Abstract
The utility model discloses a kind of expanding type flue gas mixing case apparatus, including flue gas mixing tank ontology, the flue gas mixing tank ontology left side wall is fixedly welded with air door, the flue gas mixing tank body bottom portion is equipped with flue gas butterfly valve, the side wall of the air door is equipped with rectangle door closure, and rectangle door closure is fixedly mounted on air door by eight fastening bolts, and the cross sectional shape of air door is circle, the valve plate shape of the flue gas butterfly valve is also round, air blower connector is equipped in the middle part of the right side wall of the flue gas mixing tank ontology, the sectional area of the mixing tank ontology is bigger than the inlet air open area of smoke inlet and air door.This expanding type flue gas mixing case apparatus, the sectional area of flue gas mixing cabinet is bigger than the air intake vent of air door and smoke inlet area, volume enlargement, after wind and flue gas enter mixing tank, air velocity reduces, mutual interference is preferably minimized, and avoids wind and the case where flue gas fights for channel, and when burner operation is more reliable and more stable.
Description
Technical field
The utility model relates to flue gas mixing tank technical field, specially a kind of expanding type flue gas mixing case apparatus.
Background technique
Conventional flue gas mixing tank and air-admitting surface are essentially identical, and when circulating flue gas is added, flue gas is easy to happen with air
Interference, the amount both caused this it is high that is low, while the mixing of flue gas and air is also uneven, steadily not to the burning of burner
Benefit.
Utility model content
The purpose of this utility model is to provide a kind of expanding type flue gas mixing case apparatus, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions：A kind of expanding type flue gas mixing case apparatus, packet
Flue gas mixing tank ontology is included, the flue gas mixing tank ontology left side wall is fixedly welded with air door, the flue gas mixing tank ontology bottom
Portion is equipped with flue gas butterfly valve, and the side wall of the air door is equipped with rectangle door closure, and rectangle door closure passes through the fixed peace of eight fastening bolts
On air door, the height of the flue gas mixing tank ontology is greater than the height of air door, and the cross sectional shape of air door is circle, described
The valve plate shape of flue gas butterfly valve is also circle, is equipped with air blower connector, institute in the middle part of the right side wall of the flue gas mixing tank ontology
The sectional area for stating mixing tank ontology is bigger than the inlet air open area of smoke inlet and air door.
Preferably, the rectangular door is covered equipped with screen pack.
Preferably, the diameter of the air door is less than the length of flue gas mixing tank ontology.
Compared with prior art, the utility model has the beneficial effects that：This expanding type flue gas mixing case apparatus,
The sectional area of flue gas mixing cabinet is bigger than the air intake vent of air door and smoke inlet area, volume enlargement, wind and flue gas
Into after mixing tank, air velocity is reduced, and mutual interference is preferably minimized, avoids wind and flue gas fights for the feelings in channel
Condition, when burner operation, are more reliable and more stable.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model side structure schematic view；
Fig. 3 is the utility model present invention looks up structural representation.
In figure：1 flue gas mixing tank ontology, 2 air doors, 3 flue gas butterfly valves, 4 air blower connectors, 5 rectangle door closures.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution：A kind of expanding type flue gas mixing case apparatus, including
Flue gas mixing tank ontology 1,1 left side wall of flue gas mixing tank ontology are fixedly welded with air door 2, the flue gas mixing tank ontology 1
Bottom is equipped with flue gas butterfly valve 3, and the side wall of the air door 2 is equipped with rectangle door closure 5, and rectangle door closure 5 passes through eight fastening bolts
It is fixedly mounted on air door 2, the height of the flue gas mixing tank ontology 1 is greater than the height of air door 2, and the cross sectional shape of air door 2
For circle, the valve plate shape of the flue gas butterfly valve 3 is also circle, is equipped with drum in the middle part of the right side wall of the flue gas mixing tank ontology 1
The sectional area of blower connector 4, the mixing tank ontology 1 is bigger than the inlet air open area of smoke inlet and air door 2.
Specifically, the rectangle door closure 5 is equipped with screen pack.
Specifically, the diameter of the air door 2 is less than the length of flue gas mixing tank ontology 1.
When specifically used, the sectional area of flue gas mixing cabinet 1 is bigger than the air intake vent of air door 2 and smoke inlet area, volume
After expansion, wind and flue gas enter mixing tank, air velocity is reduced, and mutual interference is preferably minimized, and avoids wind and flue gas
The case where fighting for channel, when burner operation, are more reliable and more stable.
In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu
It is fixed " etc. terms shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the present invention.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
