Abstract

The utility model relates to fillers for the field of petrochemical engineering and particularly relates to spiral porous filler extracted from styrene. The spiral porous filler is composed of hexagonal ring bodies and rib sheets, wherein inner opposite angle vertexes of a hexagonal ring body I are respectively connected with the two ends of the S-shaped rib sheets; the three S-shaped rib sheets are crossed at the center of the hexagonal ring body I; the hexagonal ring body I is internally provided with a hexagonal ring body II and a hexagonal ring body III; all edges of the hexagonal ring body II and the hexagonal ring body III are fixedly arranged on the S-shaped rib sheets; the height-diameter ratio of the filler is 0.15-0.25. The spiral porous filler extracted from the styrene is excellent in mass transfer performance, good in permeability, small in resistance drop and low in bulk specific gravity; outwards-bent tongue pieces are alternated up and down and are propelled inwards, so that the porosity and the strength of the rings are improved; the manufacturing cost is low; the spiral porous filler extracted from the styrene is suitable for a styrene extraction process in the field of the petrochemical engineering.

Description

The spiral porous aggregate of styrene extracting

Technical field

The utility model relates to a kind of petrochemical industry filler, relates in particular to a kind of spiral porous aggregate of styrene extracting.

Background technology

Filler general reference is filled in the material in other objects, and in petrochemical industry, filler refers to be loaded on the inert solid material in packed column, as Raschig ring, Pall ring etc.Packed tower is mainly used in two between solution-air, liquid-liquid and contacts to realize quality transmission or chemical reaction, selects suitable filling kind, has directly determined the quality of packed tower performance.And due to the difference of process conditions, the structure of selected filler is also different.The filler using in existing styrene extraction process, due to its unreasonable structure, ratio of height to diameter is large, mass-transfer performance is poor, resistance drop is large, has increased production cost.

Summary of the invention

The utility model, for the styrene extraction process of petrochemical industry, provides a kind of spiral porous aggregate of styrene extracting.

The spiral porous aggregate of styrene extracting of the present utility model, to be formed by hexagon ring body and muscle sheet, the two ends that connected respectively S shape muscle sheet on the inner opposite angle summit of hexagon ring body I, three S shape muscle sheets meet at hexagon ring body Ⅰ center, be provided with hexagon ring body II and hexagon ring body III in the inside of hexagon ring body I, each limit of described hexagon ring body II and hexagon ring body III is all fixed on S shape muscle sheet; The ratio of height to diameter of this filler is 0.15～0.25.

As further improvement of the utility model, on each facade of described hexagon ring body I, hexagon ring body II and hexagon ring body III, have two bandy tongue pieces, on each facade, two bandy tongue piece opening directions are contrary.

As further improvement of the utility model, described tongue piece be shaped as triangle, rectangle or trapezoidal.

As further improvement of the utility model, the internal diameter of described hexagon ring body I is greater than the internal diameter of hexagon ring body II, and the internal diameter that internal diameter is greater than hexagon ring body II is greater than the internal diameter of hexagon ring body III.

As further improvement of the utility model, each seamed edge of described hexagon ring body II is positioned at 1/4th places at corresponding S shape muscle sheet two ends.

As further improvement of the utility model, each seamed edge of described hexagon ring body III is positioned at 3/8ths places at corresponding S shape muscle sheet two ends.

The spiral porous aggregate of styrene extracting of the present utility model, reasonable in design, mass-transfer performance is good, transparent performance good, resistance drop is little, contact is abundant, body proportion is low, its excurvation tongue piece is alternately upper and lower, and inwardly push away, and then improved the intensity of its voidage and ring, and cost of manufacture is low, is applicable to the styrene extraction process of petrochemical industry.
