Description

Technical Field

[0001] This invention relates to the field of steam turbine power generation technology, specifically to an energy-saving steam turbine power generation waste heat recovery device. Background Technology

[0002] A steam turbine generator is a generator driven by a steam turbine. Superheated steam generated by a boiler enters the steam turbine, expands, and performs work, causing the blades to rotate and drive the generator to produce electricity. The exhaust steam after performing work is sent back to the boiler for recycling through a condenser, circulating water pump, condensate pump, and feedwater heating device. The high-temperature steam after the steam turbine generates electricity still contains a large amount of heat. Currently, most steam turbine generators on the market directly condense the high-temperature steam after power generation, resulting in a large amount of heat waste. At the same time, the waste heat after steam condensation is difficult to reuse, resulting in poor practicality. Furthermore, most existing waste heat reuse equipment can only utilize the waste heat alone and cannot utilize the residual pressure, reducing the functional versatility of the equipment. After the high-temperature steam is condensed, the condensate flows back into the preheating tank, causing excessive pressure inside the preheating tank and reducing the safety of its use. In addition, the pressure after the existing high-temperature steam is discharged is too low, making it difficult to drive the generator mechanism, thus reducing the practicality of the equipment.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention uses a preheating mechanism to divert high-temperature steam through a distribution pipe. The high-temperature steam then enters the coil to preheat the water at the top, center, and bottom of the preheating tank. The preheated water is then injected into the steam turbine. When the steam turbine generates electricity, there is no need to heat the water from zero, thus saving energy.

[0016] 2. By installing a pressure relief mechanism, the present invention utilizes a spring to press the valve, thereby achieving pressure relief while ensuring the internal pressure of the preheating tank, thus avoiding excessive internal pressure in the preheating tank and improving the safety of the preheating tank in use.

[0017] 3. Through the installation of the pressurizing mechanism, the diameters of the three rubber bladders in the pressurizing mechanism are distributed in a stepped manner, and the high-temperature steam flows from the large-diameter rubber bladder to the small-diameter rubber bladder, which increases the flow rate and pressure of the high-temperature steam and facilitates the increase of the driving force of the high-temperature steam on the power generation mechanism.

