CAVITATION DEVICE FOR KILLING MICROORGANISM IN LIQUIDS

摘要

A device for killing microorganisms in liquids, represented by a set of parts mutually interconnected in series and comprising an inflow part (1 ), a pump (2), at least one cavitation tube (3) and an outflow part (5), whose essence lies in the fact that the cavitation tube (3) consisting of a set of mutually connected parts, namely an inflow chamber (31 ), at least one working chamber (33) and an outflow chamber (35), with a transfer between the inflow chamber (31 ) and the working chamber (33) being represented by a confuser (32) and a transfer between the working chamber (33) and the outflow chamber (35) by a diffuser (34), the cavitation tube (3) being designed for the resulting through flow coefficient (KV) of the liquid between an input cross section (311 ) of the inflow chamber (31) and an output cross section (351 ) of the outflow chamber (35) calculated from the following equation: to be at least 15 % lower than the through flow coefficient (KV) of the same liquid in the non- cavitation mode and the value of the peak angle (a) of the diffuser walls (34) to be represented by a value of a > 7°.
