Abstract
Vertical sieve tray tower tray in a kind of methanol stripper tower, comprising: column plate, liquid barrier, sieve aperture, downspout; The upper surface of column plate arranges liquid barrier, and sieve aperture is evenly distributed on column plate; Downspout has two kinds of distribution modes on column plate: a kind of center being downspout and being positioned at column plate, and another kind is that downspout is circumferentially arranged near column plate edge; On column plate, two kinds of downspout are distributed in methanol stripper tower and are alternately arranged.In this methanol stripper tower, vertical sieve tray tower tray increases the radial distance of adjacent two layers column plate downspout by two kinds of distributions of downspout, namely adds liquid radial cross-flow time in tower, improves gas-liquid mass transfer efficiency, have higher stability.
Description
Technical field
The utility model relates to technical field of chemical, particularly vertical sieve tray tower tray in a kind of methanol stripper tower.
Background technology
The processing method of methanol process waste water common both at home and abroad at present has: physical treatment process, method of chemical treatment, biological treatment etc.Because methyl alcohol is the strong polar substances of Small molecular, be easy to miscible with water, therefore the physical method such as ion-exchange and charcoal absorption all can not well be removed.Press through the steam stripped method process of vapours during prior art often adopts containing alcohol waste water, so the application of sieve tray is just very extensive.Existing sieve tray, absorbing fluid from overhead stream through each sieve tray time, cannot ensure that absorbing fluid can flow through the various piece of sieve tray fully completely, thus cannot ensure that gas-liquid fully exchanges, productivity ratio is declined.
Utility model content
The purpose of this utility model is, provide a kind of flexible for installation for the deficiencies in the prior art, structure is simple, improves mass-transfer efficiency, vertical sieve tray tower tray in the methanol stripper tower with higher stability.
To achieve these goals, the technical scheme that the utility model adopts is as follows: vertical sieve tray tower tray in a kind of methanol stripper tower, comprising: column plate, liquid barrier, sieve aperture, downspout; The upper surface of column plate arranges liquid barrier, and sieve aperture is evenly distributed on column plate; Downspout has two kinds of distribution modes on column plate: a kind of center being downspout and being positioned at column plate, and another kind is that downspout is circumferentially arranged near column plate edge; On column plate, two kinds of downspout are distributed in methanol stripper tower and are alternately arranged.
Described sieve aperture spacing is equidistantly, and sieve aperture adopts tubaeform.
Described column plate thickness is 2mm.
The beneficial effects of the utility model are, in this methanol stripper tower, vertical sieve tray tower tray increases the radial distance of adjacent two layers column plate downspout by two kinds of distributions of downspout, namely add liquid radial cross-flow time in tower, improve gas-liquid mass transfer efficiency, there is higher stability.
Accompanying drawing explanation
Fig. 1 is vertical sieve tray tower tray scheme of installation in methanol stripper tower.
Fig. 2 is a kind of structural representation of vertical sieve tray tower tray in methanol stripper tower.
Fig. 3 is the another kind of structural representation of vertical sieve tray tower tray in methanol stripper tower.
Above-mentioned number in the figure is described as follows:
1---tower body; 2---column plate; 3---liquid barrier; 4---sieve aperture; 5---downspout; 6---support.
Detailed description of the invention
The technical solution of the utility model is described further by specific embodiment below in conjunction with accompanying drawing.
Vertical sieve tray tower tray in a kind of methanol stripper tower, comprising: column plate 2, liquid barrier 3, sieve aperture 4, downspout 5; The upper surface of column plate 2 arranges liquid barrier 3, and sieve aperture 4 is evenly distributed on column plate 2; Downspout 5 has two kinds of distribution modes on column plate 2: a kind of center being downspout 5 and being positioned at column plate 2, and another kind is that downspout 5 is circumferentially arranged near column plate 2 edge; On column plate 2, two kinds of downspout 5 are distributed in methanol stripper tower and are alternately arranged.Support 6 is welded on the side of tower body 1, and column plate 2 is positioned on support 6.
Carrying out practically process is as follows: gas is arrive above column plate 2 by tubaeform sieve aperture 4 below the column plate 2 of 2mm from thickness, time gas passes through column plate 2, fully carries out gas-liquid exchange with the absorbing fluid being positioned at column plate 2 upper surface.When column plate 2 upper surface absorbing fluid liquid level higher than downspout 5 height time, absorbing fluid is flow on the column plate 2 of lower one deck by downspout 5.Column plate 2 is also provided with liquid barrier 3, the runner that absorbing fluid can be formed by liquid barrier 3 flows through the various piece of column plate 2 simultaneously.Because the downspout 5 between each layer is not on same longitudinal direction, so absorbing fluid fully can both flow through tower tray at every layer, make production efficiency higher.
