Technical principle of box type PSA nitrogen generator

The equipment relies on the principle of pressure swing adsorption (PSA) and air separation for nitrogen production, using high-quality carbon molecular sieves as the adsorption medium.
Compressed clean air is introduced into the adsorption tower. Under pressure, molecular sieves preferentially adsorb impurities such as oxygen and carbon dioxide in the air, while nitrogen cannot be adsorbed and can be retained and separated; During the decompression process, the adsorbed oxygen is desorbed and discharged, and the molecular sieve completes the regeneration cycle.
Two towers alternate between adsorption and desorption processes, continuously producing high-purity nitrogen gas with a stable purity of 99.999%, which meets the gas standards for SMT precision welding processes. The enclosed box structure of the whole machine isolates external impurities, ensuring stable and efficient nitrogen production process.

Main Feature

1.The material source is from the nature, the systemonly needs compressed air and power, so the cost ofpower and operation is less.

2.Nitrogen purity is easy to adjust, it is only affectedby the capacity, purity of normal nitrogen is at the rangeof 95%-99.99%(can be adjusted), purity of high nitrogenis at the range of 99%~99.999%( can be adjusted)

3.The system is automatic, quick starting and noneed to monitor. One button for start and stop, run 10-15minutes to generate the N2 air.

4.The working progress is easy, the configuration iscompact, the landing space is less and the environmentis wel-adapted.

5.Snow storm filling can avoid the damage of CMS.6.Digital flow meter has pressure compensation, it ishighly precise meter which can monitor the progress, itcan test quick flow and accumulate the total capacity.

Precautions for safe use of box type PSA nitrogen generator
1. Installation and Environmental Safety
Venue requirements: The equipment must be placed in a well ventilated, dry, and clean indoor environment, away from open flames, heat sources, corrosive gases, and dust sources. The ground must be level and load-bearing, with sufficient space reserved for maintenance and heat dissipation.
Power supply and grounding: Wiring must be done according to the rated voltage of the equipment, with reliable grounding to avoid voltage instability and leakage risks; It is strictly prohibited to connect wires privately or randomly, and the distribution box must be equipped with overload and leakage protection devices.
Pipeline and connection: Before installation, check all air pipes and valves for damage or air leakage, and conduct an air tightness test after connection; It is strictly prohibited to use unqualified or expired pipeline fittings to avoid nitrogen leakage.
2. Pre startup safety check
Status confirmation: Check whether the box door is completely closed and locked, confirm that there is no accumulation of debris inside the equipment, the cooling fan and temperature control system are normal, and there are no fault alarms.
Parameter verification: Confirm that the intake pressure, equipment set pressure, and purity parameters are all within the rated range, and that the pressure regulating valve and safety valve are in standard working condition.
Personnel preparation: Operators must be familiar with the equipment operating procedures and are strictly prohibited from operating without a license or violating regulations; Clean the surrounding area of the equipment before starting up, and prohibit stacking flammable materials.
3. Safety standards for operation process
Operation monitoring: During equipment operation, it is necessary to regularly observe instrument data such as pressure, purity, and temperature. If there is a sudden change in pressure, abnormal purity, or abnormal noise or odor, the machine should be stopped immediately for troubleshooting.
Prohibited illegal operations: It is strictly prohibited to open the box door or touch the internal high-temperature/high-pressure components during operation. It is also prohibited to modify equipment parameters or disassemble safety protection devices without authorization.
Nitrogen leakage protection: Nitrogen is an inert gas, and leakage can reduce the oxygen content in the environment. If a leakage is found, the machine should be immediately shut down for ventilation, and personnel should evacuate to a safe area. Treatment can only be carried out after the oxygen content returns to normal.
4. Maintenance and repair safety
Power off and pressure relief priority: Before any maintenance or repair operation, the power must be cut off, the internal pressure of the equipment must be evacuated, and there must be no residual gas before opening the box door for operation.
Standardize maintenance process: replacement of consumables such as filter cartridges and molecular sieves should be carried out according to the instruction manual cycle, using original factory accessories; During maintenance, be sure to label and warn the equipment to prevent accidental startup.
Anti static protection: When conducting maintenance in dusty environments, it is necessary to wear an anti-static wristband to avoid safety hazards caused by static sparks.
5. Shutdown and long-term storage safety
Normal shutdown: During shutdown, gradually release pressure and turn off the power according to standard procedures. It is forbidden to directly shut down the machine to avoid damage to components caused by pipeline pressure impact.
Long term storage: If the equipment is not in use for a long time, the internal gas should be emptied, and it should be sealed for moisture and dust prevention. The status of pipelines and electrical components should be checked regularly to prevent moisture and corrosion.
