Description

Technical Field

[0001] This utility model relates to the field of aviation kerosene purification technology, and in particular to an aviation kerosene purification device. Background Technology

[0002] As the core fuel for aircraft engines, the purity of aviation kerosene directly determines the engine's operational safety and service life. During production, storage, and transportation, aviation kerosene is easily contaminated with water, mechanical impurities (such as metal shavings and dust), and gum deposits. Water can cause the fuel system to freeze and metal parts to corrode, mechanical impurities may clog engine fuel nozzles, and gum deposits can accumulate in fuel lines to form carbon deposits. These problems can all lead to engine malfunctions and, in severe cases, even endanger flight safety.

[0003] Existing aviation kerosene purification equipment has many technical shortcomings: most equipment uses only a single filtration structure, which can only remove mechanical impurities and cannot effectively separate moisture and colloids, resulting in a limited purification effect; the filter components are mostly fixed installations, requiring a long downtime for disassembly, cleaning, or replacement, affecting fuel supply efficiency; and the lack of real-time monitoring functions makes it impossible to promptly grasp the purity indicators of the purified kerosene, making it difficult to ensure the stability of purification quality; therefore, we propose an aviation kerosene purification device. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An aviation kerosene purification device includes a purification tank. An oil inlet pipe is fixedly installed on one side of the top of the purification tank, and an oil outlet pipe is fixedly installed on one side of the bottom of the purification tank. A primary filter assembly, a dehydration assembly, and a secondary filter assembly are detachably installed on the inner side of the purification tank from top to bottom. A sampling tube is fixedly installed on the outer wall of the purification tank. One end of the sampling tube extends into the inner side of the purification tank and is located below the secondary filter assembly. A purity detector is fixedly installed on the pipeline of the sampling tube. An exhaust valve is fixedly installed on the top of the purification tank, and a drain valve is fixedly installed on the bottom of the purification tank.

[0011] Preferably, the surface of the control panel is equipped with a display screen and an alarm indicator light. The display screen is used to display the purity data detected by the purity detector and the flow data detected by the flow sensor. When the purity detector detects that the kerosene purity is lower than a preset threshold, the alarm indicator light will automatically light up.

[0012] Preferably, an insulation layer is fixedly installed on the outer wall of the purification tank, the insulation layer is made of aluminum silicate cotton, and support legs are fixedly installed at the four corners of the bottom of the purification tank.
