Aiming at the problem of easy scaling in heat circulation water of plate heat exchanger,the effect of reducing scaling is explored by optimizing the design of heat transfer plate,gasket,compression device and support structure.The heat transfer efficiency,sealing performance and structural stability of the plate heat exchanger are significantly improved by using the trapezoidal corrugated heat transfer plate and the three-layer composite sealing gasm,combined with the hydraulic automatic regulation system and the modular support structure.The experimental results show that the optimized heat exchanger reduces the scale by 65.8%,increases the heat transfer efficiency by 5.7%,and reduces the gasket leakage rate to 0.008 mL·min-1 after 30 days of operation,which verifies the effectiveness of the structural optimization.
