Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1-12 , the present invention provides a technical solution: a condensate heat energy recovery device based on biotechnology, comprising:

[0040] A heat exchange component disposed in the microalgae bioreactor 1 and used for uniform heat exchange. The heat exchange component includes a drive shaft 401 rotatably connected to the top cover 3 through a bearing. A plurality of heat exchange tubes 405 for injecting condensed water are fixedly provided on the surface of the drive shaft 401, so that the drive shaft 401 drives the heat exchange tubes 405 to rotate in the microalgae bioreactor 1 and uniformly exchange heat with the liquid in the microalgae bioreactor 1. A second connecting frame 406 is fixedly installed on the bottom surface of the heat exchange tube 405, and a lamp tube 412 for providing illumination is fixedly installed on the top of the second connecting frame 406. One end of the second connecting frame 406 away from the heat exchange tube 405 is rotatably connected to a fixed column 407 through a bearing. The fixed column 407 is rotatably connected to the bottom of the drive shaft 401 through a bearing, and the fixed column 407 is fixedly installed at the bottom of the inner wall of the microalgae bioreactor 1. A drive motor 411 is fixedly installed on the top of the drive shaft 401, and the drive motor 411 is fixedly installed on the top of the fixed frame 2. A plurality of first connecting frames 402 are fixedly installed on the surface of the drive shaft 401. The lamp tube 412 is fixedly installed at the bottom of the first connecting frame 402. A ring frame 403 is fixedly installed on the top of the first connecting frame 402, and a ring partition 404 is fixedly installed on the inner wall of the ring frame 403, so as to divide the ring frame 403 into a water inlet chamber and a water outlet chamber. Sealing rings 410 are respectively rotatably connected to the outer surface and the inner surface of the ring frame 403, and the sealing rings 410 are fixedly installed at the bottom of the top cover 3. Sealing rings are provided between the outer surface and the inner surface of the ring frame 403 and the sealing rings 410, and between the top of the ring frame 403 and the ring partition 404 and the top cover 3. The heat exchange tube 405 is fixedly embedded in the bottom of the ring frame 403. The heat exchange tube 405 is of a U-shaped structure, and the middle part of the heat exchange tube 405 is flat. The perimeter of the middle part of the heat exchange tube 405 is equal to the perimeter of the top of the heat exchange tube 405. The horizontal center line of the flat middle part of the heat exchange tube 405 and the midpoint of the fixed column 407 are located on the same straight line, so as to reduce the light shielding of the lamp tube 412 by the heat exchange tube 405. The two ends of the top of the heat exchange tube 405 are respectively communicated with the water inlet chamber and the water outlet chamber divided by the ring partition 404 of the ring frame 403. A liquid inlet pipe 408 and a liquid outlet pipe 409 are respectively fixedly embedded in the top of the top cover 3, and the liquid inlet pipe 408 and the liquid outlet pipe 409 are respectively communicated with the water inlet chamber and the water outlet chamber divided by the ring partition 404 of the ring frame 403;

[0041] When the above structure is in use, first add microalgae and nutrient solution into the microalgae bioreactor 1, and then drive the motor 411 to drive the drive shaft 401 to rotate. The drive shaft 401 drives the heat exchange tube 405 to rotate through the first connecting frame 402 and the annular frame 403. The condensed water with waste heat is discharged outward through the liquid inlet pipe 408, the water inlet cavity of the annular frame 403, the heat exchange tube 405, the water outlet cavity of the annular frame 403, and finally through the liquid outlet pipe 409. Since the middle part of the heat exchange tube 405 is flat, the heat exchange time of the condensed water can be prolonged, and the heat exchange efficiency can be improved. At the same time, when the heat exchange tube 405 rotates inside the microalgae bioreactor 1, the heat can be evenly distributed inside the microalgae bioreactor 1.

