The invention relates to the technical field of
calcium formate production, in particular to a
calcium formate efficient evaporative
crystallization method which comprises the following steps: S1, mixing reaction; s2, removing impurities; s3, evaporative
crystallization; s4, centrifugal
drying; and S5, cooling and packaging. The method has the advantages that the whole process is simple, the production cost and the labor intensity are reduced, large-scale
continuous production is easy to realize, the content of the produced
calcium formate product is 99% or above, the purity is high, and the color is pure white; the triple-effect
evaporation technology is adopted,
energy consumption is reduced, the effects of
energy conservation and emission reduction are achieved, meanwhile, crystals which are evenly distributed and large in particle size can be obtained through the last-effect DTB crystallizer, follow-up filtering and
drying are facilitated, and
energy consumption in the follow-up process can be greatly reduced; in the packaging process, the crystals are introduced into a cooler to be cooled and then conveyed to a cooling
cyclone separator, the temperature of the crystals is reduced to 40 DEG C, it is guaranteed that particles are uniform and cannot be hardened, the quality is optimized, and the
operation safety degree is also improved.
