Abstract
The utility model discloses a liquid distributor for a packed tower. According to the liquid distributor, an annular plate is fixedly arranged on an inner wall of a tower body of the packed tower; a cylindrical distribution groove is formed below a middle pore channel of the annular plate with a distance; liquid flows down from the annular plate through the cylindrical distribution groove and is collected by cylindrical distribution groove; the groove bottom of the distribution groove is provided with a liquid redistribution pore plate with a liquid hole; the edge of the middle pore channel of the annular plate is downwards connected with a shallow small ring; the diameter of the inner ring of the cylindrical distribution groove is larger than the diameter of an inner ring of the shallow small ring; and the cylindrical distribution groove is fixed on the inner wall of the tower body of the packed tower through three vertically-arranged guide rib plates which are connected on the outer circumference wall. The liquid distributor for the packed tower has the characteristics of reasonable structure, reliable application, good using effect and the like.
Description
Technical field
The utility model relates to a kind of liquid distribution trough that is mainly used in middle-size and small-size air separation unit packed tower, belong to and establish the liquid distribution technical field in packed tower.
Background technology
In sky divides the rectifying field, can save energy and reduce the cost in running in order to save manufacturing cost and air separation unit, the raising of rectification efficiency has very important effect, and whether liquid distribution trough arranges rationally very large on the impact of rectification efficiency.Distributor used in present air separation unit is of a great variety, but the distributor of applicable middle-size and small-size air separation unit is few, and structure is reasonable not, and result of use is relatively poor.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, uses reliably, and result of use is good, is specially adapted to the liquid distribution trough of the packed tower of middle-size and small-size air separation unit.
The purpose of this utility model is achieved by the following technical solution, it is to be fixed with a ring flat-plate on the tower body inwall of a packed tower, the below, middle duct of this ring flat-plate is equipped with every sky the cylindrical shape distributing slot that flows down and catch from ring flat-plate for liquid, and the bottom land of distributing slot is one with the liquid of liquid pores distribution orifice again.
The edge, middle duct of described ring flat-plate is connected to a shallow shape ringlet downwards, and the inner ring diameter of described cylindrical shape distributing slot is greater than the inner ring diameter of described shallow shape ringlet.
Described cylindrical shape distributing slot is fixed on the tower body inwall of described packed tower on by three vertically arranged guiding gussets that are connected on outer circle wall at least.
The air separation unit packed tower is because filler has from distribution capability and wall stream effect, packed tower generally can not be greater than 15% along the liquid distribution amount in 15% scope of the diameter outside, middle-size and small-size packed tower does not even need the liquid that distributes in this zone, and has accounted for approximately 28% along flux area in the scope in the diameter outside 10%.
The utility model is arranged on gas passage in the outside of tower, has both utilized the outer space of tower, meets again the characteristic of filler itself; The Set scale of the gas-liquid channel of distributor is more easily controlled, and fluid passage is not subjected to the constraint of gas passage, makes the setting of liquid pores more flexible, has increased the distribution density of liquid.The utility model is mainly used in middle-size and small-size air separation unit, and the raising of this type of air separation unit rectification efficiency is had larger effect, have rational in infrastructure, use reliable, the characteristics such as result of use is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is ring flat-plate described in the utility model and ringlet structural representation.
Fig. 4 is described distributing slot structural representation described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, the utility model is to be fixed with a ring flat-plate 2 on tower body 1 inwall of a packed tower, 3 belows, middle duct of this ring flat-plate 2 are equipped with the cylindrical shape distributing slot 4 that flows down and catch from ring flat-plate 2 for liquid every sky, the bottom land of distributing slot 4 is one with the liquid of liquid pores distribution orifice 5 again.
Shown in Figure 3,3 edges, middle duct of described ring flat-plate 2 are connected to a shallow shape ringlet 6 downwards, and the inner ring diameter of described cylindrical shape distributing slot 4 is greater than the inner ring diameter of described shallow shape ringlet 6.
Shown in Fig. 1,2,4, described cylindrical shape distributing slot 4 is fixed on tower body 1 inwall of described packed tower on by three vertically arranged guiding gussets 7 that are connected on outer circle wall at least.
Described ring flat-plate 2 be provided for barrier liquid from the hypomere of the outer side inflow tower of tower body 1, liquid is directed in the distributing slot 4 of distributor.The below of ring flat-plate 2 arranges a ringlet 6, is used for preventing that the liquid wall by ring flat-plate 2 from flowing to the outside of tower.Guiding gusset 7 is used for the distributing slot 4 of fixed distributor, can play certain guide effect again simultaneously when distributor is installed, and guarantees the levelness that distributor is installed.
How much next definite the size of distributing slot described in the utility model is according to gas flux, and the fluid passage in groove is not subjected to the impact of gas passage, and the liquid aperture can arrange arbitrarily as required, has increased the distribution density of liquid.
Claims (3)
1. the liquid distribution trough of a packed tower, it is to be fixed with a ring flat-plate on the tower body inwall of a packed tower, the below, middle duct that it is characterized in that this ring flat-plate is equipped with every sky the cylindrical shape distributing slot that flows down and catch from ring flat-plate for liquid, and the bottom land of distributing slot is one with the liquid of liquid pores distribution orifice again.
2. the liquid distribution trough of packed tower according to claim 1, is characterized in that the edge, middle duct of described ring flat-plate is connected to a shallow shape ringlet downwards, and the inner ring diameter of described cylindrical shape distributing slot is greater than the inner ring diameter of described shallow shape ringlet.
