Description
Technical field
The present invention relates to fuel gas buring, field of heat exchange, be 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, extensively in the productive life of application and people.At present, big portion
Point gas heater uses 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 the limitation of the heat exchanger owing to using, heat transfer effect is undesirable.
Summary of the invention
This programme is to solve that gas heater energy utilization rate is low and a kind of condensed type combustion gas water heater of inventing.
Described device is by assist control components and parts 1,2, burner assembly 3, main heat exchanger 4, coupling sleeve 5, board-like secondary heat exchanger 6, poly-
Exhaust outlet 9 and air inlet 10 on petticoat pipe 7, blower fan 8, shell 12, sealed parting strip 17, drain pipe and shell form, Qi Zhongzhu
Heat exchanger 4, coupling sleeve 5, board-like secondary heat exchanger 6, poly-petticoat pipe 7, blower fan 8 and exhaust outlet 9 sealingly connect UNICOM successively.
Control components and parts, burner assembly, main heat exchanger identical with conventional water heaters, it is achieved to described device automatic feeding, light a fire, burn,
Temperature control, the function of protection.Board-like secondary heat exchanger above master heat exchanger of gas water heater, secondary heat exchanger fume afterheat heat into
Fresh air combustion-supporting in entering stove.
Secondary heat exchanger is formed by organizing plate more, gas approach, outlet, and fresh air inlet, outlet are all at the sidewall of plate, gas approach
14 in lower surface, and exhanst gas outlet 16 is in upper surface, and fresh air inlet 15 is poly-petticoat pipe side, Fresh air vent 13 in upper surface
Below side end face.In heat exchanger, exhaust gases passes is referred to as hot chamber, fresh air passage is referred to as cold chamber.
The two ends of coupling sleeve sealingly connect main heat exchanger and secondary heat exchanger, and the gas approach 14 of secondary heat exchanger through master in coupling sleeve change
Heat and the hot chamber 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 main heat exchanger is to shell
The parts that air outlet couples successively collectively constitute the flue gas passage of heat of sealing.
Described shell uses and seals structure, and the upper wall at shell sets exhaust outlet 9, sets external air inlet mouth 10 above sidewall, and new at secondary heat exchanger
The following peripheral part of the top of fresh air outlet slit 13, fresh air inlet 15 sets sealed parting strip 17, composition external air inlet mouth 10, close
Packing bar upper space, the cold chamber of secondary heat exchanger, the fresh air passage of sealed parting strip bottom main heat exchanger peripheral space, at blower fan
Under effect, flue gas is by outside passage of heat discharge chamber, and combustor forms negative pressure, and extraneous air enters fresh air by air inlet 10 and leads to
Road is combustion-supporting to combustor, and the two completes heat exchange by secondary heat exchanger, it is achieved improve combustion air temperature, the mesh of minimizing energy resource consumption
's.
Further, two side steppeds of coupling sleeve, bench floor perforate, Kong Shangshe condensed water connecting tube 19, connecting tube bottom sets
Drain pipe 24, condensed water discharges out of the furnace along drain pipe.
Further, in order to prevent the condensed water corrosion to coupling sleeve, coupling sleeve sidewall step sets aluminum condensation water pond 11, tries to get to the heart of a matter and set condensation
Water out, the condensed water that water pond is collected flows into condensate pipe along outlet and discharges.
Further, the inclined shape in bottom surface of secondary heat exchanger, middle high, outside is low to facilitate condensed water to flow into condensed water dish.
Further, dividing plate 23 is set in combustor bottom, forms independent control room, chamber outer wall perforate, it is ensured that 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 specific embodiments condensed type combustion gas water heater, first heating main heat exchanger, owing to coupling sleeve sealingly connects, flue gas is from master
Heat exchanger enters back into the hot chamber of secondary heat exchanger, heating cavity wall (plate) by heating domestic water, and flue-gas temperature declines, in flue gas
Moisture condenses, and condensed water drops down onto gas approach along plate and drops to condense water pond outflow, and the flue gas of rising is discharged through poly-petticoat pipe, blower fan
Outdoor.Due to the effect of blower fan, combustor forms negative pressure, and fresh air enters the sealed parting strip upper space in stove from external air inlet mouth,
Entering the cold chamber of secondary heat exchanger from fresh air inlet 15, absorb cavity wall heat, temperature improves, and flows out from Fresh air vent 13,
Entrance combustor is combustion-supporting.
Secondary heat exchanger uses board-like aluminum design, and heat transfer effect is outstanding, flue-gas temperature can be made to be substantially reduced, effectively reduce energy resource consumption.
