PURPOSE:To perform effectively the dispersion of oxidable bleachable fluid into slurry by providing one or plural nozzles to the front end face of a nozzle part wherein the front end face is perforated and the different directions are directed by the nozzles and also correlating a pump for press-feeding fluid to the rear end of a tubular hollow beam. CONSTITUTION:The gas cutting part X-X of a conduit 1 is joined to the gas cutting part corresponding thereto via a flange 15. Then, the rear end of a hollow beam 2 is directly joined to a pump for press-feeding the oxidable bleachable liquid and also connected with a rotary motor rotating the hollow beam 2. Therefore, when the pulp slurry is press-fed in the direction of the arrowheads through the inside of the conduit 1, the oxidable bleachable fluid, for example, gaseous oxygen is injected under the strong pressure from the plural nozzles 7, 8, 9 which are provided to the end face of a rotary nozzle part 5 and directed to the different directions and thereby gaseous oxygen is uniformly dispersed into the pulp slurry and the required dispersion effect can be obtained. |
