Description

A kind of condensed type combustion gas water heater
Technical field
The utility model relates to technical field of water heaters, relates to a kind of condensed type combustion gas water heater in particular.
Background technology
The condensation gas heater is compared with the general gas water heater, has increased the one-level condensing heat exchanger more, the preheating cold water through absorbing high-temperature flue gas, and the heat that utilizes the general gas water heater to drain as waste gas, the thermal efficiency improves more than 15%; Have the higher thermal efficiency than traditional gas instantaneous water heater, reach more than 96%, and in standard GB 6932-2001 " domestic gas instantaneous water heater ",, be merely more than 84% the thermal efficiency requirement of traditional gas instantaneous water heater.Adopt nertralizer that the condensed water of discharging is carried out harmless processing simultaneously, really realize energy-conserving and environment-protective.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, and 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, and soon in order to the cold water in the preheating water inlet pipe, is 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 heat in the irretrievable flue gas originally (not pipework condensation still be one-level heat exchange all be the heat that obtains through fuel gas buring), 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.At present, existing condensed type combustion gas water heater mainly contains two kinds of structures; 1, overhead: as shown in Figure 1, condensing heat exchanger 1 directly on main heat exchanger 2, has individual water-collecting tray 3 between two heat exchangers, is responsible for collecting condensed water; 2, split type: as shown in Figure 2, two heat exchangers 4,5 separate fully, and condensing heat exchanger 4 is in the left side or the right side.Wherein, the shortcoming of overhead condensation gas heater is a complex structure, and two heat exchangers are up and down and distribute, and causes body volume big, is inconvenient to install; Though it is comparatively convenient that split type condensation gas heater is installed, two heat exchangers separate fully, and it is big to take up room, and obviously is not suitable in the local narrow and small bathroom.For this reason, it is simple how to develop a kind of structure fabrication, and heat exchange efficiency is higher, and condensed type combustion gas water heater easy for installation has become the problem that people continue to solve.
Summary of the invention
The purpose of the utility model is exactly that a kind of not only structure fabrication that provides for the deficiency that solves prior art is simple, convenient for installation and maintenance, and the high condensed type combustion gas water heater of heat exchange efficiency.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of condensed type combustion gas water heater; The burner, main heat exchanger and the condensing heat exchanger that comprise housing and interior setting thereof; It is characterized in that; Said main heat exchanger and condensing heat exchanger are integral structure, are ectonexine and distribute, and are provided with dividing plate between main heat exchanger and the condensing heat exchanger.
As further specifying of such scheme, said dividing plate is provided with the outward flanging hole, can prevent that the condensation segment condensation flow from becoming owner of heat exchanging segment; And from top to bottom increase gradually, be uniformly distributed with air-flow, can enhanced heat exchange; The high-temperature flue gas that burning back produces through behind the deflector to around flow out; Carry out a heat exchange with the internal layer pipeline, the aperture that the high-temperature flue gas after the heat exchange passes on the dividing plate gets into the heat exchanger skin, carries out the time condensation heat exchange.
Said main heat exchanger and condensing heat exchanger are respectively to spiral and are arranged at the heat exchanging pipe of enclosure interior, and this heat exchanging pipe is set to one or more layers.
The heat exchanging pipe of said main heat exchanger and condensing heat exchanger is arranged in around the burner, and the burner flame top is provided with heat-insulating shield.
The below of said main heat exchanger and condensing heat exchanger is provided with condensate collector, is connected with condensate pipe on the condensate collector, condensed water is collected through the condensate collector around the bottom at the condensed water that outer condensing heat-exchange produces, and discharges then.
Said condensate collector is and the integrated water-accepting board that is positioned at the below of main heat exchanger and condensing heat exchanger of housing that water-accepting board is curved.
Be provided with exhaust gases passes between said condensing heat exchanger and the housing.
The top of said housing is provided with outlet flue, and this outlet flue is communicated with the exhaust gases passes that is provided with between condensing heat exchanger and the housing.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model main heat exchanger and condensing heat exchanger adopt integral type, adopt dividing plate to separate between main heat exchanger and the condensing heat exchanger, the high-temperature flue gas that the burning back produces through behind the deflector to around flow out, carry out a heat exchange with the internal layer pipeline; The aperture that high-temperature flue gas after the heat exchange passes on the dividing plate gets into the heat exchanger skin, carries out the time condensation heat exchange; The space can be saved on the one hand, heat exchange function can be strengthened on the other hand, the more effective raising thermal efficiency.
2, water circuit system heat exchange state of the utility model and flue gas flow direction are just in time opposite, and cold water gets into the internal layer heat exchange more earlier at outer condensing heat-exchange; Condensed water in that outer condensing heat-exchange produces is collected condensed water through the condensate collector around the bottom; Discharge then, compact conformation, rationally distributed.
