Abstract
The invention relates to a manganese sulfate monohydrate purifying device. A triple-effect condenser is adopted in the purifying device, and the problems that in an existing manganese sulfate monohydrate purifying process, energy consumption is high and production cost is high are effectively solved. A forced circulating pump is arranged at the bottom of the triple-effect condenser and used for preventing materials from producing crystals and scales in a pipe. The condenser is connected with a heater, and therefore waste heat is fully used; the temperature of equal-effect condensate water is decreased after vapor is produced through flashing, and the condensate water returns to a boiler for use; triple-effect flashing is conducted on double-effect condensate water, double-effect condensate water and triple-effect condensate water are mixed and discharged, and therefore evaporating efficiency is improved, and vapor consumption is lowered.
