Specific embodiment
Below with reference to embodiment, the present invention will be further described, but is not limited to the content on specification.
The invention discloses a kind of smoke discharging structure, including backwind tube 10 and smoke exhaust pipe 20, smoke evacuation is provided in backwind tube 10
Pipe 20；Discharge flue 21 is formed inside smoke exhaust pipe 20, and return air channel 11, row are formed between 20 outer wall of 10 inner wall of backwind tube and smoke exhaust pipe
Flue gas is by the air preheat in return air channel 11 in cigarette channel 21.The present invention is by being arranged backwind tube 10 and smoke exhaust pipe, and return air
It is provided with smoke exhaust pipe 20 in pipe 10, unit is while flue gas enters smoke exhaust pipe 20 and is discharged after combustion, and external air is from return air
Pipe 10 enters in unit, at this point, fresh air is heated by high-temperature flue gas, the fresh air of low temperature enters burning system after being heated
System is discharged to outdoor by connector after high-temperature flue gas is cooled, to reduce heat loss, reduces exhaust gas temperature, improves the thermal efficiency.
Due to whether being in normal operating conditions come detection blower fan, air duct using blast switch or wind pressure sensor.Wind pressure
Switch is connected to the pressure tappings of blower by wind pressure hose, working properly to determine whether by detecting the variation of pressure difference.So
And contain vapor since the combustion characteristics of wall-hung boiler determines, in the flue gas after fuel gas buring, vapor is blended in flue gas,
Pressure difference is transmitted by wind pressure hose.Since the outside air temperature of cold winter sucking is low, Cryogenic air is blown higher in temperature
Wind pressure hose on, vapor will in wind pressure hose condensation generate condensed water, with the lengthening for using the time, condensed water meeting
Constantly accumulation, final condensed water will lead to the blocking of wind pressure hose, so that the wind pressure such as blast switch detecting element can not detect wind pressure,
Wall-hung boiler is caused to can not work normally.

In the above-described embodiments, the first end of backwind tube 10 is the air outlet of return air channel 11, the second end of backwind tube 10
For closed end, the air inlet of return air channel 11 is provided on the side wall of 10 second end of backwind tube.The first end of smoke exhaust pipe 20 be into
Mouth, the second end of smoke exhaust pipe 20 are smoke outlet, and the second end of smoke exhaust pipe 20 runs through the second end of backwind tube 10.By by return air
The air inlet in channel 11 is arranged on the side wall of 10 second end of backwind tube, can be inhaled into return air channel to avoid high-temperature flue gas,
To improve safety and reliability.
In the above-described embodiments, smoke discharging structure further includes connector 70, and connector 70 is arranged in the second end of smoke exhaust pipe 20, connector
70 for extending smoke exhaust pipe 20, and connector 70 and 20 junction of smoke exhaust pipe are provided with sealing ring.It can be extended by the way that connector 70 is arranged
Smoke exhaust pipe 20 further prevents flue gas resorption, to improve safety and reliability, sealing effect is can be improved in the setting of sealing ring
Fruit prevents flue gas from revealing.
In embodiment as shown in Figure 3, smoke exhaust pipe 20 be it is multiple, multiple smoke exhaust pipes 20 are arranged at intervals in backwind tube 10
Portion.Heat exchange area can be improved by the way that multiple smoke exhaust pipes 20 are arranged, improve heat exchange efficiency.
In the above-described embodiments, multiple baffle plates 12 are arranged at intervals in return air channel 11, multiple formation of baffle plate 12 are drawn
Lead the baffling channel of return air stream.Direct current channel is formed by setting baffle plate, the return air distance of return air stream can be made to extend,
It is that the waste heat in high-temperature flue gas can make full use of to sufficiently exchange heat with smoke exhaust pipe, improves utilization rate of waste heat.
In the above-described embodiments, the both ends of backwind tube 10 are closed end, are provided with back on the side wall of 10 first end of backwind tube
The air outlet in wind channel 11 is provided with the air inlet of return air channel 11 on the side wall of 10 second end of backwind tube.State smoke exhaust pipe 20
Both ends extend through the both ends of backwind tube 10 and extend to the outside of backwind tube 10, and the first end of smoke exhaust pipe 20 is smoke inlet, row
The second end of smoke pipe 20 is smoke outlet.By above-mentioned set-up mode, can be inhaled into return air channel to avoid high-temperature flue gas, thus
Improve safety and reliability.
In the above-described embodiments, smoke discharging structure further include: the first elbow 50 and the second elbow 60, the connection of the first elbow 50
In the first end of backwind tube 10；Second elbow 60 is connected to the first end of smoke exhaust pipe 20.
According to another aspect of the present invention, a kind of wall-hung boiler is also disclosed, including above-mentioned smoke discharging structure.
According to another aspect of the present invention, a kind of wall-hung boiler is also disclosed, including smoke discharging structure as shown in Figure 2, wall hanging
Furnace further include: wall hanging stove outer covering 30 is provided with return air inlet 31, the first end of return air inlet 31 and backwind tube 10 on wall hanging stove outer covering 30
Connection；Combustion chamber 40, combustion chamber 40 are located in wall hanging stove outer covering 30, combustion chamber 40 have smoke outlet 41, the first of smoke exhaust pipe 20
End is connected to across return air inlet 31 with smoke outlet 41.Unit is when burning operation, under the action of blower, by the high temperature cigarette after burning
Gas extraction, and be discharged by smoke exhaust pipe, due to the balance of combustion system internal pressure to be kept, inhaled from the air inlet side of return air channel
Enter fresh air, at this point, fresh air exchanges heat, the fresh air of low temperature enters combustion system, high-temperature flue gas after being heated
Outdoor is discharged to by connector after cooled.Since the flue-gas temperature of the wind pressure inside hose of detection wind pressure is higher, enter at this time
Air themperature it is also higher, by heating after, the temperature difference of the two is smaller, so that condensed water is not generated in wind pressure hose, to keep away
Unit failure problems caused by condensation water slug wind pressure hose are exempted from.
According to another aspect of the present invention, a kind of wall-hung boiler, including smoke discharging structure shown in Fig. 3 and 4, wall are also disclosed
