Oxygen workflow explanation processed:
The present invention is after opening oxygen generation system, and oxygen generation system first carries out atmospheric pressure identification, and (height above sea level of working environment is sentenced It is disconnected).This identifies that work is completed by control unit and pressure sensing cell, and control unit is in control air compression unit work While start timing, and real-time detecting system pressure value (oxygen absorbing unit operating pressure processed).For the system pressure for guaranteeing detection Force value is accurate enough, and the sample frequency of pressure value cannot be too slow, and sample frequency, which must assure that, can effectively identify that pressure becomes Change, meanwhile, for the consistency for reducing sampling error, increasing product, sampled pressure value need to pass through the disposal of gentle filter.When control is single When member judges that system pressure value after processing reaches setup pressure value, the time of air compression unit work is calculated, no The same working time corresponds to different external pressure force value (corresponding to different height above sea level).
The atmospheric pressure of equipment working environment in the present invention, the i.e. approximation to function of height above sea level and timing time are following passes System:
Wherein, H is height above sea level, and T is timing time, and a, b are the coefficient value of function.The coefficient value of above-mentioned function is to pass through The experiment of simulated high altitude environment or calibration test on the spot obtain the functional relation that data determine.The coefficient value of above-mentioned function is by air The joint effect of compression unit capacity and oxygen absorbing unit adsorption capacity processed and volume of gas storage tank, therefore when air compression is single When first gas supply capacity is different, oxygen absorbing unit adsorption capacity difference processed designs volume difference with air accumulator, the coefficient of above-mentioned function Value all can be different.
The present invention, be to oxygen absorbing unit processed into before normal oxygen process processed after completing atmospheric pressure identification Running parameter (mainly service life and evacuation time) is adjusted, to guarantee the air total amount entered in oxygen absorbing unit processed The oxygen of corresponding amount is produced enough, and guarantees that operating pressure is suitable for the operating pressure of interior molecules sieve absorption nitrogen.It is specific to adjust Adjusting method is as follows:
Control unit external pressure force value according to obtained in above-mentioned atmospheric pressure identification step (height above sea level angle value), is adopted Segment processing is carried out to different height above sea levels with software program, different height above sea level sections corresponds to different control parameters, and control is single Member identifies which height above sea level section is equipment be located at using software checking book method first, then carries out assignment to control parameter according to height above sea level section Adjustment.Control parameter includes service life and the denitrogen time of oxygen absorbing unit processed, to guarantee that pressure is suitable, and is provided Air capacity produce corresponding oxygen enough, when denitrogen, can sufficiently parse nitrogen.
Assuming that oxygen generation system of the invention sets operating altitude as 0-4000m, the relationship of this height above sea level and atmospheric pressure is herein It is approximately linear relationship in range, can is that a height above sea level section divides with every increase 800m to height above sea level.Sentence in measurement When disconnected outside atmospheric pressure, different altitude height, the time T that system pressure reaches preset value space-time air pressure contracting cell operation can not Together.Assuming that equipment works in height above sea level 300m, height above sea level 3000m and tri- height above sea levels of height above sea level 3800m, then control unit detects Time can be respectively T1, T2 and T3 (T1 < T2 < T3), control unit can provide according to built-in software program different respectively Oxygen absorbing unit control parameter (referring to following table) processed: service life G1, G2 and G3 and exhaust (denitrogen) time P1, P2 and P3. Wherein the relationship of T1, T2 and T3 are T1 < T2 < T3, which can control oxygen absorbing unit parameter processed: service life relationship is G1 < G2 < G3, denitrogen time relationship are P1 < P2 < P3.
For system of the invention, one group of suitable data is as follows:
Height above sea level (unit: rice) 300 3000 3800
Detection time (unit: second) 8.0 12.5 17.4
Service life (unit: second) 5.6 8.4 11.0
Evacuation time (unit: second) 5 7 9
According to above-mentioned data, in the oxygen generation system equally configured, the functional relation of height above sea level and timing time is obtained Are as follows:
Oxygen absorbing unit processed of the invention is by two identical adsorption tower groups at when adsorption tower gas supply thereto When, the adsorption tower absorption nitrogen oxygen producing, while another adsorption tower carries out denitrogen so as to internal regenerating molecular sieve.There is electricity Magnet valve is connected at the air inlet and exhaust (denitrogen) of two adsorption towers, and control unit is by changing the time of solenoid valve on-off to system The intake and exhaust time of oxygen absorbing unit is accurately controlled.
Flow concentration detecting unit is used to detect the flow and concentration value of obtained oxygen, when detecting obtained oxygen When concentration still relatively low (being lower than 90%), further the parameter of oxygen absorbing unit processed can be carried out according to current system pressure value Adjustment, with oxygen effect most preferably processed.Adjustment mode is further increasing gas supply and evacuation time, further increases service life With the mode of evacuation time are as follows: be not up to system saturation operating pressure (equipment in system working pressure (current system pressure value) The maximum value of permission) when, service life and evacuation time are controlled respectively with small size time stepping increase, and every stepping increases by a step simultaneously Oxygen concentration and system pressure value detection are carried out after 2min, if oxygen concentration not up to requires and pressure is less than system restriction, Continue to increase service life and evacuation time in a stepping manner, if system pressure value have reached equipment permission maximum value or Person's oxygen concentration reaches requirement, then stops the adjusting to service life and evacuation time.And service life stepping amplitude is 0.1s, Evacuation time stepping amplitude is 0.085s.
For example, oxygenerator exports oxygen with the flow of 3L/min, if system working pressure distance reaches system saturation work With 0.1s stepping increase, evacuation time is with 0.085s stepping increase, often there are also when larger surplus, can control service life for pressure 2min is judged according to the oxygen concentration and system pressure parameter value that detect, if oxygen concentration not up to requires and pressure does not surpass System saturation operating pressure is crossed, continues to increase service life in a stepping manner and evacuation time is stopped if pressure has reached maximum Only to the adjusting of service life and evacuation time, if oxygen concentration reaches requirement, also stop the tune to service life and evacuation time Section.
