Application of Foam Spray Fire Extinguishing System in Power System

2012-11-22

Abstract: The foam spray fire extinguishing system uses high-efficiency synthetic foam liquid as a fire extinguishing agent, and sprays it onto the fire extinguishing object under a certain pressure through a special atomizing nozzle to quickly extinguish the fire. It is a fire extinguishing system especially suitable for power transformers. This paper mainly makes a brief description of the structure, working principle and design application of the system.

Aerosol Fire Extinguishing Technology

2012-11-22

Aerosol fire extinguishing agent is a new type of fire extinguishing agent developed in the past forty years. It is a solid mixture composed of oxidizing agent, reducing agent, burning rate control agent and binder. The release of hot aerosol fire extinguishing agent has undergone a combustion reaction, and the product contains both solid and gas. Most of them are fire extinguishing gases such as N2, CO2 and water vapor, and the solid particles are oxides of potassium and strontium. When the release product is cooled and condensed, it will generate extremely fine particles, the diameter of which is generally less than 0.45 microns. These extremely fine particles can efficiently absorb and neutralize the combustion free radicals in the flames, thereby achieving chemical inhibition of fire extinguishing. The aerosol formed by the solid particles wrapped in the fire extinguishing gas can be suspended for a long time, and can bypass obstacles and spread to every corner, effectively extinguishing the fire in a fully submerged manner. Simply put, aerosol fire extinguishing agent is a kind of micro-nano-scale dry powder particles that can be suspended in the air. It is the crystallization of the development of pyrotechnic technology and nanotechnology.

Research and Application of Polymer Coal Dust Prevention and Dust Suppression Flame Retardant

2012-11-22

Coal dust is one of the major disasters that have plagued coal mine safety production for a long time. It is not only prone to pneumonia, but long-term inhalation can also lead to pneumoconiosis. Pneumoconiosis has become the number one occupational disease in my country. In order to reduce the hazards of coal dust and protect the safety of coal mine production, the research team formed by Shandong University of Science and Technology successfully developed a new type of coal dust flame retardant after repeated experiments on the basis of in-depth research on the physical and chemical characteristics of coal dust and the wetting mechanism. According to reports, using the original dust suppression equipment in the coal mine, adding this coal dust flame retardant to the dust-proof water and spraying it can not only effectively capture the coal dust and inhibit the secondary flying of the coal dust, but also prevent the coal dust from burning and burning. ****, Improving the operating environment of coal mines and improving the disaster resistance of coal mines are of great practical significance to the safe production of coal mines.

New Technology Application of Fire Motor Pump

2012-11-22

The motorized fire pump is a fire pump directly connected with a light engine and a water pump, which can be moved or fixed by manpower, and is used to fight general material fires and small oil fires. Because the motor pump has the advantages of lightness and flexibility, and is not restricted by traffic, electric power, and regional obstacles, it has been widely used to rescue industrial and mining enterprises, warehouses, ports, docks, and rural areas where the road traffic conditions are poor and fire trucks are difficult to pass or cannot arrive in time. The first fire in the place.

"Million Yuan Fire Truck" Airport Drill Shows Its Power

2012-11-22

At 10 o'clock on the 5th, a simulation exercise was held at Taiping International Airport: a light aircraft had an "accident" when it landed. Due to a loss of control, it entered the main channel, the hatch could not be opened, and thick smoke came out from the tail. In less than 3 minutes, a brand-new fire truck arrived at the scene, pulled the noose, started the smoke machine, and took out a toothless saw to cut open the hatch...The fire fighters used this fire truck to complete the first fire within 7 minutes. "Rescue"******.
