[0023] Implementation

[0024] Please see Figure 1 -4, A multi-tower skid-mounted pressure swing adsorption device, comprising: a base plate 1 and a fixed platform 2;

[0025] An adsorption tower 3 is fixedly installed on the top of the base plate 1. An upper pipeline 4 is fixedly installed on the top of the adsorption tower 3. A lower pipeline 5 is fixedly installed on the bottom of the adsorption tower 3. A first solenoid valve group 6 is fixedly installed inside the upper pipeline 4 and the lower pipeline 5. A second solenoid valve group 7 is fixedly installed inside the upper pipeline 4 and the lower pipeline 5.

[0026] The top of the upper pipeline 4 is fixedly installed with a finished pipeline 8, and the inside of the finished pipeline 8 is fixedly installed with a flow monitor 9. The inside of the fixed platform 2 is fixedly installed with a gas storage tank 10. The top of the bottom plate 1 is fixedly installed with a support rod 11, and the top of the support rod 11 is fixedly installed with an operating platform 12. The inside of the adsorption tower 3 is fixedly installed with an adsorbent 20.

[0027] The technical solution provided in this embodiment is as follows: In use, the required value is first set through the PLC inside the control panel 12, and the second solenoid valve group 7 is closed through the PLC. Then, the PLC starts the compressor 13 through the wire and pumps the raw material gas through the raw material gas pipe 14 into the lower pipeline 5 through the first connecting pipe 15. Then, it enters the interior of the three adsorption towers 3 in the latter half, and then the hydrogen is purified by the adsorbent 20. The impurities are left in the adsorption tower 3. The purified hydrogen enters the upper pipeline 4 and then through the finished product pipeline 8 so that the purified hydrogen enters the gas storage tank 10. Inside the system, the flow monitor 9 monitors the flow rate of hydrogen entering the finished product pipeline 8 in real time. When the adsorbent 20 inside the three adsorption towers 3 in the latter half cannot adsorb impurities and purify oxygen, the first solenoid valve group 6 is closed and the second solenoid valve group 7 is opened to allow the gas to be purified to enter the three adsorption towers 3 in the first half for hydrogen purification. Then, the vacuum pump 16 is turned on to remove the waste gas inside the three adsorption towers 3 in the latter half through the second connecting pipe 19 and the lower pipeline 5, so that the adsorbent 20 is reduced. Then, the waste gas is discharged through the waste gas pipe 18.

[0033] Specifically, by fixing solenoid valve 61 and solenoid valve 62 inside the upper pipeline 4, and fixing solenoid valve 63 and solenoid valve 64 inside the lower pipeline 5, the opening and closing of the first solenoid valve group 6 can be controlled by the PLC, thereby controlling the flow direction of gas inside the upper pipeline 4 and the lower pipeline 5.

[0034] Furthermore, the second solenoid valve group 7 includes solenoid valve 71 (number 5), solenoid valve 72 (number 6), solenoid valve 73 (number 7), and solenoid valve 74 (number 8), wherein solenoid valve 71 (number 5) and solenoid valve 72 (number 6) are fixedly installed inside the upper pipeline 4, and solenoid valve 73 (number 7) and solenoid valve 74 (number 8) are fixedly installed inside the lower pipeline 5.

[0035] Specifically, by classifying solenoid valves 71 (number 5), 72 (number 6), 73 (number 7), and 74 (number 8) into the second solenoid valve group 7, the flow direction of gas inside the PLC control device can be more precise.

[0036] Furthermore, the PLC is connected to the first solenoid valve group 6, the second solenoid valve group 7, the flow monitor 9, the compressor 13, and the vacuum pump 16 via wires.

[0037] Specifically, by connecting the first solenoid valve group 6, the second solenoid valve group 7, the flow monitor 9, the compressor 13, and the vacuum pump 16 to the PLC via wires, the PLC can control the first solenoid valve group 6, the second solenoid valve group 7, the flow monitor 9, the compressor 13, and the vacuum pump 16.
