The invention provides a novel wire-pipe type diesel vehicle tail gas particle trap based on corona discharge. The wire-pipe type diesel vehicle tail gas particle trap comprises a charged part and a dust collection part. Bobbin type high-voltage pulse corona charging is adopted by the charged part, and bobbin type high-voltage negative direct current corona charging is adopted by the dust collection part which collects soot particles. Each barrel is provided with an electrode wire inlet and a high-temperature-resistant insulating conical plug, and electrode wire supporting discs are arranged in the barrels. The charged part and the dust collection part are connected in an insulated mode. After an engine is started, tail gas enters the charged part, and after the soot particles are fully charged, the soot particles enter the dust collection area along with the tail gas; and then the particles are further charged and then collected to the inner wall of a dust collection pipe under the action of electric field force, so that purification is completed. The purification structure is simple, purification efficiency is high, and the cost is low.
