Description

TECHNICAL FIELD

[0001] The utility model relates to water heater technical field especially relates to a condensate atomizing device and condensing gas water heater. BACKGROUND

[0002] The working principle of the condensing gas water heater is that the flue gas after heat exchange and temperature reduction by the main heat exchanger is sent into the condensing shell of the condensing heat exchange device, and the cold water is sent into the heat exchange pipeline of the condensing heat exchange device before being sent into the main heat exchanger, so as to preheat the cold water by the flue gas in the condensing shell.

[0003] In this process, the water vapor in the flue gas is condensed to form condensate water, which continuously accumulates at the bottom of the condensing shell. One of the commonly used condensate water treatment methods is to set an atomizing device at the bottom of the condensing shell, which includes an atomizing shell and an atomizing unit arranged at the bottom of the atomizing shell. The atomizing shell above the atomizing unit is formed with an out-mist passage. An out-mist pipe is arranged at the top of the condensing shell. The inlet mist port at the lower end of the out-mist pipe is arranged above the out-mist port at the top of the out-mist passage. The interval between the inlet mist port and the out-mist port forms an inlet smoke port. After the condensate water is atomized by the atomizing device to form water mist, the water mist flows out of the out-mist passage and directly enters the out-mist pipe above. The hot flue gas in the condensing shell enters the out-mist pipe through the inlet smoke port and drives the water mist in the out-mist pipe to be discharged.

[0004] In actual application, it is found that as the condensate water level in the condensing shell gradually rises and is higher than the out-mist port, the opening degree of the inlet smoke port gradually decreases. The root of the water mist also gradually rises to the inlet smoke port along with the condensate water level, so that the hot flue gas blows the water mist from the root of the water mist into clusters, reducing the mist forming effect and thus reducing the amount of mist formed. At the same time, the opening degree of the inlet smoke port gradually decreases, and the smoke pressure at the inlet smoke port increases, resulting in an increase in the pressure at the root of the water mist, thus reducing the amount of mist formed. Both of them will reduce the discharge of the condensate water mist, resulting in poor mist discharge effect. UTILITY MODEL CONTENTS

[0052] Condensate atomizing device includes condensing shell 11 and condensing heat exchange pipe 12, both ends of condensing heat exchange pipe 12 are out of condensing shell 11, the outlet end of condensing heat exchange pipe 12 is connected with the inlet end of main heat exchanger, and the outlet end of condensing heat exchange pipe 12 is connected to cold water inlet pipe.Condensing shell 11 is provided with smoke inlet 111, the air outlet of fan and smoke inlet are communicated, and condensing shell 11 is connected with exhaust pipe.Exemplarily, condensing heat exchange pipe 12 is coil pipe structure, which absorbs waste heat in hot flue gas, to improve the heat exchange efficiency between cold water in condensing heat exchange pipe 12 and hot flue gas.

[0053] The high-temperature flue gas generated by combustion is sent into the condensing shell 11 through a fan after being cooled by the main heat exchanger, and the low-temperature water enters the condensing heat exchange pipe 12 through the cold water inlet pipe. The low-temperature water in the condensing heat exchange pipe 12 exchanges heat with the hot flue gas in the condensing shell 11, thereby preheating the water in the condensing heat exchange pipe 12, and the water in the condensing heat exchange pipe 12 is further heated in the main heat exchanger. The flue gas in the condensing shell 11 is discharged to the outside atmosphere through the flue gas discharge pipe after being cooled. The condensation water atomization device can fully utilize the heat in the flue gas and improve the heat exchange efficiency.

[0054] The condensation water atomization device further comprises an atomization shell 21, an atomization unit 22 and a first mist discharge pipeline 3. The upper end of the atomization shell 21 is formed with a mist outlet 210, and the lower end of the atomization shell 21 is provided with a water inlet. The mist outlet 210 and the water inlet are respectively communicated with the condensing shell 11, and the atomization unit is arranged at the bottom of the atomization shell 21. One end of the first mist discharge pipeline 3 is communicated with the outside atmosphere, and the other end is formed with a mist inlet 30 located in the condensing shell 11. The mist inlet 30 is arranged above the mist outlet 210.

