SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a fountain flue gas desulfurization tower, flue gas desulfurization is thorough, and desulfurization effect is good.
The utility model discloses a realize through following technical scheme: the utility model provides a fountain flue gas desulfurization tower, includes the tower body, reaches the circulating pump be connected with opposite side and establishes the exhanst gas outlet at the tower body top with the flowing back pump that tower body lower part one side is connected, tower body mid-mounting has a plurality of air inlet baffles, adjacent two the mutual reverse setting of air inlet baffle's air intake, the top of air inlet baffle is equipped with the shower, install a plurality of showerheads on the shower, the shower passes through circulating line and connects the circulating pump, the top of air inlet baffle is equipped with packing layer and defroster in proper order, the defroster is double-deck setting and is the arc.
And an absorption liquid distribution pipe is arranged between the packing layer and the demister.
The tower body and the air inlet partition plate are made of carbon steel, austenitic stainless steel or duplex steel materials.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses an installation a plurality of air inlet baffles, the mutual reverse setting of air intake of adopting two adjacent air inlet baffles for the velocity of flow of flue gas reduces and the flow improves, and then improves the time of shower head spun desulfurization thick liquid and flue gas contact, and the flue gas is longer with thick liquid chemical reaction time, and the flue gas mixes more fully with the thick liquid, and flue gas desulfurization is more thorough.
2. The utility model discloses an adopt the defroster bilayer and for the arc design, increased the area of contact of fog drop and defroster, improved the efficiency of getting rid of fog drops such as containing sulphuric acid, sulfate, sulfur dioxide.
Drawings

Detailed Description
Figure 1 shows a fountain flue gas desulfurization tower as in the drawings attached to the description, including tower body 1, the flowing back pump 2 of being connected with tower body 1 lower part one side and the circulating pump 3 of being connected with the opposite side and establish the exhanst gas outlet 12 at tower body 1 top, tower body 1 lower part one side is equipped with flue gas inlet 4, tower body 1 mid-mounting has a plurality of air inlet baffles 5, the mutual reverse setting of air intake of two adjacent air inlet baffles 5, the top of air inlet baffle 5 is equipped with shower 6, install a plurality of shower heads 7 on the shower 6, shower 6 passes through circulating pipe 8 and connects circulating pump 3, the top of the air inlet baffle 5 of top is equipped with packing layer 9 and defroster 10 in proper order, defroster 10 is the double-deck setting and is the arc.
An absorption liquid distribution pipe 11 is arranged between the packing layer 9 and the demister 10.
The tower body 1 and the air inlet partition plate 5 are made of carbon steel, austenitic stainless steel or duplex steel materials.
As shown in figure 1, flue gas with the temperature of 120-160 ℃ enters a tower body 1 from a flue gas inlet 4 of a desulfurization tower, the flue gas rises along the tower body 1 in the tower body 1, firstly, the flue gas passes through a spraying area, the flow velocity of the flue gas is reduced under the action of a plurality of air inlet partition plates 5, the flow direction is changed left and right, the flow is improved, the flue gas is in full countercurrent contact with desulfurization slurry sprayed by a spray header 7 on a spray pipe 6, heat exchange and mass transfer absorption are carried out, the contact time of the desulfurization slurry and the flue gas is further prolonged, the temperature of the flue gas is reduced to 50-60 ℃, pollutants such as SO 2, SO 3, HCl, HF and the like in the flue gas are removed, most of dust is removed, the flue gas continues to rise after passing through the spraying area, enters a packing layer 9, the flue gas continues to pass through a demister 10 after being, entrained fog drops are removed, because the demister 10 is arranged in a double-layer manner and is arc-shaped, the contact area between the fog drops and the demister is increased, the efficiency of removing the fog drops is improved, the fog drops are discharged through the flue gas outlet 12, the absorption liquid of the packing layer 9 is unsaturated solution and is uniformly distributed on the packing through the absorption liquid distribution pipe 11; the absorbed absorption liquid is discharged out of the desulfurizing tower through a liquid discharge pump 2 for recycling;
the desulfurization slurry sprayed by the spray header 7 on the spray pipe 6 of the desulfurization tower is dripped into the bottom of the tower body 1 to be accumulated and then is pumped out from the bottom of the tower body 1 by the circulating pump 3 to be sprayed into the corresponding spray pipe 6 for cyclic utilization.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
