The untreated gas is introduced into the cooling tower 2 from the gas inlet 1 and cooled by the cooling liquid sprayed from the spray nozzle 18 of the cooling liquid spray pipe 7 installed at the upper part of the cooling tower 2. The cooled untreated gas diverts the gas flow from a vertical downward flow to a horizontal flow in the sump 3, so that the cooling liquid mixed with dust is dropped to a sump hopper 15 which is a liquid and dust collecting part and removed. Be perished. This cooling liquid is collected in the cooling tower circulation tank 5, recirculated to the cooling liquid spray pipe 7 by the cooling tower circulation pump 6, and repeatedly used. On the other hand, the untreated gas that has been cooled and dusted is further subjected to removal of finer dust and mist by the sump mist eliminator 4 and introduced into the spray absorption tower 8. In the spray absorption tower 8, the gas flow rate is made uniform and rectified by the gas dispersion plate 9, and part of the sulfur oxide is removed.

l2は吸収塔８の塔径により決められる。The sump 3 of the cooling tower 2 serves as a duct for collecting a cooling liquid in which impurities such as dust in the exhaust gas are mixed and for connecting with a downstream device such as the sump mist eliminator 4. The structural dimensions of this portion have been determined as follows.
That is, the size of the sump hopper 15, in other words, the fifth
In the figure, l 1 ′ (length in the vertical direction of the sump) is given from the turning angle θ 1 of the exhaust gas and the cooling liquid and the sump depth l 3 . Of these, the turning angle θ 1 is determined so that the cooling liquid dropped from the cooling tower 2 does not directly collide with the sump mist eliminator 4. This angle is represented by the angle between this baseline and the straight line connecting point A and point B, with the vertical line from point A at the bottom of the cooling tower as the baseline, and this angle is the gas flow pattern test conducted in the past. It has been determined as 40 to 42 degrees from the result. Further, since the proper gas flow velocity V of the sump mist eliminator 4 is determined for the sump depth l 3 ,
It is calculated according to the amount of passing gas. Also the horizontal length of the sump
l 2 is determined by the diameter of the absorption tower 8.

Therefore, even if it was made larger, no consideration was given to making it compact.

冷却塔サンプ部構造を提供することにある。An object of the present invention is to eliminate the drawbacks of the prior art regarding the cooling tower sump portion structure, improve the mist removal performance of the sump mist eliminator, and provide a compact and economical cooling tower sump portion structure.

を達成している。The present invention, in the cooling tower sump part, the turning angle of the flow of the exhaust gas and the cooling liquid is 30 to 35 degrees, the summing part having the maximum turning angle of 35 to 40 degrees, and a connecting part connecting the sump part and the sump mist eliminator. The above-mentioned object is achieved by providing the bottom part of the above-mentioned section with an upslope toward the eliminator and having an approaching section corresponding to the difference between the turning angle and the maximum turning angle.

ミネータへの飛散流入をなくすものである。In the present invention, making the turning angle (θ 1 ) of the exhaust gas and the cooling liquid smaller than the conventional one (40 to 42 degrees) reduces the length in the vertical direction of the sump, and connects the sump part and the sump mist eliminator. Providing the run-up portion at the bottom of the connecting passage is equivalent to increasing the turning angle of the exhaust gas and the cooling liquid without increasing the length in the vertical direction of the sump. Therefore, the cooling liquid can be collected without increasing the sump hopper. The effect of eliminating the direct collision with the mist eliminator and the upward slope of the approach portion toward the eliminator eliminates the accumulation of slurry and the inflow of slurry into the sump mist eliminator.

より縮小できることが確認された。In FIG. 1 (a), the size of the sump hopper 15, in other words, the factor that influences l 1 is the turning angle θ of the exhaust gas and the coolant.
Since it is decided by one, the result of which was to investigate the track of the cooling liquid in the sump of the conventional actual plant, theta 1 is
It turned out to be 30-35 degrees. In addition, in order to deal with the case of a larger size, a gas flow pattern test was performed using a geometrical similarity model. As a result, it was found that the turning angle of the cooling liquid was 30 to 35 degrees as in the present invention. There was no difference in the pressure loss at the sump and the flow of cooling liquid droplets when compared with the conventional case of 40 to 42 degrees. From this, it was confirmed that the dust removal performance was not inferior to the conventional one and the shape of the sump portion could be reduced as compared with the conventional one.

It was confirmed that θ 2 is 35 to 40 degrees. Therefore, in FIG. 1 (a), (θ
The portion (BC) corresponding to ( 2- θ 1 ) is distinguished from the θ 1 corresponding portion which is directly related to the sump vertical length l 1 as an approaching portion when exhaust gas travels to the sump mist eliminator.

If the slab is installed so as to be inclined upward toward the eliminator, the slurry will not be deposited in this part, and
As shown in FIG. 6B, it was also confirmed that the bottom of the sump portion, that is, the bottom of the sump hopper should have an inclination angle θ 4 of 7 degrees or more with respect to the horizontal to prevent slurry accumulation.

状を限定するものではない。FIG. 3 is a schematic structural diagram of another embodiment of the present invention. In the structure of FIG. 3, the run-up portion corresponding to the turning angle θ 1 of the exhaust gas and the cooling liquid and the maximum turning angle θ 2 and corresponding to (θ 2 −θ 1 ), the slurry accumulation prevention angles θ 3 and θ 4 (θ 4 Is not shown in FIG. 3), which is the same as in FIG. 1, but FIG. 3 further reduces the structure to cope with the case where the desulfurization tower requires a larger size. Therefore, as an additional structural measure, the sump depth at the exit sump ceiling of the cooling tower 2 is 1 /
It differs from FIG. 1 in that a baffle plate 16 for introducing exhaust gas and cooling liquid of 10 or less is provided. In this structure, the baffle plate length l 4 is about 10 with respect to the sump depth l 3.
%, It was confirmed that the pressure loss during the gas flow pattern test was the same as that of the conventional type. Moreover, since the angles θ 1 to θ 4 and the sump depth l 3 are the same as those in the case of FIG. 1 , in the case of FIG.
Corresponding to the fact that the starting point A of θ 2 is lowered by the baffle plate length l 4, the sump longitudinal length l 1 can be reduced. The shape of the baffle plate is preferably a triangular shape as shown in FIG. 3, but the shape is not limited to a simple plate shape.

Since the accumulation of slurry in this portion can be prevented, the mist removing performance of the sump mist eliminator can be improved.
以上により、前記した本発明の目的が達成できる。 From the above, the above-mentioned object of the present invention can be achieved.
