【摘要】：纳米碳酸钙是一种重要的无机化工产品,从上世纪80年代开始,纳米碳酸钙在我国已经实现了产业化,不同的炭化方法应运而生,规模越来越大,生产的持续增长,应用领域不断扩大。随着我国化工工业的发展,对于纳米碳酸钙晶型、品种、改性工艺等提出了更高的要求。因此,与之配套的纳米碳酸钙制备装置性能的提高、生产率和产品精细化生产的能力提高,便是摆在我们面前亟待解决的问题。对于化工设备领域,装置的设计往往依附于其制备方法体系。由于其行业的特殊性,化工行业设备投资大、规模大、使用时间长,使得一种制备方法在工业化以后鲜有设备上的改进。而由于投资规模的庞大,新的技术工艺又无法快速普及,这就为设备的改进设计——用少量的投资带来大的改进——提供了很大的空间。本文将目前产品设计中流行的设计方法：QFD设计理论和TRIZ理论结合,首次应用于化工机械的纳米碳酸钙设备改进设计中,对纳米碳酸钙制备设备进行了改进设计,解决了喷雾法制备纳米碳酸钙设备普遍存在的喷嘴堵塞问题,以及纳米碳酸钙反应温度等冲突,具有创新性和进步意义,同时也为化工机械领域的设备改进设计提供了一条新思路。
[Abstract]:Nano-calcium carbonate is an important inorganic chemical product. Since the 1980s, nano-calcium carbonate has been industrialized in China. Different carbonization methods have emerged as the times require. With the development of chemical industry in China, higher requirements have been put forward for nano-CaCO3 crystal type, variety, modification process, etc. Therefore, the performance of the corresponding nano-CaCO3 preparation unit has been improved. The improvement of productivity and the ability of fine production is the problem that needs to be solved urgently in front of us. For the chemical equipment field, the plant design often depends on its preparation method system. Because of its industry particularity, the chemical industry equipment investment is large, the scale is large, the use time is long, It makes a preparation method rarely improve on equipment after industrialization, and because of the scale of investment, the new technology can not be popularized quickly. This provides a lot of room for improving the design of the equipment-big improvements with a small amount of investment. In this paper, the popular design method in product design is combined with the TRIZ theory, and it is applied to the improvement design of nano-calcium carbonate equipment in chemical machinery for the first time, and the preparation equipment of nano-calcium carbonate is improved. The problems of nozzle blockage and reaction temperature of nano-CaCO _ 3 prepared by spray method are solved, which is of innovative and progressive significance. At the same time, it also provides a new idea for the equipment improvement design in the field of chemical machinery.
