Plate heat exchanger
This equipment is a highly efficient heat transfer equipment for gas - gas, liquid - liquid, gas - liquid convection heat transfer, as well as for steam condensation and liquid evaporation. The product has a high heat transfer efficiency, self-cleaning ability dirt, energy saving, small and inexpensive to use and reliable. Is widely used in pharmaceuticals, solvents, chemicals, rosin, dyes, food industry, heat exchange, waste heat recovery.
Plate heat exchanger design features: 一、High efficiency heat exchanger Heat transfer coefficient usually ranging from2000—5000kcal/m2hr℃ ,Shell and tube heat exchanger than the 3-5 times higher。 二、Compact Film due to heat transfer in close order, and other forms of heat exchanger compared to a smaller area or space,。 三、Easy maintenance Plate tightly assembled together, ready to open the maintenance and cleaning。 四、Life long Plate can be used 0.6-1.0 mm 304.316.316L stainless steel or titanium alloy sheet made repression can be a variety of corrosion-resistant media. 5, assembly and flexible solution without strings heat transfer area may be different according to the user requirements of assembled machine, such as the initial power to change through changes in the plate can be. In addition, because access is a two-plate sealed, grain vent steam flow Daoxing into what may be the security zone, thus avoiding the possibility of two kinds of media collusion. "

Caution: STRONG> one, first check the pre-boot the entire pipe connection system as well as the fluid required by the form of import and export links, open the boot due to the first low-temperature low-pressure valve , and then open the high-temperature high-pressure fluid valves. Shutdown to close the high-temperature high-pressure fluid valves, and then close the low-temperature low-pressure fluid valves. 2, plate heat exchangers used in liquid - liquid exchange, do not need to set up exhaust devices, steam - gas exchange and low-velocity high-viscosity fluids should be set up in the piping system exhaust valves, lose steam trap improve the efficiency of heat transfer units. 3, plate heat exchangers over a long period of continuous operation, due to fluid accumulation in the sediment sets the surface of the plate, increasing the thermal resistance, so that reduces heat transfer efficiency, maintenance staff carry out regular cleaning and maintenance. 4, maintenance time, such as the need to replace gaskets, first plate with acetone or ethyl acetate cleaned, and then each slot in the plate and sealing mat coated with adhesives, which will be a little dry gasket embedded, such as tank, surrounded by uniform pressure level, a few hours can be assembled.
