The fluid supply pipe with twin venturi effect and aquaculture system equipped with an oxygen supply device for aquaculture organisms applying the same

摘要

A culture system having a pipe for supplying a fluid having a double venturi effect and an oxygen supply device for aquaculture organisms to which the same is applied is provided. The pipe for supplying the fluid having the double venturi effect is composed of first to third parts and is a pipe for supplying the fluid having a double venturi effect. It has a first outlet, wherein the inner diameter of the first inlet is larger than the inner diameter of the first outlet, and has a structure in which the inner diameter gradually decreases from the first inlet to the first outlet; a first portion having a first passage connected to a first outlet portion, a second inlet portion through which the fluid flowing through the first outlet portion is introduced, and a second outlet portion through which the fluid flows out, wherein the second inlet portion includes the first has the same inner diameter as the first outlet so as to be spaced apart from the outlet, the inner diameter of the second inlet is smaller than the inner diameter of the second outlet, a second passage from the outside connected to the second outlet a second portion having a second portion, and a third inlet portion through which the fluid flowing through the second outlet portion is introduced and a third outlet portion through which the fluid flows, wherein the third inlet portion is spaced apart from the second outlet portion to correspond to the second portion and a third portion having the same inner diameter as the second outlet portion, wherein the third inlet portion has a structure smaller than the inner diameter of the third outlet portion.
