[0002] Graphite heat exchanger is a heat exchanger made of graphite for heat transfer components. The graphite used to make heat exchangers should be impermeable. Impregnated impermeable graphite and pressed impermeable graphite are commonly used. Graphite heat exchangers can be divided into three types according to their structure: block hole type, shell and tube type, and plate type. Graphite heat exchangers have good corrosion resistance, and the heat transfer surface is not easy to scale. The heat transfer performance is good. It is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid, such as condensers for acetic acid and acetic anhydride, etc. It is mainly used in chlor-alkali chemical industry, petrochemical industry, fluoride salt, titanium dioxide, zirconium industry, chloroacetic acid, chlorinated paraffin, single crystal silicon fluorine chemical industry and other production industries.

[0003] The installation connection point between the crane and the graphite heat exchanger body is not stable enough, and the manual binding method of the lifting rope and the graphite heat exchanger body is not tight enough, resulting in low efficiency in the installation and connection of the graphite heat exchanger body. Therefore, it is necessary to design a graphite heat exchanger body that is easy to connect to solve the above problems. Utility Model Content
