Description
Technical field
The utility model is related to technical fields of discharging fume, and in particular to a kind of power plant's smoke evacuation system.
Background technology
The flue gas in power plant is after dedusting, desulfurization process, through cigarette after generally being reheated to flue gas using flue gas heat-exchange unit
Chimney discharges.Currently, being had the drawback that through smoke stack emission flue gas：The rising height of flue gas is limited, and the rise time is short, spreads height
It is low, it is unfavorable for environmental protection, be easy to cause prodigious environmental pollution.
Therefore, the smoke evacuation system in existing power plant need to be improved, to reduce environmental pollution.
Utility model content
In view of this, the purpose of this utility model is improved to existing smoke evacuation system, to reduce environmental pollution.
The utility model is solved the above problems by following technological means：A kind of power plant's smoke evacuation system, including chimney, it is described
Chimney top is provided with smoke outlet, and chimney bottom is provided with smoke inlet, and chimney jambs are provided with steam inlet, further includes steam production
Generating apparatus, the steam inlet are connected to steam generation device.
Further, it is provided with outside the chimney and send vapour cover, described that vapour cover is sent to be centered around outside chimney, the steam generation dress
It sets and is connected to vapour cover is sent, chimney jambs are circumferentially evenly arranged with multiple steam inlets, and multiple steam inlets are connected to vapour cover is sent,
Guiding device is provided at steam inlet, the guiding device includes two pieces of deflectors, both ends for being articulated with steam inlet both sides
Be hingedly connected to the connecting rod on the inside of two pieces of deflectors, for push deflector rotate electric cylinder and with the control circuit of electric cylinder
The controller of connection, described electric cylinder one end is hinged with deflector, and the other end is hinged with inner wall of stack.
Further, it is provided with check valve in the steam inlet.
Further, be provided with web plate in the chimney, the web plate by chimney be separated into smoke extraction chamber in upside and
Cushion chamber in downside, steam inlet are connected to cushion chamber.
The beneficial effects of the utility model：Power plant's smoke evacuation system of the application, including chimney, the chimney top are provided with
Smoke outlet, chimney bottom are provided with smoke inlet, and chimney jambs are provided with steam inlet, further include steam generation device, the steaming
Vapour entrance is connected to steam generation device.The smoke evacuation system of the structure, by the steaming for being passed through desired flow, flow velocity in chimney
Vapour, flue gas can be raised to atmospheric inversion layer under the action of steam heat buoyancy, and the lifting for substantially increasing flue gas emission is high
Degree, the time of rising is also longer, spreads height higher, meanwhile, flue gas can be disperseed to water down by steam, and the pollution of flue gas emission is more
Low, therefore, the smoke evacuation system of the application advantageously reduces environmental pollution.
Description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1-- chimneys, 3-- steam generation devices, 4-- send vapour cover.
Specific implementation mode
The utility model is described in detail below with reference to attached drawing.
Referring to Fig.1, power plant's smoke evacuation system shown in, including chimney 1, vapour cover 4 and steam generation device 3 are sent, state chimney top
Portion is provided with smoke outlet, and chimney bottom is provided with smoke inlet, described that vapour cover is sent to be centered around outside chimney, and the steam generation device is
Steam boiler or steam generator, steam generation device are connected to vapour cover is sent by steam conveying pipe, are arranged on jet chimney
Have a valve, chimney jambs are circumferentially evenly arranged with multiple steam inlets 2 close to the position of bottom, multiple steam inlets with send vapour
Cover is connected to, and is provided with guiding device at steam inlet, the guiding device includes two pieces of water conservancy diversion for being articulated with steam inlet both sides
Plate 5, both ends are hingedly connected to the connecting rod 6 on the inside of two pieces of deflectors, electric cylinder 7 and and electric cylinder for pushing deflector to rotate
Control circuit connection controller 8, described electric cylinder one end and deflector are hinged, and the other end is hinged with inner wall of stack.Using
The smoke evacuation system of the structure, on the one hand, steam is conveyed to sending by steam generation device in vapour cover, steam is flowed into through steam inlet
In chimney, flue gas can be raised to atmospheric inversion layer under the action of steam heat buoyancy, substantially increase the lifting of flue gas emission
Highly, the time of rising is also longer, spreads height higher, meanwhile, flue gas can be disperseed to water down by steam, and the pollution of flue gas emission is more
It is low, advantageously reduce environmental pollution；On the other hand, the flexible of electric cylinder is controlled by controller, deflector is made to turn around hinge joint
It is dynamic, to change the inflow direction of steam, the airflow direction of each steam inlet is adjusted to along circumferential clockwise of chimney or
Counterclockwise, air-flow can be made to form Swirling Flow, not only contribute to being sufficiently mixed for steam stream and flue gas, and row can be improved
Plume speed improves the height of smoke exhaust efficiency and lifting smoke evacuation, further advantageously reduces environmental pollution.In addition, to avoid flue gas
Adverse current enters to send in vapour cover, check valve 9 is provided in steam inlet, check valve, which limits air-flow, to have vapour hood to flow to chimney
It is interior.
It is further improved as to above-mentioned technical proposal, is provided with web plate 10 in the chimney, the web plate is by chimney
It is separated into the smoke extraction chamber 11 in upside and the cushion chamber 12 in downside, steam inlet is connected to cushion chamber.Cushion chamber energy
Extend the time that steam is mixed with flue gas, so that steam passes through web plate after being sufficiently mixed in cushion chamber with flue gas, then leads to
Smoke extraction chamber discharge is crossed, is conducive to make full use of the heat buoyancy of steam to act on.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
