Technical Field
[0001] The present invention relates to the technical field of thermal energy power engineering, and in particular to a waste heat recovery type thermal energy driving device and its application in power engineering. Background Art
[0002] The waste heat recovery thermal energy drive device is a highly efficient energy-saving equipment that utilizes the waste heat generated in the industrial production process and converts it into steam, electricity or other forms of useful energy through heat exchange and other means, effectively improving energy utilization efficiency and reducing production costs.
[0003] The Chinese invention patent with application number 201110079413.X proposes a compressor driven by thermal energy, including a compressor body and a turbine for driving the compressor. The turbine is connected to a power device based on an organic Rankine cycle, which includes an evaporator, a turbine, a condenser and a circulating pump. These four components are connected in sequence to form a loop through pipelines, and the circulating working fluid circulates in the loop. When the power device is working, the circulating working fluid flows through the evaporator, absorbs heat from an external heat source, and vaporizes into high-pressure steam. The high-pressure steam expands and works in the turbine, and the output work is transferred to the compressor. When the power output of the power device is not enough to meet the cooling and heating needs, electricity can be used to drive the compressor.

DETAILED DESCRIPTION
[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0037] In order to solve the problem that when the boiler heats the water, the impurities in the water will form crystals and float on the water surface. If not handled in time, the impurities will form crystals and adsorb on the inner wall of the boiler, affecting the thermal conductivity of the boiler and the need to adjust the driving speed of the driving device according to actual production and use conditions, embodiment 1 is proposed.
[0038] Embodiment 1:
[0039] like Figures 1 to 9As shown, the present invention provides a waste heat recovery type heat energy driving device, including a transmission shaft 8, on which are arranged in sequence a suction machine 1, a pressure reducing component 2, and a power component 3, the suction machine 1 is arranged at the end of the transmission shaft 8, and the end of the transmission shaft 8 away from the suction machine 1 is connected to an external mechanical device, the input end of the suction machine 1 is connected to an exhaust pipe 9, on which an adjusting component 7 is arranged, and the end of the exhaust pipe 9 away from the suction machine 1 is connected to a boiler component 4, a filter component 6 is arranged on the side of the boiler component 4, a cleaning component 5 is arranged on the boiler component 4, and a connecting pipe 10 is connected between the cleaning component 5 and the power component 3, and the connecting pipe 10 is used to discharge water vapor in the power component 3.
[0040] By setting the pressure reducing component 2, the water vapor generated in the boiler is decompressed and cooled, and then the water vapor is input into the power component 3 to drive the transmission shaft 8 to rotate, thereby driving the external mechanical equipment to operate; by setting the regulating component 7, the flow rate of the water vapor input into the power component 3 is adjusted to ensure that the rotation speed of the transmission shaft 8 is constant; by setting the cleaning component 5, the impurities generated on the water surface inside the boiler component 4 are scraped off to prevent the impurities from crystallizing and adhering to the inner wall of the boiler component 4 to affect the thermal conductivity of the boiler.
[0041] When realizing thermal energy drive, there are many kinds of heat sources that can be selected. In this embodiment, a boiler is used as a heat source as an example. When the boiler is generating heat, the water in the boiler will evaporate to form water vapor, and then the heat energy will be processed as kinetic energy and transferred to the power mechanism to do work, thereby converting the heat energy into kinetic energy. However, when the boiler heats the water, impurities in the water will form crystals floating on the water surface. If not processed in time, the impurities will form crystals and be adsorbed on the inner wall of the boiler, affecting the thermal conductivity of the boiler, thereby affecting the heating of the water.
[0042] In order to solve the above technical problems, Figure 3As shown, by setting a cleaning component 5, the impurities floating on the water surface are cleaned in time. The cleaning component 5 includes a rotating shaft 503. The rotating shaft 503 passes through the top plate of the boiler body 401 and extends into the interior of the boiler body 401. The top of the rotating shaft 503 is evenly provided with rotating blades 504, and the bottom of the rotating shaft 503 is evenly provided with a toggle plate 505. The toggle plate 505 is provided with a water level sensor for detecting water consumption and timely feeding back to the central control console. The central control console controls the external water supply component to supply water through the water supply pipe 407 in time. The toggle plate 505 contacts the liquid surface in the boiler component 4, and the end of the toggle plate 505 contacts the inner wall of the boiler body 401. The top surface of the toggle plate 505 is higher than the annular groove 402. The bottom surface is arranged to facilitate the removal of impurities on the water surface from the boiler body 401, and the lower half of the shifting plate 505 is below the liquid surface; the cleaning component 5 also includes a driving chamber 501, and the rotating shaft 503 is rotatably arranged on the central axis of the driving chamber 501, and an air inlet 502 is arranged on the side of the driving chamber 501, and the end of the connecting pipe 10 is arranged in the air inlet 502, and the position of the air inlet 502 is aligned with the center of the rotating blade 504. The water vapor in the power component 3 is discharged from the connecting pipe 10 and input into the driving chamber 501, and the water vapor drives the rotating blade 504 to rotate. An exhaust pipe 506 is arranged on the driving chamber 501, and a blocking valve is arranged in the exhaust pipe 506. Under normal conditions, the blocking valve is in an open state.
