Material Selection of Water-Ring Vacuum Pump in Yellow Phosphorus Tail Gas Industry

Abstract:

Material selection of water-ring vacuum pumps in the chemical industry is closely related to the suction gas medium composition. Using the case of 70,000 tons of sodium yellow phosphorus tail gas system of water-ring vacuum pump in Guizhou Kaiyang Qingli tianmeng Chemical Ltd. (hereafter abbreviation as Tianmeng Company), this paper introduces vacuum pump in the production process of yellow phosphorus tail gas, according to the characteristics of corrosion in acidic media on flow passage component, and analyze the factors influencing the selection of materials from the point of view of the production process of yellow phosphorus tail gas.
