Abstract
A system and method for automatically blending gases, comprising an input device for receiving predetermined mixed gas concentration data from the user, a plurality of gas inlet valves which allow a plurality of gas flows to enter a homogenizing chamber for mixing the plurality of gas flows into a mixed gas, at least one gas sensor for detecting the concentration of one or more components of the mixed gas and generating at least one output signal representative thereof; and a manager for receiving the at least one output signal and comparing the at least one output signal with the predetermined mixed gas concentration data and in response generating a signal to at least one gas inlet valve to modify the plurality of gas flows to maintain the desired mixed gas concentration.
Claims15
A system for automatically blending gases in a continuous flow manner, comprising:
- (a) an input device for receiving predetermined mixed gas concentration data from the user;
- (b) a plurality of variable gas inlet valves operatively connected to the input device which allow a plurality of gas flows to enter a homogenizing chamber in a continuous flow manner for mixing the plurality of gas flows into a mixed gas;
- (c) at least one gas sensor operatively associated with the homogenizing chamber for detecting the concentration of one or more components of the mixed gas and generating at least one output signal representative thereof;
- and
- (d) a data manager for receiving the at least one output signal and comparing the at least one output signal with the predetermined mixed gas concentration data and in response generating a signal to at least one of the variable gas inlet valves to modify the plurality of gas flows to maintain the predetermined mixed gas concentration in a continuous flow manner.
- 2.The system of claim 1 further comprising a gas sample collector that pulls a sample of the mixed gas prior to the detecting of the concentration of one or more components by the at least one gas sensor.
A method for automatically blending gases in a continuous flow manner, comprising:
- (a) providing an input device for receiving predetermined mixed gas concentration data from the user;
- (b) providing a plurality of variable gas inlet valves operatively connected to the input device which allow a plurality of gas flows to enter a homogenizing chamber in a continuous flow manner for mixing the plurality of gas flows into a mixed gas;
- (c) providing at least one gas sensor operatively associated with the homogenizing chamber for detecting the concentration of one or more components of the mixed gas and generating at least one output signal representative thereof;
- and
- (d) providing a data manager for receiving the at least one output signal and comparing the at least one output signal with the predetermined mixed gas concentration data and in response generating a signal to at least one of the variable gas inlet valves to modify the plurality of gas flows to maintain the predetermined mixed gas concentration in a continuous flow manner.
A method of producing a precise mixture of oxygen and air in a oxygen and air mixed breathing gas in a continuous flow manner, comprising:
- (a) entering a predetermined oxygen content for the oxygen and air mixed breathing gas into an input device;
- (b) supplying a fluid stream of ambient air;
- (c) supplying a fluid stream of oxygen through a variable oxygen inlet valve;
- (d) mixing the air and oxygen streams in a continuous flow manner in a homogenizing chamber to form a mixed breathing gas;
- (e) measuring the oxygen concentration of the mixed breathing gas and generating an output signal representative thereof;
- (f) receiving the output signal and comparing the output signal with the predetermined oxygen content and generating a signal to the variable oxygen inlet valve to modify the fluid stream of oxygen to maintain the predetermined oxygen content in the mixed breathing gas;
- (g) once the predetermined oxygen content is reached, compressing the mixed breathing gas to a high pressure mixed breathing gas;
- and
- (h) transferring the mixed breathing gas into high pressure storage tanks.
A system for automatically blending gases, comprising:
- (a) an input device for receiving predetermined mixed gas concentration data from the user;
- (b) a plurality of gas inlet valves which allow a plurality of gas flows to enter a homogenizing chamber for mixing the plurality of gas flows into a mixed gas;
- (c) at least one gas sensor for detecting the concentration of one or more components of the mixed gas and generating at least one output signal representative thereof;
- (d) a manager for receiving the at least one output signal and comparing the at least one output signal with the predetermined mixed gas concentration data and in response generating a signal to at least one gas inlet valve to modify the plurality of gas flows to maintain the predetermined mixed gas concentration;
- (e) a gas sample collector that pulls a sample of the mixed gas prior to the detecting of the concentration of one or more components by the at least one gas sensor;
- and
- (f) a gas sample return that returns the gas sample after the detecting of the concentration of one or more components by the at least one gas sensor.
