  • Patent number: 4957512
    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.
