摘　　要：目前国内生产三氯化铝普遍采用在熔化的铝液面通入氯气的生产工艺,氯气的加入量采用人工调节方式,导致生产效率低下或者氯气过量排放。通过对生产过程的研究,设计了基于STC15单片机的自动氯气调节控制系统,该系统根据熔液的温度调节氯气流量,获得最佳反应温度。通过近一年生产表明,该控制系统大大提高了生产效率,减少了过剩氯气,因此减少了尾部对氯气的处理难度和物质损耗,降低了空气污染。At present, the production process of pumping chlorine into the molten aluminum liquid is widely used in producing aluminum trichloride in our country and the amount of chlorine is manually adjusted, resulting in low production efficiency or excessive elimination of chlorine. By studying the production process, an automatic chlorine regulation and control system is designed based on STC15 single chip microcomputer. It is shown that the control system greatly improves the production efficiency and reduces the surplus chlorine, which reduces the difficulty of chlorine treatment and material loss at the end and the air pollution.
