NOZZLE FOR DISSOLVED AIR FLOATATION SYSTEM

摘要

The present invention relates to a nozzle for a dissolved air flotation apparatus. More particularly, the invention relates to a nozzle for a dissolved air flotation apparatus wherein a microbubble generation quantity is excellent at a low pressure, and microbubbles are uniformly formed in size. The nozzle for a dissolved air flotation apparatus according to one embodiment of the present invention comprises: a housing having a tubular shape and having an inlet formed on one side and having an outlet formed on the other side; a nozzle connector coupled to the inlet and having an inlet conduit formed in a longitudinal direction; and a nozzle body which is formed inside of the housing and which has a collision unit formed in a front end portion so that a fluid flowing through the inlet conduit is switched to flow to a right angle direction and to collide into an inner wall of the housing and which has a plurality of cutout portions formed on a side surface so as to form a side flow path between the inner wall of the housing and which has an ejection groove formed in a lower end portion wherein a collision plate is formed in the ejection groove, and each orifice is formed between the cutout portion and the ejection groove so that a fluid ejected through the orifice collides into the collision plate.
