Concave And Convex Plates Pillow Plate Heat Exchanger Corrosion Resistance Strong Adaptability

Concave and Convex Plates Pillow Plate Heat Exchanger Corrosion Resistance Strong Adaptability

Overview:

Compared with shell and tube heat exchangers, pillow plate heat exchangers are 70% smaller in size, 50% lighter in weight, and 2-3 times more heat transfer coefficient; compared with gasket plate heat exchangers, the fully welded structure completely solves the leakage risk and has a wider applicable pressure range. Its unique pillow-shaped flow channel design takes into account both heat transfer efficiency and fluid handling capacity, especially in small temperature difference heat exchange scenarios (such as waste heat recovery), it can achieve a 1°C approach temperature and maximize the recovery of low-grade heat energy.

Brief  Introduction:

The core configuration of Jiangsu Ruiding catalytic incineration device is a plate heat exchanger, the cold side of which treats waste gas containing propylene organic matter and aldehydes/organic acid compounds (VOCs concentration 4.2-16.3%LEL), and the hot side is connected to 480-520℃ catalytic post-purification flue gas. Due to the high temperature sensitivity of the catalyst (design temperature ±2℃ control requirement), the integrated waste gas preheating system achieves temperature fluctuation ≤±1.8℃ (GB/T 20109 standard verification).

Product Parameters:

Advantages:
(1) Dual-material corrosion-resistant design‌:
Combined use of S22053 duplex steel + S31603 stainless steel, adapted to more complex corrosive environments (such as waste gas containing chloride ions), extending equipment life.

(2) ‌Low-temperature and high-efficiency energy saving‌:
The inlet temperature of the cold side is only 82℃, which rises to 188℃ after heat exchange, and the low-temperature waste heat recovery efficiency is increased by 15%, reducing energy consumption costs.

‌(3) Ultra-large flow processing capacity‌:
The cold side processing flow reaches 70,329 Nm³/h‌, and the hot side flow reaches 83,945 Nm³/h‌, which is adapted to the large-scale waste gas purification needs of an annual production of 90,000 tons of acrylic acid units.

‌(4) Wide temperature range and precise adjustment‌:
The hot side temperature drops from 240℃ to 150℃‌, and the cold side temperature rises by 106℃‌. The temperature difference control accuracy is maintained at ±2℃‌, ensuring catalytic oxidation stability.

Applcation:
(1) ‌Industrial heat transfer‌: reactor jacket, melting crystallizer, flue gas waste heat recovery
‌

(2) ‌Environmental protection‌: sewage treatment, exhaust gas condensation
‌

(3) ‌Refrigeration system‌: plate ice maker, immersion cooling
‌

(4) ‌Energy equipment‌: fuel gas heat exchange, thermal oil circulation
