Description

Technical Field

[0001] The present invention relates to the technical field of thermal power generation devices, in particular to a high-efficiency energy-saving thermal power generation device and a power generation method. Background Art

[0002] The basic principle of thermal power generation is to generate a large amount of heat energy through the combustion of fuel (such as coal, natural gas, etc.). During the combustion process, the chemical energy of the fuel is converted into heat energy, and water vapor and exhaust gas are produced at the same time. The heat energy generated by the combustion is used to heat the water in the inner tank and convert it into steam. The saturated steam generated is sent to the steam turbine, and the expansion of the steam drives the rotation of the turbine, which in turn drives the generator to generate electricity.

[0003] A steam power generation device is proposed in the utility model patent with publication number CN221002879U. No filtering component is provided at the water inlet of the power generation device. Impurities in the water, such as dissolved oxygen, chloride ions, sulfate ions, etc., can react electrochemically with metals, leading to corrosion of metal components. Meanwhile, impurities such as mud, sand and microorganisms affect the corrosion of metal components through physical action, seriously affecting the safe and economical operation of the inner tank and shortening its service life. When the calcium and magnesium ion content in the water is high, after heating, these ions will combine with other components in the water to form water-insoluble substances, such as calcium carbonate and magnesium carbonate. These substances will precipitate and form scale during the heating process. The scale adheres to the inner tank and affects the heating effect. After adding water source, it takes time to heat the water in the inner tank, and the larger the amount of water, the longer it takes to heat to boiling. Therefore, when the water source is first heated, the heating efficiency is slow. Summary of the invention

When the internal water source needs to be discharged from the inner tank 801, the external water pipe is connected to the drain pipe 406. Before draining, the motor 504 can be started. When the output shaft of the motor 504 rotates, the mounting shaft 502 is driven to rotate. The mounting shaft 502 drives the scraper frame 503 to move. The scraper frame 503 scrapes off the scale adhering to the inner wall of the inner tank 801. The scale adhering to the inner wall of the inner tank 801 is scraped off by the scraper frame 503 to avoid the scale adhering to the inner wall of the inner tank 801 and affecting the heating effect.

At the same time, when the mounting shaft 502 rotates, it drives the first pulley 505 The first pulley 505 drives the second pulley 506 to rotate through the belt, and the second pulley 506 drives the connecting shaft 508 to rotate.

When it is necessary to clean the impurities filtered by the filter 303, the filtered impurities can be cleaned by removing the threaded cover 304.When the filter screen 303 needs to be removed, the hydraulic rod 605 is extended, and the telescopic end of the hydraulic rod 605 drives the connecting plate 606 to move upward. Since the drive shaft 601, the connecting box 301 and the installation frame 302 can slide and rotate, the connecting plate 606 drives the drive shaft 601 to move upward, so that the drive shaft 601 drives the plug-in block 602 to no longer engage with the rotating shaft 305. When the bottom surface of the plug-in block 602 moves to a position higher than the installation frame 302, the plug-in block 606 is 02 will not block the installation frame 302, and then the installation frame 302 can be removed from the connection box 301 to replace the filter 303.

When the plug-in block 602 is not aligned with the hole, the plug-in block 602 will shrink into the drive shaft 601, and the spring 603 will shrink. When it is rotated to align with the hole, it will be engaged with the rotating shaft 305 under the action of the spring 603.

[0038] Specifically, Figure 2 and Figure 3 As shown, the heating furnace 2 is provided with a cooling structure 7, and the cooling structure 7 includes a condenser 701 installed on the cylinder wall of the heating furnace 2 and a first pipe 702 installed on the condenser 701. A spiral pipe 703 is installed in the heating furnace 2, and the other end of the first pipe 702 is fixedly connected to the spiral pipe 703. A second pipe 704 is fixedly connected to the bottom of the condenser 701, and the other end of the second pipe 704 is fixedly connected to the spiral pipe 703. The first pipe 702 and the second pipe 704 are both connected to the spiral pipe 703. Tube 703 is connected, and the steam generated in the inner tank 801 enters the safety valve 803 through the delivery pipe 802, and then enters the output pipe 804, and finally enters the power exchange device 805 to convert electricity. At the same time, the condenser 701 can be started, and the coolant is added to the spiral tube 703 inside the heating furnace 2 through the first pipe 702, and then enters the condenser 701 from the second pipe 704, so that the coolant circulates and cools down the heating furnace 2, which can prevent certain injuries to the staff and avoid scalding the staff.

[0039] A power generation method of a high-efficiency energy-saving thermal power generation device comprises the following steps:

[0040] S1: First, water is added into the inner tank 801. When adding water, impurities in the water are filtered through the filtering structure 3. After the water is added, the water in the inner tank 801 is heated by the fuel at the bottom of the boiler 1. When the water is heated, the heating speed of the water in the inner tank 801 is accelerated through the circulation structure 4.

