Description
Technical field
The utility model relates to gas heater technical fields, more particularly to a kind of air balance regulating device and combustion gas
Water heater.
Background technique
Traditional, gas heater is typically all that an exhaust fume collecting hood is installed above its heat exchanger, and gas heater produces
Raw flue gas is collected by exhaust fume collecting hood, then the air-flow to be formed is driven to emit together by blower.Due to gas heater
Inner space than relatively limited, the structure of exhaust fume collecting hood cannot generally accomplish symmetrically, this allow for exhaust fume collecting hood ventilation when its
The ventilation situation of position is different, unevenly, uneven so as to cause the primary and secondary air of burner, is unfavorable for firing
The completely burned of burner.In addition, the combustion gas in the burner below breezy heat exchanger can be in completely burned
The combustion gas in burner below the heat exchanger of ventilation difference is then not easy completely burned, is easy to cause the bad control of flue gas even
It is exceeded.
Utility model content
Based on this, first technical problem that the utility model is solved is to provide for a kind of air balance regulating device,
Its uniformity that can efficiently control flow of flue gas makes so that the flow of flue gas that burning generates when gas heater is run is uniform
Burning is more complete when obtaining gas heater operation.
Second technical problem that the utility model is solved is to provide for a kind of gas heater, can efficiently control
The uniformity of flue gas stream, the flow of flue gas for guaranteeing that burning generates when operation is uniform, guarantees that burning is more complete when operation.
Above-mentioned first technical problem is solved by the following technical programs:
A kind of air balance regulating device, the inlet of the exhaust fume collecting hood for gas heater to be arranged in, including air-flow are flat
Weigh adjustable plate, and at least two groups venthole is offered on the air balance adjustable plate, and the setting of venthole described at least two groups is used
In corresponding with the structure of exhaust fume collecting hood, the smooth degree of flow of flue gas at venthole described in every group is used for and flue gas stream in exhaust fume collecting hood
Smooth degree is moved to be inversely proportional.
Air balance regulating device described in the utility model, it is generated the utility model has the advantages that the gas compared with the background art
Mobile equilibrium regulating device using when for the inlet of the exhaust fume collecting hood of gas heater to be arranged in, air balance adjustable plate can
It is adjusted according to mobility of the uneven texture of exhaust fume collecting hood to the flue gas for entering exhaust fume collecting hood, i.e., on air balance adjustable plate
Each group venthole can be upset to non-uniform flue gas is flowed, and flow of flue gas more has some setbacks place in exhaust fume collecting hood, corresponding
Flow of flue gas at the venthole at place is more smooth, the more smooth place of flow of flue gas in exhaust fume collecting hood, and the described of corresponding section is led to
Flow of flue gas at stomata more has some setbacks, so that non-uniform flue gas stream reaches the state to tend to balance again, allows cigarette
Mobility status of the gas in exhaust fume collecting hood position tends to uniformly, effectively controls the discharge uniformity that flue gas passes through smoke exhaust pipe, in turn
The flow of flue gas for guaranteeing that burning generates when gas heater operation is uniform, so that burning is more complete when gas heater is run.

It is smooth, it flows that smooth place is corresponding with flue gas 10 in exhaust fume collecting hood 200, enables to flue gas 10 in 200 position of exhaust fume collecting hood
Mobility status tends to uniformly, and arranges degree by using the density of providing holes to control 10 uniformity of flue gas, and flue gas 10 controls
More convenient, structure is simple, and the design of air balance adjustable plate 110 is convenient.
Further, it is also possible to the hole size of venthole 112 described in every group is respectively provided with different from the density in hole arrangement degree,
It can specifically be designed according to the actual situation, flexible design.
The shape of the venthole 112 can be circular hole or slot in one of the embodiments,.In this way, air balance
112 structure flexible design of each group venthole on adjustable plate 110, can according to the actual situation or the specific structure phase of exhaust fume collecting hood 200
It should design, by using the structure of circular hole or slot, design simpler.In addition, the shape of venthole 112 is also possible to other
Arbitrary shape, it is without being limited thereto.
Further, venthole 112 described in every group is that ventilation is mesh-structured.It so, it is possible preferably through 10 gas of flue gas
Stream guarantees that flue gas 10 passes through air balance adjustable plate 110 and enters in exhaust fume collecting hood 200.
Specifically, the air balance adjustable plate 110 is used to be mounted on the exhaust fume collecting hood 200 of gas heater or combustion gas is hot
On the heat exchanger 300 of hydrophone.At the entrance that air balance adjustable plate 110 only needs to guarantee to be located at exhaust fume collecting hood 200, ascend the throne
It is specific mountable on the exhaust fume collecting hood 200 of gas heater between the exhaust fume collecting hood 200 and heat exchanger 300 of gas heater
Or the heat exchanger 300 of gas heater, it is flexible for installation, conveniently.
Further, the air balance regulating device 100 further includes installation side plate 120, and the installation side plate 120 is arranged
In the plate edge of the air balance adjustable plate 110, the air balance adjustable plate 110 by the installation side plate 120 with
