Abstract
The invention discloses polygonal edgefold tilting-type concave liquid receiving discs which prevent the solid granule blocking at an outlet of a downcomer. The number of the liquid receiving discs is changed as the variation of overflow amount; the polygonal edgefold tilting-type concave liquid receiving discs comprise tower plates connected with the liquid receiving discs, tilting polygonal folded edges back on to the tower wall sides and concave base plates connected with the tilting polygonal folded edges.
Description
Technical field
The present invention relates to adopt polygon flanging tilting recessed seal pan, relate generally to the tower internals in the systems such as chemical plant installations rectifying, extraction, absorption.
Background technology
The position of accepting the liquid under the lastblock plate current on the column plate is called seal pot.Seal pot has plate shaped and two kinds of structural shapes of spill, the column plate that common recessed seal pan links to each other with column plate is a straight line but not polygon flanging, and the dented part of seal pot straight line is vertical 90 ° but not tilting, can circulate to guarantee liquid phase according to the gap that gas-liquid load designs between downspout and the seal pot during design tower internals, and to guarantee that also vapour phase can not pass through, when in little liquid flow rate and the liquid phase solid particle being arranged, will spill design contradiction cruelly, the crack can not form fluid-tight too greatly at the bottom of the downspout, the too little solid particle in crack, the end is accumulation and obstruction downspout easily, though common recessed seal pan can guarantee fluid-tight and circulation, but can not well cooperate with polygon flanging inclination downspout, thereby can not guarantee to have on the column plate good liquid phase to flow and cause the liquid phase dead band, and the solid particle that can not guarantee to enter in the downspout is in time discharged downspout.
Summary of the invention
The objective of the invention is, propose a kind of for preventing from forming at the downcomer outlet port place the special polygon flanging inclination recessed seal pan of solid particle clogging, it is very little that polygon flanging tilting recessed seal pan crack, the relative end can be done, but " very big " that can do on the level so just can guarantee that solid particle is not blocked.Especially polygon flanging tilting recessed seal pan is to increase downspout and go out open height relatively by increasing by a polygon flanging Baltimore groove, thereby prevents from forming at the downcomer outlet port place purpose of solid particle clogging.
Technical scheme of the present invention: a kind of polygon flanging tilting recessed seal pan, seal pot is provided with a polygon flanging Baltimore groove, increase downspout and go out open height relatively, thereby prevent from forming at the downcomer outlet port place purpose of solid particle clogging, polygon flanging tilting recessed seal pan comprises the column plate that joins with seal pot, the spill chassis that links to each other with inclination polygon flanging; The downcomer outlet port of polygon flanging is mouthful little external inclined type in the big end.
Further, seal pot is polygon flanging recessed seal pan, and the seal pot degree of depth is 10-80mm.
Further, the downcomer outlet port of polygon flanging, polygon flanging are counted 3-8 and are not waited.
Further, the polygon flanging is provided with flanging 6-16 in the outside that downspout distributes and does not wait, and it respectively distributes 3-8 in both sides.
Further, the polygon flanging is corresponding one by one with the outer side edgefold number that downspout distributes.Further, the downcomer outlet port of polygon flanging is mouthful external inclined type that the big end is little, and the angle of inclination is 10-80 ° with vertical horizontal angle.
Operation principle of the present invention is as follows: when liquid phase flows down from downspout; enter recessed seal pan; liquid phase is tilted to along the polygon flanging that tilts and flows to column plate afterwards; in this process; when having solid particle in the liquid phase and flow through herein; because " very big " that the column plate that links to each other with the polygon flanging and the distance on downspout base can be done on level; and the polygon flanging that tilts can reduce the resistance that continues to move up when solid particle arrives the groove dead angle; therefore solid particle can be easy to flow on the tower tray with liquid phase, and so design just can reach and prevent in downcomer outlet port place formation solid particle clogging.
Beneficial effect of the present invention is: the downcomer outlet port place forms the special polygon flanging inclination recessed seal pan of solid particle clogging, it is very little that polygon flanging tilting recessed seal pan crack, the relative end can be done, but " very big " that can do on the level so just can guarantee that solid particle is not blocked.Especially polygon flanging tilting recessed seal pan is to increase downspout and go out open height relatively by increasing by a polygon flanging Baltimore groove, thereby prevents from forming at the downcomer outlet port place purpose of solid particle clogging.
Description of drawings
Fig. 1 is polygon flanging tilting recessed seal pan vertical view;
Fig. 2 is polygon flanging tilting recessed seal pan schematic perspective view.
1 is the column plate that joins with seal pot; 2 is that the tower wall rolls oblique polygon flanging dorsad; The 3 spill chassis that link to each other with inclination polygon flanging; 4 is downspout.
The specific embodiment:
Below in conjunction with embodiment and accompanying drawing the present invention is done further explanation.Should be appreciated that following examples only are intended to explanation, should not be regarded as limitation of the scope of the invention.
Can illustrate that by accompanying drawing the present invention places the column plate 1 that joins with seal pot in the downspout bottom, the tower wall rolls oblique polygon flanging 2 dorsad, and flanging is counted 3-8 and do not waited, and the angle of inclination is 10-80 °, the spill chassis 3 that links to each other with inclination polygon flanging.
The polygon flanging of polygon flanging tilting recessed seal pan is to match with the polygon flanging of polygon flanging downspout, guarantees to have on the column plate good liquid phase to flow.Every dorsad the tower wall roll oblique polygon flanging 2 with 3 groups on the seal pot column plate 1 that joins and the spill chassis that links to each other with inclination polygon flanging to seal welding, guarantee that the tower wall rolls the angle of inclination of oblique polygon flanging 2 between 10-80 ° dorsad, every dorsad the tower wall roll seal welding between the oblique polygon flanging 2, assurance can not be leaked gas.
