Embodiment 1

[0030] Such as figure 1 As shown, the reverse osmosis desalination technology is applied to the production device for preparing distilled water, which includes a raw water tank 1, a raw water pump 2, a multimedia filter 3, an activated carbon filter 4, a 5 μm filter 5, a 1 μm filter 6, and a high-pressure Pump 7, secondary reverse osmosis device 8, intermediate water tank 9, distilled water machine 10, 0.2 μm filter 11, distilled water tank 12, produced water pump 13;

[0031] The tap water is delivered to the raw water tank 1, and the raw water tank 1 adopts an aeration process to reduce the depth of residual chlorine in the tap water. When in use, detect the residual chlorine and pH value of the tap water in the raw water tank 1 once a day to ensure that the residual chlorine in the tap water is ≤0.8mg / L and the pH value is 6.5-8.5; detect the microorganisms once a week to ensure that the total number of colonies in the tap water is ≤100cfu / mL, coliform bacteria ≤3MPN / mL. ...

Embodiment 2

[0039] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment also includes a 0.2 μm filter 15, which is connected to the produced water pump 13; the distilled water is filtered through the 0.2 μm filter 15, and then filling. The 0.2 μm filter 15 removes particles larger than 0.2 μm in the water to improve the cleanliness of the water. The water pressure difference between the inlet and outlet of the 0.2 μm filter 15 should be greater than 10Psi.

[0040] Features that are not explained in this embodiment are explained in Embodiment 1, and will not be repeated here.

[0041] The various indexes of the distilled water prepared by Embodiment 1 and Embodiment 2 of the present invention are inspected, and the inspection results are shown in Table 1.

[0042] Table 1

[0043] .

[0044] As can be seen from Table 1, the quality of the distilled water prepared by the present invention is good, and each test index is all qual...

Abstract

The invention relates to the technical field of distilled water preparation, and concretely relates to a production apparatus for preparing distilled water by applying a reverse osmosis desalination technology. The apparatus comprises a raw water tank, an activated carbon filter, a high pressure pump, a distilled water machine and a distilled water tank, and also comprises a 5mum filter, a 1mum filter, a secondary reverse osmosis device and a 0.2mum filter, and the raw water tank, the activated carbon filter, the 5mum filter, the 1mum filter, the high pressure pump, the secondary reverse osmosis device, the distilled water machine and the distilled water tank are sequentially connected. The apparatus can effectively remove pollutants in water and can guarantee the water output 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 in which reverse osmosis desalination technology is applied to prepare distilled water. 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 produc...
