| titleOfInvention | Waste acid addition controlling method of zinc wet smelting cobalt-removing purifying process employing arsenic salt |
| abstract | The invention discloses a waste acid addition controlling method of a zinc wet smelting cobalt-removing purifying process employing arsenic salt. According to the invention, three main elements, which are arsenic salt addition amount, underflow returning rate, and zinc powder addition amount, influencing waste acid addition of the cobalt-removing process employing arsenic salt, are taken into consideration. A waste acid addition mathematical model based on the chemical mechanism of the cobalt-removing process employing arsenic salt and material balance is established by researching. Large time delay of crucial parameters during chemical examination influences accurate waste acid addition. Also, the fluctuations of liquid flow rate and underflow returning rate after copper-removing in the arsenic salt purifying process are large. For improving the self-adaptability of the system, the calculated values of the waste acid addition mathematical model are corrected by using variable universe fuzzy expert rules. According to the invention, BT value wide fluctuations caused by unreasonable addition of waste acid during the cobalt-removing purifying process employing arsenic salt can be avoided, such that outlet cobalt ion qualification rate can be improved, phenomenon of difficult press-filtering or even filter cloth blocking of a press filter is substantially improved, and necessary conditions for realizing stable and optimized operation of the cobalt-removing purifying process employing arsenic salt are created. |
