Welded plate vapour condenser for use in chemistry has vertical plate assembly inside condensing tower calender to give easier access for cleaning

摘要

The vapour condenser has welded plates (2, 3) with collectors (5, 6) on one face positioned vertically inside the calender (1) of a decantation condensing tower, giving free access to their upper and lower ends. The condenser is surrounded by a series of plates (7, 10, 11a, 11b, 12a, 12b), some of which have slightly inclined surfaces to prevent any retention of condensed liquid. The lower part of the calender has a chicane with a vertical section (10b) lying parallel to the plates, leaving a gap for the passage of condensed fluid. When changing from one product to another the calender is cleaned with jets of a cleaning liquid.
