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
All other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, the utility model embodiment provides a kind of Wet chimney that can prevent and treat chimney rain, including expanding chimney sheet
Body 1, the expanding chimney body 1 is interior to be equipped with dropping liquid collecting tank 2, air flow guiding device 3 and drain water piping 4；The expanding chimney
The diameter of ontology 1 is incremented by by smoke inlet to outlet flue；The air flow guiding device 3 is co-axially mounted with the expanding chimney body 1, institute
The outer ring for stating air flow guiding device 3 is equipped with dropping liquid collecting tank 2, and one end of the drain water piping 4 and the dropping liquid collecting tank 2 connect
Logical, the other end extends to outside the expanding chimney body 1.When flue gas enters in expanding chimney body 1 from smoke inlet, directly and gas
It flows air deflector 3 to contact, forms first time gas-liquid separation, is i.e. gas phase media continues up, and liquid phase medium is produced with air flow guiding device 3
Raw centripetal force enters in dropping liquid collecting tank 2 corresponding with 3 circumference of air flow guiding device, and then by corresponding with dropping liquid collecting tank
Drain water piping 4 be discharged to outside expanding chimney body 1.
Further, the folder between the inner wall of the expanding chimney body 1 and the central axis of the expanding chimney body 1
Angle is 5 ~ 15 °.Preferably, the angle between the inner wall of the expanding chimney body and the central axis of the expanding chimney body
It is 10 °.Inner wall convenient for dropping liquid along expanding chimney body 1 enters in dropping liquid collecting tank 2.
Further, as shown in Figure 1, the gas outlet at 5 top of the smoke inlet end of the expanding chimney body 1 and tower body connects
It is logical, prevent flue gas from revealing, the longitudinal section at 5 top of tower body is isosceles trapezoid shape, and 5 top of the tower body and the expanding cigarette
The diameter of one end of the smoke inlet end connection of chimney ontology 1 is less than described 5 one end of top far from the expanding chimney body 1 of tower body
Diameter.Expanding chimney body 1 is formed along expanding chimney body 1 and 5 top connectivity part of tower body to both sides with tower body 5 in flaring shape
" venturi " pipe, expanding chimney body 1 reinforced by welding with tower body 5, increases the stabilization of structure with this
Property.
Venturi effect can be generated when flue gas rises, and enters expanding chimney body 1 from tower body, when flue gas is in Venturi tube
When the inside is flowed, at the most narrow place of pipeline, dynamic pressure reaches maximum value, static pressure reach the speed of minimum value flue gas because
Rise for the reduction of through flow cross section area, pipe reductions process will be undergone within the same time by entirely shoving, thus pressure
Also reducing in the same time, and then generate pressure difference, this pressure difference is for measurement or fluid is given to provide an external suction,
In the suction adsorption to the inner wall of expanding chimney body 1 for generating the liquid phase medium in flue gas gradually by Venturi effect, slide
It to dropping liquid collecting tank 2, is discharged finally by drain water piping 4, the moisture content in flue gas is reduced with this, is subtracted to greatest extent
The outer of few drop avoids that " chimney rain " phenomenon occurs when flue gas outlet.
Further, the dropping liquid collecting tank 2 and the air flow guiding device 3 be installed on the expanding chimney body 1 into
Mouth end.It can be determined according to chimney draft Media density and air velocity as setting how many of air flow guiding device 3.
Further, the air flow guiding device 3 includes rotatable several blades, the folder of each blade and air current of smoke removal
Angle is 40 ~ 50 °.When wet flue gas rising, 3 are contacted with air flow guiding device first, wet flue gas enters dropping liquid air deflector from smoke inlet
3, under the rotatable blade effect of dropping liquid air deflector 3, preliminary gas-liquid separation is formed, gas rises, by isolated liquid
Into in dropping liquid collecting tank 2, aqueduct 4 is flowed by weep hole and is drained into the trench of region.
Further, the outer ring of the dropping liquid collecting tank 2 is bonded welding with the inner wall of the expanding chimney body 1.Pass through
Seamless welding technology connect the inner wall of expanding chimney body 1 with 2 outer ring of dropping liquid collecting tank, when the liquid phase medium in wet flue gas is logical
It crosses Venturi effect to be attracted on the inner wall of expanding chimney body 1, during sliding to dropping liquid collecting tank 2, avoids liquid
It penetrates into the gap at solder joint because welding insufficient appearance, and then corrodes tower body 5.
Further, weep hole, the weep hole and the drain water piping are provided on the bottom plate of the dropping liquid collecting tank 2
4 connections.
Further, along the circumferential direction spaced set has several weep holes, each institute on the bottom plate of the dropping liquid collecting tank 2
Weep hole is stated to be connected to the corresponding drain water piping 4 respectively.As shown in Fig. 2, on the bottom plate of dropping liquid collecting tank 2 along the circumferential direction
Spaced set has 6 weep holes, avoids the occurrence of because long-time is discharged fume, accumulates the corrosive deposit in flue gas, cause weep hole
Blocking influences the normal work of entire drainage system, and each weep hole is connected to corresponding drain water piping 4 respectively, will be collected
To liquid phase medium be discharged into the trench of region by weep hole and drain water piping 4, avoid this with acid harmful sewage stream
It is put into the environment near plant area and causes secondary pollution.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
