Description
Technical field
This utility model belongs to column plate field, the column plate of a kind of anti-liquid flooding.
Background technology
The tower that diameter is certain, it is limited for being available for the biphase free-pouring cross section of air-liquid.If the flow of alternative one increases to certain limit, the liquid in downspout just can not flow down swimmingly；When the liquid in pipe completely arrives the overflow weir crest of top plate, just to overflow to top plate, produce abnormal hydrops, finally may result between two-ply and be full of by foam solution.This phenomenon, referred to as liquid flooding.If liquid flooding is excessively serious, hydraulically full in tower tray, tower, now it is flooding.When forming liquid flooding or flooding in tower, gas-liquid two-phase will be unable to be normally carried out mass transter.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of liquid that liquid is unnecessary when completely arriving certain altitude on tower tray will flow directly out tower tray by mozzle, directly drop to flow out at the bottom of tower, it is to avoid liquid level too high formation liquid flooding on tower tray, improve the column plate of the anti-liquid flooding of gas-liquid mass transter efficiency.
For achieving the above object, this utility model provides following technical scheme: the column plate of a kind of anti-liquid flooding, including tower tray, downflow weir and downspout, described tower tray is provided with the most penetrating mozzle, described mozzle is provided with ball-cock assembly.
Further described ball-cock assembly includes rotor plate, drive link and ball float, described rotor plate is positioned at mozzle and hinged with mozzle, described drive link includes cross bar and montant, described montant one end is hinged with rotor plate, the other end stretches out above mozzle hinged with cross bar, and the other end of cross bar correspondence montant connects ball float, is provided with pole between cross bar and tower tray, cross bar is hinged with pole, is additionally provided with the locating piece preventing rotor plate to be rotated up in described mozzle.
Further described ball float is positioned at downspout top position.
Further described montant is expansion link.
Tower tray, mozzle lower opening inward collapsible are extended in the lower section of further described mozzle, and the opening below mozzle is less than mozzle upper opening.
Further described mozzle is positioned at the center of tower tray.
Compared with prior art, the beneficial effects of the utility model are: by setting up mozzle on tower tray, when on tower tray, liquid levels is too high, liquid will make ball float float, and drive rotor plate to open by drive link, unnecessary liquid will flow into mozzle, rotor plate in mozzle is opened, and mozzle turns on, and unnecessary liquid is directly down to the bottom of tower and is flowed out tower by mozzle, avoid the formation of Concerning Flooding Phenomenon, it is ensured that the normal mass transter of gas-liquid；When liquid levels does not exceeds mozzle upper end, ball float is not floated up by support liquid, and rotor plate is closed mozzle enclosed cross, it is to avoid gas by here by.

Detailed description of the invention
Embodiment referring to figs. 1 through the column plate of Fig. 3 liquid flooding anti-to this utility model is described further.
The column plate of a kind of anti-liquid flooding, including tower tray 1, downflow weir 5 and downspout 2, described tower tray 1 is provided with the most penetrating mozzle 6, described mozzle 6 is provided with ball float 71 valve.
When on tower tray 1, liquid is too much, ball float 71 valve will be made to open, i.e. mozzle 6 turns on, unnecessary liquid will flow at the bottom of tower by mozzle 6, avoiding the formation of liquid flooding and affect mass transter, when liquid level is low, ball float 71 valve will turn off, avoid gas to be flowed directly out by mozzle 6, do not form mass transter with liquid.
Preferred described ball float 71 valve of the present embodiment includes rotor plate 76, drive link and ball float 71, described rotor plate 76 is positioned at mozzle 6 and hinged with mozzle 6, described drive link includes cross bar 72 and montant 75, described montant 75 one end is hinged with rotor plate 76, the other end stretches out above mozzle 6 hinged with cross bar 72, the other end of the corresponding montant 75 of cross bar 72 connects ball float 71, pole 17 it is provided with between cross bar 72 and tower tray 1, cross bar 72 is hinged with pole 17, is additionally provided with the locating piece 67 preventing rotor plate 76 to be rotated up in described mozzle 6.
As shown in Figure 3, when liquid level is higher, promotion ball float 71 is moved upward along c direction, and then drive drive link motion, montant 75 will promote rotor plate 76 to rotate along b direction, making mozzle 6 in the conduction state, otherwise rotor plate 76 blocks mozzle 6, when wherein locating piece 67 can make liquid level low, rotor plate 76 keeps mozzle 6 closed state.
Described ball float 71 is positioned at downspout 2 top position, and in use, usual polylith column plate is the most vertically arranged, no liquid landing above this tower tray 1 downspout 2, liquid can be avoided to drop on ball float 71 affect ball float 71 normally working.
The preferred described montant 75 of the present embodiment is expansion link, by length and then the elemental height of adjustable ball float 71 of adjustable telescopic rod, to adjust according to different use occasions, improves range.
Tower tray 1 is extended in the lower section of the preferred described mozzle 6 of the present embodiment, mozzle 6 lower opening inward collapsible, opening below mozzle 6 is less than mozzle 6 upper opening, described mozzle 6 is positioned at the center of tower tray 1, when mozzle 6 is opened, ensureing that mozzle 6 can be conducted mutually, liquid can directly be flow at the bottom of tower by mozzle 6.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
