Description
Technical field
The utility model relates to a kind of gas heater, especially a kind of flue gas condensing formula gas heater.
Background technology
Now, along with China's rapid development of economy, energy problem becomes increasingly conspicuous.Develop the meaning of simple gas instantaneous water heater, bring up to the strategic height that realizes sustainable economic development from simple for saving expenditure.Contain a large amount of SO in the flue gas of gas heater at present
2, NO
XDeng sour gas, atmosphere is caused very big pollution, and the thermal efficiency can't improve substantially again.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of flue gas condensing formula gas heater, and this flue gas condensing formula gas heater can effectively reduce the SO in the flue gas
2, NO
XThe discharging and the raising thermal efficiency, and simple in structure, reliable.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of flue gas condensing formula gas heater, be provided with condensate and heat exchanger, condensate and heat exchanger is mainly by housing, the condensate pipe group, gas baffle and smoke deflector are formed, the top of condensate and heat exchanger is provided with the water heater exhaust opening, be provided with the condensate pipe group in the housing, the top, combustion chamber is the sensible heat heat exchanger, condensate and heat exchanger is in the sensible heat heat exchanger top of (being used for domestic water), gas baffle is in the housing top of condensate and heat exchanger, be the lower housing portion that oblique smoke deflector is in the condensation heat exchange hydrophone, the condensate pipe group is closed in gas baffle, in the space between housing and the smoke deflector, leave first gap (for cooling back exhanst gas outlet) between gas baffle one end and housing one inboard, leave second gap (for smoke inlet) between another relative inner of smoke deflector and housing, smoke deflector is higher than its other end away from second gap near an end in second gap, condensate pipe group water inlet in the condensate and heat exchanger connects running water, condensate pipe group delivery port in the condensate and heat exchanger communicates with sensible heat heat exchanger water inlet, sensible heat heat exchanger delivery port meets the user, condensate and heat exchanger can make full use of a large amount of latent heat in flue gas and the steam like this, makes the thermal efficiency of water heater improve about 12%.
Further technical scheme of the present utility model is: condensation heat exchange utensil two-way heat exchange circulation.
The beneficial effects of the utility model are: flue gas enters condensate and heat exchanger from second gap behind the sensible heat heat exchanger carries out heat exchange and (forms condensed water, SO the condensate and heat exchanger simultaneously
2, NO
XBe dissolved in the condensed water Deng sour gas), cooling back flue gas comes out to discharge by exhaust opening from first gap, and exhaust gas temperature is reduced near dew point or below the dew point, can effectively reduce the exhaust emission of flue gas.Condensate and heat exchanger makes full use of a large amount of latent heat of flue gas and steam simultaneously, can make the thermal efficiency of water heater improve about 12%, and the utility model is simple in structure, reliable.

The specific embodiment
Embodiment: a kind of flue gas condensing formula gas heater, be provided with condensate and heat exchanger 1, condensate and heat exchanger is mainly by housing, condensate pipe group 2, gas baffle 3 and smoke deflector 4 are formed, the top of condensate and heat exchanger is provided with water heater exhaust opening 5, be provided with the condensate pipe group in the housing, the top, combustion chamber is the sensible heat heat exchanger, condensate and heat exchanger is in the sensible heat heat exchanger top of (being used for domestic water), gas baffle is in the housing top of condensate and heat exchanger, be the lower housing portion that oblique smoke deflector is in the condensation heat exchange hydrophone, the condensate pipe group is closed in gas baffle, in the space between housing and the smoke deflector, leave first gap 11 (for cooling back exhanst gas outlet) between gas baffle one end and housing one inboard, leave second gap 12 (for smoke inlet) between another relative inner of smoke deflector and housing, smoke deflector is higher than its other end away from second gap near an end in second gap, condensate pipe group water inlet in the condensate and heat exchanger connects running water, condensate pipe group delivery port in the condensate and heat exchanger communicates with sensible heat heat exchanger water inlet, sensible heat heat exchanger delivery port meets the user, condensate and heat exchanger can make full use of a large amount of latent heat in flue gas and the steam like this, makes the thermal efficiency of water heater improve about 12%.
Condensation heat exchange utensil two-way heat exchange circulation.
The structure of this flue gas condensing formula gas heater adopts the flue gas flow guiding type.The material of condensate and heat exchanger is a stainless steel.
Operation principle is:
The combustion chamber is in the bottom of water heater, and high-temperature flue gas flows into sensible heat heat exchanger (being domestic water) from the combustion chamber, and after the sensible heat heat exchanger absorbed most of heat, in the outlet of sensible heat heat exchanger, flue-gas temperature was reduced to 200-250 ℃ approximately; Low-temperature flue gas flow to condensate and heat exchanger through second gap again through smoke deflector, upwards heat exchange takes place in flue gas that flows and the heat exchanger tube in the condensate and heat exchanger (Guan Zhongwei is without the cold water of crossing heat exchange), flue-gas temperature drops to dew-point temperature, discharge by flue by first gap, air deflector again, flow into the sensible heat heat exchanger again after cold water enters from condensate and heat exchanger simultaneously, cold water in the condensate and heat exchanger obtains flowing into the sensible heat heat exchanger again after the heat exchange like this, can make the thermal efficiency of water heater improve about 12%; In condensate and heat exchanger, condensate liquid accumulates in the bottom again, flows out from the condensate liquid conduit at last, enters foul water system again through after the neutralisation treatment.Condensate pipe group in the condensate and heat exchanger adopts corrugated stainless steel tubing, and structure does not have heat absorbing sheet, be difficult for knot carbon, and the stainless steel acid corrosion-resistant is very strong.
