3) kiln gas is sent in the mixing solutions in carbonating tower, add temperature to 30 ~ 40 DEG C, add metabisulfite solution at mixing solutions subsequently, leave standstill 10min;
4) by step 3) in mixed solution filter, dry, pulverize, classification obtains purity calcium carbonate;
5) by step 4) in the finished product purity calcium carbonate that obtains add appropriate water, add 1% ~ 2% silane coupling agent, be mix 30 ~ 40min under the condition of 40 ~ 50 DEG C in temperature, add the oxidation inhibitor mixing 10 ~ 20min of 0.3% ~ 0.5% subsequently;
6) finally add the fatty acid promoting agent of 05% ~ 1%, stir dry after 20 ~ 30min, grind to form powder, obtain the high-purity activity calcium carbonate of coating.
Further, described step 3) in kiln gas in containing the carbonic acid gas of 30% ~ 35% concentration.
Further, described step 3) in carbonating tower in send into step 1) in collect carbonic acid gas.
Further, described step 5) in coupling agent be silane coupling agent KH560.
Further, described step 5) oxidation inhibitor be phosphorous acid ester.
Beneficial effect of the present invention: adopt carborization to obtain calcium carbonate, the purity of calcium carbonate can be improved, add sodium sulfate in this process simultaneously and can go out the heavy impurity such as magnesium, barium of calcium carbonate, improve the purity of calcium carbonate, also its colourity can be made whiter, utilize silane coupling agent KH560 and phosphorous acid ester, fatty acid promoting agent to carry out modification to it subsequently, thus add calcium carbonate overall performance.