[0018] 4. This invention, through the installation of a residual pressure power generation mechanism, inputs pressurized and accelerated high-temperature steam into the spiral output of the spiral bend. Subsequently, the spiral airflow drives the spiral shaft to rotate, and then the spiral shaft drives the sprocket and chain to rotate, thereby driving the generator to rotate, realizing the power generation of steam airflow and improving the functional versatility of the equipment.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-12An embodiment of the present invention provides an energy-saving steam turbine power generation waste heat recovery device, comprising a base plate 1, two supporting steel pipes 2 symmetrically installed on both sides of the bottom of the base plate 1, and three supporting legs 10 installed at the center of the top of the base plate 1. A fixing ring 11 is installed on the top of the three supporting legs 10, and the inner circumference of the fixing ring 11 is fixedly connected to the bottom of the outer circumference of the generator box 12. The supporting steel pipes 2 serve to support the base plate 1, the supporting legs 10 are used to install the fixing ring 11, and the fixing ring 11 is used to fix the generator box 12, ensuring the stable installation of the generator box 12. A preheating tank 3 is installed on one side of the top of the base plate 1, and a pressure relief mechanism 5 is installed on one side of the top of the preheating tank 3. The pressure relief mechanism 5 includes a fixing sleeve 501, a central column 502, a central hole 503, a vent hole 504, and a top plate 50. 5. Spring 506, valve stem 507, connecting hole 508, and clamping hole 509. A fixing sleeve 501 is installed on one side of the top of the preheating tank 3. A connecting hole 508 is opened at the center of the bottom of the fixing sleeve 501, which communicates with the inside of the preheating tank 3. A clamping hole 509 is opened at the top of the connecting hole 508. A valve stem 507 is attached to the top of the clamping hole 509. A central column 502 is installed at the center of the top of the valve stem 507. A spring 506 is sleeved around the outer edge of the central column 502. The bottom of the spring 506 is fixedly connected to the center of the top of the valve stem 507. A top plate 505 is installed on the top of the fixing sleeve 501. A central hole 503 is opened at the center of the top of the top of the top plate 505. The central column 502 passes through the central hole 503. The top of the spring 506 is connected to the top plate 507. The bottom of plate 505 is fixedly connected, and vent holes 504 are evenly distributed around the top periphery of plate 505. When the internal pressure of preheating tank 3 is within the normal range, the elastic force of spring 506 tightly presses valve 507 and pressing hole 509 together to ensure the internal pressure of preheating tank 3. When the internal pressure of preheating tank 3 exceeds the normal range, the pressure pushes open valve 507 to release pressure, ensuring the normal internal pressure of preheating tank 3 and avoiding the situation of preheating tank 3 cracking due to excessive pressure. This helps to extend the service life of preheating tank 3. A preheating mechanism 4 is installed at the center of the top of preheating tank 3. The preheating mechanism 4 includes a return bend 401, coil 402, central tube 403, connecting tube 404, and diversion tube 405. The return bend 401 is installed at the center of the top of preheating tank 3. Furthermore, a central pipe 403 is installed at the bottom of the return bend 401. Coils 402 are installed at the top, center, and bottom of the central pipe 403, and the three coils 402 are internally connected to the central pipe 403. Three connecting pipes 404 are installed at one end of the central pipe 403, and one end of each connecting pipe 404 penetrates one side of the preheating tank 3. A diversion pipe 405 is installed at one end of each connecting pipe 404, and the diversion pipe 405 is internally connected to the three connecting pipes 404. One end of the diversion pipe 405 is fixedly connected to one side of the residual pressure power generation mechanism 6. The preheating mechanism 4 divides the high-temperature steam into three streams through the diversion pipe 405. The three streams of high-temperature steam enter the coils 402 respectively, and the coils 402 preheat the top, center, and bottom of the preheating tank 3 respectively. Compared with traditional heating equipment...Heating is applied to the top, center, and bottom separately, resulting in high heating efficiency. A residual pressure power generation mechanism 6 is installed on one side of the preheating mechanism 4. A power generation box 12 is installed at the bottom of the residual pressure power generation mechanism 6, and a connecting hose 13 is installed at the center of the bottom of the power generation box 12. A pressurizing mechanism 14 is installed at one end of the connecting hose 13. The pressurizing mechanism 14 includes a first fixed pipe 1401, a first rubber bladder 1402, a first elastic ring 1403, a second fixed pipe 1404, a second rubber bladder 1405, a second elastic ring 1406, a third fixed pipe 1407, a third rubber bladder 1408, a third elastic ring 1409, and a fourth fixed pipe 1410. A pressurizing box 9 is fixedly inserted through one end of the connecting hose 13, and the pressurizing box 9 is installed on one side of the top of the base plate 1. A fourth fixing tube 1410 is installed at the top, and a third rubber bladder 1408 is installed at the top of the fourth fixing tube 1410. Third elastic rings 1409 are evenly installed on the outer circumference of the third rubber bladder 1408, and a third fixing tube 1407 is installed at the top of the third rubber bladder 1408. A second rubber bladder 1405 is installed at the top of the third fixing tube 1407, and second elastic rings 1406 are evenly installed on the outer circumference of the second rubber bladder 1405. A