Definitions
- the present invention relates to a wet flue gas desulfurization apparatus that desulfurizes exhaust gas by bringing it into gas-liquid contact with an absorption liquid in an absorption tower and that can stir the absorption liquid stored in the absorption tower.
- Exhaust gas generated in large-scale combustion facilities, plants, etc. contains sulfur oxides (SO X ) such as sulfurous acid (sulfur dioxide, SO 2 ), so that removal of sulfur oxides (desulfurization) is required. . Therefore, a wet flue gas desulfurization apparatus (hereinafter referred to as “desulfurization apparatus”) that desulfurizes exhaust gas using an absorbing solution containing an alkaline substance such as an alkali metal is widely used.
- the desulfurization apparatus employs a lime gypsum method, a magnesium hydroxide method, a sodium hydroxide method, an ammonia absorption method, and the like. In particular, the lime gypsum method is adopted in many desulfurization apparatuses.
- a lime stone slurry prepared by suspending limestone (calcium carbonate, CaCO 3 ) in water is often used as an absorbing solution. It is used.
- an absorption liquid having a relatively high viscosity is used in the desulfurization apparatus.
- the concentration of the limestone slurry is generally set to about 10 wt% to about 30 wt%. Yes.

Furthermore, since the air pressure generating mechanism supplies air at a high pressure, the structure of the air pressure generating mechanism is complicated. As a result, maintenance of the air pressure generation mechanism becomes difficult, and maintenance of the desulfurization apparatus becomes difficult.
- the propeller and the pneumatic nozzle are configured to start and stop together with these mechanisms mainly in conjunction with the spray mechanism, the oxidation mechanism, and the circulation mechanism. Therefore, when the desulfurization unit is stopped, the circulation mechanism is stopped, so that the absorption liquid stored in the absorption tower does not circulate and becomes non-flowable, and as a result, is stored in the absorption tower. Slurry sedimentation occurs in the absorbent. Immediately after starting the desulfurization apparatus from such a state, the absorbing liquid is not sufficiently stirred by the propeller and the pneumatic nozzle.
