Abstract
The utility model discloses a desulfurized slurry aeration-boosting deep oxidation device, belongs to wet desulfurization equipment, and particularly provides a desulfurized slurry aeration-boosting device for desulfurization equipment. The aeration-boosting deep oxidation device comprises an aeration oxidation tube fixed in a desulfurization tower through a support rack, wherein an oxidation air inlet is formed in the upper end of the aeration oxidation tube. The aeration-boosting deep oxidation device is characterized in that an aeration barrel is installed at the tail end of the aeration oxidation tube; air spraying holes are evenly distributed in the barrel wall of the aeration barrel; and a boosting and accelerating spraying tube is arranged at the front end of the aeration barrel. According to the utility model, the air spraying holes formed in the barrel wall of the aeration barrel can spray the air all around in a diffusion manner, so that the contact area between the oxidation air and the desulfurized slurry is increased; and the boosting and accelerating effect of an outlet is realized by utilizing a spraying tube device, so that the oxidation rate in a desulfurized slurry pool is increased, and the content of calcium sulfite in the desulfurized slurry is reduced greatly. Therefore, the aeration-boosting deep oxidation device prevents a spraying system and a fog removing system from being blocked due to scaling generation caused by desulfurized products, and also solves the problems of slow precipitation rate, difficulty in dehydration and the like of the desulfurized products.
Description
Technical field
The utility model belongs to the desulfurization slurry aeration supercharging device of wet type desulfurizing equipment, particularly desulphurization plant.
Background technology
The lime/lime stone wet fuel gas desulfurizing technology is steel mill's sintering furnace sulfur removal technology commonly used; Oxidation technology commonly used has two kinds of forced oxidation and autoxidations in this technology; Because there are many weak points such as fouling and obstruction in autoxidation technology; Influencing the normal operation of whole system, is main with forced oxidation mainly with domestic lime/lime stone wet fuel gas desulfurizing technology at present in the world.But, though forced oxidation device commonly used has now solved many deficiencies of autoxidation technology to a certain extent, but still exist oxidation depth not enough, be prone to fouling and stop up, deficiencies such as the desulfurization product settling rate is slow, dehydration difficulty.
The utility model content
Exist oxidation depth not enough in order to overcome existing forced oxidation equipment; Being prone to fouling stops up; Deficiencies such as the desulfurization product settling rate is slow, dehydration difficulty; The utility model provides a kind of desulfurization slurry aeration supercharging deep oxidation device, and this desulfurization slurry aeration supercharging deep oxidation device not only can improve oxidation depth can also solve problems such as the desulfurization product settling rate is slow, dehydration difficulty.
The utility model solves the technical scheme that its technical problem adopted: a kind of desulfurization slurry aeration supercharging deep oxidation device; Comprise the aeration oxidation tube of upper end for the oxidation air inlet; This aeration oxidation tube is fixed in the desulfurizing tower by bracing frame; It is characterized in that: described aeration oxidation tube end is equipped with aeration cylinder, and the aeration cylinder barrel is provided with equally distributed gas jetting hole, and the aeration cylinder front end is the booster and speed-increasing jet pipe.
Described aeration cylinder diameter is big 1.1 times than the aeration oxidation tube.
The diameter of described gas jetting hole is 1.2cm.
Described booster and speed-increasing jet size is 0.53 times of aeration cylinder, and its gas outlet and axis angle are 45 degree.
The beneficial effect of the utility model be since the aeration cylinder barrel of this supercharging device be provided with gas jetting hole to around spread injection air; Increased the contact area of oxidation air and desulfuration solution; The Effuser device booster and speed-increasing is adopted in outlet; Increased oxidation rate in the desulfurization slurry pond, significantly reduced the content of calcium sulfite in the slurries, reached the solution desulfurization product systems such as spray, demist are caused the fouling obstruction and the purpose of problems such as the desulfurization product settling rate is slow, dehydration difficulty.
