Abstract
The utility model provides the filler pressing of a kind of band from distributed function, is applied to chemical separating equipment, comprise cell structure and the liquid that is made up of surface distributed dish, drain structure from distributed architecture.The sub-thread liquid diverting flow falling into described surface distributed dish can be become the tiny liquid stream of multiply from distributed architecture by described liquid, and liquid spraying point number amount is increased greatly.For the rectifying column easily blocking up system or low liquid spraying density, the utility model is fixed except having filler and except position-limiting action, also has and increase liquid distribution point quantity, improve liquid distribution effect, improve gas-liquid mass transfer efficiency, anti-clogging and do not increase the feature of Whole Equipment height.
Description
Technical field
The utility model belongs to chemical filler tower internals equipment technical field, relates to a kind of new packing trim ring, and specifically a kind of band is from the filler pressing of distributed function.
Background technology
In industries such as petrochemical industry, fine chemistry industry, food, medicine and environmental protection, tower all belongs to important unit, it is widely used in the unit operations such as distillation, absorption, extraction, washing, heat transfer, and therefore the research of tower enjoys the concern of Chinese scholars always.In recent years, along with the development of tower technology, tower internals technology is also constantly developed and improves, and various new-pattern tray emerges in an endless stream.But requisite device in this packed tower of filler pressing, does not have structural innovation for many years substantially, only have single filler is fixed and spacing function all the time.
In the design process of tower, for easily blocking up system, for preventing liquid distribution trough from blocking, it is larger that distribution hole aperture is often designed, and under the condition that sprinkle density is constant, certainly will cause the minimizing of distribution hole sum like this; In the rectifying column of the low consumption of the liquid loads such as high vacuum, liquid spraying density is less, and the distribution hole sum of distributor is also less.And for the high filler of separation accuracy, need accurate liquid distribution trough to match.Adopt the liquid distribution trough of few distributed points that the separative efficiency of filler can be caused to reduce under above two kinds of operational circumstances, affect gas-liquid mass transfer efficiency in tower; And those baroque liquid distribution troughs can increase the whole height of equipment, improve equipment investment.So need a kind of structure simple and the low liquid distribution trough of occupy-place, can support the use with conventional distributor, also can be used alone, reach liquid uniform or increase the object that liquid distribution counts.
Utility model content
In view of this, the utility model is intended to propose one can increase liquid distribution point quantity, improves liquid distribution effect, improves gas-liquid mass transfer efficiency, anti-clogging and do not increase the filler pressing of Whole Equipment height, to solve the defect existed in prior art.
For achieving the above object, the technical solution of the utility model is achieved in that
Be with the filler pressing from distributed function, comprise cell structure, described cell structure is fixed with liquid from distributed architecture; Described liquid comprises surface distributed dish and drain structure from distributed architecture.
Further, described surface distributed dish is the hollow lug that an edge is provided with multiple cloth liquid angle, is fixed on described cell structure; Described drain structure is fixed on described surface distributed dish.
Further, described surface distributed disk center is just to upper liquid distributed points; Described surface distributed dish level is installed.
Further, the liquid distribution of appearance and size needed for upper liquid distributed points position, quantity and below filler of described surface distributed dish is counted and is adjusted.
Further, described drain structure is open drain structure or overflow-type drain structure.
Further, described drain structure is multistage composite drain structure.
Relative to existing conventional fillers trim ring, the utility model in use, after sub-thread liquid wanders surface distributed disk center, flow to surface distributed dish surrounding under the guide functions of drain structure, finally form the tiny liquid stream of multiply at multiple cloth liquid angle place and fall in the filler of below, thus reach increase liquid distribution point quantity, improve liquid distribution effect, the object of strengthening gas-liquid mass transfer.Because the liquid on described surface distributed dish is by flowing freely the effect reaching shunting, without easy bridging structure, so the utility model has good performance of anti-blockage.Structure simultaneously due to surface distributed dish and drain structure is comparatively simple, highly low, makes full use of filler pressing cell structure superjacent air space, does not increase spatial altitude in tower.

Detailed description of the invention
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Embodiment 1
As shown in Figure 3, open liquid guiding liquid is the thin slice that there is multiple cloth liquid angle at the low and edge of high surrounding in centre from the surface distributed dish of distributed architecture, surface distributed dish in the present embodiment has four cloth liquid angles, fixed with the solid welding of surface distributed dish four arc edge points respectively bottom four drain sheets.In actual use, after sub-thread liquid wanders surface distributed disk center, under the guide functions of drain sheet, liquid flows to surface distributed dish surrounding, final from four cloth liquid angular fluxs, liquid distribution o'clock increases to four points from a point, thus reaches increase liquid distribution point quantity, improve liquid distribution effect, improve the object of gas-liquid mass transfer efficiency.
As Fig. 1, shown in 2, liquid is welded on cell structure from distributed architecture.
Embodiment 2
As shown in Figure 6, overflow liquid guiding liquid is the thin slice that there is multiple cloth liquid angle at the low and edge of high surrounding in centre from the surface distributed dish of distributed architecture, and the surface distributed dish in the present embodiment has eight cloth liquid angles.Drain structure is the ring segment having gap, and the corresponding gap in each cloth liquid angle, drain sheet is welded in surface distributed dish upper surface.In actual use, after sub-thread liquid wanders surface distributed disk center, be collected together by annular drain sheet, liquid level raises gradually and finally goes out from the gap overflow drain sheet, due to the cloth liquid angle of the positive corresponding surface distributed dish of each gap, so liquid distribution o'clock increases to eight points from a point, thus reach increase liquid distribution point quantity, improve liquid distribution effect, improve the object of gas-liquid mass transfer efficiency.
As Fig. 4, shown in 5, liquid is welded on cell structure from distributed architecture.
