Description

Efficient joint-cutting board corrugated filler

Technical Field

The utility model relates to a high-efficient joint-cutting board ripple packs belongs to the technical field that packs.

Background

The structured packing is widely applied to mass transfer separation processes such as rectification, absorption and the like in the fields of chemical industry, petroleum, light industry, medicine, environmental protection and the like. Since the advent of packed columns, the packing has developed rapidly due to its extremely high column efficiency, but the number of theoretical plates per meter of packing height has not been increased due to uneven distribution of fluid, wall flow effects, and radial irregular flow of fluid. The existing method is to reduce the radial flow and wall flow effect of fluid and improve the processing capacity and separation efficiency of the tower by folding the two ends of the chute on the traditional regular tower packing corrugated plate to form an S-shaped gas-liquid channel. Although the performance of the structured packing is improved to a certain extent, the packing has insufficient disturbance to the fluid, and the efficiency of gas-liquid mass transfer cannot meet the requirement of large-scale application, and needs to be further improved.
