One embodiment of the present invention will be described with reference to FIGS. 1 to 4. Reference numeral 20 denotes a side plate of the water chamber 8 to which the heat exchange tube 7 is attached, and is attached to the cover 21. Openings 22 connected to each heat exchange tube 7 are provided at predetermined positions. Reference numeral 23 denotes a flange sleeve having a flange portion 24 formed at one end thereof that abuts around the opening 22 of the side plate 20 via an O-ring 25 or packing or other watertight seal, and whose inner diameter is the same as the end of the heat exchange tube 7. However, the inner diameter near the flange 24 should be smaller than this, so that the heat exchange tube 7 can be watertightly fitted into the flange sleeve 23 via an O-ring 25 or packing or other watertight seal. It is designed to be inserted.

ある。 Further, 26 is a holding plate for pressing the flange 24 of the flanged sleeve 23 against the opening 22 of the side plate 20. For example, the maximum width of the holding plate 26 is
W 1 is the gap between the outer diameters of adjacent heat exchange tubes 7
Although the width W 3 between adjacent heat exchange tubes 7 is smaller than the gap W 4 between the outer diameters of the flanged sleeve 23, it is still wide enough to hold the flanged portion 24; By this pressing plate 26, the adjacent flanges 24 are simultaneously held together by the O-ring 25.
It is pressed against the side plate 20 in a watertight manner through a watertight seal such as, but the vicinity of both ends of the holding body 26 is fixed, and the holding body 26 is made detachable from the side plate 20 with bolts 27.

ユーブ７を容易に取外すことができる。 Therefore, after the end of the heat exchange tube 7 is watertightly inserted into the flanged sleeve 23, the flanged portion 24 is positioned in alignment with the opening 22 of the side plate 20, and the flanged portion 24 is held down by the presser plate 26. After attaching the heat exchange tube 7 by holding it down and fixing the vicinity of both ends in a watertight manner to the side plate 20 with fixing bolts 27, insert the heat exchange tube 7 into the discharge pipe 6 together with the cover 21 as shown in FIGS. 3 and 4. is set. In addition, when removing the heat exchange tube 7, pull up the cover 21 together with the side plate 20 and remove the fixing bolts 27.
The heat exchange tube 7 can be easily removed together with the flanged sleeve 23 by removing the retainer plate 26, shifting the holding plate 26 to the left side in FIG. 2, and pulling it out.

20Kgｆ／cm2でも漏れ量は零であつた。 In this way, in the present invention, the side plate 20 only needs to be processed by simple hole drilling, and the end of the heat exchange tube 7 is fixed to the side plate 20 via the flanged sleeve 23 with the removable holding plate 26. Therefore, even if there is an error between the inner diameter of the heat exchange tube 7 and the center position of the opening 22 of the side plate 20, the sleeve 23 can be positioned easily and the flanged sleeve 23 can be fixed to the side plate 20 in a watertight manner by the holding plate 26. This makes it possible to easily attach and detach any heat exchange tube 7 as needed. Also, when attached, the presser plate 26 presses the flange 24 against the side plate 20 with an even force, and the attachment section The reliability of watertightness has also been greatly improved, and experiments have shown that
Even at 20Kgf/cm 2 , the amount of leakage was zero.
