Novel hexagonal inner arc ring packing

Abstract

The invention discloses novel hexagonal inner arc ring packing which comprises packing rings, wherein the packing rings are molded through once stamping; the packing rings are of a hexagonal structure as a whole; a window which is formed inwards and a sub-window in the middle of the window are formed between the middle parts of every two adjacent sides of the packing rings; an annular tongue is stamped inwards in a radial direction on the inner side of each window; a sub-tongue is stamped inwards in the radial direction on the inner side of each sub-window; and saw teeth are arranged at the lower ends of the sub-tongues. The whole packing rings of the novel hexagonal inner arc ring packing are of the hexagonal structure; in packing, linear contact of rings is effectively reduced, and thus the resistance of gases and liquids passing through a packing layer is reduced; and due to the saw teeth at the lower ends of the sub-tongues, the area of the packing is sufficiently utilized, and the packing can be distributed relatively sufficiently.

Description

technical field [0001] The invention belongs to the field of packing manufacture, and in particular relates to a novel hexagonal inner arc ring packing. Background technique [0002] In chemical engineering, fillers are often used to fill the tower to increase the contact surface of gas and liquid, so that they can be strongly mixed with each other. At present, most of the common metal fillers on the market are ring structures, and the ring walls are stamped inward to form a ring shape. The array of tongues, this structure improves the gas-liquid distribution and makes full use of the inner surface of the ring. Compared with the Raschig ring, the processing capacity can be increased by more than 50%, and it has the advantages of large flux, small resistance, and separation It has the advantages of high efficiency and large operating flexibility, but the metal packing rings in the market are mostly in linear contact with each other, and the holes between the rings are blocked...
