Abstract

A nozzle for the atomization of a liquid containing a suspension of solid particles with the aid of an atomizing gas, e.g. for use in plants for the removal of sulfur dioxide from flue gases according to the dry scrubbing method. To avoid clogging and non-uniform liquid distribution, the nozzle (1) consists of a symmetric central body (2) with a cavity (3) into which a central liquid main (4) feeds, between three and ten mist orifices (5) being arranged symmetrically around the central body, consisting of tubular housings (6) whose longitudinal axes (7) form an angle (v) of between 20 and 90 DEG with the longitudinal axis (8) of the central body. Each mist office has a circular outlet opening (9) with a diameter of between 1 and 10 mm and with a radially symmetric atomizing zone (11) that is supplied individually with atomizing gas from a tubular gas orifice (12) installed upstream of the outlet opening (9).
