である。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electret honeycomb filter that can efficiently collect particles suspended in gas, and is useful, for example, for cleaning air in rooms, cars, etc., and cleaning devices for electronic copying machines. In particular, the present invention relates to an electret honeycomb filter that has a wide range of uses, such as secondary dust collectors, air intake sections of devices that dislike dust, and exhaust sections of devices that generate dust.

ダスト捕集を行なうことは困難となる。Prior Art Conventionally, as a device for collecting particles (dust) suspended in gas, cotton-like or non-woven filter bags (
or filter plate), and for larger sizes, electrostatic precipitators, cyclone filters, etc. are generally known. However, with filter bag and filter plate type dust collection filters, the pressure drop increases significantly as dust is collected, and the collection efficiency decreases over time, resulting in a short filter life (replacement cycle). There is a problem with paddles. In addition, in order to extend the lifetime of such a filter, it is necessary to increase the overlapping area of the Ikioi filter, but in this case,
As with electrostatic precipitators, the device becomes larger and heavier, making it difficult to easily collect dust.

The electret honeycomb filter according to the present invention is formed into a honeycomb structure using an electret film, and is configured such that the half side of the inner wall of each fly comb cell (unit) is a positive polarity surface and the other side surface is a negative polarity surface. .

クトレットシート１が得られる。After depositing a conductive substance on one side of a sheet with a thickness of about 10 to 50 μm that is suitable for electret, such as pFA (bar fluoroalkoxy 7) or FEP (fluoroethylene propylene), corona irradiation or Ion beam irradiation is performed to turn the sheet into an electret (the evaporated layer is grounded and serves as a counter electrode during irradiation). After the electret formation is completed, the deposited layer may be left as is or may be removed. In this way, as shown in FIG. 1, an electret sheet 1 is obtained in which one side of the sheet has positive polarity and the other side has negative polarity.

Further, the length of the helical cam structure 3 in the axial direction (air inflow direction) can be freely set, and the longer it is, the better the particle collection ability is.
