摘要： There are provided a dust collector and method for collecting dust in which the rarefaction of a dielectric at the rear part of electric field forming means is prevented, whereby the collecting efficiency can be increased. The dust collector includes charging means 1 for charging a substance to be collected 9, such as dust and mist, contained in a gas; spray means 2 for spraying a dielectric 10 on the substance to be collected 9 charged by the charging means 1; electric field forming means 3, having first and second electrodes 11 and 12 for forming a direct current electric field, for dielectrically polarizing the dielectric 10 sprayed by the spray means 2 by means of the direct current electric field; and dielectric collecting means 16 for collecting the dielectric 10 which has arrested the substance to be collected 9, the spray means 2 being provided with grounding means 17 and 18 for electrically grounding the dielectric 10 before being sprayed to let a charge of the dielectric 10 escape.

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Divisional of co-pending U.S. patent application Ser. No. 09/635,430 filed Aug. 10, 2000, the entire contents of which are incorporated herein by reference in their entirety. Thereupon, in the dust collector of embodiment 1, the spray section is formed as shown in FIG. 4. This spray section is configured so that an earth net 17 is disposed in the nozzle 6, and an earth net 18 is disposed at a slightly nulldownstreamnull upstream position from the position where the nozzle 6 is disposed in the pipe 7. When this two fluid nozzle 60 is used, an earth net 20 is disposed at the outlet of the introduction pipe 61, and an earth net 21 is disposed at a slightly nulldownstreamnull upstream position from the position where the nozzle 60 is disposed in the pipe 7. Thereby, the deelectrified dielectric 10 is sprayed from the nozzle 60 as in the case of the nozzle 6 shown in FIG. 4.
