State controller 4.Emit and receive temperature information by using wireless mode, can avoid carrying out temperature information biography using wired mode
It is defeated to there is wiring complexity and easy be damaged in the event of fire of the wiring and lead to not effectively transmit temperature information
Problem.
Specifically, now explaining by taking the crude oil storage tank under fire condition as an example provided by the present invention for crude oil storage tank
Boiling-over proof control process.Since containing water and its relative density is less than the density of water, therefore the moisture in crude oil can be gradually in crude oil
Gather in crude oil storage tank bottom, once fire occurs, crude oil temperature can be increased constantly, former when temperature reaches crude oil burning point
Oil starts the heat wave that burns and generate, and heat wave is gradually moved to crude oil storage tank bottom, since heat wave temperature is much higher than the boiling point of water, therefore
It is water that heat wave can be such that crude oil storage tank bottom gathers, and a large amount of steam will pass through crude oil and float to liquid level, is moving up
The bubble of oily packet gas is formed in the process, i.e. oily a part forms the foam containing a large amount of vapor bubbles.In this way, necessarily making original
Oil volume expansion, outward overflow, while the crude oil of the not formed foam in part also by steam expansion power below dish out crude oil oil
Outside tank, keep crude oil liquid level wild, so as to cause the generation of boil-over phenomenon.In the present embodiment, production is boiled in initiation
Critical condition is boiled in initiation described in raw conditional definition, and essentially, it is when the control that critical condition is boiled in the initiation
The read liquid component information of device 4 processed and temperature information when meeting this condition the crude oil storage tank 100 generation boil over.For example,
The initiation boils over critical condition and is greater than preset temperature and liquid comprising the temperature maximum of 100 tank body of crude oil storage tank and top
Body ingredient is water.Inventor considers the problem of crude oil burning point, therefore the present embodiment will cause the default temperature boiled in critical condition
Degree is set as 60 DEG C, and certainly, the present invention is not limited to above-mentioned preset temperature, other temperature needed due to safety concerns are also
It can be applicable in.
In the present embodiment, the liquid component information of 21 pairs of 100 tank bottoms of crude oil storage tank of the probe is surveyed in real time
Amount, and its measurement result is sent to the controller 4；When there is fire generation, the tank body of the crude oil storage tank 100 and top
Temperature it is higher and higher, the tank body of the crude oil storage tank 100 and the temperature information on top are monitored by the thermal imaging system 10, it is described
The temperature information can be encoded and be emitted by transmitter 5, and the receiver 6 is after receiving the temperature information, to this
Temperature information is decoded and sends it to the controller 4；Finally via the controller 4 to liquid component information and
Temperature information is read out analysis, and when the two, which meets initiation, boils over critical condition, the controller 4 controls the solenoid valve 8
It opens, is drained with opening the drainpipe 7, the danger that can timely and effectively prevent crude oil storage tank 100 from boiling over.Example
Such as, when temperature maximum is greater than 60 DEG C and the liquid component of tank bottom is water, have and cause what the generation of crude oil storage tank 100 was boiled over
Danger, the controller 4 controls the solenoid valve 8 and opens at this time, controls the drainpipe 7 and drains, prevents the hair boiled in time
It is raw.With the rescue of live fire, fire has been put out, when temperature maximum is less than 60 DEG C, or when the moisture of tank bottom is whole
Discharge, when liquid component is oil, as long as meeting any of the above condition, the controller 4 controls the solenoid valve 8 and closes, control
The drainpipe 7 stops draining.
Specifically, temperature maximum is likely to occur during fire attack greater than 60 DEG C, but liquid component is the feelings of oil
Condition, the crude oil storage tank 100, which will not generate, at this time boils over, and the controller 4 controls the solenoid valve 6 and closes, the drainpipe 7
Stop draining；But with the application of fire water and foam, moisture can be gathered again in the bottom of the crude oil storage tank 100, at this time
Meet to cause and boil over critical condition, i.e., it is two conditions of water, the control that temperature maximum, which is greater than 60 DEG C and the liquid component of tank bottom,
Device 4 processed controls the solenoid valve 8 and opens, and controls the drainpipe 7 and drains.The controller 4 can monitor the initiation boiling in real time
Critical condition of overflowing then controls 1 row of drainage arrangement once meeting critical condition (two conditions while meeting critical condition)
Water, exclusion crude oil storage tank 100 is issuable in time boils over hidden danger, ensures the safety of life and property.
In conclusion the present invention creatively drains control measure, i.e. automatic trigger and control using most effective tank bottom
Drainage arrangement, it can be achieved that effectively controlled boiling over of may occurring of crude oil storage tank, thus ensured human life with
The safety of property.
Correspondingly, as shown in fig. 6, the present invention also provides a kind of boiling-over proof control method for crude oil storage tank, the control
Method includes: to acquire the liquid component information of the tank bottom of the crude oil storage tank；Acquire tank body and the top of the crude oil storage tank
Temperature information；And the liquid component information and tank body and the temperature information on top of the tank bottom of the reading crude oil storage tank, and
Meet to cause and boil under critical condition, the moisture of the tank bottom of the crude oil storage tank is discharged in control.
The present invention passes through the liquid for acquiring the tank bottom of the crude oil storage tank in real time for the boiling-over proof control method of crude oil storage tank
Body composition information and tank body and the temperature information on top further read the liquid component letter for the tank bottom for analyzing the crude oil storage tank
Breath and tank body and the temperature information on top meet under critical condition is boiled in initiation with temperature information in the liquid component information and control
The moisture of the tank bottom of the crude oil storage tank is discharged in system.
Wherein, it includes both following that critical condition is boiled in the initiation: temperature maximum is greater than preset temperature；And liquid
Ingredient is water.Inventor considers the problem of crude oil burning point, therefore the preset temperature in critical condition is boiled in initiation and is set as 60
DEG C, certainly, the present invention is not limited to above-mentioned preset temperatures, other temperature needed due to safety concerns are also that can be applicable in
's.
