The utility model discloses a novel wet process leaches material heat transfer system. Novel wet process leaches material heat transfer system includes: first heat exchanger, first heat exchanger includes: first casing, the first flitch and the first of go up dividing divides the flitch, and first going up divides the flitch and the first to divide the flitch to turn up the soil along upper and lower orientation interval to establish at the first intracavity that holds, be equipped with heating medium on the wall in first heat transfer chamber and import and export, with establish a plurality of first heat exchange tube at first heat transfer intracavity, the upper end of a plurality of first heat exchange tubes and a plurality ofly firstly go up that through -holes link to each other and lower extremes link to each other with a plurality of first through -holes, and the pressure leaching cauldron, the preceding liquid import of cauldron of advancing of pressure leaching cauldron communicates with first discharge gate. According to the utility model discloses novel wet process leaches material heat transfer system can be effectively, heat liquid before advancing the cauldron for a long time, and the pressure leaching reaction can be carried out effectively, smoothly to advantage such as have that the heating is effectual, long service life, stable, the easy control of the ejection of compact, vibration are little.
