Detailed description of the invention
Below by specific embodiment and combine accompanying drawing and describe in this utility model a kind of useless
Water vacuum flashing concentration systems.Unless stated otherwise, technological means used in this utility model
It is method known in those skilled in the art.It addition, embodiment is interpreted as illustrative
, and unrestricted scope of the present utility model, spirit and scope of the present utility model is only by right
Claim is limited.To those skilled in the art, without departing substantially from this utility model essence
On the premise of scope, carry out the material component in these embodiments and consumption various changes
Become or change and fall within protection domain of the present utility model.
A kind of waste water vacuum flashing concentration systems, including:
Waste water heat exchange unit, gives up including the wastewater trough 1 being sequentially connected with, waste water pump 2, two grades
Water-to-water heat exchanger 4 and primary wastewater heat exchanger 5, described primary wastewater heat exchanger 4 is also associated with steaming
Steam control valve 6, described secondary waste water heat exchanger 4 and primary wastewater heat exchanger 5 all use tubular type
Heat exchanger；
Waste water fine vacuum upgrading unit, including demister 8 and flash tank 7, flash tank 7 with remove
Foam device 8 connects, and demister 8 is connected with wastewater trough 1 and primary wastewater heat exchanger 5 the most respectively；
