Embodiment 1

[0040] Embodiment 1 adopts the heat-giving method of the present invention to produce potassium perchlorate

[0041] Heat transfer oil medium conveying material: 304 stainless steel with a thickness of 6 mm is selected as the heat transfer oil conveying material.

[0042] Potassium perchlorate production process roadmap is as follows figure 2 shown. Flow chart of heat transfer oil see figure 1 .

[0043] The heat-conducting oil is heated to 150°C from the heat-conducting oil heating device and then sent to the expansion device. The heat-conducting oil after heat exchange in the expansion device is sent to the potassium chloride solution to be heated or the metathesis material to be heated (a mixture of potassium chloride and sodium perchlorate) After heat transfer, the heat transfer oil returns to the heat transfer oil recovery device (temperature is about 100°C), and is sent to the heat transfer oil heating device for heating. After the heat transfer oil is heated to 150°...

Abstract

The invention relates to a comprehensive utilization method of heat energy in a potassium perchlorate production process, which belongs to the technical field of potassium perchlorate production. The invention aims to solve the technical problem of providing a new heat supplying method for the technical field of potassium perchlorate production, increases energy utilization efficiency and solves environmental pressure caused by the three wastes generated by the coal consumption of a boiler. The invention has the technical schemes of: heating by adopting high-temperature heat conducting oil, in particular to a conduction process that after the heat conducting oil is heated, transmitting heat to materials which need to be heated to cause that the temperature of the heat conducting oil is reduced, and repeatedly heating. The comprehensive utilization method increases energy utilization efficiency and reduces the environmental pressure caused by the three wastes generated by the coal consumption of a boiler, and otherwise, the comprehensive utilization method increases continuous production capacity, is suitable for large-scale production requirements and breaks the tradition that a perchloric acid double-decomposition process is only heated by steam in a long period.

Description

technical field [0001] The invention relates to a comprehensive utilization method in the production process of potassium perchlorate, belonging to the technical field of potassium perchlorate production. Background technique [0002] Potassium perchlorate is mainly used in the production of firecrackers and fireworks. my country is a big producer of traditional firecrackers and fireworks, so the production of potassium perchlorate is relatively large. [0003] The double decomposition process in the production process of potassium perchlorate needs to provide a heat source, and the operating conditions are high and belong to high temperature and high pressure. Although the traditional boiler heating can meet the production needs, the energy utilization efficiency is low, difficult to control and prone to injury accidents. for example: [0004] Zhang Wusong reported [Chlorate Industry Anthology 2007] a potassium perchlorate discharge production process, the potassium chlo...
