Description

Tower packing element

The present invention relates to be used in a kind of Chemical Manufacture tower packing element such as application scenarios such as mass transfer and heat transfers.This packing element that is usually used in the irregular stacking filler has a very big surface area contacts gas and liquid, can make the gas-phase pressure drop in the tower low as much as possible simultaneously.This packing element generally is piled into a vertical king-post and is had the suitable degree of depth, thereby the packing element in the bottom just has distortion or the trend that is crushed, does not wish the barometric gradient that produces thereby cause the resistance of the tower of flowing through to increase and form one in tower.

Thereby packing element just need be designed to a kind ofly can prevent distortion, an opening structure and the structure of high surface area can be provided again simultaneously very much.

Bao Er's ring and Rasching ring are typical above this structures.As its name suggests, they be cylinder-like structure and have various in prominent part to increase surface area.Such structure can prevent crushing, but can cause bad pressure drop in some application scenario.And for preferably adopting such as USP P.4 303,599 in more such application scenarios; 4,333,892; And 4,576, the structure that has more opening described in 763, they all are the curved metal thin-slab structure basically, have the one or more bar sheet elements that cut down from arc sheetmetal, this member is by crooked to admit a curved surface relative with the arc cambered surface and form bridge joint between the beginning of arc in arc.These bridge joint rings mainly be to constitute extra flow channel for liquids and the surface and prevent that all packing elements are stacked as " nesting ".For weight reduction, they are to make with the metal of thin specification, thereby its non-deformability is relatively poor.And want weight reduction also is very important, and this is because the weight of single packing element is light more, and the power that adds up that is applied on the packing element at the king-post base portion place of filling up packing element is just more little, and power is more little just to be not easy distortion more and to be crushed.But thin metal still makes packing element more yielding.Thereby, inevitably will make packing element lighter and have have between the sufficient intensity that bears certain load one compromise.

Now developed a kind of design of novelty, it can improve the non-deformability of the arc packing element of irregular stacking greatly.That this design is applicable to is existing, the accumulation formula packing element of above any kind, and arbitrary type is all had similar advantage.All design features of the present invention can be with traditional manufacturing equipment, finishes under the situation of extra charge need not.Why particularly useful this design feature is, is because it can make packing element have more rigidity, simultaneously can be more lightly.

The packing element of irregular stacking of the present invention has an arc body and bridge joint ring that at least one extends between the beginning of the cambered surface of body, described bridge joint ring has a curved surface relative with the cambered surface of body, between arc body and bridge joint ring, to seal a space, described body has a burr that extends basically on cambered surface length, to provide a projection in the space of arc body and the qualification of bridge joint ring.In order to increase extra intensity, the burr that preferably on the bridge joint ring, is provided with similarly, extends along the length of whole ring basically, this burr forms a corresponding groove on the apparent surface of bridge joint ring.

Burr on the body can be the form of adding up from the body distortion, but more frequent is basically along the form of grooves of being out of shape on the convex surface length of body (just around whole cambered surface), has so just formed the burr of a projection on the opposite of arc body (concave surface).Groove then can also can be shaped outside arc from the arc internal shaping.This packing element has the groove that is formed in the arc, and (like this bubble just appears on the concave surface of arc body), like this, liquid just can not be trapped in the bubble.Such burr if necessary more than one can be shaped.

The groove that is formed in the bridge joint ring can be formed on convex surface or the concave surface, and is normally very shallow, its degree of depth roughly be no more than ring width 50%, if can be no more than 25%, for example can be better in the words of about scope of 10% to 25%.The effect of groove is the intensity that increases ring, but the excessive deformation of the metal strip of formation ring has played reaction in this, particularly under the thin situation of metal strip.

Except groove recited above, on the bridge joint ring, also can establish flange in addition.On body, also can establish flange in addition to strengthen its non-deformability.

