Description
The utility model relates to the oxygen enrichment production equipment in air separation field, produces machine for a kind of oxygen enrichment, is particularly useful for medical treatment and healthcare field.
At present, transformation adsorbing separation air is got the main method that oxygen is system oxygen.Because the operational characteristic of this method determines, transformation is adsorbed and need just can be achieved by a plurality of electronic or operated pneumatic valves, and the purification of air raw material is also had higher requirement.In recent years, all develop the miniature or small-sized oxygen generating plant of multiple employing pressure swing absorption process both at home and abroad, be used for medical treatment and health care purpose.And these oxygen generating plants mostly adopt industrial pressure swing adsorption technique technology, and this techniqueflow is long, equipment is many, thereby cause this oxygen generating plant price height, volume is big and Heavy Weight.
The utility model is that the oxygen enrichment that provides a kind of process simplification at the existing defective of above-mentioned variable-pressure adsorption separating method, equipment is simple, with low cost and is adapted to level of mass consumption is produced machine.
Oxygen enrichment of the present utility model is produced machine, be that two adsorption towers of and mutually hocket adsorbing separation and desorb reproduction operation identical by a pair of structure, the three-way connection that is connected in the two-position five-way valve of this two adsorption towers, one end and is connected in this two adsorption towers other end are constituted, this adsorption tower includes the tower body of a sealing, has a cavity volume in this tower body, in the tower body cavity volume, be equipped with the molecular sieve of nitrogen in the energy absorbed air, on the relative two sides of tower body wall, have inlet union and outlet connection respectively.
The utility model and existing transformation adsorbing separation are got the oxygen method and compared and have following tangible advantage: 1, equipment is simple.The corollary equipment that only needs to adopt a pair of adsorption tower in this oxygen enrichment production process and adapt can reach the purpose that oxygen enrichment is produced; 2, flow process is short.Air is compressed, cooling enters in the adsorption tower and can produce oxygen-enriched air, and nitrogenous high nitrogen-rich air can successfully be separated by the alternation of two adsorption towers simultaneously; 3, the oxygen-enriched air of producing contain oxygen rate height, generally can reach 35%～95%.
Below in conjunction with accompanying drawing structure of the present utility model and technology contents thereof are further described:
Fig. 1 is a structural representation of the present utility model;
The schematic flow sheet that Fig. 2 produces for the utility model oxygen enrichment.
Referring to Fig. 1, oxygen enrichment of the present utility model is produced machine, is that two adsorption towers 1 and 1 ｀ of and mutually hocket adsorbing separation and desorb reproduction operation identical by a pair of structure, the three-way connection 3 that is connected in the two-position five-way valve 2 of this two adsorption tower 1 and 1 ｀, one end and is connected in this two adsorption tower 1 and the 1 ｀ other end constitute; This adsorption tower 1 or 1 ｀ include the tower body 11 of a sealing, have a cavity volume 12 in this tower body 11, are equipped with the molecular sieve 13 of nitrogen in the energy absorbed air in the tower body cavity volume, have inlet union 14 and outlet connection 15 on the relative two sides of tower body respectively.
Above-mentioned said sealing tower body 11 is that the end cap 112 by light-wall pipe 111 and two ends constitutes, central authorities at this end cap 112 have an installing hole 113, and the end cap 112 at two ends is fixed in light-wall pipe 111 two ends by screw rod 114 and two nuts 115 of tightening the installing hole place.Between nut 115 and end cap 112 and end cap 112 and light-wall pipe 111,, do not leak to guarantee the pressure-air in the tower body by seal with elastometic washer.
Above-mentioned said molecular sieve 13 is by being installed in air permeable plate 16 fixed installations on the screw rod, so that cleaning and maintenance.
Above-mentioned said inlet union 14 and outlet connection 15 are positioned on respectively on the above-mentioned two end cap 112.Above-mentioned a pair of adsorption tower 1 and 1 ｀ inlet union 14 separately with can control the hocket two-position five-way valve 2 of adsorbing separation and desorb reproduction operation of two adsorption towers 1 and 1 ｀ and link to each other, other three interfaces of this two-position five-way valve 2 can be respectively after filtration disappear, the outlet of compressor compresses and the cooled air intlet of cooler and this two adsorption tower air after carrying out desorption and regeneration respectively; This two-position five-way valve 2 can be selected existing electronic two-position five-way valve (relevant circuit control principle no longer illustrates at this, sees also the relevant description of product) for use, and its power supply can be alternating current, and also can adopt voltage is the direct current of 12V or 24V.Above-mentioned a pair of adsorption tower 1 links to each other with the three-way connection 3 that is connected with gas storage equipment with 1 ｀ outlet connection 15 separately; This three-way connection 3 mainly is the oxygen rich gas that wherein an adsorption tower 1 or 1 ｀ are produced to be carried out output quantity distribute with the purging consumption that enters in another adsorption tower 1 ｀ or 1, all presses to finish pressure swing adsorption technique, the function of blowback.
Below in conjunction with Fig. 2 oxygen preparation of the present utility model is further described.Referring to Fig. 2, air enters compressor 5 compressions behind air filtration silencer 4, enter one of them adsorption tower 1 or 1 ｀ by two-position five-way valve 2 controls again after cooler 6 coolings; Compression cooling air airborne nitrogen of molecular sieve adsorption in this tower in adsorption tower 1 or 1 ｀ carries out nitrogen oxygen to be separated.Oxygen-enriched air after the separation is divided into two parts through three-way connection 3 again, and a part enters gas storage equipment 7 and stores the use for the user, and in use, oxygen rich gas is defeated by the user through pressure-regulating valve 8, flowmeter 9 and wetting bottle 10; Another part enters in this adsorption tower from the outlet connection 15 of another adsorption tower 1 ｀ or 1, purge molecular sieve and make adsorbent reactivation, and the rich nitrogen waste gas in this adsorption tower 1 ｀ or 1 is discharged through two-position five-way valve 2 and exhaust silencer again; Two adsorption towers are controlled alternation by two-position five-way valve, can produce oxygen content continuously and be 30%～95% oxygen-enriched air.