[0043] When in use, water vapor drives the rotating blades 504 to rotate, and the rotating blades 504 drive the rotating shaft 503 to rotate, thereby driving the shifting plate 505 to rotate, and the shifting plate 505 shifts the impurities on the water surface, so that the impurities are shifted to the filter plate 602 through the annular groove 402.
[0044] When water is boiling, bubbles will form at the bottom of the boiler body 401, and then float from the bottom to the water surface and burst. The gas in the bubbles is water vapor. During the rotation of the toggle plate 505, the bubbles that are about to burst near the water surface can be broken, thereby accelerating the output of water vapor and ensuring the stability of the water vapor output. The water vapor in the boiler body 401 is extracted by the suction machine 1 through the exhaust pipe 9.
[0045] The power assembly 3 and the cleaning assembly 5 are connected by setting a connecting pipe 10, and the rotating blades 504 and the toggle plate 505 are arranged in cooperation. The water vapor in the power assembly 3 is input into the cleaning assembly 5 through the connecting pipe 10 and can drive the rotating blades 504 to rotate, thereby driving the toggle plate 505 to rotate through the rotating shaft 503, and removing the impurities floating on the water surface to prevent the impurities from adhering to form crystals and affecting the thermal conductivity of the boiler assembly 4. At the same time, it can also accelerate the bursting of bubbles and accelerate the output of water vapor.
[0046] Since the transmission shaft 8 is connected to an external generator, the speed needs to be adjusted according to actual usage, so the rotation speed of the transmission shaft 8 needs to be adjusted. Therefore, in the present invention, corresponding components need to be set to regulate the output of water vapor, so as to adjust the rotation speed of the transmission shaft 8 through the power component 3.
[0047] In order to solve the above technical problems, Figure 4 As shown, in this embodiment, the flow rate of water vapor is controlled by setting an adjustment component 7, so as to change the amount of water vapor entering the power component 3. The adjustment component 7 includes a blocking block 707, the top of the blocking block 707 is connected to a lifting column 704, the top of the lifting column 704 is connected to a permanent magnet 705, and an electromagnet 703 is arranged on the outer side of the lifting column 704; after the electromagnet 703 is energized, a magnetic attraction force is generated on the permanent magnet 705, driving the permanent magnet 705 to descend, and a through hole is opened on the central axis of the electromagnet 703. The regulating assembly 7 further comprises a flow control chamber 701, a sealing block 707 being located inside the flow control chamber 701, a support frame 702 being disposed on the top of the flow control chamber 701, an electromagnet 703 being fixedly disposed on the support frame 702, a return spring 706 being disposed on the outer side of the portion of the lifting column 704 extending out of the top surface of the electromagnet 703, one end of the return spring 706 being fixedly disposed on the permanent magnet 705, and the other end of the return spring 706 being fixedly disposed on the electromagnet 703.
[0048] During use, when the speed of the transmission shaft 8 needs to be adjusted, the electromagnet 703 is controlled to be energized, generating a magnetic attraction force on the permanent magnet 705, attracting the permanent magnet 705 to descend and approach the electromagnet 703, the reset spring 706 is compressed, and the permanent magnet 705 drives the lifting column 704 to descend in the through hole of the electromagnet 703, thereby driving the blocking block 707 to descend and move to the pipe mouth of the exhaust pipe 9, reducing the space through which water vapor can pass, thereby changing the flow rate of water vapor.
[0049] When there is no need to adjust the speed of the transmission shaft 8, the control electromagnet 703 is powered off, the magnetic attraction force on the permanent magnet 705 disappears, and with the support of the elastic force of the reset spring 706, the permanent magnet 705 rises away from the electromagnet 703 and returns to its original position. The blocking block 707 leaves the pipe mouth of the exhaust pipe 9, and the water vapor flow rate returns to the original flow rate.
