In a general heat exchanger, sill plates are usually arranged at appropriate intervals inside the body of the heat exchanger.
With such a diagonal cutting board, the fluid on the shell side is made to flow in a direction substantially perpendicular to the heat exchanger tube group. The fluid on the body side is generally gas or liquid, and by arranging such a diagonal plate,
This serves as a support or guide for the heat transfer tube group to achieve the purpose of improving heat transfer efficiency.

る。 The fluidized bed heat exchanger main body 1 has a fluidized bed 2 in the center of the body, and a group of heat exchanger tubes 3 are housed in the longitudinal direction. The heating fluid enters the body 1 through the lower inlet 6, passes through the fluidized bed 2, and flows out through the upper outlet 7 of the body 1. The barrel wall of the main body 1 is provided with a fluidizing medium inlet 8 and a fluidizing medium outlet 9.

一体に支持されている。 Each heat transfer tube 3 is connected to a heated fluid inlet 4 and a heated fluid outlet 5, respectively (see FIG. 2). The group of heat exchanger tubes 3 is supported by the body wall of the main body 1 at the inlet and outlet portions, and by a support member 12 as shown in FIGS. 1 and 3 at the intermediate upper bend portion. Further, the group of heat exchanger tubes 3 is integrally supported by heat exchanger tube supports 10 and 11 in the vicinity of the upper and lower ends and in the middle part in order to prevent the heat exchanger tubes from swinging.

い得るが、その他適当な手段を用いて良い。 The detailed structure of the heat exchanger tube supports 10, 11 will be explained with reference to FIGS. 4, 5, and 6. As shown in FIG. 4, each heat exchanger tube 3 has a pair of bands 10a,
Each column is connected in such a way that it is sandwiched between 11a. The group of heat exchanger tubes 3 connected in each row by bands 10a, 11a is then connected to another band 1.
Each column is connected by 0b and 11b. Guides (stoppers) 10c, 11c are attached to the ends of the bands 10a, 11a.
0c and 11c are in contact with the inner surface of the shell of the main body 1 to integrally support the group of heat exchanger tubes 3.
To connect the bands 10a, 10b, 11a, and 11b, for example, the connecting means 13 using bolts may be used, but other suitable means may be used.
かように伝熱管サポート１０，１１を構成する
ならば、バンド１０ａ，１０ｂ，１１ａ，１１ｂ
の厚さは十分に薄くバンドの幅方向は各伝熱管の
管軸に平行であるから、上下方向の媒体流動面積
を小さくする惧れは、実質的にない。 If the heat exchanger tube supports 10, 11 are configured in this way, bands 10a, 10b, 11a, 11b
Since the thickness of the band is sufficiently thin and the width direction of the band is parallel to the tube axis of each heat transfer tube, there is virtually no risk of reducing the medium flow area in the vertical direction.

１０ａ，１０ｂの幅は50mm以下にするのが好まし
い。 It is preferable that the widths of the bands 10a, 10b of the heat exchanger tube support 10 provided near the middle and lower ends be as small as possible so as not to impede the movement of the medium in the horizontal direction (see FIG. 5). The floor height is 1
In a fluidized bed 2 having a diameter of m or more, the width of the bands 10a, 10b is preferably 50 mm or less.

である。この目的のためには、バンド１１ａ，１
１ｂの幅は通常100mm以上にすることが好ましい。 As shown in FIG. 6, it is preferable that the widths of the bands 11a and 11b of the heat exchanger tube support 11 provided near the upper end are large. The reason is,
In the upper surface layer of the fluidized bed 2, the medium moves more easily in the horizontal direction than in the middle layer, so that the medium can easily horizontally bypass from the fluidized medium inlet 8 to the fluidized medium outlet 9. But band 11
This is because by increasing the widths of a and 11b, it is possible to reduce the amount of medium bypassed horizontally. For this purpose, bands 11a, 1
It is preferable that the width of 1b is usually 100 mm or more.

１３を用いるときには、かような要請にも安易に
応え得る。 Since the heat exchanger tube supports 10 and 11 of the present invention are usually heated to high temperatures, they are preferably made of heat-resistant steel. Furthermore, since the heat exchanger tube supports 10 and 11 are worn out by the fluidized medium under high temperature conditions, they may need to be replaced after many years of use. For maintenance of such heat exchanger tube supports, it is preferable that the heat exchanger tube supports 10 and 11 be disassembled and removable from the heat exchanger tubes 3. When using the connection means 13 by bolt compression as described above, such a request can be easily met.
本考案は以上説明したような構成であるから、
流動媒体の運動を阻害することなく伝熱管群を有
効に支持し得て、伝熱管の振動や横振れや曲がり
により伝熱管に無理な応力が生ずることを阻止で
きて、流動層熱交換器を安全に運転できる。
Since the present invention has the configuration as explained above,
It is possible to effectively support a group of heat exchanger tubes without inhibiting the movement of the fluidized medium, and it is possible to prevent excessive stress from being generated in the heat exchanger tubes due to vibration, lateral vibration, or bending of the heat exchanger tubes, making it possible to use a fluidized bed heat exchanger. I can drive safely.

できる。 Further, according to a preferred embodiment of the present invention, by increasing the width of the band of the heat transfer tube support provided near the upper end, the medium moves in the horizontal direction in the upper surface layer of the fluidized bed. The heat exchanger tube support provided near the upper end also serves as a rectifying buttful that guides the fluid in the vertical direction, allowing the media with tar to adhere to it to flow smoothly. In addition to discharging the heat exchanger, temperature differences between the upper and lower sides of the heat exchanger tubes are prevented, and the fluidized bed heat exchanger can be operated more stably.
