Description

The double width filler

The utility model relates to a kind of double width filler, and it belongs to the innovation of structured packings that adopt in the field such as chemical industry.

The common filler that is used for chemical field has dumped 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 regular corrugation filler, its each cycle ripple is made up of two continuous planes, the liquid and gas stream of filler is subjected to the restriction on ripple plane, and flux is affected, weak point such as caused that the big and efficient of pressure drop can not be given full play to.

The purpose of this utility model is to provide a kind of novel structured packing-double width filler.This filler has unobstructed gas-liquid channel, has improved the gas-liquid contact condition effectively, thereby has better serviceability.

In order to achieve the above object, the utility model is realized by following proposal: adopt metal or nonmetallic thin slice or silk screen, make the double width filler through punching press or roll-in, it is characterized in that: alongst be shaped on alternately quadrangle square hole arrangement units and linkage unit on each packing sheet of filler, quadrangle square hole arrangement units and linkage unit intersect the sideline, unit, and sideline, unit and packing sheet end line inclination angle are α=20～90 °; Each quadrangle square hole arrangement units all is to constitute front principal plane, back interarea and adjacent quadrangle square hole of two muscle sheets formation by two interareas 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; Preceding folding line or back folding line and element sides line parallel, muscle sheet sideline is vertical with the sideline, unit.The dihedral angle that muscle sheet and front principal plane or back interarea form is δ=100～180 °; The angle of front principal plane or back interarea and packing sheet datum plane is γ=0～90 °; Linkage unit is a complete plane, and the angle of it and packing sheet datum plane is θ=20～90 °; The feature of above-mentioned double width filler also is: front principal plane and back interarea can all be continuous levels, and it is shaped as a concave polygon; Also can be that one of them is a continuous level, and another is interrupted plane, it be shaped as the rectangle of period profile; Can all be interrupted plane also, its shape be the rectangle of period profile; Forming a plurality of side projections between two adjacent packing sheets is polygonal interconnection; Less ripple, reticulate pattern, decorative pattern or pit can be processed on each interarea of composition double width filler and the muscle sheet, also some apertures or acanthopore can be processed with.

Wherein [1] is quadrangle square hole arrangement units; [2] be linkage unit; [3] be the sideline, unit; [4] be the packing sheet end line; [5] be front principal plane; [6] be the back interarea; [7] be the muscle sheet; [8] be preceding folding line; [9] be the back folding line; [10] be muscle sheet sideline; [11] be the quadrangle square hole; [12] be the packing sheet datum plane; [13] be interconnection.

Below with reference to the accompanying drawings the utility model is described in more detail.

Each packing sheet of double width filler is made up of spaced quadrangle square hole arrangement units [1] and linkage unit [2], quadrangle square hole arrangement units [1] and linkage unit [2] intersect sideline, unit [3], and sideline, unit [3] and packing sheet end line [4] inclination angle are α=20～90 °.Each quadrangle square hole arrangement units all is made up of two interareas parallel to each other (front principal plane [5] and back interarea [6]) and period profile and the muscle sheet [7] that is connected forward and backward interarea.Muscle sheet [7] intersects preceding folding line [8] with front principal plane [5], or is bent into arc surface; Muscle sheet [7] intersects back folding line [9] with back interarea [6], or is bent into arc surface.Preceding folding line [8] or back folding line [9] are parallel with sideline, unit [3], and muscle sheet sideline [10] is vertical with sideline, unit [3].Linkage unit [2] is a complete plane, as depicted in figs. 1 and 2.Front principal plane [5], back interarea [6] and adjacent two muscle sheets [7] form a quadrangle square hole [11], and the dihedral angle that muscle sheet [7] and front principal plane [5] or back interarea [6] form is δ=100～180 °.Front principal plane [5] or back interarea [6] and the angle of packing sheet datum plane [12] are γ=0～90 °, and the angle of linkage unit [2] and packing sheet datum plane [12] is θ=20～90 °.Front principal plane [5], back interarea [6] can be parallel with packing sheet datum plane [12], shown in Fig. 2,3,4; Also can be not parallel, as shown in Figure 5 with packing sheet datum plane [12].Front principal plane [5] and back interarea [6] can all be continuous levels, and it is shaped as a concave polygon, as Fig. 2, Fig. 5 and shown in Figure 6; Also one of them is a continuous level, and another is interrupted plane, and it is shaped as the rectangle of period profile, as Fig. 3 and shown in Figure 7; Can all be interrupted plane also, its shape be the rectangle of period profile, as Fig. 4 and shown in Figure 7.Forming a plurality of side projections between two adjacent packing sheets is polygonal interconnection [13], as shown in Figure 2.
