Cavitator-system i.e. hydrodynamic cavitation mixer, flow rate adjustment method, involves supplying back partial flow of fluid from end of cavitator-section into circular flow via return passage during falling of minimum pressure decrease

摘要

#CMT# #/CMT# The method involves providing a cavitator-system with a cavitator-section (1) having parallely connected cavitators (1b), and determining minimum pressure decrease by the cavitator-section under consideration of characteristics e.g. temperature, of a fluid to be processed. A partial flow of fluid is supplied back from an end of the cavitator-section into a circular flow via a return passage (3) before beginning of the cavitator-section during falling of the pressure decrease. #CMT# : #/CMT# An independent claim is also included for a cavitator-system having a cavitator-section. #CMT#USE : #/CMT# Method for flow rate adjustment of a cavitator-system i.e. mixer (claimed) such as hydrodynamic cavitation mixer. #CMT#ADVANTAGE : #/CMT# The partial flow is supplied back from the end of the cavitator-section into the circular flow via the return passage before beginning of the cavitator-section during falling of the minimum pressure decrease, so that the pressure decrease is correlated with flow speed at obstacle-bodies and in confined areas of the cavitators to control the cavitator based on the pressure decrease, thus automatically adjusting change of the operating conditions such as varying flow rates and product parameter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a cavitator system. 1 : Cavitator-section 1b : Cavitators 3 : Return passage 4 : Pump 5 : Mixing point 6 : Controller 7 : Adjusting valve.