[0050] By setting the electromagnet 703, the permanent magnet 705 and the blocking block 707, according to the actual requirements, by controlling the power supply of the electromagnet 703, a magnetic attraction force is generated on the permanent magnet 705, so that the blocking block 707 is driven to rise and fall through the lifting column 704, thereby changing the space through which water vapor can pass in the exhaust pipe 9, thereby adjusting the flow rate of water vapor, adjusting the amount of water vapor entering the power component 3, and achieving the purpose of changing the rotation speed of the transmission shaft 8.
[0051] It should be noted that before the formal heat energy conversion is carried out, the step-down component 2 and the power component 3 are preheated to ensure that the temperature of the above two components is maintained within a certain energy range to prevent water vapor from condensing in a low temperature environment and affecting the power output of the water vapor.
[0052] Since the temperature of the water vapor is relatively high when it is discharged from the boiler, it is necessary to reduce the pressure and temperature of the water vapor before it is input into the power assembly 3 to prevent the internal structure of the power assembly 3 from being damaged due to excessive temperature, thereby affecting the power output.
[0053] In order to solve the above technical problems, Figure 5-Figure 8 As shown, in this embodiment, the water vapor is cooled by reducing the pressure layer by layer, and the water vapor generated in the boiler is reduced in pressure once and twice by setting a pressure reducing component 2. The pressure reducing component 2 includes a high-pressure chamber 201 and a medium-pressure chamber 203. An output pipe 207 is provided on the top of the medium-pressure chamber 203. The end of the output pipe 207 away from the medium-pressure chamber 203 is connected to the power component 3. An initial pressure reducing disk 202 is provided in the high-pressure chamber 201, and a secondary pressure reducing disk 204 is provided in the medium-pressure chamber 203. A support box 205 is provided on the side of the medium-pressure chamber 203 away from the high-pressure chamber 201, and a protective box 206 is provided on the side of the support box 205 away from the medium-pressure chamber 203.
[0054] The power assembly 3 includes a transmission chamber 301, and conical cylinders 302 are symmetrically arranged at both ends of the transmission chamber 301. When the temperature remains unchanged, reducing the pressure of water vapor will cause its volume to increase, because at a lower pressure, the distance between gas molecules will be relatively increased, thereby occupying a larger space. The setting of the conical cylinder 302 is convenient for adapting to the expansion of the volume of water vapor after the pressure is reduced. A stator and a rotor are arranged in the conical cylinder 302. The stator is used to accelerate the flow rate of water vapor, and the rotor is used to drive the transmission shaft 8 to rotate. The stator and the rotor are alternately arranged, and the diameter gradually increases along the inner side of the conical cylinder 302; the stator includes a rotating ring 303 and movable leaves 304, and the rotating ring 303 is fixedly set on the transmission shaft 8, and movable leaves 304 are evenly arranged on the radial direction of the rotating ring 303; water vapor is output from the transmission chamber 301 to the conical cylinders 302 on both sides. When passing through the rotor, it will drive the rotor to rotate, and at the same time its transmission speed and pressure will also be reduced. The water vapor passing through the rotor passes between the stators, the speed will increase again, and the pressure will continue to decrease. The rotor includes a fixed ring 305, fixed leaves 307 and a transfer plate 306. The fixed ring 305 is rotatably set on the transmission shaft 8, and the transfer plates 306 and fixed leaves 307 are evenly arranged on the radial direction of the fixed ring 305. The fixed leaves 307 are fixedly set on the inner wall of the conical cylinder 302.
[0055] like Figure 5 and Figure 8As shown, a recovery chamber 310 is provided on the conical cylinder 302, and a fixing frame 309 is provided on the outside of the recovery chamber 310. One end of the conical cylinder 302 away from the transmission chamber 301 extends into the interior of the recovery chamber 310. A buffer cylinder 308 is also provided in the recovery chamber 310. The buffer cylinder 308 is set to be conical, and one end is fixedly connected to the fixing ring 305 of the stator with the largest diameter, and the other end is fixedly connected to the side of the recovery chamber 310. A liquid outlet pipe 311 and a connecting pipe 10 are provided on the side of the recovery chamber 310. After the water vapor is decompressed, if the temperature in the recovery chamber 310 just reaches the condensation temperature, the water vapor will form liquid water and gather at the bottom of the recovery chamber 310. The liquid outlet pipe 311 is used to discharge the water at the bottom of the recovery chamber 310, and the connecting pipe 10 is used to recover the water vapor that enters the recovery chamber 310 after passing through the stator and rotor, and transport it to the driving chamber 501.
