科冪反應釜主動(dòng)降低釜內的溫度的形式有哪些？各自的優(yōu)缺點(diǎn)是什么？

目前主要有風(fēng)冷、內冷卻以及循環(huán)油冷三種。

風(fēng)冷就是將科冪反應釜放置于通風(fēng)處，通過(guò)風(fēng)帶走熱量，從而達到冷卻效果，這種方式最簡(jiǎn)單易行，但冷卻速率較慢，且受當地條件影響。

內冷卻目前主要是增加內冷卻盤(pán)管，通過(guò)冷卻液帶走釜內熱量，達到冷卻效果，這種方式降溫速率較快，但是容積較小的反應釜由于釜內空間限制，無(wú)法安裝，而且在釜內溫度較高時(shí)（≥400℃）普通冷卻液難以起到降溫作用。

循環(huán)油冷主要是通過(guò)循環(huán)油浴系統來(lái)實(shí)現降溫，通過(guò)油泵不斷將冷油泵至釜外夾套循環(huán)降溫。這種方式降溫比較穩定，但目前只有循環(huán)油浴加熱反應釜才有此配置。
