Embodiment 1

[0013] Example 1, the light-weight reinforced porcelain corrugated structured packing is in the shape of a patchwork with a maximum diameter of 650mm, which is formed by superimposing six unit plates with corrugated cross-sections. The light-weight reinforced porcelain corrugated regular packing The filler is mainly composed of 10% by weight of high-quality aluminum powder, 70% by weight of high-silica clay, 5% by weight of quartz and 15% by weight of feldspar. The mud is extruded into a billet in a mold, and the billet is kept at 200-300 °C for 2 hours, dehydrated and dried, and then calcined and refined at 900-1000 °C for 4 hours.

Embodiment 2

[0018] Example 2, the light-weight reinforced porcelain corrugated structured packing is in the shape of a whole disk, with a maximum diameter of 420 mm, which is formed by superimposing four unit plates with corrugated cross-sections. The filler is mainly composed of 22% by weight of high-quality aluminum powder, 55% by weight of high-silica clay, 10% by weight of quartz and 13% by weight of feldspar. The mud is extruded into a billet in a mold, and the billet is kept at 200-300 °C for 2 hours, dehydrated and dried, and then calcined and refined at 900-1000 °C for 4 hours. The diameter of the packing is 3-5 mm smaller than the inner diameter of the tower, and the gap between the packing and the tower wall can be filled with glass fiber, asbestos or polyethylene tape to prevent wall flow and wear between the packing and the tower wall.

[0023] Example 3, the light-weight reinforced porcelain corrugated structured packing is a piece-shaped packing with a maximum diameter of 420 mm, which is formed by superimposing 10 unit plates with corrugated cross-sections. The filler is mainly composed of 30% high-quality aluminum powder, 45% high-silica clay, 15% quartz and 10% feldspar, which is uniformly mixed. After drying and screening, it is ball-milled into thick porcelain mud, which is extruded into a mold to form a billet. After dehydration and drying at 200-300°C for 2 hours, it is calcined and refined at 900-1000°C for 4 hours.

Abstract

The invention discloses a light strengthen porcelain corrugated structured stuff, which is composed of laminated light porcelain stuff units with corrugated shapes, wherein the units are dried, selected and ball ground into petuntse, to be shaped into blank, dewatered, dried, calcined and refined. The light strengthen porcelain corrugated structured stuff unit contains 10-30% of high quality aluminum powder, 40-70% of high silicon clay, 5-15% of quartz and 10-15% of feldspar. The inventive light strengthen porcelain corrugated structured stuff has thin wall, low weight, simple application, high application efficiency, low pressure decrease, high processing capacity, low liquid hold up, no obvisou amplification and high operation flexibility, which is not easy to break and is easy to assemble. Compared with prior corrugated stuff, the strength of the invention is improved of at least 30% and the corrosion resistance is improved of at least 20%, to meet the technical demands of oil refining.

Description

technical field [0001] The invention relates to a light-weight ceramic packing, in particular to a light-weight reinforced ceramic corrugated structured packing. Background technique [0002] The existing ceramic corrugated plate structured packing has been developed by Sulzer of Switzerland since the 1970s. Because the ceramic corrugated plate packing has high dispersion efficiency, small pressure drop, and relatively high processing capacity and liquid holding capacity. It has been widely used in chemical, petroleum and fine chemical industries due to its advantages of large size and insignificant amplification effect. At present, most of this kind of ceramic corrugated plate structured packing is light ceramic corrugated structured packing, which is a cylindrical corrugated plate packing composed of many lightweight ceramic packing units with the same geometric shape. However, with the increasing sulfur content and acid value in petroleum, and the production of high-temp...