[0056] When in use, water vapor is inputted into the high pressure chamber 201 from the output end of the suction machine 1, and enters the medium pressure chamber 203 after being decompressed once by the initial decompression disk 202, and then inputted into the transmission chamber 301 from the output pipe 207 after being decompressed twice by the secondary decompression disk 204, and then inputted into the conical cylinder 302 on both sides, and the water vapor passes through the rotor stator in sequence, and in this process, the pressure of the water vapor continues to decrease, and the transmission speed remains stable. Specifically, when the water vapor passes through the rotor, it passes between the movable leaves 304, and the water vapor will drive the movable leaves 304 to rotate, and at the same time, its transmission speed and pressure will also decrease, and when the water vapor passes through the stator, it passes between the fixed leaves 307, and the transmission speed is increased again, and the pressure continues to decrease, and the volume of the water vapor increases due to the increase in the molecular distance, and is inputted into the recovery chamber 310 from the conical cylinder 302, and the water vapor entering the recovery chamber 310 is discharged from the connecting pipe 10, and is transported to the driving chamber 501 and drives the rotating blades 504 to rotate.
[0057] By setting up the pressure reducing component 2, the water vapor is decompressed and cooled to prevent the movable leaves 304 and the fixed leaves 307 from being damaged by excessive temperature when entering the recovery chamber 310. By setting up the movable leaves 304 and the fixed leaves 307, the transmission shaft 8 is driven to rotate by utilizing the transport of water vapor, thereby becoming a power source for driving the operation of external mechanical equipment and completing the purpose of converting thermal energy into kinetic energy.
[0058] like Fig. 9As shown, the boiler assembly 4 includes a boiler body 401, a side of the boiler body 401 is provided with an annular groove 402, the bottom surface of the boiler body 401 is evenly provided with supporting columns 405, the top surface of the boiler body 401 is provided with a liquid inlet 406, a water supply pipe 407 is provided in the liquid inlet 406, and an external water supply assembly is connected to the water supply pipe 407 to provide a water source for the boiler body 401; the filter assembly 6 includes a collecting box 601, the collecting box 601 is arranged on the outside of the annular groove 402, a filter plate 602 is arranged in the collecting box 601, a water branch pipe 603 is arranged on the side of the collecting box 601, the end of the water branch pipe 603 away from the collecting box 601 is fixedly arranged on the water supply pipe 407, and a water pump is arranged on the water branch pipe 603.
[0059] When in use, the rotating blades 504 push impurities on the water surface from the annular groove 402 to the filter plate 602, and the water falls into the bottom of the collection box 601. The water is then pumped out by a water pump and transported to the water supply pipe 407, and then enters the boiler body 401 again through the water supply pipe 407 for heating.
[0060] The working principle of the present invention is as follows: first, the suction machine 1 extracts water vapor from the boiler body 401, inputs it into the high-pressure chamber 201 through the exhaust pipe 9, and enters the medium-pressure chamber 203 after one decompression by the initial decompression disk 202. After a second decompression by the secondary decompression disk 204, it is input from the output pipe 207 into the transmission chamber 301, and then input into the conical cylinders 302 on both sides. The water vapor passes through the rotor and stator in turn. During this process, the pressure of the water vapor continues to decrease and the transmission speed remains stable. Specifically: when water vapor passes through the rotor, it passes between the movable leaves 304, and the water vapor will drive the movable leaves 304 to rotate. At the same time, its transfer speed and pressure will also decrease. When water vapor passes through the stator, it passes between the fixed leaves 307, and the transfer speed is increased again. The pressure continues to decrease, and the volume of the water vapor increases due to the increase in the molecular distance. It is input from the conical cylinder 302 into the recovery chamber 310. As the water vapor continues to enter the recovery chamber 310, the water vapor in the recovery chamber 310 is gradually discharged from the connecting pipe 10 and transported to the driving chamber 501.
[0061] Secondly, water vapor is continuously inputted from the connecting pipe 10 into the driving chamber 501, pushing the rotating blades 504 to rotate, and the rotating blades 504 drive the rotating shaft 503 to rotate, thereby driving the toggle plate 505 to rotate, and the toggle plate 505 to toggle the impurities on the water surface, so that the impurities are toggled to the filter plate 602 through the annular groove 402, and the water falls to the bottom of the collection box 601, and then the water is pumped out by the pump and transported to the water supply pipe 407, and then enters the boiler body 401 again along with the water supply pipe 407 for heating. When the water is boiling, bubbles will form at the bottom of the boiler body 401, and then float from the bottom to the water surface to burst. The gas in the bubbles is water vapor. During the rotation process, the toggle plate 505 can also break the bubbles that are about to burst near the water surface, thereby accelerating the output of water vapor.
