Abstract
The invention discloses a ripple filling material with multiple layers of gas/liquid runners. The filling material is novel structured packing used in a packed tower. The filling material is composed of a plurality of filling blocks. Each filling block is prepared by laminating multiple ripple plate units. Each ripple plate unit is prepared by pressing a thin steel plate, a plate-flower net, a silk screen, and a non-metal belt together, and comprises two external ripple plates and one internal ripple plate. The internal ripple plate is arranged in the middle part of the ripple plate unit, and two external ripple plates are arranged on two sides of the middle part of the ripple plate unit. The gas/liquid runners of the external ripple plates and internal ripple plate are parallel to each other. The ripple filling material has the advantages of large flux, small resistance, high efficiency, and strong obstruction resistant performance, and can be used in the fields such as chemical engineering, oil refining, petrochemical industry, ethylene industry, pharmacy, natural gas industry, and the like.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that described herein
Specific embodiment only in order to explain the present invention, is not intended to limit the present invention.
Provided by the invention by a kind of ripple packing with multilayer gas-liquid runner, its profile can be square type, cuboid, cylinder etc., and the present embodiment is described in detail to ripple packing with cylindrical structure.
As shown in Figure 4, the ripple packing with multilayer gas-liquid runner is made up of multiple filling block 1, and is fixed by the strap 2 around filling block 1.
As shown in Figure 3, filling block 1 is superposed by multiple corrugated cardboard sheet unit 3 and forms the cross-sectional structure of filling block 1.
As shown in Figure 5, if the gas-liquid runner direction of two corrugated cardboard sheet unit 3 is respectively X-axis and Y-axis, then X-axis and Y-axis, the angle of the axis of X-axis and packed tower is 40 °, the angle of the axis of Y and packed tower is 40 °, and the angle between X-axis and Y-axis is 80 ° and with the axis of packed tower for axle becomes axial symmetry.
As depicted in figs. 1 and 2, corrugated cardboard sheet unit 3 comprises the interior corrugated cardboard sheet 4 be arranged in the middle part of corrugated cardboard sheet unit 3 and the outer corrugated cardboard sheet 5 being arranged on corrugated cardboard sheet unit both sides.
The vertical cross-section in interior corrugated cardboard sheet 4 runner direction is continuous V-shaped and connects at V-shaped summit place.
The vertical cross-section in outer corrugated cardboard sheet 5 runner direction is continuous V-shaped and connects at V-shaped summit place, described outer corrugated cardboard sheet comprises upper outside corrugated cardboard sheet 5a and lower outside corrugated cardboard sheet 5b, upper outside corrugated cardboard sheet 5a is arranged on the top of corrugated cardboard sheet unit 3 and the V-shaped summit 6 of upper outside corrugated cardboard sheet 5a overlaps with the V-shaped summit place of interior corrugated cardboard sheet 4, and lower outside corrugated cardboard sheet 5b is arranged on the bottom of corrugated cardboard sheet unit 3 and the V-shaped peak base 7 of lower outside corrugated cardboard sheet 5b overlaps with the V-shaped peak base place of interior corrugated cardboard sheet 4.
The V-shaped angle a of outer corrugated cardboard sheet 5 is 100 °-160 °, is 120 ° in the present embodiment, and the V-shaped angle of interior corrugated cardboard sheet 4 is 60 °-100 °, is 85 ° in the present embodiment, and the angle of angle a is greater than the angle at angle.
The interior corrugated cardboard sheet 4 of same corrugated cardboard sheet unit 3 and the gas-liquid runner of outer corrugated cardboard sheet 5 are parallel to each other, and the peak separation between gas-liquid runner is equal.
