Abstract

The invention provides a method for flow type ultrasonic processing of intercrystalline acid of a single-compound explosive, and the method comprises the following steps: mixing an acid-containing single-compound explosive crude product with water to form a mixed material; controlling the temperature in a washer to be kept at 25-45 DEG C; enabling the mixed material to enter from the lower end ofthe washer and flow out from the upper end, circulating for a certain time and then performing ultrasonic processing; in the ultrasonic process, controlling the temperature in the washer not to exceed50 DEG C, circularly washing for a certain time, and stopping ultrasonic processing when the pH value in the washer is stable; and filtering and leaching the washed single-compound explosive product,and drying to obtain the single-compound explosive product meeting the acidity requirement. According to the method, washing water is recycled, energy consumption is low, efficiency is high, mass production is easy to achieve, the energy utilization rate of the ultrasonic effect can be increased through circular flowing of the washing water, meanwhile, water consumption is further reduced, and large-scale application of the method can be achieved through series connection of multiple ultrasonic washers.

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...
