產品詳細介紹:

設備技術性能:

1.溫度:本設備可適用的溫度范圍是-10~125°C。為提高吸收效率,應盡量降低吸收劑溫度。

2.壓力:殼程和管程均應≤0.3MPa(表)。

3.真空度:殼程和管程應≤-0.1MPa柱。

4.降膜吸收器吸收劑用量:根據HCI濃度而定,一般10-20m3/h(10m2吸收器)。

5.降溫水用量可根據操作工藝條件進行熱量衡算而定,增加降溫用量,用利提高吸收效率。

適用范圍:

可用于合成氯化氫和回收氯化氣體吸收,也可用于H2、S、SO2、NH3等氣體的吸收,得到的產品濃度比絕熱吸收高5%。采用二級串聯,循環吸收,效率可達98%以上。吸收能力:吸收器的生產能力可以在較大范圍內進行調整,控制方便。例如二臺10m2膜式吸收器串聯使用,一天可獲得31%鹽酸10~20噸。

操作:

吸收劑與被吸收的氣體可逆流操作,也可并流操作。逆流操作時上升的流體將導致液膜流速降低,一般當氣體流速在管內5~10m/s時出現流泛現象。降膜吸收器并流操作時氣體由上而下流動,將會使液膜厚度減簿,液膜流速增加,在氣體流速相同的情況下,凍時的流體阻力比逆流時小得多。并流時氣速可高達15~30m/s,但吸收推動力比逆流時小,目前生產中大多采用并流操作。
