Abstract: A method of cleaning gas from solid and gaseous matter is accomplished by a two-stage scrubbing of a gas flow with a liquid. For the first-stage scrubbing, the gas is admitted at a velocity of 30-40 m/s and is cooled in the course of scrubbing to the temperature of its adiabatic saturation. For the second-stage scrubbing, a flow of gas/liquid mixture is admitted at a velocity of 50-70 m/s, being then cooled at 40.degree.-50.degree. C. Electric precipitation of unwanted matter takes place at a field strength of 5-9 kV/cm. The velocity of the gas/liquid flow through the electric field is 3-4 m/s, and the cooling effect at this stage reduces the temperature of the gas/liquid mixture to 20.degree.-25.degree. C.The apparatus which materializes the method of cleaning gases comprises means of scrubbing the gas, which are successively interconnected by a fluid flow and consist of a first means in the form of a scrubbing tower and a second means in the form of a Venturi tube, and at least one electric precipitator.

Abstract: An apparatus for removing solid particles from internal combustion engine exhaust gases is proposed, in which the flow of exhaust gas travels at a high speed of more than 2.5 m/sec through an elongated tube (4), in which a corona discharge takes place from a coaxial spray disk/electrode arrangement toward the wall of the tube. Inside the tube, the soot particles are agglomerated to form larger particles, which are not deposited on the walls because of the high flow speed, which then carries them to a centrifugal precipitator, leading away from which are a tube carrying scrubbed exhaust gas and an outlet having a small quantity of exhaust gas highly enriched with soot. This soot-enriched flow of exhaust gas can advantageously be recirculated to the intake side of the associated engine for afterburning.

Abstract: Discharge electrodes for use in electrostatic precipitators. In preferred form a discharge electrode is formed of a pair of body elements arranged in a partially overlapping relationship. The overlapping structure is such that a longitudinally extending support portion is formed in the lateral intermediate portion of the electrode. To each side of the support portion a web portion is formed which includes one of the body elements extending the full lateral extent of the web portion and the other body element extending only part of the lateral extent of the web portion. The body element which extends on each side of the support the full lateral extent of the web portion, also extends to form the corona discharge portion on that lateral side of the electrode.

Abstract: An electrostatic precipitator for extracting particles and other contaminants from a gaseous stream to be purified, the contaminants being ionized by means of a discharge electrode structure which includes a column of dielectric material whose central axis is coincident with the axis of a collector tube within which the column is disposed. The column has a cross-sectional geometry that defines a circular series of longitudinally-extending niches. Supported between the ends of the column is a circular array of fine gauge wires each of which is suspended with a respective niche. A high voltage is impressed between the wires in the array and the inner surface of the collector tube to create an electrostatic field in the annular region between the discharge electrode structure and the tube to ionize contaminants in the gaseous stream passing therethrough. The surfaces of the niches acquire bound electrostatic charges whereby the voltage gradient established between the discharge electrode structure and the tube is substantially uniform, thereby attaining optimum collecting and ionization conditions.

Abstract: An electrostatic precipitator having an inner electrode extending along the axis of a tubular outer electrode. The inner electrode includes an elongated support electrode connected to a disc shaped discharge electrode having a transverse dimension larger than the transverse dimension of the support electrode. A high potential applied between the outer electrode and the support and discharge electrodes produces a relatively thin, radially and circumferentially uniform electrostatic field between the discharge electrode and the outer electrode, and a non-corona producing electric field between the support electrode and the outer electrode. A particle entrained gas is directed into the outer electrode at the discharge electrode end. The particles are charged by the thin, intense electrostatic field adjacent the discharge electrode, and are subsequently accelerated toward the outer electrode by the electric field extending between the support electrode and the outer electrode. The particles are then deposited on the walls of the outer electrode where they are removed by a film of liquid flowing along the inner surface of the outer electrode. In an alternate embodiment a plurality of discharge electrodes of either uniform or varying transverse dimensions are spaced apart along the support electrode to provide multiple charging and collection states through which the gas sequentially passes.
