Abstract

The invention relates to the field of chemical industry, in particular to a silicon carbide heat exchanger tube plate and a silicon carbide heat exchanger. The silicon carbide heat exchanger tube plate and the silicon carbide heat exchanger have the beneficial effects that the silicon carbide heat exchanger tube plate comprises a tube plate body and metal reinforcing pieces, wherein the tube platebody is made of a non-metal material, a plurality of tube holes used for containing silicon carbide tubes are formed in the tube plate body, and the tube holes are arranged at intervals; the metal reinforcing pieces are arranged inside the tube plate body, and the metal reinforcing pieces are arranged between every two adjacent tube holes correspondingly; the metal reinforcing pieces are arrangedinside the tube plate body which is made of the non-metal material, so that the mechanical strength of a polytetrafluoroethylene material tube plate under a high-temperature and high-pressure workingcondition is effectively improved, and the use pressure and the use temperature of the whole silicon carbide heat exchanger tube plate are improved; and the problems that adverse effects are generated on the silicon carbide tubes due to the fact that an existing four-fluorine tube plate is prone to deform and creep at high temperature are solved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a silicon carbide heat exchanger tube sheet and a silicon carbide heat exchanger. Background technique [0002] Silicon carbide has extremely high corrosion resistance, oxidation resistance and erosion resistance, and can withstand high concentrations of sulfuric acid, nitric acid, phosphoric acid, mixed acids, strong alkalis, oxidants, etc. It is the only ceramic material that can resist hydrofluoric acid corrosion. [0003] As a new type of material, silicon carbide heat exchangers have not been widely promoted in the manufacture of chemical equipment. The main reason is that the manufacturing technology of silicon carbide heat exchangers is not mature enough. In particular, there are still defects in the selection and processing of heat exchanger tube sheets. The application of silicon carbide heat exchangers under higher temperature and pressure conditions. [0004] Existing...
