Described oxygen concentration analyser, baroceptor, air delivery valve 207, oxygen omnibus bar 208, supercharger 210 are electrically connected to this controller 10 respectively.
The oxygen concentration analyser detects the oxygen concentration in tank 201 for Real-Time Monitoring, and sends the oxygen concentration simulating signal to controller 10.
Baroceptor is for the atmospheric pressure value in Real-Time Monitoring oxygen gas-holder 203, and feedback pressure signal is to controller 10.In specific implementation process, for improving the stability of system, also be provided with the baroceptor (not shown) be electrically connected to controller 10 on described detection tank 201, this baroceptor is spare part; When the baroceptor on oxygen gas-holder 203 damages, the baroceptor detected on tank 201 can be worked voluntarily, to guarantee system stable operation.Simultaneously; also be provided with air pressure overload protection valve (not shown) on described oxygen gas-holder 203; this air pressure overload protection valve is electrically connected to this controller 10; atmospheric pressure value in oxygen gas-holder 203 is during higher than safety value; controller 10 sends opening signal and opens this air pressure overload protection valve; reduce the air pressure in oxygen gas-holder 203, prevent the generation of security incident.
What this system provided is medical oxygen source, for improving the degree of cleaning of oxygen source, between described oxygen gas-holder 203 and air delivery valve 207, is provided with sterilizing filter 214.
When the first oxygen generation system, the second oxygen generation system work, air in atmosphere is respectively after the first air compressor 401, the second air compressor 402 compressions, after removing most of water or mist of oil by grade one filter 301, enter respectively again the first cooling driers 501, the second cooling driers 502 is cooling, make the vaporous water molecule in pressurized air further be liquefied as liquid state water, after the first cooling driers 501, the second cooling driers 502 self dewater, the remaining micro-moisture of air is further removed airborne moisture through second, third grade of strainer 302,303.Water content very low (approximate dry air) in air now, air after treatment enters air storage tank 209 for the first oxygenerator 601, the second oxygenerator 602.
The first oxygenerator 601, the second oxygenerator 602 are made respectively oxygen, and by pipeline by oxygen delivery to detecting tank 201 and oxygen gas-holder 203, the oxygen concentration analyser detected in tank 201 carries out Real-Time Monitoring to the concentration of oxygen, and sends the oxygen concentration simulating signal to controller 10.
Controller 10 judges according to the oxygen concentration simulating signal received whether the concentration of oxygen reaches the oxygen concentration set(ting)value in this controller 10, and for example, this oxygen concentration set(ting)value is set as 93.2%.
As the concentration of oxygen reaches oxygen concentration set(ting)value 93.2%, controller 10 output opening signals are to the air delivery valve 207 arranged on the aspirating pipeline 206 of oxygen gas-holder 203, air delivery valve 207 is opened, and the oxygen in oxygen gas-holder 203 is delivered to oxygen through aspirating pipeline 206 and removes pipe network 205.
As the concentration of oxygen does not reach oxygen concentration set(ting)value 93.2%, controller 10 output closure signal, opening signal are respectively to the air delivery valve 207 and oxygen omnibus bar 208 that arrange on the aspirating pipeline 206 of oxygen gas-holder 203; Air delivery valve 207 is closed, and oxygen gas-holder 203 stops removing pipe network 205 air feed to oxygen; And oxygen omnibus bar 208 is opened, by oxygen omnibus bar 208, to oxygen, go pipe network 205 to provide concentration oxygen up to standard.
Use oxygen safety for what guarantee that oxygen removes pipe network 205, by oxygen omnibus bar 208 air feed the time, oxygen omnibus bar 208 Real-time Feedback air pressure signals are to controller 10; Atmospheric pressure value in oxygen omnibus bar 208 is during lower than threshold value, controller 10 output shutdown signals with opening signal respectively to oxygen omnibus bar 208 and air delivery valve 207; Oxygen omnibus bar 208 is closed, and air delivery valve 207 is opened, and oxygen gas-holder 203 normally removes pipe network 205 air feed to oxygen, until the atmospheric pressure value in oxygen omnibus bar 208 is higher than threshold value; Then, then by controller 10 output closure signal with opening signal respectively to air delivery valve 207 and oxygen omnibus bar 208, air delivery valve 207 is closed, oxygen omnibus bar 208 is reworked.
When air delivery valve 207 is closed, oxygen gas-holder 203 raises with the air pressure detected in tank 201, and by its atmospheric pressure value of baroceptor Real-Time Monitoring on oxygen gas-holder 203; Air pressure raises, and in air, nitrogen partial pressure increases, and the molecular sieve in oxygenerator is easier to absorb nitrogen, the corresponding rising of the concentration of the oxygen of preparing;
As oxygen concentration reaches oxygen concentration set(ting)value 93.2%, controller 10 output opening signals, shutdown signal are respectively to air delivery valve 207 and oxygen omnibus bar 208; Air delivery valve 207 is opened, and the normal air feed of oxygen gas-holder to oxygen removes pipe network 205; And oxygen omnibus bar 208 is closed;
As the air pressure at oxygen gas-holder 203 is increased to first threshold, the HVT high voltage threshold that this first threshold is oxygen gas-holder 203, and when oxygen concentration does not return to oxygen concentration set(ting)value 93.2% yet, controller 10 output opening signals are to the supercharger 210 of being located between oxygen gas-holder 203 and air storage tank 209, supercharger 210 work, the gas extraction that oxygen concentration in oxygen gas-holder 203 is below standard is to air storage tank 209, and is back to the first oxygenerator 601, the second oxygenerator 602 oxygen again; Because the concentration of oxygen the gas that is back to oxygenerator from air storage tank 209 is higher, after the first oxygenerator 601, the second oxygenerator 602 oxygen again, the concentration of the oxygen of output can be gone up fast to oxygen concentration set(ting)value 93.2%.When supercharger 210 work, when the air pressure of oxygen gas-holder 203 is reduced to Second Threshold, the low pressure threshold that this Second Threshold is oxygen gas-holder 203, controller 10 output shutdown signals are to supercharger 210, supercharger 210 quits work, when the air pressure of oxygen gas-holder 203 is increased to first threshold, supercharger is reworked, until the concentration of the oxygen of the first oxygenerator 601, the second oxygenerator 602 preparations reaches oxygen concentration set(ting)value 93.2%.
The foregoing is only preferred embodiment of the present utility model, not be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and all by the scope of the utility model claims, is covered.
