How a Nitrogen Generator Membrane Works
Pressurized air is fed to one end of the hollow fiber membranes. Membranes contain a bundle of hollow fibers with holes small enough to allow the smaller oxygen molecules to exit through them under pressure. The permeation rates of water vapor, CO2, and oxygen contained in the air stream are faster than nitrogen and argon and will rapidly diffuse through the fiber walls. The slower diffused nitrogen molecules remain in the fiber bore and are collected as the nitrogen product gas. The air flow rate will determine how much undiffused oxygen remains with the nitrogen gas. The nitrogen product gas is extremely dry, with atmospheric dew points typically below -40°F. The membranes act like a filter with no moving parts and continuously generate nitrogen at selected flow and purity.
Safety Features
1.Equipped with temperature control system: to ensure that the temperature of the compressed air entering the membrane system is constant. When the temperature exceeds the set value, the heater can be automatically cut off to protect the membrane module. Membrane insulation sleeve heating adopts PTC with tropical automatic temperature limiting, protective film group.
2. Equipped with an inlet and outlet pressure interlock switch: When compressed air entering the membrane system is interrupted or the air pressure is lower than a certain set value, the heater can be automatically turned off to protect the membrane group and the heater.
3.Nitrogen purity control system: The oxygen analyzer can ensure the accurate display of the nitrogen content of the product, ensure the system is safe and reliable, and the nitrogen purity of the product can be continuously adjusted between 90% -99%. The nitrogen produced by this equipment can reach the qualified purity within 5 minutes after startup. It is equipped with an automatic vent valve. When the purity of the product gas exceeds the set value, the unqualified nitrogen is automatically discharged to the atmosphere immediately, ensuring the user's requirements. Nitrogen is not contaminated.
4.The safety relief valve can protect the pressure vessel from overpressure.
5.All pressure vessels, high-pressure pipe fittings and valves shall be provided with the certification of pressure vessel management department.
