Description
Technical field
The present invention relates to the gas heater technical field, particularly a kind of condensation high-efficiency gas water heater.
Background technology
Along with the continuous development of science and technology, the improvement day by day of people's living standard, the demand of hot water in people's daily life increases greatly, and water heater, gas heater are extensive use of by people, and especially gas displacement type water heater has been come into huge numbers of families gradually.
In the time of common gas water heater working, can give off a large amount of flue gases, temperature is up to 180 ℃, common water heater can't utilize this part heat, is slatterned in vain, simultaneously, in the process of discharging up to 180 ℃ of high-temperature flue gas, heat transmission makes fuselage obviously hot, touches with hand, can't stop on fuselage.And the key of condensation technology is the high-efficiency condensation heat exchanger, the cold water pipe that advances of water heater is close to condensing heat exchanger, when the high-temperature flue gas of discharging passes through condensing heat exchanger, the overwhelming majority heats heat exchanger that is condensed absorbs, in order to the cold water in the preheating water inlet pipe, be equivalent to before general gas water heater heating cold water, carry out once heating in advance, it should be noted that the heat in order to preheating cold water is not to obtain by combustion gas, but utilized heat in the irretrievable flue gas originally, thereby reach energy-saving effect, have environmental protection concurrently, the flue-gas temperature of so final discharge has only about 60 ℃, when being delivered to fuselage again, temperature is existing to be reduced, touch with hand, have only the sensation of temperature slightly, hand can rest on the fuselage fully.
Yet condensing type water heater be owing to need utilize latent heat in the flue gas, thereby will inevitably reduce exhaust gas temperature, thereby can produce condensed water, and acidic gas in flue gas can be dissolved in condensed water, thereby forms acid condensate water.Therefore, adopt the condensed type combustion gas water heater of indirect heat exchange mode that two technical problems that are different from common water heater are arranged: one is the generation and the emission problem of acid condensate water; Another is exactly the etching problem on acid condensate water heat exchanging device surface.
The condensed water that produces by the heat exchange smoke pipe in the existing condensing type water heater heating process inevitably drips downwards/flows along heat exchange smoke pipe inwall, and the heat exchange smoke pipe is arranged at the burner top usually, and high-temperature flue gas is discharged after upwards absorbing heat exchange by a heat exchange smoke pipe on the water tank central vertical axis.Water with fixed attention with corrosiveness can drip on burner and the combustion flame, and condensed water has corrosiveness to burner, and finally causes combustion conditions variation, reduction flame temperature, reduces the thermal efficiency then.
Therefore, how to avoid having of the corrosion of the condensed water of corrosiveness, and improve heat exchange efficiency, become the important technological problems that those skilled in the art need to be resolved hurrily burner.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of condensation high-efficiency gas water heater, avoid having of the corrosion of the condensed water of corrosiveness, and improve heat exchange efficiency burner.
For achieving the above object, the invention provides following technical scheme:
A kind of condensation high-efficiency gas water heater, comprise water tank, be arranged at the burner of described water tank downside, heat-insulation layer and the shell that is arranged at the described water tank outside and has the enclosure in smoke evacuation gap, vertically run through the heat exchange smoke pipe of described water tank and be coated on the described enclosure outside with described water tank, described enclosure has the exhaust outlet that communicates with atmosphere, described heat exchange smoke pipe is at least two, and its end that is positioned at described water tank bottom is avoided the position of described burner.
Preferably, in above-mentioned condensation high-efficiency gas water heater, described enclosure specifically comprises:
Be positioned at the fluid dividing cover at top, form the shunting chamber between the top of described fluid dividing cover and described water tank;
Be positioned at described fluid dividing cover downside, and the condensation cover that is connected with described fluid dividing cover, forming condensation chamber between the sidewall of described condensation cover and described water tank, described condensation chamber is connected with described shunting chamber.
Preferably, in above-mentioned condensation high-efficiency gas water heater, described enclosure also comprises the backflow cover that is arranged at described heat-insulation layer bottom, forms back cavity between described backflow cover and the described condensation cover, and described back cavity is connected with described exhaust outlet and described condensation chamber respectively.
Preferably, in above-mentioned condensation high-efficiency gas water heater, has the projection of extending on the described fluid dividing cover to described heat exchange smoke pipe.
Preferably, in above-mentioned condensation high-efficiency gas water heater, described heat exchange smoke pipe be arranged in uniformly described burner around.
Preferably, in above-mentioned condensation high-efficiency gas water heater, described heat exchange smoke pipe is three.
From above-mentioned technical scheme as can be seen, condensation high-efficiency gas water heater provided by the invention has changed the position distribution of heat exchange smoke pipe, the center smoke pipe on the cancellation water tank vertical centering control axis, increased the heat exchange smoke pipe more than two or two, its position distribution requires to avoid the position of described burner.The condensed water that produces by the heat exchange smoke pipe in the condensation high-efficiency gas water heater heating process inevitably drips downwards/flows along heat exchange smoke pipe inwall, the present invention is by having changed the position of heat exchange smoke pipe, get around burner and combustion flame, guaranteed that condensed water can not drip on burner and the combustion flame again.Fundamentally solved the corrosion of condensed water, the combustion conditions variation that causes by condensed water, reduced the problem of flame temperature and energy, improved the thermal efficiency burner.
