Description
Technical field
It the utility model is related to a kind of oxygen purifying device in oxygen manufacturing technology field, more particularly to a kind of small oxygen
Gas purifier apparatus.
Background technology
Oxygen is widely used in chemical industry, and the technology for manufacturing oxygen in the market is mostly pressure swing adsorption method (PSA)
Technology or turbine expansion refrigeration technology.Pressure swing adsorption method (PSA) technology have flexibly, conveniently, automation mechanized operation, small investment, energy
Low advantage is consumed, but it has the defects of oxygen producing purity is low；It is currently used one kind using turbine expansion refrigeration technology
High-concentration oxygen technology of preparing, but its scale of investment is big, starts time length, and cost is high, is not suitable for miniaturization user.
Utility model content
Needed for defect present in existing oxygenerating technology and reality, the utility model provides a kind of small-sized oxygen purification
Equipment.
To achieve these goals, the measure that the utility model is taken：
A kind of small-sized oxygen purifier apparatus, including air compressor, liquid oxygen collector and oxygen point of use, air compressor
On be sequentially connected the air cushioning tank and gas cooling driers carried out to compressed air except water pretreatment, connection pair on gas cooling driers
Pretreated air is removed water, the adsorbing separation device of carbon dioxide, nitrogen, and adsorbing separation device, which is sequentially connected, collects low concentration oxygen
Oxygen surge tank and liquefied oxygen low temperature refrigerator group, in low temperature refrigerator group connection can remove the liquid oxygen collector of argon gas,
Liquid oxygen collector is connected by the liquid oxygen heat exchanger for the decompression that can gasify with oxygen point of use, is respectively provided between two neighboring element
There is control valve；
The chilling temperature of the low temperature refrigerator group is subzero 183 DEG C；
PU-8 types molecular sieve and 13X type molecular sieves are filled with the adsorbing separation device.
The beneficial effects of the utility model：The purity of product gas of PSA oxygen can be effectively improved, while reduces equipment investment
Cost, device miniaturization, oxygen processed easy to remove, both solved the problems, such as that the purity of PSA technology oxygen producing was low, also overcomed big
The problem of investment height of moldeed depth cool equipment and long startup time.
Brief description of the drawings
Fig. 1 connection block diagrams of the present utility model.
Embodiment
To overcome defect present in existing oxygenerating technology, meet real needs, design a kind of small-sized oxygen purifier apparatus
(such as Fig. 1), including air compressor, liquid oxygen collector and oxygen point of use, it is sequentially connected to compressed air on air compressor
Carry out the air cushioning tank and gas cooling driers except water pretreatment, on gas cooling driers connection pretreated air is removed water,
The adsorbing separation device of carbon dioxide, nitrogen, adsorbing separation device are sequentially connected the oxygen surge tank for collecting low concentration oxygen and liquefaction
The low temperature refrigerator group of oxygen, in low temperature refrigerator group connection can remove the liquid oxygen collector of argon gas, liquid oxygen collector passes through can gas
The liquid oxygen heat exchanger for changing decompression is connected with oxygen point of use, and control valve is provided between two neighboring element；It is described low
The chilling temperature of warm refrigeration unit is subzero 183 DEG C；PU-8 types molecular sieve and 13X type molecules are filled with the adsorbing separation device
Sieve.
Operation principle of the present utility model：Raw air air inlet surge tank is compressed by air compressor and gas is cold dry
Machine is removed water, and pretreated air enters absorber, using air under the centrifugation of adsorbent, is entered by absorber
One step isolates the impurity such as water therein, carbon dioxide, nitrogen, and the oxygen of acquisition enters oxygen surge tank, after buffering
Oxygen accesses low temperature refrigerator group entrance, and the gaseous mixture of PSA oxygen >=93% is cooled to oxygen liquefaction into Cryo Equipment depth
(- 183 DEG C) temperature, operating point temperature is controlled, caused on-condensible gas emptying, height can be discharged in liquid oxygen collector bottom
Purity liquid oxygen, liquid oxygen depressurizes under the gasification of liquid oxygen heat exchanger can be used.
The beneficial effects of the utility model：The purity of product gas of PSA oxygen can be effectively improved, while reduces equipment investment
Cost, device miniaturization, oxygen processed easy to remove, both solved the problems, such as that the purity of PSA technology oxygen producing was low, also overcomed big
The problem of investment height of moldeed depth cool equipment and long startup time.
The utility model can also be generalized to other field applications, such as carbon dioxide separation technical field.It is in the art general
The simple change and replacement of logical technical staff is all within the scope of protection of the utility model.
