Specific embodiment
The present invention is described further below with reference to embodiment:
The invention discloses a kind of underwater nano-bubble generating apparatus based on variable density method, wherein includes: a transformation
Tracheae protrudes into a mixing wastewater with air room, and transformation intratracheally fills aeration stone, and aeration stone protrudes into the water of mixing wastewater with air room；Mixing wastewater with air
One immersible pump of room outlet connection.It is smaller that the present invention first passes through the bubble that transformation tracheae generates aeration stone mixing, then by latent
Water pump further cuts bubble, guarantees that the nano bubble generated in mixing wastewater with air is less than by both modes
200nm does not occur the misty or obvious bubble of the water surface.
Further, transformation tracheae includes: a tube body, and tube body passes through a heating device.Specifically, heating device can be set
Heating temperature is set from 50-200 DEG C, after gas enters tube body heating, gas is expanded, and connects when gas enters aeration stone with water
Touching, generates bubble, bubble makes Air Bubble Size become smaller naturally after being cooled down rapidly by water flow after being mixed.
Further, transformation tracheae includes: primary air inlet pipe, secondary air inlet pipe, and the diameter of secondary air inlet pipe is greater than primary
The diameter of air inlet pipe.Specifically, primary air inlet pipe is arranged according to 10-20mm diameter, the diameter of secondary air inlet pipe is according to 5-10 times
In primary air inlet pipe be configured.Aeration stone is each filled in two air inlet pipe.The intratracheal aeration stone of transformation and water flow contact, with
Just when water flow passes through aeration stone, microbubble is generated.In specific implementation process of the present invention, the structure is not mainly for passing through change
The gas (such as gas of the unsuitable excessive temperature such as ozone) that warm therapy is realized can realize pressure by tracheae cross-section variation
