Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization equipment, in particular to a lime digestion tank used for flue gas desulfurization. Background Art

[0002] Flue gas desulfurization refers to the removal of sulfur oxides from flue gas or other industrial waste gas. The main method is to use a special lime digestion tank for desulfurization treatment. Its main function is to purify industrial waste gas and prevent sulfur oxides from polluting the air.

[0003] The existing lime digestion tank for flue gas desulfurization still has some problems during use. First, when the digestion tank is mixed and stirred by a stirring mechanism, the lime injection pipe is prone to cause blockage of the pipe wall. The existing part directly punches and cleans the pipe wall through a pressurizing mechanism. This method is not only costly, but also easy to damage the inside of the pipe wall. It is difficult to clean at any time and the overall convenience of use is low. Secondly, the existing water injection is carried out through a single water injection pipe, which is easy to cause lime to block the pipe mouth, affecting the effect of water injection and mixing, and also affecting subsequent use.

[0004] Therefore, we propose a lime digestion tank for flue gas desulfurization to solve the above problems. Utility Model Content
