Description

Technical Field

[0002] Graphite heat exchanger is a heat exchanger whose heat transfer components are made of graphite. The graphite used to make the heat exchanger should be impermeable. Impregnated impermeable graphite and pressed impermeable graphite are commonly used. 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 crack and has low bending and tensile strength. Therefore, it can only be used for low pressure. Even the block pore structure with the best pressure bearing capacity is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid.

[0003] For example, publication number CN205909713U, the utility model relates to a round block hole type graphite heat exchanger, which includes a steel shell and a graphite lining, and a gap is provided between the steel shell and the graphite lining to form a heat exchange flow channel; its innovation lies in: the heat exchanger includes an upper cover plate, an upper head, a distributor, a heat exchange layer, a lower head and a lower cover plate arranged from top to bottom; the graphite tube mounting holes arranged on the graphite plate of the distributor are evenly distributed on the graphite plate in a honeycomb shape with equal spacing, which is beneficial to the uniform distribution of the high-temperature liquid after passing through the distributor to facilitate heat exchange; by adopting a plurality of heat exchange holes arranged on the heat exchange block, the heat exchange flow channel formed between the steel shell and the graphite lining is connected to the heat exchange holes on the heat exchange block, thereby reducing the interval between the heat exchange medium flow channel and the high-temperature acid liquid channel, and improving the heat exchange effect.

[0004] After long-term use, the existing round block hole type graphite heat exchanger may cause the impurities and dust contained in the heat conducting medium to accumulate and condense into scale inside the graphite pores due to the high working environment temperature of the heat conducting medium, thereby affecting the heat exchange efficiency of the round block hole type graphite heat exchanger.
