Description
Technical Field
The invention belongs to the technical field of flue gas desulfurization, and particularly relates to a flue gas desulfurization device for sintering by a sodium-calcium double-alkali method.
Background
Sulfur dioxide contained in the flue gas can cause very serious pollution to the atmospheric environment, seriously destroy the ecological balance, cause great harm to the health of animals, plants and human beings, generate acid rain to a great extent, corrode and destroy buildings, and seriously affect the ecological environment and the living environment. Therefore, related treatment technologies are continuously researched and developed by related departments in order to effectively reduce the harm caused by sulfur dioxide. At present, the technical means for treating sulfur dioxide pollution is mainly flue gas desulfurization, and in industry, the technical means is mainly a wet desulfurization technology. Among them, the wet desulfurization technique has the advantages of high desulfurization efficiency and high reaction speed, and is widely applied to the desulfurization field.
The wet flue gas desulfurization mainly refers to desulfurization treatment and desulfurization product treatment performed in a wet state by a slurry absorbent, a liquid absorbent, and the like. The desulfurization method has the advantages of high desulfurization efficiency, high reaction speed and the like, but in the development process, the problems of easy scaling of equipment, incapability of running due to blockage of equipment and pipelines in severe cases, large engineering investment and high running cost exist. The mature wet desulphurization technology mainly comprises dual-alkali desulphurization, calcium-based desulphurization, ammonia desulphurization, magnesium-based desulphurization and the like.

On the other hand, the desulfurization product is discharged into a regeneration tank to be reduced and regenerated by calcium hydroxide, and the regenerated sodium-based desulfurizer is pumped back to the desulfurization tower to be recycled.
In the practical application process, because solid-liquid separation is generally carried out by adopting a step-by-step sedimentation tank for sedimentation during solid-liquid separation, two-phase media are difficult to completely separate, and returned circulating spray liquid still contains solid-phase particles such as gypsum and the like, serious scaling and blockage of system equipment and pipelines are caused, the system equipment cannot normally operate, and great troubles and troubles are brought to users.
