To all whom 'it may comem:

Be it known that I, LAWRENCE N. MoR- scHER, a citi'zen of the United States, residing at Enterprise, in the county orf Diekmson and State of Kansas, have invented'certain new and useful Improvements in Apparatus for thev Separation. of Particles from -a of which the following 1s a specification. v

The object lo'f my invention is to produce an apparatus for the separation of part1cles from a poorly driving the particle-laden fluld-stream .into and-through an electrical field between two electrodes, one discharging toward the other.

A further object of my inventlon 1s to cause that electrode toward which the electrical discharge takes place, to move at a speed approximating that of the iuldstream andy in the same direction, whereby having become charged with sign as the dischargrepelled toward the when it reaches or ing electrode, will be moving electrode and,

approaches said electrode will, so far as the v electrodeA is concerned,

be in a substantial calm. v

A further object of my invention is to embody-the mechanism in such form that the particles may be urgedby centrifugal force in the same direction as that caused y the electrical action.

The accompanying drawings illustrate, an apparatus embodylng my invention. Y

Figure 1 is a partial vertical section and In the drawings, 10 indicates a cylindrical which it may' be rotated at any. desired speed. Mounted'within the electrodev 10 is a discharging electrode or electrodes 12 vwhich,l in the present case, are reticulateddisks presenting Ashar edges andpoints to facilitate electrical discharge, The electrodes 12 are connected by a suitable con of a source of high of the apparatus', now to be described, in a neutral condition... v

The particle -laden uid-s'trea'm-may 'be introduced into the electrode 10 inl any desirable mannerz but I lfind it convenient to provide a stationary casing' 15 which `en conducting Huid-stream by the potential of velops the electrode 10 and is provided with a tangentially arranged a downwardly inclined spiral deflector 17, being provided to direct the fluid-stream from the duct` 16 spirally downwardly into the open receiving-.end of the electrode 10,

induction `duct 16,

said end -being guarded, preferably by a said conductor is passed Y through an insulatingtubeQO which passes down through the outlet passage 19.

In operation the particle-laden fluidstream is driven through the induction passage 16 at a high velocit into the inclosing casing 15 being deiected7 by the spiral .deflector 17 downward into theelectrode 10. The electrode 10 is revolved at a speed substantially equal to the angular velocity of the whirling fluid-stream are urged outward by centrifugal action toward the electrode 10. the particles in the Huid stream come into the dischargin 'field of the electrodes 12 and are there c arged with a potential substantially equal-to, and of the same sign as, the electrodes 12, thereupon becoming mutuallyre ellent as Well as reelled by the electrodp orces thus act in the same direction as the centrifugal force to urgethe charged particlesoutward from the center of the mass' -and to the inner face of trode, 10.V The electrode inner face, that of the electrodes 12, and when the the revolving elec- 10 has, upon its charged vparticles approach the inner .face

of said electrode a greater induced charge of the opposite sign, 'i'. e., opposite tothat .ofthe potential of .the dust particles, is produced on the inner face of theV electrode 10,

thus causingthe charged dust particles to be attracted toward and finally stick to the --mner face of the electrode 10. This action wouldgfin course of time produceaconsiderable deposit of particles upon the inner face of the revolving electrode 10, and render the further v( )peraijion either ineiicient At the same Vtime and the particles a charge of a sign opposite to a continuously operating device, I find it advisable to arran ewithiii the electrode 10 a series of brus'es 25 ada ted to contactl with the inner face of the e ectrode l0 and, as the electrode is rotated i'n the direction indicated by the arrow, engage the particles which are sticking to the inner face of the electrode and brush them down to the bottom where theyg ai'e pushed out through suitable discharge openings 26 so as to fall upon the bottom 27` of the inclosing casing 15, being-brushed therefrom by brushes 28 into a discharge hopper 29. The brushes 25 may be `conveniently supported uponthe lower ends of rods 30 suspended from support 31 and, in order to compel the fluid stream to-pass close to the inner wall of the electrode 10, I provide, 'close to the electrodes 12, a baffle plate 32. By this means I have producedan apparatus which `is capable of continuous operation.
