Abstract

The invention provides pressure swing adsorption nitrogen production equipment, which comprises a control system, an air compression 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, and the detection system comprises a detection mechanism, a first buffer tank and a standby purification mechanism; the detection mechanism is used for detecting the humidity and the particulate matter concentration in the gas output by the purification system, the detection mechanism comprises adetection tank, the first buffer tank is connected with the output end of the purification system, and the input end of the detection tank is connected with the output end of the first buffer tank. According to the invention, the purification effect of the purification system can be automatically detected, and the standby purification mechanism is added, so that the nitrogen making process can bealways kept in operation, and the problems that the adsorption equipment is easily damaged and the continuous operation capability is not good enough due to the fact that the existing pressure swing adsorption nitrogen making equipment does not monitor the purification effect in time are solved.

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...
