Background technology
Tower tray is one of critical piece of plate column, and be the parts realizing the heat transfer of work liquid, mass transfer in plate column, tower tray is made up of column plate, downspout and downflow weir etc. usually.When gas from bottom to top, liquid from top to bottom carry out contact mass transfer time, fully contact for making gas-liquid, improve its contact surface, increase mass transfer effect, be typically employed in vertical tower and install polylith tower tray, gas-liquid separation again after fully contacting in tower tray, carries out mass transfer separation again in next block tower tray, so repeatedly act on, reach the mass-and heat-transfer of vapour-liquid energy maximal efficiency.There is the defect of configuration aspects in existing tower tray, also there is vapour-liquid mass performance not high in heat transfer and mass transfer, and treating capacity is little, simultaneously the susceptible to plugging problem of tower tray when material is messy.
Based on this, special proposition the utility model.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of rectifying column tower tray, comprise fluid inlet district, vapour-liquid mixing mass-transfer zone and liquid discharge mouth region, be provided with arc import foam in fluid inlet district and promote weir, promote that edge, weir is provided with draining plate at arc import foam; Be covered with in vapour-liquid mixing mass-transfer zone and have many perforate standing valves; Downflow weir after liquid-phase outlet district is provided with and is folded to and downspout.
Further, described perforate standing valve be vapour-liquid mixing mass-transfer zone in tabular projection, perforate standing valve comprises front rake part, intermediate valve top portion and rear portion sloping portion, described front rake part relative to rear portion sloping portion closer to fluid inlet district.
Further, the width of described front rake part is greater than the width of described rear portion sloping portion.
Further, described downflow weir is multistage flanging.The benefit of such setting is to allow flowing fluid ratio flow into downspout more equably.
Further, in the middle part of described downspout, be provided with holder liquid platform, for the liquid that support flows down from downflow weir, the bubbling area that formation one is extra on next tower tray simultaneously.
The beneficial effects of the utility model: 1, adopt solid valve design, have high disposal ability, mechanical is worn and torn, and has outstanding anti-clogging; 2, adopt the downflow weir of multistage flanging, improve liquid phase disposal ability; 3, holder liquid platform is set in the middle part of downspout, is conducive to bubbling area area and maximizes.

Detailed description of the invention
Below with reference to the accompanying drawings, the utility model is described further.
As shown in Figure 1, a kind of rectifying column tower tray of the utility model, comprise fluid inlet district 1, vapour-liquid mixing mass-transfer zone 2 and liquid-phase outlet district 3, be provided with arc import foam in fluid inlet district 1 and promote weir 4, promote that edge, weir 4 is provided with draining plate 5 at arc import foam; Multiple perforate standing valve 6 is provided with in vapour-liquid mixing mass-transfer zone 2; Liquid-phase outlet district 3 is provided with downflow weir 7 and downspout 8.
As shown in Figure 2, described perforate standing valve 6 is the tabular projection in vapour-liquid mixing mass-transfer zone 2, perforate standing valve 6 comprises front rake part 61, intermediate valve top portion 62 and rear portion sloping portion 63, described front rake part 61 relative to rear portion sloping portion 63 closer to liquid-inlet district 1.
As shown in Figure 3, the valve top width end width D 2 of described front rake part 61 is greater than the narrow end width D 3 in valve top of described rear portion sloping portion 63, and the wide end width Z2 of front rake part 61 is greater than the narrow end width Z6 of described rear portion sloping portion 63.
In order to allow flowing fluid ratio flow into more equably in downspout 8, downflow weir 7 is set to multistage flanging.In one embodiment, downflow weir 7 is five sections of flangings, and that section of limit is wherein the longest, and the length of other 4 flangings is equal (as shown in Figure 1).
The middle part of downspout 8 is provided with holder liquid platform 9, and for the liquid that support flows down from downflow weir 7, simultaneously because holder liquid platform 9 is protrusion, the space formed bottom it can form an extra bubbling area (as shown in Figure 1) on next tower tray.
As shown in Figure 3 and Figure 4, the size at each position of perforated valve 6 has strict relation in concrete application process, aperture area Z5 and the thickness of slab AST of its lift of a valve PFD, line space PRS, interlamellar spacing PTS, valve top length D1, valve top width end width D 2, valve top narrow end width D 3, vertical corner D4, horizontal corner D5, valve base length Z1, wide end width Z2, lengthwise centers position Z3, widthwise central Z4 position, each valve need to set according to table 1, table 2 and table 3, in addition, table 4 lists the parameter of several typical perforated valve 6.
