There is an air outlet tee connected between the two groups of air outlet pipes, and the air outlet tee is connected with a combined air pipe, which transports the high-purity nitrogen after adsorption. The connection mode of the pipeline cannot conveniently clean the inside of the adsorption barrel, reducing the use effect of the nitrogen generator.

[0004] Based on this, the utility model designs an air outlet pipeline of an adsorption barrel of a nitrogen generator to solve the above problems. Content of the Utility Model

One end of each of the two groups of air outlet pipes is connected with a middle pipe. There is also an air outlet tee connected between the two middle pipes. One end of the air outlet tee is connected with a combined air pipe. There is also an angle seat valve arranged between the two middle pipes and the air outlet tee. There is also a pressure stabilizing pipe connected between the two middle pipes.

[0007] By adopting the above technical solution, when one adsorption barrel adsorbs nitrogen, the other adsorption barrel can be purged and regenerated, thereby improving the regeneration rate of the adsorbent.

[0008] Preferably, the air outlet pipe and the middle pipe are fixedly installed through a flange plate.

[0009] By adopting the above technical solution, it is convenient for disassembly and assembly.

[0010] Preferably, a ball valve is also arranged on the pressure stabilizing pipe.

[0011] By adopting the above technical solution, the adjustment and control of whether to clean can be achieved.

[0012] Preferably, the connection position of the pressure stabilizing pipe and the middle pipe is close to the air outlet pipe.

[0013] By adopting the above technical solution, the purging effect is enhanced.

[0014] In summary, the present application has the following beneficial technical effects: By providing a voltage stabilizing tube, when one adsorption barrel is operating and the other is not, a small portion of the produced high-purity nitrogen is conveyed through the voltage stabilizing tube to the non-operating adsorption barrel, thereby enabling purging and regeneration of the adsorbent bed inside the adsorption barrel from top to bottom, improving the regeneration rate of the adsorbent.

[0023] Referring to Figure 3 , the nitrogen generator includes a base 1, on which two groups of adsorption barrels 2 and two groups of gas storage barrels 3 are provided. An outlet pipeline 4 is also provided between the two groups of adsorption barrels 2. The bottom ends of the two groups of adsorption barrels 2 are also connected to an intake pipeline, and various mufflers are also provided on the base 1.

[0024] Referring to Figure 1 , an air outlet pipeline of an adsorption barrel of a nitrogen generator, the air outlet pipeline 4 includes air outlet pipes 5 respectively installed on two groups of adsorption barrels 2, one ends of the two groups of air outlet pipes 5 are both communicated with a middle pipe 6, an air outlet tee 7 is also communicated between the two groups of middle pipes 6, one end of the air outlet tee 7 is communicated with a combined air pipe 9, one end of the combined air pipe 9 is communicated with a gas storage barrel 3, an angle seat valve 8 is also arranged between the two groups of middle pipes 6 and the air outlet tee 7, and a pressure stabilizing pipe 10 is also communicated between the two groups of middle pipes 6.

[0027] Furthermore, the air outlet pipe 5 and the middle pipe 6 are fixedly installed through a flange 12.

[0028] The implementation principle of this embodiment is as follows: when both adsorption barrels 2 are working, the ball valve 11 is closed at this time, so that the made high-purity nitrogen enters the combined air pipe 9 through the air outlet pipe 5, the middle pipe 6 and the air outlet tee 7, and then the nitrogen is transported into the interior of the gas storage barrel 3. After closing one side of the adsorption barrel 2 and the angle seat valve 8, the ball valve 11 is opened, and a part of the high-purity nitrogen made by the adsorption barrel 2 on the other side is transported into the interior of the adsorption barrel 2 on one side through the pressure stabilizing pipe 10, which can blow and regenerate the adsorbent bed layer inside the adsorption barrel 2 from top to bottom, improving the regeneration rate of the adsorbent.
