A pressure swing adsorption nitrogen production equipment

Abstract

The invention provides a pressure swing adsorption nitrogen production equipment, which includes a control system, an air compressor system, a purification system, an adsorption system and a gas storage system. A detection system is connected between the purification system and the adsorption system. The detection system includes a detection mechanism, a first The buffer tank and the spare purification mechanism, the detection mechanism is used to detect the humidity and particle concentration in the gas output by the purification system, the detection mechanism includes a detection tank, the first buffer tank is connected to the output end of the purification system, and the input end of the detection tank is connected to the first The output end of the buffer tank is connected. The invention can automatically detect the purification effect of the purification system, and add a spare purification mechanism so that the nitrogen production process can always keep running, so as to solve the problem that the existing pressure swing adsorption nitrogen production equipment is easy to damage the adsorption equipment if the purification effect is not monitored in time And the problem of not being able to continue to operate well enough.

Description

technical field [0001] The invention relates to pressure swing adsorption nitrogen production equipment, which belongs to the technical field of nitrogen production equipment. Background technique [0002] Pressure swing adsorption (referred to as PSA) is a new gas separation technology, which uses air as the raw material and uses a high-efficiency, high-selection solid adsorbent to selectively adsorb nitrogen and oxygen to remove nitrogen from the air. separated from oxygen. [0003] In the existing technology, the adsorption tower in the pressure swing adsorption nitrogen production equipment will have a purification device in front of it. The purification device is used to absorb moisture and particulate matter in the air, so that dry and clean air enters the adsorption tower for nitrogen and oxygen separation. , if the moisture-containing air enters the adsorption tower, it will make the adsorption tower humid, and it is easy to accumulate dust and cause blockage. It is...
