Filler assembly capable of eliminating amplification effect

Abstract

The invention discloses a filler assembly capable of eliminating amplification effect, which comprises a filler section, a filler clapboard, filler units, a filler support plate and a liquid redistribution board, wherein the filler clapboard partitions the filler section into a plurality of filler units, the liquid redistribution board is provided with open pores matched with the filler units, a weir is arranged around the open pores, the weir is provided with tooth gaps, and the open pores have the shapes similar to those of the filler units, and have small area. The assembly changes a filler tower into the plurality of filler units connected in parallel, and the vapor and liquid of the filler section are uniformly distributed and the wall flow effect is eliminated by matching the corresponding liquid redistribution board so as to ensure efficient and stable mass transfer effect and eliminate the amplification effect; the adverse initial distribution of a liquid distributor is corrected; by adopting a plug-in structure, the treatment capacity of the tower is only related to the number of the filler units, so the design of the tower is not limited by the scale; and the liquid distributor is replaced by a distribution board so as to reduce the requirements on tower height and mounting level and reduce the investment.

Description

Technical field [0001] The invention relates to a packing assembly mainly used in the petroleum and chemical processing industries and a packed tower including the assembly. Background technique [0002] Packed tower is a common separation tower equipment in oil refining and chemical production. Compared with the plate tower, the packed tower has obvious characteristics such as large specific surface area, high mass transfer efficiency, pressure drop, and corrosion resistance. The phase boundary area of ​​the packed tower for mass transfer is the surface where the packing is wetted by the liquid. The liquid enters the packed bed after being dispersed by the distributor and transfers the mass with the rising vapor phase. Unlike the plate tower, the vapor phase must pass through the tower. After the plate, it is dispersed into bubbles under the action of the resistance of the plate, and converted into the surface energy of the phase interface by consuming the pressure drop of the ...
