Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to a condensate water treatment device and a condensing gas water heater. Background Technology

[0002] The working principle of a condensing gas water heater is to send the flue gas, which has been cooled by the main heat exchanger, into the condensing shell of the condensing heat exchange device. Before the cold water is sent into the main heat exchanger, it is first sent into the heat exchange pipe of the condensing heat exchange device so that the flue gas in the condensing shell can preheat the cold water.

[0003] During this process, water vapor in the flue gas is condensed to form condensate, which continuously accumulates at the bottom of the condenser shell. One commonly used method for condensate treatment is to install an atomizing device at the bottom of the condenser shell. The atomizing device atomizes the condensate into fine water particles, which are then discharged outdoors from the exhaust shell. The atomizing device includes an atomizing shell and an atomizing unit located at the bottom of the atomizing shell. In actual use, it has been found that when hot flue gas enters the condenser shell through the inlet, the hot flue gas directly blows away the root of the mist generated by the atomizing unit, reducing the amount of mist. Moreover, the hot flue gas also generates misting pressure at the outlet of the atomizing shell. Both of these factors reduce the discharge of condensate mist, resulting in poor mist removal efficiency. Utility Model Content

[0004] One of the technical problems solved by this utility model is to provide a condensate treatment device that can increase the discharge of condensate atomized water mist and improve the mist removal effect.

[0005] The second technical problem solved by this utility model is to provide a condensing gas water heater that can promptly discharge the condensate generated during operation.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] Condensate treatment device, including:

[0008] A condenser housing, wherein the condenser housing is provided with a first smoke inlet;

[0009] An atomizing housing is provided with a mist outlet at the upper end and a water inlet at the lower end of the atomizing housing. The mist outlet and the water inlet are respectively connected to the condenser housing.

[0010] An atomizing unit is located at the bottom of the atomizing housing;

[0011] The first exhaust duct has its upper end connected to the outside atmosphere, and its lower end has a second smoke inlet located inside the condenser shell. The second smoke inlet is spaced above the mist outlet.

[0013] The condensate treatment device of this utility model has the following advantages compared with the prior art:

[0014] The condensate treatment device provided by this utility model atomizes the condensate in the condensation shell into water mist using an atomizing unit. The water mist is discharged from the mist outlet and flows upward. Since the first guide member is located above the atomizing shell, it guides the hot flue gas in the condensation shell into the second flue gas inlet in an upward direction. This reduces the downward atomizing pressure exerted by the hot flue gas between the second flue gas inlet and the mist outlet on the mist outlet of the atomizing shell, thus improving the atomizing effect. Moreover, the upward direction of the hot flue gas entering the second flue gas inlet facilitates the hot flue gas carrying the water mist discharged from the mist outlet into the first exhaust pipe and then into the outside atmosphere. This avoids the hot flue gas blowing the water mist flowing out of the mist outlet horizontally, causing the hot flue gas to disperse the water mist from the base of the water mist, thus improving the mist removal effect.

[0026] Multiple guide vanes are disposed on the top surface of the second guide body. The multiple guide vanes are arranged at intervals along the circumference of the second guide body. The surface of the guide vane facing away from the central axis of the mist guiding channel forms the first guide surface.

[0027] In one embodiment, the surface of the guide plate facing the central axis of the mist guiding channel forms a second mist guiding surface, which gradually approaches the central axis of the first exhaust pipe in an upward direction.

[0028] In one embodiment, the condensate treatment device further includes a second exhaust pipe sleeved outside the first exhaust pipe and forming an exhaust channel with the first exhaust pipe, and a second guide member connected to the lower end of the first exhaust pipe and spaced above the first guide member. The lower end of the exhaust channel is connected to the condensate shell, and the upper end of the exhaust channel is connected to the outside atmosphere.

[0029] The inner circumferential surface at the lower end of the second guide member is formed with a second guide surface, which gradually approaches the central axis of the first exhaust pipe in a direction from bottom to top.

[0030] In one embodiment, the first guiding surface is an arc surface or an inclined plane;

[0031] And / or, the second guiding surface is an arc surface or an inclined plane.

[0032] In one embodiment, the first flow guide is integrally formed on the atomizing housing;

[0033] Alternatively, the first flow guide and the atomizing shell are separately configured and fixedly connected;

[0034] Alternatively, the second guide element is integrally formed into the first smoke exhaust duct;

[0035] Alternatively, the second guide element and the first exhaust pipe are separately configured and fixedly connected.

