Description
Technical field
The present invention relates to fuel gas buring, field of heat exchange, is a kind of novel condensed type combustion gas water heater.
Background technology
Gas heater is the equipment of a kind of fuel gas buring heating domestic water, in the productive life of extensive use and people.At present, most of gas heater adopts the mode of a heat exchange, and waste heat does not utilize, smog discharge temperature at about 150 degree, serious waste of resources.Some factories Domestic waste heat first heats the cold water entering water heater, and due to the limitation of the heat exchanger of employing, heat transfer effect is undesirable.
Summary of the invention
This programme be in order to solve gas heater energy utilization rate low and invention a kind of condensed type combustion gas water heater.
Described device is by assisting balancing boom device 1,2, exhaust outlet 9 on burner assembly 3, main heat exchanger 4, coupling sleeve 5, board-like secondary heat exchanger 6, poly-petticoat pipe 7, blower fan 8, shell 12, sealed parting strip 17, drainpipe and shell and air inlet 10 form, wherein main heat exchanger 4, coupling sleeve 5, board-like secondary heat exchanger 6, poly-petticoat pipe 7, blower fan 8 and exhaust outlet 9 sealed attachment UNICOM successively.
Balancing boom device, burner assembly, main heat exchanger are identical with conventional water heaters, realize the function to described device automatic feeding, igniting, burning, temperature control, protection.Board-like secondary heat exchanger is above master heat exchanger of gas water heater, and the heating of secondary heat exchanger fume afterheat enters fresh air combustion-supporting in stove.
Secondary heat exchanger forms by organizing plate more, gas approach, outlet, and fresh air inlet, outlet are all at the sidewall of plate, gas approach 14 is in lower surface, exhanst gas outlet 16 is in upper surface, and fresh air inlet 15 gathers petticoat pipe side in upper surface, and Fresh air vent 13 is below side end face.In heat exchanger, exhaust gases passes is called hot chamber, fresh air passage is called cold chamber.
The two ends sealed attachment main heat exchanger of coupling sleeve and secondary heat exchanger, the hot chamber of gas approach 14 through main heat exchange and secondary heat exchanger in coupling sleeve of secondary heat exchanger, exhanst gas outlet 16 is the hot chamber of through secondary heat exchanger and blower fan in poly-petticoat pipe, and the parts that main heat exchanger to air outlet of casing connects successively form the flue gas passage of heat of sealing jointly.
Described shell adopts hermetically-sealed construction, exhaust outlet 9 is established at the upper wall of shell, external air inlet mouth 10 is established above sidewall, and in the top of secondary heat exchanger Fresh air vent 13, the following peripheral part of fresh air inlet 15 establishes sealed parting strip 17, composition external air inlet mouth 10, sealed parting strip upper space, the cold chamber of secondary heat exchanger, the fresh air passage of sealed parting strip bottom main heat exchanger peripheral space, under the effect of blower fan, flue gas is by outside passage of heat discharge chamber, combustion chamber forms negative pressure, it is combustion-supporting to combustion chamber that extraneous air enters fresh air passage by air inlet 10, the two completes heat exchange by secondary heat exchanger, realize improving combustion air temperature, reduce the object of energy resource consumption.
Further, two side steppeds of coupling sleeve, bench floor perforate, Kong Shangshe condensed water connecting tube 19, drainpipe 24 is established in connecting tube bottom, and condensed water discharges out of the furnace along drainpipe.
Further, in order to prevent condensed water to the corrosion of coupling sleeve, aluminum condense water disk 11 being established by coupling sleeve sidewall step, tries to get to the heart of a matter and establish condensation-water drain, the condensed water that water pond is collected flows into condensate pipe along outlet and discharges.
Further, the bottom surface of secondary heat exchanger is skewed, middle high, and outside is low to facilitate condensed water to flow into condense water disk.
Further, dividing plate 23 is set in bottom, combustion chamber, forms independent control room, chamber outer wall perforate, ensures auxiliary element and use safety.
Further, assembling between main heat exchanger and secondary heat exchanger, secondary heat exchanger exhanst gas outlet 16 and exhaust outlet 9 UNICOM.
Further, exhaust outlet 9 is located at side wall of outer shell, to reduce the bend of smoke exhaust pipe.

After the burning of detailed description of the invention condensed type combustion gas water heater, first main heat exchanger is heated, due to coupling sleeve sealed attachment, flue gas enters the hot chamber of secondary heat exchanger from main heat exchanger again by heating domestic water, heating chamber wall (plate), flue-gas temperature declines, the moisture generation condensation in flue gas, condensed water drops down onto gas approach along plate and drops to condense water disk outflow, and the flue gas of rising is outside poly-petticoat pipe, blower fan discharge chamber.Due to the effect of blower fan, combustion chamber forms negative pressure, and fresh air enters the sealed parting strip upper space in stove from external air inlet mouth, enter the cold chamber of secondary heat exchanger from fresh air inlet 15, absorbing cavity wall heat, temperature improves, flow out from Fresh air vent 13, enter combustion chamber combustion-supporting.
Secondary heat exchanger adopts board-like aluminum design, and heat transfer effect is outstanding, flue-gas temperature can be made greatly to reduce, effectively reduce energy resource consumption.
