Description

Technical Field

[0001] The present invention relates to the technical field of thermal power generation, and specifically to a thermal power generation device and method using solar energy. Background Art

[0002] A thermal power plant is a factory that uses coal, petroleum, or natural gas as fuel to produce electric energy. Its basic production process is as follows: The fuel burns in the boiler to heat water into steam, converting the chemical energy of the fuel into heat energy. The steam pressure drives the steam turbine to rotate, converting heat energy into mechanical energy. Then the steam turbine drives the generator to rotate, converting mechanical energy into electric energy.

[0003] Since the principle of thermal power generation is to grind coal into pulverized coal and then inject the pulverized coal into the boiler for combustion, water evaporates into steam after being heated in the boiler, and is further heated by the superheater to become superheated steam with a specified pressure and temperature. Then it is sent into the steam turbine through a pipeline, and the steam turbine starts to drive the generator to rotate and generate electricity under the action of the steam. If cold water is directly injected into the boiler for heating, more coal will be consumed. The solar water heater can heat water to over ninety degrees under the sun's irradiation. Injecting the water heated by the solar water heater into the boiler can play a role in saving coal consumption.

[0004] However, if cold water is directly injected after the existing solar water heater heats the water, it is very easy to cause the collector tube to rupture. At the same time, since coal is ground into pulverized coal when burning the boiler, the content of pulverized coal in the air in the thermal power plant is relatively large, which will adhere to the surface of the collector tube, resulting in waste of pulverized coal and affecting the heating effect of the collector tube.

[0005] Based on this, the present invention designs a thermal power generation device and method using solar energy to solve the above problems. Summary of the Invention

[0014] A method for thermal power generation using solar energy, the specific steps of which are as follows:

[0015] Step 1: When the sun shines on the heating mechanism, the heating mechanism heats the water in the heating barrel by absorbing the heat of the sun.

[0016] Step 2: After the water in the heating barrel is heated, start the water changing mechanism to inject the hot water in the heating barrel into the boiler, and at the same time suck the cold water in the water storage tank into the heating barrel;

[0017] Step 3: While the water changing mechanism is changing water, the rotating mechanism drives the heating mechanism to disengage from the heating barrel. After the water changing mechanism finishes changing water, the rotating mechanism drives the heating mechanism to be docked with the heating barrel again;

[0018] Step 4: After the rotating mechanism drives the heating mechanism to disengage from the heating barrel, the cleaning and recycling mechanism replaces the heated and cooled heating mechanism with the heating mechanism that has just disengaged from the heating barrel, and then cleans and recycles the coal powder on the surface of the replaced heating mechanism.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. After the water in the heating barrel is heated by the heating mechanism of the present invention, then start the water changing mechanism. Through the water changing mechanism, the hot water in the heating barrel can be injected into the boiler, and at the same time the cold water in the water storage tank can be sucked into the heating barrel; while the water changing mechanism is changing water, drive the rotating mechanism. The rotating mechanism will drive the heating mechanism docked with the heating barrel to rotate downward and separate from the heating barrel. When the heating mechanism is separated from the heating barrel, the cold water in the heating barrel will not affect the relatively high-temperature heating mechanism, thus playing a role in protecting the heating mechanism; when the rotating mechanism replaces the heating mechanism docked with the heating barrel, at this time the cleaning and recycling mechanism starts to drive another cooled and cleaned heating mechanism to replace the heating mechanism that needs to be cleaned and cooled, and then through the cleaning and cooling mechanism, the coal powder on the surface of the replaced heating mechanism can be cleaned and recycled and the heating mechanism can be cooled; when the water changing mechanism finishes changing water, the rotating mechanism can drive the cooled heating mechanism to be docked with the heating barrel. Since the temperature of the heating mechanism is relatively low at this time, it will not break when contacting the cold water in the heating barrel; the device is simple to operate and convenient to use. When changing water, it can effectively avoid the damage of cold water to the heating mechanism, and at the same time can automatically clean and recycle the coal powder on the surface of the heating mechanism. While improving the solar energy utilization rate, it can effectively reduce the loss of coal powder.

