[0017] The beneficial effects of the present invention are:

[0018] 1. In the present invention, through the design of the exchange component, the waste smoke generated by the boiler main body is introduced into the interior of the smoke pipe, and the flue gas is filtered by the filter net. The flue gas is introduced into the interior of the exchanger, and the water flow is introduced into the interior of the water inlet pipe. The water inlet pipe introduces the water flow into the interior of the exchanger, so that the water flow is introduced into the interior of the first guide pipe. When the water flow is introduced into the interior of the first guide pipe, it contacts the first spiral guide groove, and the water flow is spirally accelerated and guided by the first spiral guide groove to increase the flow rate of the water flow. When the water flow is accelerated by the first spiral guide groove, the water flow is introduced into the interior of the second guide pipe through the guide head and is accelerated again by the second spiral guide groove. It contacts the spiral blade and drives the spiral blade to rotate, so that the water flow can be dispersed. When the flue gas is introduced into the interior of the exchanger through the smoke pipe, the rotation of the spiral blade drives the flue gas to move and contact the water flow, and the flue gas is sucked into the interior of the third guide pipe. Inside the third guide pipe, it is mixed with water and gas. When the flue gas and the water flow are introduced into the interior of the third guide pipe, they are introduced into the interior of the connection shell along the third guide pipe. Through the connection disk and the multiple groups of through grooves inside it, the water flow is dispersed. The water flow and the flue gas are effectively heat-exchanged inside the connection shell, so that the water flow can be heated. The heated water flow is discharged through the delivery pipe. The high-temperature waste gas can heat the water inside the exchanger, which is used for the utilization of the waste heat of the high-temperature waste gas and reduces the waste of energy;

[0019] 2. In the present invention, through the design of the cleaning component, when too much impurities and dust accumulate on the surface area of the filter net, the first driving motor is started to drive the driving screw to rotate, so that the moving shell can be displaced. The double-shaft motor is started to drive the two bevel gears to rotate, so that the bevel gear disk rotates and drives the convex block to be displaced. When the convex block rotates, it contacts the guide block, so that the fixed rod can rotate and drives the rotating rod to rotate. Thus, the scraper can rotate to clean the impurities and dust on the surface of the filter net. When the scraper rotates, it drives the connecting head to be displaced, so that the connecting head is displaced into the interior of the docking head. The circulating pump is started to introduce the water flow inside the water storage tank into the interior of the connecting head, so that the water flow can be sprayed on the surface of the filter net through the water spray nozzle, which is convenient for the scraper to clean the filter net.

The guide head 10 is fixedly connected to the end of the first guide pipe 9 away from the water inlet pipe 4. Multiple groups of second guide pipes 11 are all fixedly connected inside the exchanger 3 and outside multiple groups of guide heads 10. The spiral blade 12 is rotatably connected to the end of the second guide pipe 11 away from the guide head 10. Multiple groups of third guide pipes 13 are all fixedly connected inside the exchanger 3 and away from multiple groups of spiral blades 12. The connection shell 14 is fixedly connected inside the exchanger 3 and away from one end of the water inlet pipe 4;

[0037] The cleaning assembly 8 is used to clean the impurities on the surface of the filter screen 6.

[0038] In this embodiment, a furnace water wall 1008 is provided on the outer side of the burner 1001 and inside the boiler main body 1. A furnace water wall outlet is provided at the bottom of the furnace water wall 1008. A nano-aerogel thermal insulation material 1009 is provided on the outer side of the furnace water wall 1008. An air insulation layer 1010 is provided on the outer side of the nano-aerogel thermal insulation material 1009 and on the inner wall of the boiler main body 1. Fireproof thermal insulation layers 1011 are provided on the outer sides of the high-temperature section coil 1002 and the low-temperature section coil 1003 and on the inner wall of the boiler main body 1. The superheater 1004 extends to the outside of the boiler main body 1 and is respectively provided with a superheater inlet and a superheater outlet. The economizer 1005 extends to the outside of the boiler main body 1 and is provided with a boiler feed water inlet. A high-temperature section water wall 1013 is provided inside the fireproof thermal insulation layer 1011. The outlet of the economizer 1005 is connected to the inlet of the high-temperature section water wall 1013 through a first connecting pipe 1012. The low-temperature section coil 1003 is connected to the high-temperature section coil 1002 through a second connecting pipe 1014. The feed water first enters the economizer 1005, which is formed by staggered arrangement of multiple groups of finned tubes, then passes through the high-temperature section water wall 1013 and then enters the low-temperature section coil 1003. The low-temperature section coil 1003 is formed by stacking and connecting several layers of coil in the shape of mosquito coils in series; then it enters the high-temperature section coil 1002 (the high-temperature section coil 1002 is in the shape of mosquito coils);Then it enters the furnace water wall 1008 coil (spiral closely arranged cylindrical structure), where it is heated and vaporized to generate steam. During startup conditions, the steam at the outlet of the furnace water wall 1008 is a steam-water mixture, which enters the unheated external startup separator for efficient separation. The saturated steam coming out of the separator then enters the superheat section coil composed of mosquito coil-shaped coils. The superheat section coil is located between the high-temperature section coil 1002 and the low-temperature section coil 1003. The steam is continuously heated by the superheat section coil to form low-pressure superheated steam for external output. During once-through operation, the external startup separator is cut out of the system through a switching valve, and the steam at the furnace outlet no longer passes through the startup separator. The steam at the furnace outlet directly enters the superheat section coil and is continuously heated by the superheat section coil, and finally the output parameter is ultra-supercritical superheated steam. All the coils are connected in series, and the whole coil is a single-flow continuous steel pipe. The inner cavity formed by the lower half of the water wall coil is the combustion chamber. The pilot gas is ignited by high-voltage ignition to form a pilot flame. After the main fuel natural gas is sent in, it burns fully in the combustion chamber. On the one hand, it heats the surrounding water wall tubes, and on the other hand, the high-temperature flue gas generated by combustion rises and is discharged from the chimney after convective heat transfer through the gaps between the tubes of the flat coil. The feed water of the boiler is injected from the inlet of the top economizer 1005 under the action of a water pump. After passing through the economizer 1005, it flows along the tubes under the drive of pressure all the way to the high-temperature section water wall 1013, the low-temperature section coil 1003, the high-temperature section coil 1002, the furnace water wall 1008 and the superheater, forming a countercurrent with the flue gas, thus ensuring a high heat exchange efficiency. The furnace is a steel pipe connected by butt welding and wound into a tightly abutting spiral tube, which is cylindrical in shape. The furnace outlet is butted with the flat coil wound into a mosquito coil shape, and the formed gap is very small, and a tightly abutting spiral tube water wall (high-temperature section water wall 1013) is sleeved outside the joint. Therefore, the furnace outlet of this structure is directly butted with the convective heating surface without air leakage.;

