Abstract

Oppositely charged electrode cones or electrode cylinders are adjustably supported so that one cone or cylinder is within the other cone or cylinder but spaced therefrom, whereby air currents attracted to and flowing through the electrostatic field have particles of impurity acquire the charge of one of the electrodes and are repelled to be collected on and adhere to the other electrode cone or cylinder. Specifically the cones are made of fiberglass and the adjacent faces of the cones are coated with fiberglass wool. The cylinders may be of larger diameter and may be made of steel.

GAYLOED ATTORNEY DEVICE FOR-CLEARING IMPURITIES FROM THE ATMOSPHERE BACKGROUND OF THE INVENTION The use of electrostatic field in a manner to use oppositely charged elements spaced apart so as to charge of the spacing between the electrodes in accordance with .the atmospheric conditions, and to enable the arrangement of the size and number of electrodes in such a manner as to accomplish the purification of large masses of air,,particularly to provide a device whereby air could be treated and purified in sufficiently large masses to free the atmosphere of so-called smog.

DETAILED DESCRIPTION In the illustrative embodiment of the inventionshown in FIGS. 1 to 5 inclusive, a plurality of outer dialectric cones 1 are supported in registry with matching dialectric inner cones 2. On the frame 3 which supports the outer dialect'ric cones l in a predetermined pattern,

are also supported a plurality of fans or blowers 4 electricallyoperated for thepurpose of circulating air and blowing the air through the smaller end 6 of the outer cone 1 and then-through the smaller end 7 of the inner cone 2 and through the space 8 between the cones 1 cone 1 is made of dielectric material, preferably fiberglass, and the inner surface thereof is'co'ated with fiberglass wool 17 as indicated in FIG. 5. The inner cone 2 has a conductor wire 18 cemented to its inner periphery as shown in FIG. 5 and the outer periphery of the inner cone 2 has a coating of fiberglass wool 19. Ex-

perimentally the following proportions were found I about one-quarter of an inch thick.

The conductor wire 16 is connected by suitable wires 21 to one terminal of suitable source of electricity and the inner wire 18 is connected by suitable wires 22 to the opposite terminal of suitable source of electricity whereby an electrostatic field is created between the cones. I

The intensity of the electrostatic field is determined by the potential difference between the opposite electrodes formed'by the inner and outer cones and it also can be varied by the relative position of the adjustable inner cones 18. The unit is surrounded by a suitable wall, such as tent walls 23, shown in FIG. 1 so as to form a windbreak at about the ground level.

Thus the air from the atmosphere is drawn into the.

area by the fans or blowers 4 and it is forced to flow through-the open ends ofthe/cone electrodes 1 and 2. As the air travels from the smaller end of 'the outer cone 1 toward the smaller end of the inner cone 2, the particles acquire the same charge as that of the outer electrode 1' and are repelled from the outer cone and fly against the surfaces of the inner cones 2 and adhere thereto and are collected thereon. Such of the particles which may acquire the charge of the inner cone 2 fly against and adhere to and are collected on the inner surface of the outer cone 1. v

In practice the spacing between the inner periphery of the outer cone 1 and the outer periphery of the inner conev 2 is normally about four inches depending on weather conditions and other atmospheric conditions and may be separated even as far as shown in FIG. 4.

The connector wires 21 and 22 which supply opposite charges to the dielectric cones 1 and 2 respectively, are connected to a generator of current supply of about 45,000 volts to each set of outer and inner cones. The cones will capture practically all particles,

even finest molecular particles and also gases. As the air passes through and around the cones these particles and material, deposits itself on the cones and on all surfaces thereof. The suction fans or blowers draw in and circulate the air in and around the cones.

In the form shown in FIGS. 6 to 11 an outer dielectric drum 31 is permanently supported on a stand 32. A replaceable inner drum 33 is supported by means of a hub 34 on spokes 36 on a central shaft 37 on a base 38.

The inner drum 33 can be thus replaced by a larger drum 39 shown in FIGS. 10 and nor by a drum 41 of smaller circumference shown in FIGS. 8 or 9 thereby respectively to reduce or increase the gap, and the corresponding field between the outer and inner drums. These drums are also'charged through suitable wiring with current of about 45,000 volts and they are effective to greater distances. Batteries of such sets of drums can be arranged pointing upwardly.