[0021] 2. When water needs to be changed in the heating barrel in the present invention, the first motor is started at this time. The first motor drives the first threaded rod and the first bevel gear to rotate. The first bevel gear drives the third bevel gear to rotate through the second bevel gear. The third bevel gear drives the second rotating disk to rotate. When the second rotating disk rotates, it drives the cam to push the first push rod to the left. The first push rod drives the second push rod to move to the left through the first spring and the telescopic rod. The second push rod drives the first fixture block on its surface to move to a position where it is stuck with the second fixture block. When the first fixture block moves to a position where it is stuck with the second fixture block, at this time, the second rotating disk drives the first rotating disk to rotate. The first rotating disk drives the rotating mechanism to operate. Through the rotating mechanism, the fixing plate starts to rotate downward. When the fixing plate rotates downward, the second fixture block on its surface disengages from the third push rod. After the second fixture block disengages from the third push rod, it is stuck with the first fixture block under the action of the second spring, so that the second push rod can be maintained in a state where the sealing mechanism is kept closed. At this time, when the heat pipe is separated from the heating barrel, the water in the heat collecting pipe and the heating barrel will not flow out. Similarly, when the fixing plate resets to drive the heat collecting pipe to be butted with the heating barrel, at this time, the third push rod pushes the second fixture block away, and then under the action of the third spring, the sealing mechanism opens. Thus, it can be ensured that when the heat collecting pipe is separated from the heating barrel, water leakage from the heat collecting pipe and the heating barrel is prevented.

Detailed implementation manners

[0039] Please refer to Figures 1-15, the present invention provides a technical solution: a thermal power generation device and method using solar energy, including a bottom plate 1, on the upper surface of the bottom plate 1, a boiler 2 and a water storage tank 3 are fixedly connected. At the upper side position of the water storage tank 3, a heating barrel 4 is fixedly connected. On the left and right side surfaces of the heating barrel 4, a first water pipe 5 and a second water pipe 6 are respectively fixedly connected and communicated. The first water pipe 5 is fixedly connected and communicated with the boiler 2, and the bottom end of the second water pipe 6 is located at the bottom position of the water storage tank 3; there are two heating mechanisms at the front side position of the heating barrel 4, and one of the heating mechanisms is in contact with the surface of the heating barrel. The heating mechanism is used to heat the cold water in the heating barrel; a water changing mechanism is provided at the upper side position of the water storage tank 3. The water changing mechanism is used to inject the heated hot water into the boiler 2 and pump the cold water in the water storage tank 3 into the heating barrel after the heating mechanism heats the cold water in the heating barrel; a rotating mechanism is provided on the surface of the bottom plate 1. The rotating mechanism is used to drive the heating mechanism to rotate downward and separate from the heating barrel when the water changing mechanism changes water, and drive the heating mechanism to dock with the heating barrel upward after the water changing mechanism finishes changing water; a cleaning and recycling mechanism is provided on the upper surface of the bottom plate 1. The cleaning and recycling mechanism is used to replace the position of the cooled and cleaned heating mechanism with the heating mechanism that needs to be cleaned and cooled when the rotating mechanism replaces the heating mechanism on the surface of the heating barrel, and at the same time clean and recycle the pulverized coal on the surface of the replaced heating mechanism.

[0040] During operation, since the principle of thermal power generation is to grind coal into pulverized coal and then inject the pulverized coal into the boiler 2 for combustion, water is evaporated into steam after being heated in the boiler 2, further heated by the superheater to become superheated steam with a specified pressure and temperature, and then sent into the steam turbine through a pipeline. The steam turbine starts to drive the generator to rotate and generate electricity under the action of the steam. If cold water is directly injected into the boiler 2 for heating, more coal will be consumed. The solar water heater will heat the water to over ninety degrees under the sun's irradiation. Injecting the heated water into the boiler 2 through the solar water heater can play a role in saving coal consumption. However, if cold water is directly injected after the existing solar water heater heats the water, it is very easy to cause the rupture of the heat collecting tube 8. At the same time, since coal is ground into pulverized coal when burning the boiler 2, the content of pulverized coal in the air in the thermal power plant is relatively large, which will adhere to the surface of the heat collecting tube 8, resulting in waste of pulverized coal and affecting the heating effect of the heat collecting tube 8. After the water in the heating barrel 4 is heated by the heating mechanism of the device, the water changing mechanism is started. Through the water changing mechanism, the hot water in the heating barrel 4 can be injected into the boiler 2, and at the same time, the cold water in the water storage tank 3 is sucked into the heating barrel 4. While the water changing mechanism is changing water, the rotating mechanism is driven. The rotating mechanism will drive the heating mechanism connected to the heating barrel 4 to rotate downward and separate from the heating barrel 4. When the heating mechanism is separated from the heating barrel 4, the cold water in the heating barrel 4 will not affect the relatively high-temperature heating mechanism, thus playing a role in protecting the heating mechanism. When the rotating mechanism replaces the heating mechanism connected to the heating barrel 4, the cleaning and recycling mechanism starts to drive another cooled and cleaned heating mechanism to replace the heating mechanism that needs to be cleaned and cooled. Then, through the cleaning and cooling mechanism, the pulverized coal on the surface of the replaced heating mechanism can be cleaned and recycled, and the heating mechanism can be cooled. When the water changing mechanism finishes changing water, the rotating mechanism can drive the cooled heating mechanism to be connected to the heating barrel 4. Since the temperature of the heating mechanism is relatively low at this time, it will not rupture when contacting the cold water in the heating barrel 4. The device is simple to operate and convenient to use. When changing water, it can effectively avoid the damage of cold water to the heating mechanism, and at the same time, it can automatically clean and recycle the pulverized coal on the surface of the heating mechanism. While improving the utilization rate of solar energy, it can effectively reduce the loss of pulverized coal.

