Description

Technical Field

[0001] The invention relates to the technical field of steam-water supply for thermal power generation, and in particular to an intelligent steam-water supply device for thermal power generation. Background Art

[0002] Thermal power generation is a method of using the heat energy generated by the combustion of fossil fuels (such as coal, oil, natural gas, etc.) to heat water, turning the water into high-temperature, high-pressure steam, and then using the steam to drive the generator to generate electricity. The production process of thermal power generation needs to go through multiple links such as the combustion system, steam-water system, electrical system, and control system. Since thermal power generating units rely on steam-water circulation to convert energy and generate electricity, the quality and supply stability of steam and water are crucial to the efficiency, safety, and economy of thermal power generation.

[0003] In the existing thermal power generation steam-water supply process, the amount of steam-water supplied is usually adjusted by switching valves, but this method mainly relies on steam parameters (such as pressure, temperature) for adjustment, and is mostly passive, which can easily cause steam-water loss, leading to increased fuel energy consumption, and during the start-up and shutdown of the equipment, it is easy to cause unstable steam-water supply, affecting the combustion efficiency of the boiler and the working efficiency of the turbine, and increasing operating costs.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 - Figure 3As shown, an intelligent steam-water supply device for thermal power generation includes a boiler 1, a connecting drum 2 is fixedly installed on one side of the top of the boiler 1, a connecting pipe 3 is fixedly connected to the side of the connecting drum 2, one end of the connecting pipe 3 is fixedly connected to a steam accumulator 4, a steam quantitative controller 5 is arranged at the bottom of the steam accumulator 4, one end of the steam quantitative controller 5 is fixedly connected to a steam turbine, a condenser 11 is fixedly connected to the side of the steam turbine through a pipeline, a condensate pump 14 is fixedly connected to the bottom of the condensate pump 11 through a pipeline, and a low-pressure heater is fixedly connected to the side of the condensate pump 14 13. The low-pressure heater 13 is fixedly connected to the deaerator 10 through a pipeline. The side of the deaerator 10 is fixedly connected to a water supply pump 12. The top of the water supply pump 12 is fixedly connected to a high-pressure heater 8. A solenoid valve 9 is provided on the top of the high-pressure heater 8. The side of the solenoid valve 9 is fixedly connected to a side connected to the steam drum 2 through a pipeline. One end of the bottom of the boiler 1 is fixedly connected to an air storage tank 6 through a pipeline. One side of the air storage tank 6 is fixedly connected to an air compressor 7. One end of the air compressor 7 is fixedly connected to the top of the deaerator 10 through a pipeline. The deaerator 10 is connected to a water treatment device.

[0034] By providing the gas storage tank 6 and the air compressor 7, the oxygen discharged from the deaerator 10 can be recycled and utilized, thereby improving the combustion effect of the combustion system of the boiler 1 and reducing the loss of energy consumption.

[0035] like Figure 3 As shown, the gas storage tank 6 includes an oxygen tank 61, the top of the oxygen tank 61 is fixedly connected to an exhaust head 62, one side of the exhaust head 62 is fixedly connected to an air valve motor 64, the output end of the air valve motor 64 is fixedly connected to a connecting ball 65, the connecting ball 65 is rotatably installed inside the exhaust head 62, and a ventilation groove 66 is provided inside the connecting ball 65, the top of the exhaust head 62 is fixedly connected to a fixed cover 63, the inside of the fixed cover 63 is fixedly connected to a fixed plate 67, the inside of the fixed plate 67 is movably sleeved with a piston rod 68, the upper end of the piston rod 68 is fixedly sleeved with a limiting block 69, the inside of the fixed cover 63 is movably sleeved with an extrusion spring 610, the extrusion spring 610 is located between the limiting block 69 and the top wall of the fixed cover 63, the bottom of the piston rod 68 is fixedly connected to a movable plug 611, the movable plug 611 is movably sleeved inside the fixed cover 63, one end of the bottom of the fixed cover 63 is connected to the pipeline, and the position where the fixed cover 63 is connected to the pipeline is located below the fixed plate 67.

