Abstract
A self-balancing, multi-nozzle, low energy aeration head assembly. A process system unit aid for regenerating oxygen depleted aquaculture water biomass tanks, ponds or lagoons. The aeration head may consist of a water inlet 6. The flow from the inlet may split to feed multiple separate nozzles 15 and be aerated by air entering through ports 9.
Description
Technical description
FIG 1 comprises of a new method, derived from CARNOT's shock loss, for entraining high volumes of atmospheric air, at low energy, for difihising oxygen into recycled oxygen depleted Biomass water, without imposing high super saturation levels. The oxygen depleted Biomass water is pumped into Motive Liquid Chamber Body inlet port (1), via recycle Transfer Pump and discharged into the Expansion Chamber via Nozzle (2 & 3), at pressures between 0.40 -1.0 bar gauge. Nozzle (2) diameter is calculated to accept a liquid design flow velocity of l00% value of the high gravity level flow volume. The number of Nozzles (2 & 3) is not limited, and is subject to the Biomass recycle flow volume requirement, which is related to Biomass stock holding load and water volume. The oxygen depleted Biomass water is utilised as the motive energy source of supply, for entraining the atmospheric air through inlet port (4), based on a design factor of 0.5 cubic meters per hour water flow eniraining 20 to 23 standard cubic meters per hour of atmospheric air at 20 degrees Celsius. The actual entrained air volume is subject to the transition area of the Expansion Chamber's total free gas pressure and Nozzle (3) outlet port The delta pressure (Dp) design characteristics and transition area of the liquid feature requirement has been formulated in Nozzle (3) outlet port, when being released into the free gas expansion area of the Expansion Chamber. (ReL FIG 1). The design format has been superimposed at an outlet Dp of 10-15 mm Hg. above 760mm Hg. Barometric pressure. The entrained air becomes encapsulated with the depleted Biomass water in the Nozzle (3) outlet port, prior to expulsion into the Expansion Chamber's transition area. Dunng this cycle the oxygen depleted Biomass flow stream becomes saturated with atmospheric air gases. The expulsion of water at outlet port Nozzle (3) will always remain constant with the recycled oxygen depleted Biomass flow stream. However, the entrained and expelled gas molecules will change according to their surrounding atmospheric conditions. (Reference Dalton's and Heniy's Gas Laws of Pressure and Distribution). The saturated gas expelled water from Nozzle (3) outlet port is pinged onto the inner surface wall of * * *. the Expansion Chamber (Ref. FIG 1). The velocity speed change combined with water agitation * effect produces excited gas molecules, which initiates the formation of the following three-step *S*s. . process for rapidly transfrrnng oxygen into water at a balanced nitrogen ratio.
* : I. Transfer of oxygen in the gas to the gas-liquid interfuice 2. Transfer across the gas-liquid interface 3. Transfer of oxygen away from the interface into the liquid.
Other surplus gas molecules such as carbon dioxide etc. Will follow the nonnal gas law theoiy *:: and will be forced out via vaporisation through vent piping spool (Ref. FIG 1).
The regenerated oxygen depleted aquaculture water gravitationally flows into the associated Biomass holding Tanks, Ponds or Lagoons via the Expansion Chamber's bottom outlet holes.
Although the description has been directed to a Biomass system design arrangement, it can be used to advantage with respect to other liquid system facilities of all shapes and sizes. The form of the invention illustrated on FIG I is a stand alone system and the recycle Transfr Pump is only one suggested source of supply aid.
