Abstract

The invention relates to a silicon carbide graphite tube heat exchanger, which comprises a jacket, including an upper head, a middle sleeve and a lower head which are sequentially connected from top to bottom; Lining, including the upper tube sheet arranged between the upper head and the middle sleeve, the lower tube sheet between the lower head and the middle sleeve, and the silicon carbide heat exchanger arranged in parallel between the upper tube sheet and the lower tube sheet Tubes, and the silicon carbide heat exchange tubes are connected with the upper tube sheet and the lower tube sheet with static seals. The advantages of the present invention are: by using silicon carbide heat exchange tubes, the heat exchange tubes have good high temperature resistance, high thermal conductivity, small thermal expansion coefficient, and good wear resistance by utilizing the characteristics of silicon carbide with stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance. High pressure resistance, suitable for heat exchange in high temperature and high pressure media.

Description

Technical field [0001] The invention relates to a heat exchanger, in particular to a silicon carbide graphite tube heat exchanger. Background technique [0002] Graphite heat exchanger has excellent corrosion resistance and heat transfer performance. It can be used in the heat transfer process of corrosive media and can give full play to the superiority of graphite equipment. In order to save stainless steel and precious non-ferrous metal materials, graphite heat exchangers are widely used to treat corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid. [0003] The tubular graphite heat exchanger has a simple structure, high utilization rate of graphite material, and can be made into a device with a larger heat transfer area, and the cost per unit heat transfer area is lower than other structural forms. [0004] For example, in the patent CN104180688A, a tubular graphite heat exchanger is mentioned. The inner graphite cylinder is formed by connect...
