Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work Obtained all other embodiment is put, the range that the utility model is protected is belonged to.

Referring to shown in Fig. 1-Fig. 2, the utility model provides a kind of efficiently anti-stifled tower tray, including is mounted on 1 inside of tower wall Column plate 2,2 three Bian Junyu tower wall 1 of column plate sealing cooperation and positioned at column plate 2 in addition on one side top overflow weir 4, column plate 2 and overflow It flows weir 4 and tower wall 1 cooperates back upper place to form a mass-transfer zone 3, form an overflow ducts 6, overflow weir 4 between overflow weir 4 and tower wall 1 On form through the leakage channel 5 of column plate 2,2 bottom of column plate of 5 lower section of leakage channel, which is equipped with, holds liquid web plate 7, this holds liquid net Plate 7 is used to spread the leakage in leakage channel 5, after leakage is spread on holding liquid web plate 7, can increase the contact surface with meteorological medium Product improves mass transfer effect.

As optional embodiment, 5 top opening height of leakage channel is higher than the apical side height of column plate 2, so set, It can still assemble in mass-transfer zone 3 when liquid phase medium flow is smaller, carry out mass transfer contact with liquid phase medium；

Leakage channel 5 is the stick channel through column plate 2, so set, the percent of pass of leakage can be improved；

It holds liquid web plate 7 to be obliquely installed, and holding 7 angle with horizontal plane of liquid web plate is 20 °, so set, can set by inclination That sets holds liquid web plate 7, increases the movement travel of liquid phase medium；

6 lower ending opening carton of overflow ducts holds the middle part area above of liquid web plate 7, so set, can increase liquid phase medium Holding the movement travel on liquid web plate 7；

It holds liquid web plate 7 to be made of diffuser plate 702 and fixed plate 701, fixed plate 701 is mounted by means of bolts on column plate 2 Immediately below the overflow weir 4 of bottom；

Diffuser plate 702 is stainless steel web plate, so set, can extend the service life of diffuser plate 702.

Using the above structure, it after liquid phase medium from top to bottom enters mass-transfer zone 3, is accumulated inside the mass-transfer zone 3, liquid phase is situated between It when matter liquid level reaches 5 top of leakage channel, is fallen to by the leakage channel 5 and holds liquid web plate 7, held liquid web plate 7 by this and spread Enter subsequent cycle afterwards, after liquid phase medium flow increases to the drain efficiency greater than leakage channel 5, liquid phase medium continues in mass transfer Accumulated inside area 3, until liquid level be more than overflow weir 4, and after fall through overflow ducts 6, carry out next mass transfer circulation, recycle In the process, meteorological medium moves from bottom to top, when by 2 lower section of column plate, and the liquid phase medium contact mass transfer held on liquid web plate 7, It is continued up through overflow ducts 6 to mass-transfer zone 3 after and, carries out contact mass transfer with the liquid phase medium inside the mass-transfer zone 3, with After continue up and carry out next mass transfer circulation；

By opening up leakage channel 5 in column plate 2 and 4 joint of overflow weir, liquid phase can be passed through when liquid phase flow is smaller, and The stroke of the increase liquid phase of liquid web plate 7 is held in cooperation afterwards, to improve the contacting efficiency of liquid phase and gas phase, raising reaches effect；

When liquid phase flow increases, leakage channel 5 cooperates overflow ducts 6 that can expand the spillover efficiency of liquid phase, prevents from blocking.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power Subject to the protection scope that benefit requires.
