean Electrostatic Grease Removal System, [Publication No.] CN203853169U, discloses a high-efficiency and easy-to-clean electrostatic grease removal system, including an air inlet pipe, an air outlet pipe, and an electrostatic grease removal module. The electrostatic grease removal module is connected to both the air inlet and outlet pipes. Each module includes multiple independently configured electrostatic grease removal units, which are vertically arranged, connected to the outlet pipe at the top and the air inlet pipe at the bottom. Each unit has an airflow regulating valve at its top or bottom to control the airflow volume. The airflow regulating valve adjusts the amount of exhaust gas entering each electrostatic grease removal unit. However, this device still suffers from problems such as inability to automatically clean, easy soiling, and short lifespan. Summary of the Invention

[0004] This utility model provides a horizontal electrostatic precipitator with automatic cleaning capabilities, featuring a reasonable installation structure, low manufacturing cost, relatively simple production process, good cleaning effect, and long service life. It solves the technical problems of current devices being easily contaminated, inconvenient to clean and maintain, and resulting in short service life.

[0005] This utility model provides an automatically cleanable horizontal electrostatic precipitator for removing oil fumes, including a plate wire electric field for filtering oil fumes, an electrical control box for controlling the operation of the plate wire electric field, and a main housing for mounting the plate wire electric field. The top of the main housing is equipped with lifting rings for easy hoisting. Both ends of the main housing have connecting flanges for connection to external mechanical structures. The plate wire electric field is installed inside the main housing, the electrical control box is installed on the outer side of the main housing, cleaning spray bars are installed inside the main housing, and a plate wire electric field is installed between every two cleaning spray bars. An inlet flange is located on the outer side of the main housing, and the inlet flange and electrical control box are located on opposite sides of the main housing. The machine feet are fixedly installed at the bottom of the main housing, and the oil and water outlet is fixedly installed at the bottom of the main housing. The cleaning spray bar includes a fixed end and a rotating movable end, and a rotating spray bar. The fixed end includes a first thread and a first recess. The rotating movable end includes a groove, a first step, a first internal fixing groove, and a fixing screw hole. The rotating movable end includes a second step, a second pipe thread, and a second groove. A bushing is fitted on the rotating movable end, with one end of the bushing close to the second step of the rotating movable end. The bushing and the rotating movable end are placed together into the first internal fixing groove of the fixed end. The sealing plate passes through the second pipe thread of the rotating movable end and contacts the fixed end. The sealing plate screw hole of the sealing plate is coaxial with the fixing screw hole of the fixed end. The fixing nut is threaded to connect the sealing plate screw hole of the sealing plate with the fixing screw hole of the fixed end. The second pipe thread of the rotating movable end is threaded to the first through thread of the tee connector. One end of the rotating spray rod is threaded to the second through thread of the tee connector. The other end of the rotating spray rod is threaded with a water pipe plug. The first spray hole and the second spray hole are through hole structures on the rotating spray rod. The rotating spray rod is composed of two pipe sections assembled together.

[0006] The main unit housing has connecting flanges at both ends for connection to external mechanical structures. The external mechanical structures can be ventilation ducts, with one end responsible for air intake and the other end responsible for air exhaust. The other end can also be connected to multiple sets of duct-type horizontal electrostatic precipitators to form a stronger fume removal capability.

[0007] This invention employs a plate-wire electric field design, with cleaning spray bars on both sides simultaneously cleaning the plate-wire electric field for a more thorough clean. The nozzles on the spray bars spray clean water onto the plate-wire electric field. Due to the pressure of the water pump, the clean water is sprayed onto the inner and outer walls of the plate-wire electric field, thus cleaning it. Simultaneously, wastewater flows out through the oil-water drain outlet of the main unit casing. After a period of operation, the electric field remains relatively clean, enabling the equipment to operate continuously and efficiently. Furthermore, this equipment has a simple structure, is easy to operate, and has low maintenance costs. It solves the technical problems of current devices, such as susceptibility to contamination, inconvenient cleaning and maintenance, and short service life. It boasts advantages such as a reasonable installation structure, low manufacturing cost, relatively simple production process, strong self-cleaning ability, high self-cleaning effect, and long service life.

