针对含氯化聚合物的废旧塑料，研制了双螺杆脱氯机及脱氯工艺。介绍了双螺杆挤出机的概况.本文介绍了脱氯机和脱氯系统的特点及实验结果，在350 ℃，停留时间10 min的条件下，一般废塑料经脱氯后，余氯含量可达0.25wt%。在相同的停留时间下，在350°C时，余氯含量比310°C时降低了0.6wt%。余氯含量在13.3min内比6.6min下降了0.14wt%，但在10 min内达到饱和。初始含氯量为1.8 ~ 45.0wt%的废塑料在350 ℃、停留时间为6.6 ~ 13.3min条件下，余氯含量为0.24 ~ 0.39wt%。通过与单螺杆、间歇反应器、回转窑等设备的比较，证实了双螺杆脱氯设备是上级脱氯设备。
The machine of dechlorination using twin screw system and a dechlorination process have developed for removing from wasted plastics including chloridized polymer. In this paper, we describe summary of twin screw extruder. characteristics and results of experiment of the machine of dechlorination and the system of dechlorination.The residual chlorine content of general wasted plastics after decWorinating have achieved 0.25wt% under 350°C, resident time of 10 minutes. And the residual chlorine content have reduced 0.6wt% under 350°C comparing to 310°C, same resident time. The residual chlorine content have reduced 0.14 wt% under 13.3 minutes comparing to 6.6 minutes, same temperature, but saturated it in 10 minutes. And the residual chlorine content of 0.24 to 0.39wt% was obtained from wasted plastics containing initial chlorine content of 1.8 to 45.0wt% under 350°C and a resident time of 6.6 to 13.3 minutes. We have confirmed the machine of dechlorination using twin screw system were superior one comparing to a single screw system, batch reactor system, rotary kiln system.
