Title:
HEAT EXCHANGER AND EXHAUST GAS TREATMENT DEVICE USING SAID HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2015/182094
Kind Code:
A1
Abstract:
Provided is a heat exchanger the interior of which can easily be cleaned and maintained, and with which sufficient heat transfer area can be secured. Also provided is an exhaust gas treatment device using this heat exchanger. This heat exchanger (10) is equipped with heat transfer plates (22) which partition the interior space in a double-pipe structured main body casing (16) into a heat-receiving fluid flow path (18) and a heat-radiating fluid flow path (20), which are formed so as to be contiguous in the axial direction of the main body casing, and so as to have a helical shape across the entirety of the main body casing in the axial direction. A heat-receiving fluid outlet (18b) and a heat-radiating fluid inlet (20a) are provided in the upper end of the main body casing (16), and a head box (24) that defines a space connecting the heat-receiving fluid outlet (18b) and the heat-radiating fluid inlet (20a) is attached to the upper end of the main body casing (16). In addition, on the upper end surface of the main body casing (16) there is mounted a guide member (26), which links the heat-receiving fluid outlet (18b) and the heat-radiating fluid inlet (20a) by means of slanted surfaces (26b, 26c) having a shared apex part (26a), and which guides fluid supplied to the apex part (26a) toward the heat-receiving fluid outlet (18b) and the heat-radiating fluid inlet (20a).
