The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0047] For example, see Figure 1-14 , the present invention provides the following technical solutions: A high-temperature flue gas heat exchanger, specifically, comprises a heat exchange component 1, a smoke inlet component 2 is fixed on the top of the heat exchange component 1; the heat exchange component 1 comprises a box body 3, a water inlet component 4 inserted in the box body 3 and a plurality of heat-conducting components 5 slidably arranged on the water inlet component 4, the smoke inlet component 2 comprises a smoke inlet component 6, a displacement component 7 slidably arranged in the smoke inlet component 6 and a blocking component 8 slidably arranged in the smoke inlet component 6; the box body 3 comprises a heat exchange box body 301, a plurality of water inlet pipes 302 are connected to one outer side surface of the heat exchange box body 301, and a plurality of water outlet pipes 303 are connected to the other outer side surface of the heat exchange box body 301; the water inlet component 4 comprises two U-shaped plates 401 arranged opposite to each other, The inner side surfaces of the two U-shaped plates 401 are penetrated by a plurality of connecting pipes 402 that are fixedly sleeved and fitted between the water inlet pipe 302 and the water outlet pipe 303; the heat-conducting member 5 includes a heat exchange tube 501 slidably arranged on the connecting pipe 402, a conical cover 502 is fixed on the inner wall of the heat exchange tube 501, a plurality of fins 503 are fixed on the outer wall of the heat exchange tube 501, high-temperature resistant flexible sleeves 504 are fixed on both ends of the heat exchange tube 501, the inner walls of the two high-temperature resistant flexible sleeves 504 are respectively fixedly connected to the outer walls of the two connecting pipes 402, the end of the heat exchange tube 501 is located inside a high-temperature resistant flexible sleeve 504 and an elastic spring 505 is fixed therein, and the end of the elastic spring 505 is fixedly connected to the end of the connecting pipe 402.

[0048] The specific application of the first embodiment is as follows: in the later stage of heat exchange of the heat exchanger, the external water-cooling liquid is pumped intermittently by the water pump (the intermittent pumping method of the water pump is controlled by the water pump pulse, and the elastic spring 505 matches the impact force of the water pump pulse control), so that the external water-cooling liquid intermittently enters the interior of the plurality of connecting pipes 402 from the plurality of water inlet pipes 302, and then enters the interior of the heat exchange tube 501 through the heat exchange of the water-cooling liquid, and absorbs heat from the flue gas in the heat exchange box 301, so that the water-cooling liquid after heat absorption is discharged from the plurality of water outlet pipes 303 together with the heat in the flue gas, so as to be used later. In the whole heat exchange process, the cone 404 fixedly connected to the inner wall of the heat exchange tube 501 is pressed by the intermittent water flow power of the water-cooling liquid. The shaped cover 502 generates a pushing force, so that the elastic spring 505 fixedly connected between the heat exchange tube 501 and the connecting tube 402 is intermittently and repeatedly compressed, and combined with the elastic force of the elastic spring 505, the heat exchange tube 501 is driven to make a horizontal reciprocating horizontal movement between a group of relatively arranged connecting tubes 402, thereby making the plurality of fins 503 arranged on the side surface of the heat exchange tube 501 to make a horizontal reciprocating horizontal movement, and through the horizontal reciprocating movement process of the plurality of fins 503 arranged on the side surface of the heat exchange tube 501, the flue gas inside the heat exchange box 301 is accelerated, thereby improving the heat exchange effect between the plurality of fins 503 and the flue gas inside the heat exchange box 301, and improving the later heat exchange efficiency.

[0049] For example 2, please refer to Figure 1-14 , the second embodiment is improved on the basis of the first embodiment as follows. Specifically, two symmetrical guide grooves 403 are provided on the outer peripheral side surfaces of the plurality of connecting pipes 402; two symmetrical guide rails 506 are fixed on the inner wall of the heat exchange tube 501, and the two guide rails 506 are respectively slidably arranged to cooperate with the two guide grooves 403; the water inlet member 4 also includes two symmetrically arranged sleeves 404, and the inner wall of the sleeve 404 is slidably arranged with two symmetrical sliding rods 405, and a circular baffle 406 is fixed at the center of the inner wall of the sleeve 404, and a first spring 407 is fixed between the opposite end surfaces of the circular baffle 406 and the two sliding rods 405, and the opposite end surfaces of the two sliding rods 405 are respectively slidably arranged with the two guide grooves 403. The U-shaped plate 401 is fixedly connected to one end face relative to another; two symmetrical first positioning cylinders 408 are fixed to one outer side face of the two U-shaped plates 401; a plurality of second positioning cylinders 304 are fixed to the inner bottom of the heat exchange box 301, and the first positioning cylinders 408 and the second positioning cylinders 304 are fixedly connected by bolts; the smoke inlet component 6 includes an upper box body 601 fixedly installed on the heat exchange box body 301, and a smoke inlet pipe 602 is connected to the outer top of the upper box body 601, and symmetrical two side baffles 603 are fixed to the outer top of the upper box body 601, one side of the two side baffles 603 is connected to the smoke inlet pipe 602, and one side of the two side baffles 603 is fixed to a sealing cover plate 604.

