With noble gases to CS2And H2S carry out substep be desorbed, deposit the operation that is in operation, adjustment more numerous and diverse, the degree that recycles is little, transport
The defects such as row expense height；
Three, condensation：Containing CS2The higher waste gas of concentration is through over-heat-exchanger（Condenser）, with water at low temperature directly or indirectly by waste gas
Temperature is down to CS2Below boiling point, with recovering liquid CS2, such as patent documentation CN1016599B（Anti- during carbon disulphide production
Answer the method for separating and processing of product, 1990.06.13）Record, in pressure for 1.5-10 kg/cm and temperature be-
Under the conditions of 10-+20 DEG C, Carbon bisulfide is once made all to liquefy and complete the separation process with hydrogen sulfide.But it is proven, should
Method for viscose staple fibre spinning process tow solidification, decompose when discharge little tolerance, high-temperature, high concentration CS2Return
Time receiving, CS2Efficiency the most obvious.
Understood based on above-mentioned situation, existing viscose rayon produce waste gas processing method also exist treatment effect undesirable,
The problems such as production cost is high, particularly condensation reclaim CS2Method in it is desirable to high concentration CS2Recovery when its efficiency the brightest
