- LAWRENCE N- oRscnER, F ENTERPRISE, .KANsas'AssIeNoR TO WILLIAM L HRSAM AND LAWRENCE N. MoRsonER;oo' rRUs'rEEs, 0F ENTERPRISE, KANSAS.
' To all whom it may concerns Be it known that I, LAWRENCE N. MOR-' APPARATUS FOR ELECTRICAL SEPARATION OF PARTIcLEsrRom A mma STREAM.
soHER, a citizen of the United States, residmg at Enterprlse, in the county of Dickinson and State of Kansas, have invented certain new and useful Improvements in Apparatus for Electrical Separation of Particles from a Fluid Stream, of which the following is a specification. 1
The object of my invention is to produce an apparatus .for the separation of particles from a poorly conductlng fluid streannby drivingthe particleladen fluid-stream through the electrical field between two opposite members charged with high potential.
of opposite signs, one of said members being adapted to discharge readily while the other member is arranged to prevent discharge as far as possible, and providing 'means for catching the repelled particles in such manner as to remove them from the influence of the electrical field, the velocity of the par: ticle-laden fluid-stream'and the arrangement of the particle-arresting members'b'eing such as to ractically prevent the charged and re,- p'elled particles from contacting with the non-discharging member. I I The accompanying drawings'illustrate my invention: p
.Figure 1 is a plan of an apparatus embodying my invention; Fig.2 a partial vertical section thereof; Fig. '3 a plan'of a modified form, and Fig. 4 a vertical section on line: 44 of Fig. 3..
In order to accomphsh desired results. I
provide a chamber 10 which is preferably I substantially circular in cross section and has a circular wall 11 of conductingmaterial such, for instance, as sheet iron. Leading into chamber 10 is a tangentiall arranged induction passage 12 through w 'ch the particlel-aden fluid-stream is driven at a considerable velocity. The top 13 of the chamber is formed preferably of a non-conducting material, and is provided with a central eye '13' The eye 13 is extended into the chamber 10 by means of a cylinder 1 4 which is preferabl. o conducting material. Projected throug the cylinder 14 is an. insulatingtub'e '15 suitably supported-by bracket 16 and projected through the tube 15 is a wire 17 connected 'with a suitable source high potential P grounded at G; The inner end of the conductor 17 is connected to a'conductor 18 which is preferably a reticulated dlSk having- Specification of Letters Patent;

final diameter of thechamber 10 and presentlng a shar edge or a ringofsharp points to the inner ace of'the wall 11. The wall 11 is grounded.
In the form shownin Figs. and 2 the chamber 10 is rovided with a hopper bottom 19 which ischarges into a sultable receiver 20. In the form shown in Figs. 3 and 4 the bottom-21 of the chamber is flat and is adapted to be swept by brushes 22 which are carried by arms or disks 23 carried by a shaft 24 j ournaled in the'b'ottom 21 and adapted to sweep the bottom 21 mtoadischarge stop 25.
v In operation, the discharging electrode 18 is given. a charge of high potential and this will induce in the wt} 11 a charge of high potential of the: opposite sign. The article laden: fluid stream, such as dustaden air or gas forinstance, is then driven through the passage 12 into thechamber 10 thus setting up 'a-cyclonic action in a well understood ma er.- This action has a normal tendency to cause a separation of the particles from the flui stream by centrifugal action, but, where the-\particles are hght and fine, a good separation can not be .accomplished in this manner alone. When the parts are electrically charged in the manner described, however, the I articles are violently repelled downwar through the reticulated-con uctor 18 and dropping either into the insulated hopper 19 or upon the insulated floor 21from whence they are removed from the electrical field,
the cleaned fluid-stream gassing outwar from the chamber 10 throu the annulus 14. The guard 14 gradually ac uires apotentlal assing easily approximating that ofthe ielectric bathing it, and therefore the' dust does not cling to this guard but drops into the hopper.
I have found by experiment that where an electrical field is established between'two parallel surfaces of considerable area and a particle-laden fluid-stream is passed between such char ed conductors man of the line and very buoyant particles W11 be set into violent vibration and will not-be readily sep-' arable from the fluid stream. If however,
one of the conductors be directed toward a de ression in the other conductor. the violent vi rations of the particles is eliminated. In the form shown in the drawings it will be noticed thatany given ortion of the edge of the dischar'glng con uctor 18 is directed into, said chamber also having tion passage leading therefrom.
toward a cupped portion of the conductor 11 and experiments show that in such form the particle separation is accomplished, with great efliciency. It will be readily under-;
stood that the circuits may be reversed so that the induced charge is on the conductor 18, but I prefer the arrangement shown.
