摘要

PURPOSE: A nano bubble generator is provided to effectively remove bad smell substances including in sewage and waste water by using ozone gas. CONSTITUTION: A nano bubble generator comprises: a tubular part(20) soaking into a tank(10) in which fluid is stored; a cylindrical body(30) arranged rotatably by forming linear flow path(L1) by separating from the inner circumference of the tubular part to radial inside; a plurality of screw groove flow paths(L2) of which cross sectional area is gradually changed, and in which middle cross sectional area is smallest, bottom is largest, and top is the middle; a motor(M) driving a motor shaft(31) projected to outside of the tubular part with contacting to the cylindrical body for rotating the cylindrical body; a header part(40) having a plurality of outlets(41) circulated to face each screw groove flow path.
