Embodiment Construction
[0051] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0052] Such as figure 1 As shown, a passivated lime reverse passivation process, which includes quicklime grinding, two-fluid atomization injection, reverse injection, final passivation steps,
[0053] 1), quicklime grinding
[0054] The grinding of quicklime is composed of a mill-air separation system, and the specific process features are as follows:
[0055](1) Select raw lime with a particle size of 20-40mm, and send it to the Raymond mill for grinding through the feeding and conveying mechanism; select the excitation electric vibration feeder for feeding, the frequency is adjustable from 0-50Hz, and the feeding amount is 0-12t / h;
[0056] (2) Set the frequency of the mill separator to be adjustable from 0-50Hz, the passing rate of 325 mes...