[0036] In one embodiment, the first guide member has a first sidewall and a second sidewall disposed opposite to each other along the X direction. The first sidewall is located between the second sidewall and the first smoke inlet along the X direction.

[0040] The condensing gas water heater provided by this utility model includes the aforementioned condensate treatment device. The atomizing unit atomizes the condensate in the condensing shell into water mist, which is discharged from the mist outlet and flows upward. Since the first guide member is located above the atomizing shell, it guides the hot flue gas in the condensing shell to enter the second flue gas inlet in an upward direction. This reduces the downward atomizing pressure formed by the hot flue gas between the second flue gas inlet and the mist outlet on the mist outlet of the atomizing shell, thus improving the atomizing effect. Moreover, the upward direction of the hot flue gas in the condensing shell into the second flue gas inlet facilitates the hot flue gas to carry the water mist discharged from the mist outlet into the first exhaust pipe and discharge it into the outside atmosphere. This avoids the hot flue gas blowing the water mist flowing out of the mist outlet horizontally, causing the hot flue gas to disperse the water mist from the root of the water mist, thus improving the mist discharge effect. This allows the condensate generated during the operation of the condensing gas water heater to be discharged in a timely manner through the condensate treatment device. Attached Figure Description

[0062] like Figure 1 As shown, an embodiment of this utility model provides a condensate treatment device and a gas water heater. The gas water heater includes a condensate treatment device, a main heat exchanger, a burner for heating the water flowing within the main heat exchanger, a fan for supplying air to the burner, and a gas inlet pipe connected to the gas inlet of the burner. A gas control valve is installed on the gas inlet pipe. A hot water outlet pipe is connected to the hot water outlet of the main heat exchanger, and a cold water inlet pipe is connected to the cold water inlet of the main heat exchanger. Cold water enters the main heat exchanger through the cold water inlet pipe. When the gas control valve opens, gas is sent to the burner through the gas inlet pipe. Simultaneously, the fan operates to send air to the burner. The burner heats the cold water flowing within the heat exchanger to form hot water, which flows out through the hot water outlet pipe. Exemplarily, the gas control valve is a proportional valve used to regulate the gas flow rate.

[0063] The condensate treatment device includes a condenser shell 11 and condenser heat exchange tubes 12. Both ends of the condenser heat exchange tubes 12 extend out of the condenser shell 11. The outlet end of the condenser heat exchange tubes 12 is connected to the inlet end of the main heat exchanger, and the outlet end of the condenser heat exchange tubes 12 is connected to a cold water inlet pipe. A first flue gas inlet 111 is provided on the condenser shell 11. The air outlet of the fan is connected to the first flue gas inlet 111. A first exhaust pipe 3 is connected to the condenser shell 11. The upper end of the first exhaust pipe 3 is open to the outside atmosphere, and the lower end of the first exhaust pipe 3 forms a second flue gas inlet 30 located inside the condenser shell 11. For example, the condenser heat exchange tubes 12 are coil structures, utilizing the coil structure to absorb waste heat from the hot flue gas, thereby improving the heat exchange efficiency between the hot flue gas and the cold water inside the condenser heat exchange tubes 12.

[0064] The high-temperature flue gas generated by combustion is cooled by the main heat exchanger and then sent into the condenser shell 11 by a fan. Low-temperature water enters the condenser heat exchange tube 12 through the cold water inlet pipe. The low-temperature water in the condenser heat exchange tube 12 exchanges heat with the hot flue gas in the condenser shell 11, thereby preheating the water in the condenser heat exchange tube 12. The heated water in the condenser heat exchange tube 12 then enters the main heat exchanger for further heating, so as to make full use of the heat in the flue gas and improve the heat exchange efficiency. After the flue gas in the condenser shell 11 is cooled, it enters the first exhaust pipe 3 through the second flue gas inlet 30 and is discharged into the outside atmosphere through the first exhaust pipe 3.

[0065] The condensate treatment device also includes an atomizing housing 21 and an atomizing unit 22. The atomizing unit 22 is located at the bottom of the atomizing housing 21. The upper end of the atomizing housing 21 is provided with a mist outlet 212, and the lower end of the atomizing housing 21 is provided with a water inlet 211. The water inlet 211 and the mist outlet 212 are respectively connected to the condensate housing 11. The second flue gas inlet 30 is arranged at intervals above the mist outlet 212.