Except the feature of above-described all grooves and burr, packing element can also comprise one or more pairs of prominent parts that extend in body and space that one or more bridge joint ring seals become, one end of every pair of prominent part is then linking to each other with the bridge joint ring near the relative end of bridge joint ring, and this position of described prominent part and orientation are in order to allow them be darted in body and the space that the bridge joint ring seal becomes.The premiere feature of these prominent parts is that some extra dropping points are provided in packing element.In a kind of preferable form of the present invention, described prominent part is a kind of lug that forms from the bridge joint ring material, and this forms by cutting part inwardly being cut, is out of shape and it being close but preferably not contacting.Yet, be understandable that lug also can be to weld or link on a body or the bridge joint ring with other method of attachment.For the consideration on the cost, such connection directly stamps out from individual sheet metal and and then comes its net shape that correctly is configured as packing element well with regard to being not so good as.Lug is prominent relative to one another to be established, and its angle preferably is no more than 90 °, for example greatly about 60 to 75 °.

Described prominent part can be shaped from the material of arcuate member own, that is, on a flat silver, cut out prominent part shape and and then bend to required structure, the material of the well cutting plane from arcuate member to be shifted out before bending forming or simultaneously.Gratifyingly be, so a kind of packing element has a lot of benefits in making production process, and it only needs one simple, mechanization, continuous stamping process to finish.

Except above-described prominent part, arcuate member of the present invention can also comprise all features of other any arc packing element of the prior art, comprising the use of a pair of bridge joint ring.This arcuate member also can have some other lug, and they do not contact each other and have only constituted new contact surface and runner.

In a preferred embodiment of the present invention, the packing element that comprises arc body, one or more bridge joint rings and a plurality of prominent parts is by individual metal strip direct forming, promptly, earlier silver vertically on cut out suitable joint-cutting, like this, curving inwardly when forming arc, can be the bridge joint ring at the space internal shaping of arc body sealing with at least one silver, the existing silver in the bridge joint ring can also be configured as the prominent part in the space between body and bridge joint ring.

Becoming burr on the present invention's the body of feature and the groove on the bridge joint ring can be shaped simultaneously, or be shaped in succession.Because the burr operation on one or more bridge joint rings can be carried out on unfashioned sheet material, thereby all dimpled grain can be arranged on the whole length of sheet material.Like this, when the shaping whole member, burr can be continuously extends on one or more bridge joint rings from the end of body, returns the relative other end of body.

The curvature of arcuate member needn't be very even, like this it just have one with the perpendicular arc of the axis of arcuate member or the section of circumferential.In fact more satisfactory is as USP4, described in 303,599 like that, the cross section of arcuate member is a paraboloidal.

Fig. 1 is the end view along the arcuate member of the present invention's of axis direction first embodiment.

Shown in Fig. 2 is the metal sheet that has line of cut on it, and it can further be configured as the arcuate member shown in Fig. 1, but features such as groove of adding after the cutting of not shown sheet material or burr.

Fig. 3 is the side view of this packing element perpendicular to its axis.

Shown in Fig. 4 is a metal sheet that has arcuate member line of cut, that be suitable for the production preferred construction on it.

Describe the present invention below in conjunction with accompanying drawing, should be appreciated that, the description that all embodiment of the present invention did is not limited to some extent to essence protection domain of the present invention.

Among Fig. 1, a packing element 1, it comprises a body 2, and the burr 6 and the end 3 of longitudinal extension arranged on it; Two bridge joint rings 4, they have similar and relative with body part curved surface, and this bridge joint ring links to each other with arcuate member in the place near both ends 3, and the two ends cross-over connection is got up.These bridge joint rings are provided with groove 7.Prominent part 5 also is shaped and is darted in the space of body and bridge joint interannular from the bridge joint ring.The outer side edges of arc body is provided with flange 8.

One flat sheet has been shown among Fig. 2, has been shaped on line of cut above, like this should flat board just can be crooked, be deformed into the arcuate member shown in Fig. 1.
