Shown in.
Shown in Fig. 8, Fig. 9, a described heat exchanger and secondary heat exchanger are separate structure, described
Water pipe by be positioned at a heat exchanger upper hose 2-1 and be positioned at secondary heat exchanger downcomer 2-2 connect and
Become；Be provided with upper sealing panel 13 in the bottom of a heat exchanger, the lower end of described upper water 2-1 is with upper sealing panel 13 even
Connecing, described thermal insulation board 5 is arranged on the upper of upper sealing panel 13；It is provided with lower seal plate 14 at the top of secondary heat exchanger,
The upper end of described downcomer 2-2 is connected with lower seal plate 14.
As shown in Figure 8, the top of a heat exchanger is annular collector pipe 3, is welded with some above
The upper hose 2-1 of (being 8 on schematic diagram), can place spring as required or have one in upper hose 2-1
The stainless steel substrates of shaped, makes the current in upper hose 2-1 form turbulent flow, strengthens heat transfer effect.Annular is catchmented
The material of pipe 3 and upper hose 2-1 is probably copper or rustless steel.
Heat exchange fin 15 is socketed in each upper hose 2-1, and is soldered.Annular collector pipe 3, upper hose
2-1 and heat exchange fin 15 are welded as a whole, and form heat exchange fin weldment.Heat exchanger bottom
High temperature resistant heat insulation plate 5, in order to will once, secondary heat exchanger be divided into two subregions of high/low temperature.If but two
Other thermal insulation board is had between individual heat exchanger, can also be without thermal insulation board on a heat exchanger.
The bottom of thermal insulation board 5 is rustless steel upper sealing panel 13, further will once, secondary heat exchanger segmentation
Become two cavitys, increase the intensity of whole heat exchanger simultaneously.
After one time heat exchanger assembly assembles, the straight tube exposing upper sealing panel 13 part will be increased by tube expansion
Diameter, in order to the downcomer 2-2 on secondary heat exchanger is to slotting connection.It is of course also possible to by secondary heat exchanger
On downcomer 2-2 tube expansion once major diameter, a Straight Pipes of Heat Exchanger not tube expansion, equally realize slotting connection.
As it is shown in figure 9, the bottom of secondary heat exchanger is annular distributive pipe 2, it is welded with some above
The downcomer 2-2 of (being 8 on schematic diagram), can place spring as required or have one in downcomer 2-2

The material of pipe 2 and downcomer 2-2 is rustless steel.
Secondary heat exchanger, near the bottommost of annular distributive pipe 2, is a condensation water collection dish 16.Collect
The condensed water of generation is condensed after high-temperature flue gas is cooled.
Heat exchange fin 15 is socketed in the downcomer 2-2 of each branch road, and is soldered.Heat exchange fin 15 top
Rustless steel lower seal plate 14, further will once, secondary heat exchanger be divided into two cavitys, increase simultaneously
The intensity of whole heat exchanger.
Annular distributive pipe 2, downcomer 2-2, condensation water collection dish 16, heat exchange fin 15 and lower seal plate
14 are welded as a whole, and form whole secondary heat exchanger assembly.
In heat exchanger, after water enters annular distributive pipe 2, it is divided into a number of branch road (schematic diagram
Shang Shi 8 branch), enter in annular collector pipe 3 after being heated, from the water out adapter of annular collector pipe 3 after collecting
Flow out.
As shown in Figure 10, the heat exchange of a kind of combustion gas full pre-mix condensing wall-hung boiler that the present embodiment provides
Device, its top is combustion chamber, and combustion gas produces high-temperature flue gas after combustion chamber burns, by this heat exchanger
Heat exchange fin realize the heat exchange between high-temperature flue gas and water at low temperature, water at low temperature is heated to uniform temperature
High-temperature water, the most automatically collects the condensed water produced after high-temperature flue-gas reduces, prevents corrosive cold
Solidifying water discharges, is leaked to outside boiler, causes environmental pollution.
During work, the high-temperature flue gas (pressing arrow to flow to) that burning produces, expands to the direction of surrounding 360 °
Dissipate, the gap between a heat exchanger heat exchange fin flow through, then from heat exchanger heat exchange fin and
Gap between shell is walked downwards, then between the direction of surrounding 360 ° flows through between secondary heat exchanger heat exchange fin
Gap, is pooled to the middle and lower part of heat exchanger, after condensation water collection dish 16, then by smoke exhaust pipe joint 12
Exhaust opening is discharged into outside heat exchanger.And water at low temperature enters heat exchanger from the water supply connector 6 of bottom, through heat exchange
The annular distributive pipe 2 of device bottom shunts, and each road water flows separately through and is welded on secondary heat exchanger heat exchange fin and once
Water pipe in heat exchanger heat exchange fin, is aggregated into the annular collector pipe 3 on top, finally connects from water outlet after being heated
7 flow out.
By above description, high-temperature flue gas, after flowing through first and second heat exchange fin, passes through heat exchange wing
Sheet heating water at low temperature, flue-gas temperature reduces, is condensed and discharges condensed water, it is achieved heating water at low temperature, offer
The purpose of high-temperature water.And the condensed water that flue gas produces, the water catch tray that is condensed collects collection, unified from condensation
Water interface is discharged into boiler exterior, and cooled flue gas becomes low-temperature flue gas, is discharged into by exhaust opening
Boiler exterior, the discharge of good effect of heat exchange, condensation water collection is convenient.
Essence of the present utility model has been described in detail by above detailed description of the invention, but can not be with
Protection domain of the present utility model is limited by this.It should be evident that opening in this utility model essence
Under showing, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that this
A little improvement and modification all fall within claims of the present utility model.
