<p><P>PROBLEM TO BE SOLVED: To provide a deduster adapted so that the dust collection efficiency may be improved by preventing a dielectric from suffering from concentration thinning at the rear part of an electric field forming means. <P>SOLUTION: The deduster is provided with a charging means that charges a substance to be collected, such as dust or mist, contained in a gas; a spray means that sprays a dielectric onto the charged substance charged by the charging means; an electric field forming means that generates a DC electric field rectangularly crossing the direction of the flow of the above gas, has a meshed electrode having a high opening degree not to interfere with the flow of the gas, and causes the dielectric polarization of the above dielectric by means of the above DC electric field; and a dielectric collecting means collecting the dielectric which has collected the substance to be collected. It is also possible that the electric field is generated by the dielectric itself by charging the dielectric. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