[0066] The condensate treatment device also includes a first guide member 4, which is disposed above the atomizing housing 21. The first guide member 4 is used to guide the flue gas in the condensing housing 11 to flow obliquely upward into the second flue gas inlet 30.

[0067] The condensate in the condenser housing 11 enters the atomizing housing 21 and is atomized by the atomizing unit 22 to form water mist. The water mist is discharged from the mist outlet 212 and flows upward. Since the first guide member 4 is set above the atomizing housing 21, during the process of the flue gas in the condenser housing 11 entering the second flue gas inlet 30, the first guide member 4 guides the hot flue gas in the condenser housing 11 to enter the second flue gas inlet 30 in an oblique upward direction. This can reduce the downward atomizing pressure formed by the hot flue gas entering the second flue gas inlet 30 and the mist outlet 212 on the mist outlet 212 of the atomizing housing 21, thereby improving the atomizing effect. Moreover, the hot flue gas in the condenser housing 11 enters the second flue gas inlet 30 in an oblique upward direction, which is conducive to the hot flue gas carrying the water mist discharged from the mist outlet 212 into the first exhaust pipe 3 and being discharged into the outside atmosphere. This avoids the hot flue gas blowing the water mist flowing out of the mist outlet 212 horizontally, causing the hot flue gas to disperse the water mist from the root of the water mist, thereby improving the mist exhaust effect.

[0068] Specifically, the circumferential sidewall of the first guide member 4 is connected to the upper end of the atomizing housing 21 and is disposed around the outer periphery of the mist outlet 212; the first guide member 4 is provided with a first guide surface on both side walls in the X direction, so that the hot flue gas flows out more evenly from the opposite side walls of the first guide member 4, wherein the X direction is perpendicular to the vertical direction.

[0069] In some embodiments, such as Figures 1 to 3 As shown, the circumferential sidewall of the first guide member 4 is spaced apart from the inner wall of the condenser shell 11. The first smoke inlet 111 and the first guide member 4 are spaced apart along the X direction. The first guide member 4 has a first guide surface 421 on both sides of the first guide member 4 in the X direction. The first guide surface 421 gradually approaches the central axis of the first exhaust pipe 3 in the direction from bottom to top.

[0070] Furthermore, the first guide member 4 is a rectangular ring structure. The first guide member 4 includes a first sidewall 411 and a second sidewall 412 that are opposite to each other and spaced apart along the X direction, and two third sidewalls 413 that are opposite to each other along the Y direction. The first sidewall 411 and the second sidewall 412 are connected by the two third sidewalls 413, and the X direction, Y direction and vertical direction are perpendicular to each other. The first sidewall 411 is located between the second sidewall 412 and the first smoke inlet 111 along the X direction, and a first guide surface 421 is provided on both the first sidewall 411 and the second sidewall 412.

[0071] The first guide element 4 is spaced apart from the inner wall of the condenser shell 11. Hot flue gas is present around the first guide element 4. When the hot flue gas flows to the vicinity of the first guide element 4, a portion of the hot flue gas enters the first exhaust duct 3 on the side where the first side wall 411 is located, and another portion of the hot flue gas enters between the third side wall 413 and the inner wall of the condenser shell 11. A small amount of hot flue gas between the third side wall 413 and the inner wall of the condenser shell 11 enters the first exhaust duct 3 through the third side wall 413. A large amount of hot flue gas between the inner walls of the condenser shell 11 enters the space between the second side wall 412 and the inner wall of the condenser shell 11, and enters the first exhaust pipe 3 on the side where the second side wall 412 is located. This means that the hot flue gas mainly enters the first exhaust pipe 3 from the side where the first side wall 411 is located and the side where the second side wall 412 is located. The first side wall 411 and the second side wall 412 are both provided with a first guide surface 421, which can guide the hot flue gas to flow obliquely upward into the first exhaust pipe 3 by the first guide surface 421.

[0072] In some embodiments, such as Figure 3 As shown, the first guide member 4 has a mist guiding channel 410, and the mist outlet 212 is connected to the second smoke inlet 30 through the mist guiding channel 410; the first guide member 4 is provided with a smoke inlet channel 414, one end of the smoke inlet channel 414 extends to the outer peripheral wall of the first guide member 4, and the other end of the smoke inlet channel 414 is connected to the mist guiding channel 410, and the inner wall of the smoke inlet channel 414 forms a first guide surface 421.

