Chemically Cleanable Plate And Shell Heat Exchanger For Optimal Efficiency

^{DELLOK YONGHUI Chemically Cleanable Plate And Shell Heat Exchanger for Optimal Efficiency}

Introduction:

^{Heat exchangers are mainly innovative applications in the fields of heat transfer and water treatment. Plate heat exchangers are divided into detachable plate heat exchangers, semi welded plate heat exchangers, fully welded plate heat exchangers, plate shell heat exchangers, and tube shell heat exchangers. The company has a large-scale modern production base and has obtained ASME, ISO9001, and CE certifications. It has the qualification for environmental protection professional general contracting and the qualification for manufacturing Class I and Class II pressure vessels.}

^{The AK and AR series detachable heat exchangers, HBR series fully welded heat exchangers, BHR series semi welded heat exchangers, evaporators, condensers, and HK series plate and frame heat exchangers produced are widely used in industries such as petrochemicals, steel, chemicals, electricity, food and beverage, HVAC, shipbuilding, etc. The products are exported to multiple countries and highly praised by customers.}

How it works:

^{The sealing gasket is attached to the heat transfer plate, forming a flow channel to seal the fluid from leaking out. The number of heat exchange plates is determined based on the amount of fluid, the physical properties of the fluid, pressure drop, and thermal conditions. The cover plate prevents the plate from bending due to pressure difference. In the assembly of the board, the surface with gaskets points towards the fixed cover, and each board is suspended alternately in opposite directions. In this way, the two liquids can flow and transfer heat in their respective regions.}

SPECIFICATION PARAMETER:

SELECTION CONDITIONS:

^{The volume of the tube side and shell side of the shell and tube heat exchanger is large. In order for the system to work properly, a large amount of medium must be filled. On the one hand, the semi-welded plate heat exchanger is small in size, and on the other hand, the spacing size is also small, so it occupies a small area, is easy to install, and saves space.}

^{Since water can form high-speed turbulence in the plate heat exchanger at a low flow rate, the temperature distribution is very uniform, thus reducing the freezing tendency of the chilled water. Even if freezing occurs, it can better withstand the pressure generated by freezing and can continue to be used after freezing, unlike shell and tube heat exchangers, which are prone to tube rupture.}

FAQ:

• ^{The sizing process involves considering factors such as the heat transfer rate required, the inlet and outlet temperatures of the fluids, the flow rates of the hot and cold fluids, the physical properties of the fluids (such as specific heat, density, and viscosity), and the allowable pressure drops. This is usually done using heat transfer calculations and engineering software or following industry-standard sizing methods.}

• ^{With proper maintenance and operation, a Plate And Shell Heat Exchanger can last 10 to 20 years or more, depending on the operating conditions and the quality of the materials used. However, factors such as corrosive fluids, high temperatures and pressures, and frequent start-stop cycles can affect its lifespan.}
