Description
Technical Field
The invention relates to the field of fire early warning of an oil storage tank, in particular to a fire boil-over and splash early warning device of the oil storage tank.
Background
Crude oil is crude oil produced underground. Crude oil is a mixture of hydrocarbons, the main component being hydrocarbons. Crude oil is highly viscous and contains some moisture to varying degrees. The crude oil contains free water and emulsified water, in the case of a crude oil fire, the water in the crude oil is heated and vaporized by heat waves to become water vapor, the vapor bubbles are surrounded by an oil film to form a large amount of oil foam, so that the volume is expanded violently, and when the vapor bubbles exceed the capacity of a storage tank, the vapor bubbles overflow the outside of the tank like a porridge boiling overflow pot, so that boiling overflow is caused. With the continuous progress of combustion, the temperature of the heat wave gradually rises and continuously moves downwards, when a large amount of water is quickly vaporized into steam when a hot front surface meets a water layer (or a large amount of water), the volume of the water layer is expanded by 1700 times, the steam pressure of the water layer is also quickly increased, when the steam rushes out of the water layer at a high pressure, crude oil on the upper part of the water cushion layer is thrown upwards to the air to form splashing to bring the ignited oil product to the air, and a huge fire column is formed, which is called splashing. The boiling over and the splashing are extremely harmful to the crude oil fire, the boiling over can enable the crude oil to splash for a distance of dozens of meters, and when the large oil tank stores much oil, the overflowing area can reach thousands of square meters, so that the fire can spread in a large area. When the flame of the crude oil is suddenly emptied during splashing, the fire column can reach 70-80 m, and the jet distance of the fire column along the wind direction can reach about 120 m. When the flame rolls down, the flame spreads all around, and easily spreads to an adjacent oil tank, thereby enlarging the disaster situation, and possibly causing the fire extinguishing personnel to be suddenly surrounded by the flame, and causing casualties.
In the prior art, an infrared flame detector and a linear light beam detection mode are generally used for detecting a fire disaster of an oil product storage tank, and although the fire disaster can be found as early as possible, whether boiling overflow and splashing happen or not and the occurrence time of the fire disaster cannot be well predicted, so that the personal safety of fire fighters is threatened.

Referring to the attached figure 1, the sonar probe 11 of the present invention is mainly fixed below the oil surface by a fixed support 23 or fixed at the bottom of the oil storage tank by a fixed cable 32, and the outside is surrounded by a cooling device 12, so that bubbles generated by the evaporation of water in the oil storage tank 21 can be detected when the oil storage tank is in a fire based on the sound wave transmission principle. By adopting a sonar mode to receive information of bubbles generated by liquid in the oil product storage tank 21, the problems that wiring is complex and the wiring is easy to damage in a high-temperature environment during fire disaster and information cannot be effectively transmitted when a wired mode is adopted for information transmission can be avoided;
referring to the attached drawing 1, the cooling device 12 of the invention is surrounded outside the sonar probe, when a fire breaks out in the oil product storage tank 21, the oil temperature around the sonar probe 11 is cooled, and the problem that the sonar probe 11 fails due to high oil temperature when the fire breaks out can be avoided; the cooling device 12 is provided with a temperature sensor which can monitor the oil temperature in real time and start to work for cooling when the oil temperature reaches a preset value;

Specifically, the oil storage tank in case of fire is taken as an example to explain the oil storage tank fire boil-over and splash early warning device based on sonar. The crude oil contains water and the relative density of the water is less than that of the water, so that the water in the crude oil is gradually evaporated and accumulated at the bottom of a crude oil storage tank, once a fire disaster occurs, the temperature of the crude oil is continuously increased, the crude oil starts to burn and generates a heat wave when the temperature reaches the ignition point of the crude oil, the heat wave gradually moves towards the bottom of the crude oil storage tank, the water accumulated at the bottom of the crude oil storage tank is gasified by the heat wave because the temperature of the heat wave is far higher than the boiling point of the water, a large amount of steam floats upwards through the crude oil to the liquid surface, bubbles of oil-in-gas are formed in the upward movement process, the viscosity of the oil is reduced along with the increase of the oil temperature, and the bubbles are generated more violently. Therefore, the volume of the crude oil is inevitably expanded and the crude oil overflows outwards, and meanwhile, part of the crude oil which does not form foams is thrown out of the oil storage tank by the expansion force of steam below the crude oil, so that the crude oil surface is violently boiled, and the boil-over phenomenon is caused.
In this example, two different probe arrangement modes can be adopted according to actual conditions, the sonar probe 11 monitors bubbles generated inside the oil product storage tank 21 when a fire breaks out in real time, and transmits a measurement result to the display device 13; when a fire disaster happens, the oil temperature in the oil storage tank 21 is higher and higher, the viscosity of the oil is reduced, the number and the rising rate of bubbles are increased, the information of the bubbles is detected by the sonar probe 11 and transmitted to the display device 13, the display device 13 receives and reads and analyzes the bubble information, and before the bubbles are generated and the rising rate meets the requirement of triggering boiling overflow splashing, the information is transmitted to the alarm device 14 and controls the alarm device 14 to alarm, and people are reminded to evacuate.
The invention has the following beneficial effects:
(1) the oil storage tank fire spill-over and splash early warning device based on the sonar can detect the generation quantity and the rising rate of bubbles in oil through the sonar probe to judge whether spill-over and splash happen or not when an oil tank fire happens and the fire cannot be effectively extinguished after conventional fire-fighting measures are taken, and transmits information to the warning device before the spill-over and splash happen to trigger the warning device to give an alarm to remind workers to evacuate, so that casualties are reduced.
(2) The invention is provided with the cooling device which can cool the sonar probe surrounded by the cooling device through the circulation of condensate liquid per se, thereby ensuring the normal operation of the sonar probe.
(3) The display device provided by the invention can clearly show the number of bubbles and the rising rate.
