Abstract
Abstract A well deodorizing apparatus includes a checkvalve which provides unidirectional flow in a pump discharge pipe and a tap upstream from the checkvalve to divert a fraction of the pump discharge and direct it through a venturi orifice. The venturi effect atomizes the diverted water resulting in a pressure decrease in a mixing chamber. Ambient air is drawn into the mixing chamber and intermixed with the atomized water. The resultant mixture of air and water is directed back into the ground water reservoir thereby oxygenating the ground water and deodorizing the well.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
89 words
A device for intermixing gas and liquid from a liquid source to deodorize the liquid, comprised of; valve means for providing a unidirectional flow of said liquid from said liquid source; diverting means for diverting a fraction of the unidirectional flow of said liquid; means for atomizing said diverted fraction of said unidirectional flow of liquid; means for mixing said atomized liquid and said gas; and discharge means for discharging the mixture of said gas and said atomized liquid into said liquid source to deodorize and aerate the liquid.
Claim 2
Independent Claim
89 words
A device for intermixing gas and liquid from a liquid source to deodorize the liquid, comprised of; valve means for providing a unidirectional flow of said liquid from said liquid source; diverting means for diverting a fraction of the unidirectional flow of said liquid; means for atomizing said diverted fraction of said unidirectional flow of liquid; means for mixing said atomized liquid and said gas; and discharge means for discharging the mixture of said gas and said atomized liquid into said liquid source to deodorize and aerate the liquid.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein said valve means is a spring loaded check valve, and said means for atomizing is an orifice.
Claim 4
Dependent Claim
34 words
The apparatus of claim 2 wherein said diverting means is located upstream from said valve means so that fluid is prevented from flowing back through the device when said unidirectional flow of liquid ceases.
Claim 5
Independent Claim
224 words
An apparatus for deodorizing a subterranean well comprised of: pump means for pumping fluid from a fluid reservoir; discharge pipe means for directing fluid away from said pump; valve means for providing unidirectional fluid flow in said discharge pipe; access means located upstream from said valve means for removing some fraction of said unidirectional fluid flow; first pipe means connected to said access means for directing said fraction of said unidirectional flow parallel to and opposite from said unidirectional flow; connection means attached to said first pipe means at a first run end; restricting means, securably attached within said connection means and adjacent to said first pipe means for atomizing the fluid flowing therein; second pipe means, relatively longer than said first pipe means, attached at one end to a branch opening of said connection means and extending beyond said valve means so that when the fluid in said first pipe means is atomized, the resultant pressure decrease will draw ambient air down and through said second pipe means into said connection means, third pipe means connected to a second run end of said connection means for mixing said atomized fluid and said ambient air; and discharge means connected to said third pipe means said for directing the mixture of ambient air and said atomized fluid into said fluid reservoir of said subterranean well.
Claim 6
Independent Claim
224 words
An apparatus for deodorizing a subterranean well comprised of: pump means for pumping fluid from a fluid reservoir; discharge pipe means for directing fluid away from said pump; valve means for providing unidirectional fluid flow in said discharge pipe; access means located upstream from said valve means for removing some fraction of said unidirectional fluid flow; first pipe means connected to said access means for directing said fraction of said unidirectional flow parallel to and opposite from said unidirectional flow; connection means attached to said first pipe means at a first run end; restricting means, securably attached within said connection means and adjacent to said first pipe means for atomizing the fluid flowing therein; second pipe means, relatively longer than said first pipe means, attached at one end to a branch opening of said connection means and extending beyond said valve means so that when the fluid in said first pipe means is atomized, the resultant pressure decrease will draw ambient air down and through said second pipe means into said connection means, third pipe means connected to a second run end of said connection means for mixing said atomized fluid and said ambient air; and discharge means connected to said third pipe means said for directing the mixture of ambient air and said atomized fluid into said fluid reservoir of said subterranean well.

Claim 13
Dependent Claim
154 words
In a system for intermixing liquids and gases in subterranean wells consisting of a pump and discharge pipe for removing liquids in said well, and an aerating device including a first pipe connected to said pump discharge pipe, a venturi to atomize said liquid in said first pipe, a second pipe connected at one end to said first pipe at a point downstream from said venturi and open to the air at the other end to allow passage of gases therethrough, and a third pipe connected downstream from the connection of said first pipe to said second pipe for conducting a mixture of gas and liquid away from said venturi, the improvement comprising means connected to said discharge pipe for diverting a portion of said liquid flowing therein to said first pipe and through said venturi of said aerating device in a direction opposite to the flow of said liquid in said discharge pipe.
Claim 14
Dependent Claim
154 words
In a system for intermixing liquids and gases in subterranean wells consisting of a pump and discharge pipe for removing liquids in said well, and an aerating device including a first pipe connected to said pump discharge pipe, a venturi to atomize said liquid in said first pipe, a second pipe connected at one end to said first pipe at a point downstream from said venturi and open to the air at the other end to allow passage of gases therethrough, and a third pipe connected downstream from the connection of said first pipe to said second pipe for conducting a mixture of gas and liquid away from said venturi, the improvement comprising means connected to said discharge pipe for diverting a portion of said liquid flowing therein to said first pipe and through said venturi of said aerating device in a direction opposite to the flow of said liquid in said discharge pipe.
