The fire extinguishing system for surface coal mining equipment is vital to ensure safe production and reduce fire losses in surface coal mines. The following is an introduction of this fire extinguishing system with reference to the related products of Zhongdao Fire Protection:
System Composition
Detection system: Adopting advanced temperature-sensitive, smoke-sensitive and flame detectors, it can conduct all-round real-time monitoring of the engine compartment, fuel tank, electrical equipment and other heat-prone and flammable areas of the mining equipment. It can accurately capture early fire signals such as abnormal temperature rise, smoke appearance and flame signs, providing the basis for rapid response to extinguish the fire.
Transmission System: Utilizing 5G network transmission technology and cloud computing processing technology, the fire data collected by the detector is quickly and accurately transmitted to the control system China supplier. Ensure the timeliness and stability of information transmission, not affected by distance and environmental interference.
Control system: the core intelligent control processor analyzes and judges the transmitted fire signals. When it is determined that a fire has occurred, it quickly issues an alarm and fire-fighting instructions, coordinates the work of various subsystems, and realizes automated and intelligent fire response.
Alarm system: Once the control system determines that a fire has occurred, the alarm system starts immediately and issues a high-decibel sound and light alarm signal. It not only reminds the on-site operators to evacuate and take countermeasures in time, but also sends alarm information to the monitoring center of the mine and relevant management departments so that rescue can be organized quickly.
Fire extinguishing system: Equipped with efficient water-based or perfluorohexanone fire extinguishing agent storage tanks and sprinklers. After receiving the fire extinguishing command, the fire extinguishing agent is sprayed precisely and evenly to the fire area through the customized pipelines and spray nozzles to achieve rapid fire extinguishing and effective fire control.
System Advantages
High sensitivity and fast response: The system is able to automatically capture extremely weak signs of fire and respond at the early stage of the fire. From the detection of fire to the start of the fire extinguishing device, the whole process takes a very short time, effectively avoiding the spread of fire.
Independent operation ability: the whole process of fire detection, alarm and fire extinguishing can be completed independently without personnel operation, which greatly improves the efficiency of fire extinguishing and reduces the influence of human factors, especially suitable for unattended mining equipment and harsh operating environment.
High-efficiency extinguishing agent: The water-based extinguishing agent is characterized by rapid fire extinguishing, good cooling effect and effective suppression of fire re-ignition; the perfluorohexanone extinguishing agent has the advantages of being colorless, odorless, non-toxic, non-conductive, and non-damaging to the equipment, and it can quickly extinguish the fires of A, B, C, and E categories.
Adapt to complex environment: all parts of the system are made of high-quality materials, pipes and fittings are treated with anti-corrosion, and the detectors and nozzles are dust-proof, water-proof and corrosion-proof. Able to operate stably and reliably in the harsh environment of high temperature, extreme cold, high dust, high vibration and high corrosion in open-cast coal mines.
Multiple start-up methods: automatic start-up, manual start-up and mechanical emergency start-up. Automatic start ensures timely response to fire when no one is aware of it; manual start facilitates manual intervention by the operator at the early stage of fire discovery; and mechanical emergency start serves as a back-up means in emergencies to ensure that the system can be activated normally under any circumstances.
Customized service: Individualized customized design can be carried out according to different types of mining equipment, structural characteristics, operating environment and customer's specific fire extinguishing needs. Including the choice of extinguishing agent, the arrangement of the number and position of nozzles, the type and number of detectors, etc., in order to ensure that the fire extinguishing system is perfectly adapted to the mining equipment, and to achieve the best fire extinguishing effect.
Application Scenario
The surface coal mining equipment fire extinguishing system can be widely used in surface coal mining equipment, such as mining dump trucks, loaders, shovels, excavators, crushers and so on. Whether in the process of equipment operation or in the shutdown state, it can provide a full range of fire protection, effectively reduce the risk of fire, safeguard the safety of equipment and personnel, and reduce the production disruption and economic losses caused by fire.
