本発明は低圧力損失で高効率であり、高粉塵保持容量で
長寿命の高性能エアーフィルタの構成に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to the construction of a high performance air filter with low pressure loss, high efficiency, high dust holding capacity and long life.
従来、エアーフィルタは嵩高な不縁布フィルタが一般に
用いられている。上記フィルタは一般に高効率のもの程

フィルタ自体の寿命も短かくなり、管理費用も増加する
欠点がある。BACKGROUND ART Conventionally, bulky unlined cloth filters have generally been used as air filters. The above-mentioned filters are generally characterized in that the higher the efficiency, the higher the pressure loss, and the lower the efficiency, the lower the pressure loss. Therefore, when using a high-efficiency filter, as the pressure loss increases, mechanical equipment such as the fan of the air machine needs to be larger, which increases equipment fees, shortens the life of the air filter itself, and increases management costs. There is also the disadvantage of increasing
最近かかる高効率の用途が増加し、低圧力損失で高効率
、かつ高粉塵容量のエアーフィルタが試みられている。Recently, such high-efficiency applications have increased, and air filters with low pressure loss, high efficiency, and high dust capacity are being attempted.

どの問題がある。For example, there are some air filters in which the surface of the constituent fibers of nonwoven fabrics is coated with a sticky liquid such as Km-converted paraffin or phosphate ester, and the dust-collecting ability is improved by the adhesive force. It is difficult to apply it uniformly to the fiber surface, especially in high-efficiency air filters because the fiber density is high. Therefore, there are many areas where the sticky liquid does not adhere, making it impossible to achieve the desired efficiency increase. Furthermore, if an excessive amount of sticky liquid is applied, a dripping phenomenon occurs during use, causing problems such as adhering stains on machines and the like, and peeling of paint.

寿命が翅かいという欠点がある。ｔたその製作に数々の
制約、困難が伴うのでコスト高となる問題点がある。On the other hand, there is a structure in which the powder layer is captured by the dielectric force of an electric filter formed by charging fibers, but although high efficiency can be expected with low pressure loss from the initial stage, the dielectric force captures the powder layer all at once. Because it has the property of gathering
The disadvantage is that it has a short lifespan. However, there are many restrictions and difficulties involved in its production, which poses the problem of high costs.
