Description

Technical Field

[0001] The invention relates to the technical field of heating boilers, and in particular to an integrated heating boiler and heat exchanger. Background Art

[0002] The working principle of the integrated heating boiler and heat exchanger is to use the waste heat of the flue gas generated by combustion to preheat the medium in the pipeline.

It has high thermal efficiency, and the medium does not contact the boiler, avoiding the formation of attachments on the inner wall of the boiler. However, since the medium is non-contact between the medium and the boiler, the medium heats up slowly, so the heat exchange requirements are met by increasing the length of the boiler, and the flame combustion is concentrated at the fuel nozzle.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-10 The embodiment of the present invention provides a heating boiler and heat exchanger integrated machine, including a shell 1, in which a preheating flue 101 and a heating chamber 102 are separated by a partition component 2, including:

[0033] The boiler assembly 3 includes a boiler drum 33 and a smoke exhaust pipe 34. The boiler drum 33 is rotatably connected to the heating chamber 102. The boiler drum 33 and the preheating flue 101 are connected via the smoke exhaust pipe 34.

[0034] The heat exchange component 5 is arranged in the preheating flue 101 and the heating chamber 102 so as to absorb the heat of the preheating flue 101 and the heating chamber 102;

[0035] The burner 4 is used to heat the boiler drum 33 and synchronously drive the boiler drum 33 to rotate, so that the boiler drum 33 is evenly heated.

[0036] The burner 4 delivers gas and air into the boiler tube 33, and the heat generated by the combustion heats the boiler tube 33, and the smoke generated by the combustion of the gas is discharged into the preheating flue 101 through the exhaust pipe 34, and the heat exchange component 5 is arranged in the preheating flue 101 and the heating chamber 102 at the same time, so the heat exchange component 5 can absorb the heat in the preheating flue 101 and the heating chamber 102 to increase the internal energy of the medium it delivers, and the heat exchange component 5 continuously absorbs the heat in the preheating flue 101 and the heating chamber 102 to achieve the purpose of heat exchange. The burner 4 is arranged in the shell 1, and the heat generated by the burner 4 during combustion heats the boiler tube 33. The generated flue gas is transported to the preheating flue 101 through the smoke exhaust pipe 34. During the combustion process, air injection is required to achieve combustion conditions through the combination of oxygen and fuel. The air injection type uses air to drive the burner 4 to rotate, so that the flame during combustion can evenly roast the boiler barrel 33. In this way, the boiler barrel 33 can be more evenly deformed when heated, avoiding irregular deformation and causing damage to the boiler barrel 33, thereby improving the use of the boiler barrel 33. First, the boiler barrel 33 is evenly roasted so that the entire boiler barrel 33 is heated. In this way, the temperature difference between each area of ​​the heating chamber 102 is reduced, which helps to heat up the heat exchange component 5 and improve the heating effect of the heat exchange component 5.

[0037] The partition assembly 2 includes a first partition plate 21, a pipe opening 22 and a second partition plate 23. The second partition plate 23 is fixedly installed on the upper part of the shell 1. The heating chamber 102 is separated by the second partition plate 23. Several first partition plates 21 are installed in the shell 1. The pipe opening 22 is opened in the first partition plate 21 to form a corrugated preheating flue 101.

