摘要
研究了无筛板流化床的数学模型，在试验中采用了作者提出的新的流化指数表达式，作为流化质量的判别标准．用内径０．７５ｍ，由透明有机玻璃制成的无筛板流化床作为模拟放大装置，并把计算机及差压变送器等仪器与无筛板流化床相连接以实行联机操作并处理数据．根据数学模型研究结果，设计了一台内径１．２ｍ工业用无筛板沸腾氯化炉，用于氯化品位约８５％ＴｉＯ２，含６．７％ＭｇＯ与ＣａＯ杂质的高钛渣制取ＴｉＣｌ４，氯化炉连续运转５５天。
The mathematical modelling of
fluidized\|bed without the perforated\|plate has been studied.The fluidization expression given
by the has been used in tests and as a criteria of fluidization quality. A 0\^75m\|ID clear
plexiglass fluidized\|bed without the perforated\|plate was used for a amplificative simulator.
The computer and differential pressure transducer etc. were connected to the fluidized\|bed
without the perforated\|plate for processing data in a real\|time on\|line operation. Based on the
mathematical modelling, a 1\^2m\|ID commercial fluidized\|bed without the perforated\|plate
chlorinator has been designed for chlorinating titanium\|rich slag containing approximately 85%
TiO\-2, 6\^7% MgO and CaO impurites to produce TiCl\-4. The chlorinator has run continuously
for 55 days with a good fluidization.
