METHOD FOR SUPPLYING. AND CLEANING GAS BY ELECTRICAL ACTION Filed Jan 22, 1932 l/f 4 a o l I I i I 5 l r a INVENTOR l M #a/fl 5, Wm M Patented Nov. 13, 1934' UNITED STATES PATENT OFFICE METHOD FOR SUPPLYING AND CLEANING GAS BY ELECTRICAL ACTION Application January 22, 1932, Serial No. 588,191 InGermany January 19, 193-1 1Claim.
I This invention relates to a method for providing a' supply of clean gas and for electrically cleaning the gas so supplied, and is particularly applicable for the purpose of providing a continual supply of clean air in closed rooms or the like.
In hitherto known methods and apparatus for electric gas cleaning, the gas to be cleaned is usually made to pass through the discharge field by means of a fan or of an otherwise artificially produced draft.
In the following I will now show how in many cases the gas current to be cleaned can, in a rected in this same direction, and results in creat ing convection currents in the surrounding air or gaseous medium, commonly referred to as electric wind, in said direction, which drives the gases to be cleaned in the desired direction through the cleaning apparatus. With an arrangement of that kind, gas velocities of over 1 meter per second can be obtained in the gas cleaning apparatus, without any other means being necessary to increase the draught. .The flow of gas is greatly accelerated, if the discharge electrodes are made to consist of rods or the like and provided with points (pointed parts) directed approximately in the direction of the gas current.
In some cases the flow of gas can be still more increased by placing pervious opposing electrode means, such as wide-meshed wire nettings at a suitable distance beyond the discharging parts of the discharge electrodes, and maintaining a suitable potential diiierence between said discharging parts and said opposing electrode means. These pervious electrode means serve as collecting electrodes and allow the gas to pass through them. This arrangement is particularly advantageous and suitable for small plants serving for cleaning the air in closed rooms or spaces. Furthermore, the presence of these opposing electrode means serves to increase the directional efiect of the electric discharge and the resulting electric wind.
In other cases the electric gas-cleaning apparatusmay advantageously also be so constructed as to have plate-shaped collecting electrodes disposed substantially parallel to the gas stream and, between same, discharge electrodes fitted with discharging points directed approximately in the direction in which the gas current is desired 'to flow. With this arrangement a high velocity is imparted to the gases and besides a good cleaning effect is obtained.
An embodiment of my invention is illustrated by way of example in the drawing affixed hereto. Fig., 1 shows a longitudinal section of the gas cleaning apparatus and Fig. 2 a cross-sectional view of same.
1 indicates the casing of an electric gas-cleaning apparatus fitted with a plurality of plateshaped collecting electrodes 2, between which at suitable distances are suspended the discharge electrodes 3. The discharge electrodes are fastened at their one endto a support 4 mounted on a lead-in insulator 5. This insulator is shown as extending through a partition separating the adjacent chamber '1 from the electrode chamber. In this adjacent chamber '7 is housed a device for the generation of the high-voltage direct current for charging the discharge electrodes. This device consists of a high-voltage transformer 8,
connected up to the current supply 10 by the wires 9.
The one pole of the secondary winding of the transformer as ,well as the casing of the apparatus is grounded. The other pole of the secondary winding is connected to the support 4 of the discharge-electrode system by means of the conductor 11, which passes through the insulator 5. In the ground-connection of the secondary winding is inserted a rectifier, shown in the drawing as an electric valve 12, which rectifies the highvoltage current in such a manner that the discharge-electrode system is charged to a high negative potential.
The, casing 1 of the gas-cleaning apparatus is provided with openings 13 and 14 in its side walls for the admittance of the gases at one end of the electric field, and with a number of openings 15 in the transverse wall at the other end of the electric field, for the gases to escape after being cleaned. The conveyance of the gases to be cleaned, for example of room air, through the discharge field is effected by each of the discharge electrodes 3 being provided with a large number of discharge points (i. e. pointed parts) 16 all so arranged on the discharge electrodes as to point in the direction of the desired flow of gas. The supporting bracket 4 is also provided with a number of such discharging points. Owing to the particular arrangement of the discharging points 16, the so-called electric wind produced at the discharging points blows approximately in the direction in which the gases to be cleaned are to pass through the discharge fields and thus produces a strong draft which drives the gases to be cleaned through the gas-cleaning apparatus in the desired direction of flow, shown by arrows.
blowing it out after the voltage has been switched off.
I claim as my invention:
The method of providing a supply of substantially clean gas which comprises producing an electric discharge in a high potential electric field between a plurality of discharge electrode elements and opposing collecting electrode means and thus creating an electric wind by the action of said electric discharge, said discharge electrode elements and collecting electrode means being so disposed as to cause the electric wind thusproduced throughout said electric field to have a component in one common direction sufiicient to product a bodyflow of gas through said field in said direction, said electric wind constituting the sole means for producing fiow of gas through said electric field, and causing electrical precipitation of suspended particles from said gas on said collecting electrode means by the action of said electric discharge and electric field CARL HAHN.
