Abstract

PURPOSE: To form Ca(HCO3)2 useful in purification of a sea area for ocean culture by press.-feeding CO2 gas into cylindrical container rotating at a high speed in water to dispersion-dissolve the gas in the water in the form of fine gas bubbles through the side wall of the container and by simultaneously charging powder CaCO3 or slaked lime.
CONSTITUTION: Rotary table 5 set at the bottom of dissolving water tank 3 is rotated at a speed of 500rpm or more with electromotor 11 through transfer mechanism 12, and CO2 gas is press.-fed through hollow rotary shaft 6. The gas enters CO2 gas dispersing container 7 rotating at a high speed, and it is released into the water from the lower periphery of container 7, finely divided with a film formed along the cylindrical side wall, and uniformly dispersed in the water in the form of water sol. gas bubbles. On the other hand, powder CaCO3 or the like is mixed into the water in tank 3 from hopper 1 through charger 2, forming an aq. soln. of Ca(HCO3)2 according to the following equations: CaCO3+CO2+H2O=Ca(HCO3)2 and Ca(OH)2+ 2CO2=Ca(HCO3)2.
