Abstract

The utility model discloses a liquid distributor for packed columns, comprising a liquid inlet tube, a packaging box, a bearing, a liquid distributing box and a plurality of nozzles. The liquid distributing box can rotate round the liquid inlet tube according to the bearing, the packaging box is used for the sealing between the liquid inlet tube and the liquid distributing box, and a spiral arm tube is arranged on the liquid distributing box. When a nozzle distributed on the spiral arm tube ejects working solution, a generated reactive force makes the liquid distributor automatically rotate and evenly distribute liquid, compared with a fixed type liquid distributor, the utility model is greatly improved in the condition of liquid distribution is greatly improved, and the production efficiency and productivity of the packed columns can be raised.

Description

A kind of packed tower liquid distributor

The utility model relates to the liquid distributor in the various packed towers in fields such as being applied to chemical industry, oil, medicine, environmental protection.

The operation effect of packed tower depends on the structure and the performance of liquid distributor to a great extent.Liquid distributor that generally uses such as shower nozzle, water chestnut pipe, splitter box etc. are fixed liquid distributor at present.Its operation principle all is earlier the main flow liquid dispersion to be become many thin strand of liquid streams, fixedly trickles down on some fixing points on the plane, filler top again.The thin strand of liquid stream that these are trickled down on the filler end face utilizes filler to contact the horizontal or obliquely flow that is produced each other closely again, carries out secondary distribution, finally reaches the equally distributed purpose of fluid.This fixed liquid distributor exists many weak points; 1, is difficult to accomplish that the even cloth of liquid is sprinkled upon on the whole tower section; 2, in the process of carrying out the liquid secondary distribution, filler does not reach all wetting as yet in the tower, can not accomplish that more there is liquid flow on the tower packing surface, therefore at the packed tower top, it is inoperative having quite a few tower packing, has in fact equaled to lose the effective depth of tower; 3, when sprinkle density is too small, owing to can not guarantee the wetting of most of filler, even make the whole packed tower can't operate as normal.

The purpose of this utility model will provide a kind of packed tower liquid distributor exactly, and it can utilize the overbottom pressure of the liquid working medium of imported fill tower to be power, makes liquid distributor make 360 ° of rotation cloth liquid, thereby guarantees the even cloth liquid of the full section of tower packing.

For achieving the above object, the packed tower liquid distributor that the utility model is designed is at its feed tube bottom design one flange, plane bearing is installed on the flange, the plane bearing upper support has stuffing box, and airtight and watertight padding is contained in the stuffing box, is compressed in case leakage by gland; And the bottom of the top of its separating box and stuffing box connects firmly, and separating box and feed tube are connected as one, and the separating box and the stuffing box that connect firmly together can rotate around feed tube according to plane bearing; Lower horizontal at separating box is symmetrically installed with some spiral arm pipes, on the spiral arm pipe and separating box bottom is equipped with a plurality of nozzles, and hydraulic fluid is transported to separating box by feed tube, penetrates by nozzle to the spiral arm pipe again, consequent reaction force then drives liquid distributor rotation, evenly cloth liquid.

In order to make liquid distributor that enough rotary thrusts not only be arranged, and require its ejection hydraulic fluid drop point to change minimum, the utility model will be installed in the center line of the nozzle on the spiral arm pipe and the angle of horizontal plane is adjusted in ° scope of α=0～90, and outwards pass from pivot, the α of the nozzle of being arranged contends decrescence little.

Advantage of the present utility model is to adopt automatic rotation cloth liquid, by the nozzle of rotation and different nozzle angles hydraulic fluid is trickled down equably on plane, tower packing top, and hydraulic fluid fall also can produce behind the plane, tower packing top mobile, thereby guaranteed that hydraulic fluid is distributed on the whole tower section, greatly improved the wetness degree of filler in the tower, can reduce the total height of tower packing height and tower significantly, reduce construction cost.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is the structural representation of the utility model liquid distributor.

Fig. 2 be among Fig. 1 A-A to amplifying cut-away view.

Liquid distributor shown in the figure comprises feed tube 1 and separating box 8 and keeps the above-mentioned stuffing box 4 of sealing between the two.Feed tube 1 has flange 6 for adapting to the fixed-piping of chemical industry technological requirement in its bottom design, and plane bearing 5 is installed on the flange 6, and plane bearing 5 upper supports stuffing box 4, and airtight and watertight padding 3 is housed in the stuffing box 4, and airtight and watertight padding 3 is tight by gland 2 lids; The top of stuffing box 4 bottoms and separating box 8 is fixedly connected with flange or screw thread, and the connection place can be with the sealing gasket sealing in case liquid leakage.Lower horizontal at separating box 8 is symmetrically installed with four spiral arm pipes 7, be respectively equipped with a plurality of nozzles 9 on the bottom of separating box 8 and four spiral arm pipes 7, nozzle 9 can adopt the shrinkage type conventional nozzle, its quantity, bore, arrangement pitch then by the bore of packed tower, cross all changing factors such as flow quantity, operating pressure and determine; The angle α of the center line of nozzle 9 and horizontal plane, can in 0～90 ° of scope, change successively, the α angle of the several nozzles in this liquid distributor pivot place is 90 °, along with mind-set is therefrom passed outward, the α of nozzle contends decrescence little, the α angle of outermost nozzle is 20 °, and the hydraulic fluid drop point changes not quite like this, and cloth liquid is very even.10 is filler Tata wall among the figure, and 11 are plane, tower packing top, from center line generally can design at 100mm in the scope of 300mm apart from S to tower packing plane 11, top of spiral arm pipe 7.During the work of this liquid distributor, the hydraulic fluid that has certain overbottom pressure makes the separating box and the stuffing box reverse rotation that are suspended on the bearing 5 from nozzle 9 ejections, realizes automatically evenly cloth liquid.Because the existing fixed liquid distributor of the aqueous condition of cloth of this liquid distributor has bigger improvement, and simple in structure, production capacity after existing packed tower is used this liquid distributor instead, can be enhanced productivity, be strengthened to low cost; After newly-designed packed tower adopts this liquid distributor, can obviously reduce the total height of tower packing height and tower.