[0038] The second partition plate 23 is fixedly installed on the upper part of the shell 1, and a heating chamber 102 can be separated in the upper part of the shell 1, and the boiler barrel 33 is arranged in the heating chamber 102, so that the heating chamber 102 is heated by the boiler barrel 33, and the preheating flue 101 is separated in the middle and lower part of the shell 1 by the first partition plate 21, and the preheating flue 101 is formed in a corrugated shape. In this way, during the heating process of the boiler barrel 33, the flue gas generated by the combustion is transported into the preheating flue 101 through the exhaust pipe 34, and then the preheating flue 101 is heated by the waste heat of the flue gas. When the medium in the heat exchange component 5 flows through the preheating flue 101, the flue gas can be heated by the flue gas. The heat exchange component 5 is heated up and moves with the medium from bottom to top, while the flue gas moves from top to bottom along the preheating flue 101. In this way, the temperature of the medium will continue to rise as it is transported, and the medium in the heat exchange component 5 is heated by the waste heat of the flue gas. Finally, the medium is preheated in advance to maximize the use of the heat generated by the combustion of the fuel. When the medium reaches the heating room 102 through the heat exchange component 5, the boiler barrel 33 is in the heating room 102. The temperature of the heating room 102 is much higher than the temperature of the preheating flue 101. Therefore, when the medium enters the heating room 102, the temperature is increased again so that the medium can reach the specified stability.

[0039] The heat exchange component 5 includes a medium injection pipe 54, a preheating pipe 51, a heating pipe 52 and a medium discharge pipe 53 which are connected in sequence. The preheating pipe 51 is arranged and extends along the preheating flue 101. The heating pipe 52 is arranged in the heating room 102. The medium discharge pipe 53 extends from the upper part of the heating room 102 to the outside of the shell 1. The medium injection pipe 54 enters from the lower part of the shell 1.

[0040] The heat exchange component 5 includes, from bottom to top, a medium injection pipe 54, a preheating pipe 51, a heating pipe 52 and a medium discharge pipe 53, which are respectively connected to the external heat dissipation pipe through the medium injection pipe 54 and the medium discharge pipe 53. The heat dissipation pipe is used in conjunction with a water pump to circulate the medium inside. The medium with a lower temperature is injected into the preheating pipe 51 from the medium injection pipe 54. The preheating pipe 51 extends along the preheating flue 101. As the medium circulates in the preheating pipe 51, the medium can be gradually heated by the preheating pipe 51. The medium is transported by the preheating pipe 51 and is gradually heated as the transport proceeds. The preheating pipe 51 transports the medium to the heating pipe 52, which is located in the heating chamber 102. The temperature of the heating chamber 102 is much higher than the temperature of the preheating flue 101. Therefore, when the medium flows to the heating pipe 52, the temperature of the medium will rise again until it reaches the required temperature.

[0041] In another embodiment of the present invention, a water body is disposed at the lower portion of the heating chamber 102 . The water body generates high-temperature steam when heated. The high-temperature steam is collected at the upper portion of the heating chamber 102 to improve the heat exchange efficiency of the heating pipe 52 .

[0042] In an embodiment of the present invention, the upper part of the shell 1 is rotatably connected to the core shaft 32, and a sealing disk 31 is fixedly installed at the end of the core shaft 32. A sleeve 35 is arranged between the sealing disk 31 and the boiler barrel 33 to form a smoke exhaust gap. The sealing disk 31, the sleeve 35 and the boiler barrel 33 are fixedly installed by bolts 36, and the smoke exhaust pipe 34 is covered outside the smoke exhaust gap.

[0043] One end of the core shaft 32 is rotatably connected in the shell 1, and the core shaft 32 is located in the heating chamber 102. A sealing disk 31 is fixed to the other end of the core shaft 32. When the sealing disk 31 rotates, the core shaft 32 can be synchronously driven to rotate. Similarly, the setting of the core shaft 32 also limits the sealing disk 31, so that the sealing disk 31 can only rotate. A sleeve 35 is provided between the sealing disk 31 and the boiler barrel 33, and the bolt 36 penetrates the sealing disk 31 and the sleeve 35 and is screwed into the boiler barrel 33, so that the sealing disk 31 and the boiler barrel 33 are supported by the sleeve 35 to form a smoke exhaust gap. In this way, when the fuel is burned in the boiler barrel 33, the generated smoke will enter the smoke exhaust pipe 34 through the smoke exhaust gap, and then be transported into the preheating flue 101 through the smoke exhaust pipe 34, so that the preheating flue 101 is heated by the smoke generated during combustion.

