Abstract

The invention provides a concentration system of ammonium perchlorate. The concentration system comprises an evaporative concentration tank, a steam discharging opening of the evaporative concentration tank is connected with a steam inlet of a steam condensation tank through a pipeline, the steam condensation tank communicates with a concentrated liquid recovery tank, the concentrated liquid recovery tank communicates with a vacuum pump, an evaporative concentration tank motor is arranged on the upper part of the evaporative concentration tank and used for driving a first stirring shaft in theevaporative concentration tank, stirring blades are arranged on the first stirring shaft, the stirring blades are arranged in a hollow mode and provided with rod cavities, electric heating wires arelaid in the rod cavities and connected with an external power source, a foam breaker is mounted on the upper part of the first stirring shaft, and the top of the evaporative concentration tank communicates with an outside-tank foam breaker. According to the concentration system, an ammonium perchlorate solution is properly concentrated and then is crystallized and dried, the product quality and production safety are high, and meanwhile, energy consumption is also lowered.

Description

technical field [0001] The invention relates to the technical field of ammonium perchlorate production, in particular to a concentration system for ammonium perchlorate. Background technique [0002] Ammonium perchlorate is one of the most commonly used oxidizers in solid propellants. It is a white crystal with deliquescence. It will explode when mixed with reducing agents, organic substances, combustible substances such as sulfur, phosphorus or metal powder. Contact with strong acid may cause fire and explosion hazard. For the system of explosives, fireworks, and used as analytical reagents. Therefore, in the production process of sodium perchlorate, safety protection is particularly important. In addition, in the production process of ammonium perchlorate, evaporation concentration, crystallization, drying and other processes are required, and a large amount of heat energy is generated during the reaction process, resulting in waste of resources.