[0062] Finally, when the speed of the transmission shaft 8 needs to be adjusted, the control electromagnet 703 is energized to generate magnetic attraction on the permanent magnet 705, attracting the permanent magnet 705 to descend close to the electromagnet 703, the reset spring 706 is compressed, and the permanent magnet 705 drives the lifting column 704 to descend in the through hole of the electromagnet 703, thereby driving the blocking block 707 to descend and move to the mouth of the exhaust pipe 9, reducing the space that water vapor can pass through, thereby changing the flow rate of water vapor. When the speed of the transmission shaft 8 does not need to be adjusted, the control electromagnet 703 is powered off, the magnetic attraction generated on the permanent magnet 705 disappears, and under the support of the elastic force of the reset spring 706, the permanent magnet 705 rises away from the electromagnet 703 and returns to its original position, the blocking block 707 leaves the mouth of the exhaust pipe 9, and the water vapor flow rate returns to the original flow rate.
[0063] Based on the technical solution of the above-mentioned embodiment 1, due to the continuous output of water vapor, the water level in the boiler body 401 drops. When water is input into the external water supply component, the input of cold water will cause the boiling liquid surface to be briefly still. During the still time, there is no water vapor output from the water surface, resulting in unstable water vapor output, which leads to the interruption of the subsequent water vapor input into the power component 3, thereby affecting the stability of the rotation of the transmission shaft 8. Therefore, embodiment 2 is proposed to solve the above-mentioned technical problems.
[0064] Embodiment 2:
[0065] Supplementary holes 403 are evenly opened on the top surface of the boiler body 401, and a closing plate 404 is rotatably arranged in the supplementary hole 403. Pressure sensors are respectively arranged in the boiler body 401 and the driving chamber 501 to detect the pressure changes of the gases inside the two. When the water vapor is continuously output, the pressure values in the boiler body 401 and the driving chamber 501 are respectively maintained in a relatively constant numerical range and recorded as the initial value.
[0066] When the pressure sensor detects that the pressure inside the boiler body 401 becomes smaller than the initial value, and the pressure in the driving chamber 501 increases relative to the initial value, it means that the current time is the static time after adding water. At this time, the replenishing hole 403 is opened to replenish the water vapor in the driving chamber 501 into the boiler body 401; when the pressure sensor detects that the pressure in the boiler body 401 returns to the initial value and gradually increases, it means that the water body has returned to the boiling state and continues to output water vapor. At this time, the replenishing hole 403 is closed to complete the replenishment of water vapor, so as to avoid the interruption of water vapor output affecting the stability of the subsequent rotation of the transmission shaft 8.
[0067] Specifically, when the water level sensor detects that the water level inside the boiler body 401 drops to the position where water needs to be added, the blocking valve in the exhaust pipe 506 is first controlled to be closed, and the central console controls the external water supply component to input water into the boiler body 401 through the water supply pipe 407. At this time, there is no water vapor output from the water surface, the suction machine 1 is still continuously sucking, and the connecting pipe 10 is also continuously inputting. The gas inside the boiler body 401 is extracted, and the pressure sensor detects that the pressure inside the boiler body 401 becomes smaller than the initial value, and the pressure inside the drive chamber 501 increases relative to the initial value. At this time, the closing plate 404 is controlled to rotate downward to open the replenishing hole 403, and the boiler body 401 and the drive chamber 501 are interconnected. The water vapor in the drive chamber 501 enters the boiler body 401 from the replenishing hole 403 to replenish the boiler body 401 with water vapor until the pressure sensor detects that the pressure inside the boiler body 401 returns to the initial value and begins to gradually increase, which means that the water in the boiler body 401 returns to a boiling state, bubbles begin to burst out of the liquid surface, and water vapor is continuously output. At this time, the closing plate 404 is controlled to rotate upward to close the replenishment hole 403, and the blocking valve in the exhaust pipe 506 is controlled to open. The water vapor replenishment during the static time of water addition in the boiler body 401 is completed to avoid interruption of water vapor output.
[0068] By setting a pressure sensor to detect the change in the pressure value inside the boiler body 401 and the driving chamber 501, the current water vapor deficiency state can be judged, thereby controlling the opening and closing of the replenishment hole 403 to complete the replenishment of water vapor, and avoid that when the external water supply component adds water to the boiler body 401, the boiling liquid surface becomes temporarily still and there is no water vapor output on the water surface, resulting in unstable water vapor output, thereby affecting the stability of the subsequent rotation of the transmission shaft 8.
