Lime slurry preparation device

Abstract

The invention relates to a lime slurry preparation device. The lime slurry preparation device comprises a preparation tank, a stirrer, a turbulent flow assembly and a controller, wherein the stirrer is arranged at the top of the preparation tank and penetrating through the preparation tank, the turbulent flow assembly is arranged at the inner wall of the preparation tank, and the controller is electrically connected with the stirrer; the turbulent flow assembly comprises a spoiler and a supporting rib plate, the supporting rib plate is fixed on the inner wall of the preparation tank, the spoiler is fixedly connected with the supporting rib plate, and an interval is formed between the spoiler and the inner wall of the preparation tank; an included angle between a tangent line at a connection point of the supporting rib plate and preparation tank and the supporting rib plate is 70-80 degrees. The lime slurry preparation device strengthens the mixing effect of lime powder and water, improves the preparation efficiency of the lime slurry, and has good safety.

Description

technical field [0001] The invention relates to a stirring device, in particular to a lime slurry preparation device. Background technique [0002] The flue gas desulfurization system usually uses lime as the desulfurization absorbent, and the desulfurization agent usually needs to mix lime powder and water to prepare a lime slurry with a certain concentration. Add lime powder to the water, most of the lime powder will float on the water surface, and it is necessary to mix the lime powder and water thoroughly through constant stirring. If the stirring force is too large, it will cause the lime slurry to splash everywhere, causing pollution to the surrounding environment; if the stirring force is insufficient, the water surface will not form a turbulent state, it will be difficult for the lime powder to mix with the water quickly, and the preparation time of the lime slurry will be extended, and it is easy to Causing lime agglomeration in the preparation tank. [0003] Ther...

AI Technical Summary

Problems solved by technology

If the stirring force is too large, it will cause the lime slurry to splash everywhere, causing pollution to the surrounding environment; if the stirring force is insufficient, the water surface cannot form a turbulent state, and it is difficult for the lime powder to mix with the water quickly, and the preparation time of the lime slurry is prolonged and it is easy to Phenomenon that causes lime agglomeration in the mixing tank

[0003] Therefore, when the existing lime slurry configuration device configures the lime slurry, either the stirring force is too large to cause the slurry to splash, or the stirring force is too small to cause uneven stirring.
