ガスの脱硫処理を行うものである。2. Description of the Related Art There is a wet desulfurization device as a device for removing sulfur oxides contained in a gas to be treated such as exhaust gas from a combustion device. The desulfurization device is for performing desulfurization treatment of the gas to be treated by bringing the absorbing liquid and the gas to be treated into gas-liquid contact to absorb and remove sulfur oxide in the gas.

処理ガスとを接触させて被処理ガスの脱硫処理を行う。There are some absorbents such as a slurry in which an absorbent such as calcium carbonate is dissolved, but it has been proposed to use inexpensive seawater. That is, the desulfurization device is often constructed near the sea, and if a large amount of seawater can be used, desulfurization can be performed at low cost. For example, as shown in FIG. Seawater, which is an absorbing liquid, is sprayed and dropped, and the sprayed seawater and the gas to be treated are brought into contact with each other to desulfurize the gas to be treated.

る必要がありこれを安価に行いたい。By the way, in the above desulfurization apparatus, it is proposed to return the seawater (absorption liquid) obtained by desulfurizing the gas to be treated to the sea, but if it is returned to the seawater as it is, the sulfur oxides are absorbed. Since it has been acidified, the acidification of seawater and the increase of COD are promoted, and water pollution significantly progresses. In this way, only the part of environmental pollution was transferred from air pollution to water pollution, so it is necessary to treat seawater after desulfurization, and we would like to do this at a low cost.

And a seawater treatment unit for oxidizing and neutralizing the seawater by introducing air into the treatment container containing calcium carbonate and blowing air into the seawater to fluidize the calcium carbonate.

行える。In the absorption tower, the gas to be treated comes into contact with seawater, the sulfur oxides in the gas are absorbed and removed by the seawater, and the gas to be treated is desulfurized. The seawater after the desulfurization treatment is introduced into the treatment container of the seawater treatment unit, is oxidized by the air blown into the seawater to reduce COD, and is neutralized by calcium carbonate. At this time, since the calcium carbonate is fluidized by the air, the contact efficiency of the calcium carbonate with seawater is good, and therefore the calcium carbonate for neutralization can be sufficiently neutralized even with a large particle having a diameter of, for example, about 10 mm. Therefore, it becomes possible to use an inexpensive one. Therefore, seawater after desulfurization can be oxidized and neutralized at low cost.

The processing container 12 is formed, for example, in a cylindrical shape, and the inside thereof is partitioned by the overflow plate 14 into two tanks, that is, a processing portion 15 and a processing liquid inflow portion 16. The processing section 15 has a larger volume than the processing liquid inflow section 16,

An air dispersion plate 19 is provided. A large number of air holes 20 are provided on the entire surface of the air distribution plate 19, and the air supplied below the air distribution plate 19 is distributed almost uniformly in the processing unit 15 by passing through the plurality of air holes 20. It has become. The amount of air blown into should be an amount containing approximately 2-3 times more oxygen than SO 2 in the gas. The air dispersion means is for dispersing the air in the processing unit 15, and is not limited to the air dispersion plate 19, and for example, as shown in FIG. It is also possible to disperse the air by arranging a plurality of in parallel in the processing unit 15 at a predetermined interval.

を少なくすることはいうまでもない。Now, seawater is sprayed from the spray nozzle 8 into the absorption tower 1 by the seawater pump 9 through the seawater line 10, and the exhaust gas (gas to be treated) is introduced into the absorption tower 1 from the inlet 4. As a result, the sprayed seawater and the gas to be treated come into gas-liquid contact mainly in the packed bed 7, and the sulfur oxide (SO 2 ) in the gas is absorbed and removed by the seawater (H 2 O + SO 2
→ H 2 SO 3 ) and the gas to be treated is desulfurized.
At this time, the spray amount of seawater is adjusted so that the liquid gas ratio (L / G) is 20 to 25 liters / m 3 or more. L / G like this
By setting 20 to 25 liter / m 3 or more, 90% or more of the sulfur oxides in the gas can be sufficiently removed with seawater even without an absorbent. Needless to say, when the removal efficiency is low, the liquid-gas ratio is reduced.

Is guided to the lower part in the processing unit 15. Air is blown into the seawater from the air line 18 to oxidize the seawater. At this time, the air is almost uniformly dispersed by the air dispersing means, for example, the air dispersing plate 19, so that the seawater is sufficiently oxidized and C

ができる。Further, the seawater which has become acidic by absorbing SO 2 is contacted with the calcium carbonate 22 and neutralized. On this occasion,
Since the calcium carbonate 22 is fluidized by air, the contact efficiency between the calcium carbonate 22 and seawater is improved, and the calcium carbonate 22 for neutralization has, for example, a diameter of 10 mm.
Neutralization can be sufficiently performed even if the degree and particle size are large. Therefore, it is possible to use calcium carbonate, which is cheaper than the one (several tens of μm) used as the absorbent in the wet desulfurization device.

後の海水の酸化と中和を安価に行える。In this way, the desulfurization treatment of the gas to be treated is performed using the seawater, and the seawater after the desulfurization treatment is subjected to the seawater treatment unit 13.
Since it is returned to the sea after being oxidized and neutralized by the method, it does not pollute the environment even if seawater is used as the absorbing solution, and the oxidation and neutralization of the seawater after desulfurization can be performed at low cost.

The portion 32 is divided into two so that the seawater treated by the partition plate 34 overflows into the treatment liquid inflow portion 33. Other configurations such as the air dispersion means of the other processing container 30 are the same as those of the processing container 12 described above. A branch line 35, which is a branch of the seawater discharge line 11, is connected to the two treatment parts 32a and 32b so that the seawater after desulfurization treatment flows in, and the treatment liquid inflow part 33 is connected to the treatment liquid inflow part 33.
