Specific embodiment
Below against attached drawing, by the description of the embodiment, making further details of theory to the specific embodiment of the invention
It is bright, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
As Figure 1-Figure 5, the present invention provides a kind of flammable liquid storage tanks, including upright tank body 1, the tank body 1
It is equipped with oil inlet.The oil inlet includes the oil inlet interface 17 equipped with flange, and the interface end of the oil inlet interface 17 is covered with
Oil inlet strainer 18, the end that the oil inlet interface 17 protrudes into the tank body 1 are equipped with interface tube and connect with the oil pipe for passing through nitrogen sealing
It connects, 17 flanged joint of oil inlet interface has feed cover 19, and the feed cover 19 is equipped with the through-hole of insertion oil inlet pipe.Through-hole can pass through
The capping of threaded connection seals.Oil inlet strainer 18 can filter the solid impurity in injection liquid, guarantee the pure of pot liquid.
Liquidometer 5 is equipped at the top of the tank body 1, the measuring rod 6 of the liquidometer 5 is extend into the tank body 1.Tank body 1
Top is equipped with the liquidometer installing port of flange arrangement, and liquidometer 5 is the connecting rod floating ball lever meter being fixed on flange arrangement, is passed through
Floating ball measurement liquid level on measuring rod 6 is set.Liquidometer 5 is mounted on liquidometer peace by being equipped with the flange of sealing structure
Mouth is filled, measuring rod 6 is extend into always close to 1 bottom position of tank body, for detecting liquid height.
1 upper side of tank body is also communicated with nitrogen pipeline 2, and the nitrogen pipeline 2 is equipped with nitrogen envelope valve 11 and passes through
Pressure reducing valve 15 is connected to the outlet of nitrogen gas tank 16, and ventilating bent-tube 4 is equipped at the top of the tank body 1, is equipped at the ventilating bent-tube 4 unidirectional
Outlet valve 13.1 inside upper part of tank body is equipped with nitrogen holding tank 12, and the nitrogen holding tank 12 is by being equipped with breather valve 14
Opening be connected to the nitrogen sealing in tank body 1, the ventilating bent-tube 4 is communicated to nitrogen holding tank 12, and the breather valve 14 is exhaled
The powerful expiration pressure in the one-way breather valve 13 of air pressure.
Flammable liquid and air exclusion are prevented into spontaneous combustion by being filled with the nitrogen formation nitrogen sealing on top in this way, ensure that liquid
Body will not leak easily volatilization occurs.Nitrogen envelope valve 11 guarantees that air pressure maintains level of security in tank body 1, releases liquid gas
Pressure drop low energy is automatically replenished nitrogen, and after liquid is added, extra nitrogen can enter nitrogen holding tank 12 by breather valve 14, guarantees tank
Body 1 and extraneous normal pressure difference.Due to the powerful expiration pressure in the one-way breather valve 13 of the expiratory pressure of breather valve 14,
There is no concern that ambient atmos enter tank body 1.When temperature increases or liquid is added, nitrogen pressure is increased in tank body 1, and nitrogen is temporary
Depositing pressure in case 12 should be suitable with the expiration pressure of one-way breather valve 13, therefore 1 nitrogen of tank body can be discharged into nitrogen holding tank 12,
It is discharged again through one-way breather valve 13.When mercury dropped or discharge liquid, air pressure reduces in tank body 1, and tank body 1 seals valve from nitrogen first
11 obtain nitrogen.If nitrogen pipeline 2 is because nitrogen cannot be replenished in time in failure or nitrogen deficiency, air pressure drops to centainly in tank body 1
Nitrogen therein can be added to nitrogen sealing by breather valve 14 by level, nitrogen holding tank 12, and the short time does not influence storage tank use,
It sets apart and repairs ventilation.And leakage part, which occurs, for any of breather valve 14 and one-way breather valve 13 will not influence tank body
Internal nitrogen seals effect, more preferable to the fault-tolerance of valve body failure.

Bottom is equipped at least three stabilizer blades 10, equidistant to be circumferentially distributed in 1 bottom peripheral edge of tank body.
Around cooling water pipe 3 is fixed with, the cooling water pipe 3 is arranged below towards the tank 1 upper side of tank body
The spray head of body 1, the cooling water pipe 3 are equipped with the water inlet line being connected with cooling water tank, and the water inlet line is equipped with cooling water
Valve.Temperature inductor is equipped on the outside of the tank body 1 and is connected to the wireless communication device of temperature inductor, and the cooling water valve is
Electric control valve, device is signally attached to safety control module, the security control mould to the temperature inductor by wireless communication
Block is electrically connected with electric control valve.Safety control module can will obtain information compared with safe temperature, when temperature reach a certain height,
Safety control module can allow cooling water valve to be opened through spray head to 1 surrounding of tank body into spraying cooling automatically, both can be reduced liquid and wave
Hair vaporization, and high temperature is avoided to lead to the probability of liquid spontaneous combustion.The structure and nitrogen plugging structure above-mentioned cooperate, which can prevent
Only liquid vaporization is revealed, to the normal barometric pressure in liquid cooling, maintenance tank body 1, substantially increases the safety of flammable liquid storage tank
Property.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, it is or not improved as long as using the improvement for the various unsubstantialities that the method for the present invention conception and technical scheme carry out
Present inventive concept and technical solution are directly applied into other occasions, within that scope of the present invention.
