DEVICE FOR TREATMENT OF LIQUID BY ULTRA-VIOLET RADIATION Russian patent published in 2001 - IPC

FIELD: disinfection and sterilization of liquids (badly turbid media) inclusive) by means of ultra-violet radiation of bactericidal range; submersible multi-lamp closed systems. SUBSTANCE: has cylinder whose base has holes; it is also provided with inlet and outlet branch pipes and inner cylinder with stiffeners. Ultra-violet lamps are placed in covers made from material transparent to ultra-violet radiation; they are located in circular clearance between envelopes in parallel with their generatrices; they are received by holes in base of outer envelope. Lamps in circular clearance are arranged over concentric circles; inlet and outlet branch pipes are located coaxially relative to envelopes and units for forming flow are located on outer of inner envelope; they are made in form of straight and/or concave blades turned at angle relative to guide. EFFECT: enhanced efficiency; possibility of processing badly turbid liquids at high flow rate. 5 cl, 2 dwg
