Metal smelting heat exchanger

Metal smelting heat exchanger is used to heat or cool corrosive liquids during metallurgy or refining separation of rare metal ores such as non-ferrous metals, precious metals and rare earth metals. The refining of non-ferrous metals, precious metals and rare earth metals includes gold, silver, lead, zinc, copper, bismuth, indium, cadmium, selenium, tellurium, antimony, uranium and other rare metals. Corrosive acids are needed in the purification, refining and recovery of these rare metals, Such as fluosilicic acid, hydrofluoric acid, sulfuric acid, etc., In the process of electrolytic smelting or thermal metallurgy, it is sometimes necessary to heat or cool corrosive liquids, Traditional heat exchangers made of stainless steel, titanium and other metal materials can not have poor corrosion resistance in these acid solutions, Metal smelting heat exchanger made of fluoroplastics is an ideal choice for heating or cooling in metal smelting, refining and recovery

Fluoroplastics have excellent chemical stability and temperature stability, can resist corrosion of various strong acids, strong alkalis and strong oxidants, and can be used in the range of-200 ℃ ~ 250 ℃. Metal refining heat exchanger made of fluoroplastics is a heat exchange equipment which can fully meet the conditions of strong corrosion

Metal metallurgical heat exchanger belongs to non-standard customized products, which are mainly divided into immersion type and shell-and-tube type. Immersion heat exchanger is to immerse the whole heat exchanger in electrolyte for heating or cooling, while shell-and-tube heat exchanger pumps out corrosive liquid through the heat exchanger for heat exchange with cold and hot media, which can be selected by users according to the situation. Our company can optimize the design according to the actual production situation in the process of refining and recovering non-ferrous metals.
