Abstract

The invention discloses an industrial continuous production method and system of deuterium-less water. The method comprises the following steps: pretreated raw material water enters a tower group formed by connecting a plurality of rectifying towers in series to be separated, deuterated water is enriched in a liquid phase, and the deuterium-less water is enriched in a vapor phase. The led-out high-purity deuterium-free water vapor is pressurized through a compressor and then condensed in a reboiler to release heat so as to drive the rectification process, meanwhile, part of the condensed deuterium-free water is extracted as a product, and part of the condensed deuterium-free water flows back to the rectification tower to serve as reflux liquid. Tower top steam and tower bottom liquid of all the towers flow in a cross mode to form a closed-loop or stepped cycle. According to the invention, through total heat pump rectification, low-energy-consumption, high-efficiency, continuous and stable production of deuterium-less water with deuterium content reduced by 1-3 orders of magnitude is realized, and the method is easy for industrial popularization.