[0055] The condensation water atomization device further comprises a second mist discharge pipeline 41. The second mist discharge pipeline 41 can ascend and descend along with the condensation water level in the condensing shell 11 to move the air inlet hole 411 between the mist outlet 210 and the mist inlet 30. The mist outlet 210 is communicated with the mist inlet 30 through the second mist discharge pipeline 41. The sidewall of the second mist discharge pipeline 41 is provided with an air inlet hole 411. The flue gas inlet is communicated with the mist inlet 30 through the air inlet hole 411.

[0056] The condensation water in the condensing shell 11 enters the atomization shell 21 through the water inlet, is atomized by the atomization unit 22 at the bottom of the atomization shell 21 to form water mist, and flows upward into the second mist discharge pipeline 41 through the mist outlet 210. After the hot flue gas enters the condensing shell 11 from the flue gas inlet, it enters the second mist discharge pipeline 41 through the air inlet hole 411. The hot flue gas in the second mist discharge pipeline 41 drives the water mist to enter the first mist discharge pipeline 3 through the mist inlet 30, and is discharged to the outside atmosphere through the first mist discharge pipeline 3.

[0057] When the condensate water level in the condensing shell 11 rises, the second mist discharging pipe 41 follows the rise of the condensate water level, so that the height of the air inlet hole 411 is synchronously raised, avoiding the condensate water level being higher than the air inlet hole 411, thus making the root of the water mist always below the air inlet hole 411, so as to avoid the hot flue gas entering the second mist discharging pipe 41 through the air inlet hole 411 directly blowing the root of the water mist in the second mist discharging pipe 41 and affecting the mist forming effect, at the same time, the air inlet hole 411 moves between the mist outlet 210 and the mist inlet 30, the air inlet hole 411 is always above the condensate water level, the opening area of the air inlet hole 411 for circulating flue gas will not be reduced due to the rise of the condensate water level, so that the flue gas pressure at the air inlet hole 411 is not affected by the condensate water level, avoiding the reduction of the opening area of the air inlet hole 411 for circulating flue gas, which increases the downward pressure on the root of the water mist when the flue gas enters from the air inlet hole 411, reduces the influence on the mist forming pressure of the atomizing unit 22, thereby improving the mist forming amount, increasing the discharge of the condensate water mist, and improving the mist discharging effect.

[0058] It should be noted that, as shown in Figure 5 , in the present embodiment, the upper end of the second mist discharging pipe 41 is movably connected to the lower end of the first mist discharging pipe 3 in the up-down direction.

[0059] In other embodiments, the lower end of the second mist discharging pipe 41 is movably connected to the upper end of the atomizing shell 21 in the up-down direction, so that the air inlet hole 411 moves between the mist outlet 210 and the mist inlet 30.

[0060] In some embodiments, as shown in Figure 2 and Figure 3 , a plurality of air inlet holes 411 are arranged on the second mist discharging pipe 41 in a circumferential direction, so that the flue gas can enter the second mist discharging pipe 41 through the air inlet holes 411 in time, meeting the smoke discharging requirement, and the amount of hot flue gas entering the second mist discharging pipe 41 through the air inlet holes 411 meets the water mist discharging demand.

[0061] In some embodiments, as shown in Figure 2 and Figure 3 , the second mist discharging pipe 41 is a rectangular pipe, the condensing heat exchange pipe 12 is arranged between the second mist discharging pipe 41 and the smoke inlet 111 in the width direction of the second mist discharging pipe 41, and the four sides of the second mist discharging pipe 41 are provided with air inlet holes 411. After the hot flue gas enters the condensing shell 11 through the smoke inlet 111, it first exchanges heat with the cold water in the condensing heat exchange pipe 12, and then enters the second mist discharging pipe 41 through the air inlet hole 411.

