Problems solved by technology
[0007] To sum up, at present, large-area aeration and a large number of seawater neutralization devices are used to remove sulfur dioxide from flue gas with seawater. The general disadvantages are that the equipment occupies a large area, consumes a lot of power, and has low oxidation efficiency. Low ability to control heavy metal content

Embodiment Construction
[0015] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] like figure 2 As shown, the whole restoration system of the present invention is arranged in a pool body, and the mixing pool 2, the primary aeration pool 3, the flocculation pool 12, the settling pool 13, the secondary aeration pool 5, and the discharge pool are sequentially separated by interlayers in the pool body. 7. A stirring device 9 is installed in the mixing tank 2, an aeration head is installed in the primary aeration tank 3 and the secondary aeration tank 5, and the aeration time of the desulfurized seawater in the primary aeration tank is 5-10 minutes, and the aeration gas The water ratio is 15:1-20:1. The lower part of the mixing tank 2 is equipped with a mixing tank slag discharge pipe 10, which is regularly pumped and discharged; the lower part of the sedimentation tank 13 is connected with the flocculation tank...

The invention discloses a recovery system and a recovery technology of desulfuration seawater, wherein the whole recovery system is arranged in a tank body; a mixing tank, a primary aeration tank, a flocculating tank, a sedimentation tank, a secondary aeration tank and a discharge tank are orderly divided in the tank body by partition layers; a stirring device is installed in the mixing tank; an aerator is installed in each of the primary aeration tank and the secondary aeration tank; a residue discharge pipe is installed on the lower part of the mixing tank; the lower part of the sedimentation tank is communicated with the flocculating tank; a supernatant liquid is communicated with the secondary aeration tank; the bottom part of the sedimentation tank is provided with the other residue discharge pipe; and a part of incompletely-reacted filter residue can enter a batch feeding tank through the residue discharge pipe for cyclic utilization. The recovery system and the recovery technology of the desulfuration seawater have the advantages and the effects that after treatment on the after-desulfuration seawater by the recovery system and the recovery technology of the desulfuration seawater, not only can the seawater desulfurization degree and the seawater desulfurization capacity be improved, but also the adjustment on pH and the removal of heavy metal are facilitated; in addition, the treatment on wastes through other wastes and the two-way treatment are realized; and due to the characteristics of step-by-step-oxidation, convenience in operation, low energy consumption and high efficiency, the seawater recovery system provided by the invention can be applied to all seawater desulfurization technologies.
Description
technical field [0001] The invention belongs to the technical field of seawater desulfurization of industrial flue gas, and in particular relates to a restoration system and restoration process of desulfurization seawater. Background technique [0002] Flue gas seawater desulfurization is to use the natural alkalinity of seawater to remove SO in flue gas 2 . Depending on whether other chemical absorbents are added, seawater desulfurization processes can be divided into two categories. One is the process of using pure seawater as absorbent, and the other is adding a certain amount of lime to seawater to adjust the alkalinity of the absorption liquid. [0003] Seawater is usually alkaline, with a general pH value between 7.5 and 8.3. The soluble salts in seawater can generally be transformed into their acidic salts, so the ocean is a huge buffer system with natural alkalinity. The natural alkalinity of seawater can restore the pH value of desulfurized seawater, which not on...
