Description
Technical field
The present invention relates to gas separation fields, more particularly to a kind of ambient oxygen partial from device.
Background technique
Traditional method for producing oxygen through is air deep-cooling fractionating process, which can be made the oxygen of high-purity, nitrogen.But in many fields
It closes, as the occasions such as wastewater treatment, metal smelt, chemical emission processing do not need the high purity oxygen as obtained by deep cooling fractionating process
Gas, and oxygen-enriched expense is bigger.For this purpose, people pursue always more economic, simple oxygen enriching method, as molecular sieve becomes
Press absorption method, membrane oxygen enrichment technology.
Film oxygen enriching is to carry out air separation using oxygen permeable membrane, and oxygen-enrichment membrane is advanced, mature.The work of UF membrane air
Principle is the selective penetrated property function of polymer film, and film is made to be in contact with air, under the driving of the pressure at both sides difference of film, due to
Oxygen molecule and nitrogen molecule are different through the rate of film, and for the fast gas of infiltration rate in infiltration lateral enrichment, infiltration rate is slow
Gas is in raw material lateral enrichment, to realize the purpose of separating-purifying air.The key of membrane technology is manufacture high throughput, high selection
Property, long service life again easy cleaned membrane material.But there is dust, impurity in practical applications etc. and causes the film of oxygen permeable membrane
The problem of hole plug, so as to shorten the service life of oxygen permeable membrane.
The nitrogen in air is the molecule for being preferred absorption over a molecular sieve, and it is along two that pressure swing adsorption method, which is produced oxygen-enriched,
What approach carried out: being on the one hand the performance for improving adsorbent, to increase the adsorption capacity of nitrogen and the separation of rich nitrogen；It is another
Aspect is to improve process flow, has various two, three processes according to the exploitation of oxygen-enriched production capacity, purity and performance of the adsorbent,
Adsorbent bed number increase can be improved the oxygen ability that produces, reduce total power consumption, but additional investment and the increased complexity of bed number are economically
Cause prohibitively expensive.So industrial development and application at present it is more be two, three processes.Since the separation of oxygen nitrogen is with pressure
Power is reduced and is improved, therefore pressure-variable adsorption produces adsorptive pressure in oxic process all relatively low, normal pressure absorption-vacuum desorption technique
Power consumption it is lower than pressurized adsorbent-normal pressure desorption technique, the oxygen-enriched method of molecular sieve pressure-variable adsorption is oxygen-enriched similar to oxygen permeable membrane,
Technology is more mature.The gap of void ratio oxygen permeable membrane is big, but similarly there are molecular sieve pores blockage problems.Because molecular sieve pores block
It must replace, cause the very big consumption of the significant wastage and expense of resource.
Magnetic method oxygen enrichment technology is the state-of-the-art technology that oxygen-enriched combusting power-saving technology prepares oxygen-enriched air at present, its advantage is that answering
With range is wide, service life is long, itself consume energy low, oxygen-enriched air low cost.Fundamentally solve at this stage film oxygen enriching method,
The disadvantage of the oxygen-enriched method of molecular sieve pressure-variable adsorption: such as the eyelet blockage problem of oxygen permeable membrane and molecular sieve.The oxygen-enriched principle of magnetic method is benefit
With the different paramagnetic and diamagnetics of oxygen molecule and nitrogen molecular, so that through excessively high magnetic magnetic field not Tongfang occurs for two kinds of gas molecules
To deflection to obtain oxygen-enriched air and nitrogen-rich air, be discharged nitrogen-rich air, remaining is exactly our required oxygen-enriched skies
Gas.The oxygen-enriched primary oxygen-rich concentration of magnetic method can reach 26%--30%, and can oxygen-rich concentration can be reached with plural serial stage
To a higher level.
Patent CN101020569A discloses a kind of magnetic oxygen-rich air machine, mainly by oxygen permeable layer and oxygen-enriched aspiration pump structure
At, the pod with rotating excitation field is provided on aspiration pump, using rotating excitation field generate magnetic force will accumulate on oxygen-gathering device
Oxygen be efficiently directed into aspiration pump, but there are oxygen-rich concentrations it is not high, oxygen-enriched narrow-minded the problems such as.
Patent CN101857200A discloses a kind of novel combined magnetic force oxygen enriching device, and oxygen-enriching device uses thtee-stage shiplock
It is oxygen-enriched, oxygen purity is improved step by step, but that there are oxygen concentrations is higher in actual moving process, what oxygen was more difficult to be detached from from magnetic field
Problem.