[0036] By utilizing the effect of the extrusion spring 610 on the limit block 69, when the connecting ball 65 rotates, the ventilation groove 66 connects the fixed cover 63 and the oxygen tank 61, and the compressed oxygen inside the oxygen tank 61 pushes the movable plug 611 to rise, compressing the extrusion spring 610. The oxygen passes through the fixed cover 63 and is transported to the combustion system of the boiler 1 through a pipeline to assist combustion of the combustion system. When the oxygen tank 61 is insufficient in oxygen, the extrusion spring 610 pushes the magnet block 59 down through its own reaction force, so that the movable plug 611 is timely blocked at the top of the exhaust head 62, thereby achieving a check effect and preventing the burning gas from entering the interior of the oxygen tank 61 and causing safety problems.

[0037] By setting up an air storage tank 6 and an air compressor 7, the water entering the deaerator 10 is treated and softened by water treatment equipment, so that when the deaerator 10 deoxygenates the soft water, the oxygen is collected and compressed by the air compressor 7 and stored in the air storage tank 6, and the first steam flow meter 213 is used to monitor the steam and water flow discharged from the exhaust port 22. When the steam and water amount discharged by the first steam flow meter 213 floats downward, the first steam flow meter 213 controls the start of the gas valve motor 64 through an electrical signal to make the connecting ball 65 rotate inside the exhaust head 62, and oxygen enters the combustion system of the boiler 1 through the pipeline, providing oxygen to assist combustion inside the combustion system, making the combustion inside the boiler 1 more complete, improving the combustion effect and heat transfer, and at the same time, realizing the short-term automatic adjustment of the steam and water supply, thereby making the steam and water production more stable and improving the stability of the steam and water supply.

[0038] Embodiment 2, as Figure 1 , Figure 4 - Figure 7 As shown, an intelligent steam-water supply device for thermal power generation, connected to a steam drum 2 including a steam drum body 21, a top of the steam drum body 21 is fixedly connected with an exhaust port 22, one side of the exhaust port 22 is provided with a first steam flow meter 213, the first steam flow meter 213 is electrically connected to a gas valve motor 64, one side of the exhaust port 22 is connected with a steam accumulator 4 through a pipeline, a support frame 23 is fixedly installed on the side of one end of the steam drum body 21, a lifting groove 24 is provided inside the support frame 23, an I-shaped frame 25 is movably sleeved inside the lifting groove 24, limiting rods 27 are fixedly installed on both sides of the bottom of the support frame 23, and a target block 212 is fixedly installed on the bottom of the support frame 23.

[0039] like Figure 4 - Figure 5As shown, a first arc plate 28 is fixedly installed on one side of the inner wall of one end of the steam envelope 21, and a first arc groove 29 is opened inside the first arc plate 28; a second arc plate 210 is fixedly installed on one side of the outer surface of one end of the steam envelope 21, and a second arc groove 211 is opened inside the second arc plate 210; the positions of the first arc groove 29 and the second arc plate 210 on the inner and outer walls of the steam envelope 21 correspond to each other; a water level positioning device 20 is slidably installed inside the first arc groove 29, and a distance measuring device 26 is slidably installed inside the second arc groove 211; the distance measuring device 26 is movably sleeved on the outer surface of the limit rod 27, and the distance measuring device 26 is movably sleeved inside the I-shaped frame 25.

[0040] like Figure 6 As shown, the water level positioning device 20 includes a first fixed sleeve 201, the internal fixed sleeve of the first fixed sleeve 201 is connected to the first magnet 202, the first support rod 203 is fixedly installed on both sides of the first fixed sleeve 201, the outer surfaces of the two ends of the first support rod 203 are rotatably installed with a rotating frame 204, the end of the rotating frame 204 away from the first fixed sleeve 201 is fixedly installed with a fixed shaft 205, the outer surface of the fixed shaft 205 is rotatably provided with a hollow ball 206, the interior of the hollow ball 206 is provided with a plurality of through holes, and the first support rod 203 is slidably installed inside the first arc groove 29.

