Description

Technical Field

[0002] Ammonium perchlorate is a white crystalline powder that is hygroscopic and readily soluble in water. It is a strong oxidizing agent and may explode when mixed with reducing agents, organic matter, or metal powders. Its main uses include being a key oxidizing agent for solid rocket propellants (widely used in spacecraft and missiles), as well as in the manufacture of explosives, pyrotechnics, and analytical reagents. When heated, this compound decomposes, releasing gases such as nitrogen, chlorine, oxygen, and water vapor. It must be stored in a cool, well-ventilated environment and protected from high temperatures, impacts, and contact with strong acids.

[0003] In the crystallization and purification process of ammonium perchlorate, purification equipment is required. The crude product is dissolved in hot water and concentrated to near saturation, and then slowly cooled to below 0°C to promote the preferential precipitation of ammonium perchlorate. However, the existing ammonium perchlorate purification equipment does not have a good waste heat circulation function when heating the crude product, resulting in higher energy consumption during heating, which is not conducive to energy conservation and environmental protection. Therefore, a low-energy consumption purification device for ammonium perchlorate is needed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-energy-consumption purification device for ammonium perchlorate, comprising a device shell and a waste heat circulation mechanism. The waste heat circulation mechanism includes a device base plate, a heating base, a condenser, a coil, a first outlet pipe, and a second outlet pipe. The device base plate is fixedly connected to the bottom of the device shell, the heating base is fixedly connected to the bottom of the device base plate, the condenser is fixedly connected to the inside of the device shell, and the bottom of the condenser is fixedly connected to the device base plate. The coil is fixedly connected to the outer surface of the condenser. There are multiple first outlet pipes, all of which are fixedly connected to the surface of the condenser, and each first outlet pipe is fixedly connected to the coil. There are also multiple second outlet pipes, all of which are fixedly connected to the surface of the condenser, and each second outlet pipe is fixedly connected to the coil. The first outlet pipes are connected to the second outlet pipes through the coils, and the second outlet pipes extend to the outside of the device shell.

[0012] 1. This low-energy-consumption ammonium perchlorate purification device utilizes a waste heat circulation mechanism to reheat the surface of the condenser with water vapor generated during the heating process. This reuse of waste heat generated during crystallization significantly reduces overall energy consumption, carbon emissions, and energy costs during production.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Please see Figure 1-4This utility model provides a technical solution: a low-energy-consumption purification device for ammonium perchlorate, including a device shell 1 and a waste heat circulation mechanism. The waste heat circulation mechanism includes a device base plate 2, a heating base 3, a condenser 16, a coil 18, a first outlet pipe 19, and a second outlet pipe 20. The device base plate 2 is fixedly connected to the bottom of the device shell 1, the heating base 3 is fixedly connected to the bottom of the device base plate 2, the condenser 16 is fixedly connected to the inside of the device shell 1, the bottom of the condenser 16 is fixedly connected to the device base plate 2, the coil 18 is fixedly connected to the outer surface of the condenser 16, there are multiple first outlet pipes 19, all of which are fixedly connected to the surface of the condenser 16, and each first outlet pipe 19 is fixedly connected to the coil 18. There are multiple second outlet pipes 20, all of which are fixedly connected to the surface of the condenser 16, and each second outlet pipe 20 is fixedly connected to the coil 18. The first outlet pipe 19 is connected to the second outlet pipe 20 through the coil 18, and the second outlet pipe 20 extends to the outside of the device shell 1.

[0024] Furthermore, a liquid inlet 12 is fixedly connected to the top of the condenser 16, a condenser tube 13 is fixedly connected inside the condenser 16, multiple fins 14 are fixedly connected to the surface of the condenser tube 13, the top of the condenser tube 13 is fixedly connected to the liquid inlet 12, the bottom of the condenser tube 13 extends to the outside of the condenser 16 and the outer shell 1 of the device, a discharge pipe 15 is fixedly connected to the bottom of the condenser 16, a support rod 4 is fixedly connected to the bottom of the heating base 3, a fixed base 5 is fixedly connected to the bottom of the support rod 4, a water tank 6 is fixedly connected to the top of the fixed base 5, a water pump 7 is fixedly connected to the top of the water tank 6, a first water pipe 8 is fixedly connected between the water tank 6 and the water pump 7, a second water pipe 9 is fixedly connected to the surface of the water pump 7, an annular pipe 10 is fixedly connected to the top of the condenser 16, the second water pipe 9 is fixedly connected to the annular pipe 10, a feeding pipe 17 is fixedly connected to the top of the condenser 16, and multiple nozzles 11 are fixedly connected to the bottom of the annular pipe 10.

[0026] Furthermore, by setting up a waste heat circulation mechanism, the water vapor generated during the heating process can be used to reheat the surface of the condenser, thus reusing the waste heat generated during crystallization. This significantly reduces overall energy consumption, carbon emissions and energy costs during production, while avoiding environmental thermal pollution caused by the direct emission of high-temperature waste heat. It also improves system thermal efficiency, alleviates the load on the cooling system, and extends equipment lifespan, achieving the dual goals of energy conservation, consumption reduction, and clean production. This solves the problem that existing ammonium perchlorate purification equipment lacks a good waste heat circulation function when heating crude products, resulting in higher energy consumption during heating, which is detrimental to energy conservation and environmental protection.