second fixing tube 1404 is installed at the top of the second rubber bladder 1404, and a first rubber bladder 1402 is installed at the top of the second fixing tube 1404. First elastic rings 1403 are evenly installed on the outer circumference of the first rubber bladder 1402, and a first fixing tube 1401 is installed at the top of the first rubber bladder 1402. An air inlet pipe 7 is installed at the top of the first fixed pipe 1401, and one end of the air inlet pipe 7 penetrates the center of the top of the pressurization box 9. A fixed flange 8 is installed at one end of the air inlet pipe 7, which facilitates connecting the air inlet pipe 7 to the exhaust pipe of the steam turbine through the fixed flange 8, so as to facilitate the transportation of high-temperature and high-pressure steam discharged from the steam turbine into the air inlet pipe 7. The diameter of the first rubber bladder 1402 is 1.2 times the diameter of the second rubber bladder 1405, the diameter of the second rubber bladder 1405 is 1.2 times the diameter of the third rubber bladder 1408, the diameter of the first fixed pipe 1401 is 1.4 times the diameter of the second fixed pipe 1404, the diameter of the second fixed pipe 1404 is 1.4 times the diameter of the third fixed pipe 1407, and the first rubber bladder 1402, the second rubber bladder 1405, and the third rubber bladder 1407 are connected to the first fixed pipe 1402. The diameters of the three rubber bladders 1408 gradually decrease, so that the pressure and flow rate of the high-temperature steam gradually increase after passing through the first rubber bladder 1402, the second rubber bladder 1405, and the third rubber bladder 1408, thus pressurizing the high-temperature steam for subsequent use. A water outlet pipe 15 is installed at the bottom of one side of the preheating tank 3, and the water outlet pipe 15 is connected to the inside of the preheating tank 3. The installation of the preheating mechanism 4 preheats the clean water in the preheating tank 3 and delivers the preheated water to the steam turbine, eliminating the need to heat the clean water from zero, which helps to save energy. The pressurizing mechanism 14 pressurizes and accelerates the high-temperature steam, and uses the pressurized and accelerated steam to drive the residual pressure power generation mechanism 6. The residual pressure power generation mechanism 6 uses the pressurized high-temperature steam to generate electricity, improving the functional versatility of the equipment.The residual pressure power generation mechanism 6 includes a fixed box 601, a spiral shaft 602, a drive sprocket 603, a gas supply pipe 604, a spiral bend 605, a connecting block 606, an insulation layer 607, a mounting box 608, a threaded cavity 609, a first bearing block 610, a fixed block 611, a generator body 612, a chain 613, a driven sprocket 614, and a second bearing block 615. A gas supply pipe 604 is installed at one end of the diversion pipe 405, and a mounting box 608 is installed at the bottom of one end of the gas supply pipe 604. The gas supply pipe 604 communicates internally with the mounting box 608. Connecting blocks 606 are fitted onto the top and bottom of the outer circumference of the mounting box 608, and the outer circumferences of the two connecting blocks 606 are fixedly connected to the inner circumference of the generator box 12. An insulation layer 607, made of polyurethane, is fitted around the center of the outer circumference of the mounting box 606. When high-temperature steam flows through the mounting box 608, the polyurethane insulation layer 607 insulates the interior of the mounting box 608, reducing heat loss. A threaded cavity 609 is installed on the inner circumference of the mounting box 608, and a first bearing block 610 is installed at the bottom of the inner circumference of the mounting box 608. A spiral shaft 602 is rotatably connected to the top of the first bearing block 610, and the top of the spiral shaft 602 movably passes through the center of the top of the generator box 12. A fixed box 601 is fixedly connected to the top of the generator box 12. A second bearing block 615 is fitted around the spiral shaft 602, and the second bearing block 615 is rotatably connected to the spiral shaft 602. 5. Installed on one side of the bottom surface inside the fixed box 601, the mounting box 608 has a spiral bend 605 installed at the bottom, and the spiral bend 605 communicates with the inside of the mounting box 608. The bottom of the spiral bend 605 is fixedly connected to the top of the connecting hose 13. The inside of the threaded cavity 609 is spiral-shaped. After high-temperature steam flows in from the spiral bend 605, it rotates along the threaded cavity 609. The high-temperature steam still maintains a spiral upward shape, which facilitates the rotation of the spiral shaft 602. The connecting block 606 connects the mounting box 608 to the generator box 12, ensuring the stable installation of the mounting box 608 inside the generator box 12. The top of the spiral shaft 602 is equipped with a drive sprocket 603, and a chain 613 is meshed on the outer circumference of the drive sprocket 603. A driven sprocket 614 is circumferentially engaged within the chain 613. A generator body 612 is mounted on one side of the bottom of the fixed box 601, with its output end fixedly connected to the center of the bottom of the driven sprocket 614. A fixing block 611 is mounted on one side of the generator body 612, with one end of the fixing block 611 fixedly connected to the top of one side of the generator box 12. The rotation of the spiral shaft 602 drives the driving sprocket 603 to rotate, which in turn drives the chain 613 to rotate, subsequently driving the driven sprocket 614 to rotate, and ultimately driving the generator body 612 to rotate. This achieves power generation by converting the kinetic energy of the spiral steam into electrical energy, thus realizing steam power generation. This enhances the overall functionality of the equipment while saving energy.