[0044] In the embodiments of the present invention, please refer to Figure 4-6 The burner 4 includes a diverter head 41, an air duct 42, an air supply pipe 43, a paddle 44 and a sealing portion. The diverter head 41 and the boiler barrel 33 are rotatably sealed by the sealing portion. One end of the air supply pipe 43 passes through the diverter head 41 and extends to the inside of the boiler barrel 33. The air duct 42 is connected to the diverter head 41. The paddle 44 is fixedly arranged in the boiler barrel 33. The low-temperature area 331 is separated in the boiler barrel 33 by the paddle 44.

[0045] An air pump 6 is fixedly installed outside the housing 1 , and an output end of the air pump 6 is connected to the air duct 42 .

[0046] The splitter head 41 is fixedly installed in the shell 1. The air delivered by the air pump 6 can be injected into the splitter head 41 through the arrangement of the air duct 42. The air is then delivered to the boiler barrel 33 through the splitter head 41. The gas pipe 43 penetrates the splitter head 41 and is plugged into the boiler barrel 33. The fuel can be delivered to the boiler barrel 33 through the arrangement of the gas pipe 43. An ignition head is arranged at the end of the gas pipe 43 for igniting the fuel delivered by the gas pipe 43. The inside of the boiler barrel 33 is separated by a paddle 44, and the paddle 44 and the gas pipe 43 are rotatably connected, so that The diverter head 41 injects air, and the air flows through the blades 44. The aerodynamic force generated on the blades 44 makes it have a rotating tendency, thereby making the blades 44 drive the boiler barrel 33 to rotate, while the gas pipe 43 is always in a static state. Through the rotation of the boiler barrel 33, the boiler barrel 33 can be evenly roasted and burned when the fuel is burned. In this way, the boiler barrel 33 is more evenly deformed, and the axial deformation of the boiler barrel 33 is more even, which reduces the axial runout after heating, thereby improving the service life of the boiler barrel 33.

[0047] In the above embodiment, since the diverter head 41 always blows in external cold air, it is blocked by the blades 44, and the heat generated by the combustion is blocked outside the low-temperature area 331. The heating of the low-temperature area 331 depends on the heat conduction of the boiler barrel 33. However, since the diverter head 41 always blows in cold air, the cold air has a cooling effect on the end of the boiler barrel 33, so as to cooperate with the blades 44 to form a low-temperature area 331 in the boiler barrel 33. The formation of the low-temperature area 331 can reduce the radial deformation of the end of the boiler barrel 33, so that the boiler barrel 33 and the diverter head 41 are better combined, which helps to improve the sealing between the boiler barrel 33 and the diverter head 41.

[0048] In the embodiment of the present invention, please refer to Figure 8 A collecting chamber 47 is provided inside the flow divider 41, and a through hole 46 is provided on one side of the flow divider 41 close to the boiler barrel 33. The collecting chamber 47 and the low temperature area 331 are connected through the through hole 46. The collecting chamber 47 is provided inside the flow divider 41, and external air can be injected into the collecting chamber 47 through the air duct 42. Since the through hole 46 is connected to the collecting chamber 47, a large amount of air in the collecting chamber 47 will flow out from the through hole 46 into the boiler barrel 33 to assist the combustion of the fuel in the boiler barrel 33.

[0049] In the embodiments of the present invention, please refer to Figure 6-7The sealing portion includes a first annular groove 334, a first air bag 335, and a first flow channel 336. The first annular groove 334 is opened inside the boiler barrel 33. The first air bag 335 is arranged in the first annular groove 334. The first flow channel 336 is opened inside the boiler barrel 33. One end of the first flow channel 336 is connected to the low-temperature area 331, and the other end of the first flow channel 336 is connected to the first air bag 335.

