Shell and tube type heat exchanger

摘要

The temperature distribution in a shell and tube type heat exchanger (1) having an expansion joint (7) is uniformized by improving the circulation efficiency of fluid in the shell side. The uniformization is attained by the heat exchanger (1) having an invasion-preventing plate (9) against the fluid in the shell side attached to the expansion joint (7) installed around the periphery of the shell, and a method of catalytic gas phase oxidation reaction that uses the heat exchanger (1).