[0039] In this embodiment, a first guide block 15 is fixedly connected inside the first guide tube 9. A first spiral guide groove 16 is formed between the first guide block 15 and the first guide tube 9. The end of the guide head 10 away from the first guide tube 9 is designed with a conical structure. When water flow is introduced into the inside of the water inlet pipe 4, the water inlet pipe 4 guides the water flow into the inside of the exchanger 3, so that the water flow is introduced into the inside of the first guide tube 9. When the water flow is introduced into the inside of the first guide tube 9, it contacts the first spiral guide groove 16, and the water flow is spirally accelerated and guided through the first spiral guide groove 16 to increase the flow rate of the water flow.

[0040] In this embodiment, a second guiding block 17 is fixedly connected inside the second guiding tube 11. An outer side of the second guiding block 17 and inside the second guiding tube 11, a spiral sheet 18 is fixedly connected. A second spiral guiding groove 19 is formed among the spiral sheet 18, the second guiding block 17 and the second guiding tube 11. The spiral blade 12 is rotatably connected to the second guiding block 17. When the water flow is accelerated through the first spiral guiding groove 16, the water flow is guided into the inside of the second guiding tube 11 through the guiding head 10, and is accelerated again through the second spiral guiding groove 19, contacts the spiral blade 12, and drives the spiral blade 12 to rotate, so that the water flow can be dispersed. When the flue gas is introduced into the inside of the exchanger 3 through the flue tube 2, the rotation of the spiral blade 12 drives the flue gas to displace, contacts the water flow, and is sucked into the inside of the third guiding tube 13, and is mixed with water and gas inside the third guiding tube 13.

[0041] In this embodiment, a connection disk 20 is fixedly connected inside the connection shell 14. A plurality of groups of through grooves 21 are formed inside the connection disk 20. The connection disk 20 extends to the outside of the exchanger 3 and is fixedly connected with a delivery pipe. When the flue gas and the water flow are introduced into the inside of the third guiding tube 13, they are guided into the inside of the connection shell 14 along the third guiding tube 13. Through the cooperation of the connection disk 20 and the plurality of groups of through grooves 21 inside it, the water flow is dispersed. The water flow and the flue gas are effectively heat-exchanged inside the connection shell 14, so that the water flow can be heated, and the heated water flow is discharged through the delivery pipe.

[0042] In this embodiment, a sealing cover 22 is rotatably connected to the top of the flue tube 2 and above the filter net 6. The moving shell 7 is slidably connected to the flue tube 2. A driving screw 23 is rotatably connected to the inside of the flue tube 2 and outside the moving shell 7. The moving shell 7 is threadedly connected to the driving screw 23. An outer side of the driving screw 23 is fixedly connected to a driving end of a first driving motor. When the first driving motor is started, the driving screw 23 is driven to rotate, so that the moving shell 7 can be displaced.

