技术领域
本实用新型属于化工设备领域，具体涉及一种生产乙氧基化衍生物的装置。
背景技术
现有的乙氧基化装置包括反应器，反应器上有抽真空管线，放空管线，氮气管线，链初始剂进料口和环氧乙烷进料口以及循环回路。乙氧基化反应的循环回路需要一定量的链初始剂以启动循环泵，如所用链初始剂的用量少，循环泵启动量就低，则仅需要小型的循环泵，小尺寸的连接管线和低热负荷的换热器，所需环氧乙烷加入流率也较低，这样的配置虽然具有很高的增长率，但是反应时间长，装置产量低。如果要加大环氧乙烷加入流率，则需要大型的循环泵、大尺寸的连接管线和高换热负荷的换热器，但大型的循环泵意味着需要大量的链初始剂量，虽然反应时间短、产量高，但增大了链初始剂的消耗量，降低了增长率。
实用新型内容

本实用新型的技术方案如下：
一种生产乙氧基化衍生物的装置，包括：

和一副循环泵，其启动量小于上述主循环泵；
反应器的副循环出料口通过副循环泵与副循环换热器的第二进料口相连通，副循环换热器的第二出料口与反应器的副循环进料口相连通。

2、本实用新型的本体的底部向下延伸形成一预反应腔，该预反应腔的内径小于反应器本体的内径，使得加入少量的链初始剂即可启动副循环泵，进而启动副循环管路，保证副循环管路的安全稳定运行。
