[structure and characteristics]
Liuleng tube type falling film absorber has the characteristics of high absorption efficiency, high absorption intensity (generally up to 0.8 ~ 1.20 T / single tube, daily), high acid concentration, low outlet temperature, no need for cooling, stable operation and convenient control. This product is divided into type I and type II. Type I lower head is impregnated graphite and type II head is steel lined rubber part. When the order is not marked, it is supplied by type.
Design temperature: tube side: inlet temperature < 170 ° C
Shell side: - 20 ° C ~ 60 ° C
Allowable pressure: tube side: < 0.1MPa
Shell side: 0.3MPa
Heat exchange area: 3 ~ 120m2, large tubular falling film absorber can be designed and manufactured according to the needs of users.
This equipment does not pollute the product. It is mainly used to absorb HCI > gas to produce hydrochloric acid. It can also be used for membrane absorption of other gases (SO2, NH3, P2O5, H2S, etc.).
(1) The absorption efficiency is high;
(2) The pressure drop in the absorption system is low;
(3) The temperature of acid produced is low, generally 3 ~ 15 ° C higher than that of cooling water, so there is no need for post cooling and the production process is simplified;
(4) High heat transfer efficiency, corrosion resistance and long service life.
