Description
Technical field
The present invention relates to a kind of oxygenerator, belong to medical instruments field.
Background technology
The oxygenerator that we often say, it is oxygen collector that English is expressed as " Oxygen concentrator " meaning.By principle common two kinds of oxygen collectors on the market: one is to produce oxygen with molecular sieve, one is to use " attached oxygen film " to claim again " oxygen permeable membrane " product oxygen.First " molecular sieve " PSA oxygenerator, is that German De Lin company manufactures the earliest, apart from 100 years soon the present.The seventies in last century, the oxygen mfg. machine with miniature molecular sieve of the U.S. started to enter home oxygen therapy field.The principle of work of home-use oxygenerator and most of medical oxygenerator is, based on attractant (zeolite molecular sieve), the difference of oxygen, nitrogen adsorptive power in air is realized to the separation of oxygen, nitrogen.When air enters the bed that sorbent material is housed, nitrogen adsorption ability is adsorbed more by force, and oxygen is not adsorbed, and can obtain at adsorption bed exit end like this oxygen of high density.Because sorbent material has the pressure-dependent characteristic of its adsorptive capacity, change its pressure, can make to adsorb the adsorption and desorption operation that hockets.But it is bad that current oxygenerator exists air filtration effect, thereby directly affect the life-span of compressor and molecular sieve, because airborne granule foreign enters cylinder, can lose cup leather, affect the resistance to air loss of cylinder, thereby reduce oxygen generation efficiency.In air, contain moisture content, if do not add measure, allow it enter molecular sieve tower cylinder and can have a strong impact on the work-ing life of molecular sieve.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of safe and reliable, strengthen air filtration effect, improve the oxygenerator in compressor and adsorbing tower with molecular sieve work-ing life.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of oxygenerator, is characterized in that: the air outlet termination that the air outlet that the air outlet end that the air outlet end that is provided with absorbed type drying device, absorbed type drying device in the air outlet of air filter is established admission air silencer, admission air silencer is established air outlet termination molecular brush adsorption tower, the molecular brush adsorption tower of oil-free air compressor, oil-free air compressor is furnished with oxygen container, oxygen container purifies oxygen system, purifies air outlet termination oxygen flow meter and the oxygen exhaust of oxygen system.
Further, above-mentioned oxygenerator, arranges back pressure valve between the air outlet of wherein said oxygen container and described purification oxygen system, and the air outlet of described adsorbing tower with molecular sieve is connected with the inlet mouth of described oxygen container by check valve.
Further, above-mentioned oxygenerator is wherein provided with two containers in described sorption drying device, and the thick water absorbent that removes is housed in one of them container, the degree of depth is housed except water absorbent in another container.
The principle of work of oxygenerator of the present invention is: air enters after air filter, filters out the impurity such as airborne moisture and dust, then through absorbed type drying device, further dewaters, and air out enters admission air silencer from absorbed type drying device and carries out noise reduction.Gas after noise reduction compresses through oil-free air compressor, air after compression enters molecular brush adsorption tower by nitrogen adsorption, thereby maintenance high-concentration oxygen, oxygen is collected into oxygen container afterwards, between the air outlet of oxygen container and described purification oxygen system, back pressure valve is set, when gas is carried out to voltage stabilizing, has increased the effect of removing carbonic acid gas.Purifying afterwards oxygen system further regulates the purity of oxygen.When purifying the air outlet termination oxygen flow timing of oxygen system, its high-purity oxygen output flow is under control, and final, high-purity oxygen is exported to patient through oxygen exhaust.
Oxygenerator provided by the invention, reasonable in design, safe and reliable, strengthened air filtration effect, improved the work-ing life of compressor and adsorbing tower with molecular sieve, be applicable to generally applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of oxygenerator, is characterized in that: the air outlet termination that the air outlet that the air outlet end that the air outlet end that is provided with absorbed type drying device, absorbed type drying device in the air outlet of air filter is established admission air silencer, admission air silencer is established air outlet termination molecular brush adsorption tower, the molecular brush adsorption tower of oil-free air compressor, oil-free air compressor is furnished with oxygen container, oxygen container purifies oxygen system, purifies air outlet termination oxygen flow meter and the oxygen exhaust of oxygen system.
Further, above-mentioned oxygenerator, arranges back pressure valve between the air outlet of wherein said oxygen container and described purification oxygen system, and the air outlet of described adsorbing tower with molecular sieve is connected with the inlet mouth of described oxygen container by check valve.
Further, above-mentioned oxygenerator is wherein provided with two containers in described sorption drying device, and the thick water absorbent that removes is housed in one of them container, the degree of depth is housed except water absorbent in another container.
While using above-mentioned oxygenerator, air enters after air filter, filters out the impurity such as airborne moisture and dust, then through absorbed type drying device, further dewaters, and air out enters admission air silencer from absorbed type drying device and carries out noise reduction.Gas after noise reduction compresses through oil-free air compressor, air after compression enters molecular brush adsorption tower by nitrogen adsorption, thereby maintenance high-concentration oxygen, oxygen is collected into oxygen container afterwards, between the air outlet of oxygen container and described purification oxygen system, back pressure valve is set, when gas is carried out to voltage stabilizing, has increased the effect of removing carbonic acid gas.Purifying afterwards oxygen system further regulates the purity of oxygen.When purifying the air outlet termination oxygen flow timing of oxygen system, its high-purity oxygen output flow is under control, and final, high-purity oxygen is exported to patient through oxygen exhaust.
Be provided with and thick can realize the degree of depth removal of impurity gas that dewaters except the absorbed type drying device of water absorbent except water absorbent and the degree of depth.
Between the air outlet of oxygen container and described purification oxygen system, back pressure valve being set, is when gas is carried out to voltage stabilizing, to have increased the effect of removing carbonic acid gas.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
