Pressure swing adsorption nitrogen production machine
Application
Nitrogen making equipment is widely used in electronics, food, metallurgy, electric power, chemical, petroleum, medicine, textile, tobacco, instrumentation, automatic control and other industries, as raw gas, protection gas, replacement gas and sealing gas.
Working Principle
pressure swing adsorption nitrogen equipment is the use of carbon molecular sieve as adsorbent, using pressure swing adsorption principle to obtain nitrogen equipment.Under A certain pressure, the use of oxygen in the air, nitrogen in carbon molecular sieve adsorption on the surface of the differences, namely carbon molecular sieve on the diffusion of oxygen adsorption than nitrogen, through programmable control of pneumatic valve opening and closing, alternate cycle, achieve A, B two tower pressure adsorption and vacuum stripping process, complete separation of oxygen and nitrogen, get high purity nitrogen.
Features
1. The equipment has compact structure, integrated skid-mounted, small footprint, no infrastructure and less investment.
2. Easy to start and stop, quick to start and produce gas.
3. Exquisite, low noise, no pollution, strong seismic performance.
4. Simple process, mature products, adsorption separation is carried out at room temperature, reliable operation, low failure rate, convenient maintenance, low cost.
After-sales Maintenance
1. each shift regularly check whether the exhaust muffler is emptied normally.
Exhaust silencer such as black carbon powder discharge indicates that carbon molecular sieve powder, should be shut down immediately.
3. clean the dust and dirt on the surface of the equipment.
4. Check the inlet pressure, temperature, dew point, flow rate and oil content of compressed air regularly normal.
5. Check the pressure drop of the air source connecting parts of the control air path.
Solution
1. PU pipes, pressure gauges, blowdown ball valves, pressure reducing valves and solenoid valves should be replaced according to their working environment and actual use. When PU pipes, pressure gauges, blowdown ball valves, pressure reducing valves and solenoid valves are cracked, aged or blocked, they should be replaced in time.
2 molecular sieve, activated carbon replacement should depend on its adsorption capacity and use time, after the life of the molecular sieve, there are more powder at the exit of the adsorption tower, and nitrogen capacity, active adsorption capacity should be considered when the replacement.Replacement, should not only replace part of the replacement, but all replacement, so as not to affect the adsorption effect.
3.The replacement of the filter element should depend on the pressure difference before and after the filter and the use time. When the replacement, it should not only replace part of it, but all of it, so as not to affect the oil removal effect.
