Embodiment 1

[0080] see figure 1 , the present invention discloses a system for preparing deuterium-tritium-depleted water. The preparation system includes: hydrogen production equipment 1, oxygen delivery equipment 2, and water generation equipment 3.

[0081]The hydrogen production equipment 1 is used to prepare hydrogen and output it, or it can be only the hydrogen delivery equipment, which only transports the prepared hydrogen. At this time, the hydrogen delivery equipment is connected to the membrane separation device, and the protium in the hydrogen is separated through the membrane separation device, while the hydrogen The deuterium and tritium in the membrane cannot be filtered out from the membrane separation device. The oxygen delivery equipment provides oxygen through preparation, or only delivers oxygen; the water generation equipment includes a proton membrane, which receives hydrogen produced by the hydrogen production equipment and oxygen delivered by the oxygen delivery equ...

Embodiment 2

[0129] In this embodiment, the system for preparing low-deuterium-tritium water does not include hydrogen production equipment, but only includes hydrogen delivery equipment and membrane separation devices, and only transports the prepared hydrogen. At this time, the hydrogen delivery equipment is connected to the membrane separation device, and through the membrane separation device The protium in the hydrogen is separated, but the deuterium and tritium in the hydrogen cannot be filtered out from the membrane separation device.

[0130] Of course, the system for preparing deuterium-tritium depleted water may also include oxygen preparation equipment to prepare oxygen. The oxygen production equipment is also equipped with a palladium alloy membrane separation device (which may be similar in structure to that of Embodiment 1), which can separate radioactive isotopes in oxygen from 16O, making drinking water safer for people.

Embodiment 3

[0132] The difference between this example and Example 1 is that in this example, the hydrogen production equipment uses hydrolysis to produce hydrogen, and the prepared hydrogen is separated from the protium in the hydrogen through a palladium membrane separation device, but the deuterium and tritium in the hydrogen cannot be separated from the Membrane separation device filtered out. The oxygen delivery equipment provides oxygen through preparation, or only delivers oxygen; the water generation equipment includes a proton membrane, which receives hydrogen produced by the hydrogen production equipment and oxygen delivered by the oxygen delivery equipment to produce healthy water.

Abstract

The invention discloses a system and a method for preparing low-deuterium tritiated water. The system comprises a hydrogen production device, an oxygen delivery device and a water generation device. A deep seawater extraction device is connected with a seawater purification device. Purified seawater is delivered to the hydrogen production device to serve as part of raw materials of the hydrogen production device. The hydrogen production device is provided with a membrane separation device. Protium in hydrogen is separated out by the membrane separation device. Deuterium and tritium in the hydrogen cannot be filtered out by the membrane separation device. The oxygen delivery device provides oxygen through preparation or only delivers prepared oxygen. The water generation device receives the hydrogen produced by the hydrogen production device and the oxygen delivered by the oxygen delivery device to obtain healthy water. The system and the method have the advantages that light water not containing radioactive elements of the deuterium and the tritium can be prepared, so that life quality of people can be improved and people's demand for health can be met; in addition, the system is portable and convenient for the people to carry.

Description

technical field [0001] The invention belongs to the technical field of healthy drinking water preparation, and relates to a water preparation system, in particular to a healthy water preparation system; meanwhile, the invention also relates to a system for preparing deuterium-tritium-depleted water. Background technique [0002] Protium, deuterium and tritium are three isotopes of hydrogen; H protium has 1 proton in its nucleus, no neutrons, and its abundance is 99.98%; deuterium D (also known as deuterium), has 1 proton and 1 neutron in its nucleus , with an abundance of 0.016%; tritium T (also known as tritium), with 1 proton and 2 neutrons in the nucleus, with an abundance of 0.004. [0003] However, some studies have found that with the precipitation of time, the energy of solar radiation exists in water in the form of deuterium and tritium on the earth. Therefore, the content of deuterium and tritium in water is higher than before and is on the rise. [0004] Deuterium...
