Rotary mobile electrostatic precipitator

A rotary mobile electrostatic precipitator comprises slide rails, a support, a rotating rod and a plurality of nozzles. The slide rails are parallelly disposed on two sides of a workpiece conveyor belt. The slide rails are as long as a dust removal chamber. The support comprises a transverse support and two vertical supports. The vertical supports capable of sliding along the slide rails are mounted on the slide rails. The vertical supports are connected through the transverse support. The rotating rod driven by a first motor to rotate is fixed to the middle of the transverse support. The nozzles spraying positively and negatively charged gas are mounted on the rotating rod. A second motor capable of driving the support to shift and slide on the slide rails is disposed under the slide rails. Both the first motor and the second motor are servo motors. The rotary mobile electrostatic precipitator can move with a movement of a workpiece; the nozzles rotate at high speed and spray the positively and negatively charged gas when the rotary mobile electrostatic precipitator moves; a workpiece is continuously dedusted from the time entering the dust removal chamber to the time exiting from the same; dedusting insufficiency caused by dedusting intervals is avoided.
