る。 Conventional electrostatic dielectric filter media include filter media that utilizes the negative chargeability of polypropylene fibers.
It is attached to a one-stage or two-stage charging type device that is composed of an ionization section made up of a high-voltage discharge wire and a ground electrode, and a dust aggregation section and a dust collection section made up of a high-potential electrode plate and a ground electrode plate, and a positive voltage is applied. Because all dust particles are collected and filtered on the same surface, clogging occurs quickly.There are also filter media that contain a mixture of negatively charged and positively charged fibers, but this problem can be alleviated to some extent.
At present, it is still only surface filtration, and a bleed filter is installed in front of the filter medium. In addition, if only negatively charged filter media is used in an electrostatic dielectric air conditioner, there is a risk that sparks will be generated between the filter media and the positive electrode, causing the filter media to melt, creating holes, or causing a fire. There is.

なる積層ウエブを構成する。 As shown in the drawing, in the upper layer a, fibers such as polyester, rayon, nylon, etc. having a fineness in the range of 10 to 30 deniers (preferably 15 to 30 deniers) are used as positively (+) chargeable fibers 1. Alternatively, a mixed web with a weight of 80 to 120 g/m 2 is used, and the lower layer C contains Teflon or polychloride with a small fineness in the range of 10 to 3 deniers as the negatively charged fiber 2. Made of fibers such as vinyl, vinyl chloride-acrylic copolymer, acrylic, polypropylene, etc., weighing 20~
A 40 g/m 2 web was used, and as an intermediate layer b, the positively chargeable fibers 1 of large fineness used in the upper layer were mixed with the negatively chargeable fibers 2 of small fineness used in the lower layer. Weight 40~60g/ m2
A laminated web having a three-layer structure each having different dielectric properties is formed by forming a web of three layers.

た。 For example, the upper layer a is a bulky fiber layer with a weight of 100 g/ m2 made of 100% (weight ratio) of 15 denier polyester fibers, and the middle layer b is a bulky fiber layer of 50% (weight ratio) of 15 denier polyester fibers and 3 denier fibers. Fibers with a weight of 50 g/m 2 and lower layer C made of mixed fibers with 50% (weight ratio) of acrylic-vinyl chloride copolymer fibers
A three-layer laminated fiber layer with a weight of 170 g/m 2 is formed using only 3-denier acrylic-vinyl chloride copolymer fibers with a weight of 20 g/m 2 , and is sprayed with a synthetic resin or synthetic rubber binder. They were bonded together by processing such as impregnation treatment to form an electrostatic dielectric filter medium 3 having a density gradient in the thickness (cross-sectional) direction.

The upper layer of the filter medium is repelled, but coarse dust is collected by the sieving action, and the dust that has passed through the upper layer is negatively charged with a stronger force due to the balance of positive and negative charges in the middle layer. is collected in the fibers of In addition, the positively charged electrical dust that has passed through the intermediate layer is composed only of negatively charged fibers, and the lower layer with high fiber density has the effect of being completely captured by a stronger suction force, resulting in an extremely increased dust capacity. do.

This filter medium has the effect of covering all of the above. Furthermore, since the upper layer of the filter medium is positively charged, damage to the filter medium and fire caused by sparks generated between the positive electrodes of the discharge section can be prevented, and this invention has various effects.
