Embodiment Construction

[0014] Combined with Figure 1, Figure 2, Figure 3, and Figure 4, a hollow cylinder with equal height and diameter is made by using polytetrafluoroethylene powder material through molding and post-processing. There are four tongues on the inner wall next to each layer of window holes, and each tongue is bent inward to point to the center of the column. The positions of the two layers of windows and tongues are opposite and staggered. New Pall ring.

[0015] With reference to Fig. 3, the manufacturing process flow of the present invention is: molding, sintering, stamping. The specific production process is as follows:

[0016] 1. Molding: the basic structure of the present invention is formed by molding. The whole mold combination is composed of three parts: outer jacket, inner jacket and mold core. First, use 2 mold cores, one right-handed and one left-handed, and the cross blades are connected together with screws, install the inner sleeve of the material, and then the outer...

Abstract

A Pall ring as the filler of tower is a hollow cylinder. Its height is equal to its diameter. Its wall has windows and more than 3 tongues on its inner surface and close to each layer of windows. Its preparing process includes providing Teflon powder, die pressing, sintering and punching.

Description

technical field [0001] The invention relates to a column filler used for vapor-liquid exchange in the chemical industry, in particular to a novel Pall ring and its manufacturing process. Background technique [0002] Packed column is one of the most commonly used gas-liquid mass transfer equipment, widely used in separation projects such as rectification, absorption, extraction, heat exchange, etc. Pall ring packing is a new type of packing developed internationally in the 1970s. It is mainly used as packing in chemical plants, pharmaceutical plants, and chemical towers in various water treatment systems. Due to the requirements of the manufacturing process, chemical gases and liquids are required to travel in sequence in the tower, and the more fully the exchange is required, the better, and the resistance in the tower is not allowed to be too high. Adding packing in the empty tower is to make the chemical gas flow and The liquid flow is fully contacted to achieve the purp...
