Device for heating material water by using waste heat of water distiller

The utility model discloses a device for heating material water by using waste heat of a water distiller. The device comprises an industrial steam inlet pipe (1), a one-effect evaporator (2), condensed water discharging pipes (3 and 4), a concentrated water discharging pipe (5), a first water inlet pipe (6), a second water inlet pipe (7), a tube type heat exchanger (8), a tube type heat exchanger water outlet pipe (10) and a water collecting pipe (15). The device is characterized in that the first water inlet pipe (6), the tube type heat exchanger (8), a third water inlet pipe (14), the one-effect evaporator (2), a dual-effect evaporator (11), a three-effect evaporator (12), a four-effect evaporator (13), a five-effect evaporator (16) and a six-effect evaporator (17) are sequentially connected, and the water collecting pipe (!5) is respectively connected with the condensed water discharging pipes (3 and 4), the concentrated water discharging pipe (5), the first water inlet pipe (6) and the second water inlet pipe (7). The device has the beneficial effects of saving a large quantity of steam and electric energy, saving energy and reducing emission.
