Technical Field

The invention relates to the field of hydrometallurgy, in particular to a cooling tower spray pipe of a new liquid and/or electrolyte circulating cooling system in zinc hydrometallurgy.

Background

In the process of zinc hydrometallurgy, the new liquid (zinc sulfate solution) needs to be cooled to remove calcium and magnesium before entering an electrolytic system, so that the influence on the electrolytic process is reduced, plate burning is avoided, the electric efficiency is improved, and the direct current unit consumption is reduced, therefore, the cooling of the new liquid is of great importance. At present, the cooling mode of new liquid is cooling tower spray cooling, but has the problems of large nozzle resistance, easy crystal blockage, frequent crystal cleaning (once cleaning every week), large cleaning difficulty (needing to be disassembled for cleaning), poor cleaning site environmental sanitation (cleaning an outflow pollution site), poor cooling effect (needing to continuously cool a plurality of cooling towers) and the like. In addition, the silicon carbide nozzle is brittle and easy to break, needs to be replaced frequently, is expensive, and increases the production cost.

It can be seen that there remains a need for improvements in existing cooling tower spray headers.
