In the electrostatic precipitator provided in the embodiment of the present application, when the dust-laden exhaust gas needs to be purified, the dust-laden exhaust gas enters the dust collection box 11 through the air inlet pipe 111. Then the dust-containing waste gas enters into an electrostatic dust removal machine core 12 contained in a dust removal group, an electrode plate is arranged in the electrostatic dust removal machine core 12 and comprises an anode electrode plate and a cathode electrode plate, and the anode electrode plate and the cathode electrode plate form a high-voltage electrostatic field; under the action of the electric field force of the high-voltage electrostatic field, the dust-containing waste gas is ionized, and charges are adsorbed on dust particles to enable the dust particles to be charged, so that the dust particles directionally move to the electrode plates in the electric field, and the dust particles are separated from the dust-containing waste gas to form purified clean gas. Finally, the clean gas is discharged out of the dust removal box 11 through the air outlet pipe 112.

After the electrostatic precipitator works for a period of time, a large amount of dust, especially sticky dust containing a large amount of greasy dirt, adheres to the electrode plate of the electrostatic precipitator core 12, especially the anode electrode plate, so that the electrode plate needs to be subjected to ash cleaning treatment.

It can be understood that the water supply device can only supply cleaning water to the dust-removing box 11 when the electrode plates of the electrostatic dust-removing machine core 12 need to be cleaned; in the working process of the electrostatic precipitator core 12 for purifying the dust-containing waste gas, the water supply device does not supply clean water to the dust-removing box 11.

An inspection manhole 110 is provided at a position of the top of the dust removing box 11 corresponding to the dust removing group so as to install, inspect and replace the electrostatic dust removing core 12 and the ultrasonic vibration plate 13.

Thus, the negative pressure in the dust removing box 11 can be avoided to suck water into the dust removing box 11, and external air can be prevented from entering the dust removing box 11 through the water supply pipe 23, the first overflow pipe 31 and the water discharge pipe 32; that is, the water supply pipe 23, the first overflow pipe 31 and the water discharge pipe 32 are all in a water sealed state.

In addition, two manual valves are provided corresponding to the water pump 22, one being provided on an inlet pipe (not shown in the figure) of the water pump 22, the other being a first manual valve 230 provided on the water supply pipe 23 (the water supply pipe 23 being an outlet pipe of the water pump 22); the water pump 22 is isolated under the condition that the two manual valves are closed at the same time, so that the water pump 22 can be disassembled, replaced, overhauled and the like. A second manual valve 310 is attached to the first overflow pipe 31, and a third manual valve 321 is attached to the drain pipe 32.