[0062] Exemplarily, the second mist discharging pipe 41 has a first side wall and a second side wall oppositely arranged along the width direction of the second mist discharging pipe 41, and two third side walls oppositely arranged along the length direction of the second mist discharging pipe 41, the first side wall is between the second side wall and the smoke inlet 111 along the width direction of the second mist discharging pipe 41. Each of the four side walls of the second mist discharging pipe 41 is provided with an air inlet hole 411. For the convenience of description, the air inlet hole 411 on the first side wall is referred to as the first air inlet hole 411a, the air inlet hole 411 on the second side wall is referred to as the second air inlet hole 411b, and the air inlet hole 411 on the third side wall is referred to as the third air inlet hole 411c.

[0063] The four side walls of the second mist discharging pipe 41 and the inner wall of the condensing shell 11 are arranged in a spaced manner. When the hot flue gas flows to the second mist discharging pipe 41, a large amount of hot flue gas directly enters the second mist discharging pipe 41 through the first air inlet hole 411a, the residual hot flue gas enters the first gap between the third side wall and the inner wall of the condensing shell 11, a small amount of flue gas in the first gap enters the second mist discharging pipe 41 through the third air inlet hole 411c, a large amount of flue gas in the first gap enters the second gap between the second side wall and the inner wall of the condensing shell 11, and the hot flue gas in the second gap enters the second mist discharging pipe 41 through the second air inlet hole 411b. In order to reduce the flow difference of the flue gas flowing through the first air inlet hole 411a and the second air inlet hole 411b, in some embodiments, the cross-sectional area of the second air inlet hole 411b is greater than the cross-sectional area of the first air inlet hole 411a, so as to increase the amount of flue gas entering the second air inlet hole 411b.

[0064] In some embodiments, as shown in Figure 2 and Figure 3 , the two adjacent side walls of the second mist discharging pipe 41 are connected by a chamfered surface. Specifically, the first side wall and the third side wall are connected by a first chamfered surface, and the second side wall and the third side wall are connected by a second chamfered surface. The first chamfered surface and the second chamfered surface both have a flow guiding effect, so that the hot flue gas between the second mist discharging pipe 41 and the smoke inlet 111 can enter the first gap under the action of the first chamfered surface, and the hot flue gas in the first gap can enter the second gap under the flow guiding effect of the second chamfered surface. Exemplarily, the first chamfered surface and the second chamfered surface are both circular arc surfaces. As an alternative, the first chamfered surface and the second chamfered surface can also be inclined planes.

[0065] In some embodiments, as shown in Figure 2 and Figure 3 , the condensate water atomizing device further comprises a buoyancy member 42 connected to the second mist discharging pipe 41.

[0066] When the condensate water level in the condensing shell 11 rises, the buoyant member 42 is driven upward by buoyancy to raise the height of the air inlet hole 411. When the condensate water level in the condensing shell 11 falls, the second mist discharging pipe 41 can fall under the action of its own gravity to lower the height of the air inlet hole 411. The second mist discharging pipe 41 can timely follow the rise and fall of the condensate water level in the condensing shell 11, and the response is fast.

[0067] It should be noted that the above-mentioned buoyant member 42 can be selected from a foam float, a plastic float, etc., and can be selected according to the required buoyancy, which is not specifically limited here.

[0068] As an alternative, a liquid level detection unit and a driving unit can also be used to replace the above-mentioned buoyant member 42, wherein the liquid level detection unit is used to detect the condensate water level in the condensing shell 11 in real time, and the driving unit is used to control the driving unit to drive the second mist discharging pipe 41 to rise and fall in real time according to the condensate water level in the condensing shell 11. It should be noted that the liquid level detection unit can be selected from a liquid level sensor, and the driving unit can be selected from an electric push rod, an air cylinder, etc. As another alternative, the second mist discharging pipe 41 can be entirely made of a buoyant structure.

