Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
The utility model relates to a kind of packed tower shape tube liquid and is evenly distributed device, comprises the shape tube that horizontal direction arranges, and the cross section of described shape tube is noncircular cross section; Two planes up and down, two lines or plane and the line of described shape tube are parallel to each other, to guarantee that potential energy equates; Described shape tube is not changing under the prerequisite of vertical height, diminishes gradually along the area of the vertical cross-section of the flow direction shape tube of liquid; The bottom of shape tube is in the first-class identical liquid distribution hole 1, multiple apertures that is arranged at intervals with of same level.
Described liquid distribution hole 1 is horizontally disposed with along liquid flow direction, according to actual conditions, liquid distribution hole 1 can be set to a row, can be also two rows; If be set to two rows' liquid distribution hole, require it for being symmetrical arranged, two rows' liquid distribution hole 1 is in same level.
Further, the vertical cross-section of described shape tube be shaped as upper and lower two planes, two lines or plane and line polygon parallel to each other, below respectively taking the rectangle in Fig. 1-4, triangle, rhombus, be trapezoidally specifically described as example.
The liquid that is respectively shape tube vertical cross-section and is rectangle as shown in A, B, C, D in Fig. 1 is evenly distributed stereogram, right view, top view, the front view of device; The vertical cross-section of shape tube be shaped as rectangle time, its upper and lower two plane keeping parallelisms, along liquid flow path direction, dwindle gradually the sectional area of the vertical cross-section of shape tube by shortening gradually distance between two vertical planes of rectangle, its static energy is remained unchanged, being distributed in same level of liquid distribution hole 1, constant to ensure that drop passes through the flow velocity in liquid distribution hole 1.
As shown in A, B, C, D in Fig. 2, being respectively shape tube vertical cross-section is stereogram, right view, top view, the front view that leg-of-mutton liquid is evenly distributed device; The vertical cross-section of shape tube be shaped as triangle time, the line that it is upper and lower and plane keeping parallelism, by shortening gradually the angle a of two hypotenuses of triangle, the triangle area of shape tube vertical cross-section is dwindled gradually, its static energy is remained unchanged, being distributed in same level of liquid distribution hole 1, constant to ensure that drop passes through the flow velocity in liquid distribution hole 1.
The liquid that is respectively shape tube vertical cross-section and is rhombus as shown in A, B, C, D in Fig. 3 is evenly distributed stereogram, right view, top view, the front view of device; The vertical cross-section of shape tube be shaped as rhombus time, the rhombus of its vertical cross-section must make the line keeping parallelism at upper and lower two ends, keep its vertical height constant, its potential energy is remained unchanged, by changing gradually the relative distance of rhombus both sides hypotenuse, the rhombus area of shape tube vertical cross-section is dwindled gradually, being distributed in same level of liquid distribution hole 1, constant to ensure that drop passes through the flow velocity in liquid distribution hole 1.
As shown in Figure 4, being shaped as when the trapezoidal of vertical cross-section of shape tube, trapezoidal can be both up-narrow and down-wide structure, can be also structure wide at the top and narrow at the bottom, need make upper and lower two plane keeping parallelisms; By changing the relative distance between two trapezoidal sides, the trapezoidal area of shape tube vertical cross-section is dwindled gradually, its static energy is remained unchanged, being distributed in same level of liquid distribution hole 1, constant to ensure that drop passes through the flow velocity in liquid distribution hole 1.
It is pointed out that vertical cross-section in figure is triangle, trapezoidal shape tube, its vertical cross-section can be also del or inverted trapezoidal structure.
Be illustrated in figure 5 the structural representation of the vertical cross-section of another shape tube, described liquid distribution hole 1 is arranged on the bottom of shape tube, it is a row or two rows that liquid distribution hole can be set as required, if be set to two rows, requirement two rows' liquid distribution holes must be in same level, to ensure that its potential energy equates.