[0042] A cleaning assembly is arranged inside the microalgae bioreactor 1 and is used for cleaning the surfaces of the heat exchange tube 405 and the lamp tube 412. The cleaning assembly includes a plurality of third connecting frames 701 that reciprocate up and down along the fixed column 407. One end of the third connecting frame 701 corresponding to the position of the lamp tube 412 is fixedly installed with a cleaning ring 703, and the cleaning ring 703 is movably sleeved on the surface of the lamp tube 412. The surface of the heat exchange tube 405 is movably sleeved with a cleaning rubber sleeve 705, and both ends of the surface of the cleaning rubber sleeve 705 are respectively fixedly installed with hinge arms 704. The hinge arms 704 are hinged on the surface of the cleaning ring 703. Brushes are arranged on the inner walls of the cleaning ring 703 and the cleaning rubber sleeve 705, so that when the third connecting frame 701 drives the cleaning ring 703, the hinge arms 704 and the cleaning rubber sleeve 705 to reciprocate up and down, the surfaces of the heat exchange tube 405 and the lamp tube 412 can be cleaned. One end of the opposite surfaces of the first connecting frame 402 and the second connecting frame 406 is fixedly installed with a positioning column 702, and the positioning column 702 movably penetrates through and extends to the upper and lower ends of the third connecting frame 701;

[0043] By reciprocating up and down of the third connecting frame 701 along the fixed column 407, the third connecting frame 701 drives the cleaning ring 703, the hinge arms 704 and the cleaning rubber sleeve 705 to move up and down, and the brushes on the inner walls of the cleaning ring 703 and the cleaning rubber sleeve 705 respectively clean the dirt generated on the surfaces of the heat exchange tube 405 and the lamp tube 412 due to the growth of microalgae, thereby improving the heat exchange efficiency of the heat exchange tube 405.

[0044] It further includes a driving component for driving the third connecting frame 701 to reciprocate up and down. The driving component includes a face gear 501 fixedly installed at the bottom surface of the driving shaft 401. There are two driven gears 502 provided at the bottom of the face gear 501, and the two driven gears 502 do not mesh with the bottom of the face gear 501 simultaneously. A connecting shaft 503 is fixedly installed in the middle of each of the two driven gears 502, and the connecting shaft 503 movably penetrates and extends to both ends of the fixed column 407. The middle of the connecting shaft 503 has a regular polygon structure, and a driving roller 504 is movably sleeved on the surface of the middle of the connecting shaft 503. A transmission belt 505 is drivingly connected to the surface of the driving roller 504. One end of the transmission belt 505 away from the driving roller 504 is drivingly connected to a driven roller 506. A driven shaft 507 is fixedly installed in the middle of the driven roller 506, and the driven shaft 507 is rotatably connected to the middle of the fixed column 407 through a bearing. First movable blocks 509 and second movable blocks 510 are respectively fixedly installed at both ends of the inner wall of the transmission belt 505, and the first movable blocks 509 and the second movable blocks 510 are arranged vertically and staggeredly. A connecting pipe 511 is fixedly installed on the surface of the first movable block 509, and the connecting pipe 511 is fixedly installed at one end of the third connecting frame 701. A first movable groove 508 is opened in the middle of the fixed column 407 corresponding to the positions of the driving roller 504 and the driven roller 506, and the driving roller 504 and the driven roller 506 are respectively rotatably connected to the inner wall of the first movable groove 508. Guide blocks 512 are respectively fixedly installed at both ends of the inner walls of the first movable blocks 509 and the second movable blocks 510. A first guide groove 513 is opened at one end of the fixed column 407 corresponding to the positions of the guide blocks 512, and the guide blocks 512 are movably connected to the inner wall of the first guide groove 513;

[0045] When the above structure is in use, when the driving shaft 401 rotates, it will rotate relative to the fixed column 407, and the driving shaft 401 will drive the face gear 501 to mesh with the driven gears 502, and the driven gears 502 will drive the transmission belt 505 to drive through the connecting shaft 503 and the driving roller 504. Furthermore, the transmission belt 505 will drive the first movable blocks 509 and the second movable blocks 510 to move alternately, so that the first movable blocks 509 will drive the connecting pipe 511 to move up and down along the direction of the fixed column 407.