[0050] The first annular groove 334 is formed on the inner wall of the boiler barrel 33. The first airbag 335 is arranged in the first annular groove 334. The sealing between the boiler barrel 33 and the diverter 41 can be improved by the arrangement of the first airbag 335. The first flow channel 336 connected to the first airbag 335 is formed at the end of the boiler barrel 33. During use, the air flowing in through the through hole 46 will be injected into the boiler barrel 33, so that the pressure at the end of the boiler barrel 33 increases. Under the action of pressure, a part of the air will be injected into the first airbag 335 through the first flow channel 336, so that the first airbag 335 expands to achieve better sealing. After long-term use, when the injection pressure increases, the first airbag 335 will produce a corresponding pressure increase accordingly. In this way, the first airbag 335 has a function of adaptively adapting the wind pressure size to further improve the sealing.

[0051] In another embodiment of the present invention, please refer to Figure 8-9 The sealing part also includes a second annular groove 411, a second air bag 413, a second flow channel 412, an annular air channel 339, a third flow channel 414 and a fourth flow channel 338. The second annular groove 411 is opened in the diverter head 41, the second air bag 413 is arranged in the second annular groove 411, the second flow channel 412 is opened in the upper part of the diverter head 41, the movement of the second flow channel 412 is connected to the low-temperature area 331, the other end of the second flow channel 412 is connected to the second air bag 413, the third flow channel 414 is opened in the lower part of the diverter head 41, the annular air channel 339 is opened on the inner wall of the boiler barrel 33, the third flow channel 414 is connected to the annular air channel 339, the fourth flow channel 338 is opened in the interior of the boiler barrel 33, one end of the fourth flow channel 338 is connected to the annular air channel 339, and the other end of the fourth flow channel 338 extends to the middle of the boiler barrel 33.

[0052] A first inner neck 332 is disposed in the middle of the boiler drum 33 , and second inner necks 333 are disposed on both sides of the first inner neck 332 .

[0053] The opening position of the second annular groove 411 corresponds to the first annular groove 334. The second annular groove 411 is opened on the outside of the diverter head 41, and the second air bag 413 is arranged inside the second annular groove 411. First, through the opening of the second flow channel 412, the second air bag 413 and the interior of the boiler barrel 33 are connected, so that the air inside the boiler barrel 33 can flow into the second air bag 413 through the second flow channel 412, and the opened third flow channel 414 is also connected to the second air bag 413, and the annular air channel 339 opened on the inner wall of the boiler barrel 33 is connected to the third flow channel 414. In this way, it is ensured that when the boiler barrel 33 rotates, the air in the third flow channel 414 can always flow into the annular air channel 339, and the annular air channel 339 is connected to the fourth flow channel 338, and the fourth flow channel 338 is also opened in the boiler barrel 33, and One end of the fourth flow channel 338 is connected to the annular air channel 339, and the other end is connected to the middle of the boiler barrel 33. A first inner neck 332 and a second inner neck 333 on both sides thereof are arranged in the middle of the boiler barrel 33, and the other end opening of the fourth flow channel 338 is located at the first inner neck 332. When the fuel and air delivery are constant, the flow velocity at the first inner neck 332 is relatively large, and the pressure on the opening in the middle of the fourth flow channel 338 is relatively small. Therefore, air will continuously flow into the second airbag 413, and then be discharged from the second airbag 413 through the fourth flow channel 338. In this way, the pressure of the second airbag 413 will be lower than that of the first airbag 335, and the second airbag 413 will be squeezed and deformed by the first airbag 335, which helps to increase the contact surface between the two and improve the sealing effect. It also reduces the generation of friction after deformation and improves the service life.

[0054] In the above embodiment, since the air in the second airbag 413 is always in a flowing state, it can have a heat dissipation effect to reduce the temperature of the second airbag 413. Correspondingly, under the action of heat transfer, it also has a certain cooling effect on the first airbag 335, thereby reducing the temperature of the first airbag 335 and the second airbag 413, and further improving the service life.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
