Burn in device and burnt, produce high-temperature flue gas；High-temperature flue gas flow through heat exchanger, and heating circulation water is passed through in heat exchanger to high temperature
Flue gas heat absorbs, while heating circulation water is heated.
High-temperature flue gas by heat exchanger cooling after by smoke exhaust pipe discharge, flue-gas temperature still between 120~200 DEG C, then
Amount of heat is discharged in flue gas, causes the waste of fuel gas calorie.Flue gas is cold despite the provision of for some gas-heating water heaters
Solidifying heat exchanger, but because structure setting is unreasonable, have a strong impact on the heat energy transformation efficiency of gas-heating water heater.
Meanwhile, because the temperature of flue gas is higher, during smoke evacuation, blower fan is influenceed equally be greatly reduced by high temperature to be used
Life-span.
In current known technology, temperature can be reduced after high-temperature flue gas heat exchange, condensed water occur, then accumulate in heat exchanger
On.Because the condensed water on heat exchanger cannot be derived in time, heat exchanger will be corroded, and cause structure to be destroyed, and influence is just
Normal service life.
As CN201392113Y discloses the waste heat and recovery of latent heat device of a kind of gas-heating water heater, the device connects
Water pond uses monoblock type drip tray, and on the one hand such structure design causes the flue gas can only to be flowed from burner side, causes cold
Solidifying heat exchanger is uneven with smoke contacts, influences its transformation efficiency；On the other hand, the condensate that condensing heat exchanger is produced can be from one
The flue gas inlet port of side is dropped onto on the heat exchanger of lower section, due to having dissolved the sour gas in flue gas in the condensate of drippage, is led
Causing condensate has stronger corrosivity, destroys heat exchanger structure performance.
Therefore, how to design a kind of brand-new device to improve heat exchange efficiency, and solve to be discharged in time because of condensed water
The problem that the heat exchanger for causing is damaged by corrosion, is those skilled in the art's urgent need to resolve.

Specific embodiment：
This programme is described in detail below in conjunction with accompanying drawing.
Embodiment 1：A kind of gas-heating water heater fume afterheat condensate recycling device, its structure as shown in figure 1, including：
Housing 9；The heat exchanger 2 of First Heat Exchanger 4 and second vertically is provided with the housing 9, the top of housing 9 is provided with smoke evacuation
Pipe 1；
The bottom of housing 1 is provided with burner 5；
Several water receiving tanks 3, the two ends of any water receiving tank 3 are provided between the heat exchanger 2 of the First Heat Exchanger 5 and second
It is respectively equipped with water-accepting board long and short water-accepting board, the projection of the water-accepting board long on adjacent water receiving tank 3 is by a part for short water-accepting board
Covering；
And it is provided with gap between adjacent water receiving tank 3；
Wherein, the high-temperature flue gas that the combustion gas of burner 3 are produced are after the heat exchange of First Heat Exchanger 4 between water receiving tank 3
Gap flows up and carries out secondary heat exchange through the second heat exchanger 2, and the condensed water produced after secondary heat exchange derives shell by water receiving tank 3
Outside body 3.
According to the actual requirements, water receiving tank 3 may be selected to be V-type or be W types.
In order to further improve water receiving effect, water receiving tank 3 be arranged in parallel with the second heat exchanger 2.
First Heat Exchanger 4 may be selected to be copper tube and fin heat exchanger.
Gas control valve 7 is provided with burner 3, the gas control valve 7 is controlled by central controller 8.
Second heat exchanger 4 is flue gas condensing heat exchanger, and the spacing of fin is 4mm in the middle of the flue gas condensing heat exchanger,
With heat exchange efficiency higher.
With reference to shown in Fig. 1 and Fig. 2：Combustion gas enters from air inlet pipe 6, and central controller 8 controls the aperture of gas control valve 7,
Complete the regulation of gas flow.Combustion gas is burnt after entering through burner 3, produces high-temperature flue gas 10, high-temperature flue gas 10 to flow up,
After being exchanged heat through First Heat Exchanger 4, temperature is reduced to 120-200 DEG C, and the flue gas after once exchanging heat continues up flowing, in water receiving tank
Deflecting in gap between 3, becomes the second heat exchanger of smoke contacts 2 backward, realizes secondary heat exchange.
With reference to shown in Fig. 3, condensed water 11 can be produced after secondary heat exchange, because having incorporated sour gas in the middle of condensed water 11,
So with corrosivity higher.Condensed water 11 is dripped downwards, can be dropped into water receiving tank 3.Because the two ends difference of water receiving tank 3
With water-accepting board long and the less short water-accepting board of sectional area that a sectional area is larger, the orthographic projection of water-accepting board long is by short water-accepting board
Part covering, using the principle of water droplet vertical drop, no matter water droplet is dropped on which water receiving tank 3, will not be from adjacent
Flowed downward out in gap between water receiving tank 3, then all water receiving tanks 3 cooperate and can just catch all of condensed water, condensed
Water 11 would not be dropped on First Heat Exchanger 4, cause First Heat Exchanger 4 to damage.
For the ease of the water conservancy diversion of condensed water 11, the equal tiltable of all of water receiving tank 3 is set, the relatively low one end of water receiving tank 3 with lead
Flow tube (not shown) is connected, and the other end of mozzle is stretched out in outside housing 1, and condensed water 11 is derived.
After employing said structure, the present apparatus has two heat exchangers, and heat exchange efficiency higher, two are just provided with accordingly
Flue-gas temperature reduction after secondary heat exchange, will not cause too much influence to blower fan；Condensed water after secondary heat exchange is connect by water receiving tank
Outside is firmly guided to be damaged caused by preventing heat exchanger because condensing aqueous corrosion.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or uses the present invention.
