Technical Field

[0001] The invention relates to the technical field of resource recovery and utilization equipment, and in particular to a highly efficient desulfurization and purification stacking equipment for treating high-concentration sulfur dioxide. Background Art

[0002] The traditional desulfurization system is a single independent equipment. When dealing with high concentration of sulfur dioxide, it is generally arranged in two or three stages in series. This not only takes up a large area, but also has high investment costs and is very uneconomical. When the site provided by the treatment site is limited, the traditional series desulfurization cannot meet the layout requirements of the limited area.

A first-stage return slurry pipe 6 leading to a first-stage circulation pool 14 is arranged below the first-stage equalizing chamber 3; the absorption circulation slurry of the first-stage tower mechanism is sent to the first-stage tower mechanism through the first-stage circulation pump 13, and the absorption circulation slurry is then returned to the first-stage circulation pool 14 through the first-stage return slurry pipe 6.
