Analysis of chemical heat exchanger application prospect

Are made of metal material heat exchanger general change, including carbon and low alloy steels are mostly used for manufacturing, low pressure heat exchanger; stainless steel is mainly used for the corrosion conditions except different resistance, austenitic stainless steel can also be used as a high, low temperature materials; copper, aluminum and its alloy used for the manufacture of low temperature heat exchanger; nickel alloy used in high temperature conditions; non metallic materials in addition to make gasket parts, some have begun for the production of corrosion resistant non-metallic materials such as graphite heat exchanger, heat exchanger, fluorine plastic heat exchanger and glass heat exchanger.
Heat exchanger is one of the widely used in chemical, petroleum, unit energy and other industry. According to statistics, the heat exchanger in the modern chemical industry investment accounted for about 30% of the total investment of equipment, accounting for about all the process equipment in refinery process units 40%, desalination is almost entirely composed of heat exchanger. The investigation shows that the heat exchanger market abroad, although a variety of plate heat exchanger's competitiveness on the rise, but the shell and tube heat exchanger is still dominant in about 64%.
The results model heat transfer element and the research and development of heat exchanger of high efficiency heat exchange shows that the shell and tube heat exchanger has entered a new period of time, both the heat transfer pipe, or shell baffle structure than the conventional shell and tube heat exchanger has been greatly changed, the fluid the mechanical properties, thermal efficiency, anti vibration and anti scaling effect from theory research to the structure design also has made new progress.
In recent years, with the research on the technology of high temperature heat pipe to mature and deep, high temperature heat pipe heat exchanger application fields expand gradually, has been widely used in various industrial, civil and national defense fields. In the metallurgical, chemical, ceramics, building materials, light industry and other industrial production, often need to clean the air above 500 degrees in order to meet the need of oxygen combustion, drying and etc, using high temperature heat pipe air heater can easily achieve this one requirement, and solve the heat transfer problem of the conventional air heater which can't be solved fundamentally.
