Abstract
In a method for cleaning polluted gas and/or cooling of hot gas, and a device for carrying out the method, the gas is contacted with finely divided liquid. The finely divided liquid is supplied in the form of essentially umbrella-shaped shells or essentially linear curtains, in a regular arrangement, distributed in two or more planes substantially perpendicular to the main flow direction of the gas. The finely divided liquid is supplied such that the gas is alternatively concentrated and spread by the impulse action exerted by the liquid on the gas in directions perpendicular to the main flow direction of the gas. The orthogonal distance between adjacent planes in which finely divided liquid is supplied, is so adjusted that no substantial equalization of the gas flow takes place between the planes. The supply of liquid in adjacent planes is so arranged that it, in a plane located downstream in the flow direction of the gas, takes place where the flowing gas has been concentrated by the impulse action of liquid supplied in the plane located immediately upstream.
