Abstract
The utility model provides oxygen generating equipment which comprises a separation container, an air inlet, a zeolitic molecular screen, a nitrogen outlet, a vacuumizer and an oxygen outlet; wherein the air inlet, the nitrogen outlet and the oxygen outlet are formed in the separation container; the inner part of the separation container is divided into an oxygen cabin and a nitrogen cabin through the zeolitic molecular screen; the front part of the oxygen cabin is connected with the air inlet; the rear part of the oxygen cabin is connected with the oxygen outlet; each cabin is divided into 3 to 10 microcavities; the microcavities are communicated through small holes. The oxygen generating equipment can be used to reduce the concentration of the nitrogen step by step, so that more than 97% of highly-purified oxygen can be provided, and the oxygen generating equipment is suitable for middle large-sized hospitals or equipment needling oxygen.
Description
Technical field
The utility model relates to a kind of oxygen generating plant, especially PSA oxygen generator equipment.
Background technology
Present pressure-variable adsorption vacuum desorption (being called for short VPSA) oxygen generating plant, namely penetrate under the atmospheric condition, utilize the impurity such as the airborne nitrogen of the dedicated molecular sieve used selective adsorption of VPSA, carbonic acid gas and water, under the condition that vacuumizes, molecular sieve is carried out desorb, thereby circulation makes the higher oxygen of purity (90 ~ 94%).The VPSA energy consumption is lower, and larger its energy consumption of equipment is lower.
The VPSA oxygen generation system mainly is comprised of gas blower, vacuum pump, switching valve, adsorber and oxygen equilibrium tank.Raw air is pressurized to 0.3-0.5barg by Root's blower and enters wherein in the adsorber after the suction port strainer is removed dust granule.Filled with adsorbent in the adsorber, wherein moisture, carbonic acid gas, and a small amount of other gaseous fraction be loaded in the activated alumina of bottom in the adsorber ingress and adsorb, nitrogen is loaded in the zeolite molecular sieve on activated alumina top and adsorbs subsequently.And oxygen (comprising argon gas) drains into oxygen equilibrium tank from the adsorber top exit as gas product for non-absorbed component.
When this adsorber is adsorbed onto to a certain degree, the state that will reach capacity of sorbent material wherein, utilize vacuum pump that it vacuumized (with absorption opposite direction) by switching valve this moment, and vacuum tightness is 0.65-0.75barg.The moisture that has adsorbed, carbonic acid gas, nitrogen and a small amount of other gaseous fraction are drawn out of and drain into atmosphere, and sorbent material obtains regeneration.
But present structure is still too complicated, and purifying gas output is not very high.
Summary of the invention
The utility model provides a kind of gas yield high oxygen generating plant.
The utility model is achieved through the following technical solutions:
A kind of oxygen generating plant is characterized in that by separation vessel air inlet, the zeolite molecules screen cloth, nitrogen outlet, evacuator, oxygen outlet forms, and air inlet is arranged, nitrogen outlet on the separation vessel, oxygen outlet, separation vessel inside becomes oxygen cabin and nitrogen cabin by the zeolite molecular sieve grid, and the oxygen cabin front connects air inlet, and the back connects oxygen outlet, the cabin is divided into 3-10 microcavity, keeps aperture to be communicated with between the microcavity.
Progressive effect of the present utility model is: can utilize the concentration that reduces step by step nitrogen, thereby highly purified oxygen is provided.
Description of drawings
Accompanying drawing is synoptic diagram of the present utility model.
Wherein: 1, oxygen outlet; 2, the zeolite molecules screen cloth; 3, air inlet; 4, nitrogen outlet; 5, evacuator.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further: oxygen generating plant is by separation vessel, air inlet 3, zeolite molecules screen cloth 2, nitrogen outlet 4, evacuator 5, oxygen outlet 1 forms, and air inlet 3 is arranged, nitrogen outlet 4 on the separation vessel, oxygen outlet 1, connect evacuator 5 on the nitrogen outlet, separation vessel inside becomes oxygen cabin and nitrogen cabin by zeolite molecules screen cloth 2 lattice, and the oxygen cabin front connects air inlet 3, the back connects oxygen outlet 1, the cabin is divided into 3-10 microcavity, keeps aperture UNICOM between the microcavity, connects evacuator 5 on the nitrogen outlet.
Prioritization scheme one, the oxygen outlet cross section is greater than 1/5 of air inlet.
Prioritization scheme two, zeolite molecules screen cloth are made into reciprocation type membrane separation net, improve the gas processing amount.
Adopt oxygen generating plant of the present utility model, can improve oxygen concentration and reach more than 97%, be fit to medium-and-large-sized hospital or oxygen demand equipment.
