Title: METHOD AND SYSTEM FOR RECOVERING ANTIFREEZE FROM A DUST PREVENTION SYSTEM OF A MINERAL MATERIAL PROCESSING PLANT
Abstract:
System for recovering antifreeze from a dust prevention system of a mineral material processing plant, comprising an antifreeze tank (103); a pump (101) for circulating water and/or antifreeze; a first valve (114) configured to connect to a water inlet (113) and/ or antifreeze tank (103) to the pump (101); a nozzle manifold (102) connected to the pump (101); a second valve (120) configured to connect the nozzle manifold (102) to the antifreeze tank (103) and/or a third valve (118); and a control system for operating according to a method comprising sucking water using a pump (101) from a water inlet (113) via a first valve (114) displacing the antifreeze via a nozzle manifold (102) into an antifreeze tank (103) until the water reaches a second valve (120); and connecting the second valve (120) to a third valve (118) to allow circulation of water in the system.
