The explosion-proof nitrogen generator system for chemical reactor protection is special safety supporting equipment for chemical production scenarios, which is mainly used for nitrogen sealing, oxygen isolation, pressure maintaining and explosion suppression of chemical reaction kettles. Most chemical raw materials and reaction intermediates are flammable, explosive and oxidizable. Mixing with air and oxygen is easy to cause combustion, explosion and material deterioration. The explosion-proof nitrogen system provides continuous inert nitrogen atmosphere for the closed reaction kettle, isolates oxygen in the air, eliminates potential safety hazards in the reaction process, and ensures the safe and stable operation of chemical production.

The whole system adopts full explosion-proof grade configuration, meeting the Ex d II BT4 explosion-proof standard required by chemical explosion-proof areas. All electrical components including control box, pneumatic valve, sensor, power switch and motor are explosion-proof customized products, with sealed and isolated structure, which can avoid electric spark generation and prevent explosion accidents caused by electrical contact ignition in flammable and explosive chemical environments. The equipment body adopts anti-static and anti-corrosion design, the shell is made of thickened explosion-proof carbon steel, and the internal pipeline is treated with anti-corrosion coating, which can adapt to corrosive gas and humid environment in chemical workshops and avoid equipment aging and failure caused by chemical corrosion.

In terms of system operation function, the explosion-proof nitrogen generator has automatic pressure monitoring and linkage protection functions. According to the pressure and oxygen content parameters inside the chemical reactor, the system automatically adjusts the nitrogen output flow and pressure, realizes automatic nitrogen supplement and pressure maintaining, and keeps the internal oxygen content of the kettle below the safe threshold for a long time. When the system has abnormal pressure, pipeline leakage or equipment failure, the explosion-proof alarm device will automatically trigger sound and light alarm, and cut off the gas supply and power supply in time to ensure production safety. The equipment runs stably for 24 hours, with high nitrogen purity and stable inert protection effect, which is widely applicable to pharmaceutical chemical, fine chemical, petrochemical and other reactor production scenarios.
