Description

High-efficient shock attenuation graphite heat exchanger

Technical Field

The invention is applied to the industrial field, and particularly relates to a high-efficiency damping graphite heat exchanger.

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, the graphite molding device is brittle and has low bending and tensile strength, so that the molding device can only be used for low pressure molding devices, even the block hole-shaped structure with the best pressure bearing capacity, and the working pressure of the molding device is generally only 0.3-0.5 MPa. The graphite heat exchanger has high cost and large volume, and is not used much. The graphite heat exchanger is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid, phosphoric acid and the like, such as a condenser used for acetic acid and acetic anhydride and the like, the graphite heat exchanger has good corrosion resistance, a heat transfer surface is not easy to scale, the heat transfer performance is good, but graphite is easy to crack and has low bending resistance and tensile strength, so that the graphite heat exchanger can only be used for low pressure.
