Precise Positioning Laser Welded Pillow Plate Reduces Weld Corrosion Unique Molding Process

Precise Positioning Pillow Plate Reduces Weld Corrosion Unique Molding Process

Overview:

The material selection of the bulging plate is rich and varied, covering carbon steel plates, various types of stainless steel plates, ND steel plates, titanium alloy plates, etc. Different materials give the plates different characteristics. For example, the bulging plate made of stainless steel has good corrosion resistance and can work stably in an environment with corrosive media; the titanium alloy has both high strength and high and low temperature resistance. During the manufacturing process, advanced laser welding technology is used to achieve high-precision connection, and then the welding stress is eliminated through bulging technology, which ensures the reliability of the plate under various working conditions, so that it can adapt to the heat exchange needs from conventional industrial production to special environments.

Brief  Introduction:

In view of the characteristics of flue gas from high-salt wastewater incineration (containing 3-5 times the amount of sodium chloride/sulfate particles as conventional dust, which is prone to Cl⁻ stress corrosion), the modular plate heat exchanger improves the bulging plates and optimizes the flow channel design (channel height 25-35mm, corrugated plates 30°-45° overlap), increasing the dust flow rate to 0.8-1.2m/s (supercritical value 0.5m/s), achieving a reduction in deposition rate of more than 60%.

Product Parameters:

Advantages:
(1) ‌Adaptation to medium and high temperature dust and corrosive media‌:
‌Flue gas inlet 458℃‌, outlet 338℃, S30408 ​​material resistant to high temperature salt corrosion, wide channel design to avoid dust caking, suitable for complex media after waste liquid incineration.Cold side air temperature rises to 220℃‌ (heat load 1380kW), significantly reducing subsequent treatment energy consumption.

‌

(2) ‌Medium flow and resistance balance optimization‌:
‌Flue gas flow 28,446 Nm³/h‌, cold side 25,400 Nm³/h, flow channel design takes into account dust passability and heat exchange efficiency.Hot side resistance 300Pa, cold side 1000Pa‌, pressure drop balance is achieved through plate corrugation optimization, reducing fan energy consumption.

‌

(3) ‌Long-term operation stability‌:
The wide channel reduces the cleaning frequency, combined with the corrosion resistance of S30408, reduces maintenance costs, and is suitable for continuous production of chemical wastewater scenes.
