Dissolubility stickum will fail, and so as to which fire-retardant absorbent article 6 will fall, fall on breather valve 1, it is readily appreciated that, fire-retardant suction
The size of aquatic product 6 is far longer than the size of breather valve 1, so will play the role of closing breather valve 1, so as to completely cut off flame
Contact with air, achievees the purpose that fire extinguishing.
PLC controller 4 carries out water spray according to the flame of breather valve 1 control water injector and includes：It is sent out in flame detector 22
When going out flare up fire, the control of PLC controller 4, which is opened second solenoid valve 34 and water pump 32 and passed through, tilts nozzle 332 to fire-retardant suction
Aquatic product 6 is sprayed water.Wherein, fire-retardant absorbent article 6 can be felt 6.
To sum up, optimal technical scheme provided by the utility model is summarized as follows：
In the upper end set temperature sensor 21 of breather valve 1, flame detector 22 is set at the gas outlet of breather valve 1,
One supporting rack 5 is set, which includes four steel columns and top steel plate, and top and the top steel plate of four steel columns weld, and four
The bottom of root steel column is welded on the top of crude oil storage tank, and four steel columns are divided into two groups by diagonal, one of which diagonal
Two steel columns on arrange horizontal drencher 331, arranged on another group of cornerwise two steel column tilt upward water curtain spray
First 332, horizontal drencher 331 and the drencher 332 that tilts upward respectively with the first solenoid valve 31 and second solenoid valve 34
Connection, the first solenoid valve 31 and second solenoid valve 34 connect with water pump 32.The top lower surface of steel plate of supporting rack 5 passes through water-soluble
Property glue has been bonded felt 6.
When the temperature that temperature sensor 21 measures is more than 50 DEG C, 32 and first electromagnetism of water pump is opened in the control of PLC controller 4
Valve 31 opens horizontal drencher 331, breather valve 1 is cooled down；When the temperature that temperature sensor 21 measures is less than 50 DEG C
When, the control of PLC controller 4 switches off the pump 32 and first solenoid valve 31.
When flame detector 22 monitors flame and sends out flare up fire, water pump 32 and the are opened in the control of PLC controller 4
Two solenoid valves 34 open the drencher 332 tilted upward, i.e., spray water to felt 6, and felt 6 absorbs large quantity of moisture, due to
Connection medium between felt 6 and the top steel plate of supporting rack 5 is water soluble glue, so absorbing large quantity of moisture in felt 6
When water soluble glue can be also quickly invalidated due to water suction, fall so as to felt 6, fall on breather valve 1, due to the ruler of felt 6
The very little size for being far longer than breather valve 1 so as to play the role of closing breather valve 1, has completely cut off contact of the flame with air, so as to
Realize fire extinguishing.
