Abstract

The present invention proposes a flow-type ultrasonic treatment method for the intercrystalline acid of elemental explosives, which comprises taking the crude acid-containing elemental explosives and mixing them with water to form a mixed material; controlling the temperature in the scrubber to keep at 25-45°C; making the mixed material from washing The lower end of the washer enters, the upper end flows out, and ultrasonic treatment is performed after a certain period of circulation; during the ultrasonic process, the temperature in the washer is controlled not to exceed 50°C, and after a certain period of cycle washing, the ultrasonic treatment is stopped when the pH value in the washer is stable; The explosive product is dried after being filtered and rinsed to obtain a simple explosive product meeting the acidity requirement. In this method, the washing water is recycled, the energy consumption is low, the efficiency is high, and it is easy to realize mass production. The method can improve the energy utilization rate of the ultrasonic action through the circulating flow of the washing water, and also further reduce the consumption of water, and the method can be used Large-scale application is realized by connecting multiple ultrasonic scrubbers in series.

Description

technical field [0001] The invention belongs to the technical field of explosives, and in particular relates to a flow-type ultrasonic treatment method for the intercrystalline acid of simple explosives such as Hessogen, Octogen, Taian and the like. Background technique [0002] In the manufacturing process of elemental explosives, nitric acid and sulfuric acid are often used as oxidants. After nitration, crystallization and other processes, a certain amount of residual acid is usually attached to the crystal surface and between the crystals of elemental explosives, and the treatment of residual acid is the process of elemental explosives manufacturing. a difficult problem. Taking Octogen as an example, the acidity of its crude product is about 9%. The residual acid on the surface of the crystal can be removed by conventional washing, and its acidity is reduced to about 1%. The remaining residual acid is intercrystalline acid. It is difficult to deal with. The current commo...
