Abstract
The utility model discloses an oxidation air supply device for a desulfurization tower. The desulfurization tower comprises a tower body, an air inlet, a stirrer, a circulating pump, a spray pipe and an oxidation air supply device, wherein the air inlet is formed in the middle section of the tower body; the lower section of the tower body is connected with the circulating pump; the circulating pump pumps slurry into the spray pipe; the oxidation air supply device comprises an oxidation fan, an air pipe and a vent hole; the oxidation fan is arranged below the air inlet and connected with the air pipe; the air pipe is arranged in the slurry; the stirrer is also arranged around the tower body; the air pipe is of a multi-layer structure; and each layer consists of multiple branch pipes. According to the scheme, by adopting a smaller vent hole and layered branch structure, the air distribution in the slurry is more uniform; and under the drive of the stirrer, the contact between the air and the slurry is more sufficient, thus the oxidation space and oxidation time are guaranteed, and calcium sulfite can be converted into gypsum more efficiently.
Description
Technical field
The utility model relates to the environment protection desulphurization technical field, and desulfurizing tower technology especially is specifically related to be used for the oxidation air feeding mechanism of desulfurizing tower.
Background technology
Lime stone---gypsum method sulfur removal technology is most widely used in the world a kind of desulfurization skill wet desulfurizing process flow chart art, and the flue gas desulfur device about 90% that adopt in the thermal power plant of Japan, Germany, the U.S. adopts this technology.Its operation principle is: agstone is added water make slurries and pump into the absorption tower as absorbent and fully contact mixing with flue gas, calcium carbonate in sulfur in smoke and the slurries and the air that blasts from the tower bottom carry out oxidation reaction and generate calcium sulfate, after calcium sulfate reached certain saturation degree, crystallization formed dihydrate gypsum.The gypsum slurries of discharging through the absorption tower through concentrate, dehydration, make its water content less than 10%, deliver to the gypsum bunker with conveyer then and stack, the flue gas after the desulfurization is removed droplet through demister, pass through the heat exchanger heat temperature raising again after, enter atmosphere by chimney.Because absorption tower inner absorbent slurries circulate repeatedly by circulating pump and contact with flue gas, the absorbent utilization rate is very high, and calcium sulfur ratio is lower, and desulfuration efficiency can be greater than 95%.
The oxidation air device that existing desulfurizer adopts adopts the large aperture more, and one-pipe is carried air in slurries, and air bubble is big and inhomogeneous, and the air time of staying is short, causes the slurries oxidation incomplete easily, also is unfavorable for the generation of gypsum crystal simultaneously.
The utility model content
At the problems referred to above, the utility model aims to provide a kind of oxidation air feeding mechanism of even input air bubble.
For realizing this technical purpose, scheme of the present utility model is: a kind of oxidation air feeding mechanism that is used for desulfurizing tower, described desulfurizing tower comprises tower body, air inlet, agitator, circulating pump, shower and oxidation air feeding mechanism, air inlet is arranged on the stage casing of tower body, the tower body hypomere is connected with circulating pump, circulating pump is drawn into slurries in the shower, and described oxidation air feeding mechanism comprises oxidation fan, air hose, steam vent; Oxidation fan is arranged on the air inlet below, and oxidation fan is connected with air hose, and air hose places slurries; Also be provided with agitator around the tower body; Described air hose is the plural layer structure, and every layer by a plurality of arms compositions.
As preferably, described oxidation fan is provided with two, adopts roots blower.
As preferably, described agitator is provided with four for tiltedly advancing the formula mixer around tower body.
As preferably, described air hose is a double-decker, forms by 3-5 arm for every layer.
The beneficial effects of the utility model are: it is more even to adopt less steam vent and layering branched structure to make that air distributes in slurries, drive by agitator simultaneously, it is more abundant to make that air contacts with slurries, thereby guaranteed oxidation space and oxidization time, made calcium sulfite can be converted into gypsum more efficiently.
Description of drawings
Fig. 1 is the structural representation of air hose of the present utility model;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 2, a kind of oxidation air feeding mechanism that is used for desulfurizing tower, this desulfurizing tower comprises tower body 1, air inlet 2, agitator 5, circulating pump 3, shower 4 and oxidation air feeding mechanism, and this oxidation air feeding mechanism comprises oxidation fan 6, air hose 7, steam vent 8; Air inlet 2 is arranged on the stage casing of tower body 1, and tower body 1 hypomere is connected with circulating pump 3, and circulating pump 3 is drawn into slurries in the shower 4, and oxidation fan 6 is arranged on the air inlet below, and oxidation fan 6 is connected with air hose 7, and air hose 7 places slurries; Also be provided with many agitators 5 around the tower body 1; Described air hose 7 is the sandwich construction of plural number, every layer of a plurality of arm 9 of all telling plural number.
The stirring action of agitator can drive the slurries rotation simultaneously so that liquid slurry is kept suspended state and lamination do not occurred, more fully with slurries in oxygen generation oxidation reaction.As shown in Figure 1, described air hose 7 is a double-decker, all tells 3-5 arm 9 for every layer.For better oxidizing condition is provided, air hose one deck is above mixer, and one deck is below mixer, and it is more even to be arranged so that like this air distributes in slurries.
Described oxidation fan 6 adopts roots blower, is provided with two, and one opens one is equipped with, and roots blower has stability preferably, and 2 equipment are set, and can prevent can't normally provide air when catastrophic discontinuityfailure from occurring.Described agitator 5 is provided with four around the tower body, is provided with all around to guarantee that slurries keep suspended state.Described steam vent diameter is 6-10mm, and original equipment adopts the above steam vent of 12mm usually, and under the equal air-flow, excessive air bubble is unfavorable for the oxidation of slurries.
The beneficial effect that this use is novel, less steam vent and layering branched structure make that air distributes in slurries more even, by the drive of agitator, it is more abundant to make that air contacts with slurries simultaneously, makes calcium sulfite can be converted into calcium sulfate more efficiently.
The above; it only is this novel preferred embodiment; not in order to restriction the utility model, every foundation technical spirit of the present utility model to any trickle modification that above embodiment did, be equal to and replace and improve, all should be included within the protection domain of technical solutions of the utility model.
