The working principle of the utility model are as follows: the desulfurization neat stress after spray process contains a large amount of droplet, when this portion
After dividing flue gas to enter dust removing tube 1 from bottom, spiral board 3 makes desulfurization neat stress high speed rotation in dust removing tube 1, forms gas-liquid two-phase
Violent rotation and disturbance acted in spiral board 3 so that the fine drop in neat stress, which collides with each other, is agglomerated into big drop
Under, make the outside centrifugal movement of desulfurization neat stress, the big drop for polymerizeing formation rushes the inner wall of dust removing tube 1, by 1 inner wall surface of dust removing tube
Liquid film capture, achieve the purpose that remove finely ground particles, captured drop flows downward along inner wall, and later, flue gas comes
To at first defogging mechanism 5, flue gas flow to the top of mounting plate 51 and impacts umbrella baffle plate 53 by venthole 52
Bottom, separated since drop is different from gas inertia, the drop after collecting along umbrella baffle plate 53 bottom surface around
Flowing, and fall in flow-guiding channel 511, it eventually passes through leakage hole 512 and is discharged to lower section, after first defogging mechanism 5,
The flow velocity of flue gas has certain loss, at this time plays the role of speed-raising by speeder 6, then goes through second demisting
Mechanism 5 carries out demisting processing, thereafter lets out.
When flue gas flows through spiral board, under the action of separate sheet 34, occurs to turn to, accelerate, due to drop and gas
Body inertia is different and separates, and can improve drop separation efficiency, avoids droplets from reentrainment, flow-disturbing hole 341 enable to drop it
Between collision it is more violent, be conducive to demisting.
The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustively or to incite somebody to action
The utility model is limited to disclosed form.Many modifications and variations are aobvious and easy for the ordinary skill in the art
See.Embodiment was chosen and described in order to better illustrate the principle and practical application of the utility model, and makes this field
Those of ordinary skill it will be appreciated that the utility model to designing various embodiments suitable for specific applications with various modifications.
