Abstract
The utility model relates to a column plate with a bubble promoting device, which comprises a liquid lowering pipe, a float valve and a bubble promoting device, wherein the float valve is arranged on the column plate and the bubble promoting device is arranged on the upper layer of the column plate below the outlet of the liquid lowering pipe. The bubble promoting device is hollow, the bottom edge of the bubble promoting device is spot-welded with the column plate or inserted into a hole of the column plate. The tower tray has the advantages of thin liquid layer on the hole and small pressure head because the position of the bubble hole is higher than that of the column plate, and easy gas pass and liquid leak prevention because the hole side is provided with a liquid negative pressure zone. Thereby, good bubbles are formed, gas and liquid contacting mass transfer is promoted, liquid level on a liquid meeting side is raised, liquid sealing on the outlet of the liquid lowering pipe is formed and the gas is prevented from passing through the liquid lowering pipe.
Description
The utility model relates to a kind of column plate that has the bubbling promoters, is the gas-liquid contact mass transfer equipment in oil refining, the petrochemical industry, also is the important component part of rectifying in this field (or absorption) column plate.
Traditional rectifiying plate is made up of downspout, seal pot, float valve (or sieve plate) mass-transfer zone etc., and liquid enters the float valve mass-transfer zone by downspout through seal pot.Seal pot is to establish for bearing the liquid that flows out in the downspout, does not establish mass transfer components such as float valve on the seal pot, thereby does not carry out mass transfer, it is the inactive area of column plate, and when liquid enters the column plate mass-transfer zone by seal pot, thick because of liquid layer, static pressure is high, easily leakage takes place and bubbling is inhomogeneous.The liquid that flows out in the downspout has certain pressure and speed, so float valve or sieve aperture are set on traditional seal pot, a large amount of leakages takes place then, has a strong impact on plate efficiency.
The purpose of this utility model is a kind of column plate that has the bubbling promoters of design, utilize traditional seal pot area, special member is set, making has the hydraulic fluid physical efficiency very fast by gas institute bubbling in the downspout, thereby form additional mass transfer area and gas channel, to improve the permissible load (production capacity) and the plate efficiency of column plate.
The column plate that has the bubbling promoters of the utility model design, this column plate comprises downspout, float valve and bubbling promoters, float valve is arranged on the column plate, the bubbling promoters is arranged on the column plate, be positioned at the oblique below of upper strata downcomer outlet port, the bubbling promoters is a hollow shape, and top has the bubbling hole, base and column plate spot welding, or insert in the hole of column plate.
Bubbling promoters in the utility model can have several forms, and first kind is pyramid, has the bubbling hole on pyramidal three adjacent inclined-planes, and the another side that does not have the bubbling hole is for meeting liquid level.Second kind is ridge shape, has the bubbling hole on a rectangle face of ridge and two gores, and the another side that does not have the bubbling hole is for meeting liquid level.The third is a ridge shape, has the bubbling hole on two rectangle faces of ridge and a gore, and the another side that does not have the bubbling hole is for meeting liquid level.The 4th kind is tubular, has the bubbling hole on 2/3 lateral area of tube, and other three/one side is for meeting liquid level.Above-mentioned bubbling hole can be strip, circle or fin shape.
The utility model has the advantages that: because the position in bubbling hole is higher than column plate, liquid layer above the hole is thin, and pressure head is little, and the perforate side is the negative pressuren zone of liquid, so gas be easy to by, avoid leakage, thereby form good bubbling, promote the gas-liquid contact mass transfer, simultaneously, owing to the liquid level of liquid-facing side has been raised in the existence of bubbling promoters, caused the positive fluid-tight of downcomer outlet port, avoid gas to pass from downspout.
Fig. 1 is the structural representation of traditional column plate.
Fig. 2 is the position of bubbling promoters on column plate and effect schematic diagram.
Fig. 3 is pyramid (rectangular pyramid shape) bubbling promoters.
Fig. 4,5 is a ridge shape bubbling promoters.
Fig. 6 is the bubbling promoters of circular (oval, oval).
Fig. 7 is the bubbling promoters of band wing and leg.
Among Fig. 1-Fig. 7, the 1st, downspout, the 2nd, column plate, the 3rd, float valve, the 4th, seal pot, the 5th, bubbling promoters, the 6th, float valve, the 7th, wall-attaching type downspout, the 8th, positive fluid-tight, the 9th, valve opening, the 10th, the bubbling hole, the 11st, the fin in formation bubbling hole, the 12nd, bubbler inserts the leg in the valve opening.A among the figure is to for meeting liquid level.
Describe content of the present utility model in detail below in conjunction with accompanying drawing.
The bubbling promoters is made with 1～3mm metallic plate, by its expanded view blanking, punching, punching have two kinds multi-form, one for washing out metallic plate circular hole or the slotted hole that the back forms, another kind is the wing hole that metallic plate is washed into definite shape, part that to be metallic plate dashed is had the end (see figure 7) that links to each other with the metallic plate body, and fin covers the top in hole, then this orifice plate is intervolved into pyramid.There are two kinds of forms on the base of bubbling promoters, and a kind of is flat, the bubbling promoters of this form with spot-welded on column plate; Another kind of form is to have four pin on the base, and these four pin can insert the float valve hole, then with the pin half-twist, and can be on column plate with the fastening of bubbling promoters.
The bubbling promoters of the utility model design is met liquid level bears the liquid that flows out in downspout fierce impact when operation, be zone of positive pressure so meet liquid level, and liquid level raises, and can prevent that gas from sealing in downspout.Non-liquid-facing side is a negative pressuren zone, and this place is opened the bubbling duct and easily is the air communication mistake of column plate below, and passes through liquid layer and form bubble level or froth bed preferably, thereby gas-liquid mass transfer takes place, and improves separative efficiency.