[0046] It further includes a reversing assembly for changing the rotation direction of the driving roller 504. The reversing assembly includes two support frames 601 rotatably connected to both ends of the connecting shaft 503 through bearings. One ends of the opposite faces of the two support frames 601 are fixedly installed with connecting arms 602. The connecting arms 602 movably penetrate and extend to both ends of the fixed column 407. A second moving groove 603 is formed in the middle of the fixed column 407 corresponding to the position of the connecting arm 602. A driving block 604 is fixedly installed at the bottom of the connecting arm 602 corresponding to the position of the second moving groove 603. Third moving grooves 605 are respectively formed at both ends of the fixed column 407 corresponding to the positions of the first moving block 509 and the second moving block 510. The inside of the third moving groove 605 is communicated with the inside of the driving block 604, and the two third moving grooves 605 are staggeredly arranged. Connecting plates 606 are respectively fixedly installed at the tops of the first moving block 509 and the second moving block 510. A driving column 607 is fixedly installed at the top of the connecting plate 606, and the driving column 607 is movably connected to the inner wall of the assisting assembly 608. The top of the connecting arm 602 is hinged with the assisting assembly 608, and the assisting assembly 608 is hinged to the inner wall of the second moving groove 603. The assisting assembly 608 includes a swinging telescopic sleeve and a return spring. When the connecting arm 602 moves and compresses the assisting assembly 608 to the critical state, that is, when both driven gears 502 are not engaged with the face gear 501 at this time, after the connecting arm 602 continues to move, the return spring in the assisting assembly 608 will quickly assist the connecting arm 602 to move, realizing the quick switching of the engagement state between the two driven gears 502 and the face gear 501, and avoiding the situation that the switching of the engagement state between the two driven gears 502 and the face gear 501 is not smooth;

[0047] When the above structure is in use, the first moving block 509 and the second moving block 510 move vertically and staggeredly relative to each other. When the second moving block 510 moves upward to the highest position, the driving column 607 squeezes the driving block 604 towards one end on the inner wall of the second moving groove 603, and the driving block 604 drives the connecting shaft 503 to move through the connecting arm 602 and the support frame 601, thereby switching the engagement state between the two driven gears 502 and the face gear 501, so as to change the rotation direction of the connecting shaft 503. On the contrary, when the first moving block 509 moves to the highest position, at this time the driving block 604 moves in the reverse direction, and the engagement state between the two driven gears 502 and the face gear 501 is switched again, so that during the continuous rotation of the driving shaft 401, the engagement state between the two driven gears 502 and the face gear 501 is switched differently, thereby realizing the vertical reciprocating up and down movement of the first moving block 509, and further enabling the first moving block 509 to drive the connecting pipe 511 to move vertically and reciprocally up and down, and enabling the connecting pipe 511 to drive the cleaning assembly to move continuously and reciprocally up and down for cleaning work.

[0048] Working principle: When in use, for this invention, first microalgae and nutrient solution are added into the microalgae bioreactor 1. Then, the driving motor 411 is powered on, and the driving motor 411 drives the driving shaft 401 to rotate. As a result, the driving shaft 401 drives the heat exchange tube 405 to rotate inside the microalgae bioreactor 1 through the first connecting frame 402 and the annular frame 403. Condensate water with waste heat is injected into the liquid inlet pipe 408, and the condensate water enters the water inlet cavity of the annular frame 403 through the liquid inlet pipe 408, and then enters the water outlet cavity of the annular frame 403 through the heat exchange tube 405, and finally is discharged outwards through the liquid outlet pipe 409. Since the middle part of the heat exchange tube 405 is flat, and the horizontal center line of the flat middle part of the heat exchange tube 405 and the midpoint of the fixed column 407 are on the same straight line, it can avoid the area where the heat exchange tube 405 blocks the light of the lamp tube 412. At the same time, because the middle part of the heat exchange tube 405 is flat, it can delay the flow rate of the condensate water, thereby prolonging the heat exchange time of the condensate water and improving the heat exchange efficiency. At the same time, when the heat exchange tube 405 rotates inside the microalgae bioreactor 1, the heat can be evenly distributed inside the microalgae bioreactor 1, and at the same time, the nutrient solution inside the microalgae bioreactor 1 can be rotated to make its nutrients evenly distributed;

