[0016] (2) As civilian explosives: the direct utilization of discarded propellants, propellants and explosives, such as the yellow explosive TNT, which is taken out from the bomb, purified into pieces, and directly introduced into industrial powder explosives. Some sensitive propellants , propellants and explosives, such as RDX, will be reused after insensitization; the special mixture explosives made, these propellants, propellants and explosives are used for metal processing and other purposes, such as: Explosive compounding of metals, explosive cutting, explosive forming, explosive strengthening and explosive hardening, explosive riveting and welding, explosive stress relief, and explosive powder compaction, etc., the price of this type of explosive is relatively high, but the consumption is small, it is not large An Efficient Way to Dispose of Expired and End-of-Life Propellants, Propellants and Explosives at Scale
[0025] Ammunition, especially the propellant, contains a large amount of lead. At present, the removal methods for lead mainly focus on the following methods: precipitation method, coagulation method, adsorption method, and ion exchange method. method, the effect is good, but there is a shortcoming, the separation process of pyrrhotite and pyrite in natural pyrite is more complicated, and the workload is large, which limits the practical application, but it is rare to apply the above method to propellant Removing lead in fertilizer making

Abstract

The invention specifically relates to a safe disposal and resourceful utilization system for an energetic material and an implementation method for the system, belonging to the technical field of treatment of energetic materials. The system comprises a batching tank, a reaction tank, a material supplementing tank, an overflow recovery tank, a gas recovery tank, a compressor unit, a heating unit, a refrigerating unit, a gas detection device, a gas condensation device, a supersonic generator, a stirring device driven by a motor, a temperature test automatic control device, a pressure testing device, a pH value test automatic control device and an ion concentration detection device. The system is used for treatment of an energetic material to prepare a fertilizer which can be utilized by mankind through hydrolysis and conversion; in the process of preparation of a fertilizer, lead in a lead-containing energetic material is removed to reduce lead content in the fertilizer, so the content of lead absorbed by a crop from soil is reduced, thereby further alleviating harm to a human body caused by lead included in food.

Description

technical field [0001] The invention belongs to the technical field of energetic materials processing, and in particular relates to a system for safe disposal and resource utilization of energetic materials, and also relates to a method for realizing the system. Background technique [0002] The energetic materials used in ammunition mainly include propellants, propellants and explosives.