[0050] The specific application of the second embodiment is as follows: during the heat exchange process, the two guide rails 506 are respectively matched with the sliding arrangement between the two guide grooves 403, so that when the water-cooled liquid is heat exchanged later, the heat exchange tube 501 can only move horizontally between the two oppositely arranged connecting tubes 402, thereby preventing the heat exchange tube 501 from rotating in a circumferential direction between the two oppositely arranged connecting tubes 402 due to the flow of flue gas, thereby preventing the heat exchange tube 501 from affecting the later heat exchange process; Before the water-cooled liquid is exchanged for heat, the entire water inlet member 4 and the plurality of heat-conducting members 5 slidably arranged inside the water inlet member 4 are synchronously placed inside the heat exchange box 301. Then, inside the heat exchange box 301, the two relatively arranged U-shaped plates 401 are pushed, so that the first spring 407 is compressed, and the two U-shaped plates 401 are driven to move linearly toward each other on the opposite end surfaces of the sleeve 404 until the opposite end surfaces of the two groups of relatively arranged connecting pipes 402 are aligned with the water inlet pipe 302 and the outlet pipe 302. When the opposite end surface of the water pipe 303 is in a coaxial position, the pushing of the two oppositely arranged U-shaped plates 401 is stopped, and the elastic force of the compressed first spring 407 is used to drive the two groups of oppositely arranged connecting pipes 402 to be respectively inserted into the oppositely arranged water inlet pipes 302 and water outlet pipes 303, thereby completing the installation and positioning between the water inlet component 4 and the several heat-conducting components 5 slidably arranged inside the water inlet component 4 and the heat exchange box body 301, so as to carry out the subsequent flue gas heat exchange process.

Specifically, an externally threaded barrel 605 is provided on the outside of the smoke inlet pipe 602, and an internally threaded barrel 606 is threadedly connected to the outer wall of the externally threaded barrel 605. A guide tube 607 extending to the inside of the smoke inlet pipe 602 is fixed on the top of the internally threaded barrel 606, and a vertical groove 608 extending upward is provided at the bottom of the guide tube 607; the displacement member 7 includes a displacement rod 701 slidably arranged inside the guide tube 607, a second spring 702 located inside the guide tube 607 is fixed between the displacement rod 701 and the internally threaded barrel 606, and a vertical rail 703 slidably arranged inside the vertical groove 608 is fixed on the side surface of the displacement rod 701; the inner wall of the upper box body 601 A partition plate 609 is fixed, a slide groove 610 is provided on the top of the partition plate 609, a smoke inlet 611 is provided through the bottom of the slide groove 610, and limiting grooves 612 are provided on both inner side walls of the slide groove 610; the blocking member 8 includes a slide plate 801 slidably arranged inside the slide groove 610, the slide plate 801 slides with the two limiting grooves 612 on both sides, a plurality of third springs 802 are fixed on one side of the slide plate 801, and one side of the plurality of third springs 802 is fixedly connected to one side of the slide groove 610, and a rectangular opening 803 is provided through the top of the slide plate 801; a trapezoidal plate 804 is fixed on the top of the slide plate 801, and a limiting side plate 805 is fixed on one side of the trapezoidal plate 804; an extension is fixed on the end of the displacement rod 701 Rod 704, a contact ball 705 that fits with the inclined surface of the trapezoidal plate 804 is fixed at the bottom of the extension rod 704; a dust filter 613 is fixed to the inner wall of the smoke inlet duct 602, and a first hinge seat 614 is fixed to the end of the inner wall of the smoke inlet duct 602 away from the dust filter 613, and a hinge arm 615 is hingedly matched inside the first hinge seat 614, and an arc expansion plate 616 is fixed to one side of the hinge arm 615, and a second hinge seat 617 is fixed to the other side of the hinge arm 615, and a reciprocating arm 618 is hingedly matched inside the second hinge seat 617, and a hinge hole 619 is opened on one side of the reciprocating arm 618; a third hinge seat 706 that is hingedly matched on the hinge hole 619 is fixed to one side of the vertical rail 703; L-shaped rotating rods 620 are fixed on both opposite sides of the arc expansion plate 616, and a sliding rod 621 is fixed between the two L-shaped rotating rods 620; two symmetrical connecting blocks 622 are fixed inside the smoke inlet pipe 602 between the arc expansion plate 616 and the dust filter 613, and a rotating plate 623 is rotatably matched between the two connecting blocks 622 through a rotating shaft, a knocking rod 624 is fixed on the side of the rotating plate 623, and a knocking ball 625 is fixed on the end of the knocking rod 624, a U-shaped rotating plate 626 that slides with the sliding rod 621 is fixed on the side of the rotating plate 623, and an arc spring 627 is fixed between the U-shaped rotating plate 626 and the smoke inlet pipe 602; a smoke outlet pipe 305 is arranged at the outer bottom of the heat exchange box body 301.

