Title: Dielectric type air filter
Inventor: MORITA YOSHITAKA
IPC: B01D46/10
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent that the filter material of a dielectric type filter is moistened to be lowered in insulating properties and the dust collecting capacity thereof is lowered. SOLUTION: An upper layer filter material 3, a middle layer filter material 4 and a lower layer filter material 5 are interposed between electrodes 1, 2 and the middle layer filter material 4 is coarser than the other layers and a moisture absorbent 6 is arranged on the upper surface thereof. Since the moisture absorbent enters the middle layer filter material 4 according to air streams, the filter material is not moistened and the lowering of dust collecting capacity caused by the lowering of insulating properties is not generated. Further, there is also deodorizing effect such that a hydrophilic offensive smell component is adsorbed by the moisture absorbent. The filter material layers have a density gradient and, in its turn, have a gradient of electrostatic force and filter material thickness develops dust catching action equally to extend clogging life.
