Abstract

The invention relates to a continuous preparation system for lime slurry having a fixed concentration, and solves the problem that the prepared lime slurry is insufficient by using a large smoke semidry deacidifying process. The prepared lime slurry is delivered to a rotary atomizer through the system. The system comprises a lime cabin of which the lower part is provided with an activating hopper; the lime cabin is connected with a curing tank through a feeder; the curing tank is also connected with a tap water inlet tube; an outlet of the curing tank is connected with a storage tank through a vibrating filter; and the storage tank is connected with a lime slurry pump. The system is characterized in that: the curing tank is divided into two curing chambers through a chamber-dividing clapboard; and the two curing chambers are provided with a stirrer respectively.

Description

(1) Technical field [0001] The invention relates to the technical field of waste incineration power generation and flue gas desulfurization engineering of blast furnace sintering machines in steel mills, in particular to a constant-concentration lime slurry continuous preparation system. (2) Background technology [0002] At present, there are many forms of flue gas desulfurization process for waste incineration power plants and blast furnace sintering machines in steel mills, one of which is the rotary spray semi-dry flue gas desulfurization process. Lime slurry neutralizes the harmful acid gases in the flue gas. The original constant concentration lime slurry preparation process is prepared in batches, and the prepared lime slurry is stored in a storage tank with a stirring device. This process can meet the requirements for the small demand for lime slurry, but for lime slurry In the application of flue gas deacidification with a large demand for pulp, a storage tank with...
