Abstract
The utility model discloses a small-sized machine for preparation of oxygen with a molecular sieve, used for providing rich oxygen for laboratories, medical sanitation, improvement of the gas structure, air cleaning of families and ambulances. Advanced, scientific and reliable molecular sieve mini oxygen-making devices with low working conditions are arranged in remote oxygen source regions and areas without enough oxygen supply for changing the traditional oxygen supply by steel bottles. The utility model is characterized in that the small-sized machine for preparation of oxygen with the molecular sieve comprises a circuit control switch, an AC-DC inversion power system, a microcomputer automatic control working programming system, a system for providing raw material gas, making oxygen through the transformation desorption and eliminating the waste gas, and a product oxygen aseptic filtration system.
Description
The small-sized oxygenerator of a kind of molecular sieve.
China's oxygen generating plant mostly is the cold oxygen generation method in source at present, adopt traditional steel cylinder high pressure storage oxygen, though existing molecular sieving oxygenerator few in number occurs, but still exist volume big and weigh, noise is big, cost is high, can not AC/DC universal, still make troubles to the user.
The utility model oxygenerator has overcome above-mentioned shortcoming, and except solving oxygen supply equipment, oxygen source deficiency, it provides more suitable AC/DC oxygen generating plant for battlefield, civilian ambulance, uses oxygen more economical, convenient.
The utility model oxygenerator, it is by circuit controling switch, alternating current-direct current inverter system, microcomputer automatic control working routine system.Supply raw materials gas, transformation desorption system oxygen, the system that scavenges, product oxygen sterile filtration system forms.Circuit controling switch is to connect switch (19), system's cut-off switch (20) by as shown in Figure 2 system, and the alternating current-direct current inverter system is the alternating current-direct current contravariant transformer as shown in Figure 5, and potentiostat shown in Figure 3.Microcomputer automatic control working routine system is a single board computer 8035(24 by as shown in Figure 6), electromagnetic slide valve (28), (29) of addressed memory (25), extender (26), analog line driver (27), program store (31), control working routine.The gas of supplying raw materials, transformation desorption system oxygen, the system of scavenging is the air filter (1) by as shown in Figure 1, positive pressure side air compressor (3) in the positive and negative combination unit, scatterer (2), air reservoir (5) will compress cleaned air passes by electromagnetism 3 position-5 way guiding valve (17), input adsorber (15) is through interior dress 5A molecular sieving system oxygen (adsorber (15) once is an one-period with (6) alternation), positive negative pressure unit mahine group negative pressure end (4) the air compressor negative pressure of warp vacuumizes and makes the waste gas desorption, enters atmosphere by sound damper (18).Product oxygen is entered oxygen holder (13), reducing valve (11), strainer (10), oxygen flow meter (9), enters sterile filtration system core filter stick (7), wetting bottle (8) supply patient directly uses or pack storage oxygen poly-bag into through check valve (14) or (12) by adsorber (15) or (6).
The small-sized oxygenerator of the utility model molecular sieve, except that said structure, also has power failure alarm device as shown in Figure 4, reference mark a, b, c, d, e, the f of other various states guard signal inputs Fig. 6 single board computer 8035 are as high/low pressure, vacuum pressure, dirt dust excess etc.
The utility model structure shown in the figure I is a cord wood.
The small-sized oxygenerator of the utility model molecular sieve, use the airborne oxygen of molecular sieve transformation fractionation by adsorption at normal temperatures, nitrogen is produced medical oxygen, be to utilize synthesis zeolite in adsorption process, nitrogen and oxygen to be had selectivity, promptly in higher pressure range to the adsorptive capacity of nitrogen greater than adsorptive capacity to oxygen and argon, in decompression or when vacuumizing, the nitrogen that has adsorbed and on a small quantity by the oxygen of its absorption and argon by the development of the principle of desorb.
