CONCENTRATOR Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: concentrator has housing provided with systems for supplying a heat carrier under pressure and discharging the heat carrier. The housing of the concentrator has driving drums mounted coaxially inside the housing, branch pipes having systems for supplying initial fluid, discharging concentrated solution and secondary vapor, which are positioned at the end faces of the branch pipes, and flexible hoses which are turned inside out. The hoses are mounted in the branch pipes for permitting synchronous reciprocation. One end of the hoses is rigidly connected to the base of the branch pipes over periphery. The other end is wound on the driving drum to define outer and internal spaces. The system for supplying and discharging the heat carrier is in communication with the internal space. The branch pipes are tangentially coupled with the housing. The hoses are wound on the driving drum from one side. EFFECT: enhanced efficiency. 1 dwg
