FLUID MIXING APPARATUS

PURPOSE:To mix fluid uniformly and to eliminate the vibration noise by providing a nozzle to a conduit as an inner pipe of double tube structure and injecting the injection fluid into the conduit from the position wherein the tip of the nozzle is projected to the shaft core side other than the inside peripheral wall of the conduit. CONSTITUTION:The kineti energy and the thermal energy incorporated in the steam itself which is dispersed and injected from four sides into the inside of a conduit 10 from nozzles 13a-13d are allowed to collide against main fluid from the radiation directions and the mixing is accelerated with the impact energy of this moment. The mixed fluid of the stream and the main fluid is twisted along the side face of spiral elements 15-20, dispersed uniformly thereby and separated into two at each boundary region of the spiral elements 15-20 and the mixing is accelerated by repeating these division, substitution and superposition. Further, the degree of projection of the above-mentioned nozzles is preferably >=5mm..
