Description
Technical field
The utility model relates to a kind of heat exchanger that is used for condensed type combustion gas water heater.
Background technology
Be becoming tight energy day now, particularly under fossil fuel situation in short supply day by day, condensed type combustion gas water heater is owing to being paid attention to widely more than 12% than the general gas water heater thermal efficiency is high, existing many at present companies release condensed type combustion gas water heater, generally all be to carry out twice heat exchange by heat-exchange system, after flue gas that burning produces is through a heat exchange, its temperature reduces, after through heat exchange for the second time, temperature is reduced to below the flue gas dew point temperature, steam in the flue gas will be condensed into water, discharges latent heat.But, the condensed type combustion gas water heater of having reported adopts integration production, when improving the thermal efficiency and energy-saving effect, paid huger economy input, and the integration design makes condensing type water heater bring numerous inconvenience aspect R and M, also can bring certain potential safety hazard because of the corrosion of afterheat heat exchanger in the long-term process of using.
The utility model content
The purpose of this utility model is, at existing common condensed type combustion gas water heater input cost height, safeguard inconvenience and have deficiency such as potential safety hazard, a kind of heat exchanger that is used for condensed type combustion gas water heater is provided, adopt thermal siphon to utilize the waste heat of flue gas, when not additional additional energy source consumes, the waste heat of flue gas is made full use of, reach the effect of energy savings.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of heat exchanger that is used for condensed type combustion gas water heater comprises smoke chamber, heat-exchanging chamber, some thermal siphons; Heat-exchanging chamber is positioned at the smoke chamber top; Smoke chamber is provided with gas approach and exhanst gas outlet; Heat-exchanging chamber is provided with water inlet and delivery port; Described some thermal siphons (abbreviation heat pipe) are vertical array, and the part of thermal siphon places heat-exchanging chamber (for the thermal siphon cooling section), and another part places smoke chamber (for the thermal siphon bringing-up section).
Described smoke chamber bottom is provided with the condensed water delivery port.
Described thermal siphon is equipped with some fins being positioned on the smoke chamber part, to increase heat exchange area.
The utility model adopts hot pipe technique to collect in the smoke evacuation temperature difference sensible heat and the steam latent heat of vaporization of condensing, and is used for the preheating water temperature, guarantees the gas heater safe and reliable operation simultaneously, has characteristics such as cost is low, simple in structure, applied widely.
Description of drawings
Fig. 1 is heat exchanger and the condensed type combustion gas water heater installation system structural representation that the utility model is used for condensed type combustion gas water heater;
Fig. 2 is the heat converter structure schematic perspective view that the utility model is used for condensed type combustion gas water heater.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Embodiment:
As shown in Figure 2, be used for the heat exchanger of condensed type combustion gas water heater, comprise smoke chamber 1, heat-exchanging chamber 2, some thermal siphons 3; Heat-exchanging chamber is positioned at the smoke chamber top; Smoke chamber is provided with gas approach 4 and exhanst gas outlet 5; Heat-exchanging chamber is provided with water inlet 6 and delivery port 7; Described some thermal siphons are vertical array, and the cooling section of thermal siphon places heat-exchanging chamber, and the bringing-up section of thermal siphon places smoke chamber.Described smoke chamber bottom is provided with condensed water delivery port 8.Described thermal siphon is equipped with some fins 9 on bringing-up section (being positioned at the flue gas indoor section), to increase heat exchange area.
In Fig. 1, the gas approach 4 of smoke chamber that the utility model is used for the heat exchanger of condensed type combustion gas water heater connects the smoke exhaust pipe of condensed type combustion gas water heaters 10, heat-exchanging chamber water inlet 6 water receiving sources, and delivery port 7 connects condensed type combustion gas water heater water inlet pipe.Usually, the flue of exhanst gas outlet 5 need slightly be inclined upwardly, to allow a small amount of condensate return collect discharge to smoke chamber.
Heat pipe is closed conduct or the system that inside vacuumized and charged into certain quantity of fluid, and an end of pipe is evaporator section (bringing-up section), and the other end is condensation segment (cooling section), can arrange heat insulation layer (being called the adiabatic section) according to application need two sections centres.Liquid carburation by evaporation when an end of heat pipe is heated in the capillary wick, liquid carburation by evaporation when steam flows to the other end and is heated under small pressure reduction in the capillary wick, steam flows to the other end and emits heat and condense into liquid under small pressure reduction, liquid flows back to evaporator section along porous material by the effect of capillary force again.So circulate endlessly, heat reaches the other end by an end of heat pipe.
Therefore, heat pipe has following structure and heat compensator conducting property:
1) inside heat pipe is vaporization and the phase-change heat-exchange that condenses, and thermal resistance is very little, so that heat pipe has high axial thermal conductivity ability or an axial temperature is even, therefore is called as high-performance heat transfer components or superconduction thermal element.
2) the cold and hot side liquid that participates in heat exchange all flows outside heat pipe, and fluid flow resistance is little, and is easy to fin and realizes heat conduction reinforced.
3) adopting heat pipes for heat transfer has passed through wall twice, does not have seepage, and thermal source and low-temperature receiver fluid mix anything but mutually.
When 4) inside heat pipe had the imbibition core, heat transfer can automatically reversely be carried out, and can adapt to the heat exchange needs of Various Seasonal and heat transfer temperature difference.
Heat-transfer capability is big, heat transfer temperature difference is little, flow resistance is low because heat pipe has, reverse heat transfer, do not have features such as the remote layout of seepage, Cooling and Heat Source, so be used for technical solutions of the utility model, good effect of heat exchange.
The course of work of the present utility model is:
The high-temperature flue gas that fuel gas buring produces is by behind the main heat exchanger of gas heater, enter smoke chamber 1 by smoke exhaust pipe, carry out heat exchange with thermal siphon 3, thermal siphon 3 is used for the heat that absorbs to the cold water preheating in the heat-exchanging chamber by cooling section, thereby reach the effect of recovery waste heat, whole device makes the thermal efficiency improve more than 12%.Flue gas by heat pipe after the condensed water of condensation can absorb the NO of part in the flue gas
xAnd SO
x, to discharge by condensed water delivery port 8, the flue gas after lowering the temperature like this can directly enter the air from flue, can play effect such as prevent the pollution of the environment.
