Description

Technical Field

[0001] The invention relates to the field of evaporators, and in particular to waste gas recovery equipment for evaporators. Background Art

[0002] The evaporator is a device used for heat exchange. During the industrial production process, a large amount of waste gas will be generated. This waste gas contains very high thermal energy. Recovering the heat energy in the waste gas through the evaporator to reduce the energy consumption of industrial production is one of the ways to develop green industry.

[0003] When the existing evaporator is in use, due to the uneven heating of the evaporator tube, a large number of bubbles will be generated in the evaporating liquid inside the evaporator tube. These bubbles adhere to the inner wall of the evaporator tube, which will isolate the evaporating liquid from the evaporator tube, making it difficult for the evaporator tube to absorb the heat of the exhaust gas, which is not conducive to the recovery of heat energy. At the same time, there may be certain particles and other debris in the exhaust gas. After the exhaust gas enters the evaporator, these particles will adhere to the outside of the evaporator tube, reducing the thermal conductivity of the evaporator tube, which is not conducive to the recovery of heat energy.

Moreover, when the adjustment plate 68 moves outward, the adjustment spring 611 is stretched. When the connecting shaft 61 moves downward, the extrusion rod 63 and the extrusion block 62 no longer squeeze each other, and the elastic force of the adjustment spring 611 causes the adjustment plate 68 and the crushing plate 69 to return to their original positions.

[0033] like Figure 3 and Figure 6As shown, the heat-equalizing structure 7 includes a self-rotating gear 71 slidably connected to the outside of each evaporating tube 11, a self-rotating gear ring 72 is arranged on the outside of the evaporating tube 11, and the self-rotating gear ring 72 is meshed with each self-rotating gear 71. A connecting ring 73 is fixedly connected to the outside of the self-rotating gear ring 72, and the connecting ring 73 is slidably arranged with the inner wall of the fixed shell 1. A fixed shaft 14 is rotatably connected to the lower inner wall of the fixed shell 1, and the fixed shaft 14 extends to the upper part of the collecting plate 12. A fixed sleeve is provided on the fixed shaft 14, and a fixed gear 15 is fixedly provided on the side wall of the collecting plate 12. The fixed gear ring 10 is arranged in meshing with the fixed gear 15. The motor 4 is fixedly connected to the bottom of the fixed housing 1 through a mounting bracket. The output end of the motor 4 is fixedly connected to a rotating rod 16. The rotating rod 16 penetrates the lower inner wall of the fixed housing 1 and extends to the interior of the fixed housing 1. The part of the rotating rod 16 located inside the fixed housing 1 and the fixed shaft 14 are fixedly sleeved with a transmission gear 13. The transmission gears 13 are meshed. After the motor 4 is started, its output end drives the rotating rod 16 to rotate. Under the action of the transmission gear 13, the fixed shaft 14 rotates accordingly. The fixed gear 15 fixedly sleeved on the fixed shaft 14 rotates together, so that the fixed gear ring 10 meshing with the fixed gear 15 rotates, so that the collecting plate 12 fixedly connected to the fixed gear ring 10 rotates, and the evaporation tube 11 and the distribution plate 9 rotate accordingly. When the evaporation tube 11 rotates, each evaporation tube 11 will rotate to the side where the exhaust gas enters, so that each evaporation tube 11 is heated more evenly. At the same time, during the rotation of the evaporation tube 11, the self-rotating gear 71 slidably sleeved on the evaporation tube 11 rotates accordingly. Under the action of the self-rotating gear ring 72, the self-rotating gear 71 rotates when it rotates, bringing The evaporation tube 11 rotates together, and the evaporation liquid inside it rotates together when the evaporation tube 11 rotates, and centrifugation is performed. As the centrifugation proceeds, objects with high density are located at the lower side of the outer side of the inside of the evaporation tube 11, and objects with low density are located at the upper side of the inner side of the inside of the evaporation tube 11, so that the bubbles attached to the inner wall of the evaporation tube 11 move to the inside of the evaporation tube 11, and the bubbles at the lower end of the evaporation liquid quickly float to the liquid surface of the evaporation liquid to facilitate the bubble breakage. After the bubbles on the inner wall of the evaporation tube 11 leave, the contact area between the liquid and the inner wall of the evaporation tube 11 increases, so as to facilitate the heat absorption and evaporation of the evaporation liquid;

[0034] like Figure 7 and Figure 8As shown, the scraping structure 8 includes a scraping plate 81 sleeved on the outside of each evaporation tube 11, and a mounting plate 82 is slidably connected to the side wall of each scraping plate 81, and one end of each mounting plate 82 away from the scraping plate 81 is slidably connected to the inner wall of the connecting ring 73, and an annular groove corresponding to the mounting plate 82 is provided on each scraping plate 81 and the connecting ring 73.

