The invention discloses a multi-pole distribution combination type current inversion efficient electric precipitator which comprises a shell, common electric field positive plates, common electric field negative poles, grating and blind positive plates, end electric field negative poles, front deflection baffles and rear deflection baffles. A smoke inlet is formed in the front end of the shell. A smoke outlet is formed in the rear end of the shell. The front deflection baffles are mounted at the front ends of the corresponding grating and blind positive plates. A first channel is formed behind each front deflection baffle. The front end of each first channel is sealed. The rear end of each first channel communicates with the smoke outlet. The rear deflection baffles are mounted at the rear ends of the grating and blind positive plates. A second channel is formed in front of each rear deflection baffle. The front ends of the second channels communicate with a front containing cavity. The rear ends of the second channels are sealed. According to the multi-pole distribution combination type current inversion efficient electric precipitator, by changing the air flow flowing direction and the flowing speed for multiple times, increasing the dust impact frequency and the like, the problems of back corona and reentrainment of dust are prevented effectively, superfine dust is collected more efficiently, and the dust collection efficiency is improved.
