An open contact reactor is in the form of a tank (1), in which a plurality of spray nozzles (2) for spraying finely divided liquid are arranged and through which a gas is to be conducted in a main gas flow direction (P) in order to be contacted with the finely divided liquid, the spray nozzles (2) being arranged on different nozzle levels (L1, L2, L3), which are spaced apart in the main gas flow direction. The nozzles (2) on each level are substantially uniformly distributed over the cross-section of the tank. A nozzle assembly (4) for spraying finely divided liquid is arranged at the circumference of the tank (1) on at least one level along the main gas flow direction (P). Each nozzle assembly consists of an annular nozzle member (4), which extends along the circumference of the tank (1) on the respective levels and has a circumferential mouth gap (8) which is directed into the tank (1). |
