Advanced oxidaiton device with high efficiency using turbulent flow

Abstract

A UV fluid sterilizer which makes it possible to effectively sterilize a fluid which has a low UV transmissivity and an advanced oxidation device with high oxidation efficiency using a turbulent flow. To this end, the UV sterilizer or advanced oxidation device has a spring coil or wrinkled pipe in a spiral shape to bring forth a turbulent or spiral flow in the fluid.

What is claimed is: 
     
         1 . A UV fluid sterilizer comprising a plurality of UV sterilization units, wherein each UV sterilization unit comprises:
 a first crystal tube;   an inner UV lamp installed in the first crystal tube;   a second crystal tube surrounding the first crystal tube; and   a spring coil fixed in a spiral shape at an outer face of the first crystal tube, the coil being disposed between the first and second crystal tubes,   
       wherein fluid to be sterilized flows between and along the first and second crystal tubes. 
     
     
         2 . A UV fluid sterilizer comprising a plurality of UV sterilization units, wherein each UV sterilization unit comprises:
 a crystal tube;   an inner UV lamp installed in the crystal tube;   an outer pipe surrounding the crystal tube; and   and inner wrinkled pipe disposed in a spiral form between the crystal tube and the outer pipe, the inner pipe having a wrinkled shape at a surface thereof,   
       wherein spiral flow of fluid to be sterilized fluid occurs between and along the crystal tube and inner wrinkled pipe. 
     
     
         3 . The sterilizer of  claim 2 , wherein the inner wrinkled pipe is fixed to the outer pipe via a welding. 
     
     
         4 . An advanced oxidation device comprising a plurality of oxidation units, wherein each oxidation unit comprises:
 a first crystal tube;   an inner UV lamp installed in the first crystal tube;   a second crystal tube surrounding the first crystal tube; and   a spring coil fixed in a spiral shape at an outer face of the first crystal tube, the coil being disposed between the first and second crystal tubes,   
       wherein fluid containing materials to be oxidized flows between and along the first and second crystal tubes. 
     
     
         5 . The device of  claim 4 , further comprising a UV transmission contraction film to cover the spring coil to enable a close contact between the spring coil and the first crystal tube. 
     
     
         6 . The device of  claim 4 , further comprising a plurality of external UV lamps disposed outside of the oxidation units. 
     
     
         7 . The device of  claim 4 , wherein the first and/or second crystal tube is replaced with a Teflon tube. 
     
     
         8 . The device of  claim 4 , wherein the UV lamp has a bar shape in parallel with the first crystal tube.
