Further, the external blower of the smoke inlet.

Further, from the upper part of the housing, bending is arranged the smoke-outlet flue to the lower part, and the smoke-outlet flue is in the shell Body lower part is provided with exhanst gas outlet.

The beneficial effects of the utility model are: a kind of condensation heat exchange device, including shell, it is equipped in the shell cold Condenser, flue gas flow equalizing plate；The shell includes Heat Room and the smoke-outlet flue in Heat Room top setting, the heat exchange Room lower part is equipped with smoke inlet；Flue gas flow equalizing plate interval is connected in the Heat Room, and the condenser includes water inlet, goes out The water pipe of the mouth of a river and bendable, the water pipe pass through the flue gas flow equalizing plate, and cold water flows in water pipe, Heat exchange is carried out with the high-temperature flue gas in Heat Room, flue gas uniform divided flows can be kept water abundant with flue gas heat by flue gas flow equalizing plate Heat exchange is carried out, smoke heat energy reuse efficiency is greatly improved.

Detailed description of the invention

It is described further below in conjunction with attached drawing and example.

Fig. 1 is that the internal structure main view signal of the utility model and flue gas move towards figure；

Fig. 2 is the internal structure left view schematic diagram of the utility model；

Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model Limitation.

Referring to figs. 1 to Fig. 3, a kind of condensation heat exchange device, including shell 1, condenser 2, cigarette are installed in the shell 1 Gas homogenizing plate 3；The shell 1 includes Heat Room 11 and the smoke-outlet flue 12 in 11 top of Heat Room setting, the heat exchange 11 lower part of room is equipped with smoke inlet 13；The interval of flue gas flow equalizing plate 3 is connected in the Heat Room 11, the flue gas flow equalizing plate 3 By the Heat Room 11 every being divided into several gas chambers, several ventholes 31 are provided on the flue gas flow equalizing plate 3；The condensation Device 2 is connected in the Heat Room 11, and the condenser 2 includes the water pipe of water inlet 21, water outlet 22 and bendable 23, the water pipe 23 passes through the flue gas flow equalizing plate 3.In actual work, external gas and hot water kiln gas accesses smoke inlet 13, high-temperature flue gas enters Heat Room 11 from smoke inlet 13, and high-temperature flue gas rises, divided by the venthole 31 on flue gas flow equalizing plate 3 Flow to each gas chamber；External cold water accesses water inlet 21, and cold water carries out hot friendship with high-temperature flue gas in each gas chamber along water pipe 23 Change, since flue gas flow equalizing plate 3 is to the shunting function of flue gas, high-temperature flue gas is uniformly dispersed, each gas chamber high temperature flue gas with Water pipe 23 carries out sufficient heat exchange, and the shunting function of flue gas flow equalizing plate 3 effectively prevent high-temperature flue gas occur only exchanging heat The problem of side of room 11 rises, and high-temperature flue gas and 2 insufficient contact of condenser is caused to reduce heat exchanger effectiveness；By heat exchange Afterwards, high-temperature flue-gas is gradually reduced, and water temperature rises in water pipe 23, and final cold water is discharged after being heated from water outlet 22, Water outlet 22 and external gas water-heating furnace are connected, and low-temperature flue gas is discharged by smoke-outlet flue 12；Realize the thermal energy to high-temperature flue gas Efficiently using, to the function of discharging after flue gas cool-down and preheated simultaneously to cold water again.

Preferably, the flue gas flow equalizing plate 3 is transversely mounted and at least installs one, when being conducive to rise high-temperature flue gas Shunting function.

Preferably, the upper end of the condenser 2 is arranged in the water inlet 21, and the water outlet 22 is arranged in the condensation The lower end of device 2, since high-temperature flue gas enters from the lower part of shell 1, flue-gas temperature is gradually reduced from lower to upper in Heat Room 11, will External cold water enters from the upper end of condenser 2, and water is flowed from the low-temperature region in Heat Room 11 to high-temperature area, is gradually added Heat is finally discharged in the water outlet 22 of the high-temperature area of Heat Room 11, effectively improves heat exchanger effectiveness.

Preferably, the external blower of the smoke inlet 13, high-temperature flue gas are blown into Heat Room 11 by blower, accelerate high temperature cigarette The flowing of gas.

Preferably, from 1 top of shell, bending is arranged the smoke-outlet flue 12 to the lower part, and the smoke-outlet flue 12 is in institute It states 1 lower part of shell and is provided with exhanst gas outlet 111；Flue gas is completed in Heat Room 11 with after the heat exchange of condenser 2, and there is also certain Temperature, turnover design smoke-outlet flue 12, increases flow path when flue gas discharge, and flue gas can be made to continue cooling and be then exhausted from, had Conducive to environment, bending designs the volume for also taking full advantage of shell 1, reduces space occupy-place.

Although the embodiments of the present invention have been shown and described above, it is to be understood that above-described embodiment is Illustratively, it should not be understood as limiting the present invention, those skilled in the art are in the scope of the utility model Inside it can make changes, modifications, alterations, and variations to the above described embodiments.