[0073] Specifically, such as Figure 3 As shown, the first guide member 4 includes a first guide body 41a and a smoke guide part 42. The lower end of the first guide body 41a is connected to the atomizing shell 21, and the mist guide channel 410 is disposed on the first guide body 41a. The smoke guide part 42 protrudes from the inner wall of the mist guide channel 410 and is provided with a smoke guide channel 4142. The inner wall of the mist guide channel 410 is provided with a smoke inlet 4141 that extends to the outer wall of the first guide body 41a. One end of the smoke guide channel 4142 extends to the upper surface of the smoke guide part 42, and the other end of the smoke guide channel 4142 is connected to the smoke inlet 4141 to form a smoke inlet channel 414.

[0074] When the hot flue gas flows to the vicinity of the first guide member 4, the hot flue gas will enter the smoke guide channel 4142 through the flue gas inlet 4141. Since the first guide surface 421 gradually approaches the central axis of the first exhaust pipe 3 from bottom to top, the first guide surface 421 will guide the hot flue gas to flow obliquely upward into the mist guide channel 410. The hot flue gas entering the mist guide channel 410 flows obliquely upward and drives the water mist in the mist guide channel 410 to flow upward. This can significantly reduce the downward misting pressure formed by the hot flue gas entering the mist guide channel 410 on the mist outlet 212, reduce the impact of the hot flue gas on the misting amount of the atomizing unit 22, and the hot flue gas entering the mist guide channel 410 will not blow horizontally directly into the water mist in the mist guide channel 410. This is conducive to the hot flue gas driving the water mist in the mist guide channel 410 to flow upward, so that the water mist in the mist guide channel 410 can smoothly enter the first exhaust pipe 3 and be discharged, ensuring the misting effect.

[0075] Specifically, such as Figure 3 As shown, the first sidewall 411 and the second sidewall 412 of the first guide member 4 are each provided with a plurality of smoke guides 42 arranged at intervals along the Y direction. The smoke guides 42 correspond one-to-one with the flue gas inlet 4141 so as to send sufficient hot flue gas into the mist guide channel 410 through the smoke inlet channel 414.

[0076] For example, three smoke guide sections 42 are provided on each of the first sidewall 411 and the second sidewall 412. It should be noted that one, two, four or more smoke guide sections 42 may also be provided on each of the first sidewall 411 and the second sidewall 412. When one smoke guide section 42 is provided on each of the first sidewall 411 and the second sidewall 412, the smoke guide section adopts a long strip structure extending in the Y direction, so as to open a sufficiently large smoke guide channel 4142, so that a sufficient amount of hot flue gas can enter the mist guide channel 410 through the smoke inlet channel 414.

[0077] exist Figure 3 In the embodiment shown, the flue gas inlet 4141 is a rectangular hole, such as... Figure 4 In the illustrated embodiment, the flue gas inlet 4141 is a circular opening. The flue gas inlet 4141 can also be an elliptical opening or other shapes that facilitate airflow.

[0078] In some embodiments, such as Figure 3 As shown, the smoke guide section 42 includes two side plates spaced apart along the Y direction, and an arc-shaped guide plate connected between the two side plates. The upward-facing side of the arc-shaped guide plate forms the first guide surface 421, which is an arc-shaped surface.

[0079] In some embodiments, such as Figure 3As shown, a first mist-guiding surface 422 is formed on the outer peripheral wall of the smoke guide section 42, and the first mist-guiding surface 422 gradually approaches the central axis of the first exhaust duct 3 from bottom to top. By setting the first mist-guiding surface 422, the condensation phenomenon that occurs when water mist collides with the smoke guide section 42 during its ascent is reduced.

[0080] For example, such as Figure 3 As shown, the arc-shaped guide plate forms the first mist guiding surface 422 on the side wall of the inner wall of the mist guiding channel 410 connected to it. The first mist guiding surface 422 is an arc-shaped surface.

[0081] In other embodiments, such as Figure 4 As shown, the smoke guide section 42 includes a spherical shell with an open top, and the spherical shell is connected to the flue gas inlet 4141 on one side in the X direction. The inner wall of the spherical shell forms the aforementioned first guide surface 421, which is an arc-shaped surface. The first guide surface 421 increases the smoothness of smoke delivery and guides the hot flue gas. The outer wall of the spherical shell forms the aforementioned first mist guide surface 422, which is also an arc-shaped surface.

