Title:
有機溶剤濃縮装置および有機溶剤濃縮装置の劣化判定方法
Document Type and Number:
Japanese Patent JP7347795
Kind Code:
B2
Abstract:
The present invention provides a method capable of reducing the time until deterioration determination and also reducing the hassle of drilling by simplifying a method of determining the deterioration of a VOC adsorption honeycomb rotor. According to the organic solvent concentrating apparatus and the method for determining deterioration of the organic solvent concentrating apparatus of the present invention, only by measuring the amount of organic matter accumulation by TG/DTA, a static adsorption rate can be predicted without performing a VOC static adsorption test, the method of determining the deterioration of the VOC concentrating rotor can be simplified, and the trouble and time of the investigation can be reduced. According to the present invention, 20 to 100 mm is taken out from the entire VOC adsorption honeycomb rotor in the thickness direction, or both ends or either end of the treatment inlet side and the treatment outlet side toward the center in the thickness direction of the VOC adsorption honeycomb rotor.
