1. Features and uses of the product
The ZFP dry powder fire extinguishing device uses nitrogen as the power to provide pressure to the dry powder tank, push the dry powder fire extinguishing agent, and transport it through pipelines to dry powder cannons or dry powder guns to extinguish solid, oil, gas and electrical fires.
The device is suitable for flammable and explosion-proof places such as dangerous goods warehouses, liquefied gas equipment, large quenching oil tanks, gas stations, large indoor and outdoor transformers, oil pipelines, natural gas wells, oil tank trains, petrochemicals, etc.
2. Working Principle
The fire extinguishing device is filled with dry powder fire extinguishing agent. Dry powder fire extinguishing agent is a dry and easy-flowing fine powder used for fire extinguishing. It is composed of inorganic salts with fire extinguishing efficiency and a small amount of additives that are dried, crushed and mixed to form a fine solid powder. It is a fire extinguishing agent that is widely used in fire fighting and is mainly used in fire extinguishers. In addition to the special dry powder chemical fire extinguishing agent for extinguishing metal fires, dry powder fire extinguishing agents are generally divided into two categories: BC dry powder fire extinguishing agent and ABC dry powder. Dry powder fire extinguishing agent mainly extinguishes fire through the physical and chemical effects that occur when the powder mist sprayed under the action of pressurized gas contacts and mixes with the flame. In addition, it also has the functions of partially diluting oxygen and cooling.
When a fire occurs, open the nitrogen bottle head valve, reduce the pressure through the pressure reducing valve, and then provide pressure to the dry powder tank to push the dry powder fire extinguishing agent and transport it through the pipeline to the dry powder cannon or dry powder gun for fire extinguishing.
