Information

A fixed plate heat exchanger, also known as a heat exchanger, is a device that transfers part of the heat of the hot fluid to the cold fluid. It can transfer heat between materials at different temperatures. The fixed plate heat exchanger is a general-purpose equipment for many industrial sectors such as chemical, petroleum, electric power, and food. It is one of the main devices for improving energy efficiency. In chemical production, fixed plate heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and occupies an important position in production.

fixed plate heat exchanger
A fixed plate heat exchanger is a device that transfers heat from a hot fluid to a cold fluid, also known as a heat exchanger. Its main function is to guarantee the specific temperature required by the process to the medium. It can transfer heat between two or more fluids at different temperatures, so that heat is transferred from the high temperature fluid to the low temperature fluid, so that the temperature of the fluid can meet the requirements of the process conditions, and the fixed plate heat exchanger is the main one of the devices. Improve energy efficiency.
1. Plate type selection
The gasket type or corrugated type of the fixed plate heat exchanger should be determined according to the actual needs of the heat exchange occasion. In the case of large flow and small allowable pressure drop, the plate type with low resistance should be selected, otherwise, the plate type with large resistance should be selected. Depending on the fluid pressure and temperature, determine whether to choose a detachable type or a brazed type. When determining the plate type, it is not suitable to choose a gasket with too small a single plate area, so as to avoid too many gaskets, a small flow rate between the plates, and a low heat transfer coefficient. This problem should be paid more attention to for larger heat exchangers.
2. Pressure drop check
In the design and selection of the fixed plate heat exchanger, there are generally certain requirements for the pressure drop, so it should be checked. If the check pressure drop exceeds the allowable pressure drop, it is necessary to re-calculate the design and selection until the process requirements are met. Yuanwang BR type plate heat exchanger has the characteristics of high heat exchange efficiency, small material flow resistance loss, compact structure, sensitive temperature control, large operation flexibility, convenient assembly and disassembly, and long service life. It is the most advanced high-efficiency energy-saving in China. heat exchange equipment.
