Combined type packing

Abstract

The invention relates to combined type packing, and belongs to the technical field of physical separation operation units. The combined type packing is formed by splicing and combining some bulk and stacked packing, wherein the bulk and stacked packing comprise a three-dimensional ring surface with openings in upper and lower ends and a plurality of interior extended tongue pieces; windows are further arranged on the three-dimensional ring surface; a connecting bridge is arranged in a middle position of the window; one end of each interior extended tongue piece is arranged on the connecting bridge; a card slot, which is as wide as the connecting bridge, is arranged between windows; a snap joint, by which the connecting bridge and the card slot are in card connection and are matched, is arranged at an outer opening of the card slot; and the interior extended tongue pieces are coated with oleophobic layers. The combined type packing is formed by splicing and combining some bulk and stacked packing; the overall passing ability of the combined type packing is improved by coating the splicing part and the interior part of the bulk and stacked packing; and the effect of a distributor can be achieved to certain extent by planning different funnel-shaped collectors, thereby improving the overall utilization rate of the combined type packing.

Description

technical field [0001] The invention relates to a combined packing, which belongs to the technical field of physical separation operation devices. Background technique [0002] Gas-liquid mass transfer equipment is essential in unit operations such as absorption, desorption, rectification, and extraction, which are widely used in the chemical industry and the petroleum industry. Tower equipment is one of the gas-liquid mass transfer equipment that makes gas-liquid into two phases and achieves the purpose of interphase mass transfer and heat transfer through precise contact. [0003] Tower equipment is generally divided into two categories: interstage contact type and continuous contact type. The representative of the former is a plate tower, and the representative of the latter is a packed tower. Among various tower types, the most widely used ones are sieve plate tower and valve tower. [0004] The packed tower is a mass transfer device in which the packing in the tower i...

AI Technical Summary

Problems solved by technology

Packed towers also have some disadvantages, such as high packing cost; when the liquid load is small, the surface of the packing cannot be effectively wetted, which reduces the mass transfer efficiency; it cannot be directly used for materials with suspended solids or easy polymerization; side feed and Complicated rectification such as discharge is not suitable, etc.
