Description
[technical field]
The present invention relates to medical molecular sieve center oxygen generating plant, be specifically related to the medical molecular sieve of assisted energy-saving center oxygen generating plant.
[background technology]
At present, medical gas supply equipment is the requisite facility of hospital, and the medical gas that hospital adopts comprises sources of the gas such as medical oxygen, medical compressed air, laughing gas (N2O), mixing air and nitrogen, and is main, also is that what to use always is medical oxygen.At home in the construction of hospital's medical gas supply equipment; In the domestic standard of looking into; The Standard for daylighting design of industrial enterprises (GB50333-2002) that The Ministry of Construction of the People's Republic of China, MOC put into effect in 2002; Clean operation department to hospital has been made regulation, and the handbook that also has has provided more coarse scope with regard to other request for utilizations.But development along with society; Medical gas is in concrete use; For dissimilar diagnosis and treatment wards, dissimilar hospitals; Service condition is inequality in the time of medical oxygen in its medical gas and medical compressed air, and behaviour in service and distribution situation in whole day, full week and the annual seasons are also inequality.For example:
In hospital common diagnosis and treatment ward, patient's the state of an illness is light slightly, and general employing directly provides medical gas, and gas consumption is relatively stable; In special diagnosis and treatment ward; Often patient's the state of an illness is heavier; Need use gas by certain medical facilities; Like Anesthesia machine, respirator, be used for to give emergency treatment to a patient, the patient of acute disease patients such as operation patients, Intensive Care Therapy patient, large-scale sudden situation, patient that traffic hazard causes or naturally evil cause the air feed of the extensive state of an illness, cause the enforcement time long, gas consumption is big.
In dissimilar hospitals, in general hospital and section hospital, because the social responsibility that general hospital bears is bigger, section's class is complete, the gas consumption of hospitals such as orthopaedics hospital, maternity hospital in the relative section hospital, and obviously gas consumption is bigger; And section hospital compares with some specific disease hospitals, compares with the orthopaedics in the specific disease hospital like hospital of lung section, chest hospital, and the gas consumption of hospital of lung section and chest hospital is obviously big, and it is also inequality that this dissimilar hospital's gas consumptions just occurs.
In the air feed whole day of hospital, full week and annual seasons in the air feed process; The situation of the different number of days in one day different periods, a week and the Various Seasonal air feed in 1 year also is not quite similar; As: one day the morning 9:00 to afternoon 3:00 with afternoon 3:00 to evening 12:00 compare the obviously bigger and regular reduction of previous time period gas consumption; The Monday in one week, because operation patients is many, gas consumption was obviously bigger than the weekend to Friday; Throughout the year,, particularly cause gas consumption also bigger at spring and autumn because season alternation causes the RD burst easily.Such situation causes hospital's usefulness gas to be periodic fluctuation, need guarantee that also the air feed process can not be interrupted.
Above situation causes the randomness of hospital's usefulness gas more intense, often along with the change in type, different time and the season of diagnosis and treatment situation, hospital and change; Fluctuation is bigger; The periodicity of hospital's air feed and sudden fluctuation have produced the problem that air feed is unstable, the air feed process loss is bigger, cause security, safety and the validity of air feed to descend; The stability of air feed is concerning the safety of using the gas patient, and loss unnecessary in the air feed process has also increased the air feed cost.Because hospital requires to require the air feed process not to be interrupted than higher to security, stability, safety and the validity of air feed, therefore, it is low to design a kind of safety height and loss, and it is vital having uninterrupted, successional airing system.
