  Abstract:In order to improve the recovery amount of CS₂ during the production of regenerated viscose fiber and eliminate the hidden dangers of environmental protection and safety，the existing technology and defects of primary condenser core in CS₂ mixed water and steam recovery equipment are introduced in detail.A new design idea for the primary condenser core is proposed.The parameters such as hole distance，space between boreholes，opening hole rate of screen plate，and opening hole area are designed and calculated.The results show that the primary condenser core is modified into screen plate basket type，which can increase the contact area between steam containing CS₂ and condensed water，and meet the pressure drop requirements of the system，with low noise and convenient installation.After modification，the amount of every ton of the viscose staple and filament of CS₂ recovery amount can be increased by 0.5 kg，which effectively reduces the load of the dynamic adsorption system，improves the adsorption recovery effect，and reduces the emission of harmful gases.
Key Words:regenerated viscose fiber；condenser；CS₂；recovery amount；core；deflector；screen plate
