The crystal nucleus is suspended in water and is collided by peristalsis and mixed with NaC03And high-hardness water of the NaOH medicament enters the microcrystal grain region from bottom to top, so that the crystal nucleus is in a floating crystallization state. During the flow, NaOH reacts with HC 03-and Ca2+, Mg2+ in water as follows:
CO32-+Ca2+—CaCO3 OH-+HCO3-—CO32-+H2O，
NaOH—OH-+Na+ OH-+Mg2+—Mg(OH)2
