【摘要】：納米碳酸鈣是一種重要的無機化工產(chǎn)品,從上世紀80年代開始,納米碳酸鈣在我國已經(jīng)實現(xiàn)了產(chǎn)業(yè)化,不同的炭化方法應運而生,規(guī)模越來越大,生產(chǎn)的持續(xù)增長,應用領域不斷擴大。隨著我國化工工業(yè)的發(fā)展,對于納米碳酸鈣晶型、品種、改性工藝等提出了更高的要求。因此,與之配套的納米碳酸鈣制備裝置性能的提高、生產(chǎn)率和產(chǎn)品精細化生產(chǎn)的能力提高,便是擺在我們面前亟待解決的問題。 對于化工設備領域,裝置的設計往往依附于其制備方法體系。由于其行業(yè)的特殊性,化工行業(yè)設備投資大、規(guī)模大、使用時間長,使得一種制備方法在工業(yè)化以后鮮有設備上的改進。而由于投資規(guī)模的龐大,新的技術工藝又無法快速普及,這就為設備的改進設計——用少量的投資帶來大的改進——提供了很大的空間。 本文將目前產(chǎn)品設計中流行的設計方法：QFD設計理論和TRIZ理論結(jié)合,首次應用于化工機械的納米碳酸鈣設備改進設計中,對納米碳酸鈣制備設備進行了改進設計,解決了噴霧法制備納米碳酸鈣設備普遍存在的噴嘴堵塞問題,以及納米碳酸鈣反應溫度等沖突,具有創(chuàng)新性和進步意義,同時也為化工機械領域的設備改進設計提供了一條新思路。
[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.
