Treatment facility of nitromethane waste water of high salinity

The utility model relates to a chemical industry field discloses a treatment facility of nitromethane waste water of high salinity very much. This treatment facility of nitromethane waste water of high salinity, including first vaporization tower, second vaporization tower, third vaporization tower and fourth vaporization tower, fourth vaporization tata bottom side discharge gate is linked together with first vaporization tower feed inlet, and the ejecting gas port of first vaporization tata is linked together with the shell side entry on second reboiler upper portion, and the ejecting gas port of second vaporization tata is linked together with the shell side entry on third reboiler upper portion, and the ejecting gas port of third vaporization tata is linked together through the shell side entry of pipeline with fourth reboiler upper portion. This treatment facility of nitromethane waste water of high salinity, the system appears when having avoided adopting pressure differential to carry suppresses the pressure phenomenon, the heat energy of reuse steam many times, waste water material from the top feeding of reboiler, bottom discharge, the reboiler is inside can not to produce the material stock, has avoided the phenomenon that takes place sodium sulphate wall built-up, plug the pipe.
