Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flue gas heat exchange, in particular to a heat exchange device convenient to install and fix. BACKGROUND

[0002] The "wet electrostatic spraying" process requires special additives in the enamel mold material, and the requirements for the base material of the enameled steel plate are extremely strict. Before enameling, the steel plate needs to go through complete alkaline washing, acid washing, and rinsing processes (which can strengthen the bonding force of the enamel and the steel plate). The ordinary dry process does not use additives, and the steel plate pretreatment usually only uses one alkaline washing.

[0003] In addition, it should be noted that the "wet electrostatic spraying" process is different from the "wet dipping" or "immersion" process. The "dipping" process does not have an electrostatic adsorption process, and due to the effect of gravity (the glaze will have a hanging phenomenon), the adhesion, thickness uniformity, surface finish, porosity, and edge wrapping rate of the product are far from the level of the "electrostatic spraying" process. Both theoretically and practically, it can be proved that it is superior. The products produced by the "wet electrostatic spraying" process are superior to the "dry process" in terms of corrosion resistance, edge wrapping, and flexibility, and can fully ensure the performance and service life requirements of the heat exchange element.

[0004] Loose and broken heat exchange elements can seriously affect the stable operation of the unit. The falling of loose heat storage elements can cause the air preheater to jam, causing the air preheater current to fluctuate and the air preheater to trip; at the same time, in the primary air duct, the primary air fan is arranged directly below the air preheater, and the falling of loose heat storage elements can easily cause the primary air fan impeller to fail and damage, affecting the safe operation of the primary air fan; the falling of loose heat storage elements can also cause the primary air fan outlet baffle to jam, and the primary air flow cannot be normally adjusted during operation, threatening the safe and stable operation of the unit. The falling of loose heat storage elements reduces the heat exchange area and the heat exchange between flue gas and air, and the primary air and secondary air temperatures cannot reach the design values, resulting in high flue gas temperature and affecting the economic efficiency of the furnace combustion.

[0005] Therefore, a heat exchange device convenient to install and fix is designed. SUMMARY

[0041] Embodiment 2

[0042] With reference to Figures 1-3 、 Figures 5-8 , the embodiment provides a heat exchange device convenient to install and fix, and the embodiment introduces a use mode of the application,

[0043] The support frame 101 is a square or rectangular frame structure, and the moving groove 101a and the buckle groove 101b are arranged on opposite sides of the support frame 101, and a person skilled in the art can select a support frame 101 containing a plurality of moving grooves 101a and buckle grooves 101b according to the needs, which is used for assembling the heat exchange device. The heat exchange element 300 is fixed in the inner frame of the support frame 101 and is carried by the carrier plate 101c, the volume of the heat exchange element 300 is slightly larger than the volume of the inner frame of the support frame 101, so as to ensure the fixation of the heat exchange element 300.

[0044] The connecting assembly 200 is placed in the moving groove 101a, and the connecting assembly 200 is used for connecting the support frame 101 and the support frame 101, and the initial state of the connecting assembly 200 is as shown in Figure 5 When the support frame 101 needs to be connected, first, the two support frames 101 are placed side by side, and one of the support frames 101 is moved along the Y axis by a distance, so that the end of the buckle piece 202 in the moving groove 101a is parallel to the end of the buckle groove 101b on the other support frame 101. The two support frames 101 are brought together, the buckle piece 202 enters the buckle groove 101b of the other support frame 101, and due to extrusion, the buckle piece 202 slides along the inclined surface on the buckle groove 101b.

[0045] In the process, the longitudinal fixed block 101b-2 is in contact with the rotating plate 202c, the rotating plate 202c is stressed, and due to the limiting of the rotating plate 202c by the clamping block 202d-2 on the telescopic plate 202d, the rotating plate 202c cannot rotate at this time. As the two support frames 101 approach each other, the longitudinal fixed block 101b-2 begins to contact the telescopic plate 202d, and the longitudinal fixed block 101b-2 exerts a longitudinal pushing force on the telescopic plate 202d, and the telescopic plate 202d is pushed, and the telescopic elastic element 202d-1 on the telescopic plate 202d is extruded, and the telescopic plate 202d moves longitudinally with the longitudinal fixed block 101b-2, and then the limiting of the rotating plate 202c by the clamping block 202d-2 on the telescopic plate 202d disappears. At this time, due to the action of the first elastic element 201b, the sliding block 201a drives the moving element 201 and the buckle element 202 to rebound into the moving groove 101a, and the longitudinal fixed block 101b-2 also drives the rotating plate 202c to move in the opposite direction, and when the rotating plate 202c hits the inner wall of the longitudinal limiting groove 202b, the movement stops, and the above structural elements jointly fix the two support frames 101 in the horizontal direction.

[0046] Among them, the angle of the initial position of the rotating plate 202c is the same as the angle of the inclined surface on the buckle groove 101b; the clamping block 202d-2 and the longitudinal fixed block 101b-2 can be treated as inclined surfaces, which facilitates the extrusion of the longitudinal fixed block 101b-2 when moving the rotating plate 202c, and avoids being limited by the clamping block 202d-2.

[0047] In the above process, when the longitudinal fixed block 101b-2 drives the telescopic plate 202d to reach the limit position, the horizontal limiting groove 202a also reaches the position parallel to the horizontal fixed block 101b-1, and when the first elastic element 201b drives the moving element 201 and the buckle element 202 to rebound into the moving groove 101a, the horizontal limiting groove 202a also moves, and stops when reaching the horizontal fixed block 101b-1, and the horizontal fixed block 101b-1 fixes the overall structure in the longitudinal direction.

[0048] Embodiment 3

[0049] Reference Figures 1-3 , Figures 5-8 The embodiment provides a heat exchange device which is convenient to install and fix, and introduces a use mode of the heat exchange device,

[0050] The heat exchange element 300 will be aged and damaged during use, so it needs to be repaired or replaced in time. When the support frame 101 needs to be disassembled, the skilled person in the art needs to press the disassembly button 203, which will push the moving piece 201 and the buckle piece 202 to move forward. During the moving process, the transverse fixing block 101b-1 is separated from the transverse limiting slot 202a, and the longitudinal limiting disappears. At the same time, the longitudinal fixing block 101b-2 also leaves the close contact with the rotating plate 202c and moves reversely. While the rotating plate 202c rotates due to the action of the rotating shaft 202c-2 and the rotating elastic piece 202c-3, the plate body 202c-1 will rotate with the movement of the longitudinal fixing block 101b-2. When the longitudinal fixing block 101b-2 reaches the end of the clamping block 202d-2, the telescopic elastic piece 202d-1 is stretched, and the telescopic plate 202d rebounds to limit the rotation of the rotating plate 202c again.

[0051] At this time, the skilled person in the art applies a longitudinal pushing force to the two support frames 101, and the longitudinal fixing block 101b-2 and the buckle piece 202 slide on the surface of the rotating plate 202c and the inclined surface of the buckle slot 101b at the same time, until the buckle piece 202 is separated from the buckle slot 101b, and the disassembly is completed. Then the heat exchange element 300 to be replaced is taken out, a new heat exchange element 300 is replaced, and the two support frames 101 are installed.
