Background

The graphite heat exchanger can be divided into 3 types of block hole type, shell and tube type and plate type according to the structure. The block hole type graphite assembly is formed by assembling a plurality of block graphite assemblies with holes. The shell-and-tube type and shell-and-tube type heat exchanger has an important position in a graphite heat exchanger, and is divided into a fixed type and a floating head type according to the structure. The plate type/plate type heat exchanger is made by bonding graphite plates. Furthermore, submerged type, shower type, double pipe type and the like are also used (see a coil pipe type heat exchanger, a double pipe type heat exchanger). The graphite heat exchanger has good corrosion resistance, and the heat transfer surface is not easy to scale, so that the heat transfer performance is good. However, graphite brittle molding is not easy to crack, and therefore, the molding can only be used for low-pressure molding, even the block hole-shaped structure with the best pressure bearing capacity, and the working pressure of the molding is generally only 0.3 to 0.5 MPa. The graphite heat exchanger has high cost and large volume, and is not used much. The heat exchanger is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid, phosphoric acid and the like, and is used as a condenser for acetic acid and acetic anhydride and the like. Graphite pipes are classified into synthetic resin impregnation, water glass resin impregnation, and pitch impregnation according to the material to be impregnated. In the prior art, the heat exchanger has poor heat exchange effect of double flows except for single flow, so that resources are wasted, and great economic waste is caused to enterprises. Therefore, a circular hole type multi-flow graphite heat exchange device is provided.
