- the outlet cover 12b is provided with a discharge pipe 14b, and the inlet pipe 14a and the discharge pipe 14b are installed in the middle of the compressed air pipe.
- the filter means 20a, 20b charges the filter element 120 to the filter body 121 made of a polymer synthetic resin film such as polypropylene or polyethylene by a corona discharge device of ⁇ 40 kv, thereby providing positive (+) polarity and A filter body in which a plurality of gap maintaining protrusions 122 are formed at the same time of depositing (granting) a negative polarity (electrostatic charge), and at the same time as the above charges, the gap maintaining protrusions 122 are formed ( 121 is cylindrically wound to form a vent 123, and the filter element 120 uses the embodiment described in Korean Patent No. 481289 of the applicant of the present invention, and other details of the filter element 120.
- the filter main body 121 is charged by cutting the polymer synthetic resin to a certain width, or charging the wide polymer synthetic resin and then cutting the polymer synthetic resin to a predetermined width.
- the filter element 120 is formed into an arc-shaped (shade or mountain) cross section to form the filters 21 and 22, and then the filters 21X22 are opposed to each other, and the surroundings are mutually joined to each other to form a cavity ( C) is formed to form filter means 20a, 20b.
- the filters 21 and 22 are formed by forming the filter element 120 in the arcuate cross section as shown in Fig. 2, and then providing the shape retaining members 130a and 130b on both sides and the periphery thereof.

- the solid foreign matter contained in the compressed air is charged with the charge (electrostatic) permanently imparted to the filter element 120, so that fine (0.3 micron or less) solid foreign matter is collected, and the gas of inorganic and organic compounds The smell is also collected.
- the pressure in the cavity C is different from the space portion S1, and the pressure of the cavity C Since the center and the outer circumference have a distance difference from the surface of the filter 21, the pressure difference between the core and the outer circumference causes the compressed air in the cavity C to vortex to disturb (turbulence), thereby filtering the filter element 120 of the filter 22.
- the filter means in the filter means 20b By the same action as the means 20a, the foreign matter or the like is recollected or collected.
- the dust that occupies most of the solid foreign matter is asymmetric bar, needle or flake (flakes), and most of the dust has polarity, and the non-polar dust also has a film body ( Solid matters and the like are collected in the filter element 120 while having a polarity by the charge imparted to 121, and when the dust is collected in this manner, the compressed air to be purified is decompressed, vortex or disturbed, and the pressure at each site is reduced. In this case, when the air flow passage 123 formed in the filter element 120 passes through (pass) at different angles, the purification efficiency is greatly improved.
- the compressed air to be purified as described above is depressurized and vortexed or disturbed, and the pressure of each part is different, when the solid foreign matter or the like is charged with the charge imparted to the film main body 121, the compressed air passes through. Since the inertia can be kept smaller than the electric field (magnetic field) strength of the charge imparted to the film main body 121, the purification efficiency can be maintained well.
- the compressed air collected through the final filter means is discharged into the pipeline through the discharge pipe 14b while maintaining the pressure-reduced state in the space S3.
- the dust collection effect is increased since the strength of the electric field (electric field) of the charge imparted to the filter main body 121 is increased.
- the present invention provides at least two or more sets of filter means in which a cavity having an arc cross section is mutually opposed to each other so as to form a cavity therein. Inserting the inlet / outlet cover and the space between the filter means and the filter means so as to form a space therebetween, the pressure between the center and the outer peripheral surface of the cavity formed inside the filter means while reducing the compressed air, By turbulent or turbulent turbulence of the compressed air, the purification efficiency can be greatly improved and the purification efficiency can be maintained well.
