n.泄水管(下導(dǎo)管)

Based on this,the effect of downcomer diameter and h... 所獲得的結(jié)果對(duì)氣升式反應(yīng)器的設(shè)計(jì)優(yōu)化具有指導(dǎo)意義。

The gas holdups both in the riser and the downcomer slightly decreased with an increase in superficial liquid velocity. 各級(jí)內(nèi)上升管和下降管的氣含率均隨表觀液速的增大而減小，但影響程度較小。

Structure and operating performance of new fixed valve tray with suspending downcomer (DJ - 5 tray) was introduced. 新型固定閥懸掛降液管塔板是一種新型大通量高效DJ塔板。

DOWNCOMER BACKUP FLOOD： Downcomer is totally full of froth; liquid backs up on tray. 降液管液泛：降液管被完全充滿，液相回流到塔盤(pán)。

Based on the advancement of the downcomer,some opinions of the downcomer research were presented. 針對(duì)當(dāng)前板式塔降液管研究的進(jìn)展情況,提出了一些關(guān)于降液管研究方向的看法。
