Description

The heat exchanger of condenser boiler
Technical field
The invention relates to the heat exchanger of condenser boiler, be exactly in more detail, the side and the opposite side that relate at sensible heat portion heat exchanger are provided with, one convexes with blast pipe and the exchange of the 1st sensible heat with it loop lid and the 2nd sensible heat exchange loop lid, because latent heat portion heat exchanger is arranged on the bottom of above-mentioned sensible heat portion's heat exchanger and blast pipe, reduced heat exchanger shared area in boiler to greatest extent, can make the product form the heat exchanger of compactness, lightweight condenser boiler.
Technical background
In general, in home-use Lukewarm water boiler, gas boiler with ignition transformer by main burner light by gas supply pipe for coal gas, and heat-exchange device is set, by supplying water and steam heating pipe is provided with attic tank and warm water circulating pump etc.Heat-exchange device herein be a kind of allow the different fluid of temperature in the heat transfer plate intermediate flow, make the contained heat of high temperature fluid pass to the device of cryogen.
But the thermal efficiency of common gas boiler only has an appointment 75%～80%, and remaining 20%～25% has lost with the discharge of waste gas.Thereby one of method that reclaims this waste gas institute heat content is exactly the condensation heat exchange technology, thus promptly on the passage that above-mentioned waste gas is discharged, regenerative heat exchanger is set, with the waste gas condensation with its heat recovery, it is minimum that heat loss is dropped to.
Fig. 1 is the perspective view of heat exchanger with common condenser boiler of sensible heat portion and latent heat portion.As shown in the figure, adopted the heat exchanger that can improve the dual structure of the thermal efficiency in the former condenser boiler, this structure is owing to the latent heat portion heat exchanger 2 of the sensible heat portion heat exchanger 1 on top and bottom is used as integrated, utilized the waste gas of discharging to be discharged into the energy of outside loss, can expect conserve energy with gas boiler.
At first, the sensible heat portion heat exchanger 1 on above-mentioned top absorbs the burning sensible heat that burner 8 produces, but this sensible heat portion heat exchanger 1 be welded on up and down by soldering configuration sensible heat exchange pipe 9 around, at the sensible heat exchange column 3 and the internal flow heat transfer medium that absorb sensible heat, and constitute by the sensible heat exchange pipe 9 that the sensible heat exchange column 3 from the outside absorbs the heat transferred heat transfer mediums, in addition, use the soldering processing and manufacturing.
The condensation latent heat that the latent heat portion heat exchanger 2 of above-mentioned bottom produces when being absorbed in remaining sensible heat after heat exchange is finished in the above-mentioned sensible heat portion heat exchanger 1 and condensation, this latent heat portion heat exchanger 2 be welded on up and down by soldering configuration latent heat exchange pipe 10 around, at the latent heat exchange column 4 and the internal flow heat transfer medium that absorb latent heat, and absorb the latent heat exchange pipe 10 that latent heat pass to heat transfer medium by the latent heat exchange column 4 from the outside and constitute, use the stainless steel processing and manufacturing.
Therefore, the heat exchanger of the duplex that condenser boiler is in the past used is the device that a kind of combustion heat that produces when absorbing burner combustion passes to heat transfer medium then, constitute by the latent heat portion heat exchanger 2 of the sensible heat portion heat exchanger 1 on top and bottom is dual, the sensible heat portion heat exchanger 1 that absorbs sensible heat is made of copper to guarantee only pyroconductivity and thermal absorptivity, and the latent heat portion heat exchanger 2 usefulness stainless steels that absorb latent heat are made to guarantee the corrosion resistance for corrosive deposits such as sulfur oxide contained in condensed water and the burnt gas composition, nitrogen oxides.The top coiling of above-mentioned sensible heat portion heat exchanger 1 has copper combustion chamber sensible heat exchange pipe 5.
Fig. 2 is the integrally-built structure chart of the common condenser boiler of explanation.As shown in the figure, as Fig. 1, by the latent heat portion heat exchanger 2 dual condensate and heat exchangers that constitute of the sensible heat portion heat exchanger 1 on top and bottom by burning with gas and air by burner 8, the blower motor 7 of only burning condition mixing after-combustion and supply with the required combustion air of burning and heat exchange structure figure that waste gas that the back of will burn the produces air blast 6 outside being discharged to is connected.Secondly, the combustion chamber 11 coiling combuster sensible heat exchange pipes 5 between burner device 8 and the sensible heat portion heat exchanger 1, said burner 8 is provided with jet for gas 12 flows into coal gas.
In addition, the gas discharge outlet for can combustion gas that has of above-mentioned latent heat portion heat exchanger 2 bottoms one side is connected with the blast pipe 13 that establish in addition above-mentioned heat exchanger outside.
Secondly, the bottom face of above-mentioned latent heat portion heat exchanger 2 with carry out the condensed water that produces in the heat exchanging process in the above-mentioned latent heat portion heat exchanger 2 and the hood of establishing in addition is connected in order to be collected in.
But, in the heat exchanger of the condenser boiler before constituting as previously mentioned, for the fluid of inside forms pipeline so that the latent heat exchange pipe that has on the sensible heat exchange pipe 9 that has on the above-mentioned sensible heat portion heat exchanger 1 and the above-mentioned latent heat portion heat exchanger 2 10 goes out and syndeton to outside Local Convex, thus because of the loss of cool air that contacted the outside heat, therefore have the heat exchanger problem of heat-shift effectively that hinders.
In addition, above-mentioned blast pipe 13 is connected with the gas discharge outlet for can combustion gas that is positioned at that above-mentioned latent heat portion heat exchanger 2 bottoms one side has, because this blast pipe is located at the outside of heat exchanger in addition, therefore exist and make heat exchanger area occupied in boiler increase the problem that hinders home-use boiler densification.
Secondly, in order to collect the condensed water that produces in the heat exchanging process, above-mentioned hood 14 is located at the bottom face of above-mentioned latent heat portion heat exchanger 2 in addition, owing to existing parts to produce elsewhere to make manufacturing cost to rise and being assembled into parts elsewhere and the problem of making troubles to production line, there is the problem that hinders productivity (raising) in the result.
In other words, the heat exchanger of foregoing boiler in the past can not be made product small-sized, light and that the thermal efficiency is high.
Summary of the invention