[0041] As a further solution of the present invention, the heating mechanism includes a fixing plate 7, and seven heat collecting tubes 8 are uniformly and fixedly connected to the surface of the fixing plate 7. The rear end of the heat collecting tube 8 is hermetically attached to the surface of the heating barrel 4; a sealing mechanism is provided at the positions where the inside of the heat collecting tube 8 and the inside of the heating barrel 4 are butt-jointed. The sealing mechanism is used to seal the heat collecting tube 8 and the heating barrel 4 before the heat collecting tube 8 is separated from the heating barrel 4 and to open the heat collecting tube 8 and the heating barrel after the heat collecting tube 8 is docked with the heating barrel; a driving mechanism is provided on the surface of the fixing plate 7, and the driving mechanism is used to drive the sealing mechanism to operate; during operation, when the sun shines on the surfaces of the seven heat collecting tubes 8, the heat collecting tubes 8 can gradually heat the water inside them, and the hot water in the heat collecting tubes 8 can gradually heat the water in the heating barrel 4; when it is necessary to replace the water in the heating barrel 4, at this time, the rotating mechanism will drive all the heat collecting tubes 8 to be separated from the heating barrel 4 at the same time. Before the heat collecting tube 8 is separated from the heating barrel 4, the driving mechanism will drive the sealing mechanism to operate. At this time, the sealing mechanism seals both the heat collecting tube 8 and the heating barrel 4, so as to prevent the water in the heat collecting tube 8 and the heating barrel 4 from flowing out; after the water in the heating barrel 4 is replaced, the rotating mechanism will drive the heat collecting tube 8 to be docked with the heating barrel 4. After the heat collecting tube 8 is docked with the heating barrel 4, the driving mechanism will drive the sealing mechanism to open, and at this time, the water in the heat collecting tube 8 and the heating barrel 4 will resume circulation.

