Principle: The pressure swing adsorption nitrogen generation unit uses clean compressed air as the raw material and carbon molecular sieve as the adsorbent, operating on the principle of pressure swing adsorption to produce nitrogen at room temperature. Based on the differences in the adsorption capacity of oxygen and nitrogen on the surface of the carbon molecular sieve and their varying diffusion rates within the sieve, the programmable logic controller (PLC) controls the opening and closing of the programmed valves to achieve the processes of pressurization adsorption and depressurization desorption, thereby separating oxygen and nitrogen to obtain nitrogen of the desired purity. Features: 1. Fast startup time, capable of delivering qualified nitrogen within 15 to 30 minutes; 2. Fully automated operation, enabling unattended operation throughout the entire process; 3. Efficient molecular sieve packing, tighter and denser, resulting in a longer service life; 4. Stable and adjustable pressure, purity, and flow rate to meet various customer needs; 5. Reasonable structure, advanced process, safe and stable operation, with low energy consumption; Applications of Nitrogen Generators Metal Heat Treatment: Bright quenching and annealing, carburizing, controlled atmospheres, powder metal sintering; Chemical Industry: Blanketing, inert gas protection, pressure transmission, nitrogen purging for paints and coatings; Petroleum Industry: Nitrogen drilling, well maintenance, refining, natural gas recovery; Fertilizer Industry: Raw material for nitrogen fertilizers, catalyst protection, purge gas; Electronics Industry: Large-scale integrated circuits, electronic components, and semiconductor processing; Food Industry: Food packaging, beer preservation, non-chemical sterilization, fruit and vegetable preservation; Pharmaceutical Industry: Nitrogen packaging, transportation and protection of pharmaceuticals, pneumatic conveying of materials; Coal Industry: Coal mine fire prevention and extinguishing, gas displacement during coal mining; Rubber Industry: Cross-linked cable production and anti-aging protection for rubber products; Glass Industry: Gas protection in float glass production; Cultural Relic Preservation: Anti-corrosion treatment and inert gas protection for unearthed relics, calligraphy and paintings, bronze ware, silk fabrics, etc. Technical Specifications Feed Air: Product Nitrogen: Pressure——6～10bar Dew Point——≤10℃ Oil Content——≤0.003mg/m3 Air Flow——Varies with nitrogen flow and oxygen content Pressure——≤9bar Dew Point——≤－40℃ Purity——95%～99.99% Nitrogen Flow——1～5000Nm3/h Note: For lower oxygen content and specific requirements, the SLCDC series nitrogen purification equipment can be optionally configured.