[0049] When the driving shaft 401 rotates, since the fixed column 407 is fixed at the bottom of the inner wall of the microalgae bioreactor 1, the driving shaft 401 will rotate relative to the fixed column 407 when rotating, and the driving shaft 401 drives the face gear 501 to mesh with the driven gear 502. When the face gear 501 drives the driven gear 502 to rotate, the driven gear 502 drives the driving roller 504 to rotate through the connecting shaft 503, and the driving roller 504 and the driven roller 506 cooperate to drive the transmission belt 505 to drive, so that the transmission belt 505 drives the first movable block 509 and the second movable block 510 to move alternately, and the first movable block 509 drives the connecting pipe 511 to move up and down along the direction of the fixed column 407. By setting the guide block 512 and the first guide groove 513, the first movable block 509 and the second movable block 510 can move more stably;

[0050] Moreover, when the connecting pipe 511 moves up and down, the connecting pipe 511 drives the cleaning ring 703, the hinge arm 704 and the cleaning rubber sleeve 705 to move up and down through the third connecting frame 701, and the brushes on the inner walls of the cleaning ring 703 and the cleaning rubber sleeve 705 clean the dirt generated on the surfaces of the heat exchange pipe 405 and the lamp tube 412 due to microalgae growth, so as to avoid affecting the light intensity of the lamp tube 412. At the same time, since the perimeter of the flat structure of the heat exchange pipe 405 is equal to the perimeter of the top of the heat exchange pipe 405, the cleaning rubber sleeve 705 will always be closely attached to the surface of the heat exchange pipe 405 to clean the dirt on the surface of the heat exchange pipe 405, thereby effectively improving the heat exchange efficiency of the heat exchange pipe. By setting the positioning column 702, the movement of the third connecting frame 701 can be guided;

[0051] Since the first movable block 509 and the second movable block 510 move vertically and staggeredly relative to each other, when the second movable block 510 moves up to the highest position, the second movable block 510 drives the driving column 607 to move up along the inner wall of the third movable groove 605 through the connecting plate 606, so that the driving column 607 squeezes the driving block 604 towards one end along the inner wall of the second movable groove 603, and the driving block 604 drives the connecting shaft 503 to move through the connecting arm 602 and the support frame 601, thereby switching the meshing state of the two driven gears 502 and the face gear 501. That is, by switching the meshing state of the two driven gears 502 and the face gear 501 differently, the rotation direction of the connecting shaft 503 will be changed. Therefore, after the second movable block 510 moves to the highest position, the connecting shaft 503 rotates reversely, and drives the transmission belt 505 to drive reversely through the driving roller 504, so that the second movable block 510 moves downwards and the first movable block 509 moves upwards. Similarly, when the first movable block 509 moves to the highest position, the driving block 604 moves reversely, thereby switching the meshing state of the two driven gears 502 and the face gear 501 again, so that the driving shaft 401 will continuously rotate and switch the meshing state of the two driven gears 502 and the face gear 501 differently, thereby realizing the vertical reciprocating up and down movement of the first movable block 509, and further enabling the first movable block 509 to drive the connecting pipe 511 to move vertically and reciprocally up and down, and enabling the connecting pipe 511 to drive the cleaning assembly to continuously reciprocate up and down for cleaning work;

[0052] By providing an assisting component 608 which includes a swing telescopic sleeve and a return spring, when the connecting arm 602 moves and compresses the assisting component 608 to a critical state, that is, when both driven gears 502 are not engaged with the face gear 501, after the connecting arm 602 continues to move, the return spring in the assisting component 608 will quickly assist the connecting arm 602 to move, realizing the quick switching of the two driven gears 502 to the engaged state with the face gear 501, and avoiding the occurrence of the situation where the switching of the engaged state between the two driven gears 502 and the face gear 501 is not smooth.
