specific Embodiment

[0044] The waste water in the production process of deuterium-depleted water enters the water storage tank 8 through the diaphragm vacuum pump 3 and the pipeline to cool down and naturally cools to the ambient temperature of 20-28°C, and the cooled waste water is transported to the deuterium-depleted water condensation chamber 12 through the pipeline centrifugal pump 7 Use as condensate. The used high-temperature condensed water passes through the cooling tower 9 to dissipate heat to below 35°C and then flows back into the water storage tank 8, thereby realizing zero discharge and recycling of deuterium-depleted wastewater. Municipal pipe network water is used as supplementary water for storage tank 8 . After the water volume of the water storage tank 8 reaches the specified water level, close the municipal pipe network water supply valve 5, open the pipeline centrifugal pump 7 and the valve 5, and use the water source in the water storage tank 8 to supply condensed water to t...

Description

technical field [0001] The invention relates to the technical field of deuterium-depleted water production, in particular to a deuterium-depleted water wastewater recycling device and method. Background technique [0002] Deuterium-depleted water refers to water with a deuterium content lower than 150ppm. Experimental studies have shown that deuterium-depleted water has a variety of biological effects beneficial to the human body: such as activating human cells, enhancing human immunity, and preventing cancer and health care. The large-scale production methods of deuterium-depleted water mainly include electrolysis, distillation and water / hydrogen dual-temperature exchange method. Among them, the distillation method is widely used because it does not require the use of catalysts or chemical reagents, and the production process is simple and mature. The distillation method to prepare deuterium-depleted water is carried out in a distillation tower equipped with several trays o...