[0041] By setting a hollow ball 206, the hollow ball 206 is hollow, and a through hole is opened inside the hollow ball 206. The hollow ball 206 rotates on the outer surface of the fixed shaft 205. Since the water inside the boiler 1 will become a steam-water mixture after being heated, the steam and water will rise, while the water will fall, forming a natural cycle. This circulation process makes the water in the steam enclosure 21 roll continuously. Through the through hole inside the hollow ball 206, the impact force of the water flow on the surface of the hollow ball 206 is suppressed, and the water flow is prevented from flowing on the same side of the hollow ball 206, thereby reducing the floating degree of the hollow ball 206. The rolling of the hollow ball 206 on the outer surface of the fixed shaft 205 slows down the impact force of the water flow on the hollow ball 206, and slows down the influence of the rolling of the water inside the steam enclosure 21 on the hollow ball 206, so that the movement of the first magnet 202 is more stable.

[0042] like Figure 7 As shown, the distance measuring device 26 includes a second fixed sleeve 261, the interior of the second fixed sleeve 261 is fixedly sleeved with a second magnet 262, both sides of the second fixed sleeve 261 are fixedly installed with second support rods 263, the outer surface of the second support rod 263 is rotatably installed with a movable frame 264, the end of the movable frame 264 close to the second fixed sleeve 261 is provided with a sliding groove 265, the interior of the movable frame 264 is slidably installed with a distance measuring sensor 266, the distance measuring sensor 266 is electrically connected to the first steam flow meter 213, and both sides of the distance measuring sensor 266 are fixedly installed with sleeve pipes 267, and the sleeve pipes 267 are slidably installed inside the sliding groove 265.

[0043] By utilizing the mutual magnetic attraction between the first magnet 202 and the second magnet 262, when the hollow ball 206 rises or falls due to the influence of the water level, the buoyancy or gravity of the hollow ball 206 will pull the first fixed sleeve 201 to rise or fall. When the first magnet 202 rises or falls, the second magnet 262 is lifted or lowered on the outside of the steam envelope 21 through the effect of magnetic attraction, and the distance sensor 266 inside the movable frame 264 is pushed to rise or fall. The distance to the target block 212 is monitored by the distance sensor 266, and the degree of water level rise or fall of the steam envelope 21 is monitored, and then the water level change inside the steam envelope 21 is monitored, and automatic water replenishment is realized through the solenoid valve 9, thereby reducing manual intervention and improving the automation level of the steam-water supply device.

[0044] Among them, the second support rod 263 is slidably installed inside the second arc groove 211, the second magnet 262 is magnetically attracted to the first magnet 202, the sleeve 267 is movably sleeved on the outer surface of the limit rod 27, the position of the ranging sensor 266 corresponds to the position of the target block 212, and the movable frame 264 is movably sleeved on both sides of the I-frame 25 at one end away from the second fixed sleeve 261.

[0045] When the first magnet 202 and the second magnet 262 are lifted and lowered in an arc shape on both sides of the steam bag body 21, the sleeve tubes 267 at both ends of the distance measuring sensor 266 are moved inside the sliding groove 265 through the sliding groove 265, and the up and down movement of the distance measuring sensor 266 is adjusted by lifting and lowering the sleeve tube 267 on the outer surface of the limit rod 27 and the lifting and lowering of the I-beam 25 inside the lifting groove 24.

