One flue gas interface 200 and the second flue gas interface 300, the flue gas cooling chamber 100 are additionally provided with for example cold for liquid cooling medium
Water importing, derived first cooling medium interface 110 and the second cooling medium interface 120, the bottom of the flue gas cooling chamber 100
Gas reversal chamber 400 is provided with, some smoke pipes 130 connect through the gas reversal chamber 400 and second flue gas interface 300
It is logical.For the ease of collecting and clearing up flying dust, the gas reversal chamber 400 has a funnel-shaped bottom portion 410, and the infundibulate bottom
Portion 410 connects flue-dust retainer 500 so that the flying dust to be dropped in flue gas steering procedure falls into flue-dust retainer 500 via funnel-shaped bottom portion 410
In, it is easy to concentrate and clears up.
If cooling medium is changed into air, the application can turn into air preheater, identical with the purpose of economizer, and
Reduce exhaust gas temperature.
In this embodiment, dropped for the ease of flue gas cooling and flying dust, some smoke pipes 130 are longitudinal
Set and parallel to each other, one end of some smoke pipes 130 connects with first flue gas interface 200, the other end and institute
The second flue gas interface 300 is stated to connect.Wherein, the first flue gas interface 200 and second flue gas interface 300 are separately positioned on described
Above and below flue gas cooling chamber 100, the first cooling medium interface 110 and the second cooling medium interface 120 divide
The top and bottom of the flue gas cooling chamber 100 are not arranged on.In order to fully radiate, the outer surface of smoke pipe 130 can be set
Screw thread.
In this embodiment, the direction of first flue gas interface 200 and second flue gas interface 300 can be with
Adjust in the horizontal direction.Herein on basis, it is actually needed according to heat exchange amount and exhaust gas volumn etc., multiple same economizers can be with
Pass through first flue gas interface 200, the second flue gas interface 300, the first cooling medium interface 110 and the second cooling medium interface
120 are one another in series or in parallel form economizer group.As shown in Fig. 2 the schematic diagram for two economizer series connection.Now, wherein one
The first flue gas interface that individual first flue gas interface 200 still imports as flue gas uses, and another first flue gas interface 200 is then made
Flue gas is exported for the second flue gas interface；Similarly, one of them first cooling medium interface 110 is still used as the first cooling medium
For interface using to import cooling medium, another the first cooling medium interface 110 is then used as the second cooling medium interface to lead
Go out cooling medium.
As shown in figure 3, the schematic diagram for the application another kind embodiment.A kind of economizer, including internal setting
Have the flue gas cooling chamber 100 of some smoke pipes 130 and the first flue gas interface 200 for being connected respectively with some smoke pipes 130 and