[0043] In this embodiment, the cleaning assembly 8 is composed of a scraping plate 24, two groups of connecting frames 25, two groups of rotating rods 26, two groups of fixing rods 27, two groups of bevel gear disks 28 and two groups of water storage tanks 29. The scraping plate 24 is rotatably connected to one end of the moving shell 7 close to the filter net 6. The two groups of connecting frames 25 are respectively fixedly connected to both ends inside the moving shell 7. The rotating rod 26 is rotatably connected to the outside of the connecting frame 25. The fixing rod 27 is fixedly connected to the connection part of the rotating rod 26 and the connecting frame 25. The bevel gear disk 28 is rotatably connected to one end of the connecting frame 25 far from the rotating rod 26. The two groups of water storage tanks 29 are both fixedly connected to both ends inside the moving shell 7 and outside the two groups of connecting frames 25. When too much impurities and dust accumulate on the surface of the filter net 6, the filter net 6 can be cleaned through the cleaning assembly 8 to prevent the impurities and dust from affecting the operation of the filter net 6.

[0044] In this embodiment, one end of the rotating rod 26 away from the connecting frame 25 is fixedly connected to the scraping plate 24. The fixed rod 27 is rotatably connected to the connecting frame 25. One end of the fixed rod 27 away from the rotating rod 26 is fixedly connected to a fixed block 30. Both ends of the fixed block 30 near one end of the bevel gear disk 28 are fixedly connected with cylinders 31. One end of the bevel gear disk 28 near the fixed block 30 is fixedly connected with a convex block 32. The outer side of the bevel gear disk 28 is meshed with a bevel gear 33. The bevel gear 33 is rotatably connected to the connecting frame 25. The two bevel gears 33 are connected by a double-shaft motor. The two driving ends of the double-shaft motor are respectively fixedly connected to the two bevel gears 33. Start the double-shaft motor to drive the two bevel gears 33 to rotate, so that the bevel gear disk 28 rotates, driving the convex block 32 to displace. When the convex block 32 rotates, it contacts the cylinder 31, enabling the fixed rod 27 to rotate, driving the rotating rod 26 to rotate, and thus enabling the scraping blade to rotate to clean the impurities and dust on the surface of the filter screen 6.

[0045] In this embodiment, multiple water spray nozzles 34 are provided at one end of the scraping plate 24 close to the filter screen 6. Both ends of the scraping plate 24 are fixedly connected with connecting heads 35. One end of the water storage tank 29 close to the connecting head 35 is fixedly connected with a docking head 36. The docking head 36 extends into the water storage tank 29 and is provided with a circulation pump inside. The connecting head 35 and the docking head 36 have a certain elasticity. When the scraping plate 24 rotates, it drives the connecting head 35 to displace, so that the connecting head 35 displaces into the docking head 36. Start the circulation pump to introduce the water flow inside the water storage tank 29 into the connecting head 35, so that the water flow can be sprayed on the surface of the filter screen 6 through the water spray nozzles 34, facilitating the scraping plate 24 to clean the filter screen 6.

[0046] Embodiment: In actual use, the waste smoke generated by the boiler main body 1 is introduced into the inside of the smoke pipe 2, and the flue gas is filtered by the filter net 6. The flue gas is introduced into the inside of the exchanger 3, and the water flow is introduced into the inside of the water inlet pipe 4. The water inlet pipe 4 introduces the water flow into the inside of the exchanger 3, so that the water flow is introduced into the inside of the first guide pipe 9. When the water flow is introduced into the inside of the first guide pipe 9, it contacts the first spiral guide groove 16, and the water flow is spirally accelerated and guided through the first spiral guide groove 16 to increase the flow rate of the water flow. When the water flow is accelerated through the first spiral guide groove 16, the water flow is introduced into the inside of the second guide pipe 11 through the guide head 10 and is accelerated again through the second spiral guide groove 19, contacts the spiral blade 12, and drives the spiral blade 12 to rotate, so that the water flow can be dispersed. When the flue gas is introduced into the inside of the exchanger 3 through the smoke pipe 2, the rotation of the spiral blade 12 drives the flue gas to displace, contacts the water flow, and is sucked into the inside of the third guide pipe 13. Inside the third guide pipe 13, it is mixed with water and gas. When the flue gas and the water flow are introduced into the inside of the third guide pipe 13, they are introduced into the inside of the connection shell 14 along the third guide pipe 13. Through the connection disk 20 and the multiple groups of through grooves 21 inside it, the water flow is dispersed, and the water flow and the flue gas are effectively heat-exchanged inside the connection shell 14, so that the water flow can be heated. The heated water flow is discharged through the delivery pipe. When too many impurities and dust accumulate on the surface area of the filter net 6, the first drive motor is started to drive the drive screw 23 to rotate, so that the moving shell 7 can displace. The double-shaft motor is started to drive the two bevel gears 33 to rotate, so that the bevel gear disk 28 rotates, driving the convex block 32 to displace. When the convex block 32 rotates, it contacts the cylinder 31, so that the fixed rod 27 can rotate, driving the rotating rod 26 to rotate, and thus the scraping blade can rotate to clean the impurities and dust on the surface of the filter net 6. When the scraping plate 24 rotates, it drives the connecting head 35 to displace, so that the connecting head 35 displaces into the inside of the docking head 36. The circulating pump is started to introduce the water flow inside the water storage tank 29 into the inside of the connecting head 35, so that the water flow can be sprayed on the surface of the filter net 6 through the water spray port 34, facilitating the scraping plate 24 to clean the filter net 6.
