Description
Technical field
Flue gas desulfurization and dedusting field is the utility model is related to, more particularly to a kind of flue gas eddy flow for direct exhaust chimney fills
Put.
Background technology
Due to the sternness of Environmental Protection Situation, power plant, carbon element factory etc. build wet static dedusting system one after another.In view of traditional water
There is the problem of inconvenience maintenance in mud chimney, most of producer's selection uses free-standing steel chimney, and free-standing steel chimney has maintenance
The features such as convenience, low cost, short time limit.
After wet electrical dust precipitator puts into operation, with the increase of water content in flue gas, a large amount of steam are carried along into steel by neat stress
Small water droplet is formed after chimney to the cold, small water droplet is discharged outside chimney under " promotion " of flue gas, into air after due to without
Thrust, small water droplet are just dropped near chimney, cause the phenomenon of " rainy " near chimney, the equipment and factory to surrounding
Production can cause worse influence, to water resource and a kind of waste.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of flue gas eddy flow for direct exhaust chimney and filled
Put, it has simple in construction, easy for installation, low cost, can intercept inside chimney the small water droplet in flue gas, avoid chimney
The effect that " rainy " phenomenon occurs.
The utility model uses following technical proposals：
A kind of flue gas swirl-flow devices for direct exhaust chimney, including multiple fan blades and support tube inside chimney are arranged at,
Described support tube is located at the bottom of fan blade；
One end of multiple fan blades is fixed together, and the other end radially distributes and is fixed on inner wall of stack；Described
Support tube is connected with fan blade and its center and fan blade center superposition.
Further, described support tube includes multiple cross-brace pipes and a vertical supporting pipe, described horizontal branch
One end of stay tube and one end of fan blade are linked together by vertical supporting pipe, and vertical supporting pipe rises to cross-brace pipe and fan blade
To supporting role；The other end of described cross-brace pipe is fixed on inner wall of stack.
Further, described cross-brace pipe is uniformly distributed in inside chimney.
Further, one end of described fan blade and one end of support tube weld together, and the other end is welded in chimney
On wall；The other end of described cross-brace pipe is welded on inner wall of stack.
Preferably, described cross-brace Guan Weisi, four cross-brace pipes are in cross distribution.
Preferably, described fan blade is three, and the angle between adjacent fan blade is 120 °.
Further, described fan blade and support tube select 2205 stainless steels.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model by the inside of chimney set fan blade, the small water droplet in flue gas is intercepted inside chimney,
So as to avoid chimney " rainy " phenomenon, surrounding devices are protected, keep the normal production in field, save water source；
(2) the utility model only includes fan blade and support tube, and simple in construction, easy for installation, low cost, support tube is to fan blade
Play a part of fixed support, because the end of support tube and fan blade is all welded on inner wall of stack, therefore, fan blade was using
Loose phenomenon is less prone in journey, is increased the service life.
Brief description of the drawings
The Figure of description for forming the part of the application is used for providing further understanding of the present application, and the application's shows
Meaning property embodiment and its illustrate be used for explain the application, do not form the improper restriction to the application.
Fig. 1 is structural representation of the present utility model；
Wherein, 1- fan blades, 2- chimneys, 3- support tubes.
Embodiment
It is noted that described further below is all exemplary, it is intended to provides further instruction to the application.It is unless another
Indicate, all technologies used herein and scientific terminology are with usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It should be noted that term used herein above is merely to describe embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
It is also intended to include plural form, additionally, it should be understood that, when in this manual using term "comprising" and/or " bag
Include " when, it indicates existing characteristics, step, operation, device, component and/or combinations thereof.
As background technology is introduced, the deficiency for thering is " rainy " phenomenon to occur when near chimney in the prior art be present,
In order to solve technical problem as above, present applicant proposes a kind of flue gas swirl-flow devices for direct exhaust chimney.
In a kind of typical embodiment of the application, as shown in Figure 1, there is provided a kind of flue gas for direct exhaust chimney revolves
Device is flowed, including is arranged at multiple fan blades 1 and support tube 3 inside free-standing steel chimney, described support tube 3 is located at fan blade 1
Bottom, fan blade 1 is played a supporting role.
One end of multiple fan blades 1 is fixed together, and the other end radially distributes and is fixed on the inwall of chimney 2；Institute
The support tube 3 stated is connected with fan blade 1 and its center and the center superposition of fan blade 1, the center of fan blade 1 and the center of chimney 2
Unanimously.
Described support tube 3 includes multiple cross-brace pipes and a vertical supporting pipe, and the one of described cross-brace pipe
End and one end of fan blade 1 link together and are fixed on vertical supporting pipe；The other end of described cross-brace pipe is fixed on
On the inwall of chimney 2.
Described cross-brace pipe can be four, and four cross-brace pipes are in cross distribution；The number of cross-brace pipe
Mesh is not limited to four, as long as meeting that cross-brace pipe is uniformly distributed in the inside of chimney 2；Specific number is according to using process
