Abstract
The utility model discloses a batch oxygen generating device for pressure swing adsorption. The utility model is characterized in that a single tower process flow that only an adsorption tower is used for producing oxygen is adopted. When air enters the adsorption tower, the oxygen of needed purity can be provided by the batch oxygen generating device; when the air is exhausted by the adsorption tower, a filled molecular sieve is desorbed, and the oxygen is not provided. The utility model has the advantages of simple flow, light weight, small size and low cost. The batch oxygen generating device is suitable for occasions using the oxygen in batch mode such as indoor air exchange, oxygen charging of a fish pond, etc.
Description
The utility model is a kind of oxygenerator, particularly a kind of intermittent type pressure swing adsorption oxygen making device.
This oxygenerator is to use the absorption principle separation of air and produce oxygen.Because zeolite molecular sieve is to the difference of oxygen, the component balanced loading capacity of nitrogen, under 0.3-0.4MPa pressure, when process air streams was crossed the molecular sieve bed layer, the nitrogen component preferentially was adsorbed, and effluent air is an oxygen.When absorption reaches capacity, utilize the method desorb of decompression, recover the use ability of molecular sieve, transformation that Here it is absorption.
Existing pressure swing adsorption oxygen making device is that two, three, four or more adsorption tower compose in parallel continuous oxygen supply device, also can be described as the multitower flow process.And, the drying tower of still needing before the adsorption tower.This flow process, adsorption tower is many, pipeline is complicated, switching valve is many, automatically the reference mark is many, so cost is very high and operational failure easily takes place.
The utility model provides a kind of list tower pressure swing adsorption oxygen making device, and it still can provide the oxygen of required purity, compares with the multitower flow process, and its installation weight alleviates half, and cost also reduces by half.
The utility model oxygenerator is to realize oxygen preparation like this: only use an adsorption tower in the flow process, in adorn two kinds of molecular sieves.When air passed through the adsorption tower bed from bottom to top, airborne moisture content and nitrogen molecule were adsorbed, and the oxygen molecule that is not adsorbed flows out from adsorption tower becomes product oxygen.After absorption was carried out one to two minute, the air of going into adsorption tower cut off, and the oxygen reverse checkvalve of adsorption tower is also closed, and connected with vacuum pump to vacuumize.
The flow process of the utility model oxygenerator is provided by accompanying drawing 1.
This device comprises: air compressor machine (1), vacuum pump (6), dry bed (7), oxygen nitrogen separate bed (8), control magnetic valve (2), (3), (4), (5), oxygen reverse checkvalve (9).
Concrete product oxygen process is: air compressor machine is sucked air by atmosphere, enters adsorption tower through magnetic valve (3), removes airborne water content in dry bed, then obtains oxygen in separating bed, and oxygen is sent through reverse checkvalve (9).Through 60 seconds the emptying switching valve (2) open, switching valve (3) cuts out, the gas emptying of air compressor machine.Switching valve (4) is opened then, and blow-off valve (5) is opened, and emptying was closed after 10 seconds, is vacuumized 20 seconds by vacuum pump.Handoff procedure is all realized automatically by the changeover program controller.
The adsorption tower structure of intermittent type omnibus control system is provided by accompanying drawing 2, and adsorption tower is by last cover 1), inner core screen cloth 2), inner barrel 3), outer cylinder body 4), downstream end 5), the outlet screen cloth 6), cylindrical shell lower screen cloth 7), the tube end 8), inlet connection 9) form.
Claims (3)
1, intermittent type pressure swing adsorption oxygen making device, this device has only the bitubular adsorption tower of adorning two kinds of molecular sieves in one, the bottom of adsorption tower links to each other with air compressor machine (1) through intake valve (3), link to each other with vacuum pump (6) through vent valve (4), it is characterized in that making oxygen and desorb hockets in single tower body, automatically switch by single card microcomputer control, and switching valve all adopts magnetic valve once to control.
2, device according to claim 1, the structure that it is characterized in that adsorption tower is a bitubular dual bed, inner core is a drying layer, remove airborne moisture content, urceolus is oxygen, nitrogen separating layer, produces oxygen, tower body is very little, and (H: D), the aspect ratio of this device is greater than 8 but have bigger aspect ratio.
3, device according to claim 1 is characterized in that the switching valve on the device pipeline adopts four magnetic valves (2), (3), (4), (5), and single card microcomputer is once controlled direct driving electromagnetic valve switch, realizes intermittent oxygen supply.
