HEAT RECOVERY SYSTEM FROM THE ROTOMOLDING MACHINES

摘要

heat recovery system for rotomolding furnaces. comprises a closed water recirculation duct system (d) (a) comprising a heat exchanger (1) mounted at the outlet of the waste and gas overflow chimney (2), which by means of a pump (3) properly coupled to electrically operated valves (v1, v4, v5, v6) and electrically monitored hand valves (v2, v3, v7) make the water recirculate to the ideal temperature by the water trap (4) and the material silo (5) jacketed raw material, all governed by a temperature controller (7) and ensured by an automatic pressure relief valve (8), pressure switch (9) associated with the correct activation of the dampers (10 and 11) according to temperature demand and need operating
