Abstract
The utility model discloses a floating valve-tongue hole composite tray of a rectification column. The composite tray consists of a column plate, floating valves, an inlet weir and a down-flow pipe. The composite tray is characterized in that a row of tongue holes are arranged between every two adjacent floating valves, a tongue piece is arranged on each tongue hole, each row of tongue pieces are in the same direction, and two adjacent rows of tongue pieces are in the opposite directions. Through the floating valve-tongue hole composite tray of the rectification column, the aperture ratio of the column plate is enlarged, and the velocity of valve holes is reduced; and by lateral ejection of the tongue holes, the upper liquid layer of the tray is uniform, the height of a foam layer is reduced, and foam entrainment is reduced, so that the upper limit load of the tray is improved.
Description
Technical field
The utility model belongs to the equipment of distillation, absorption process in oil, the chemical industry, relates in particular to the compound tower tray in a kind of rectifying column float valve one tongue hole.
Background technology
In industry such as oil refining, petrochemical industry, chemistry, tower tray is the visual plant of separating mixture, and the output of its product, quality, energy consumption, cost etc. are played an important role.At present, the tower tray of conventional use exist gas under the circular valve block in horizontal direction to around spray.The air-flow of adjacent each valve ejection liquidates mutually, has aggravated entrainment, has brought radially back-mixing of liquid phase, and the arc area on this external column plate forms and refluxes and stagnant areas, has therefore satisfied not the needs in producing.
Summary of the invention
The purpose of the utility model is intended to the deficiency that exists in the background technology, and the compound tower tray in rectifying column float valve one tongue hole that provides.
The compound tower tray in rectifying column float valve one tongue hole of the utility model; Be to constitute, it is characterized in that being provided with row's tongue hole between every adjacent two row's float valves that the tongue hole is provided with tongue piece by column plate, float valve, inlet weir and downspout; The direction of every row's tongue piece is identical, and two adjacent row's tongue pieces is in the opposite direction.
The compound tower tray in rectifying column float valve one tongue hole of the utility model has enlarged open ratio of plate, has reduced valve opening speed; The side direction in tongue hole is sprayed, and makes that liquid layer is tending towards evenly on the tower tray, has reduced bubble steamed bun layer height; Reduce entrainment, thereby improved the last limited load of tower tray.
Description of drawings
Fig. 1 is the planar structure sketch map of the compound tower tray in rectifying column float valve one tongue hole of the utility model.
The specific embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing:
The compound tower tray in rectifying column float valve one tongue hole of the utility model; Be to constitute by column plate 1, float valve 2, inlet weir 3 and downspout 4; It is characterized in that being provided with row's tongue hole 5 between every adjacent two row's float valves 2; The tongue hole is provided with tongue piece 6, and the direction of every row's tongue piece 6 is identical, and two adjacent row's tongue pieces 6 is in the opposite direction.
Liquid flows into liquid receiving area 7, flows into bubbling area 8 through inlet weir 3, and first row is float valve 2 in the bubbling area 8; Second row is tongue hole 5 for tongue hole 5, the three rows for float valve 2, the four rows; By that analogy; Do not point to the guidance quality of downspout 4 directions like float valve 2, then can in bubbling area 8, arrange the plurality of rows otch 9 identical, to overcome the gradient of liquid level on the column plate and to lower foam height with the flow direction.
