Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a graphene tube-in-tube heat exchanger. Background Art

[0002] Graphite tube heat exchanger exchanges heat through graphite heat exchange tubes in the heat exchanger shell. Generally, tube sheets are provided at both ends of the graphite heat exchange tubes to support the graphite heat exchange tubes. The graphite used to manufacture the heat exchanger should be impermeable. Impregnated impermeable graphite and pressed impermeable graphite are commonly used. Graphite materials are corrosion-resistant non-metallic materials.

[0003] In the prior art, heat exchange is performed directly without preheating the outer shell and heat exchange tubes. Failure to preheat the outer shell and heat exchange tubes means that when the equipment is started, the system will take longer to reach the operating temperature, which will reduce the efficiency of the heat exchanger and lead to higher energy consumption, resulting in energy waste. When the equipment is started, if there is no preheating, there is a risk of water vapor condensing in the pipes or equipment, which may cause pipe corrosion, rust blockage or other adverse effects, thereby affecting the reliability and performance of the system. Lack of preheating may cause the equipment to experience more frequent temperature changes, which may accelerate material fatigue and aging. Frequent thermal expansion and contraction may cause damage to equipment parts and shorten the life of the equipment. Utility Model Content
