Off-line radial electric dust remover and method

The invention discloses an off-line type radial electric dust collector, belongs to the technical field of electrostatic dust collector equipment, and aims to solve the problem of low dust collection efficiency, the off-line type radial electric dust collector comprises a plurality of off-line dust collection chambers, each off-line dust collection chamber is internally provided with a groove type anode dust collection part, a cathode dust collection part, a first baffle and a second baffle, a first dust collection cavity is formed between the adjacent groove-shaped anode dust collection part and the second baffle, the cathode dust collection part is arranged in the first dust collection cavity and matched with the groove-shaped anode dust collection part, and a second dust collection cavity is formed between the groove-shaped anode dust collection part and the lifting valve. The cathode dust collection part is connected with a high-voltage power supply, so that dust is adsorbed on the anode dust collection p
