Description

Energy-saving natural mineral substance-containing low-deuterium water production process and device Technical Field The invention relates to the field of water processing, in particular to an energy-saving natural mineral substance-containing low-deuterium water production process and device. Background Deuterium is a stable isotope of hydrogen, also known as heavy hydrogen, which differs from hydrogen atoms in that it contains a neutron, thus resulting in a difference in its physicochemical properties compared to hydrogen. Natural water has deuterium abundance of about 150ppm in nature, often related to water source location, altitude, etc., and water with deuterium abundance lower than natural water is referred to as deuterium depleted water, or ultra-light water. The research shows that the deuterium-depleted water is beneficial to improving the metabolism and the activity of cells, promoting the reaction of various enzymes of human bodies, improving the activity of natural killer cells, enhancing the immune function of human bodies, inhibiting the canceration of cells and the proliferation of cancer cells, and realizing the potential health care effects of cancer prevention. On the other hand, the natural mineral water is used as a common drink in life, and can supplement natural minerals and trace elements for human bodies. Scientific researches show that various minerals and microelements such as strontium, vanadium, sodium, potassium, magnesium, calcium and the like in natural mineral water are helpful for maintaining bone health, promoting metabolism, balancing electrolyte and the like. Therefore, the natural mineral low deuterium water contained in the composite product of low deuterium water and natural mineral water is a healthy drink beneficial to human body and rich in functions. The production process of natural mineral deuterium-depleted water involves the concentration of raw water and the preparation of natural mineral deuterium-depleted water, and currently, commercially available natural mineral deuterium-depleted water is produced by direct line filling of natural mineral water with relatively low deuterium content (e.g., 140 ppm), and the raw water is not concentrated or quality controlled, mainly because the efficient and low cost mineral concentration process and the quality control capability of natural mineral deuterium-depleted aquatic products limit the large-scale line construction. As a typical mineral concentration process, the evaporation and vaporization process can effectively realize mineral concentration in raw water, and meanwhile, compared with concentration processes such as ion exchange and reverse osmosis, the evaporation and vaporization process has the advantages of large treatment capacity and simple device structure. However, the existing evaporation vaporization device has the technical problem of high energy consumption, and a large amount of energy can be consumed for solvent evaporation and condensation, so that the operation cost of the process is high, and the investment of the related technology and the device is limited. On the other hand, the quality control technology of natural mineral low-deuterium aquatic products is deficient, and mass production of high-quality, high-quality stability and low-deuterium product water is limited. Disclosure of Invention The invention aims to provide an energy-saving natural mineral low deuterium water production process and device, which can obviously reduce the energy consumption of an evaporation concentration process by recovering heat in a low-grade heat source and converting the heat into high-grade heat energy and heating raw water in an evaporation treatment process by the high-grade heat energy, thereby realizing the optimization of an evaporation-condensation process flow and the reduction of the running cost of the device. In order to achieve the aim, the invention adopts the technical scheme that the energy-saving natural mineral substance-containing low deuterium water production process comprises the following steps: Raw material water is evaporated and condensed to obtain pure water, water vapor generated in the raw material water evaporation process is pressurized to form high-temperature high-pressure vapor, and the high-temperature high-pressure vapor is subjected to heat exchange with the raw material water in the evaporation process to heat the raw material water in the evaporation process; preparing deuterium-depleted water by pure water; mixing the deuterium-depleted water with the concentrated water obtained after the evaporation of the raw material water to obtain the natural mineral deuterium-depleted water. Further, in the mixing process of the deuterium-depleted water and the concentrated water after the raw material water is evaporated, the deuterium concentration and the mineral concentration of the deuterium-depleted water containing natural minerals are monitored in real time, and the pr
