Abstract
The utility model relates to a composite sloping hole valve tray, which belongs to the field of chemical equipment. The composite sloping hole valve tray is composed of fixed inclined holes and floating inclined holes. An array of middle floating inclined holes are arranged every interval of 400 mm, and one edge guiding floating inclined hole is arranged at the edge of the tray every interval of one array of the floating inclined holes, and the rest are fixed inclined hole. The cover plate of the floating inclined holes is floated and arranged on the vent hole of the tray, the opening degree of the floating inclined holes can be automatically adjusted along with the change of the air speed in a tower, and consequently, the aperture ratio of the tray can be automatically adjusted. The tray is assured to have good operation performance within the wider range of the air speed.
Description
The utility model relates to tower plate structure, and particularly complex slant-hole tray belongs to the chemical industry equipment field.
Slant-hole tray commonly used is a kind of high capacity tray in chemical industry at present, and its advantage is that flux is big, resistance is little, efficient is high, cost is low, so obtained using widely.But it is smaller that its shortcoming is an operating flexibility, leakage easily under low vapour speed.
It is bigger that the purpose of this utility model provides a kind of operating flexibility, can be used for the column plate of the operating mode that steam flow speed is lower in the tower.
The utility model complex slant-hole tray is by fixedly the inclined hole and the inclined hole that floats are formed.The inclined hole that floats in the middle of one row is set every about 400mm, every the fixing inclined hole of a row, in column plate edge the unsteady inclined hole of an edge guiding is set, to improve liquid flow condition; All the other are fixing inclined hole.The cover plate of unsteady inclined hole floats and rests on the logical steam vent of column plate, can open and close by the speed of the vapour in tower size, with the circulation of adjusting gas, reach the assurance column plate and keep good operating characteristics in the vapour speed scope of broad.
Fig. 1 is the utility model complex slant-hole tray plate face layout drawing.
Fig. 2 is fixing inclined hole structure chart.
Fig. 3 is the inclined hole structure chart that floats.
Accompanying drawings embodiment is as follows:
Complex slant-hole tray floor plan when Fig. 1 is single overflow, wherein 1 is downspout, and 2 is downflow weir, and 3 are fixing inclined hole, and 4 are the edge guiding inclined hole that floats, and 5 is the unsteady inclined hole in centre, and 6 is seal pot.Edge guiding floats inclined hole generally every the fixing inclined hole of a row, is provided with one at the column plate edge.The middle inclined hole that floats is provided with a row according to the column plate diameter every about 400mm.Fixedly the structure of inclined hole is seen Fig. 2.The structure of unsteady inclined hole is seen Fig. 3.Cover plate (7) is floating to be rested on the logical steam vent of column plate (8).When vapour speed was higher in the tower, cover plate (7) can open, and increases open ratio of plate.When vapour speed was low in the tower, cover plate (7) can be closed, and reduces percent opening.The maximum open degree of cover plate (7) is controlled by positive stop hook (9).
The utility model complex slant-hole tray owing to be provided with unsteady inclined hole, so can adjust the percent opening of column plate automatically along with the variation of vapour speed in the tower, guarantees that column plate has good operating characteristics in the vapour speed scope of broad.The unsteady inclined hole of guiding can improve the interior liquid of tower to flow condition, reduces backmixing of liquid phase, improves the mass transfer effect between vapour, liquid phase.This column plate flux is big, efficient is high, resistance is little, operating flexibility is good.
Claims (2)
1, a kind of complex slant-hole tray is characterized in that being made up of the fixing inclined hole and the inclined hole that floats, and the inclined hole that floats in the middle of the row is set every about 400mm, every the fixing inclined hole of a row, in column plate edge the unsteady inclined hole of an edge guiding is set, and all the other are fixing inclined hole.
2,, it is characterized in that floating the resting on the logical steam vent of column plate of cover plate of inclined hole of floating, and positive stop hook restriction opening degree is arranged according to the said complex slant-hole tray of claim 1.
