Abstract

The invention discloses a high-temperature-resistant corrosion-resistant graphitic acid distributor and a manufacturing method thereof. The graphitic acid distributor comprises an acid disc, wherein overflow pipes are uniformly distributed inside the acid disc; both the acid disc and the overflow pipes are made of graphite material. The acid distributor is made of the graphite material, the graphite has high-temperature resistance and corrosion resistance, the influence of temperature on the graphite material is slight, the deformation amount is small, the distribution uniformity of materials in tower equipment in chemical production is guaranteed, and bias of the materials in the tower equipment is reduced. Compared with the conventional acid distributor made of a polytetrafluoroethene material, the graphitic acid distributor manufactured by adopting the manufacturing method has the advantages that the temperature resistance and corrosion resistance are improved by 30 percent, the strength is improved by 5-10 times, the bias is reduced, the production consumption is lowered, the service life is prolonged by two times, the problem that the high-temperature highly corrosive materials are easily biased in the tower equipment is solved, and great contribution is made to the development of fluorine chemical industry and other petrochemical industries.

Description

technical field [0001] The invention relates to a method for manufacturing a high-temperature and corrosion-resistant graphite acid distributor, and belongs to the technical field of acid distributor manufacturing technology. Background technique [0002] In chemical production, the existing high-temperature-resistant and corrosion-resistant acid distributors are made of PTFE materials. Since PTFE materials are easily deformed at high temperatures, the uniform distribution of acid in the tower equipment cannot be guaranteed, so that the acid The distribution in the tower equipment produces bias flow, which leads to uneven absorption or separation of gas and liquid, which seriously affects the output and quality of chemical production. The uneven distribution of acid in the tower equipment will also cause damage to downstream equipment, which seriously restricts the equipment. production, resulting in serious economic losses. Contents of the invention [0003] The purpose ...