[0034] Working Principle: In operation, the equipment is first moved to a designated location. The turbine's exhaust pipe is then fixedly connected to the fixed flange 8, allowing the high-temperature steam generated by the turbine to be transported to the intake pipe 7. The steam then enters the pressurization mechanism 14, passes through the first fixed pipe 1401, and enters the first rubber bladder 1402, which gradually expands. The high-temperature steam then enters the second fixed pipe 1404, followed by the second rubber bladder 1405, then the third fixed pipe 1407, and finally the third rubber bladder 1408, before exiting from the fourth fixed pipe 1410. The diameters of the first, second, and third rubber bladders 1402 and 1405 gradually decrease. As the volume of gas contained decreases, with the intake air volume remaining constant, high-temperature steam is pressurized inside the first rubber bladder 1402, the second rubber bladder 1405, and the third rubber bladder 1408 and then ejected. Simultaneously, the diameters of the first fixed tube 1401, the second fixed tube 1404, the third fixed tube 1407, and the fourth fixed tube 1410 gradually decrease, accelerating the gas flow rate. The first elastic ring 1403 increases the elasticity and structural strength of the first rubber bladder 1402, the second elastic ring 1406 increases the elasticity and structural strength of the second rubber bladder 1405, and the third elastic ring 1409 increases the elasticity and structural strength of the third rubber bladder 1408. Subsequently, the high-temperature steam enters the connecting hose 13 and then the spiral bend 605, flowing through the spiral... The bend in pipe 605 creates a spiral airflow, which enters the mounting box 608 and spirals upward in the threaded cavity 609. During this upward spiral, the airflow drives the spiral shaft 602 to rotate, which in turn drives the drive sprocket 603, which in turn drives the chain 613, which in turn drives the driven sprocket 614. The rotation of the driven sprocket 614 drives the input shaft of the generator body 612, thus generating electricity using the generator body 612. This steam-powered generation is beneficial for utilizing the pressure of the emitted high-temperature steam, enhancing the versatility of the equipment's functions. The high-temperature steam then enters the diversion pipe 405 through the gas delivery pipe 604, where it is diverted. The diverted high-temperature steam then enters the connecting... The water flows into pipe 404 and then into coil 402. Coil 402 preheats the water at the top, center, and bottom of preheating tank 3. The preheated and condensed water then flows through central pipe 403 into return bend 401 and then back into preheating tank 3, preheating the water at the top, center, and bottom of preheating tank 3 separately. This process is fast and efficient. Simultaneously, the pressure relief mechanism 5 is installed. When the pressure in preheating tank 3 is below the warning threshold, the spring force of spring 506 presses valve 507 tightly against the clamping hole 509, ensuring the seal of the fixing sleeve 501. When the pressure inside preheating tank 3 exceeds the threshold, the pressure pushes valve 507 upwards, opening the clamping connection between valve 507 and clamping hole 509.Subsequently, the gas inside the preheating tank 3 enters the fixed sleeve 501 through the connecting hole 508, and then exits through the vent hole 504, thereby achieving pressure relief inside the preheating tank 3. This prevents the preheating tank 3 from rupturing due to excessive internal pressure, thus extending the service life of the preheating tank 3. The central column 502 and the central hole 503 are used to maintain the movement direction of the valve 507. The top plate 505 is used to install the spring 506. The second bearing block 615 is used to fix the spiral shaft 602, the first bearing block 610 is used to fix the spiral shaft 602, the supporting steel pipe 2 is used to support the base plate 1, the supporting leg 10 is used to support the fixing ring 11, and the fixing ring 11 is used to fix the generator box 12.