[0042] As a further solution of the present invention, the driving mechanism includes a first rotating disk 9 and a second rotating disk 10. The first rotating disk 9 is rotatably connected to the water storage tank 3, and the second rotating disk 10 is rotatably connected to the first rotating disk 9. The second rotating disk 10 is located above the first rotating disk 9, and the rotation axes of the second rotating disk 10 and the first rotating disk 9 are on the same straight line. Two push blocks 11 are fixedly connected to the upper surface of the first rotating disk 9 and the lower surface of the second rotating disk 10. The two push blocks 11 on the surfaces of the first rotating disk 9 and the second rotating disk 10 are both distributed in a circumferential array. A cam 12 is fixedly connected to the surface of the second rotating disk 10. A first push rod 13 is provided at the left side of the cam 12. A telescopic rod 14 is fixedly connected to the left surface of the first push rod 13. A first spring 15 is arranged inside the telescopic rod 14, and the left end of the telescopic rod 14 is fixedly connected to a second push rod 16. The second push rod 16 is slidably connected to the fixed plate 7. A first clamping block 17 is fixedly connected to the surface of the second push rod 16, and a second clamping block 18 is slidably connected to the surface of the fixed plate 7. A second spring 19 is fixedly connected to the surface of the second clamping block 18, and the other end of the second spring 19 is fixedly connected to the fixed plate 7. The second clamping block 18 is in clamping cooperation with the first clamping block 17. A third push rod 20 is fixedly connected to the surface of the water storage tank 3, and the front surface of the third push rod 20 is in contact with the surface of the second clamping block 18. During operation, when the second rotating disk 10 rotates, the cam 12 and the two push blocks 11 on its surface will be driven to rotate. When the cam 12 rotates, it will push the first push rod 13 to the left. When the first push rod 13 moves to the left, it will drive the second push rod 16 to move to the left through the telescopic rod 14 and the first spring 15. When the first clamping block 17 on the surface of the second push rod 16 moves to the position where it is stuck with the second clamping block 18, since the third push rod 20 holds the second clamping block 18, the second clamping block 18 cannot be stuck with the first clamping block 17. At the same time, the push block 11 on the surface of the second rotating disk 10 rotates to the position where it contacts the push block 11 on the surface of the first rotating disk 9. At this time, the second rotating disk 10 will drive the first rotating disk 9 to rotate, and the first rotating disk 9 will drive the rotating mechanism to start running. At this time, the cam 12 on the surface of the second rotating disk 10 continues to rotate and pushes the first push rod 13 to continue moving to the left. At this time, the first push rod 13 starts to compress the telescopic rod 14. Under the action of the rotating mechanism, the fixed plate 7 starts to gradually rotate downward, and the second clamping block 18 on the surface of the fixed plate 7 will gradually disengage from the third push rod 20. When the second clamping block 18 disengages from the third push rod 20, under the action of the second spring 19, the second clamping block 18 starts to slowly be stuck with the first clamping block 17. After the second clamping block 18 is stuck with the first clamping block 17, the cam 12 will start to rotate to the position where it disengages from the first push rod 13.Similarly, when the second rotating disk 10 rotates in the reverse direction, it will drive the rotating mechanism to drive the fixing plate 7 to rotate upward. When the fixing plate 7 rotates upward to the original position, at this time, the cam 12 is in the original position and will not contact the first push rod 13; under the action of the fixing plate 7, the heat collecting tube 8 is completely butted with the heating barrel 4, and at the same time, under the action of the third push rod 20, the second clamping block 18 will be pushed forward to disengage from the first clamping block 17.;

[0043] As a further solution of the present invention, the sealing mechanism includes seven fourth push rods 21, and the seven fourth push rods 21 are respectively located at the bottom positions of the seven heat collecting tubes 8 and the seven fourth push rods 21 are all slidably connected to the fixing plate 7; on the front and rear sides of the surface of the fixing plate 7, a first connecting rod 22 and a second connecting rod 23 are respectively provided, and both the first connecting rod 22 and the second connecting rod 23 are fixedly connected to the seven fourth push rods 21 at the same time; a third spring 24 is fixedly connected to the surface of the first connecting rod 22, and the other end of the third spring 24 is fixedly connected to the fixing plate 7 and the elastic force of the third spring 24 is less than the elasticity of the first spring 15; an inclined plate 25 is fixedly connected to the upper side surface of the second connecting rod 23; the second push rod 16 is attached to the surface of the inclined plate 25; two sealing plates 26 are provided inside the heat collecting tube 8 and at the position where the heating tube is butted with the heat collecting tube 8, and the front and rear sealing plates 26 are respectively rotatably connected to the heat collecting tube 8 and the heating barrel 4; a first gear 27 is fixedly connected to the bottom end of the sealing plate 26, and the front and rear first gears 27 mesh with each other; a sliding frame 28 is fixedly connected to the bottom end of the first gear 27 at the front side position, and a sliding block 29 is slidably connected inside the sliding frame 28; the fourth push rod 21 is rotatably connected to the sliding blocks 29 on both the left and right sides at the same time; first one-way valves 30 are fixedly connected to the surfaces of the front and rear sealing plates 26, the flow direction of the first one-way valve 30 at the front side is forward and the flow direction of the first one-way valve 30 at the rear side is backward; during operation, when the water changing mechanism operates, the second push rod 16 will be driven to move leftward at this time. When the second push rod 16 moves leftward, it will drive the second connecting rod 23 to move backward under the action of the inclined plate 25. The second connecting rod 23 will drive all the fourth push rods 21 and the first connecting rod 22 to move backward. When the fourth push rod 21 moves backward, it will drive the sliding blocks 29 on both the left and right sides to rotate at the same time. The sliding blocks 29 can drive the two first gears 27 at the front side position to rotate at the same time through the sliding frame 28, and the first gear 27 at the front side will drive the first gear 27 at the rear side to rotate; under the action of the left and right gears, the two sealing plates 26 inside the heat collecting tube 8 and inside the heating barrel 4 are closed at the same time. When closing, the water between the front and rear sealing plates 26 can be discharged through the first one-way valve 30.
