PFH automatic fire extinguishing device and mine area automatic fire extinguishing system are an efficient, intelligent and environmentally friendly automatic fire extinguishing equipment targeted at the head/tail of coal mine belt conveyor, chamber, transformer, cable trench, air compressor and high and low pressure cabinet. The fire extinguishing device uses perfluorohexanone as the fire retardant, which can quickly reduce the fire, efficiently extinguish the fire and avoid the re-ignition of the fire.

In the past, the detection method of traditional fire extinguishing method was mainly manual observation, which had the disadvantages of untimely fire detection, poor timeliness of fire extinguishing and low efficiency of fire extinguishing. The PFH automatic fire extinguishing device/system adopts intelligent fire detection technology, controls the start of the fire extinguishing device according to the temperature, flame and other signals monitored in the protection area, and realizes automatic unattended fire extinguishing, making the fire extinguishing more timely, accurate, efficient and intelligent.

Perfluorohexanone is a liquid at normal temperature. Because its heat of evaporation is only 1/25 of that of water, and its vapor pressure is 25 times that of water, these properties make it easy to vaporize and exist in a gaseous state, and can achieve good fire extinguishing effect relying on heat absorption. At the same time, perfluorohexanone has good electrical insulation and non-corrosivity, which can extinguish fire, reduce temperature and inhibit re-combustion while minimizing the damage to the head/tail of the belt conveyor in the coal mine.

Features of PFH automatic fire extinguishing device:

1. The device has simple structure, convenient installation, does not occupy too much space, and can effectively reduce the floor area and production costs.
2. The electrical insulation of perfluorohexanone makes it the most advantageous in fire extinguishing in the field of electric power, and there is no electrification.
3. Perfluorohexadone fire extinguishing agent is safe, environmentally friendly, low toxic, non-polluting after use, leaving any residual traces, and does not require additional cleaning in the later stage.
4. The device has the function of manual and automatic control switching, which can realize automatic detection and fire extinguishing, and can also manually control and start fire extinguishing according to actual needs.
5. The device has a 24-hour uninterrupted protection function and is equipped with an emergency start module to ensure the normal and stable operation of the device under power failure.
