It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] The present application provides a detachable high-temperature heat exchanger as shown in Figures 1-4 , comprising a heat exchange element 16 located at the middle position of the heat exchanger, a cold side inlet 10 located below the heat exchange element 16, a cold side outlet 3 located above the heat exchange element 16, a hot side inlet 12 located at the left side of the heat exchange element 16, and a hot side outlet 7 located at the right side of the heat exchange element 16; the cold side inlet 10 has a lower support 15 on the side; the cold side outlet 3 is provided with a sealing structure around;

[0030] The heat exchange element 16 is connected with the cold side outlet 3 through an upper tube sheet 17, and the heat exchange element 16 is connected with the cold side inlet 10 through a lower tube sheet 8; the lower tube sheet 8 and the cold side inlet 10 are the same plate, and the entire equipment is supported on this plate, so as to be fixed on the foundation through the lower support 15;

[0031] The cold side outlet 3 is connected with a cold side inlet flange 2, and the cold side inlet 10 is connected with a cold side inlet flange 9;

[0033] The sealing structure 1 surrounds the cold side outlet 3, and one side of the sealing structure 1 is a hot side passage plate; the hot side passage plate is a hot side inlet passage plate, a hot side outlet passage plate and a hot side side plate 4; the hot side side plate 4 is internally provided with a cotton hanging two 11;

[0034] As shown in Figures 8-11As shown, the lower support 15 consists of connecting plate 15-1, connecting plate 15-2, fixing ring 15-3, anchor bolt 15-4, support leg 15-5, support ring 15-6, and base plate 15-7. The entire equipment is supported by the cold side inlet, and then by the lower support. The support ring 15-6 surrounds the cold side inlet 10 and is connected to connecting plate 15-1. The support leg 15-5 is connected to connecting plate 15-2. Connecting plate 15-1 and connecting plate 15-2 are connected by anchor bolt 15-4. The fixing ring 15-3 is fitted onto connecting plate 15-1. 1. The upper part has openings of varying sizes. One is a small hole 15-1c, used for positioning. The first long-leg hole 15-1a and the second long-leg hole 15-1d are the same shape but different in direction, facilitating expansion and fixing the direction. The other is a large round hole 15-1b, which facilitates expansion but does not fix the direction. The second connecting plate 15-2 also has openings, all the same as the small hole 15-1c, and corresponding to the small hole 15-1c, the first long-leg hole 15-1a, the second long-leg hole 15-1d, and the large round hole 15-1b, respectively, for fixing purposes. The fixing ring 15-3 is a concentric ring, with an inner diameter consistent with the second hole of the connecting plate and an outer diameter larger than the large round hole of the connecting plate.

[0035] like Figure 5 and Figure 6 As shown, the sealing structure 1 consists of bolt 1-1, pressure plate 1-2, sealing gasket 1-3, intermediate plate 1-4, expansion joint 1-5, sealing rope A1-6, baffle A1-7, outer folding plate 1-8, sealing bag 1-9, sealing rope B1-10, inner folding plate 1-11, and baffle B1-12. Pressure plate 1-2 is connected to the hot-side outlet 7, cotton hanger 2 11, or hot-side inlet 12 via bolt 1-1. A sealing gasket 1-3 and intermediate plate 1-4 are placed in the middle. The sealing gasket is welded to the expansion joint 1-5 via the intermediate plate 1-4. The sealing gasket 1-3 wraps around the intermediate plate 1-4. The manufacturing method is described in [link to manufacturing instructions]. Figure 7 Flip the sealing gasket 1-3 360 degrees and then wrap it around the intermediate plate 1-4; the expansion joint 1-5 has a sealing rope A1-6 at the bottom, and a baffle A1-7 is provided at the bottom of the sealing rope A1-6. The baffle A1-7 is welded to the inner folding plate 1-11, but not to the outer folding plate 1-8; the outer folding plate 1-8 has a sealing bag 1-9 at the bottom, and the outer folding plate 1-8 is welded to the cold side outlet 3. The outer folding plate 1-8 has a sealing rope B1-10 at the bottom, and a baffle B1-12 is provided at the bottom of the sealing rope B1-10. The baffle B1-12 is welded to the inner folding plate 1-11, but not to the cold side outlet 3.

[0036] Expansion joint 1-5 is a metal expansion joint; expansion joint 1-5 is welded to intermediate plate 1-4;

[0037] Sealing gaskets 1-3 are made of aluminum silicate. The two-layer wrapping structure ensures sealing and increases the upward and downward limits.

[0038] Sealing ropes A1-6 and B1-10 are made of aluminum silicate rope or graphite rope;

[0039] The sealing packs 1-9 are compressible and expandable aluminum silicate packs to prevent the sealing ropes B1-10 from entering between the outer folding plate 1-8 and the inner folding plate 1-11, which would affect the operation and recovery of the equipment.

[0040] When the equipment is running, cold-side gas is first introduced through the cold-side inlet 10, and then hot-side gas is introduced through the hot-side inlet 12. Support rings 15-6 are the zero-point of expansion. The length of heat exchange element 16 is initially set to L, the width to W, and the height to H. Because the temperature of the hot-side gas is too high during operation, heat exchange element 16 expands, becoming L+X2 in length, W+X3 in width, and H+X1 in height. The cold-side outlet expands upwards in the height direction, causing the outer folding plates 1-8 to move upwards, while the inner folding plates 1-11 remain unchanged. The width and length extend outwards in all directions, causing the cold-side outlet 3 to become longer and wider, extruding... The sealing rope B1-10 is compressed, making it taller and thinner. Simultaneously, as the outer folding plate 1-8 extends upwards, the sealing package 1-9 expands, preventing the sealing rope B1-10 from entering between the outer folding plate 1-8 and the inner folding plate 1-11, thus ensuring a seal. The cotton lining inside the hot-side outlet 7, hot-side side plate 4, and hot-side inlet 12 remains at room temperature and does not expand. Therefore, when the outer folding plate 1-8 is driven upwards and outwards by the cold-side outlet 3, it compresses the sealing rope A1-6, making it taller and thinner. The upper expansion joint 1-5 controls the sealing rope A1-6 within a fixed range, ensuring a seal. When the expansion joint 1-5 reaches its limit, the upper bolt connection structure activates, ensuring the sealing rope A1-6 remains within a fixed range and maintaining a seal. The entire upper sealing structure ensures the separation of hot and cold side gases and also solves the problem of equipment expansion.

[0041] When the equipment is running, due to heat, the tube sheet 8 and the cold-side inlet 10 expand outward, thereby causing the support ring 15-6 to extend in all directions. The connecting plate 15-1, along with the anchor bolts 15-4, moves in all directions, while the connecting plate 15-2 remains fixed, ensuring that the support legs 15-5 and 15-7 do not move. However, at this time, 15-1c is a fixed point and does not move. 15-1a moves to the left along the long waist hole, 15-1d moves forward, and 15-1d moves to the left front. The various holes on 15-1 ensure the possibility of the support ring 15-6 extending outward, thus solving the problem of expansion at the bottom of the equipment.

[0042] When the equipment is under maintenance, bolts 1-1 and anchor bolts 15-4 can be removed. At this time, the entire internal component (see...) can be removed. Figure 12 The tubes can be pulled out to facilitate cleaning of dust from the outside of the tubes and to facilitate the replacement of damaged heat exchange tubes, thereby ensuring the long-term effective operation of the heat exchanger.

[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
