Abstract
The invention provides a large composite flow-through tray. According to the invention, a staggered flow-through sieve plate with a porosity same with that of a high-porosity flow-through tray is fixed on the upper part of the high-porosity flow-through tray. Integrally, blocked mounting is carried out according to an H-shaped vertical edge. The H-shaped vertical edge serves as a self supporting beam of the composite flow-through tray. A perpendicular separation plate is arranged on an upper groove. With the H-shaped vertical edge and the separation plate, the entire tray is divided into a plurality of mixing tanks, such that pressure drop can be reduced, gas-liquid contact area and time can be increased, and throughput and operation flexibility can be greatly improved. Gas bubble breaking and thinning, and interface updating enhancing functions are provided among trays, such that the efficiency of the composite flow-through tray is greatly improved. Tray ultra-large supporting rings, strict requirements on mounting levelness, and an amplification effect are eliminated. A tray ultra-large supporting structure difficulty and a tray strength problem are solved. Therefore, tower upsizing can be easily realized.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As mentioned above, middle compound dual-flow tray is that cross section is the structure (these dual-flow tray 1 two ends are fixed by the bracing ring of whole circle on connector 7 and outer wall) of H shape, and the compound dual-flow tray piecemeal that both sides outermost is connected with outer wall, H shape vertical edge 3 is no longer established in outside, only by inner side H shape vertical edge 3 and fixed leg 5, complete fixing, the structure that the compound dual-flow tray cross section in outside is T shape, dual-flow tray 1 is wherein fixed by the bracing ring of whole circle on connector 7 and outer wall, fastener in the standard tower that connector 7 is existing column plate, just in this case, it is smaller that the outer rim of the dual-flow tray 2 on top is compared dual-flow tray 1, so that assembly and connection part 7.Certainly also can be made as by dual-flow tray 2 and connect bracing ring and connector 7.
The compound dual-flow tray of the efficient high operating flexibility high flux anti-blocking of ultra-large type provided by the present invention has the following advantages: (1) large aperture is conducive to anti-obstruction, and high opening rate has significantly reduced plate pressure drop, suitable with the filler pressure drop of the height equivalent to one theoretical plate (HETP).(2) double-deck wrong row's plate has increased gas-liquid contact area and time, vapour-liquid contact mixing intensity improves greatly, interface is upgraded probability and is greatly strengthened, the contact of falling ship shape when especially vapour-liquid is through column plate, improved significantly the mass transfer separative efficiency of compound dual-flow tray, compare with common dual-flow tray, point efficiency has improved 30%.(3) double-deck wrong row's plate has expanded the gas-liquid load interval that forms froth bed, efficient operation district void tower kinetic energy factor 0.3-8(m/s) .(kg/m3)
