The invention relates to a device for adding nitrogen in aviation kerosene and a cleaning method, wherein a nitrogen mixing device is arranged on an input pipeline for inputting aviation kerosene into a workpiece to be cleaned. The device comprises a nitrogen introducing hole for introducing nitrogen, and a nitrogen adding joint communicated with the nitrogen introducing hole and inserted into the input pipeline, and nitrogen is uniformly mixed into the aviation kerosene till the aviation kerosene reaches a saturated state. The cleaning method comprises the steps of: uniformly blending the nitrogen into supercharged aviation kerosene, wherein the mixing quantity of the nitrogen ensures that the supercharged aviation kerosene is saturated; after the aviation kerosene enters the workpiece to be cleaned, stripping polluting particles from the wall of the inner cavity when the aviation kerosene overturns because the nitrogen in the aviation kerosene is released due to sudden pressure drop; and carrying the stripped polluting particles out of the workpiece by the overturning aviation kerosene, thus finishing the cleaning. The device has better cleaning effect for the workpiece with complex internal pipelines or connectors and large internal capacity; and according to the invention, the isolation of the aviation kerosene from air is reduced, and the safety of the aviation kerosene during use is effectively enhanced.
Description
technical field [0001] The invention relates to a cleaning device and a cleaning method using aviation kerosene as a medium, in particular to a device and a cleaning method for adding nitrogen into aviation kerosene. Background technique [0002] At present, there are several methods for cleaning various containers and finished workpieces: ultrasonic cleaning, spray cleaning, mechanical automatic scrubbing, bubbling flushing, etc., and different cleaning methods can be selected according to the parts to be cleaned and the cleaning medium. The cleaning method is carried out. [0003] 1. Ultrasonic cleaning: Generally, non-volatile and flammable cleaning liquids such as water and washing liquid are used as the medium in the ultrasonic cleaning machine, and the cavitation effect of ultrasonic waves in the cleaning liquid is mainly used to achieve the purpose of cleaning. Therefore, it is difficult for conventional cleaning Products that meet the cleanliness requirements, espec...
