Water largely generates, and leads to cities and towns black and odorous water, not only compromises drinking water safety, also counteracts the benign hair of national economy
Exhibition.Therefore, water environmental problems are increasingly becoming the focus of social concerns.
Currently, the improvement problem of cities and towns black and odorous water is that Dissolved Oxygen in Water is too low, and the indexs such as COD is caused to be difficult to up to standard, water
Matter improvement is bad.The bubble that the modes such as traditional blast aeration generate, diameter is excessive, the residence time is too short in water, increases
Oxygen effect is poor.And the diameter of micro-nano bubble is small, superpower oxygenation and oxidability, multiple pollutant in efficient degradation water, safety,
Reliably, without secondary pollution, it can be widely applied to pollution control, water remediation, aquaculture, crop planting, family's fruit-vegetable clear
Wash, precision component cleaning etc. various fields, have wide social value and market potential.
Currently, micro-nano bubble method for generation both domestic and external mainly has pressure air-dissolving deposition method, electrolysis deposition method, venturi
Fluid jet etc..Wherein, pressure air-dissolving deposition method is using water pump, air compressor machine respectively by the water flow of certain pressure, air indentation pressure
In power dissolving, high-pressure air-water mixture is formed, gas in water is precipitated in the form of nano bubble by decompression suddenly later, but
This method operation and operating cost height, molten gas low efficiency, application range are small.Being electrolysed deposition method is to be powered in water, respectively just
Negative plate generates nano bubble, and the bubble size that this occurring mode generates is controllable, but there are bubbles volumes less, consumption of electrode,
The disadvantages of energy consumption is higher.Venturi fluid jet is to be broken the air pocket in water using high-speed jet and rotational-flow shearing smashing principle
It is broken into micro-nano bubble, application potential is huge due to it has many advantages, such as " compact-sized, easy to operate, flux is big, is not easy to plug "
Greatly, but traditional venturi fluidic device that there are jet directions is single, there is aeration dead angle, aeration uniformity is poor, energy consumption is high, waters
The problems such as service area is small, bubble quantity and size are unable to control.
The drawbacks of to solve traditional venturi fluidic device, the utility model proposes a kind of self-priming micro-nano bubbles of dish
Generating device, can the comprehensive micro-nano bubble of carry out of 360o generation and diffusion, while grazing shot flowing pressure and low operating cost are
The micro-nano bubble of smaller particle size can be obtained, this is that micro-nano bubble generation technique is widely used in necessarily needing for water bodies of rivers and lakes processing
It asks.
