The filling method is characterized in that a sodium molecular sieve material and a lithium molecular sieve material are segmentally filled, the molecular sieve adjoining the air inlet end of the molecular sieve bed is a sodium molecular sieve, the molecular sieve adjoining the air outlet end of the molecular sieve bed is the lithium molecular sieve, and the mass of the sodium molecular sieve accounts for 10%-20% of that of the molecular sieve materials. According to the filling method, the advantages of the sodium molecular sieve and the lithium molecular sieve can be integrated, the oxygen concentrator can meet the air-entrainment conditions of wet polluted environments of airplanes, vehicle-mounted devices, tanks and the like, and breathing air which meets the oxygen demand of a human body can be produced.
Description
Technical field
The invention belongs to molecular sieve oxygen generation technology, relate to the improvement to a kind of filling method of oxygen concentrator molecular sieve bed.
Technical background
When the molecular sieve bed that existing molecular sieve oxygen generation technology adopts loads, molecular screen material used is single sodium molecule sieve or lithium dimer sieve, and wherein, the adsorption efficiency of sodium molecule sieve is lower, but its water tolerance is stronger, the steam adsorbing during desorb is easy to be rinsed the band of gas and walks; And the adsorption efficiency of lithium dimer sieve is high, but water-absorbent is also stronger simultaneously, in the situation that the compressed gas water capacity of introducing is high, easily loses adsorption.At present, the sifting bed oxygen generation efficiency that all loads sodium molecule sieve is on the low side, needs to strengthen molecular sieve loadings and could meet oxygen making amount demand; And the molecular sieve bed oxygen generation efficiency that all loads lithium dimer sieve material is high, but owing to easily being lost absorption property by vapour corrosion.
Summary of the invention
The object of the invention is: a kind of filling method with the oxygen concentrator molecular sieve bed in higher adsorption efficiency and work-ing life is provided, so that the advantage of comprehensive sodium molecule sieve and lithium dimer sieve, make oxygen concentrator can adapt to for a long time the bleed condition of the moist contaminate environment such as aircraft, vehicle-mounted and tank, produce and meet the respiratory gas of oxygen demand for human body.
Technical scheme of the present invention is: a kind of filling method of oxygen concentrator molecular sieve bed, and molecular sieve bed is a cylinder, and the inlet end of molecular sieve bed is with inlet mouth, and the outlet side of molecular sieve bed is with air outlet; It is characterized in that, it is loaded by sodium molecule sieve and two kinds of molecular screen material segmentations of lithium dimer sieve, molecular screen material in abutting connection with molecular sieve bed inlet end is sodium molecule sieve, molecular screen material in abutting connection with molecular sieve bed outlet side is lithium dimer sieve, and the quality of sodium molecule sieve accounts for 10%～20% of molecular screen material quality.
Advantage of the present invention is: a kind of filling method with the oxygen concentrator molecular sieve bed in higher adsorption efficiency and work-ing life is provided, the advantage that comprehensively sodium molecule sieve and lithium dimer sieve, make oxygen concentrator can adapt to for a long time the bleed condition of the moist contaminate environment such as aircraft, vehicle-mounted and tank, produce and meet the respiratory gas of oxygen demand for human body.
Embodiment
Below the present invention is described in further details.A filling method for oxygen concentrator molecular sieve bed, molecular sieve bed is a cylinder, and the inlet end of molecular sieve bed is with inlet mouth, and the outlet side of molecular sieve bed is with air outlet; It is characterized in that, it is loaded by sodium molecule sieve and two kinds of molecular screen material segmentations of lithium dimer sieve, molecular screen material in abutting connection with molecular sieve bed inlet end is sodium molecule sieve, molecular screen material in abutting connection with molecular sieve bed outlet side is lithium dimer sieve, and the quality of sodium molecule sieve accounts for 10%～20% of molecular screen material quality.
Principle of work of the present invention is: sodium molecule sieve is filled in to inlet end, and lithium dimer sieve fills in outlet side, utilizes sodium molecule sieve water tolerance strong, and the steam adsorbing during desorb is easy to be rinsed the band of gas and walks, and has improved oxygenerator work-ing life; Utilize lithium dimer sieve adsorption efficiency high, improved gas product oxygen-rich concentration, reduced loadings, thereby made oxygen concentrator there is higher adsorption efficiency and work-ing life.
