Water rectification apparatus for enriched heavy oxygen isotope water

The utility model provides a water rectification apparatus for enriched heavy oxygen isotope water mainly comprising a plurality of series-wound or series-wound and shunt-wound rectification towers. A grain filler with a surface area being 1000 to 3000m /m and a silk filler with a surface area being 350 to 700m /m in each rectification tower. The water rectification apparatus for enriched heavy oxygen isotope water of the utility model is simple in structure, convenient in operation, low in manufacturing cost. The water rectification apparatus for enriched heavy oxygen isotope water of the utility model is adopted, and can obtain heavy oxygen isotope oxygen gas with a concentration of heavy oxygen isotope oxygen being 10 to 97% atomic. Besides, the heavy oxygen isotope oxygen gas is used as a material of producing heavy oxygen water, and a heavy oxygen water with the concentration of the heavy oxygen isotope oxygen being 10 to 97% atomic and deuterium being natural density is attained.
