2023-07-21
In response to the national environmental protection policy, most of the open coal fields have been transformed into fully closed coal fields, and the inflatable membrane coal shed is one of the new coal field closure methods.
The main body of the building of the air film coal shed is a high-strength membrane, the use of air pressure to hold up the membrane body, it forms a large span of closed space without beams and columns, very suitable for coal production, storage and transport work. Air membrane manufacturers of this closed air membrane coal shed can withstand wind, frost, rain and snow, but also to avoid dust leakage, to meet the environmental requirements.
Of course, as an indoor coal storage place, the fire safety issue cannot be ignored. Although the air membrane building code does not make clear provisions for fire fighting, but for safety considerations, the air membrane manufacturer Beijing Xinyuan Yijia Membrane Structure Technology Co., Ltd. will design the fire fighting system accordingly to the actual situation of the coal shed. The design of the fire fighting system refers to the Design Code for Fixed Fire Cannon Fire Extinguishing System GB50338-2003 and Automatic Tracking and Positioning Jet Fire Extinguishing System GB25204-2010.
The fire-fighting equipments used in the air-membrane coal shed are all explosion-proof, and the fire-fighting device is an integrated equipment of early fire detection, fire-linkage alarm and mechanical transmission fire-fighting. The fire water cannon can realise the function of automatic/manual fixed-point control of fire extinguishing for large space fire. It has the advantages of long control distance, large fire protection area, fast response speed, flexible installation, convenient maintenance and high reliability. Automatic fire cannons can be computer technology, image-based fire detection technology and red-ultraviolet sensing technology, mechanical transmission technology and image transmission technology into one, all-weather automatic monitoring range for active detection.
When the fire extinguishing device detects the fire, it will start the fire extinguishing system in time, locate the position of the fire source, open the motorised valve, send the alarm signal to the alarm host, start the fire pump to carry out the fixed-point water spraying to extinguish the fire, and stop automatically after the fire is extinguished. In case of re-ignition, the system will restart to ensure the safety of the coal shed.
