Abstract

The invention discloses an intelligent automatic hydrogen-nitrogen proportioning device which comprises a hydrogen pressure stabilizing tank, a nitrogen pressure stabilizing tank and a blending tank,wherein a gas mixing pipeline is arranged on the blending tank, the nitrogen pressure stabilizing tank is communicated with the gas mixing pipeline through a nitrogen conveying pipeline, the hydrogenpressure stabilizing tank is communicated with the gas mixing pipeline through a hydrogen conveying pipeline, a mixed gas detection pipeline is connected into the gas mixing pipeline, and the mixed gas detection pipeline comprises a hydrogen analyzer connected through a conveying pipe; the hydrogen analyzer is connected with a PID controller; the PID controller is connected with a regulating valveon the hydrogen conveying pipeline; wherein a gas outlet pipeline is arranged on the mixing tank, and an emptying valve and a mixed gas discharge valve, which are arranged in parallel, are arranged at the outer end part of the gas outlet pipeline. According to the invention, the gas demand of a special working condition that the pressure and the flow of a mixed gas use point are continuously changed is effectively improved; the frequency of hydrogen concentration change is reduced, the time and the frequency of manually correcting the hydrogenation amount are saved, and the utilization rate of the mixed gas is effectively improved.

Description

technical field [0001] The hydrogen-nitrogen mixed gas distribution equipment involved in the present invention is specifically an intelligent automatic hydrogen-nitrogen proportioning device. Background technique [0002] Hydrogen-nitrogen mixed gas distribution equipment is a device used to mix and distribute hydrogen and nitrogen in proportion. Although the existing hydrogen-nitrogen proportioning device can meet the stability of the concentration of hydrogen in nitrogen during debugging under the condition of stable pressure and flow, once the flow and pressure at the use end change greatly, the concentration of hydrogen in nitrogen will decrease. A great change occurs in an instant, and it cannot meet the customer's use requirements. And it takes a long time for the concentration to stabilize again. Thus wasting a lot of time and gas! Waste of labor and energy. Therefore, we provide an intelligent automatic hydrogen-nitrogen proportioning device. Contents of the i...
