APPARATUS FOR EVAPORATIVE CONCENTRATION OF WATER TO BE TREATED, WHICH USES HOT LIME SOFTENING, AND METHOD FOR EVAPORATIVE CONCENTRATION OF WATER USING THE SAME |
摘要 |
An apparatus for evaporative concentration of water, containing hardness-causing substances, to be treated using hot lime softening, includes: a first evaporator configured to form first concentrated water from the water to be treated by evaporatively concentrating the water by first heat exchange with hot steam; a hot lime softener configured to precipitate and to separate hardness-causing substances contained in the first concentrated water from at least a portion of the first concentrated water from the first evaporator by reaction with lime and configured to remove the hardness-causing substances from the first concentrated water; and a second evaporator configured to form second concentrated water by further evaporatively concentrating at least a portion of the first concentrated water that passed through the hot lime softener by second heat exchange with hot steam. |

1. An apparatus for evaporative concentration of water, containing hardness-causing substances, to be treated using hot lime softening, the apparatus comprising:
a first evaporator configured to form first concentrated water from the water to be treated by evaporatively concentrating the water by first heat exchange with hot steam; a hot lime softener configured to precipitate and to separate hardness-causing substances contained in the first concentrated water from at least a portion of the first concentrated water from the first evaporator by reaction with lime and configured to remove the hardness-causing substances from the first concentrated water; and a second evaporator configured to form second concentrated water by further evaporatively concentrating at least a portion of the first concentrated water that passed through the hot lime softener by second heat exchange with hot steam. |