[0046] As attached Figure 1 , Figure 8 - Fig. 9 As shown, the steam quantitative controller 5 includes an exhaust hood 51, a steam-water pipe 52 is fixedly installed on one side of the exhaust hood 51, the steam-water pipe 52 is connected to the steam accumulator 4, a plurality of limit frames 55 are fixedly installed on the inner wall of the exhaust hood 51 away from the steam-water pipe 52, and movable grooves 56 are provided inside the plurality of limit frames 55, a plurality of electromagnets 57 are fixedly installed on the top of the exhaust hood 51, an exhaust pipe 53 is fixedly connected to one side of the exhaust hood 51, a second steam flow meter 54 is arranged inside the exhaust pipe 53, the exhaust pipe 53 is connected to one side of the steam turbine, and a plurality of extrusion blocks 58 are movably sleeved inside the exhaust hood 51.

[0047] The steam accumulator 4 is used to store steam and water, so that the steam and water discharged from the steam drum 2 can be buffered, so that the steam and water supply can be more stable, the efficiency of the steam and water supply can be improved, and the steam and water supply can be more stable and reliable.

[0048] Among them, limit strips 511 are fixedly installed on both sides of multiple extrusion blocks 58, a magnet block 59 is fixedly installed on the top of the extrusion block 58, the limit strip 511 is movably sleeved inside the movable groove 56, and a return spring 510 is movably sleeved on the outer surface of the magnet block 59. The return spring 510 is located between the extrusion block 58 and the top wall of the exhaust hood 51. The side of the extrusion block 58 close to the soda pipe 52 is an arc surface, and the positions of the electromagnet 57 and the magnet block 59 correspond.

[0049] Among them, the steam-water pipe 52 includes a steam pipe body 521, which is fixedly installed on one side of the exhaust hood 51. A plurality of connecting nozzles 522 are fixedly connected to the side of the steam pipe body 521 close to the exhaust hood 51. The interiors of the plurality of connecting nozzles 522 are movably connected with an exhaust inner pipe 523. Both sides of the interior of the exhaust inner pipe 523 are provided with air outlet grooves 524. One side of the exhaust inner pipe 523 is connected with the connecting nozzle 522. An arc-shaped top plug 525 is fixedly installed on the side of the exhaust inner pipe 523 away from the steam pipe body 521. One side of the arc-shaped top plug 525 is a circular arc surface, and an extrusion block 58 is movably installed on one side of the arc-shaped top plug 525.

[0050] By utilizing the interaction between the arc surface of the extrusion block 58 and the arc surface of the arc-shaped top plug 525, when the electromagnet 57 is working, the magnet block 59 is magnetically attracted to make the extrusion block 58 rise. At this time, the arc-shaped top plug 525 is not squeezed, and the gas pressure of the soda pushes the exhaust inner tube 523 to move sideways inside the connecting nozzle 522, so that the soda inside the steam pipe body 521 is discharged through the air outlet groove 524, and the discharge amount of soda is controlled through multiple exhaust inner tubes 523, so as to achieve quantitative discharge of soda and reduce the loss of soda.

[0051] It should be noted that the present invention is an intelligent steam-water supply device for thermal power generation. When in use, the fuel enters the power plant from the fuel warehouse or storage facility through a conveyor belt, a pipeline or a fuel vehicle. The fuel is pre-processed (such as crushed and ground) and enters the boiler 1 or the combustion chamber. In the boiler 1, the fuel is mixed with air or oxygen and burned to generate high-temperature combustion gas. The high-temperature combustion gas transfers heat to water through the heating surface in the boiler 1, and the water is heated into steam-water. The steam-water mixture from the water-cooled wall enters the steam enclosure 21 through the introduction pipe. After the steam-water mixture entering the steam enclosure 21 is separated, the steam-water is stored in the steam accumulator 4 and transported to the steam turbine through the steam quantitative controller 5.

