In chemical, refining, and other industrial facilities, when the medium temperature exceeds 150°C or the design pressure is higher than 2.5 MPa, the rubber gaskets of traditional detachable plate heat exchangers are prone to aging and failure, leading to frequent shutdowns and material leakage. Plate-shell heat exchangers use fully welded plate packs instead of gasket seals, making them suitable for operating conditions with temperatures up to 400°C and design pressures not exceeding 4.0 MPa, offering a solution to such problems.
The BRQ-160 plate-shell heat exchanger is composed of a plate pack and a shell. The plate-side channels are relatively narrow, while the shell-side channels are wider. The plate pack is a fully welded structure without gaskets, reducing leakage points. When purchasing, please provide the medium composition, inlet and outlet temperatures, design pressure, and flow rate so that the required number of plates and pass arrangement can be calculated, allowing the heat transfer area and pressure drop to match the actual operating conditions.
This model is suitable for scenarios such as reforming units in refineries, synthesis loops in fertilizer plants, steam condensation, and heat transfer oil cooling. For example, in the working condition of steam heating heat transfer oil, the plate-shell heat exchanger can withstand higher temperatures and pressures, reducing unplanned shutdowns caused by gasket aging.
