Description
Technical field
The utility model relates to a kind of high-efficiency energy-saving desulfurizing oxidation air pipe.
Background technology
In the limestone/gypsum wet desulfurization system, need adding oxidation air be calcium sulfate with the calcium sulfite forced oxidation, thereby makes calcium sulfate absorb two water and be combined into calcium sulphate dihydrate (being gypsum), just can carry out follow-up processed; In the magnesium method desulphurization system, needing equally to add air is calcium sulfate with the magnesium sulfite forced oxidation, just can carry out follow-up processed.
Wet desulphurization absorption tower is provided with side-feeding mixer at present, and one side is through the disturbance of agitator; Preventing the slurries deposition in the desulfurizing tower, on the other hand, is to sow through agitator; The oxidation air pipeline vertically extend into the front end of agitator paddle; Disturbance through agitator paddle is broken into minute bubbles with oxidation air, gets into the slurries system and reacts.Because the rotating speed of agitator is lower, the degree of crushing of its bubble is lower, causes the utilization rate of oxidation air low, must be through increasing the needs of problems that air capacity solves oxidation air, and like this, the energy consumption of desulphurization system will increase, and operating cost increases.
In addition, the requirement of the desulfuration absorbing tower slurries time of staying is not less than 4min, and in the stock tank of absorption tower under the specific conditions, the crystallization time of gypsum is very long, and required stock tank volume requires enough greatly, so the desulfurizing tower liquid level might be very high.Side-feeding mixer generally is fixed on absorption tower sidewall 1.2m ~ 1.5m place; And extending into the resistance that absorption tower agitator paddle front end must overcome absorbing tower liquid-level, the oxidation air pipe could air be sent in the tower; In this case, the oxidation fan pressure head requires very high, and some project must be provided with the two poles of the earth roots blower could satisfy engineering demand; Therefore cause power consumption to increase, operating cost increases.
Summary of the invention
Be technical deficiency more than solving, the utility model provides a kind of oxidation air utilization rate high, energy-conservation high-efficiency energy-saving desulfurizing oxidation air pipe.
The utility model is realized through following measure:
A kind of high-efficiency energy-saving desulfurizing oxidation air pipe of the utility model; Comprise body; Said body is arranged on the liquid level below in the stock tank of absorption tower, and said body is L shaped, comprises oxidation air transverse tube and oxidation air standpipe; Said oxidation air standpipe vertical connection is at oxidation air transverse tube end and Open Side Down, and said oxidation air transverse tube bottom evenly is provided with the oxidation air wind distributing hole.
Be provided with some laterally side by side support bars in the stock tank of above-mentioned absorption tower, the oxidation air transverse tube of some bodys laterally is placed side by side on the support bar and is perpendicular with support bar.
The below, left side and the below, right side of above-mentioned oxidation air transverse tube are respectively arranged with a deoxygenation air wind distributing hole.
Above-mentioned oxidation air transverse tube is 5m apart from the height of liquid level.
The beneficial effect of the utility model is:
1. simple in structure, convenient making, installation and maintenance; 2. cloth wind is even, and bubble diameter is little, improves the utilization rate of oxidation air; 3. raising reaction speed, reaction efficiency is high, and result of use is good; 4. reduce blower fan and overcome the loss in head that liquid level produces, the blower fan power consumption is low.

Among the figure: 1 oxidation air transverse tube, 2 support bars, 3 oxidation air standpipes, 4 absorption tower agitators, 5 oxidation air wind distributing holes, 6 absorption tower stock tanks.
The specific embodiment
Like Fig. 1,2,3, shown in 4, a kind of high-efficiency energy-saving desulfurizing oxidation air pipe of the utility model comprises body; Body is arranged on the liquid level below in the absorption tower stock tank 6; Body is L shaped, comprises oxidation air transverse tube 1 and oxidation air standpipe 3, and oxidation air standpipe 3 vertical connections are at oxidation air transverse tube 1 end and Open Side Down; Oxidation air transverse tube 1 bottom evenly is provided with oxidation air wind distributing hole 5; Oxidation air wind distributing hole 5 bore size and perforate spacing confirm according to air quantity, generally better for oxidation effectiveness, be respectively arranged with a deoxygenation air wind distributing hole 5 below the left side of oxidation air transverse tube 1 He below the right side.Be provided with some laterally side by side support bars 2 in the absorption tower stock tank 6, the oxidation air transverse tube 1 of some bodys laterally is placed side by side on the support bar 2 and is perpendicular with support bar 2.Absorption tower agitator 4 prevents the slurries deposition through disturbance.
Through oxidation air wind distributing hole 5 air is blown in the stock tank, bubble rises in being blown into stock tank and in stock tank in the whole process more than the liquid level and carries out oxidation reaction, and calcium sulfite is converted into calcium sulfate.Because wind distributing hole is evenly distributed, and the particle diameter of bubble is littler, makes more abundant that its air bubble contacts with slurries, and reaction condition is better.Oxidation air transverse tube 1 leans on oxidation air pipe support fixation in the absorption tower.The end of oxidation air standpipe 3 is uncovered; Purpose is to move the variation of liquid level in order to adapt to the absorption tower, and when no matter being high liquid level and low liquid level, air bubble all can not emerged in uncovered position; All get in the stock tank through oxidation air wind distributing hole 5, its effect mainly is the operation of considering oxidation fan.Distance between oxidation air transverse tube 1 and the liquid level is generally 5m, and like this, the type selecting of oxidation fan is and overcomes liquid level resistance and tower Outer Tube resistance sum, and the pressure head of blower fan is less.
Its operation principle is: major pollutants sulfur dioxide in desulphurization system, sulfur dioxide get into back in the desulfuration absorbing tower and fully contact with medium medium in the tower and be converted into sulfurous acid, again with tower in calcium ion combine generation cigarette calcium sulfate.Because calcium sulfite is follow-up can't be handled, need be translated into gypsum ability subsequent treatment, calcium sulfite need be forced and be oxidized to calcium sulfate like this, and calcium sulfate combines two water to generate gypsum later on.The oxidation air source of the gas is an air, is provided by roots blower, and roots blower heats up after with air pressurized simultaneously; So the blower fan outlet need be provided with the spray cooling device; Air is converted into saturated moist air, enters into oxidation air transverse tube 1, the oxidation air wind distributing hole 5 from oxidation air transverse tube 1 is evenly distributed in the slurries then; It is contacted with slurries fully, reach the purpose of desulfurization.
The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection domain of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