[0052] The specific application of the third embodiment is as follows: before the heat exchanger is used, the entire heat exchanger is connected and fixed to the exhaust port of the smoke generating device, so as to perform corresponding dust removal and heat exchange operations on the smoke in the later stage. In the later stage of use, the smoke enters the smoke inlet duct 602 through the inlet end of the smoke inlet duct 602, and is filtered through the preliminary dust removal of the dust filter 613 to remove the dust in the smoke. After the preliminary dust removal, the dust in the smoke flows after the dust removal, and gradually generates thrust on the arc expansion plate 616 (the dust filter 613 is provided with a slanting extension extending to the inner wall of the arc expansion plate 616, but is not in contact with the arc expansion plate 616). There are two inclined smoke guide pipes with a certain distance between the inner walls of 16, and the outlet ends of the inclined smoke guide pipes are close to the inside and below the arc expansion plate 616, so that the smoke after preliminary dust removal can always flow near the bottom of the inner wall of the arc expansion plate 616, so as to provide thrust to the arc expansion plate 616 and avoid the smoke after preliminary filtration from affecting the rotation of the rotating plate 623), driving the articulated arm 615 articulated in the first articulated seat 614 to rotate downward, so that the articulated arm 615 articulated between the second articulated seat 617 and the third articulated seat 706 is pressed downward, driving the displacement rod 701 and the vertical rail 703 to rotate respectively. The guide tube 607 and the vertical groove 608 make a vertical downward movement. When the displacement rod 701 and the vertical rail 703 respectively make a vertical downward movement in the guide tube 607 and the vertical groove 608, the contact ball 705 fixed at the bottom of the extension rod 704 moves downward synchronously, and thereby generates a thrust on the trapezoidal plate 804, driving the slide plate 801 fixed at the bottom of the trapezoidal plate 804 to move horizontally in the slide groove 610 and the two limiting grooves 612 (the opposite sides of the slide plate 801 slide in the two limiting grooves 612 respectively to prevent the slide plate 801 from shaking up and down when it moves horizontally in the slide groove 610), so that the slide plate 801 fixed to the slide groove 610 is fixed to the guide tube 607 and the vertical groove 608. The third springs 802 between the plate 801 and the slide groove 610 are gradually compressed, thereby driving the rectangular opening 803 through the top of the slide plate 801 to gradually approach the smoke inlet 611, so that the smoke inlet 611 and the rectangular opening 803 are gradually staggered in a dislocated state, so as to facilitate the smoke after preliminary dust removal to enter the heat exchange box 301 through the rectangular opening 803 and the smoke inlet 611. At this time, the third springs 802 compressed between the slide plate 801 and the slide groove 610 increase the wind speed of the smoke discharged from the rectangular opening 803 and the smoke inlet 611 into the heat exchange box 301 under the action of their own elastic force, so as to carry out the later smoke heat exchange process; The flue gas flow after the dust removal generates thrust on the arc expansion plate 616, and the sliding rod 621 fixed between the two L-shaped rotating rods 620 will press down and slide on the inner wall of the U-shaped rotating plate 626, thereby driving the rotating plate 623 fixed on the side of the U-shaped rotating plate 626 to make an upward hinged rotation between the two connecting blocks 622, so that the knocking rod 624 fixed on the side of the rotating plate 623 and the knocking ball 625 fixed on the end of the knocking rod 624 synchronously make an upward rotation, and synchronously hit the fixed connection on the U-shaped rotating plate 626. The arc spring 627 between the rotating plate 626 and the smoke inlet pipe 602 is compressed (in the process of smoke circulation, when the compression amount of the arc spring 627 reaches the maximum, the sliding rod 621 is always located inside the U-shaped rotating plate 626 and will not be separated from the inner wall of the U-shaped rotating plate 626). After a period of dust removal and heat exchange, the flow of smoke stops (the flow of smoke stops, specifically through the timer control valve set at the inlet end of the smoke inlet pipe 602 to ensure that the smoke is not continuously in the whole heat exchange process). Continuously pass through to realize the periodic work of the dust filter knocking 613. During the installation of the timer control valve, one connecting flange of the timer control valve is sealed and connected to the connecting flange at the inlet end of the smoke inlet pipe 602, and then the other connecting flange of the timer control valve is sealed and connected to the connecting flange of the smoke exhaust port of the smoke generating equipment. The timer control valve here is the prior art, and the timer control valve is made of high-temperature resistant material, which is not drawn in the figure and will not be elaborated here. At this time, the compressed arc spring 627 begins to reset, driving the knocking rod 624 fixed on the side of the rotating plate 623 and the knocking ball 625 fixed on the end of the knocking rod 624 to press down and rotate synchronously, so that the dust filter 613 is repeatedly knocked by the elastic force of the arc spring 627 itself, so as to avoid the dust in the smoke from clogging the filter holes on the dust filter 613 after a long period of preliminary dust removal, thereby preventing it from affecting the later smoke removal and heat exchange process, and improving the later heat exchange effect.
