1、液環式真空(kong)泵(beng)抽負(fu)系統軟件步(bu)驟
液環式真空泵系統軟件步驟平面圖,液氯包裝所造成的廢氯氣(關鍵由氯氣和空氣組成)進到到類似真空罐的,由液環式真空泵以98%(wt)硫酸為物質開展循環系統吸脂,保持類似真空罐的在30~40kPa的真空值,保證液氯充裝氣瓶實際操作順利開展。從液環式真空泵出去的汽液化合物(關鍵由氯氣+氣體+硫酸構成)進到到氣液分離器開展汽液分離出來,從分離設備出去的廢氯氣進到到氯氣脫硫塔,以濃度值為18%(wt)上下NaOH水溶液消化吸收氯氣,不凝氣體(氣體)由離心風機抽離出來排盡。從分離設備出的硫酸因經液環泵縮小后溫度會上升,需挪走發熱量,硫酸歷經螺旋式板式冷卻器以循環系統冷卻循環水制冷后再進到到真空泵進口,持續循環系統吸脂液氯包裝造成的廢氯氣。液氯包裝時廢氯氣中滲入的空氣中帶有水份,非常是南方天氣,空氣水份量大,水份隨空燃比和硫酸觸碰后被硫酸消化吸收,導致硫酸變稀,因此要按時排污和拆換硫酸,避免機器設備被浸蝕。當鹽酸濃度值降至92%(wt)時,就需要從上位槽添加98%(wt)硫酸開展換置。
