Description
Technical field
The present invention relates to filed of flue gas purification, particularly relate to a kind of flue gas desulfurization rapidly tower.
Background technology
Dual alkali is to use sodium base desulfurizer to carry out desulfurization in tower, owing to sodium base desulfurizer alkalescence is strong, absorbs
After sulfur dioxide, product solubility is big, does not results in supersaturation crystallization, causes fouling and clogging problem.
On the other hand desulfurization product is discharged into the interior calcium hydroxide of regenerated reactor and carries out reducing/regenerating, the sodium base regenerated
Desulfurizing agent is returned desulfurizing tower again and is recycled.Double alkali method desulfurizing technology reduces investment and operating cost,
It is relatively specific for medium small boiler and carries out desulfurizing fly ash.
Tradition desulfurizing tower structural principle be generally divided into following several: one, liquid column type desulfurization: doctor solution from
The mouth of pipe sprays, and occurs to contact for 2 times with flue gas rising, make the Containing Sulfur in flue gas during falling
Compound reacts with doctor solution, reaches desulfurized effect；Two, spraying type desulfurization: jet pipe sprays mist in face of flue gas
Shape doctor solution, increases flue gas and the contact area of doctor solution, and in flue gas, Containing Sulfur and thing react with doctor solution
Reach desulfurized effect；Three, bubbling type desulfurization: using jet pipe to be passed through in doctor solution by flue gas, flue gas is formed
Bubble contacts Containing Sulfur and thing in flue gas and has reacted desulfurization with doctor solution with doctor solution.
Existing flue gas desulfurization device mainly has the disadvantage that: 1, spray mode desulfurization, flue gas and doctor solution
Contact dynamics limited, contact area is uneven, bad desulfurization effects.Not only desulfurization is not thorough, and
Doctor solution and desulfurizing tower contact area are very big, easily corrode desulfurizing tower；2, contact with doctor solution at flue gas
During, flue gas is that cylinder contacts with doctor solution, this way of contact, flue gas and the contact surface of doctor solution
Long-pending limited, cause bad desulfurization effects.
How to design a kind of flue gas desulfurization rapidly tower, after uniform to flue gas and doctor solution strong stirring, then and
Doctor solution carries out strength and liquidates, and improves the haptoreaction area of flue gas and doctor solution and contacts dynamics, raising
Desulfurized effect becomes a problem needing solution badly.
