Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely for a kind of high-low oxygen air treatment device. BACKGROUND

[0002] In the gas circuit design of high-low oxygen, air enters pipeline through air compressor, first enters heat exchanger (aluminum block), preliminary reduces air temperature, then enters condenser, removes most of the water vapor in air, after condensation treatment, air still contains part of moisture, removes the remaining moisture and particulate dust in air by three-stage filter membrane, then enters nitrogen-oxygen separation membrane to carry out nitrogen-oxygen separation.

[0003] The prior art finds in practice process, even if after two-stage drainage, if third-stage filtration is in normally closed state, water will still accumulate day after day, leading to that air into membrane is not dry, which affects separation efficiency and service life of separation membrane. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of high-low oxygen air treatment device to solve the problems raised in the above background.

[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of high-low oxygen air treatment device, for being installed on air compressor to filter air, including the first filter and the second filter installed in the side of air compressor, the first filter is connected with the first on-off valve by first pipeline, the second filter is connected with the second on-off valve by second pipeline, the first on-off valve and the second on-off valve are connected with main control board, the other side of the air compressor is also equipped with third filter, the third filter is connected with air compressor by pipeline, and air compressor controls third filter reed by air pressure.

[0006] Preferably, the first filter and the second filter use HMH610 / 03-50 model high-efficiency air filter.

[0007] Preferably, the first on-off valve and the second on-off valve use ZDLP series electric on-off valve.

[0008] Compared with prior art, the utility model has the beneficial effects that: the utility model guarantees that each filter does not store water by the timed drainage of three-stage filtration, air into nitrogen-oxygen separation membrane keeps dry state, can improve the efficiency of nitrogen-oxygen separation, and prolongs the service life of nitrogen-oxygen separation membrane.
