Technical field
The present invention relates to a kind of device of on-line control cavitation effect, belong to fluid reaction engineering device technique field.
Background technology
Cavitation phenomenon is that pressure declines when fluid flows through a flow restriction zones (such as orifice plate, Venturi tube etc.), works as pressure drop
During to liquid saturated vapor pressure at such a temperature, liquid begins to boil off and produces a large amount of cavitation steam bubbles, and cavitation steam bubble is with stream
Body is further during flowing, and runner expands, and fluid pressure rises, and cavitation steam bubble is under the pressure effect of surrounding, and volume is anxious
Play is reduced until crumble and fall, and can produce high temperature and high pressure at its moment steam bubble center of crumbling and fall, and with strong shock wave and micro- penetrates
Stream, strong shock wave and microjet can form strong mechanical agitation effect between interface, strengthen two-phase mixtures.Due to
The cavitation steam bubble that cavitation is formed does mass motion together with liquid, can form one than more uniform cavitation interior in a big way
Strengthen field, this is the advantage place of its industrial applications.
The research that current cavitation technique strengthens means as course of reaction is main in wastewater treatment, food, field of medicaments；One
As judge whether fluid there occurs Cavitation with the cavitation value of cavitation zone, formula is as follows, δ c=2（P-PV）/ (ρ V2),
Wherein：δ c are cavitation value, and P is liquid local static pressure, and Pv is the vapour pressure of liquid, and ρ is the density of liquid, and V is the speed of liquid
Rate.It has been generally acknowledged that δ c ＜ 1 have, cavitation generation is possible, and the smaller Cavitations of cavitation value δ c are more violent.The generation of cavitation phenomenon certainly will
Bring the massive losses of Fluid pressure before and after cavitation, device power consumption increase.The acid adding reaction of food service industry vegetable oil is every
Produce the one-level cavitation pressure loss and reach 20 ~ 30bar.
Cavitation generating means core parts are generally static orifice plate both at home and abroad at present, it is impossible to which parameter occurs for on-line control cavitation,
The conditions such as flow, initial static pressure and physical properties of fluids state so to treatment fluid require very high, vary slightly needs offline right
AND DEWATERING FOR ORIFICE STRUCTURE and series are adjusted；Otherwise for the demand of the extent of cavitation of different material, it is impossible to which cavitation occurs for on-line tuning
Series, cause unnecessary power consumption.
