Description
INV ENTOR ATTORNEY FIG.5.
. Patented Mar. 8, 1932 UNITED STATES PATENT OFFICE JOEN' E. FEDLELEB, OF NEW YORK, N. Y.
emcnmuna Application filed January 16, 1928. Serial No. 247,148.
My invention more particularly relates to means for separating gaseous from non-gaseous material, in which the means are self-' forming old and well-known means into new combinations for coating and cleaning the same. 'The object I particularly desire to attain is to provide an eflicient exhaust air cleaner which maybe attached to the present centrifugal dust collector drums now commonl employed on exhaust systems of mills an manufacturing plants. Since the destructive effects of dust have been recognized, means to confine the same have been desired. In several states, labor laws have been enacted prohibiting the operation of mill saws and bulfing machines unless they are provided with exhausters drawing the dust and air away from the operator of the machine, and at the same time other laws prohibiting the free exhaust of the dust-laden air from mills into the atmosphere. A millowner is thus forced to em 10y a dust collector, and the sim lest of t ese is a vertical drum in which the inlet is at a' tangent to the periphery, and the outlet of the air is at the top, and the outlet of the dust in a conesha ed bottom.
he rapidly moving air entering this drum creates a cyclone within the drum, which arrests and collects the heavier dust particles by centrifugal action, but carries the lighter ones out into the atmosphere with the air. Such a device is therefore usually placed on the outside of a building, and is satisfactory to,
the workman within the building, but it is ineflicient at all times and wasteful of heat units in the winter months, or in colder climates.
In myinvention I have provided a device which is placed over the outlet of a cyclone dust collector, and which will collect the finer dust'and can, therefore, be placed on the inside of a building so that the heat units are not wasted because the air canQbe used over again.
My invention will be best understood by referring to the accompanying drawings in which I have illustrated a preferred emobdi ment of the same, and in which Fig. 1 shows an assembled top view of the device with some of the filter mediums in place.
Fig. 2 is a sectional view on line V-V of Fig. l.
Fig. 3 is an illustrative section of line XX of Fig. 1.
Fig. 4 is an illustrative section of line ZZ of Fig. 1. 1
Fig. 5 illustrates the relative position of my device on a cyclone dust collector 30.
Like reference characters indicate like parts throughout the drawings.
Referring now to Figs. 1 and 2 of the drawings, 10 is the cylindrical casing, 12 is the cyllndrical inlet, and 11 is the bottom of an open pan, cylinder 10 is provided with a means to strengthen the outside upper edgeover at the ends, to which ring-formed angle 20 is secured; one leg of this angle is wider to form a shallow outside cylinder to the in ner frame. An inner cylinder 23 is fastened and suspended from T- irons 21 and 22, and
It will be observed that the filter mediums are enclosed in a frame work and angular flange which is supported within cylinder upon angle 14, and is a removable unit.
In an air cleaner, the heavier particles are easily removed by a cyclone dust collector, or shaking screens, but the finer particles are more difiicult to collect. Fine screens become choked up, particularly if a liquid is used to clean them, because of the capillary attraction of the liquid which holds the liquid and dirt in the mesh. Experience verifies that frequent change of direction of a current of air by baflles coated with a liquid is a more eificient way to trap the dust. Dry battles allow the fine dust to blow through, but when the bafiiesare coated with a liquid, the dust particles get stuck in this moisture, becomes moist itself, and other particles attach themselves to form the mud found on the baffles.
1 In my invention, I have taken advantage of this experience and though a number of formsofbafiles and filter mediums maybeused, I have elected to introduce here a series of bafiles composed of rods of suitable material and length, the ends of which are enlarged, or are provided with short ferrules so that when they are placed on top, or alongside of each other, an open slot is formed between the rods, as wide as the rods are enlarged at the ends, or as the ferrules allow for. These rods may be of wood boiled in creosote or paraffin. They are assembled staggered, as shown in section Figures 3 and l. The ferruled part of the rods rest upon angle 24 on the inner end and upon angle 20 on the outer end, This feature has an advantage inasmuch as the baflles ofl'er more resistance near the center where they are deeper than further out, thus equalizing the flow of air. These baflles may be tied together in bundles to facilitate their removal and renewal, but these bundles must be formed to allow for the difference in depth on the inner and outer ends of the rods.
On top of cover 25 a sprinkler 26, like the ordinary revolving lawn sprinkler, is secured and connected with a source of liquid, such as water or oil by pipe 27, and controlled by a valve 28. The nozzles of these sprinklers are usually adjustable, and when used in combination with my device, the must be adjusted to spray liquid upon the afiles within the confines of cylinder 10. The liquid passing down over the bafile rods 29 with a tendenc to flow toward cylinder 23 upon the be e plate projection, because of the anfilllarly disposed bafile rods 29. The liquid ally flows into the pan and out through pigsahli e air flows up from the cyclone dust collector through cylinder 12 as indicated by arrow, passm outward under the bafile projection of cy 'nder 23 and finally up through the coated, or moistened rods, which act as bullies and interrupt the dust particles which adhere to them and are carried back into the pan, where they collect or flow out of drain 15 with the liquid. In this case, it will be observed that the downward flowing liquid coats and cleans the bafile units.
When the device is used to clean air for ventilating purposes the intake of a blower may be connected to cylindrical inside of pan, and the air will then flow downward with the liquid.
Having thus described my invention, what I claim as new and desire to cover by Letters Patent is:
1. In combination with a conduit for dust laden air or gas, a cleaner unit mounted in entrapping liquid films, and means for divert ing the flow of the dust laden air or gas through said filter means.
2. In combination with a conduit for dust laden air or gas, a cleaner unit mounted in superposed relation to the conduit outlet, said unit comprising a casing having an inlet to register with the conduit outlet, a bafile dome mounted in the casing in opposed relation to said inlet, an annular filter means supported within said casing between the battle dome and the casing wall, said bafile dome having means for directing the dust laden air or gas laterally and upwardly through the filter means, means carried by said unit for discharging liquid upon said filter means, and means embodied in said cleaner unit for collecting and draining the liquid therefrom.
3. In an air or gas cleaner, a casing having an air inlet, a bafile mounted in the casing in opposed relation to said inlet, and an annular staggered filter means transversely bridging the space between said battle and the casing wall and composed of a multiplicity of closely spaced filter members, whereby the streams of dust laden gas or air are deflected tion of the dust therefrom.

5. In an air or gas cleaner, a casing having an inlet, a bafile dome mounted in the 4. In an air or gas cleaner, a casing having casing with its open side op osed to said-inlet and having means for irecting the air or gas laterally within the casing, a multiplicity of closely massed radially disposed filter rods supported at their ends upon the casing wall and the baflle dome respectively to provide a substantially continuous annular 'filter means surrounding said dome, and means for discharging a liquid upon said filter members.
6. In combination with a conduit for dust laden air or gas, 'a-cleaner unit mounted in' superposed relation Within the outlet portion of said conduit, consisting of a cylindrical casing, a concentrically disposed inner cylinde'r with a cone-shaped baflie for deflecting the flowof air within said conduit, and a plurality of staggered transverse filter rods concentrically placed around the inner cylinder, whereby the streams of dust laden gas or air deflected by the cone-shaped baflle are impacted against said filter rods and deprived of the dust present therein.
