Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-9, the present invention provides a technical solution: a heat exchange intensifying device for a power plant, including a bracket 1. An inner shell 2 is fixedly connected to the upper side of the bracket 1. A left spherical shell 3 is fixedly connected to the left end of the inner shell 2. A right spherical shell 4 is fixedly connected to the right side of the inner shell 2. A partition 5 is fixedly connected to the inner wall of the left spherical shell 3. A left orifice plate 6 is fixedly connected to the left side of the partition 5. The outer wall of the left orifice plate 6 is fixedly connected to the inner wall of the left spherical shell 3. A right orifice plate 7 is fixedly connected to the right side of the inner wall of the inner shell 2. A plurality of fixing holes are provided on both the right orifice plate 7 and the left orifice plate 6. A heat exchange tube 8 is fixedly connected to the inner wall of the fixing hole. A plurality of flow guiding plates 9 are fixedly connected to the heat exchange tube 8. The plurality of flow guiding plates 9 are arranged up and down in a staggered manner. An outer shell 10 is fixedly connected to the outer wall of the inner shell 2. The interior of the outer shell 10 does not contact the outer wall of the inner shell 2. An air extraction pipe 11 is fixedly connected to the side wall of the outer shell 10. A heat medium outlet 12 is fixedly connected to the lower right side of the bracket 1. A heat medium inlet 13 is fixedly connected to the upper left side of the inner shell 2. A refrigerant outlet 14 is fixedly connected to the upper side of the left spherical shell 3. A refrigerant inlet 15 is fixedly connected to the lower side of the left spherical shell 3. The distal ends of the heat medium outlet 12, the heat medium inlet 13, the refrigerant outlet 14, and the refrigerant inlet 15 all penetrate through the outer shell 10 and extend to the outside of the outer shell 10. A vibration mechanism 16 is provided on the upper side of the outer shell 10. An exhaust mechanism 17 is provided at the lower part of the bracket 1. A power storage component 18 and a control component 19 are provided on the upper surface of the rear part of the bracket 1. The connection part between the inner shell 2 and the right spherical shell 4 bulges outwards, and the connection part between the inner shell 2 and the right spherical shell 4 extends to the outside of the outer shell 10. A vacuum environment is formed between the outer shell 10 and the inner shell 2;

[0032] During use, the high-temperature heat medium is discharged into the interior of the inner shell 2 through the heat medium inlet 13, and then discharged from the heat medium outlet 12 after flowing around a plurality of flow guiding plates 9. The low-temperature refrigerant is discharged into the lower part of the interior of the left spherical shell 3 through the refrigerant inlet 15, and then discharged into the interior of the right spherical shell 4 through the lower heat exchange tube 8. During this process, the hot and cold media exchange heat. The heated refrigerant discharged into the interior of the right spherical shell 4 is discharged into the upper part of the interior of the left spherical shell 3 through the upper heat exchange tube 8 and then discharged through the refrigerant outlet 14, thereby completing the heat exchange effect;

[0033] And during use, the inner shell 2, the left spherical shell 3, and the right spherical shell 4 are all wrapped by the outer shell 10. The space between the outer shell 10 and the inner shell 2 can be evacuated through the air extraction pipe 11, thereby blocking the heat leakage of the inner shell 2, so that the heat of the heat medium can be efficiently utilized;

[0034] The vibration mechanism 16 includes a fixed ring 601. The inner wall of the fixed ring 601 is fixedly connected to the outer wall of the heat exchange tube 8. A connecting column 602 is fixedly connected to the upper side of the fixed ring 601. The upper end of the connecting column 602 penetrates through the inner shell 2 and the outer shell 10 and extends to the upper side of the outer shell 10. The upper end of the connecting column 602 is fixedly connected to a high-frequency vibration motor 605. A fixed frame 603 is fixedly connected to the upper side of the outer shell 10. A spring 604 is fixedly connected to the lower side of the inner wall of the fixed frame 603. The upper end of the spring 604 is fixedly connected to the lower side of the high-frequency vibration motor 605. An insertion port 606 is formed at the connection between the inner shell 2 and the right spherical shell 4. A heat conducting sheet 607 is inserted into the insertion port 606. A thermoelectric power generation sheet 608 is fixedly connected to the outer wall of the heat conducting sheet 607. A number of thermoelectric power generation sheets 608 are arranged on the outer side of the inner shell 2. The thermoelectric power generation sheet 608 is electrically connected to the control component 19. The power storage component 18 is electrically connected to the control component 19. The high-frequency vibration motor 605 is electrically connected to the control component 19;

