Shaoxing a chemical plant in production non-ferrous metals, copper, nickel and other products produce waste water after again by evaporation crystallization get by-product of zinc sulfate, waste water per day 80 tons.

    Zinc sulfate properties:

    Pure zinc sulfate in the air in the same yellow long storage, on the dry air and lost water into white powder.There are a variety of hydrate: at 0 °C and range and water balance for seven water stable hydrate zinc sulfate, 39-60 °C for 6 in water zinc sulfate, 60-100 °C water projects for zinc sulfate.When heated to 280 °C of hydrate completely lose gesso, 680 °C for sulfuric acid decomposition when oxygen zinc, more than 750 °C further broken down, and the last in the 930 °C or so into zinc oxide and sulfur trioxide formation.

    Zinc sulfate evaporation crystallization device :

    Industrial production for most zinc sulfate zinc sulfate and seven water water zinc sulfate, zinc sulfate into white crystalline, particle or powder.

    Zinc sulfate evaporation mould is according to the property of zinc sulfate forced circulation by evaporation mould, zinc sulfate solution will be in certain temperatures evaporation and concentration, to remove most of the water, and then will concentrate cooling crystallization get zinc sulfate crystals.
