FIELD: water-supply engineering. SUBSTANCE: this system is intended for repeated use of industrial water and can be widely employed in various branches of food and chemical industry. System has delivery pumps, cooler, cold consumer, and main pipeline connecting them to each other. System is also provided with following components: preliminary cooling stage which is connected by main pipeline with cold consumer outlet, buffer vessel which is connected by main pipeline with outlet of preliminary cooling stage and inlet to delivery pumps, shut-off and regulating device, and temperature sensor. These components are installed respectively after delivery pumps and cooler on main pipeline which connects outlet of delivery pumps with cooler, and outlet of cooler with inlet of cold consumer. Operating mechanism of shut-off and regulating device and temperature sensor are functionally connected by temperature regulator. Aforesaid arrangement of circulating water-supply system gives higher performance characteristics. EFFECT: higher efficiency. 24 cl, 29 dwg |
