Problems solved by technology

[0004] When making an alkaline solution, lime is generally used. Lime is not an alkali. Calcium hydroxide formed by dissolving quicklime in water is an alkali. When using it, lime and water need to be mixed and stirred evenly to make a calcium hydroxide solution. Therefore, it is easy to use. In the prior art, when making calcium hydroxide solution, lime powder and water will be added according to a certain ratio. After stirring for a period of time, calcium hydroxide solution can be obtained, but there are some problems in its use , when making calcium hydroxide solution, lime powder and water are weighed separately, then added, then stirred, and then the solution is collected, the production process is cumbersome, and this process cannot be carried out at the same time, which affects work efficiency

The quantitative lime slurry mixing device comprises a workbench, a discharging mechanism is arranged on one side of the workbench, a quantitative feeding mechanism is arranged on the workbench, and a stirring mechanism is arranged on one side of the quantitative feeding mechanism. The device has the beneficial effects that the device can be used for quantifying, feeding, stirring, discharging and the like at the same time, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a lime slurry quantitative mixing device for flue gas desulfurization. Background technique [0002] In recent years, the state has set strict emission standards for sulfide and nitrogen oxides emitted by iron and steel enterprises. To meet the new national emission standards, iron and steel enterprises must desulfurize the flue gas. [0003] The double-alkali method is that soluble alkali reacts with SO2 in the absorption tower to form soluble salt, and calcium-based desulfurization agent is added outside the tower for regeneration, and after flocculation, precipitation, slag removal and other operations, the clear liquid is returned to the absorption tower to re-SO2 and desulfurize the slag. After oxidation, gypsum is generated for reuse, with a desulfurization efficiency of over 95%, no waste generation, no scaling, reliable operation, low liquid gas...
