Embodiment 1

[0032] Such as figure 1 Shown, ion exchange technology prepares the production device of distilled water, and it comprises sand filter tank 1, activated carbon filter 5, ultraviolet sterilizing device 8, water inlet pump 9, distilled water machine 10 and distilled water storage tank 12, it also comprises softener 3, ion Exchanger 4, 5 μm fine filter 6 and 1 μm fine filter 7, sand filter cylinder 1, water softener 3, ion exchanger 4, activated carbon filter 5, 5 μm fine filter 6, 1 μm fine filter 7, ultraviolet sterilizing device 8, water inlet pump 9. The distilled water machine 10 and the distilled water storage tank 12 are connected successively; the regenerant used by the ion exchanger 4 is 30% hydrochloric acid and 99% flake solid sodium hydroxide diluted with water to a 30% regenerant.

[0033] This embodiment also includes a 5 μm coarse filter 2, a 0.2 μm fine filter 11, a filling pump 13 and a stainless steel element filter 14, the 5 μm coarse filter 2 is connected betw...

Embodiment 2

[0048] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the production device for preparing distilled water by the ion exchange technology described in this embodiment also includes an ozone generator 15 , and the ozone generator 15 is connected to the distilled water storage tank 12 .

[0049] Wherein, the ozone concentration added by the ozone generator 15 is above 0.6 mg / L. Ozone sterilizes distilled water, and at the same time has decolorization, deodorization, removal of iron, manganese, oxidative decomposition products and coagulation aid. It is necessary to detect the index of distilled water in the distilled water storage tank 12 once per hour, requiring O 3 Concentration ≥ 0.6mg / L, conductivity ≤ 10 uS / cm, pH value 5.0-7.0, turbidity ≤ 1NTU and no visible matter can be detected. Then it is delivered to the distilled water bottle by filling pump 13 for filling.

[0050] Features that are not explained in this embodiment are...

Abstract

The invention relates to a distilled water preparation technology field, concretely a production device for preparing distilled water by an ion exchange technology, comprising: a sand filtration cylinder, an activated carbon filter, an ultraviolet sterilization device, a water inlet pump, a distilled water machine and a distilled water storage cylinder, and further comprising a water softener, an ion exchanger, a 5mum fine filter and a 1mum fine filter, wherein the sand filtration cylinder, the water softener, the ion exchanger, the activated carbon filter, the 5mum fine filter, the 1mum fine filter, the ultraviolet sterilization device, the water inlet pump, the distilled water machine and the distilled water storage cylinder are connected in order; and regenerants are 30% hydrochloric acid and a 30% of regenerant diluted from 99% sheet-shaped solid sodium hydroxide with water. The device provided by the invention can effectively remove pollutants in water and guarantees the water yield of the distilled water machine.

Description

technical field [0001] The invention relates to the technical field of distilled water preparation, in particular to a production device for preparing distilled water by ion exchange technology. Background technique [0002] Distilled water is to heat tap water in a distilled water machine to 105°C to 108°C, tap water evaporates into water vapor, and then condenses into distilled water. After a period of normal operation of the distilled water machine, the heat exchange plate of the distilled water machine will be polluted by suspended substances or insoluble substances that may exist in tap water. The most common of these pollutants are calcium carbonate scale, calcium sulfate scale, and metal oxides. scale, silicon deposits and organic or biological deposits. If measures to remove pollutants are not taken, the pollution will block the heat exchange fins in a relatively short period of time, affect heat transfer efficiency, reduce water production, and increase energy cons...
