[structure and characteristics]
Liuleng brand impervious graphite packed tower is usually used for absorption, concentration, distillation, evaporation, filtration, washing and other chemical unit operations of hydrochloric acid, sulfuric acid and other corrosive properties. It is a process of heat and mass transfer when gas-liquid contact. In operation, the flow direction of gas and liquid is generally counter current. The liquid from the top of the tower is sprinkled uniformly by the spray device, and the gas rises from the bottom of the tower. The gas-liquid two-phase contact each other through the surface of the filler, so as to transfer heat and mass.
P : -0.1 ~ 0.5MPa
Specification: DN200 ~ DN3600
Packed tower is usually used for absorption, concentration, distillation, evaporation, filtration, washing and other chemical unit operations of corrosive media such as hydrochloric acid and sulfuric acid.[equipment advantages]
Graphite packed tower has the advantages of simple structure, convenient manufacture, small pressure drop and strong adaptability. It is directly used to treat corrosive materials with viscosity, easy foaming and low heat sensitivity, or the mass transfer rate is controlled by gas phase.