During the rotation of the fixed shaft 14, under the action of the reciprocating screw slide groove, the reciprocating screw slider 83 will move up and down, thereby driving the connecting ring 73 to move up and down, so that the mounting plate 82 and the scraping plate 81 move up and down together to scrape the outer wall of the evaporation tube 11, so as to prevent the residual particles and other debris in the exhaust gas from adhering to the evaporation tube 11 and affecting the heat conduction of the evaporation tube 11;

[0035] like Figure 1 As shown, control valves are provided on both the liquid inlet pipe 2 and the exhaust pipe. The control valves are existing equipment and can adjust the opening of the liquid inlet pipe 2 and the exhaust pipe.

[0036] In the present invention, when the device is in use, the exhaust gas enters the fixed housing 1 from the exhaust pipe on one side and is discharged from the exhaust pipe on the other side, while the evaporative liquid enters the fixed housing 1 from the liquid inlet pipe 2, flows into the distribution plate 9 through the fixed sleeve 5, and then flows to the evaporation tube 11, absorbs heat in the evaporation tube 11 and evaporates into gas, which is discharged from the collecting plate 12 and the steam pipe 3;

[0037] Start the motor 4. After the motor 4 is started, its output end drives the rotating rod 16 to rotate. Under the action of the transmission gear 13, the fixed shaft 14 rotates accordingly, and the fixed gear 15 fixedly sleeved on the fixed shaft 14 rotates together, so that the fixed gear ring 10 meshing with the fixed gear 15 rotates, so that the collecting plate 12 fixedly connected to the fixed gear ring 10 rotates, and the evaporation tube 11 and the distribution plate 9 rotate accordingly. When the evaporation tube 11 rotates, each evaporation tube 11 rotates to the side where the exhaust gas enters, so that each evaporation tube 11 is heated more evenly. At the same time, during the rotation of the evaporation tube 11, the self-rotating gear 71 slidably sleeved on the evaporation tube 11 rotates accordingly. Under the action of the gear ring 72, the self-rotating gear 71 will rotate when it rotates, driving the evaporation tube 11 to rotate together. When the evaporation tube 11 rotates, it will drive the evaporation liquid inside it to rotate together and centrifuge. As the centrifugation proceeds, objects with high density will be located on the lower side of the outer side of the inside of the evaporation tube 11, while objects with low density will be located on the upper side of the inner side of the inside of the evaporation tube 11, so that the bubbles attached to the inner wall of the evaporation tube 11 move to the inside of the evaporation tube 11, and the bubbles at the lower end of the evaporation liquid quickly float to the surface of the evaporation liquid to facilitate the bubble breakage. After the bubbles on the inner wall of the evaporation tube 11 leave, the contact area between the liquid and the inner wall of the evaporation tube 11 increases, so as to facilitate the heat absorption and evaporation of the evaporation liquid.

[0038] When the distribution plate 9 rotates, the connecting shaft 61 and the connecting gear 64 rotate accordingly. Under the action of the connecting gear ring 65, the connecting gear 64 will rotate during the rotation process, thereby driving the connecting shaft 61 to rotate accordingly. During the rotation of the connecting shaft 61, the defoaming plate 67, the regulating plate 68 and the crushing plate 69 rotate accordingly to stir the liquid in the evaporating tube 11, so that the evaporating liquid is heated more evenly and the bubbles generated during the heating process are crushed. When the connecting shaft 61 rotates, under the action of the reciprocating spiral groove on the inner wall of the connecting rod 66, the connecting shaft 61 will reciprocate up and down, increasing the defoaming range of the defoaming plate 67 and other structures, and will also drive the extrusion rod 63 to move upward to squeeze the liquid. The rod 63 and the extrusion block 62 are pressed against each other, so that the extrusion rod 63 moves outward, driving the corresponding adjustment plate 68 to move outward. Under the action of the fixed support rod 612, each adjustment plate 68 moves outward, driving the crushing plate 69 to move together, crushing the bubbles attached to the inner wall of the evaporation tube 11, and avoiding the bubbles to affect the heat absorption of the liquid in the evaporation tube 11. When the adjustment plate 68 moves outward, the adjustment spring 611 stretches. When the connecting shaft 61 moves downward, the extrusion rod 63 and the extrusion block 62 no longer press against each other. The elastic force of the adjustment spring 611 makes the adjustment plate 68 and the crushing plate 69 return to their original positions, avoiding the crushing plate 69 always sticking to the inner wall of the evaporation tube 11.

[0039] During the rotation of the fixed shaft 14, under the action of the reciprocating screw slide groove, the reciprocating screw slider 83 will move up and down, thereby driving the connecting ring 73 to move up and down, so that the mounting plate 82 and the scraper plate 81 move up and down together to scrape the outer wall of the evaporator tube 11 to prevent the particles and other debris remaining in the exhaust gas from adhering to the evaporator tube 11 and affecting the heat conduction of the evaporator tube 11. At this time, the self-rotating gear 71 slidably mounted on the outside of the evaporator tube 11 will move with the scraper plate 81, and the self-rotating gear ring 72 will also move with the connecting ring 73 to ensure that the self-rotating gear 71 and the self-rotating gear ring 72 remain in a meshing state.