[0069] In some embodiments, as shown in Figure 3 and Figure 4 , the lower end surface of the buoyant member 42 is lower than the lower end surface of the second mist discharging pipe 41. In this way, the buoyant member 42 can timely sense the change of the condensate water level in the condensing shell 11, and the corresponding timeliness is improved.

[0070] In some embodiments, as shown in Figure 3 and Figure 4 , the second mist discharging pipe 41 and the buoyant member 42 are inserted in the up-down direction, the buoyant member 42 is provided with a mist passing channel 421 penetrating in the up-down direction, and the mist outlet 210 communicates with the second mist discharging pipe 41 through the mist passing channel 421. In this way, the setting of the buoyant member 42 does not affect the water mist entering the second mist discharging pipe 41. For example, the upper end of the buoyant member 42 is inserted into the lower end of the second mist discharging pipe 41. As an alternative, the buoyant member 42 can be fittedly sleeved outside the lower end of the second mist discharging pipe 41, or the upper end of the buoyant member 42 can be fittedly inserted into the lower end of the second mist discharging pipe 41; as another alternative, a plurality of buoyant members 42 can be used, and the plurality of buoyant members 42 are independently installed at the lower end of the second mist discharging pipe 41.

[0071] In some embodiments, as shown in Figure 2 and Figure 3As shown, the condensate atomizing device further comprises a connecting piece 43, one end of the connecting piece 43 is provided with a limiting portion 431 abutting against the buoyant piece 42, and the other end of the connecting piece 43 is clamped to the second mist discharging pipe 41 after penetrating through the buoyant piece 42. The connecting mode of the buoyant piece 42 and the second mist discharging pipe 41 is simple, and the disassembly and assembly are convenient and fast.

[0072] Specifically, the end of the connecting piece 43 away from the limiting portion 431 is provided with a plurality of elastic buckles 432, the plurality of elastic buckles 432 are arranged at intervals along the circumference of the connecting piece 43, the buoyant piece 42 is provided with a first penetrating hole, the inner wall of the second mist discharging pipe 41 is provided with a mounting protrusion 413, the mounting protrusion 413 is provided with a second penetrating hole, the upper end of the buoyant piece 42 is inserted into the second mist discharging pipe 41 from the lower end of the second mist discharging pipe 41 and abuts against the lower surface of the mounting protrusion 413, the elastic buckles 432 penetrate through the first penetrating hole and the second penetrating hole in turn and then restore the deformation, so that the buckle surface of the elastic buckles 432 abuts against the upper surface of the mounting protrusion 413, and the limiting portion 431 abuts against the lower surface of the buoyant piece 42, so as to clamp the buoyant piece 42 and the mounting protrusion 413 between the limiting portion 431 and the buckle surface of the elastic buckles 432, thereby connecting the buoyant piece 42 to the second mist discharging pipe 41.

[0073] As an alternative, the limiting portion 431 can abut against the second mist discharging pipe 41, and the other end of the connecting piece 43 is clamped to the buoyant piece 42 after penetrating through the second mist discharging pipe 41. Specifically, the elastic buckles 432 penetrate through the second penetrating hole and the first penetrating hole in turn and then restore the deformation, so that the buckle surface of the elastic buckles 432 abuts against the lower surface of the buoyant piece 42, and the limiting portion 431 abuts against the upper surface of the mounting protrusion 413.

[0074] In some embodiments, as shown in Figs. 1 and 2, Figure 2 and Figure 3 Specifically, the first penetrating hole is provided with a plurality of first penetrating holes arranged at intervals along the circumference of the buoyant piece 42, the mounting protrusion 413 is provided with a plurality of mounting protrusions 413 corresponding to the plurality of first penetrating holes one by one, and each first penetrating hole is provided with a connecting piece 43. In this way, the connection stability between the buoyant piece 42 and the second mist discharging pipe 41 can be improved.

