Enter into the adsorption tower desorbed.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Describe the technical solution of the utility model in detail below in conjunction with the accompanying drawings：
Such as Fig. 1, a kind of medical oxygen producing purifying plant, including left adsorption tower and right adsorption tower, the adsorption tower is provided with sky
Gas entrance, solution suction and exhaust ports and oxygen delivery outlet, the air intake of left adsorption tower are connected with left air door 1, solution suction and exhaust ports
Left bank air valve 2 is connected with, the air intake of right adsorption tower is connected with right air door 3, solution suction and exhaust ports and is connected with right exhaust
Valve 4, the present apparatus also includes outlet pipe, and the oxygen delivery outlet of left adsorption tower passes through the air inlet of left check valve 6 and outlet pipe
End is connected, and the oxygen delivery outlet of right adsorption tower is connected by right check valve 7 with the inlet end of outlet pipe, each check valve
Conducting direction is by adsorption tower to outlet pipe.
The medical oxygen producing purifying plant also includes return line, and the outlet side of the outlet pipe passes through return air valve 9
It is connected with return line and is connected with the output valve 8 for connecting oxygen storage tank, the return line passes through the left valve of return-air
Door 10 is connected with left adsorption tower and is connected by the right valve 11 of return-air with right adsorption tower；
The medical oxygen producing purifying plant also includes the oxygen analyser 12 being arranged on outlet pipe；
The medical oxygen producing purifying plant also includes PLC, the PLC and above-mentioned each valve and oxygen determination
Instrument 12 is respectively connected with.
Also it is connected between left adsorption tower and right adsorption tower by equal air pipe, the equal air pipe is provided with to be controlled with PLC
The equal air valve 5 that device processed is connected.
Scavenging conduit 13, the internal diameter phase of the internal diameter of scavenging conduit 13 and other pipelines are also associated between left adsorption tower and right adsorption tower
