Description
Technical field
The invention belongs to a kind of flow spoiler being arranged on tangential admission tower internal solution spiral-flow impact, be specifically related to
A kind of internal coiling ascending manner flow spoiler of tangential admission tower.
Background technology
Saturated wet flue gas temperature after the industry such as thermal power plant and petrochemical industry, wet desulfuration tower desulfurization
High, high humidity, from chimney discharge process, easily condensation forms drop, and part takes guttiferous wet flue gas row
Being diffused into after going out in air, some have little time diffusion, the big drop of evaporation will drop to chimney surrounding ground,
This phenomenon is referred to as " chimney rain ", and the environment of surrounding can be produced and pollute by " chimney rain ", and one of which subtracts
The way that little " chimney rain " pollutes is the mode that discharge flue gas tower uses tangential admission, makes flue gas enter
Form eddy flow after tower, the centrifugal force of gas can be utilized under the effect of eddy flow to take off part water droplet, but,
The eddy flow taking off water droplet can produce periodically impact, when the impact frequency of vortex during discharging to tower wall
When rate is equal to the natural frequency of tower, tower will be caused to resonate, the destructiveness to tower that resonates is big, has a strong impact on tower
Normal work, if it is possible to after flue gas takes off part water droplet by eddy flow effect, then change the inside of tower
Air flow method, then can be greatly reduced the vortex frequency that flow of flue gas produces, so can be effectively prevented from altogether
The generation shaken.
Summary of the invention
Present invention aims to the problems referred to above that tangential admission tower exists, it is provided that a kind of internal coiling rises
Formula flow spoiler, for improving the air flow method within tangential admission tower, the impact reducing the eddy flow within tower is made
With, thus reduce the vibration of tower.
It is an object of the invention to realize by the following technical solutions: on the internal coiling of this tangential admission tower
Lift-type flow spoiler, is characterized in: flow spoiler be arranged on higher than the tangential admission mouth 1 of tangential admission tower～3 meters with
On tower wall inside；Described flow spoiler is ascending manner helical arrangement and structure by some lamellar spoilers
Becoming, one end of every piece of spoiler is connected to inside tower wall.
Concrete, described spoiler size dimension is identical, or size dimension is different.
Concrete, described spoiler is the arrangement of ascending manner left-hand screw shape, or arranges in ascending manner right-hand screw shape,
And select the spiral angle of 30 °～60 ° and 0.1～0.5 meter respectively at tangential admission tower circumferential and axial
Spiral height.
Concrete, described spoiler or be distributed inside conical tower wall, or along straight tube shape tower wall
It is distributed inside face.
Concrete, when spoiler is along distribution inside conical tower wall, curved surface that spoiler free end surrounds or
Person is parallel with taper wall, forms the interior sky of reducing；Or axially in parallel with tower, form isometrical interior sky.
Concrete, one end of described spoiler with inside tower wall or employing is welded or screw thread links or grafting
Mode connect.
The present invention is by arranging spiral formula inside the tower wall of tangential admission mouth above certain altitude position
Flow spoiler, allows the flow in outflow mild after flow spoiler, is no longer distributed in eddy flow, the most effectively
Make use of eddy flow effect produced by tangential admission mouth, solve again eddy flow and tower produced periodic shock
Problem, reduces tower vibrations, improves the working environment of tower.

Detailed description of the invention
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1:
Seeing Fig. 1, Fig. 2, tangential admission tower includes tangential admission mouth 1, gas outlet 2, tower wall 3, this
The flow spoiler 41 of invention is arranged on higher than in the tower wall of 1～3m at the tangential admission mouth 1 of tangential admission tower
Side；In conjunction with Fig. 2, flow spoiler 41 by the lamellar spoiler 42 shown in some Fig. 2 in ascending manner helical form
Arrangement and constitute, one end of every piece of spoiler 42 or linked by welding or screw thread or the mode such as grafting even
