Description
Technical field
The present invention relates to aquaculture field, be specially a kind of two-forty water body oxygenate apparatus.
Background technology
High speed oxygenation is the problem perplexing many aquaculture families always, as madai etc. needs the fish of high dissolved oxygen environment to be difficult to find good oxygenation way in breeding process, need a large amount of oxygen replenishing equipments to run simultaneously, and the growth of fish of noise extreme influence.In addition, the fish such as duckbilled fish need great dissolved oxygen to meet living necessities in transportation, because anoxic causes a large amount of fish body dead more than traditional air pump and airbag transport, also limit transportation range.
Tradition bubble diameter is at 0.5mm-2mm, rise rapidly in water, vanishing immediately after the arrival water surface disappears, and slow for the microbubble rate of climb in water of diameter below 50 μm, specific surface area is large, and therefore the speed of gas-liquid mass transfer is far above traditional large-size bubbles.In recent years, micron bubble is not only widely used in the industrial circles such as air supporting, oxygenation aeration, beverage deoxidation, is also more and more applied to the civil areas such as medical treatment, beauty treatment, bathing.
Due to the various advantages of micron bubble, increasing people begin one's study micron bubble produce mechanism and micron bubble generate equipment.Existing micron bubble generating means mainly contains supersonic oscillations formula, mechanical shearing type and hydraulic shear formula etc.Wherein, because sonic oscillation formula and mechanical shearing type need the machinery of addition ultrasound wave generating device or complexity to form, therefore apply less, current micron bubble generating means adopts hydraulic shear formula mostly, by special design, realize unique flow field, by the hydraulic shear effect in flow field, the large-size bubbles in fluid is broken for micron bubble.As patent CN 101565230 B, describe micron bubble generating means and cyclone thereof, the bubble breaking discharged by low-pressure area by the hydraulic shear effect of rotating flow becomes micron bubble, and the equipment close with it also has patent JP JP 2003-126665.
Existing hydraulic shear declines a meter bubble generator, the negative pressure of the low-pressure area all relying on rotational flow field or Venturi tube structure to be formed introduces gas (or directly passing into compressed air), be discharged in fluid by molten gas with the form of bubble by higher-pressure region again, the hydraulic shear effect finally by rotational flow field carries out fragmentation to large-size bubbles.The said equipment can produce the microbubble of some, but number of bubbles in unit volume is less, generally 10
5individual/below L, is difficult to meet the keeping demand under the higher environment of unit oxygen demand.
