Description
Technical field
The utility model is related to a kind of cavitation generator, more particularly to a kind of cavitation hair that two-stage cavitation effect may be implemented
Raw device.
Background technology
" cavitation " is a kind of extremely complex fluid dynamic phenomena, is specific to liquid.Vacuole will appear when shattered to pieces
Instantaneous high temperature and pressure, and there is instantaneous high-speed jet phenomenon, that is to say, that Hydrodynamic cavitation can discharge huge energy, utilize water
The huge energy that power cavitation is discharged may be used as anti-, scale removal of heater heating, sewage disposal, food-pasteurization and pipeline etc.,
To achieve the effect that synergy, energy saving, consumption reduction.
Venturi tube, orifice plate, since it has the design feature of throttling, so when fluid flows through its throttle
When position, fluid flow rate will sharply increase, and simultaneously pressure then strongly reduces, when pressure is less than Liquid saturated vapor, then
Bubble generation is had, as pressure gradually increases, the bubble of generation will gradually crumble and fall, and all one's life of bubble is once this process of going out
It is the cavitation phenomenon generated, huge energy can be released.Cavitation generator is exactly to act as to generate such a role of cavitation,
The energy that cavitation is discharged is generated by using cavitation generator, to meet us in production, needs in life.
Invention content
The purpose of this utility model is to provide a kind of cavitation generators of improved achievable two-stage cavitation, compared to one
As Venturi tube cavitation generator and orifice plate cavitation generator, cavitation effect more preferably, cavitation release energy it is more.
The technical solution of the utility model is：A kind of cavitation generator of achievable two-stage cavitation, mainly composition include
Orifice plate and Venturi tube, it is characterised in that：The cavitation generator is integrated, and appearance is in a tubular form.
Further, the orifice plate is located at close to the side of cavitation device input end, and orifice plate is made of 9 holes.
Further, the Venturi tube is made of input end, converging transition, throat, divergent segment, outlet end, Chinese
The input end of venturi is located at after orifice plate, and the outlet end of outlet end and cavitation device coincides.
The utility model has the beneficial effects that：
1. compared to general fluid power formula cavitation generator Venturi tube and orifice plate, the utility model cavitation generator
It combines both, it can be achieved that two-stage cavitation, is better than the cavitation effect of any single Venturi tube and orifice plate, so as to
Discharge more cavitation energies；
2. the utility model cavitation generator is compact-sized, easily manufactured, use cost is low, high financial profit.

Specific implementation mode
The concrete structure and embodiment of the utility model are further illustrated below in conjunction with attached drawing.
In conjunction with Fig. 1 to 2, the structure composition of the utility model cavitation generator includes input end（1）, orifice plate（2）, venturi
Pipe（8）, outlet end（7）.The cavitation generator is integrated, and appearance is in a tubular form.
The orifice plate（2）Positioned at close to cavitation generator input end（1）Side, orifice plate（2）By 9 holes（3）Composition.
The Venturi tube（8）Positioned at close to cavitation generator outlet end（7）Side, including converging transition（4）, throat
（5）, divergent segment（6）, wherein Venturi tube（8）Input end drop-over orifice plate（2）, outlet end and the cavitation of Venturi tube (8)
The outlet end of generator（7）It coincides.
The course of work of the utility model is as follows：Two-stage cavitation, normal work may be implemented in the utility model cavitation generator
When making, fluid is from input end（1）It flows into, and then flows into orifice plate（2）, due to orifice throttle part（3）Presence, lead to local receipts
Contracting, therefore flow velocity increases, pressure reduction, when pressure is less than the saturated vapour pressure of current liquid, some are dissolved in liquid originally
Gas start to be precipitated, that is, have bubble generation, with the increase of pressure, bubble can gradually crumble and fall again, and all one's life one of bubble goes out
The cavitation phenomenon exactly generated, in orifice plate（2）Realize level-one cavitation in place；Then from orifice plate（2）The fluid of outflow can flow into
Venturi tube（8）, fluid is with converging transition（4）Flow into throat（5）, since caliber is gradually reduced, flow velocity then gradually increases, pressure
It is gradually reduced, bubble generation is had again when less than current liquid saturated vapour pressure, with divergent segment（6）The gradual increasing of caliber
Add, flow velocity is gradually reduced, and pressure gradually increases, and the bubble generated before can gradually crumble and fall again, and all one's life of same bubble is once going out
It is the cavitation phenomenon generated, in Venturi tube（8）Realize that level-one cavitation, cavitation generator entire in this way are just real again in place
Two-stage cavitation is showed.
The basic principles and main features of the utility model have been shown and described above.The utility model is not by above-mentioned implementation
The limitation of example, the principle of the only invention of above embodiments and description description, in the spirit and model for not departing from the utility model
Under the premise of enclosing, the utility model also has various changes and improvements, these inventions and improvement belong to this claimed reality
With in novel range.
