Graphite heat exchanger for chemical industry is mainly used for heat exchange in chemical reaction process, with high temperature. Graphite is an ideal heat exchange material with high temperature resistance of 4000 ℃.
Manufacturer of graphite heat exchanger
Graphite heat exchanger can be divided into three types according to its structure: block hole type, tube shell type and plate type. It has good corrosion resistance, no scaling on the heat transfer surface, and good heat transfer performance. However, graphite is easy to crack, has low bending resistance and tensile strength, and is only suitable for low pressure applications. Even for the block hole structure with good pressure bearing performance, its working pressure is generally only 0.3~0. 5M pa.
It is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid, and as the condenser of acetic acid and acetic anhydride. Graphite condenser is mainly used in chlor alkali chemical industry, petrochemical industry, fluoride salt, titanium dioxide, zircon, chloroacetic acid, chlorinated paraffin, monocrystalline silicon and other industries.
