Title:
MULTIPLE TUBE-TYPE HEAT EXCHANGER AND HEAT TRANSFER TUBE CLEANING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2017/126148
Kind Code:
A1
Abstract:
A multiple tube-type heat exchanger has a simple structure which enables heat transfer tubes accommodated within a heat exchanger shell to be efficiently cleaned, enabling the heat exchanger to be operated with high energy efficiency.
A multiple tube-type heat exchanger (25) is provided with a cylindrical heat exchanger shell (36) and a heat transfer tube unit (38) which is mounted in a removable manner within the heat exchanger shell (36). The heat transfer tube unit (38) is provided with: a plurality of heat transfer tubes (50) extending inside the heat exchanger shell (36) in the longitudinal axis direction; a binding member (51 serves also as this binding member) for binding the heat transfer tubes (50); and a plurality of rotary journal sections (51, 52) which are concentric with the center axis (CL) of the heat transfer tube unit (38), are provided at positions located at a distance from each other in the direction of the center axis (CL), and enable the heat transfer tube unit (38) to be supported by predetermined rotation support sections provided outside the heat exchanger shell (36).
