Description

The condensed type combustion gas water heater heat-exchanger rig
Technical field: the present invention relates to a kind of condensed type combustion gas water heater heat-exchanger rig, it is adapted to condensed type combustion gas water heater and condensed type combustion gas heating hot water stove.
Background technology: condensed type combustion gas water heater of the prior art generally is to carry out twice heat exchange by two groups of heat-exchange systems, makes full use of the thermal efficiency that latent heat in the high-temperature flue gas reduces the temperature of flue gas and improves water heater.And the high-temperature flue gas that burning produces is through producing condensed water behind the secondary heat exchange, common condensed type combustion gas water heater is to be provided with the water spilage tray of collecting condensed water on a heat exchanger, but common condensed type combustion gas water heater is when the condensed water discharging is not smooth, water heater is still in running order, thereby condensed water can overflow the condensed water water spilage tray to flow on heat exchanger and the burner, and these all are the major hidden dangers of damaging the water heater internals.For overcoming these defectives, the condensed type combustion gas water heater heat-exchanger rig is developed.
Summary of the invention: technical problem to be solved in the utility model is that a kind of condensed type combustion gas water heater heat-exchanger rig will be provided, it can prevent the phenomenon that the condensed water discharging does not freely cause condensed water to overflow water spilage tray, the damage of avoiding condensed water that the water heater internals is brought effectively.
The technical scheme that the present invention solves its technical problem employing is: it comprises sensible heat exchanger, smoke gas collecting apparatus, condensing heat exchanger, the condenser water spilage tray, condenser water spilage tray smoke inlet, condenser water spilage tray fume emission mouth, condensing heat exchanger and condenser water spilage tray are positioned at the sensible heat exchanger top, condensing heat exchanger is positioned at condenser water spilage tray inner and upper, the smoke inlet of smoke gas collecting apparatus is connected with sensible heat exchanger, the exhanst gas outlet of smoke gas collecting apparatus is connected with condensed water water spilage tray smoke inlet, the top that it is characterized in that described condenser water spilage tray is provided with baffle plate, described baffle plate is between condenser water spilage tray fume emission mouth and condenser water spilage tray smoke inlet, and the lower end of described baffle plate is lower than the lower end of condenser water spilage tray smoke inlet.
Described baffle plate is divided condensing heat exchanger equally and is left and right sides two parts.
Described condenser water spilage tray fume emission mouth is positioned at the top of condensing heat exchanger.
Described condenser water spilage tray smoke inlet is positioned at the top or a upper lateral part of condenser water spilage tray.
Described condensing heat exchanger is made of the above metal bellows of two-way.
Described metal bellows is a corrugated stainless steel tubing.
The present invention compares the beneficial effect that is produced with background technology: because the utility model is provided with baffle plate at condensed water water spilage tray top, and the lower end of baffle plate is lower than the lower end of condenser water spilage tray smoke inlet, therefore it can make water heater quit work before condensed water overflows water spilage tray, had solved effectively that condensed water overflows water spilage tray and the problem of the damage water heater internals that causes.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an explosive view of the present utility model.
Fig. 3 is the explosive view of smoke gas collecting apparatus 2 among Fig. 2, condensing heat exchanger 3, condenser water spilage tray smoke inlet 5, baffle plate 7, metal bellows 9.
The specific embodiment: referring to accompanying drawing 1, accompanying drawing 2, shown in the accompanying drawing 3, present embodiment comprises sensible heat exchanger 1, smoke gas collecting apparatus 2, condensing heat exchanger 3, condenser water spilage tray 4, condenser water spilage tray smoke inlet 5, condenser water spilage tray fume emission mouth 6, condensing heat exchanger 3 and condenser water spilage tray 4 are positioned at sensible heat exchanger 1 top, condensing heat exchanger 3 is positioned at condenser water spilage tray 4 inner and upper, condensate drain outlet 8 is in the bottom of condenser water spilage tray 4 one sides, the smoke inlet of smoke gas collecting apparatus 2 links to each other with the top of sensible heat exchanger 1, its exhanst gas outlet links to each other with condenser water spilage tray smoke inlet 5, baffle plate 7 is between condenser water spilage tray fume emission mouth 6 and condenser water spilage tray smoke inlet 5, and by welding, riveted joint or screw are fixed on the top of condenser water spilage tray 4, condenser water spilage tray smoke inlet 5 is positioned at the top or a upper lateral part (right part shown in Fig. 1) of condenser water spilage tray 4, condenser water spilage tray fume emission mouth 6 is positioned at the top of condensing heat exchanger 3, the lower end of baffle plate 7 is lower than the lower end of smoke inlet 5, when baffle plate 7 is divided equally condensing heat exchanger 3 for left and right sides two parts, flue gas enters condenser water spilage tray 4 from condenser water spilage tray smoke inlet 5, it is last by 6 discharges of condenser water spilage tray fume emission mouth to walk around baffle plate 7 then, because flue gas successively carries out heat exchange by the condensing heat exchanger of two equalizations, make heat exchange area reach maximum, thereby heat exchange efficiency is the highest.
Condensing heat exchanger 3 is made of the above corrugated stainless steel tubing 9 of two-way, one road corrugated stainless steel tubing 9 is made up of a water inlet pipe and an outlet pipe, present embodiment is totally 6 road corrugated stainless steel tubings 9, corrugated stainless steel tubing 9 can prevent acid condensate water heat exchanging equipment matter and corrosion effectively, improves service life; The above corrugated stainless steel tubing 9 of two-way can improve heat exchange efficiency, reduces condensation vessel volume.
The implementation process of Fig. 1: during the water heater operate as normal, high-temperature flue gas is at first reduced to about 150 ℃ by temperature after sensible heat exchanger 1 heat exchange, enter condenser water spilage tray 4 through smoke gas collecting apparatus 2 from condenser water spilage tray smoke inlet 5 then, again with condensing heat exchanger 3 heat exchange after temperature reduce to below 90 ℃, producing condensed water with condensing heat exchanger 3 contact surfaces, flue gas is discharged from condenser water spilage tray fume emission mouth 6, and condensed water is discharged from condensate drain outlet 8 after condenser water spilage tray 4 is collected.
In entire work process, the formed condensed water in cooling back is all in condenser water spilage tray 4, because high-temperature flue gas enters in the condenser water spilage tray 4 by smoke gas collecting apparatus 2, make high-temperature flue gas directly not contact and produce condensed water with the cold wall of condensed water water spilage tray, thereby the condensing drip of avoiding producing and then influences the operate as normal of water heater on sensible heat exchanger 1.
When condensate drain outlet 8 is blocked, the water level of condensed water constantly raises, because the lower end of condenser water spilage tray smoke inlet 5 is higher than the lower end of baffle plate 7, when condensed water rises to the lower end of baffle plate 7, this moment since flue gas can't discharge and force water heater to quit work, thereby can not produce condensed water again, guarantee that condensed water can not flow on smoke gas collecting apparatus 2 and the sensible heat exchanger 1 from smoke inlet 5, avoid condensed water to overflow water spilage tray corrosion sensible heat exchanger 1.
