To provide an electric dust collector for a tunnel which can improve dust collection efficiency.
In an electric dust collector equipped with a charging part for charging particulates in gas introduced from a tunnel and a dust collection part for collecting the charged particulates in the gas passing through the charging particulates, the charging part has a plate-shaped discharge electrode 5 extending in the flow direction of the particulates and dust collection electrodes 4 arranged opposite to each other and parallel to both sides of the discharge electrode 5, and projections 12 are formed in parallel on the electrode 4 side of the discharge electrode 5. Since the projections 12 are directed to the electrode 4, a region of large electric field strength is formed between it and the electrode 4 to increase a discharge current sufficiently. Even when high flow velocity gas is intruded into a gas charging part, the particulates can be charged efficiently, and the charged particulates can be collected efficiently in the dust collection part.
