Device for producing silane by using partition plate tower

The utility model relates to a device for producing silane by utilizing a partition plate tower. The device comprises a rectifying tower I, a rectifying tower II, a rectifying tower III and a rectifying tower IV which are partition plate towers. According to the utility model, the number of the rectifying towers is reduced, the cost in the construction period is reduced, and some energy consumption and maintenance cost in the operation period can also be reduced. The separation plate tower is adopted, light component removal, heavy component removal and other operations are achieved in the same tower, meanwhile, by arranging the backflow pipeline, part of materials are returned to the previous procedure and participate in the reaction again, and the conversion rate of intermediate products is increased. 本实用新型涉及一种利用隔板塔进行硅烷生产的装置，包括形式为隔板塔的精馏塔一、精馏塔二、精馏塔三、精馏塔四。本实用新型减少了精馏塔的数量，其减少建设时期的费用，也能减少运行期的一些能源消耗及维护保养的费用。采用隔板塔的形式，在同一座塔内实现脱轻脱重等操作，同时通过设置回流管线，将部分物料返回前一道工序，重新参与反应，提高了中间产物的转化率。
