Abstract

Apparatus for large volume oxygenation of water and the like, such apparatus being connectable to a suitable source of air or oxygen pressure and including distribution means for releasing air under pressure over a relatively large area within a sealed enclosure having at least a portion of the enclosure formed from permeable substance of predetermined porosity to air pressure such that the air or oxygen is released in finely divided form into contact with the water to effect oxygenation thereof.

Claims

1. A device for total immersion in a liquid to release soluble gas in finely divided form for yielding increased dissolution of gas in the liquid, comprising:

enclosure means of generally elongated shape as formed by a bottom panel having oppositely disposed end panels and oppositely disposed side panels sealingly connected thereto, said end panels each including at least one nipple means communicating therethrough;

first and second intermediate panel means each disposed parallel to a respective one of said end panels and being sealingly connected to said side and bottom panels, said intermediate panel means each having a plurality of feed-through orifices communicating therethrough;

first and second cover panels each disposed at opposite end of said bottom panel and being sealingly connected to end and side panels and respective first and second intermediate panel means to define first and second baffle chambers;

porous plate means disposed centrally relative to said first and second cover panels and being connected to the side panels and respective first and second intermediate panel means to define a dispersion chamber in juxtaposition between said first and second baffle chambers;

a plurality of dispersion means each communicating between respective opposite feed-through orifices in said first and second intermediate panel means, each of said dispersion means including a plurality of small holes in communication with said dispersion chamber; and

a source of gas under selected pressure for application to said end panel nipple means for flow through said baffle chambers and dispersion means thereby to be released into said dispersion chamber for passage and fine particulate break-up through said porous plate means into the surrounding solvent liquid.

2. A device as set forth in claim 1 wherein said porous plate means is formed from sintered bronze of predetermined porosity.

3. A device as set forth in claim 1 wherein said porous plate means is formed from porous ceramic material having predetermined permeability to passage of a selected gas such that there is released a plurality of gas bubbles having diameters in the 2 to 5 micron range.

4. An oxygenation device for treatment of liquid which is comprised of a tower means including conduit means receiving liquid under pressure for release at an elevated position atop said tower means, and a plurality of flow shelf means disposed progressively downward along said tower means such that successive ones of said flow shelf means receive said water as it continually flows in generally radial direction from said tower means elevated position, said plural flow shelf means further consisting of an inner flow shelf receiving liquid for radial outward flow and release oVer an outer perimeter and an outer flow shelf receiving water from said inner flow shelf perimeter for radial inward flow and release over an inner circular edge to a next lower inner flow shelf, each of said inner and outer flow shelves including a plurality of series-connected devices each of which comprise:

enclosure means of generally elongated shape as formed by a bottom panel having oppositely disposed end panels and oppositely disposed side panels sealingly connected thereto, said end panels each including at least one nipple means communicating therethrough;

first and second intermediate panel means each disposed parallel to a respective one of said end panels and being sealingly connected to said side and bottom panels, said intermediate panel means each having a plurality of feed-through orifices communicating therethrough;

first and second cover panels each disposed at opposite end of said bottom panel and being sealingly connected to end and side panels and respective first and second intermediate panel means to define first and second baffle chambers;

porous plate means disposed centrally relative to said first and second cover panels and being connected to the side panels and respective first and second intermediate panel means to define a dispersion chamber in juxtaposition between said first and second baffle chambers;

a plurality of dispersion means each communicating between respective opposite feed-through orifices in said first and second intermediate panel means, each of said dispersion means including a plurality of small holes in communication with said dispersion chamber; and

a source of gas under selected pressure for application to said end panel nipple means for flow through said baffle chambers and dispersion means thereby to be released into said dispersion chamber for passage and fine particulate break-up through said porous plate means into the surrounding solvent liquid.

5. A device as set forth in claim 4 wherein said porous plate means is formed from sintered bronze of predetermined porosity.

6. A device as set forth in claim 4 wherein said porous plate is formed from ceramic material having predetermined permeability to passage of oxygen.
