Description
Technical Field
[0001] The utility model relates to the technical field of graphite heat exchange, in particular to a tubular graphite heat exchanger. Background Art
[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. Block hole type: It is assembled from several block-shaped graphite components with holes. Shell and tube type: Shell and tube heat exchangers occupy an important position in graphite heat exchangers. According to the structure, they are divided into fixed type and floating head type. Plate type: Plate heat exchangers are made of graphite plates. In addition, there are immersion type, spray type, and sleeve type. Graphite heat exchangers have good corrosion resistance, the heat transfer surface is not easy to scale, and the heat transfer performance is good. However, graphite is easy to crack, and has low bending and tensile strength, so it can only be used for low pressure. Even the block hole structure with the best pressure bearing capacity generally has a working pressure of only 0.3 to 0.5 MPa. Graphite heat exchangers are expensive, bulky, and rarely used. They are 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. With the development of society, graphite heat exchangers are used when temperature needs to be converted.
[0003] The inventors found in their daily work that when normal temperature water is input into a graphite heat exchanger and the graphite heat exchanger is started, the graphite heat exchanger converts the normal temperature water into high temperature water or low temperature water. However, after long-term use, scale will form on the inner wall of the water inlet of the graphite heat exchanger, resulting in a decrease in the water inlet of the graphite heat exchanger, which in turn leads to a decrease in the working efficiency of the graphite heat exchanger.
