Automatic fire extinguishing device for mine area

The automatic fire extinguishing device in mine area is suitable for the underground coal mine with explosive dangerous gas and coal dust, mainly used in the shaft, belt conveyor, electromechanical room, substation, gas extraction room, underground inclined roadway lifting electrical equipment or cable and other places with potential fire hazards; The device detects the flame or smoke signal in time at the initial stage of the fire, and extinguishes the fire source in time to prevent a wider range of more serious fire accidents caused by it. The device can be equipped with different terminal equipment according to the type of fire within the installation protection range, which can put out mechanical, electrical and chemical fires. The water, dry powder and heptafluoropropane used in the fire extinguishing device have no corrosion to the protective substances, and can quickly extinguish the fire source in the area in the way of full flooding.

DESCRIPTION

Product use

The automatic fire extinguishing device in mine area is suitable for the underground coal mine with explosive dangerous gas and coal dust, mainly used in the shaft, belt conveyor, electromechanical room, substation, gas extraction room, underground inclined roadway lifting electrical equipment or cable and other places with potential fire hazards; The device detects the flame or smoke signal in time at the initial stage of the fire, and extinguishes the fire source in time to prevent a wider range of more serious fire accidents caused by it. The device can be equipped with different terminal equipment according to the type of fire within the installation protection range, which can put out mechanical, electrical and chemical fires. The water, dry powder and heptafluoropropane used in the fire extinguishing device have no corrosion to the protective substances, and can quickly extinguish the fire source in the area in the way of full flooding.

With the corresponding sensors such as smoke sensing, flame, -carbon oxide, and optical fiber temperature measurement, the intelligent perception judges the development trend of the hidden danger of the equipment, and when the hidden danger (monitoring data) develops to the preset point, the early warning is carried out and the fire prevention measures such as sprinkling fire extinguishing agent and spraying dry powder fire extinguishing agent are taken.

System composition

The device is composed of mine flameproof and intrinsically safe programmable control box, mine flameproof and intrinsically safe electric control box, coal mine carbon oxide sensor, mine intrinsically safe electric ball valve, mine intrinsically safe smoke sensor, mine flameproof and intrinsically safe breaker, mine flameproof and intrinsically safe regional fire extinguishing device host, dry powder fire extinguisher and well monitoring host, etc.

Main feature

Based on multi-sensor information fusion technology, real-time collection of temperature, smoke and flame information in the protected area, when the temperature, smoke concentration and flame intensity exceed the set value, the controller controls the fire extinguishing and explosion suppression device to perform spraying action, while the sound and light alarm, fire extinguishing agent through the transmission pipeline evenly sprayed in the protected area, so as to achieve the purpose of automatic and rapid fire extinguishing and explosion suppression in the area;

The system can set multiple partitions, each partition can be preset temperature alarm value;

PLC control box has high programmability and scalability, can expand I/O0 interface, easy access to other types of sensors and equipment;

Different kinds of fire extinguishing agents can be used for different fires. Dry powder fire extinguishing, gas fire extinguishing, water spray fire extinguishing and other fire extinguishing agents can be selected.

The system provides standard communication interface, can realize centralized monitoring of dispatching center, can realize seamless docking with smart mine platform, and truly realize unattended;

With stable performance: ensure long-term work error-free action, open quickly, reliable quality;

When the upper computer or underground ring network is faulty, the regional fire extinguishing device can operate independently.

The host is equipped with a display screen and manual control function, and the on-site staff can choose to manually operate the fire extinguishing according to the on-site situation;

With automatic fault detection function;

With early warning function, it can achieve alarm according to the temperature, carbon monoxide, smoke detection results, and early warning according to the change of temperature and growth rate.
