SST type Graphite plate column
【Structure and characteristics】
Application of sieve-plate column is one of the first one of the towers. Chemical production in recent years has developed into a major one of mass transfer equipment. Sieve Tray Tower have intensive drilling small holes, so that gas through the sieve in the medium when the liquid drum tower on the board to carry out mass transfer into the process of the bubble.
Graphite plate column with simple structure, convenience, cost less than the bubble-cap tower and valve tower, and the handling capacity and efficiency were higher than the bubble plate towers, etc.. However, because of its flexible production of small, not suitable for low load conditions, as well as gas-liquid sieve blockage Xiao Yi shortcomings, with the result that the application of graphite plate column system rarely. Only in some high temperature and strong corrosion resistance is still useful occasions.
