Concave And Convex Pillow Plate Heat Exchanger
Advanced heat exchanger featuring corrosion resistance and strong adaptability for industrial applications.
Product Overview
Pillow plate heat exchangers offer significant advantages over traditional designs. Compared to shell and tube heat exchangers, they are 70% smaller in size, 50% lighter in weight, and provide 2-3 times higher heat transfer coefficient. The fully welded structure eliminates leakage risks associated with gasket plate heat exchangers and operates across a wider pressure range. The unique pillow-shaped flow channel design optimizes both heat transfer efficiency and fluid handling capacity, achieving 1°C approach temperature in small temperature difference scenarios like waste heat recovery.

Key Advantages
Dual-Material Corrosion-Resistant Design
Combined S22053 duplex steel and S31603 stainless steel construction adapts to complex corrosive environments including chloride-containing exhaust gases, extending equipment lifespan.
Low-Temperature High-Efficiency Energy Saving
Cold side inlet temperature of 82°C rises to 188°C after heat exchange, increasing low-temperature waste heat recovery efficiency by 15% and reducing energy consumption costs.
Ultra-Large Flow Processing Capacity
Handles cold side flow of 70,329 Nm³/h and hot side flow of 83,945 Nm³/h, suitable for large-scale exhaust gas purification in 90,000-ton annual acrylic acid production units.
Wide Temperature Range & Precise Adjustment
Hot side temperature drops from 240°C to 150°C while cold side temperature rises by 106°C, maintaining ±2°C temperature difference control accuracy for stable catalytic oxidation.
