【文章內(nèi)容簡(jiǎn)介】 more than 90% of, pouring down areas are generally played 10% of the mass transfer. 3 DJ type posite plate DJ type structural characteristics of the posite plate DJ tray is a multidowner trays, depending on the size of the liquid load, you can set one or more root rectangular downer. Downer arranged trays middle, downers of adjacent trays each other into a 90 176。 arrangement. Around the downer overflow periphery. Overflow weir than the average plate 25 times as long. Downer suspension in the gas space. By the liquid area openings bubbling. By the liquid zone outside of the DJ tray is also equipped with a spoiler, in order to improve the flow patterns of liquid, the liquid residence time distribution is more uniform. Set in the DJ tray of liquid antishock device leakage, reducing the shortcircuit caused by the impact of leakage. Figure 5 shows the basic structure of the DJ tray. Figure 6 is a preassembled photos of the DJ tray. 內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)英文翻譯 5 穿流復(fù)合塔板效率曲線(xiàn) DJ 型塔板的結(jié)構(gòu) DJ 型塔板照片 內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)英文翻譯 6 Air posite filler technology used in the DJ tray, constitute a posite plate shown in Figure 7 DJ 1 (also known as DJ3 trays). Complex homes to fill defense packed in specially designed packing basketpull Xuan fixed in the tray below, fill baskets and trays to leave some space. liquid are all basically from the downer overflow posite fillings from the inhibition of the fog Zhu entrainment and improve the role of gas distribution.

By optimizing the area of the closure panel opening, it is necessary to ensure that the liquid unimpeded. Reduce the flow resistance. But also to ensure that the liquid seal does not brag gas. Difficulties of this, more than one downer selfstyled line in Figure 7. Normal operating area in the right of selfstyled line. Lower limit ignorant of the leakage line, there are a selfstyled line of operation. Operation of lower resistance leakage line and selfstyled line, whichever is Operating capandplate is no different, but also the downer flooding lines and excessive entrainment line. Because posite fillings inhibit entrainment, Figure 8, the excessive entrainment line is much higher than the downer flooding line. The upper control limit of the tray downer flooding line. DJ type posite plate with highthroughput characteristics of the general welltype tower Ying and air posite fillings bring greater efficiency and greater operational flexibility. Figure 9 shows a fog soo entrainment pared with and without posite fillings. Figure 10 shows the measured for ethanol, a water system in the heat mold device 300 without pound filler tray efficiency parison. See Figure cho. Composite fillings can greatly reduce the amount of entrainment can improve the tray efficiency of 10% to 15%. Can also see the figure, a particularly hi
