DOUBLE INJECTION NOZZLE FOR IMPROVING INJECTION DISTANCE OF HIGH VISCOSTY FLUID

摘要

The present invention relates to a double injection nozzle for improving the injection distance of a high-viscosity fluid, which can reduce the viscosity of a high-viscosity fluid by heating a high-viscosity fluid which flows inside the nozzle, and improve the injection distance of the high-viscosity fluid by mixing the same with another fluid during the injection. The injection nozzle comprises: a first nozzle which forms a first fluid path; a second nozzle which encloses the circumferential surface of the first nozzle to form a second fluid path between the same and the circumferential surface of the first nozzle; and a heating part which is mounted in either the first nozzle or the second nozzle and reduces the viscosity of a high-viscosity fluid by heating the high-viscosity fluid which flows through any one from the first fluid path and the second fluid path. A low-viscosity fluid flows through the other path of the first fluid path and the second fluid path, and the high-viscosity fluid which is injected from either the first fluid path or the second fluid path in a state of being heated is mixed with the low-viscosity fluid which is injected through the other path from the first fluid path and the second fluid path, thereby improving the injection distance.
