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: The apparatus consists of a hollow cylindrical case arranged at an angle to the horizontal axis of its rotation. Disposed in a space inside the case are coils each bent into a helix of suitable shape, arranged coaxially relative to other coils and connected to manifolds which are attached to an internal wall of the case, each with only one of its ends and are connected to a space between the walls of the case passing wherethrough is a heat carrier. The points where the coils are connected to the manifolds are separated from the internal wall of the case by a distance anywhere between 1/3 and 1/2 of the internal diameter of the case of the drier.
