Water and oil reach 0.01ppm, obtain clean air, and send clean air to oxygenerator 200；
2) oxygen preparation of oxygenerator 200 is divided into upper half cycle and lower half cycle：
21) oxygen preparation in upper half cycle (the first adsorption tower 203) is as follows：
First pneumatic angle pedestal valve 2021 is opened, and the 5th pneumatic angle pedestal valve 2051 is opened, meanwhile, the 4th pneumatic angle pedestal valve 2024 open and
Hand-operated valve 209 is opened：Pure air in air cushioning tank 201 sequentially passes through the first pneumatic angle pedestal valve 2021 and the first adsorption tower
203, pure air is pneumatic by the 5th by obtaining pure oxygen, pure oxygen after the molecular sieve adsorption nitrogen in the first adsorption tower 203
Angle pedestal valve 2051 enters oxygen surge tank 206, forms the oxygen preparation of the first adsorption tower 203；In oxygen preparation, due to hand-operated valve
209 is normally opened, therefore a little pure oxygen enters the second adsorption tower 204 by hand-operated valve 209, by molecular sieve in the second adsorption tower 204
Nitrogen rush out, the nitrogen rushed out enters the second silencer 208 by the 4th pneumatic angle pedestal valve 2024, after noise elimination
(90-100db generally is become into 65db) is drained into air；
22) oxygen preparation in lower half cycle (the second adsorption tower 204) is as follows：
Second pneumatic angle pedestal valve 2022 is opened, and the 6th pneumatic angle pedestal valve 2052 is opened, and the 3rd pneumatic angle pedestal valve 2023 is opened and manually
Valve 209 is opened：Pure air in air cushioning tank 201 sequentially passes through the second pneumatic angle pedestal valve 2022 and the 6th pneumatic angle pedestal valve
2052, pure air is pneumatic by the 6th by obtaining pure oxygen, pure oxygen after the molecular sieve adsorption nitrogen in the second adsorption tower 204
Angle pedestal valve 2052 enters oxygen surge tank 206, forms the oxygen preparation of the second adsorption tower 204；In oxygen preparation, due to hand-operated valve
209 is normally opened, therefore a little pure oxygen enters the first adsorption tower 203 by hand-operated valve 209, by molecular sieve in the first adsorption tower 203
Nitrogen rush out, the nitrogen rushed out enters the first silencer 1207 by the 3rd pneumatic angle pedestal valve 2023, by eliminating the noise it
(90-100db generally is become into 65db) afterwards to be drained into air.
3) be pulsed due to entering the oxygen of oxygen surge tank 206, hence into oxygen it is many, the oxygen gone out is few,
Therefore the pressure transient of oxygen surge tank 206, export pipeline connection pressure-reducing valve 210 and the ball valve 211 of oxygen surge tank 206,
Pressure is adjusted to expected value by pressure-reducing valve 210, so as to obtain a pressure value for stabilization, is adjusted by ball valve 211
The oxygen stream value stablized afterwards, and shown by flowmeter 212.
The present invention is reduced due to realizing oxygen preparation using six pneumatic angle pedestal valves in relatively existing molecular-sieve oxygen generator
The number of pneumatic angle pedestal valve and corresponding cumbersome pipeline, but reach the same oxygen purpose processed of same oxygen purpose processed, while pneumatic
Angle pedestal valve saves the cost of manufacture of molecular-sieve oxygen generator due to expensive, therefore after reducing, extensive therefore, it is possible to obtain
Using.
In above-described embodiment, flowmeter 212 can not limited herein using pointer-type or digital display.
Further, in order to measure the oxygen concentration in oxygen surge tank 206, can be in oxygen surge tank 206 and flow
Any point can set sample point on pipeline between meter 212, and pipeline is set at sample point, and choke valve is set on pipeline
213 and oxygen analyser 214, by the stable oxygen gas flow rate of choke valve 213, the oxygen in oxygen surge tank 206 is shown by oxygen analyser 214
Gas concentration.
Specific embodiment of the invention is these are only, but protection scope of the present invention is not limited thereto, it is any to be familiar with
Those skilled in the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all cover
Within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
