RECUPERATION APPARATUS FOR TEXTILE FINISHING MACHINES Russian patent published in 1995 - IPC

FIELD: chemical and textile industry. SUBSTANCE: recuperation apparatus for textile finishing machines presents a vessel for collection of hot used solutions into which lifting heat exchanger is installed. Used hot solution is supplied to vessel through inlet and discharged through outlet. Heat exchanger is communicated with means for supply and discharge of heated water. Heat exchanger is made in form of successively connected pairs of tubes arranged in zigzag vertical parallel rows, and partitions are rigidly mounted at bottom. Partitions are alternately rigidly fastened at end face walls of vessel. When heat exchanger is lowered into vessel, tube rows are found between partitions to form channels for passage of liquid. To prevent flowing of liquid over top of partitions, heat exchanger is mounted on cover provided with guide seals engageable with partitions. Heat exchanger is lifted and lowered with the aid of drive, flexible link and block system installed on U-shaped guide posts secured at vessel base. EFFECT: higher efficiency. 6 dwg
