5. Fire fighting

5 1 fire fighting design /#51 fire fighting design firefighting system components the firefighting system is designed according to the specification and size of the 1 6mw/3 008mwh 20 foot container the fire extinguishing agent is transported from the fire extinguishing agent cylinder group through the main pipe and branch pipe to the nozzle of the container battery room to achieve the fire extinguishing function the system includes gas cylinder, fire extinguishing agent, solenoid valve, pressure feedback device, firefighting control system, etc the fire control system is mainly composed of fire detector (temperature and smoke), audible and visual alarm device, emergency start and stop button, air release indicator, fire controller, etc the combustible gas detector is separately configured to detect the concentration of hydrogen and carbon monoxide in the battery room, and the signal is transmitted to bess at the same time, the container is equipped with pressure relief device, air inlet and exhaust fan firefighting system action logic this system has two control modes automatic and electrical manual there are two independent detection circuits in each protection area when the first fire signal is given, an alarm will be issued, indicating the location of the fire and reminding the staff to pay attention when the first 2 detector also signal fire, automatic fire extinguishing controller began to delay phase (0 to 30 s adjustable), after a time delay, open the solenoid valve, solenoid valve needle start bottle storage cylinder head valve, the fire area firefighting operations, at the same time receive the feedback signal from the pressure switch alarm controller, control panel discharge indicator; when the alarm controller is in the manual state, the alarm controller only sends out alarm signals and does not output action signals after the on duty personnel confirm the fire alarm, press the emergency start button on the alarm control panel or the emergency start and stop button at the entrance of the protection area to start the system and spray fire extinguishing agent \\ 5 2 coupling fire brigade the water fire protection pipeline is located on the side of the container, claw pitch size 81 when there is a fire inside the system, the container can be cooled down through the water interface location of water firefighting interface the water fire protection pipe interface is located on the side of the container, with the top being the inlet and the bottom being the outlet, claw pitch size 81 when there is a fire inside the system, the container can be cooled down through the water interface attention should be paid to the external sealing of the water fire pipe interface to maintain the temperature of the battery room water firefighting interface 5 3 fire controller /#53 fire controller 5 4 fire alarm and detection system /#54 fire alarm and detection system 5 4 1 temperature detector /#541 temperature detector 5 4 2 alarm bell /#542 alarm bell 5 4 3 acousto optic alarm /#543 acousto optic alarm 5 4 4 gas release indicator /#544 gas release indicator