[0082] In other embodiments, the first guide member 4 may adopt a rectangular ring structure, and the smoke inlet channel 414 may be set as an inclined hole. The central axis of the inclined hole is set at an angle to the central axis of the mist guiding channel 410, and the inclined hole gradually approaches the central axis of the mist guiding channel 410 in the direction from bottom to top. At this time, the hot flue gas will flow obliquely upward into the mist guiding channel 410 under the guiding effect of the inner wall of the inclined hole.

[0083] In some embodiments, such as Figure 3 As shown, the third sidewall 413 is connected to the first sidewall 411 on one side in the X direction via a first chamfered surface, and the third sidewall 413 is connected to the second sidewall 412 on the other side in the X direction via a second chamfered surface. The first and second chamfered surfaces guide the hot flue gas, which helps to guide the hot flue gas from the side where the first sidewall 411 is located to the side where the second sidewall 412 is located.

[0084] In some embodiments, such as Figures 5 to 7As shown, the first guide member 4 is vertically spaced from the first exhaust pipe 3. While the first guide member 4 is configured with an inlet channel 414, its vertical arrangement with the first exhaust pipe 3 allows the hot flue gas entering the mist guiding channel 410 through the inlet channel 414 to flow upwards. This guides the hot flue gas directly entering the space between the first guide member 4 and the first exhaust pipe 3, causing this portion of the hot flue gas to also flow obliquely upwards. This prevents the hot flue gas directly entering the space between the first guide member 4 and the first exhaust pipe 3 from dispersing the water mist, reducing the mist-forming pressure exerted by the hot flue gas directly entering the space between the first guide member 4 and the first exhaust pipe 3 on the water mist below. Furthermore, the vertical arrangement of the first guide member 4 with the first exhaust pipe 3 increases the amount of hot flue gas entering the first exhaust pipe 3, which is beneficial for the hot flue gas to carry the water mist discharged from the mist outlet 212 into the first exhaust pipe 3.

[0085] In other embodiments, such as Figure 8 and Figure 9 As shown, the outer peripheral surface of the upper end of the first guide member 4 forms a first guide surface 421. When the hot flue gas in the condenser shell 11 comes into contact with the first guide surface 421, the first guide surface 421 will guide the hot flue gas through the gap between the first guide member 4 and the first exhaust pipe 3 and enter the upper first exhaust pipe 3.

[0086] Specifically, the first guide member 4 includes a second guide body 41b connected to the top of the atomizing housing 21, and a plurality of guide plates 43 disposed on the top surface of the second guide body 41b. The plurality of guide plates 43 are arranged at intervals along the circumference of the second guide body 41b. The second guide body 41b is provided with a mist guiding channel 410. The mist outlet 212 is connected to the second smoke inlet 30 through the mist guiding channel 410. The surface of the guide plate 43 facing away from the central axis of the mist guiding channel 410 forms a first guide surface 421, which is an inclined plane. The surface of the guide plate 43 facing the central axis of the mist guiding channel 410 forms a second mist guiding surface 431, which is also an inclined plane.

[0087] like Figure 8 and Figure 9 As shown, the lower edge of the second mist guiding surface 431 is connected to the inner wall of the mist guiding channel 410, so that the second mist guiding surface 431 is located directly above the mist outlet 212. The second mist guiding surface 431 is used to guide the water mist flowing upward from the mist guiding channel 410, reducing the possibility of condensation due to collision with the second mist guiding surface 431 during the rising process of the water mist.

[0088] For example, four guide vanes 43 are provided, and the four guide vanes 43 are arranged sequentially at intervals along the circumference of the second guide body 41b. The second guide body 41b is a rectangular ring structure. The second guide body 41b has two first walls arranged opposite to each other along the X direction and two second walls arranged opposite to each other along the Y direction. Each of the upper edges of the two first walls is connected to a guide vane 43, and each of the upper edges of the two second walls is connected to a guide vane 43.

[0089] It should be noted that a guide vane 43 can also be provided, which adopts a conical structure. The outer circumferential surface of the conical structure forms the first guide surface 421, and the inner circumferential surface of the conical structure forms the second mist guide surface 431.