[0075] Exemplarily, the cross section of the mist discharging channel 421 is rectangular, the cross section of the second mist discharging pipe 41 is perpendicular to the up-down direction, and the cross section of the second mist discharging pipe 41 is rectangular, and the cross section of the second mist discharging pipe 41 is perpendicular to the up-down direction. The four corners of the buoyant piece 42 are each provided with a first penetrating hole, and correspondingly, the inner wall of the second mist discharging pipe 41 is provided with mounting protrusions 413 corresponding to the first penetrating holes one by one, and each mounting protrusion 413 is provided with a second penetrating hole.

[0076] It should be noted that the cross section of the over-fogging channel 421 and the cross section of the second fogging pipe 41 are not limited to rectangular shapes, and the number of the first through holes is not limited to four.

[0077] In some embodiments, the connecting member 43 is made of a foam float, a plastic float, or the like. When the condensate level in the condensing shell 11 rises, the connecting member 43 and the buoyant member 42 jointly provide a force to lift the second fogging pipe 41, so as to ensure that the second fogging pipe 41 can timely follow the rise and fall of the liquid level in the condensing shell 11.

[0078] In some embodiments, as shown in Figures 1 to 4 one of the second fogging pipe 41 and the first fogging pipe 3 is rotatably connected with a rolling member 415, and the other is provided with a guide groove 31. The rolling member 415 is in rolling connection with the guide groove 31 in the up-down direction. In this way, the friction between the second fogging pipe 41 and the first fogging pipe 3 can be reduced, and the second fogging pipe 41 can be prevented from being stuck, thereby improving the smoothness of the lifting of the second fogging pipe 41.

[0079] Specifically, the lower end of the first fogging pipe 3 is inserted into the upper end of the second fogging pipe 41, the guide groove 31 is arranged on the outer peripheral wall of the first fogging pipe 3, the top of the second fogging pipe 41 is provided with a mounting bracket 414, the rolling member 415 is connected with a rotating shaft 416, and the two ends of the rotating shaft 416 are rotatably connected to the mounting bracket 414, so that the rolling member 415 can rotate relative to the mounting bracket 414.

[0080] As an alternative, the guide groove 31 can also be arranged on the inner wall of the second fogging pipe 41, and the rolling member 415 can be rotatably arranged on the lower end of the first fogging pipe 3. As another alternative, the upper end of the second fogging pipe 41 can be inserted into the lower end of the first fogging pipe 3. In this case, the rolling member 415 can be rotatably arranged on the top of the second fogging pipe 41, and the guide groove 31 can be arranged on the inner wall of the first fogging pipe 3. Alternatively, the rolling member 415 can be rotatably arranged on the lower end of the first fogging pipe 3, and the guide groove 31 can be arranged on the outer wall of the second fogging pipe 41.

[0081] In some embodiments, as shown in Figures 1 to 4 the first fogging pipe 3 is provided with an upper limiting member and a lower limiting member arranged opposite to each other in the up-down direction. The upper limiting member is located above the lower limiting member, and the rolling member 415 is limited between the upper limiting member and the lower limiting member in the up-down direction. The travel of the rolling member 415 is limited by the upper limiting member and the lower limiting member.

[0082] For example, the guide groove 31 has an upper inner wall and a lower inner wall arranged opposite to each other in the up-down direction. The upper inner wall forms the upper limiting member, and the lower inner wall forms the lower limiting member.

[0083] As shown in Figure 6 When there is no condensate water in the condensing shell 11 or the condensate water level in the condensing shell 11 is lower than the lower surface of the buoyant member 42, the rolling member 415 abuts against the lower limit member, and the lower end of the buoyant member 42 is inserted into the mist outlet 210. For the convenience of the following description, when the rolling member 415 abuts against the lower limit member and the condensate water level in the condensing shell 11 is flush with the lower surface of the buoyant member 42, the condensate water level in the condensing shell 11 is referred to as the lowest level.

[0084] As shown in Figure 7 When the condensate water level in the condensing shell 11 gradually rises above the lowest level, the buoyant member 42 gradually rises under the action of buoyancy and pushes the second mist discharging pipe 41 to rise.

