Abstract
A tank-tank type liquid distributor for uniformly distributing the liquid on the cross-section of filler tower to play the full role of filler is composed of 1-3 class-one tanks, 2-15 class-two tanks under said class-one tanks, liquid guiding tanks between class-one and class-two tanks, liquid guiding plates, buffer plates, silk screens and fastening plates.
Description
Technical field
The present invention relates to a kind of liquid distribution trough, belong to the cloth liquid element of the filler that heat transfer, mass transfer use, mainly is to be used in the packed tower liquid being uniformly distributed in whole tower section.
Background technology
The mass transfer apparatus that in industrial production such as chemical industry, oil, light industry, metallurgy, uses, mainly contain packed tower and plate column two big classes, in packed tower, liquid distribution trough is a critical elements, and it is that the liquid that will enter packed tower is uniformly distributed in the tower section, make liquid uniformly with uprising gas or another liquid even contact mutually, avoid bad distribution phenomenons such as channel, bring into play the separative efficiency of packed tower further, improve two chances that contact, guarantee that packed tower is working properly, stable.
Summary of the invention
The present invention proposes a kind of trough-trough type liquid distributor, this liquid distribution trough has improved the be evenly distributed degree of liquid in packed tower, make liquid on whole tower section, to be evenly distributed, improve dropping liq and uprising gas or another contact uniformity coefficient of liquid mutually that rises, improve the mass transfer separative efficiency of packed tower.
Main technical schemes: primary structure trough-trough type liquid distributor of the present invention, form by one-level groove, secondary groove, intake chute, draining plate, buffer board and buffering silk screen, clamp etc., one-level groove, secondary groove all are slot type structures of being made by metal or plastics, the one-level groove is positioned over above the secondary groove by intake chute, as shown in Figure 1 (Fig. 1 is the structure diagram of secondary tank type liquid distributor).Normally 1-3 of one-level groove, secondary groove quantity are different and different along with tower diameter, can be 2-15, and the one-level groove is a groove usually, and the secondary groove is a 3-10 composition.
The size of groove: one-level groove height is 100-400mm usually, and secondary groove height also is 100-400mm, and its width is: the one-level well width is 100-800mm usually, and secondary groove height is 20-200mm.The length of one-level groove and secondary groove changes with tower diameter.Usually and the chord length of the circle of its position approaching.
On the sidewall of intake chute, offer several apertures, can be so that liquid be distributed in each secondary groove by each aperture, because aperture is driveed in the side, be unlikely to be lowered by the solid particle and the suspension that contain in the liquid like this and stop up, prolong operation cycle guarantees that operation is normal stable.
In the side of secondary groove, have aperture and be used to the liquid that distributes, its operation principle is, by the aperture of secondary groove side, equably with liquid distribution on fixing liquid distribution point.Each distributed points has 2 perforates up and down, and wherein Shang Mian that Kong Yaoda's is many, can guarantee that fluid flow greatly also can flow out it more fully fully from that top hole, and be unlikely to overflow from the secondary groove.Each distribution hole of secondary groove all is to drive in the side, like this, can avoid the small amount of precipitate thing that contains in the liquid or suspension to stop up aperture equally, causes skewness or influence the phenomenon generation of operate as normal.
Side at secondary groove distribution aperture also is provided with draining plate, and draining plate is made the angle steel structure, point is welded in the side of secondary groove, and the liquid that it will gush out from the distribution aperture of secondary groove blocks and makes it avoid flowing down along angle steel, reach the effect that liquid side distributes, improve the degree that is evenly distributed.
Effect of the present invention: because the trough-trough type liquid distributor that each one-level groove and secondary groove are formed, intake chute places the one-level groove, the aperture of on the sidewall of intake chute, offering, with liquid by being uniformly distributed in each secondary groove, because aperture is driveed in the side, be unlikely to be lowered by the solid particle and the suspension that contain in the liquid like this and stop up.Buffer board on the one-level groove and silk screen can suitably cushion the kinetic energy that liquid descends, and avoid liquid distribution trough is washed out.
The distribution aperture of opening in secondary groove side, uniformly with liquid distribution on fixing liquid distribution point.Each distribution hole of secondary groove can avoid the small amount of precipitate thing that contains in the liquid or suspension to stop up aperture equally, causes skewness or influence the phenomenon generation of operate as normal.
The draining plate that is provided with in the side of secondary groove distribution aperture, the liquid that will gush out from the distribution aperture of secondary groove blocks and makes it avoid flowing down along angle steel, reaches the effect that liquid side distributes, and improves the degree that is evenly distributed.

The specific embodiment
Embodiment 1: as shown in Figure 1, one embodiment of the present invention are to make trough-trough type liquid distributor, and the width of one-level groove is 250mm, and the width of secondary groove is 200mm, and it highly is 295mm.The distribution hole diameter is 3.5mm.Be used for the material filling type rectifying column that methyl acetate separates with methanol rectification, reached the equally distributed effect of liquid.Increased the gas-liquid mass transfer chance, thereby made the separative efficiency of filler higher.Make material be able to abundant separation like this, promptly improved product purity, reduced overhead product content and consumption of raw materials in the raffinate, reduced reflux ratio, saved energy and improved production capacity.
Claims (6)
1, a kind of trough-trough type liquid distributor is made up of one-level groove, secondary groove, intake chute, draining plate, clamp etc., and one-level groove, secondary groove all are slot type structures of being made by metal or plastics, and the one-level groove is positioned over above the secondary groove by intake chute.
