Abstract

本实用新型涉及一种1,4-环己烷二异氰酸酯蒸馏装置,包括蒸发器和接收罐,所述的蒸发器与接受罐之间连一管道,其特征在于:所述的管道带有夹层,内层通1,4-环己烷二异氰酸酯,外层通蒸汽。本实用新型的优点在于:蒸发时,1,4-环己烷二异氰酸酯从蒸发器顶端出料,出料管道通蒸汽加热,防止物料冷凝,堵塞管路,将1,4-环己烷二异氰酸酯送入接收罐内。

Description

一种1,4-环己烷二异氰酸酯蒸馏装置
技术领域
本实用新型涉及一种1,4-环己烷二异氰酸酯蒸馏装置。
背景技术
1,4-环己烷二异氰酸酯,分子式为C6H10(NCO)2,是一种新型特种二异氰酸酯,比常用的二异氰酸酯分子量小,在聚氨酯合成中,只需少量的1,4-环己烷二异氰酸酯参与反应即可获得卓越的性能。1,4-环己烷二异氰酸酯在合成过程中,由于该物质凝固点高,在蒸发出料时,由于出料管温度低于蒸发器内温度,1,4-环己烷二异氰酸酯在出料管上容易凝结为固体,堵塞管路,影响反应的进行。
发明内容
本实用新型的目的提供一种1,4-环己烷二异氰酸酯出料管上带夹套的蒸发装置。
为了解决上述技术问题,本实用新型采用的技术方案为:一种1,4-环己烷二异氰酸酯蒸馏装置,包括蒸发器和接收罐,所述的蒸发器与接收罐之间连一管道,其特征在于:所述的管道带有夹层,内层通1,4-环己烷二异氰酸酯,外层通蒸汽。
本实用新型的优点在于:蒸发时,1,4-环己烷二异氰酸酯从蒸发器顶端出料,出料管道通蒸汽加热,防止物料冷凝,堵塞管路,将1,4-环己烷二异氰酸酯送入接收罐内。
附图说明
图1为本实用新型1,4-环己烷二异氰酸酯蒸馏装置结构示意图。
具体实施方式
如附图可知,包括蒸发器1、接收罐2。
 所述的蒸发器1与接收罐2之间连有一管道,所述的管道带夹层,内层通1,4-环己烷二异氰酸酯,外层通蒸汽。
蒸发时,1,4-环己烷二异氰酸酯从蒸发器顶端出料,出料管道通蒸汽加热,防止物料冷凝,堵塞管路,将1,4-环己烷二异氰酸酯送入接收罐内。
