一方向に回動するネット状のエンドレスベルト上に前記ペレット状の重合体を連続的に移載して密閉された熱風乾燥室内を移送させ、その移送の間に乾燥させること、
洗浄水流路が前記エンドレスベルトの上下ベルト部の間に介装され、同回動路を横断するとともに同ベルトの上ベルト部の端縁部から下ベルト部の反対側の端縁部に向けて下傾斜する洗浄水流路上に水を流して、上ベルトから落下する前記重合体の粉末とともに前記洗浄水流路上を流下させること、
前記洗浄水流路を水と一緒に流下した含水重合体粉末を、前記洗浄水流路の下端部に配された滞留部に滞留させること、
前記滞留部に滞留する前記含水重合体粉末を回収すること、
を含んでなることを特徴とするアクリルニトリル系重合体の連続乾燥方法。 A method for drying a pellet-shaped polymer after dehydrating and washing a slurry composed of a mixture of a polymer and water obtained in a polymerization step of an acrylonitrile-based polymer,
Continuously transferring the pellet-like polymer onto a net-like endless belt rotating in one direction and transferring it in a sealed hot air drying chamber, and drying during the transfer;
A washing water flow path is interposed between the upper and lower belt portions of the endless belt, traverses the rotation path, and from the edge of the upper belt portion of the belt toward the edge opposite to the lower belt portion. Flowing water over a downwardly inclined wash water flow path and causing the polymer powder falling from the upper belt to flow down the wash water flow path;
Causing the water-containing polymer powder that has flowed down along with the water in the washing water flow path to stay in a staying portion disposed at a lower end of the washing water flow path;
Recovering the water-containing polymer powder retained in the retention part;
A process for continuously drying an acrylonitrile-based polymer comprising:
