Shell and tube heat exchanger and method for removing volatile substances from a polymer solution |
摘要 |
A shell-and-tube heat exchanger, for removing volatile substances from a polymer solution by degasification, includes a bundle of tubes arranged vertically and parallel to each other in a shell chamber through which a fluid heat-transfer medium flows. The upper end of each tube is fixed in an upper tube sheet and the lower end of each tube is fixed in a lower tube sheet, and the polymer solution flows through the tubes in the direction of gravity. One feature is that a multilayer woven wire fabric is attached to the top of the upper tube sheet. The finest meshed layer of the fabric has a mesh width of 50 mum to 1000 mum. The invention also relates to a method for removing volatile substances from a polymer solution by degasification in a shell-and-tube heat exchanger and use of the shell-and-tube heat exchanger. |
