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 exist-ing technology and defects of primary condenser core in CS2 mixed water and steam recovery e-quipment are introduced in detail.A new design idea for the primary condenser core is pro-posed.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 pri-mary 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 require-ments 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.