[0035] During the use process, the heat inside the inner shell 2 dissipates outward through the connection between the inner shell 2 and the right spherical shell 4, causing the temperature at the connection between the inner shell 2 and the right spherical shell 4 to rise. And because the heat conducting sheet 607 is inserted into the inner parts of the inner shell 2 and the right spherical shell 4, the temperature on one side of the thermoelectric power generation sheet 608 will rise, and then the thermoelectric power generation sheet 608 supplies power to the power storage component 18 through the control component 19, enabling the power storage component 18 to be charged. When the voltage inside the power storage component 18 reaches the preset threshold, the power storage component 18 supplies power to the high-frequency vibration motor 605 through the control component 19, briefly starting the high-frequency vibration motor 605, so that the high-frequency vibration motor 605 vibrates under the support of the spring 604. Then the high-frequency vibration motor 605 drives the connecting column 602 and the heat exchange tube 8 to vibrate, breaking the thermal boundary layer between the cold and hot media, and thus improving the heat exchange efficiency;

[0036] The exhaust mechanism 17 includes a connecting pipe 701. The lower end of the connecting pipe 701 is fixedly connected to the upper right part of the inner shell 2. The upper end of the connecting pipe 701 is fixedly connected to an air supply pipe 702. The other end of the air supply pipe 702 is provided with a secondary heat exchanger 703. The lower side of the secondary heat exchanger 703 is fixedly connected to the outer wall of the support 1. One end of the air supply pipe 702 is connected to the heat medium inlet of the secondary heat exchanger 703. A cold water pipe 704 is fixedly connected to the heat medium outlet of the secondary heat exchanger 703. The other end of the cold water pipe 704 is fixedly connected to a cooling tank 705. A drain pipe 706 is fixedly connected to the rear side of the cooling tank 705. A heat conducting sheet 707 is arranged on the upper side of the cooling tank 705. The outer wall of the heat conducting sheet 707 is fixedly connected to the outer wall of the thermoelectric power generation sheet 608. The other end of the heat conducting sheet 707 extends into the cooling tank 705. The refrigerant inlet and the refrigerant outlet of the secondary heat exchanger 703 are respectively connected to the branched cold medium. The inside of the cooling tank 705 is communicated with the inside of the cold water pipe 704;

[0037] During use, gases such as vapor in the heat medium will be discharged into the secondary heat exchanger 703 through the air supply pipe 702 after moving to the right side inside the inner shell 2. Since the inside of the secondary heat exchanger 703 passes through low-temperature refrigerant, the high-temperature gas will heat the low-temperature refrigerant after passing through the secondary heat exchanger 703, and the high-temperature gas releases heat and condenses. The condensed water is discharged into the cooling tank 705 through the air supply pipe 702, thereby avoiding excessive gas remaining inside the inner shell 2 and preventing uneven heat exchange in part;

[0038] The condensed water discharged into the cooling tank 705 will be discharged to the next treatment process through the drain pipe 706. During this process, the low-temperature condensed water continuously flows through the lower side of the heat conduction fin 707, and the heat conduction fin 707 conducts away the heat from the cold side of the thermoelectric generator 608. Therefore, the condensed water continuously cools the lower side of the heat conduction fin 707, and the heat conduction fin 707 controls the temperature of the cold side of the thermoelectric generator 608, thereby ensuring the working efficiency of the thermoelectric generator 608 and enabling the high-frequency vibration motor 605 to work frequently, promoting the heat exchange efficiency.
