Industrial Hollow Separation Membrane Fiber Nitrogen Production
Industrial hollow separation membrane fiber nitrogen production systems utilize advanced membrane separation technology for efficient nitrogen generation.
Working Principle
Membrane separation nitrogen generators leverage the permeability and diffusivity properties of air components to separate nitrogen from air. When air passes through the membrane under differential pressure conditions, oxygen, CO₂, and water vapor permeate rapidly and are discharged through low-pressure points, while nitrogen permeates slowly and is collected at high-pressure points, achieving effective oxygen-nitrogen separation.
Main Features

Usage Precautions and Safety Measures
Usage Precautions
Installation Environment
Equipment should be placed in ventilated, dry areas with level ground, away from corrosive gases and dust pollution. Avoid direct sunlight, rain, and low-temperature freezing environments while ensuring adequate maintenance space around the equipment.
Gas Source Requirements
Connected compressed air must be fully filtered and dried. Gas containing significant oil, water vapor, or impurities is strictly prohibited from entering membrane modules to prevent hollow fiber membrane blockage and corrosion, avoiding performance degradation and extending equipment service life.
Operating Specifications
Operate strictly according to equipment rated pressure, flow rate, and standard parameters, avoiding overpressure and overload operation. Follow standard startup and shutdown procedures without frequent equipment cycling. Non-professional personnel should not disassemble pipelines, membrane components, or control parts without authorization.
Routine Inspection
Regularly check pipeline interfaces and valves for leaks, confirming all instruments display normal data. Monitor equipment operating sounds and running status. If abnormalities are detected, stop immediately for inspection and troubleshooting—do not operate equipment with potential faults.
Storage and Shutdown Management
For long-term shutdown, drain residual air from equipment and pipelines, implementing proper dust-proof measures. Before reuse, conduct comprehensive inspection of all pipelines and components, proceeding to formal operation only after stable, normal trial run.
Safety Guarantees
Gas Safety
Nitrogen is an inert gas. Working areas must maintain proper ventilation to prevent excessive nitrogen accumulation and ensure normal air circulation. Maintain well-ventilated working environments during extended equipment operation.
Electrical Safety
Equipment circuits and wiring require waterproof and anti-aging protection with intact, reliable grounding devices. Completely cut main power before equipment maintenance to avoid live operation and eliminate electrical contact risks.
Standard Operation Protection
Equipment must be used in compliance with applicable industry standards and working conditions. Supporting pipelines and valves should match equipment specifications. Unauthorized modification and disassembly are prohibited to ensure stable, safe operation.
Emergency Response
Prepare basic maintenance and emergency tools. In case of gas leakage, abnormal pressure, unusual operating noise, or other faults, stop immediately and cut off air source and power. If discomfort occurs due to poor air circulation, move immediately to well-ventilated area for rest.
Personnel Management
Operators must be familiar with equipment performance and operating safety specifications. Do not stack sundries or irrelevant items around equipment, keeping operation and maintenance passages unobstructed to ensure stable equipment operation.
