- Still another object of the present invention is to provide an inexpensive fume suppressor which will occupy a minimum of space.
- Another object of the present invention is to provide a fume suppressor which is adapted for use on selfpropelled vehicles.
- a feature of the present invention is its use of a charged aerosol in purifying exhaustgases by entraining minute particles.
- Another feature of the present invention involves the use of a reactant for a component of the fumes in the carrier gas, said reactant being dissolved in the aerosol droplet.
- Still another feature of the present invention is its use "ice of a high DC. voltage source to charge the aerosol particles as they pass through the device.
- a further feature of the present invention is the neutralization of the charged aerosol particles and the entrained pollutants to form a disposable liquid.
- the invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

- FIGURE 2 is a cross-sectional fragmentary view of the aerosol forming and charging section of the present invention.
- FIGURE 3 is a cross-sectional view taken on line 3-3, looking in the direction of the arrows.
- FIGURE 4 is a fragmentary view greatly enlarged taken on line 44 in FIGURE 1, looking in the direction of the arrows.
- FIGURE 5 is a view in longitudinal section of a portion of a second embodiment of the present invention.
- FIGURE 6 is a view in longitudinal section of a portion of a third embodiment of the present invention.
- the invention broadly, according to one form of the invention, contemplates pumping the products of combustion through a conduit containing a charged aerosol of some suitable liquid such as water.
- the charged aerosol is preferably simultaneously formed and charged by a charging electrode, whereupon the fume particles are entrained by the charged aerosol droplets.
- the charged aerosol particles and droplets are then neutralized and coalesce to form larger droplets by the normal process of coagulation within uncharged aerosols.
- the large droplets and their entrained pollutants can then be collected or washed away.
- 10 indicates a conduit such as an automobile exhaust pipe, smoke stack, incinerator chimney or the like.
- the conduit 10 has an inlet end 11 and an outlet end 12, for the passage of the products of combustion in a carrier gas such as air.
- a suitable liquid such as water is led into the conduit 10 by means of a pipe 13 under pressure provided by a pump 14
- the pipe 13 is connected to a reservoir 15 which contains the liquid and which, in the case of an automobile, may be the radiator of the vehicle.
- An array of capillary tubes 16 is disposed within the conduit 10, and is in communication with the liquid within the pipe 13.
- the capillary tubes 16 are similar in size to a small hypodermic needle and preferably have an internal diameter of 0.2 mm. or less.
- the discharged end 17 of the capillary tubes is supported by a thin block 30 held by the walls of the conduit 10.
- a charging electrode 18 is disposed downstream of the ends of the capillary tubes 16, and spaced therefrom as shown in FIGURES 1 and 2.
- the electrode 18 which is in the form of a plurality of spaced vanes 19, is supported by an insulating plug 20 in the conduit 10.
- a DC. voltage source 21 is connected to the charging electrode 18 by means of the lead 22.
- a DC. voltage source of approximately 2,500 volts is suitable for the present invention. All of the elements in the system other than the charging electrode 18 are grounded.
- FIGURE 1 is disposed in one branch of the conduit
- the discharged electrode-18 an electricfield is established between the electrode 1 8 and the ends 17 of the capillary tubes 16.
- the liquid coming from the ends of the capillary tubes 16 is thus discharged into the conduit 10 in the form of a charged aerosol of minute liquid droplets 23,
- the droplets 23 have been marked with a plus sign to indicate a positive charge impressed thereon; but may be charged either positively or negatively.
- the droplets 23 are combined with the products of combustion 24, moving through the conduit 10.
- fume particles carried by the exhaust gas 24 are entrained by the charged aerosol droplets in the charging region between the capillary array 16 and the electrode 18.
- the liquid droplets consisting of the charged aerosol and the fume particles traverse the electrode 18 as indicated at 23', in FIGURE 1.
- a collector screen 25 in the form of a lattice is disposed acrossthe conduit 10 downstream of the electrode 18 aS shown in FIGURE 1.
- the collector screen is made of electrically conductive material and provided with a plurality of needle-like points 26 which extend in the direction of the electrode 18 and serve to discharge the droplets 23.
- the droplets 23, which are now neutral pass through the screen 25 and coalesce to form larger droplets 27 by the normal processes of coagulation within an uncharged aerosol.
- the larger droplets containing the fume particles therein emerge from the exit end 12 of the conduit 10 and may be collected or allowed to fall harmlessly to the ground as though they were rain drops.
- the fume suppressor is used in conjunction with the exhaust of an internal combustion engine it may be desirable to inject a small amount of a peroxide from a reservoir 28 into the pipe 13 so that it is mixed with the liquid therein.
- the peroxide will react with the carbon monoxide in the exhaust gases to form carbon dioxide and thereby eliminate the harmful fumes.
- the pump 14 should be connected directly to the engine in any suitable manner whereby increase in engine speed will increase the speed of the pump to force an increased amount of liquid into the conduit 10 so that a sufficient amount of charged aerosol is present within the conduit to entrain substantially all of the combustion products passing therethrough.
- FIGURE 5 there is shown another form of fume suppressor made in accordance with the present invention in which the charged aerosol droplets 24, formed inthe manner set forth in connection with FIG- .URES 1-4, and with the particles of combustion entrained therein are picked up by a collector electrode 32 in the form of a metal sleeve carried within the conduit 10 and separated therefrom by a dielectric layer 31.
- the collector electrode is maintained at a negative voltage if the droplets are positively charged and at a positive voltage if the droplets are negatively charged.
- the droplets are attracted to the collector electrode 32 and coalesce thereon to form a liquid film 27 which will flow out or be blown out of the exit end 12 of the conduit 10,
- FIGURE 6 there is shown still another embodiment of the present invention in which the conduit 10 is forked as indicated at 28 to provide two passageways for the products ofcombustion.

- a positive D.C. voltage is applied to the charging electrode 18 and a negative DC. voltage applied to the electrode 18*.
- the charged aerosol droplets 23 and 23 that emerge from the electrodes 18, 18 respectively are oppositely charged.
- the conduit might constitute a vertical chimney or vent without departing from the spirit 'of the invention.
- some suitable means for leading the large droplets 27 out of the chimney may be supplied, such means being well known within the art and forming no part of the present invention.
- the present invention may also be used to detoxify or neutralize chemical wastes by'mixing well known reactants with the liquid of the aerosol.
- fumes containing sulphuric acid or sulphurus acid can be reacted with sodium hydroxide dissolved in the charged droplets to render such fumes harmless.
- Alkaline type fumes can be treated with hydrochloric acid dissolved in the charged droplets, Nitric oxide (NO) can be absorbed with a solution of alkaline sulfite or dithionate.
