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 widely used 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 on fuselage, stop.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 through combustion gas; But utilized the heat in the irretrievable flue gas of script; 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.
Heat exchange smoke pipe one end of present condensing type water heater communicates with the shunting chamber at top, flows into the flue gas in the shunting chamber by up heat exchange smoke pipe, is flowed down by descending heat exchange smoke pipe and discharges through exhaust outlet.Condensing type water heater is owing to be atmospheric combustion, and flue gas belongs to nature and flows, and therefore a large amount of flue gases blocks up in the shunting chamber, has reduced heat exchange efficiency.
In addition, condensing type water heater be owing to need utilize the 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 through 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 through a heat exchange smoke pipe on the water tank central vertical axis.Condensed water 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.
