DUST PRECIPITATOR AND AIR CONDITIONER

PROBLEM TO BE SOLVED: To resolve problems in a dust precipitator composed of a charging part using discharge, a precipitation part consisting of positive and precipiration electrode plates provided on both sides of an integrally formed air passage body, and an air fan in this order, wherein dust introduced in the precipitator is charged at the charging part and removed in the latter stage precipitation part forming an electric field by laminating flat electrodes with constant spaces and applying voltage, while deflection of the positive electrode plates and dust precipitation electrode plates prevents the constant space therebetween from being kept and a uniform electric field in the space from being obtained, to cause uneven dust precipitation. SOLUTION: In this dust precipitator, completely insulated type electrodes 2 formed by coating the whole of a sheet-like conductive material with an insulation material, and corrugatedly formed non-conductive corrugated electrodes 1 provided with an electrode terminal 5 at an optional part of a sheet-like non-conductive material 4, are alternately laminated to constitute the precipitation part 3. Different voltages are applied to the completely insulated type electrodes 2 and non-conductive corrugated electrodes 1, respectively. COPYRIGHT: (C)2007,JPO&INPIT
