Abstract
The utility model provides a high-efficiency liquid distributor, comprising a foam separator, a first stage distributing groove, and a second distributing groove. A stainless steel mesh is arranged on a lower liquid outlet of the groove to filter impurity to prevent the fluid bore from being blocked and caused the inhomogeneous distribution, as a result, the defect and the insufficiency of the prior art are solved, wherein, the anti-foam groove, the first stage distributing groove, and the second stage distributing groove are characterized in that the resistance of staining and blocking is strong, the separating rate of the free section is high, and the high-efficiency liquid distributor is suite for a distillation column for pressure reducing operation, particularly a distillation column for dry type pressure reducing operation. The high-efficiency liquid distributor overcomes the problem that entrainment is produced by the secondary gasification in the column. The utility model has the advantages that the product quality can be improved, the collection efficiency can be increased and the pressure can be decreased to achieve the purpose of saving energy.
Description
The utility model relates to a kind of liquid distribution trough of oil product vacuum distillation tower.
Liquid distribution trough is the crucial intraware of packed tower, and the quality of liquid initial distribution in tower directly affects the operating efficiency of packed tower.The at present domestic liquid distribution trough that is used in the oil product destilling tower can be divided into disc type, nozzle formula, calandria etc., do not satisfy the specification requirement of oil product distillation to a certain extent, especially dry type decompression technology, no matter fuel type or lubricated oil type vacuum distillation tower, it is many that it extracts side line out, packed height little (being generally 1.5-2.5 rice), liquid spraying density is little, and the performance of filler is difficult to performance.Show that the filler pressure drop is big in process of production, the energy consumption height easily produces entrainment, and the product degree of overlapping is big, and is of poor quality, and yield is low, and is of poor benefits.Recycle product is carried with pump, and when filling in pipeline, because of disturbance is big, especially decompression operation easily produces a large amount of foams, will influence the normal drainage of distributor cell wall liquid flow hole.
The purpose of this utility model is to provide a kind of efficient liquid distributor, and it is made of foam separator, I and II distributing slot, thereby overcomes the shortcomings and deficiencies of above-mentioned prior art.
The utility model has designed unique foam separator, in the lower liquid exit of its groove stainless steel filtering net is set, and to filter out impurities, prevents that liquid flow hole is blocked, and causes skewness.
The liquid flow hole that is opened in secondary distributing slot side as sediment space, prevents that liquid stream is blocked apart from bottom land 40-100 millimeter.For making liquid spraying point uniform regularly, in the one-level distributing slot, also be provided with two row's catheters, have liquid flow hole in the pipe.The spray design of counting satisfied efficient structured packing 250Y to spray o'clock greater than 300 o'clock/m
2Specification requirement.Owing to flow in the air-flow shunting, reduce pressure and fall, prevent the generation of local liquid flooding.Liquid flow hole is opened at cell wall, and groove is programmable narrow, make distributor free cross-section branch rate greater than the 62%(high efficiency packing require＞50%), satisfied the specification requirement of dry vacuum distillation to liquid distribution trough.
The secondary distributing slot is offered two discharge opeing discharge orifices (on arrange φ 8-12 millimeter, following row φ 2-4 millimeter), has increased operating flexibility, has satisfied the bigger variation for the treatment of capacity, and the design of catheter has guaranteed the drop accurate placement that the cell wall liquid flow hole is discharged, and evenly distributes.
For guaranteeing the influence of groove internal cause liquid level drop to distributing and being caused, design is limited in liquid flow velocity in the groove within 0.2 meter per second.
Hanging beam of the present utility model makes catheter shorten to the distance of draining plate between the tower packing end face, makes the catheter dripping drops avoid the interference of the high velocity air of rising in the tower, guarantees the drop accurate placement, is evenly distributed.In these characteristics also can make filler and distributor in addition part is packed tower into from same manhole, reduce the height of tower, open manhole less, simplified structure, in same installing space, adopt hanging beam can increase the distributor upper space, make the interior uprising gas of tower have enough spaces evenly to be distributed, improve filler efficient.

Describe the utility model in detail below in conjunction with accompanying drawing: such as Fig. 1,2, the packed tower inwall is fixed with bearing 9,10, one-level distributing slot 2 is connected with bearing 9, and its both sides connect respectively several secondary distributing slots 3, and secondary distributing slot 3 is hung and is fixed on the bearing 10 by hanger 11,12 respectively. The top of I and II distributing slot is provided with foam breaking groove 1, and the below is provided with draining plate 8. I and II distributing slot sidewall is respectively equipped with catheter 6,7, and has upper and lower liquid hole 4,5 on the distribution cell wall in catheter. Draining plate 8 for the annular screen that is obliquely installed at packed tower axis angle at 45 °. One side of foam breaking groove 1 is provided with filter screen 13.
One-level is connected with flange with the secondary distributing slot, and hanger, bearing are equipped with adjusting bolt, and in order to fixing secondary distributing slot, prior being regulates to guarantee the distributor installation level by bolt.
Liquid distribution trough described in the utility model is compared with nozzle type, has and does not stop up, and does not produce the characteristics of entrainment because of secondary vaporizing.
Draining plate and tower axle structure angle at 45 °, behind each catheter whereabouts liquid contact draining plate face, because action of gravitation, on the plate face, can form a parabolic isometric line segment, the slave plate face falls, certainly distribution uniform filling therewith cooperates, and realizes the distribution from point to face, improves the overall efficiency of filler.
The utlity model has good assembling, but outer pre-assembled the checking on the quality of tower body. Its skewness rate is surveyed in cold mould experiment, through adjusting, generally can guarantee to distribute and all spend requirement. Liquid distribution trough structure and its resultant effect of characteristics of installing are the suitableeest oil product vacuum tower, especially the distillation procedure of dry type decompression.
Embodiment: in withdrawing fluid enters foam breaking groove 1, flow into one-level distributing slot 2 behind filter screen 13 foam removal filter residues, liquid enters secondary distributing slot 3 through distributing once more.The I and II distributing slot is communicated with.The liquid liquid hole on catheter again makes liquid segmentation cloth, and liquid falls from catheter 6,7, and accurate, well-regulated dropping on the draining plate 8 makes liquid become the line distribution by point.
