Problems solved by technology

[0002] Deuterium is an isotope of hydrogen that can combine with oxygen to form the molecule D 2 0 or HDO, the content in nature is about 150 parts per million, that is, 150ppm; modern research shows that the lower the content of deuterium in water, the better for health; therefore, a production process that reduces the content of deuterium in water is needed , the current existing production process is usually relatively fine, the output is not high, resulting in high production costs, which is not conducive to large-scale production

Embodiment 1

[0018] Use the following production process to prepare deuterium-free drinking water. Before preparing deuterium-free drinking water, carry out nitrogen pressure leak detection on the production equipment:

[0019] (1) Food grade sulfur (S) and hydrogen (H 2 ) synthesis to obtain H 2 S, earned H 2 S is passed into the high-temperature exchange tower and the low-temperature exchange tower in sequence;

[0020] (2) Drinking water is treated with reverse osmosis to obtain purified water; the purified water is preheated to 28°C and then passed into the low-temperature exchange tower and the high-temperature exchange tower in sequence;

[0021] (3) In the low-temperature exchange tower, pure water flows from top to bottom and H flowing from bottom to top 2 S is exchanged in the cryogenic exchange tower, H 2 The deuterium in S is transferred to pure water; the exchange time in the low temperature exchange tower is 50min~60min; the temperature in the low temperature exchange towe...

Abstract

The invention relates to the field of water processing, and concretely relates to a production process of deuterium-removed drinking water. The production process comprises H2S synthesis, reverse osmosis, preheating, low-temperature exchange, high-temperature exchange and steam desulfurization. The deuterium-removed drinking water production process makes the deuterium-removed drinking water withthe deuterium content lower than that of natural water effectively obtained, the cost of the production process can be reduced, and large-scale production is facilitated.

Description

technical field [0001] The application relates to the field of water processing, in particular to a production process for deuterium-removed drinking water. Background technique [0002] Deuterium is an isotope of hydrogen that can combine with oxygen to form the molecule D 2 0 or HDO, the content in nature is about 150 parts per million, that is, 150ppm; modern research shows that the lower the content of deuterium in water, the better for health; therefore, a production process that reduces the content of deuterium in water is needed , the current existing production process is usually relatively fine, the output is not high, resulting in high production costs, which is not conducive to large-scale production. Contents of the invention [0003] The invention provides a production process for deuterium-removed drinking water, which can effectively obtain deuterium-depleted drinking water with lower deuterium content than natural water, and can also reduce the cost of the...
