VERTICAL MULTI-TUBULAR HEAT EXCHANGER AND DISTILLATION TOWER SYSTEM

摘要

A vertical multi-tubular heat exchanger (1) for exchanging heat by leading process fluid containing lase-of-polymerization into heat exchanger tubes, comprising a shell body (2) extending in vertical direction, an upper tube plate (8) and a lower tube plate (10) installed at the upper part (4) and the lower part (6) of the shell body (2), and the plurality of heat exchanger tubes (28) fixed to these upper tube plate (8) and the lower tube plate (10) at both end part peripheral parts (26) thereof, wherein the upper surface (34) of the upper tube plate (8) is formed aslant, and at least one of the heat exchanger tubes (28) is disposed near the lowest position of the upper surface (34) of the upper tube plate (8).
