The iron chains of composition, and the ring section of adjacent suspension ring 205 is mutually perpendicular to interlock, and is conducive to increasing the shifting of adjacent suspension ring 205
Dynamic space.The crossbeam 203 is distributed in the both sides of heat exchanger body, the two ends of each crossbeam 203 placement pillar 204, and is somebody's turn to do
Above-mentioned suspender belt 201 is provided between pillar 204.
In the present embodiment, the suspension ring 205 have the upper and lower suspension ring 2050,2051 positioned at two ends and semicircular in shape, and divide
Do not interlocked with other suspension ring 205, be beneficial to the connection of suspension ring 205 and high temperature resistant heat exchanger and crossbeam 203, i.e. upper lift ring 2050
On the crossbeam 203 of supporter 202, lower lift ring 2051 is connected on the heat exchanger body of high temperature resistant heat exchanger, and
Upper lift ring 2050 is located at the upside of lower lift ring 2051 and high temperature resistant heat exchanger connecting place with the connecting place of crossbeam 203, so that resistance to height
Warm heat exchanger is hung on the rest 200 completely, i.e., in hanging hanging state, so that, when the heat exchanger sheet of high temperature resistant heat exchanger
After body expanded by heating, relatively existing high-temperature heat-exchanging, the present invention can be easy to heat exchanger body to move, and can prevent heat exchanger sheet
Body is conducive to extending the service life of high temperature resistant heat exchanger because cracking phenomenon after inequality of being heated.
Referring again to shown in Fig. 1, the preceding upper end (i.e. the upper end of the first high temperature section 41) of the heat exchanger body has shell-side outlet
43, the rear upper end (i.e. the upper end of the second low-temperature zone 42) of the heat exchanger body has shell side import 53.
First high temperature section 41 is connected with the heat exchanger tube of the second high temperature section 42, but is changed with high-temperature region heat exchanger 40 and low-temperature space
It is not communicated between the pipe of hot device 50, and between first, second high temperature section and the second high temperature section and low-temperature space heat exchanger junction
Side wall on offer be easy to maintenance manhole 102.
Fig. 6 is referred to, shown in 7, the high temperature resistant heat exchanger further includes thermal insulating filling 82, between adjacent heat exchange tubes
Metal platen 83 and gear pipe 84 that is outer positioned at metal platen and being set on heat exchanger tube 90；The thermal insulating filling 82 is located at first
Between high temperature section 41 and tube side imported equipments and parts 10, and back tube sheet 81 and heat exchanger tube 90 in first high temperature section 41
One end be fixedly connected (be such as fixed together by welding manner), so as to sealed against each other between heat exchanger tube and pipe, but heat exchange
The other end of pipe 90 through front tube sheet 80 pore and together with being not fixed to front tube sheet 80, i.e., on described front tube sheet 80
Pore is slightly larger than the nozzle diameter of heat exchanger tube 90, so that heat exchanger tube is mutually shifted in the pore of front tube sheet；To prevent heat exchange
It is mutually communicated between pipe 90 and pipe, above-mentioned thermal insulating filling 82 is filled between heat exchanger tube, and is clamped in front tube sheet 80 and metal
Between pressing plate 83, with the impact by heat transferring medium to front tube sheet for preventing from coming from tube side imported equipments and parts 10, and preceding pipe is avoided
Plate or heat exchanger tube are excessively heated, and deform.
In the present embodiment, two-layer before and after the thermal insulating filling includes, and above one layer of thermal insulating filling be resistance to erosion heat-barrier material (such as
Cotton)；Each gear pipe 84 is set in outside heat exchanger tube 90, and the mouth of pipe external diameter of heat exchanger tube 90 is slightly less than the internal diameter for keeping off pipe 84,
And the external diameter for keeping off pipe 84 is more than the pore external diameter of pressing plate, departed from pressure guard, and will gear pipe 83 and the mutually weldering of heat exchanger tube 90
Connect and be fixed together.When high temperature by heat transferring medium from tube side imported equipments and parts enter high-temperature region heat exchanger 40 after, before one layer
Resistance to erosion heat-barrier material can prevent from directly washing away front tube sheet impact by heat transferring medium, the thermal insulating filling of later layer can prevent pipe
Between heat transferring medium communicated with heat exchanger tube.
Refer to shown in Fig. 1,8,9, in the present embodiment, be arranged between the first high temperature section 41 and tube side imported equipments and parts 10
Front tube sheet 80 be not retained in together mutually with shell and tube side imported equipments and parts 10, i.e., be convexly equipped with raised 105 by shell
And host cavity 106 is formed with outside, in the present embodiment, the projection is arranged in the inner chamber of shell in a ring, above-mentioned
Front tube sheet 80 is located in host cavity 106, i.e., described front tube sheet 80 is abutted by raised 105 and prevents front tube sheet inlet cavity
It is interior, and the front tube sheet internal diameter of the external diameter less than the host cavity 106 of shell, but internal diameter and tube side more than raised 105 enter
The external diameter of mouthpiece 10, therefore, front tube sheet 80 is limited between first high temperature section 41 and tube side imported equipments and parts 10, is had
Being shunk freely when expanding with heat and contract with cold before and after being heated beneficial to front tube sheet.And the front tube sheet 80, thermal insulating filling 82 and metal platen
83 constitute a bobbin carriages, and bearing 200 are installed on the downside of bobbin carriage, are heated inequality in front tube sheet 80 and metal platen 83
Under situation, the bearing 200 is conducive to adjusting being thermally deformed for front tube sheet 80 and metal platen 83, in case front tube sheet and metal
The excessive deformation of pressing plate.In the present embodiment, the seat supports are in the downside of front tube sheet 80.
If heat transferring medium flows out after high temperature heat exchange from the shell-side outlet 43 of the first high temperature section 41, therefore, go out in the shell side
The shell of mouth expands phenomenon because being heated, in the present embodiment, in the shell-side outlet of first high temperature section 41
43 is in bell mouth shape, and is provided with several expansion joints 60 towards junction between end and pipe in bell mouth shape in the shell-side outlet 43,
The expansion joint 60 around shell-side outlet surrounding, relatively existing high temperature resistant heat exchanger, expansion joint can improve course outlet shape
Become, when even the temperature on right side is more than the temperature in left side, the dynamics that the right side is stretched will be greater than the position in left side, the expansion
Section 60 set it is adjustable between the first high temperature section and pipe between surrounding be heated the expanding with heat and contract with cold of inequality, prevent front tube sheet 80 and shell
The factor such as be heated and be breached, extend the service life of high temperature resistant heat exchanger.In the present embodiment, the tube side import simultaneously
Part is interconnected with high-temperature region heat exchanger by several expansion joints, the shell-side outlet part and low-temperature space heat exchanger
Interconnected also by several expansion joints, can improve and cleavage phenomenon occurs because being heated inequality each other.
Above-mentioned implementation method is better embodiment of the present invention, and the present invention can also use and mode is implemented as follows certainly：
As shown in Figure 10, above-mentioned bearing may also set up a pair, and be separately mounted to the both sides of high temperature resistant heat exchanger, each crossbeam
