Title:

COUNTERCURRENT-TYPE DIRECT-HEATING HEAT EXCHANGER

Document Type and Number:

WIPO Patent Application WO/2017/159837

Kind Code:

A1

Abstract:

Provided is a countercurrent-type direct-heating heat exchanger in which wear of a container due to a heating subject fluid can be inhibited. The countercurrent-type direct-heating heat exchanger (A) is provided with a container (10), a feed pipe (11) which is horizontally provided in the container (10) and which feeds the heating subject fluid (1), a feed port (12) which is provided at an end section of the feed pipe (11) and which opens vertically downwards, and a rectifier (40) connected to the feed port (12). The rectifier (40) is provided with a cylinder body (41) and a guide plate (45) provided in the cylinder body (41). The guide plate (45) is disposed so as to partition the interior of the cylinder body (41) into a channel (46a) on the upstream side of the feed pipe (11) and a channel (46b) on the downstream side of the feed pipe (11). The upper end of the guide plate (45) projects into the feed pipe (11). It is possible to increase the flow rate of the heating subject fluid introduced into the channel (46a) on the upstream side, and suppress the flow rate deviation of the heating subject fluid (1).
