Abstract

A lase-of-polymerization handling device having a pat flange installed on the body wall thereof, wherein the end face of a through-hole provided in the pat flange is chamfered on the body wall inner side, whereby, since the accumulation and polymerization of lase-of-polymerization gas can be prevented from occurring at the handling device inner side end face of the pad flange used for connecting instruments such as pressure gauges and liquid level gauges, erroneous indication of the instruments can be eliminated, and safe operation can be performed for a long period.

Description

technical field

[0001] The present invention relates to a structure of a butt flange mounted on a main body wall of a processing device such as a reaction tower for preparing easily polymerizable compounds, a distillation tower, or a storage tank for storing solutions obtained therefrom. In particular, the present invention relates to a treatment device for easily polymerizable compounds that prevents gas generated from easily polymerizable compounds and the like from stagnating in through holes provided in the mating flange, and suppresses generation of polymers in this portion.