[0041] S2: The water vapor generated by the heated water generates electricity through the power generation structure 8, and the cylinder wall of the heating furnace 2 is cooled by the cooling structure 7 during the heating process;

[0042] S3: Before the waste water is discharged, the scale in the inner tank 801 can be scraped off by the scraping structure 5 , and the scraping structure 5 cooperates with the driving structure 6 to clean the filter components in the filter structure 3 during scraping.

[0043] When the present invention is used, firstly, the water pipe of the external water source is connected to the water inlet pipe 309, and then the water source enters the connection box 301 through the water inlet pipe 309, and then passes through the filter 303, and the water source enters the inner tank 801 from the first connecting pipe 307. Before the water source enters the first connecting pipe 307, the impurities in the water will be filtered by the filter 303. The impurities in the water are filtered by the filter 303, which prevents the impurities from entering the inner tank 801 and corroding the inner tank 801, thereby increasing the service life of the inner tank 801. After the water source is added to the inner tank 801, by adding fuel to the bottom of the boiler 1, Then, the inner tank 801 is heated by the fuel. During the heating, the circulation pump 402 is started. When the circulation pump 402 is started, the water source in the inner tank 801 enters the second hose 404 through the fixed pipe 405, then enters the first hose 403 from the circulation pump 402, and then enters the connection box 301, and then enters the inner tank 801 from the first connection pipe 307 on the connection box 301, so that the water in the inner tank 801 circulates. The water circulation strengthens the effect of heat convection, makes the heat absorption more uniform, and can accelerate the heating of the water source inside the inner tank 801, thereby improving the heat utilization rate and the heating efficiency of the water source.

[0044] The steam generated in the inner tank 801 enters the safety valve 803 through the delivery pipe 802, then enters the output pipe 804, and finally enters the power exchange device 805 to convert electricity. At the same time, the condenser 701 can be started, and the coolant is added to the spiral tube 703 inside the heating furnace 2 through the first pipe 702, and then enters the condenser 701 from the second pipe 704, so that the coolant circulates and cools down the heating furnace 2, which can prevent certain injuries to the staff and avoid scalding of the staff;

[0045] When it is necessary to discharge the internal water source from the inner tank 801, the external water pipe is connected to the drain pipe 406. Before draining, the motor 504 can be started. When the output shaft of the motor 504 rotates, the mounting shaft 502 is driven to rotate, and the mounting shaft 502 drives the scraper frame 503 to move. The scraper frame 503 will scrape off the scale adhering to the inner wall of the inner tank 801. The scraper frame 503 scrapes off the scale on the inner wall of the inner tank 801 to prevent the scale from adhering to the inner wall of the inner tank 801 and affecting the heating effect. When heating the water source, the scraper frame 503 can be rotated to stir the water source, and the contact between the liquid surface and the air is increased during the stirring of the water. area, thereby promoting the heat transfer process and improving the heating speed. At the same time, when the mounting shaft 502 rotates, it drives the first pulley 505 to rotate, the first pulley 505 drives the second pulley 506 to rotate through the belt, the second pulley 506 drives the connecting shaft 508 to rotate, the connecting shaft 508 drives the driving shaft 601 to rotate through the connecting rod 604, the driving shaft 601 drives the rotating shaft 305 to rotate through the plug-in block 602, the rotating shaft 305 drives the cleaning plate 306 to stir the impurities at the bottom of the filter 303, and avoids the impurities in the water source being concentrated at the filter 303 when adding water, which affects the water adding efficiency. When the inner wall of the inner tank 801 is cleaned, the water source is discharged from the drain pipe 406, and the cleaned scale will also flow out with the water source. When it is necessary to clean the impurities filtered by the filter 303, the threaded cover 304 is removed to clean the filtered impurities. When it is necessary to disassemble the filter 303, the hydraulic rod 605 is extended, and the telescopic end of the hydraulic rod 605 drives the connecting plate 606 to move upward. Since the drive shaft 601, the connecting box 301 and the installation frame 302 can all slide and rotate, the connecting plate 606 drives the drive shaft 601 to move upward, so that the drive shaft 601 The plug-in block 602 is driven to no longer engage with the rotating shaft 305. When the bottom surface of the plug-in block 602 moves to be higher than the installation frame 302, the plug-in block 602 will not cause any obstruction to the installation frame 302. Then the installation frame 302 can be removed from the connection box 301 to replace the filter 303. When the plug-in block 602 is engaged with the rotating shaft 305, it is only necessary to move the drive shaft 601 downward. When the plug-in block 602 is not aligned with the hole, the plug-in block 602 will shrink into the drive shaft 601, and the spring 603 will shrink. When it is rotated to be aligned with the hole, it will engage with the rotating shaft 305 under the action of the spring 603.
