Abstract: PROBLEM TO BE SOLVED: To impart adhesion to dust and to prevent the re-scattering of the dust in a two-stage electrostatic precipitator consisting of a charging part and a dust collecting part by providing a spray nozzle for spraying an aq. soln. on the gas inlet side of the precipitator and automatically spraying the soln. when the dust collection rate is decreased below a set value. SOLUTION: When the precipitator is used in an automobile road tunnel, air and an aq. soln. are mixed by a spraying device 3 and sprayed into an exhaust gas introduced into the precipitator from a two-fluid spray nozzle, and hence the droplet is introduced into a charging part 1 along with the dust, passed through the field of a corona discharge generated by a DC high voltage impressed from a high-voltage power source 13 and charged. Subsequently, the duct and droplet are introduced into a dust collecting part 2 and collected on a collecting electrode 22 by the Coulomb force in a high electric field formed by a high-voltage power source 23. At this time, the dust concn. at the precipitator outlet is measured, the mixture is sprayed from the spray nozzle 31 when the concn. exceeds a specified value, and the rescattering is prevented.
