[0002] In cement plant production, considering the kiln ignition temperature rise and the use of diesel as fuel in emergency situations, a 500m 3 Open-air diesel storage tanks. In an open-air environment, the surface and internal temperatures of ground oil tanks rise rapidly due to exposure to sunlight. The higher the temperature, the faster the flammable liquid evaporates, the greater the vapor concentration on the liquid surface, the greater the possibility of forming an explosive mixed gas with the air, and the greater the risk of fire and explosion. At the same time, most of the heat is concentrated on the surface of the oil interface, which leads to accelerated volatilization and consumption of oil products. However, most of the existing oil tanks adopt the method of regularly spraying water on the top of the tank to achieve cooling. The water will quickly flow along the surface of the tank body, and can only reduce the heat on the surface of the tank body for a short time, and will also cause a waste of water resources. For this reason, an automatic control water spray cooling device for open-air oil tanks is proposed. Utility Model Content

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1-3 As shown, an automatic controlled water spray cooling device for an open-air oil tank comprises a tank body 1 and a mounting frame 2, a water supply pipe 3 is mounted on the mounting frame 2, the upper end of the water supply pipe 3 extends to the top of the tank body 1 and is connected to four shunt pipes 4, each of the shunt pipes 4 is mounted with a water mist nozzle 5 at one end away from the water supply pipe 3, a solenoid valve 6 is connected to the water supply pipe 3, and a temperature sensor 8 is mounted on the top of the tank body 1 for monitoring the temperature inside the tank body 1 so as to control the opening and closing of the solenoid valve 6.

[0018] In this embodiment, the top of the tank body 1 is provided with a first annular water storage enclosure 9, a second water storage enclosure 10 and a third water storage enclosure 11 in sequence from top to bottom. The first water storage enclosure 9 and the second water storage enclosure 10 are provided with a plurality of water flow holes in a circular array, and the third water storage enclosure 11 is provided with a plurality of drainage holes 12 in a circular array.

[0019] In this embodiment, each of the drainage holes 12 is slidably connected with a water blocking block 13, and the top of each of the water blocking blocks 13 is connected with a floating block 14. Each of the water blocking blocks 13 is provided with a drainage groove 15, and the lower end groove of each drainage groove 15 faces the side of the tank body 1. The water in the third water storage enclosure 11 will flow in from the upper mouth of the drainage groove 15 and flow out from the lower mouth of the drainage groove 15 in a direction toward the tank body 1. The water flows down along the outer wall of the oil tank, further taking away the heat of the tank body 1.

[0020] In this embodiment, a filter 7 is installed on the water supply pipe 3 to filter impurities in the water of the water supply pipe 3 to prevent the impurities from clogging the water mist nozzle 5.

[0021] Working process and principle:

[0022] When in use, the temperature sensor 8 on the top of the tank body 1 measures the real-time temperature in the oil tank. When the temperature of the temperature sensor 8 reaches the set upper limit, the solenoid valve 6 is controlled to open, and the water supply is filtered by the filter 7 and then sprayed from the water mist nozzle 5 through the four shunt pipes 4, and evenly sprayed on the top of the tank body 1. After spraying, the water flows on the top of the tank to cool down the top of the tank body 1. When the temperature monitoring temperature of the temperature sensor 8 reaches the set lower limit, the solenoid valve 6 is controlled to close and stop spraying water. However, at this time, the water on the top of the tank does not flow away completely, but gathers in the first water storage enclosure 9, the second water storage enclosure 10 and the third water storage enclosure 1 respectively. 1, the accumulated water in the first water storage enclosure 9 and the second water storage enclosure 10 further absorbs heat and cools down, while flowing from the water flow hole to the next water storage enclosure, thereby increasing the residence time of water on the top of the tank body and improving the cooling effect, and the water in the third water storage enclosure 11 will flow downward through the drainage groove 15 on the water blocking block 13. As the water level in the third water storage enclosure 11 drops, the water blocking block 13 will also drop under the action of buoyancy, so that the drainage groove 15 is closed and no water is discharged, so that a layer of water is left on the top of the tank body 1, which prevents the temperature of the tank body 1 from rising rapidly after the water is sprayed for cooling, thereby achieving the purpose of saving water.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
