Along with improving constantly of people's living standard, the application of gas heater is more and more universal.The conventional common exhaust gas temperature of gas heater is higher, wherein the heat more than 10% with fume emission in atmosphere, waste heat in the flue gas can't be made full use of, and the gas heater of this routine has only utilized the sensible heat of flue gas, and the latent heat of the water vapour in the flue gas fails to utilize, with fume emission in atmosphere, so its thermal efficiency between 80~85%, and the pernicious gas in the flue gas such as COx, NOX, SOx etc. have certain pollution to environment.At this situation, some manufacturer has done a little improvement, as disclosing a kind of gas heater of double-heat exchanger among the Chinese patent literature CN1740699A, comprise total water inlet, total delivery port, water inlet pipe, outlet pipe, blower fan, combustion chamber, heat exchanger and flue, heat exchanger is arranged at the top of combustion chamber, it is characterized in that: heat exchanger is made up of sensible heat exchanger and latent heat exchanger, and latent heat exchanger places the top of sensible heat exchanger; Be provided with the flue gas recirculation passage between latent heat exchanger and the sensible heat exchanger; Total water inlet communicates with the water inlet of latent heat exchanger by water inlet pipe, and the delivery port of latent heat exchanger communicates with the water inlet of sensible heat exchanger, and the delivery port of sensible heat exchanger communicates with total delivery port by outlet pipe.Though the gas heater of this double-heat exchanger has improved the thermal efficiency to a certain extent,, its structure more complicated, cost of manufacture are than higher, and windage is bigger, the thermal efficiency is still not too high.
The utility model content
The purpose of this utility model aims to provide a kind of heat-exchanger rig of simple and reasonable, cost of manufacture is low, energy-saving effect is better, the thermal efficiency is higher condensed type combustion gas water heater, to overcome weak point of the prior art.
Press the heat-exchanger rig of a kind of condensed type combustion gas water heater of this purpose design, comprise the condensing heat exchanger and the blower fan that are arranged on main heat exchanger exhaust fume collecting hood top, its architectural feature is to be provided with down deep bead between main heat exchanger exhaust fume collecting hood and the condensing heat exchanger, be provided with deep bead between condensing heat exchanger and the blower fan, following deep bead, condensing heat exchanger and last deep bead one common peripheral become the passage of smoke evacuation and heat exchange.
Be provided with deflector in the described passage.Deflector is arranged on the top of main heat exchanger exhaust fume collecting hood outlet.Deflector one end and following deep bead inwall or condensing heat exchanger bottom connection, the other end are hung on the top of main heat exchanger petticoat pipe outlet, and the outlet of main heat exchanger exhaust fume collecting hood is arranged on main heat exchanger exhaust fume collecting hood one side.Following deep bead bottom is provided with the condensed water delivery port, and a condensed water discharge pipe end up communicates with the condensed water delivery port.
Described blower fan is arranged on the side or the top of condensing heat exchanger.The water inlet pipe of condensing heat exchanger communicates with the main heat exchanger water inlet pipe through behind the condensing heat exchanger.
After flue gas in the utility model comes out from the main heat exchanger exhaust fume collecting hood, carry out heat exchange through condensing heat exchanger, behind blower fan, be discharged in the atmosphere again by exhaust opening, can effectively reduce the exhaust resistance of blower fan, can further improve the thermal efficiency of gas heater under the same conditions, save the electric energy loss of blower fan simultaneously.It has good energy-conserving effect, the thermal efficiency is high and make the processing characteristic of simple.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
Fig. 2 is the utility model user mode structural representation.
Among the figure: 1 is the outlet of main heat exchanger exhaust fume collecting hood, and 2 is condensing heat exchanger, and 3 is last deep bead, 4 is air inlet, and 5 is blower fan, and 6 is exhaust opening, 7 are following deep bead, 8 is the condensed water delivery port, and 9 is deflector, and 10 is the main heat exchanger exhaust fume collecting hood, 11 is main heat exchanger, 12 is water inlet pipe, and 13 is condensed water discharge pipe, and 14 is the main heat exchanger water inlet pipe.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1 and Fig. 2, the heat-exchanger rig of this condensed type combustion gas water heater comprises main heat exchanger petticoat pipe outlet 1, condensing heat exchanger 2, last deep bead 3, air inlet 4, blower fan 5, exhaust opening 6, following deep bead 7, condensed water delivery port 8 and deflector 9.
Main heat exchanger exhaust fume collecting hood 10 is positioned at main heat exchanger 11 tops, and condensing heat exchanger 2 is positioned at the top of main heat exchanger exhaust fume collecting hood 10, and blower fan 5 is positioned at the side of condensing heat exchanger 2.Be arranged on the following deep bead 7 between heat exchanger exhaust fume collecting hood 10 and the condensing heat exchanger 2 and be arranged on condensing heat exchanger 2 and blower fan 5 between last deep bead 3 and the heat exchanger fin of condensing heat exchanger 2 surround the passage of the smoke evacuation and the heat exchange of a sealing jointly, be provided with deflector 9 in the passage.Deflector 9 one ends and following deep bead 7 inwalls or condensing heat exchanger 2 bottom connections, the other end are hung on the top of main heat exchanger petticoat pipe outlet 1, and main heat exchanger exhaust fume collecting hood outlet 1 is arranged on main heat exchanger exhaust fume collecting hood 10 1 sides.Following deep bead 7 bottoms are provided with condensed water delivery port 8, and condensed water discharge pipe 13 end up communicates with condensed water delivery port 8.The water inlet pipe 13 of condensing heat exchanger 2 communicates with main heat exchanger water inlet pipe 14 through behind the condensing heat exchanger 2.