Detailed Implementation

[0015] The present invention will be further described below with reference to the specific accompanying drawings and embodiments.

[0016] like Figure 1-6As shown, this utility model mainly includes a plate wire electric field 6 for filtering oil fumes, an electrical control box 4 for controlling the operation of the plate wire electric field 6, a main unit housing 3 for installing the plate wire electric field 6, a lifting ring 2 for easy hoisting installed on the top of the main unit housing 3, and connecting flanges 1 at both ends of the main unit housing 3 for connecting to ventilation ducts. The plate wire electric field 6 is installed inside the main unit housing 3, the electrical control box 4 is installed on the outer side of the main unit housing 3, and cleaning spray bars 5 are installed inside the main unit housing 3. One plate wire electric field is installed between every two cleaning spray bars 5. 6. The inlet flange 7 is located on the outer side of the main unit housing 3. The inlet flange 7 and the electrical control box 4 are located on opposite sides of the main unit housing 3. The machine feet 8 are fixedly installed at the bottom of the main unit housing 3. The oil and water outlet 9 is fixedly installed at the bottom of the main unit housing 3. The cleaning spray bar 5 includes a fixed end 51, a rotating movable end 517, and a rotating spray bar 519. The fixed end 51 includes a first thread 52, a first groove 53, a first step 54, a first internal fixing groove 55, and a fixing screw hole 56. The rotating movable end 517 includes a second step 57. The second thread 58 and the second groove 59 are connected. The bushing 510 is fitted onto the rotating movable end 517, with one end of the bushing 510 abutting against the second step 57 of the rotating movable end 517. The bushing 510 and the rotating movable end 517 are inserted together into the first internal fixing groove 55 of the fixed end 51. The sealing plate 511 passes through the second thread 58 of the rotating movable end 517 and contacts the fixed end 51. The sealing plate screw hole 512 of the sealing plate 511 is coaxial with the fixing screw hole 56 of the fixed end 51. The fixing nut 516 is threaded onto the sealing plate 511. The sealing plate screw hole 512 is connected to the fixing screw hole 56 of the fixed end 51. The second thread 58 of the rotating movable end 517 is connected to the first thread of the tee connector 518. One end of the rotating spray rod 519 is threadedly connected to the second thread of the tee connector 518 through the rotating spray rod thread 513. The other end of the rotating spray rod 519 is threadedly fitted with a water pipe plug cap 520. The first spray hole 514 and the second spray hole 515 are through holes on the rotating spray rod 519. The rotating spray rod 519 is composed of two sections of pipe assembled together. The inlet flange 7 is connected to the external water inlet pipe by bolts.

[0017] I. During oil fume removal operation: The electrical control box 4 generates high voltage through its internal transformer module, which is then supplied to the plate wire electric field 6. Oily fumes enter the main unit casing 3 through the connecting flange 1. When oil fume molecules pass over the plate wire electric field 6, they adhere to the inside of the plate wire electric field 6 due to the electric field force. When the oil molecules accumulate to a certain volume, they will naturally flow down the inner wall of the plate wire electric field 6 due to gravity, thereby achieving the purpose of oil fume removal.

[0018] II. Automatic Cleaning Operation: When the equipment is not in operation and cleaning is required, the control box 4 issues a cleaning command. The transformer module inside the control box 4 stops working and stops outputting high-voltage static electricity. Simultaneously, it starts working, delivering external cleaning water through the inlet flange 7 to the cleaning spray bar 5. The first spray hole 514 on the cleaning spray bar 5 sprays clean water onto the plate wire electric field 6. The second spray hole 515 sprays water onto the inner wall of the main unit casing 3. Since the second spray holes 515 of the rotating spray bar 519 at both ends of the cleaning spray bar 5 are in opposite directions, the water sprayed from the second spray holes 515 at both ends is in opposite directions. The reaction force of the water spray can cause the rotating spray bar 519 to drive the rotating movable end 517 to rotate relative to the fixed end 51, thereby uniformly cleaning the plate wire electric field 6, and the electric field is cleaned. At the same time, the wastewater flows out through the oil-water discharge port 9. After a period of operation, the electric field can maintain a relatively clean state after cleaning, enabling the equipment to continue to operate efficiently.
