Abstract
The utility model relates to a liquid distributor of a rectifying tower. The liquid distributor comprises a distribution plate, wherein distribution slots are uniformly distributed on the distribution plate. The innovation points of the liquid distributor are as follows: an external fixing ring is arranged outside the distribution plate, and the external fixing ring is connected and fixed with the distribution plate through connecting ribs. Backflow liquid and feed liquid are uniformly distributed to the surface of filling material through the distribution slots on the distribution plate; and furthermore, as the external fixing ring is connected with a tower body of the rectifying tower during mounting, liquid is less prone to flowing to the tower wall to cause wall flow tendency, uniform distribution of the liquid is ensured and mass transfer efficiency is improved.
Description
Technical field
The utility model relates to a kind of rectifying column liquid distribution trough, particularly a kind of rectifying column liquid distribution trough that distributes effective.
Background technology
The rectifying column that adopts in the dichloro-benzenes separation process belongs to packed tower, and it is essential that distributor is installed.Liquid distribution trough places filler upper end, it with phegma with add feed liquid and be distributed to equably on the filling surface, form liquid initial and distribute.Because in the operation of packed tower, the initial distribution of liquid is maximum to the packed tower Effect on Performance, so liquid distribution trough is most important tower internals.
Traditional liquid distribution trough is the distributed in grid device; Be evenly to be covered with distributing slot on the distribution grid; In actual production, find when liquid when packing layer flows downward, have to flow to the tendency that the tower wall forms " wall stream ", the result makes the liquid distribution inequality; Reduce mass-transfer efficiency, make the filler at tower center can not be wetted when serious.
Summary of the invention
The technical problem that the utility model will solve provides a kind of rectifying column liquid distribution trough that distributes effective.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of rectifying column liquid distribution trough; Comprise distribution grid; Evenly be covered with distributing slot on the said distribution grid, its innovative point is: said distribution grid is provided with an outer retainer ring outward, and said outer retainer ring is connected fixing with distribution grid through dowel.
The advantage of the utility model is: phegma with add the distributing slot of feed liquid through distribution grid and be evenly distributed to filling surface; And owing to be connected with the tower body of rectifying column by outer retainer ring when installing; Be not prone to the mobile tendency that causes " wall stream " of Xiang Tabi; The assurance liquid distribution is even, improves mass-transfer efficiency.
Description of drawings
Accompanying drawing 1 is the utility model rectifying column liquid distribution trough structural representation.
The specific embodiment
Shown in accompanying drawing, comprise distribution grid 1, distributing slot 2, outer retainer ring 3, dowel 4, evenly be covered with distributing slot 2 on the above-mentioned circular distribution plate 1, outside distribution grid 1, be provided with retainer ring 3 outside, outer retainer ring 3 is connected fixing with distribution grid 1 through dowel.
Be connected with the tower body of rectifying column by outer retainer ring 3 during installation, be not prone to the mobile tendency that causes " wall stream " of Xiang Tabi, guarantee that liquid distribution is even, improve mass-transfer efficiency.
Claims (1)
1. a rectifying column liquid distribution trough comprises distribution grid, evenly is covered with distributing slot on the said distribution grid, it is characterized in that: said distribution grid is provided with an outer retainer ring outward, and said outer retainer ring is connected fixing with distribution grid through dowel.
