<P>PROBLEM TO BE SOLVED: To provide a gas-liquid contact/diffusion apparatus, in which energy saving, space saving and a maintenance-free operation can be achieved, submicron particles in a gas can be collected easily and the gas can be absorbed simultaneously, and the scale-up of which is facilitated and which has high efficiency. <P>SOLUTION: There are a gas-liquid contact method and the gas-liquid contact apparatus, in each of which the gas is contacted/mixed with a liquid. The gas-liquid contact apparatus 1 is configured so that in the upstream part of a cylindrical vessel 2, a static fluid mixer having a spiral blade therein is disposed on a first gas-liquid contact part 3, and in the downstream part of the first gas-liquid contact part 3, a static fluid mixer having a spiral blade therein is disposed on a second gas-liquid contact part 4. Sprinkler nozzles 22, 23 are disposed in the upper parts of the first and second gas-liquid contact parts 3, 4. The pressurized or depressurized gas containing different kinds of substances is introduced from the upstream part of the vessel 2, and the liquid is supplied/sprayed from the sprinkler nozzles 22, 23 to make the gas flow through the first gas-liquid contact part 3 at 20-150 m/s gas velocity and through the second gas-liquid contact part 4 at 0.5-20 m/s superficial gas velocity. <P>COPYRIGHT: (C)2013,JPO&INPIT |