[0085] When the condensate water level in the condensing shell 11 continues to rise, the buoyant member 42 continues to push the second mist discharging pipe 41 to rise, and the buoyant member 42 will be separated from the atomizing shell 21, and at this time the condensate water level in the condensing shell 11 is higher than the atomizing shell 21. As shown in Figure 8 The rolling member 415 abuts against the upper limit member, and the second mist discharging pipe 41 rises to the limit position and cannot continue to rise. In this process, the air inlet hole 411 is always higher than the condensate water level in the condensing shell 11.

[0086] In some embodiments, as shown in Figures 1 to 4 The outer wall of the second mist discharging pipe 41, which is provided with the air inlet hole 411, comprises a first flow guide surface 412, the first flow guide surface 412 is not higher than the air inlet hole 411, the first flow guide surface 412 is connected to the inner wall of the air inlet hole 411, and along the direction from bottom to top, the first flow guide surface 412 gradually approaches the central axis of the second mist discharging pipe 41.

[0087] The first flow guide surface 412 guides the hot flue gas around the second mist discharging pipe 41 to enter the air inlet hole 411 and flow obliquely upward into the air inlet hole 411, avoiding the hot flue gas entering the second mist discharging pipe 41 through the air inlet hole 411 directly impacting the root of the water mist in the second mist discharging pipe 41 to affect the mist forming effect, and because of the oblique upward flow of the hot flue gas entering the second mist discharging pipe 41 through the air inlet hole 411, the downward force of the hot flue gas on the water mist when the hot flue gas enters the second mist discharging pipe 41 through the air inlet hole 411 is avoided, the mist forming pressure is increased, and the influence of the hot flue gas entering the second mist discharging pipe 41 on the mist forming amount of the atomizing unit 22 is reduced.

[0088] Exemplarily, the first flow guide surface 412 is an inclined plane. Alternatively, the first flow guide surface 412 can also adopt a circular arc surface.

[0089] In some other embodiments, the inner wall of the air inlet hole 411 can also be formed with a second flow guide surface, which gradually approaches the central axis of the second mist discharging pipe 41 in the downward direction. The second flow guide surface is used to make the hot flue gas in the air inlet hole 411 flow obliquely upward into the second mist discharging pipe 41. For example, when the air inlet hole 411 is a rectangular hole, the air inlet hole 411 has a first inner wall and a second inner wall oppositely arranged in the upward-downward direction, the first inner wall is higher than the second inner wall, and the first inner wall and the second inner wall each form a second flow guide surface. The first inner wall can adopt a convex circular arc surface or an inclined plane, and the second inner wall can adopt a concave circular arc surface or an inclined plane. For example, the second mist discharging pipe 41 includes a flow guide body and a flow guide protrusion, the flow guide body has the second mist discharging pipe 41 arranged through in the upward-downward direction, and the flow guide protrusion is protruded on the inner wall of the second mist discharging pipe 41; one end of the air inlet hole 411 penetrates through the outer peripheral wall of the flow guide body, and the other end penetrates through the upper surface of the flow guide protrusion, and the inner wall of the air inlet hole 411 forms the above-mentioned second flow guide surface.

[0090] In some embodiments, as shown in Figure 4 and Figure 5 , the air inlet hole 411 is located below the smoke inlet 111, so that the hot flue gas in the condensing shell 11 first flows downward, then enters the second mist discharging pipe 41 through the air inlet hole 411, and then enters the first mist discharging pipe 3 above the second mist discharging pipe 41. The hot flue gas in the condensing shell 11 has a U-shaped overall trend, and the hot flue gas path is approximately L-shaped from the smoke inlet 111 to the air inlet hole 411. By arranging the first flow guide surface 412, the hot flue gas can be prevented from directly blowing the water mist in the second mist discharging pipe 41, and the pressure on the lower atomization unit 22 for forming the mist can also be avoided. The flow of the hot flue gas into the second mist discharging pipe 41 is optimized, the wind pressure on the mist outlet 210 is avoided, the effect of discharging the mist after the condensing water is atomized is improved, and the like.

