Abstract: A turbine-boosted ultraviolet-radiation sterilizing fluid processor, comprising a quartz sleeve installed inside a tube unit, inside the quartz sleeve being installed an ultraviolet-radiation lamp, at the upper and lower end of the tube unit being respectively a fluid inlet tube and a fluid outlet tube; the invention is characterized in that: at the top of the tube unit and at the lower part of the fluid inlet tube is installed a diversion mechanism to form a fluid pressurizing chamber. When the fluid flows through the fluid inlet tube, into the diversion mechanism for pressurizing, a whirlpool spinning at a high speed is created so that the fluid with sterilizing function is blended properly. The fluid spinning at high speed also flushes the wall of the quartz sleeve thus increases the sterilizing effects and reduces the frequency for maintenance.
