からの熱交換流体の漏洩を低減する必要がある。Next, an apparatus for causing the intermediate duct 17 and the intermediate fan box 18 to follow the thermal deformation of the rotors 12, 14 will be described. The dividing portion 16 is connected to the high temperature flow passages 8 and 8 ′ through which the high temperature fluid 1 passes and the low temperature flow passages 9 and 9 ′ through which the low temperature fluid 2 passes, which are partitioned by the intermediate fan box 18 as described above. The communicating side has a small gap between the upper and lower ends of the intermediate fan box 18 and the outer peripheral surface of the rotary shaft 5 to reduce the leakage of the heat exchange fluid from this part and prevent the mixing. Both ends of an intermediate duct 17 that surrounds the outer periphery of 16 and the heat storage bodies 13 and 15 (rotors 12, 1
Since a gap is also formed between the end surface of 4), it is necessary to reduce the leakage of the heat exchange fluid from this gap.

When a difference in thermal expansion and contraction occurs between the rotating body made of and the fixed member made of the intermediate fan-shaped box 18 and the intermediate duct 17, it fluctuates, and the leakage of the heat exchange fluid from the gap increases, and
The sliding resistance between the rotating body and the fixed member may increase. In particular, this thermal expansion / contraction difference forms a counter flow of the high temperature fluid 1 and the low temperature fluid 2 in the duct 3, so that the inlet side of the high temperature fluid 1 and the outlet side of the low temperature fluid 2 are provided. The high temperature side on the heat storage body 13 (rotor 12) side is significantly different from the low temperature side on which the outlet side of the high temperature fluid 1 and the inlet side of the low temperature fluid 2 are provided, and a large gap may occur in the axial direction. .

Even if the heat storage body is divided into a plurality of pieces in the axial direction, the leak of the heat exchange fluid can be suppressed to a minimum. Further, since the cleaning device can be installed in the divided portion where the heat storage body is divided, the heat storage body as a whole becomes longer in the axial direction, and even if the entire length of the passage of the heat exchange fluid in the heat storage body becomes longer, Even with the cleaning device, a significantly improved cleaning effect can be obtained, the fluid passage in the heat storage body is less likely to be clogged, stable operation can be performed for a long time, and the passage resistance is increased due to contamination of the fluid passage. Or, it is possible to prevent the efficiency of the plant from being lowered due to the reduction of the heat transfer efficiency.

A rotary regenerative heat exchanger that exchanges heat by passing high-temperature and low-temperature heat exchange fluids through a heat storage body housed in a rotating rotor, wherein a plurality of heat exchange fluids flow in the heat exchange fluid flow direction. The heat storage body divided into two parts, and an intermediate fan box fixed to an intermediate duct installed in the divided part of the heat storage body to divide the divided part into two in the axial direction, the heat storage body and the intermediate fan shape. A deformation follow-up mechanism that is interposed between a box and follows the axial deformation of the heat storage body to hold the relative position of the intermediate duct and the intermediate fan-shaped box, and the heat storage body constant, and the intermediate A rotary regeneration heat exchanger, which is installed in a duct or the intermediate fan-shaped box and is provided with the heat storage body and a cleaning device for cleaning.