[0091] In some embodiments, as shown in Figure 8 , the atomization unit 22 is provided with an atomization water level detection unit for detecting the liquid level in the atomization shell 21, so as to control the atomization unit 22 to work in real time according to the water level in the atomization shell 21. The atomization water level detection unit includes an atomization triggering water level detection piece and an atomization stopping water level detection piece. The atomization triggering water level detection piece is used to detect whether the water level in the atomization shell 21 reaches an atomization triggering water level for starting the atomization unit 22, and the atomization stopping water level detection piece is used to detect whether the water level in the atomization shell 21 reaches an atomization stopping water level for controlling the atomization unit 22 to stop working. The atomization triggering water level detection piece, the atomization stopping water level detection piece and the atomization unit 22 are all electrically connected to a controller of the condensing gas water heater, and the controller controls the atomization unit 22 to work according to the detection signals of the atomization triggering water level detection piece and the atomization stopping water level detection piece.

[0092] Because the mist outlet 210 at the top of the atomizing housing 21 is directly connected to the inner cavity of the condenser housing 11, the hot flue gas comes into direct contact with the water inside the atomizing housing 21. This can cause the water quality inside the atomizing housing 21 to be affected by the backflow of condensate and flue gas, resulting in the water quality inside the atomizing housing 21 becoming weakly acidic again, affecting the service life of the atomizing unit 22. Therefore, in some embodiments, an atomizing neutralization filter 23 is provided inside the atomizing housing 21 to perform real-time acid-base balance adjustment of the water quality inside the atomizing housing 21, creating a neutral atomizing water environment for the atomizing unit 22.

[0093] In some embodiments, such as Figure 1 and Figure 3 As shown, the condenser housing 11 is connected to the exhaust pipe 5. The first mist exhaust pipe 3 is inserted into and fixed to the exhaust pipe 5. An exhaust channel is formed between the first mist exhaust pipe 3 and the exhaust pipe 5. One end of the exhaust channel is connected to the inner cavity of the condenser housing 11, and the other end is connected to the outside atmosphere. A small amount of hot flue gas is discharged into the outside atmosphere through the exhaust channel. At the same time, the hot flue gas in the exhaust channel is used to insulate the first mist exhaust pipe 3, so as to prevent the water mist in the first mist exhaust pipe 3 from contacting the inner wall of the first mist exhaust pipe 3 and condensing and flowing back into the atomizing housing 21 below.

[0094] When the cross-sectional area of ​​the inner hole of the first mist exhaust pipe 3 is too large and the cross-sectional area of ​​the smoke exhaust channel is too small, the inner wall of the first mist exhaust pipe 3 may become too cold or insufficiently insulated. This causes the mist to easily condense and liquefy upon contact with the inner wall of the first mist exhaust pipe 3 and flow back downward into the atomizing shell 21, reducing the amount of mist exhaust. Conversely, when the cross-sectional area of ​​the inner hole of the first mist exhaust pipe 3 is too small and the cross-sectional area of ​​the smoke exhaust channel is too large, since the atomizing shell 21 is mainly located at the center below the first mist exhaust pipe 3, there is too little hot smoke flowing inside the first mist exhaust pipe 3. This is obviously not conducive to timely gathering and collecting the generated mist, causing the water mist to drift into the surrounding space. This makes the mist flow field more tortuous and chaotic, which is not conducive to maximizing the entry of water mist into the first mist exhaust pipe 3. The arrangement of the first guide surface 412 and the second guide surface can increase the smoothness of hot flue gas entering the second mist exhaust pipe 41, and guide the hot flue gas in the condenser shell 11 into the second mist exhaust pipe 41 in an upward direction. This can prevent the hot flue gas from blowing directly into the root of the mist, and also guide the mist. At the same time, it can avoid the formation of wind pressure obstruction in the inner cavity of the atomizing shell 21, thereby improving the mist exhaust effect after the condensate is atomized.

[0095] 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.

It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model.
