Block hole graphite heat exchanger can be divided into block hole type, tube shell type and plate type according to its structure. Block hole type: It is assembled by several block graphite components with holes. Shell and tube type: shell and tube heat exchanger plays an important role in graphite heat exchanger, which can be divided into fixed type and floating head type according to structure. Plate: plate heat exchanger is made of graphite plate. In addition, there are immersion type, spray type and casing type (see coil type heat exchanger, casing type heat exchanger). Graphite heat exchanger has good corrosion resistance, heat transfer surface is not easy to scale, and heat transfer performance is good. However, graphite is easy to embrittlement and has low bending and tensile strength, so it can only be used for low pressure. Even if the pressure bearing capacity is block porous structure, its working pressure is generally only 0.3~0.5 MPa. Graphite heat exchanger has high cost, large volume and little use. It is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid, such as condenser of acetic acid and acetic anhydride.

Graphite heat exchanger has high cost, large volume and little use. It is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid, such as condenser of acetic acid and acetic anhydride. It is mainly used in chlor alkali chemical industry, petrochemical industry, fluoride salt, titanium dioxide, zirconium industry, chloroacetic acid, chlorinated paraffin, monocrystalline silicon fluoride chemical industry and other production industries.
