Title:
易重合性化合物の取り扱い装置及び製造装置
Document Type and Number:
Japanese Patent JP4466190
Kind Code:
B2
Abstract:
A condenser (20) includes: a top face of a tube plate (33) on which acrylic acid may be condensed inside the condenser (20); a spray (35) for spreading a polymerization inhibitor on the tube plate (33); a first polymerization inhibitor supply tube (28) for supplying the polymerization inhibitor to the spray (35); and a supporter (36) for supporting the spray (35) at a predetermined position. The supporter (36) supports the first polymerization inhibitor supply tube (28) outside the condenser (20). The present invention allows a stable continuous operation of an apparatus having a condenser for a long period of time by preventing polymerization of an easily polymerizable compound in the condenser into which a vapor of an easily polymerizable compound is supplied with a simple structure thereof.
