Abstract: The working principle，the present research and the development of the fluidized bed reactors for organosilicon monomer synthesis were discussed in this paper. In addition，the advantages and disadvantages of existing interior heat transfer structure and gas distributor were presented. On this base，a new type of fluidized bed reactors for organosilicon monomer were discussed，as well as its advanced two level of disk conduction oil distributor and double cone-diversion gas distributor in details. This new type of device，representing a new direction for the fluidized bed reactors，has the following characteristics：low energy consumption，adopting technology for catalyst directly back to bed. Besides，the conducting-heat oil flows once-through in the figure-pipe bundles multiply，and absorbs heat uniformly.

摘要： 介绍了应用于有机硅单体合成中的流化床反应器的工作原理及其技术的进展和国内外现状，分析了现有的流化床反应器内部换热结构及底部气体分布器，并指出了的主要优缺点。在此基础上重点介绍了一种新型有机硅单体流化床反应器以及改进的指管束二级管盘式导热油均布器。该设备的特点是：指管束中的导热油并联直流，取热均匀；能耗低，采用了催化剂直接回床技术，代表了有机硅流化床反应器新的发展方向。
