Embodiment Construction

[0015] A preparation method of ultra-light water, the steps of the method are as follows:

[0016] 1. Select the reaction tower as the ultra-light water preparation device. The reaction tower is divided into two parts: the cooling tower and the heat tower. The Pt / SDB hydrophobic catalyst with a particle size of 2mm is selected as the catalyst for the cooling tower, and the Pt / PTFE with a particle size of 3mm is selected. Hydrophobic catalyst as catalyst for hot tower;

[0017] 2. Select quartz glass tubes with an inner diameter of 20mm and a length of 600mm as the cooling tower and the hot tower, and put the Φ2mm θ ring hydrophilic packing and the hydrophobic catalyst into the cooling tower and the hot tower in layers at a ratio of 3:1 by volume , according to the order of one layer of hydrophobic catalyst and one layer of hydrophilic filler, then one layer of hydrophobic catalyst and one layer of hydrophilic filler, the total filling height is 400mm.

[0018] 3. Connect the ...

Abstract

The invention discloses a deuterium depleted water preparation method which overcomes the defects that an existing preparation method is high in energy consumption and low in separation coefficient and causes pollution. The method includes the steps of selecting a reaction tower as a deuterium depleted water preparation device, selecting a catalyst of a cold tower as the Pt / SDB hydrophobic catalyst, selecting a catalyst of a hot tower as the Pt / PTFE hydrophobic catalyst, filling a bed layer of the cold tower and a bed layer of the hot tower with the hydrophobic catalysts and hydrophilic filler, connecting the cold tower with the hot tower in series with the hot tower on the upper side and the cold tower on the lower side, selecting deionized water as the raw material water and high-purity hydrogen as the raw material gas, introducing the raw material water and the raw material gas into the reaction tower, conducting a chemical exchange reaction on the raw material water and the raw material gas in the cold tower and the hot tower, and obtaining fluid flowing out of the tower bottom of the hot tower as deuterium depleted water subjected to primary exchange. The method is simple in principle, process and device, large in disposal amount, capable of saving energy, free of pollution, and suitable for large-scale production of deuterium depleted water beverages.

Description

technical field [0001] The invention belongs to the technical field of hydrogen isotope separation, in particular to a preparation method of ultra-light water. Background technique [0002] In the field of nuclear industry, both deuterium and heavy water are very important industrial raw materials. However, according to many research results, deuterium is harmful to the survival and reproduction of living organisms. After the protium atoms in the DNA helical structure are replaced by deuterium, the phase shift, breakage or replacement of the helical structure will be caused, and the ribonucleic acid arrangement will be disordered or even mutated. Once deuterium enters the living body, it is difficult to metabolize and remove it. High levels of deuterium have adverse effects on the genetics and metabolism of the human body. D in natural water 2 The O content is about 150ppm, and the living body has already produced adaptability, if the D in the water 2 If the O content ex...