[0090] In some embodiments, such as Figure 4 As shown, the outer peripheral surface of the first guide member 4 forms a barrier. In order to reduce the amount of hot flue gas entering the first exhaust duct 3 from the side where the first side wall 411 is located and increase the amount of hot flue gas entering the first exhaust duct 3 from the side where the second side wall 412 is located, in some embodiments, the vertical distance between the top surface of the first side wall 411 and the first exhaust duct 3 is smaller than the vertical distance between the top surface of the second side wall 412 and the first exhaust duct 3. By increasing the vertical distance between the second sidewall 412 and the first exhaust pipe 3, the amount of hot flue gas entering the first exhaust pipe 3 from the side where the second sidewall 412 is located is increased. This prevents water mist from condensing due to collisions between the hot flue gas and the sidewall of the first exhaust pipe 3 on the side where the second sidewall 412 is located when the amount of hot flue gas entering the first exhaust pipe 3 from the side where the first sidewall 411 is located is too large. This improves the uniformity of hot flue gas entering the second smoke inlet 30 from all directions and ensures the uniformity of the smoke flow rate entering the mist exhaust channel through the mist outlet 212.

[0091] For example, the height of the top surface of the third sidewall 413 gradually decreases from the first sidewall 411 to the second sidewall 412.

[0092] In some embodiments, such as Figure 1 and Figure 2 As shown, the first guide element 4 and the atomizing housing 21 are separately configured and fixedly connected, as follows: Figure 6 In the illustrated embodiment, the lower end of the first flow guide body 41a and the atomizing shell 21 are inserted into each other with an interference fit. In other embodiments, the first flow guide body 41a and the atomizing shell 21 can be integrally formed. Figure 8 In the illustrated embodiment, the lower end of the second flow guide body 41b and the atomizing shell 21 are inserted into each other with an interference fit. In other embodiments, the second flow guide body 41b and the atomizing shell 21 may be integrally formed.

[0093] In some embodiments, such as Figure 8As shown, the condensate treatment device also includes a second exhaust pipe 6, which is sleeved outside the first exhaust pipe 3 and forms an exhaust channel 100 with the first exhaust pipe 3. The lower end of the exhaust channel 100 is connected to the condenser shell 11, and the upper end of the exhaust channel 100 is connected to the outside atmosphere. For example, the second smoke inlet 30 is located directly above the mist outlet 212.

[0094] The water mist flowing out of the mist outlet 212 is driven by the hot flue gas and enters the first exhaust pipe 3 through the second smoke inlet 30, and is discharged into the outside atmosphere through the first exhaust pipe 3; part of the hot flue gas in the condenser shell 11 enters the exhaust channel 100 and is discharged into the outside atmosphere through the exhaust channel 100. The hot flue gas in the exhaust channel 100 is used to insulate the first exhaust pipe 3, increase the inner wall temperature of the first exhaust pipe 3, reduce the recondensation of water mist on the inner wall of the first exhaust pipe 3, and improve the mist removal effect.

[0095] In some embodiments, the lower end face of the first exhaust duct 3 is lower than the lower end face of the second exhaust duct 6. This arrangement prevents the water mist flowing out of the mist outlet 212 from being blown horizontally away when hot flue gas enters the exhaust channel 100, thus preventing the hot flue gas from being blown away from the base of the water mist and forming a clump.

[0096] In some embodiments, such as Figure 8 and Figure 9 As shown, the condensate treatment device also includes a second guide member 5 disposed at the lower end of the first exhaust pipe 3 and spaced above the first guide member 4; the inner circumferential surface of the lower end of the second guide member 5 includes a second guide surface 51, and the second guide surface 51 gradually approaches the central axis of the first exhaust pipe 3 in a direction from bottom to top.

[0097] The second guide surface 51 is used to make the hot flue gas that enters the first exhaust pipe 3 between the first guide member 4 and the second guide member 5 flow in an upward direction, so as to avoid the hot flue gas that enters the second smoke inlet 30 through the gap between the first guide member 4 and the second guide member 5 blowing the water mist directly and dispersing the water mist.

[0098] For example, the second guide surface 51 is an inclined plane. In other embodiments, the second guide surface 51 may also be an arc surface.

[0099] In some embodiments, such as Figure 8 and Figure 9 As shown, the second guide member 5 and the first exhaust pipe 3 are separately configured but fixedly connected. For example, the upper end of the second guide member 5 and the first exhaust pipe 3 are inserted into each other with an interference fit. In other embodiments, the second guide member 5 and the first exhaust pipe 3 can also be integrally formed.

[0100] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0101] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
