Graphite heat exchanger is a kind of heat exchanger made of graphite which is often used in industry. High quality sulfuric acid diluters can be divided into three types according to their structures. One is shell and tube graphite heat exchanger. This kind of heat exchanger is quite important. If subdivided according to the structure, it can be divided into fixed type and floating head type. It is a kind of inter wall heat exchanger with simple structure and easy operation. With metal as the main material, it can use various structural materials and can be operated under ultra-high temperature and pressure. It is widely used. The other is plate graphite heat exchanger. That is, it is bonded with graphite plate.
The utility model belongs to a new and efficient heat exchange equipment, which uses some metal sheets with corrugated shapes to stack, and the heat can be exchanged between each sheet.
Plate graphite heat exchanger is often used for heat exchange between liquid and liquid, and between liquid and gas. It must have high heat exchange efficiency, less heat loss, rather compact structure, and does not occupy too much space. It is very easy to clean and install, and has a wide range of applications. It takes a long time to use. Under the same conditions, the heat transfer coefficient of plate graphite heat exchanger is three to five times higher than that of other tube type heat exchanger, while the space used is only one third of that of tube type, and the heat recovery can reach more than 90%. Another commonly used heat exchanger is block hole graphite heat exchanger, which is composed of many elements with holes. In addition, there are casing type, coil type and so on.
