The invention discloses a high-flow-speed wet-type electric dust remover which comprises a dust remover shell. An S-shaped air inlet is formed in the top of the dust remover shell. A cathode upper frame is arranged on the lower side of a retarding board. Cathode suspensions are arranged at the two ends of the side, near the retarding board, of the cathode upper frame. Cathode lines distributed atequal intervals are installed on the side, away from the cathode suspensions, of the cathode upper frame. A cathode lower frame is arranged at the ends, away from the cathode upper frame, of the cathode lines. A water filtration device is arranged on the lower side of the cathode lower frame. An anode assembly is arranged between every two connected cathode lines. An upper partition support and alower partition support are arranged at the two ends of each anode assembly. Anti-rocking devices are arranged on the upper sides of the lower partition support and the cathode lower frame. The anodeassemblies and the cathode lines are high in structural stability safety and good in dust removing effect, gas passes through the water filtration device before being emitted, and a rain floating phenomenon can be prevented.
