Description

Arrow tail feather filler

The utility model relates to the used structured packing in a kind of chemical separating field.

The common filler that is used for the chemical separating field has random packing and structured packing two big classes, and structured packing is the filler of filler unit rule proper alignment.The structured packing that is most widely used at present is a ripple packing, its each cycle ripple is made up of two continuous levels, be processed with aperture, less ripple, reticulate pattern, decorative pattern or pit etc. on the plane, the oblique profile figure that dissects this filler gained perpendicular to the intersection on two planes is a triangle corrugated broken line.The liquid-phase flow path of regular corrugation filler is limited by ripple, and gas phase flows in the space of ripple, on the one hand, because the inclination angle of ripple causes partially liq to flow to the tower wall, forms wall stream; On the other hand, gas phase is subjected to the restriction of corrugated plating face, can not fully mix, and this has just caused filler to exist efficient not give full play to, and more high weak point falls in pressure.

The purpose of this utility model is to provide a kind of novel structured packing one arrow tail feather filler, improves the flow condition of liquid and gas by its unique filling-material structure shape, reduces flow resistance, reduces wall stream, makes it have better serviceability.

In order to achieve the above object, the utility model is realized by following proposal: the thin slice or the silk screen that adopt metal or non-metallic material, through being processed into the utility model one arrow tail feather filler, it is characterized in that, the herringbone unit that is processed with period profile on each packing sheet and is parallel to each other is arranged, and adjacent herringbone unit is arranged and intersected the sideline; Each herringbone unit is formed front principal plane, back interarea and adjacent quadrangle square hole of two muscle sheets formation by two interareas that are parallel to each other (front principal plane and back interarea) and period profile and the muscle sheet that is connected forward and backward interarea; Muscle sheet and front principal plane intersect preceding folding line, or are bent into arc surface; The muscle sheet intersects the back folding line with the back interarea, or is bent into arc surface; Before the angle α in folding line or back folding line and crossing sideline be 0～90 °, muscle sheet sideline on interarea forward projection and the angle β in crossing sideline be 10～90 °, the dihedral of muscle sheet and the formation of forward and backward interarea is 100～180 °; Muscle sheet interlaced arrangement during adjacent herringbone unit is arranged, the dihedral angle φ that the adjacent interarea of adjacent herringbone unit forms is 10～180 °; Two adjacent herringbone units can be that front principal plane and front principal plane join, and also can be that the back interarea joins with the back interarea, can also be that front principal plane joins with the back interarea.The feature of above-mentioned arrow tail feather filler also is, the interarea that constitutes herringbone unit can be a continuous level, it is shaped as a concave polygon, it also can be interrupted plane, be shaped as the quadrangle or the recessed pentagon of period profile, can also be arc surface, and can allow front principal plane identical or different with the shape of back interarea; The muscle plate shape that constitutes herringbone unit can be quadrangle or triangle, can be the plane, also can be arc surface, can also form single arc surface jointly with interarea; The angle β of adjacent herringbone unit can be identical, also can be different; On the interarea of herringbone unit and muscle sheet, ripplet, reticulate pattern, decorative pattern or pit can be processed with, also some apertures or acanthopore can be processed with.

Below in conjunction with accompanying drawing the utility model is described in detail.

The herringbone unit [1] that is processed with period profile on each packing sheet of arrow tail feather filler and is parallel to each other is arranged.Adjacent herringbone unit [1] is arranged and is intersected sideline [2].Each herringbone unit is made up of two interareas that are parallel to each other (front principal plane [3] and back interarea [4]) and period profile and the muscle sheet [5] that is connected forward and backward interarea, front principal plane [3], back interarea [4] and adjacent two muscle sheets [5] form a quadrangle square hole [8], muscle sheet [5] intersects preceding folding line [6] with front principal plane [3], or is bent into arc surface; Muscle sheet [5] intersects back folding line [7] with back interarea [4], or is bent into arc surface.As Fig. 1～shown in Figure 6.Preceding folding line [6] or back folding line [7] are 0～90 ° with the angle α in crossing sideline [2], the forward projection [9] of muscle sheet sideline on interarea and the angle β in crossing sideline [2] are 10～90 °, and muscle sheet [5] is 100～180 ° with the dihedral that front principal plane [3], back interarea [4] form.Muscle sheet [5] interlaced arrangement during adjacent herringbone unit [1] is arranged.The dihedral angle φ that the adjacent interarea [3] of adjacent herringbone unit [1], [4] form is 10～180 °.Adjacent two herringbone units [1] can be front principal planes [3] and front principal plane [3] joins, and also can be that back interarea [4] joins with back interarea [4], as Fig. 2, Figure 10,12, Figure 13, shown in; Can also be that front principal plane [3] joins with back interarea [4], as Figure 11, shown in Figure 14.Forming a plurality of side projections between two adjacent packing sheets is polygonal interconnection [10], as shown in Figure 2.The interarea that constitutes herringbone unit [1] can be a continuous level, and it is shaped as a concave polygon, as shown in Figure 7; Can be interrupted plane also, be shaped as the quadrangle or the recessed pentagon of period profile, as Fig. 8, shown in Figure 9; It can also be arc surface.And can allow front principal plane [3] identical or different with the shape of back interarea [4].Muscle sheet [5] shape that constitutes herringbone unit [1] can be quadrangle or triangle, can be the plane, also can be arc surface, can also with the single arc surface of the common shape of interarea.The angle β of adjacent herringbone unit [1] can be identical, also can be different.On interarea [3], [4] and the muscle sheet [5] of herringbone unit [1], ripplet, reticulate pattern, decorative pattern or pit can be processed with, also some apertures or acanthopore can be processed with.
