Technology for producing deuterium-depleted water and method for producing deuterium-depleted water thereby

Abstract

The invention discloses a technology for producing deuterium-depleted water and a method for producing deuterium-depleted water thereby. According to the method, hydrogen which is a byproduct of chlor-alkali industry is washed with water and cooled at a low temperature, then enters a hydrogen burner through a pipeline, is mixed with oxygen and then is burned in a hydrogen burning boiler, the heat released during the combustion of hydrogen is used for producing steam, the water generated during the combustion of hydrogen enters a cooling condensing system for cooling and condensing, and the obtained deuterium-depleted water is stored in a crude deuterium-depleted water storage tank (5); and the deuterium-depleted water in the crude deuterium-depleted water storage tank is processed by the steps of sand filtering, carbon filtering, microfiltration, ultrafilteration, reverse osmosis, refined filtration and sterilization in a water purification system and then is canned by a canning machine and finally the canned deuterium-depleted water is transported outwards to the markets. The hydrogen (a byproduct of chlor-alkali industry) is burned with oxygen to produce deuterium-depleted water with very high value. The method is low in energy consumption, has low cost, can be put into large-scale industrial production of the deuterium-depleted water, improves the quality of drinking water for people, meets the heavy demand of the mass on the deuterium-depleted water, and has good social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of stable isotopes, in particular to a process for producing deuterium-depleted water with by-product hydrogen in the chlor-alkali industry and a method for producing deuterium-depleted water using the process. Background technique [0002] Deuterium-depleted water, also known as ultra-light water, is a high-end drinking water produced by using high-tech isotope separation technology to reduce the deuterium content in water. The international standard name is: Deuterium Depleted Water, English abbreviation DDW. At present, developed countries such as Europe, America and Japan have widely used deuterium-depleted water in the fields of cancer prevention, health care, beauty care, etc. Deuterium-depleted water is known as "cell nutrition water" and "water of life". [0003] The water existing in nature is composed of 2 hydrogen atoms and 1 oxygen atom, and the hydrogen element has 3 stable isotopes with diff...

AI Technical Summary

Problems solved by technology

[0007] The glaciers are located on the plateau away from human habitation, the cost of mining and transportation is huge, and the deuterium content is not much different from that of ordinary water, so there is no large-scale mining and utilization so far

The method of water rectification, also because the boiling point difference between water and heavy water is very small, consumes a lot of energy, and there is no mass production. It is only a by-product of deuterium-depleted water in the oxygen-18 production device, and the output is very limited.
