The working principle of graphite heat exchanger is introduced in detail？

As a good heat exchanger, graphite heat exchanger is widely used in many fields. When we buy graphite heat exchangers, we must have a good understanding of some structural principles of graphite heat exchangers to ensure the use of graphite heat exchangers. Today, Xin Boao will introduce some structure and working principle of graphite heat exchanger for your reference.

Graphite heat exchangers can be divided into three types according to their structure: block type, shell and tube type and plate type. Block hole type: Consists of multiple block hole graphite components. Shell and tube heat exchangers play an important role in graphite heat exchangers. According to their structure, they can be divided into fixed and floating heads. The plate heat exchanger is made of graphite plates bonded together. In addition, there are submerged, spray and double-pipe type (see coil heat exchanger and double-pipe heat exchanger). Graphite heat exchanger has the characteristics of good corrosion resistance, heat transfer surface not easy to scale, and good heat transfer performance. However, graphite is fragile, has low bending and tensile strength, and can only be used under low pressure. Even with a block-hole structure with strong bearing capacity, its working pressure is generally only 0.3 ~ 0.5 MPa. Graphite heat exchangers are relatively expensive, bulky, and have fewer applications. This product is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid, phosphoric acid, and used as a condenser for acetic acid and acetic anhydride.

It not only has acid resistance and corrosion resistance, but also has good heat transfer performance. The graphite core forms a vertically and horizontally separated block hole structure, so that the high-temperature medium continuously transfers heat between the two media, and the low-temperature medium continuously obtains heat from the heat exchanger between the two media, thereby realizing heat exchange. The utility model relates to a graphite heat exchanger for heat transfer elements. The graphite used in the production of heat exchangers should be impermeable materials, and impregnated impermeable materials and pressed impermeable materials are commonly used. Graphite heat exchangers can be divided into three types according to their structure: block type, shell and tube type and plate type. Combined type: a combined type composed of several graphite blocks with holes. Tubular type: Tubular heat exchanger is an important part of graphite heat exchanger, which can be divided into fixed type and floating head type according to the structure. Plate type: The plate heat exchanger is composed of graphite plates.
