How to activate the water spray fire suppression system in the ethylene tank farm? Automatic control scheme: When a fire breaks out, either the fire detection alarm activates or an inspector presses the manual alarm button, which sends the fire signal to the fire alarm control panel in the control room. Upon receiving this signal, the control panel automatically activates the solenoid valves connected to the deluge valve assembly, thereby opening the deluge valves and supplying water to the area where the fire is occurring. Once the fire has been extinguished, manually shut down the deluge valve assembly at the site. Manual start-up scheme in the control room: Manual operation buttons are provided on the fire alarm control panel. When the control panel receives a fire alarm signal, and after manual confirmation, the duty personnel can use these buttons to activate the solenoid valves on the deluge valve assemblies, thereby initiating the aforementioned fire extinguishing process. On-site manual activation scheme: In the event of a fire, operators can directly manually open the deluge valve assembly on site to carry out the aforementioned fire extinguishing process.
There are mainly three ways to activate the water spray fire suppression system in the ethylene tank farm: automatic control, manual activation from the control room, and manual activation on-site. In the automatic control mode, when a fire detector or a manual alarm button is activated, a signal is sent to the fire alarm control panel, which then automatically activates the deluge valve to supply water for extinguishing the fire ； Manual activation in the control room involves starting the fire extinguishing system manually via the buttons on the control panel, after a fire alarm is received and confirmed manually ； Manual activation on-site means that the operator directly opens the deluge valve at the site to extinguish the fire. After the fire is extinguished, the deluge valve assembly must be manually closed. .
