[0002] Electrostatic precipitators are highly efficient oil fume purification devices widely used in catering, hotels, food processing, and other industries. An electrostatic precipitator contains an electrostatic field. When gas containing oil and dust particles passes through the electrodes, the oil and dust particles become charged under the influence of the electric field and are adsorbed onto the electrodes, thus purifying the gas. After a period of use, a large amount of oil and dust particles accumulate on the electrodes, affecting the purification effect; therefore, regular cleaning is necessary.

The alkali solution in the caustic washing box 5 soaks the entire static electric field, and the vibration device is started to make the alkali solution vibrate, accelerating the oil stains and dust particles to fall off from the surface of the electric field, so as to achieve the cleaning effect. After soaking and cleaning for 10-20 minutes, the stacking machine 1 moves the cleaned static electric field to the rinsing box 6 through the clamp 9 for rinsing, so that the alkali solution and the falling dirt on the surface of the electric field are washed away, and then the rinsed static electric field is moved to the drying box 7 for drying the moisture on the surface of the electric field, thus completing the cleaning of the static electric field.

Figure 6 As shown, or the sewage treatment system 2 is arranged beside the caustic washing box 5, the rinsing box 6 and the drying box 7, which can reduce the overall height of the automatic cleaning electrostatic field production line, and is suitable for use in an area with insufficient height in a production workshop.

[0058] Optionally, the spray head 63 is a umbrella-shaped spray head 63. The umbrella-shaped spray head 63 has better uniformity in the overall coverage area. Preferably, the adjacent two rows of spray heads 63 are staggered to avoid the occurrence of a blind area.

The electrostatic field sequentially passes through the alkali washing, flushing and drying processes, so as to realize the automatic cleaning function of the electrostatic field, and the cleaning efficiency is high, and each electric field is uniformly cleaned to achieve consistent cleaning effect.

[0061] During the alkali washing, a plurality of alkali washing tanks 5 work simultaneously, and the ultrasonic generator 51 is used to vibrate the alkali solution, and the heating device 52 is used to heat the alkali solution, so that the oil stains and dust particles on the surface of the electric field are quickly stripped, so as to achieve higher cleaning efficiency.
