According to the present invention, a fluid crashing apparatus includes: a chamber main body where a chamber is formed; a supply pipe for supplying a high pressure fluid to the chamber; an injection nozzle which is installed between the chamber and the supply pipe, and increases the velocity of the supplied high pressure fluid; and a discharge part which is installed and supported on a lower part of the chamber main body, and discharges the fluid including atomized particles. The injection nozzle comprises: a nozzle main body which has a through-hole formed along a length direction inside, and has one end linked to an ejection hole, and has a ring-shaped concave groove with a flow passage guide hole corresponding to the supply pipe on a circumference; and a needle main body having a needle which is inserted into the through-hole through the other end of the nozzle main body, and has a decreasing diameter as going to an end. By the same, the fluid crashing apparatus can minimize internal blockage of the injection nozzle, and can reduce maintenance time by a method of recombining the needle main body without replacing the nozzle main body. |