[0052] The high-temperature and high-pressure steam and water at the outlet of the steam turbine enter the condenser 11, and come into contact with the cooling medium (usually water) during the internal cooling process. The steam and water dissipate heat in the condenser 11 and condense into water, and then are transported to the low-pressure heater 13 by the condensate pump 14 for simple heating, and are deoxidized again by the deaerator 10, and enter the high-pressure heater 8 through the feed water pump 12 for reheating, and are transported to the inside of the connected steam drum 2. In addition, the external water passes through the water treatment equipment, and then enters the deaerator 10 for deoxidation after being softened, and the connected steam drum 2 is supplemented with water through the feed water pump 12 and the high-pressure heater 8;

[0053] When the deaerator 10 deoxygenates the soft water, the oxygen is collected and compressed by the air compressor 7 and stored in the gas storage tank 6. The first steam flow meter 213 is used to monitor the steam-water flow rate discharged from the exhaust port 22. When the steam-water amount discharged by the first steam flow meter 213 floats downward, the first steam flow meter 213 controls the valve motor 64 to start through an electrical signal, so that the connecting ball 65 rotates inside the exhaust head 62, and the oxygen enters the combustion system of the boiler 1 through the pipeline, providing oxygen to the combustion system to assist combustion, so that the combustion inside the boiler 1 is more complete. At the same time, the automatic adjustment of the steam-water supply is realized for a short time, so that the steam-water generation is more stable, and the heat transfer during heating is avoided when the fuel is not fully burned.

[0054] In addition, by utilizing the mutual magnetic attraction between the first magnet 202 and the second magnet 262, when the hollow ball 206 is affected by the water level and rises and falls, the buoyancy or gravity of the hollow ball 206 will pull the first fixing sleeve 201 to rise and fall. When the first magnet 202 is rising and falling, the second magnet 262 is lifted and lowered on the outside of the steam envelope 21 by the effect of magnetic attraction, and the distance sensor 266 inside the movable frame 264 is pushed to rise and fall. The distance to the target block 212 is monitored by the distance sensor 266, the degree of the water level rise and fall of the steam envelope 21 is monitored, and then the water level change inside the steam envelope 21 is monitored. When the water level inside the steam envelope 21 drops, the distance sensor 266 monitors the distance to the target block 212. Increase, when a certain threshold is reached, the distance sensor 266 controls the solenoid valve 9 to start through an electrical signal, so that the water in the deaerator 10 passes through the water supply pump 12, is heated in the high-pressure heater 8, and then enters the interior of the connected steam drum 2. When the hollow ball 206 rises with the water level, it pulls the first magnet 202 to rise, and the second magnet 262 rises synchronously, so that the distance sensor 266 rises, and when the distance between the distance sensor 266 and the target block 212 meets the requirements, the distance sensor 266 controls the solenoid valve 9 to stop working through an electrical signal, so as to realize automatic water replenishment inside the steam drum 21, maintain a stable supply of steam and water, reduce manual intervention, and improve the automation level of the steam and water supply device;

[0055] By setting up a plurality of exhaust inner tubes 523, according to the steam turbine's demand for steam and water, an appropriate amount of electromagnets 57 are started. When an appropriate amount of electromagnets 57 are working, the magnet block 59 is magnetically attracted to make the extrusion block 58 rise. At this time, the return spring 510 is compressed, and the arc-shaped top plug 525 is not squeezed. The steam and water push the exhaust inner tube 523 to move sideways at the connecting nozzle 522 through air pressure, so that the steam and water inside the steam pipe body 521 are discharged through the air outlet groove 524 and monitored by the second steam flow meter 54. When the demand for steam and water decreases, the corresponding electromagnet 57 is automatically controlled to stop working, so that the electromagnet 57 loses its magnetism to the magnet block 59, and the extrusion block 58 is pushed downward by the reaction force of the return spring 510, so that the extrusion block 58 is squeezed to the side of the arc-shaped top plug 525, and the exhaust inner tube 523 is pushed to the inside of the connecting nozzle 522. The limit frame 55 is blocked at the side of the connecting nozzle 522, and the exhaust of the corresponding air outlet groove 524 is stopped, so as to realize the regulation of the steam and water supply amount.
