Description

Technical Field

[0001] The present invention relates to the technical field of pure water equipment, in particular to a distilled pure water machine. Background Art

[0002] Distilled pure water machine is a kind of equipment used to prepare pure water. Distilled pure water machine, also known as distilled water machine, is a machine that prepares pure water by distillation. It can be divided into single distillation and multiple distillation water machine. This equipment works under high vacuum conditions and has the characteristics of low distillation temperature, high system vacuum, short material heating time, and high degree of separation. The separation process of the distilled pure water machine is irreversible, without boiling bubbling phenomenon, and is very suitable for separating high boiling point, heat-sensitive and easily oxidized substances. Therefore, distilled pure water machine is widely used in many fields such as the extraction of effective ingredients of vitamins and Chinese herbal medicines in the pharmaceutical industry, petrochemical industry, food industry, cosmetics industry, etc.

[0003] Existing pure water machines basically use reverse osmosis membrane filtration to produce pure water, which has at least the following problems: (1) Due to the unstable quality of the source water and the natural life of the reverse osmosis membrane, the reverse osmosis membrane system of the household water purifier basically needs to be replaced once a year, and the cost of each replacement ranges from 400 to 800 yuan; according to the general household type, the daily output of pure water is about 5L, which is equivalent to the cost of 500 / 360 / 5=0.28 yuan / L per liter of pure water; (2) When the quality of the reverse osmosis membrane declines and the water quality does not meet the requirements, users will not be aware of this and may consume substandard water. This is especially true in rural areas and small and medium-sized cities where the water quality is unstable and the risk may be even greater. (3) Reverse osmosis membranes are mostly made of plastic materials. Under long-term erosion by high-pressure water, there is a safety hazard that plastic particles may enter drinking water and endanger health. (4) The water outlet of the reverse osmosis membrane is connected to the atmosphere, which may breed bacteria and pollute the water quality; (5) The water production ratio of the reverse osmosis membrane treatment process is relatively small, resulting in a large amount of water waste. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a distilled pure water machine to solve the problems of high cost, low water production ratio and potential safety hazards in the existing reverse osmosis membrane filtration method for producing pure water.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides a distilled pure water machine, including a first container, a second container, a heating mechanism and a gas compression mechanism, the first container and the second container can transfer heat to each other; the first container is used to contain pure water, the second container is used to contain source water, and the heating mechanism is used to heat the source water in the second container to the evaporation temperature; the gas compression mechanism is used to extract the air and water vapor in the second container, and compress it into high-temperature water vapor and then pass it into the first container, the heat of the high-temperature water vapor is absorbed by the pure water and converted into distilled pure water, and the first container is also used to transfer the heat absorbed by the pure water to the source water in the second container.

[0007] Preferably, the first container is sleeved on the outer wall of the second container.

[0008] Preferably, the second container is a sealed container.

After actual operation tests, the device only consumes 0.14KW.h of electricity to produce 1 liter of water. The electricity price is 0.8 yuan, and the cost of distilled pure water per liter is only 0.12 yuan, while the membrane cost of the reverse osmosis membrane is 0.28 yuan / L, and the electricity cost of the high-pressure water required by the reverse osmosis membrane is not included.

[0020] Unless otherwise clearly specified and limited, the terms "connection", "fixation" and "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] Example 1 like Figure 1As shown, an embodiment of the present application provides a distilled pure water machine, including a first container 1, a second container 2, a heating mechanism 3 and a gas compression mechanism 4, wherein the heating mechanism is an electric heating tube, and the electric heating tube is arranged at the bottom of the second container. The gas compression mechanism is a gas compressor. The second container is a sealed container, and the first container is an open container. The second container 2 is sleeved on the outer wall of the first container 1, and the first container and the second container can transfer heat to each other; the first container is used to contain pure water, and the second container is used to contain source water, and the heating mechanism is used to heat the source water in the second container to the evaporation temperature; the gas compression mechanism is used to extract the air and water vapor in the second container, and compress it into high-temperature water vapor and then pass it into the first container, and the heat of the high-temperature water vapor is absorbed by the pure water and converted into distilled pure water, and the first container is also used to transfer the heat absorbed by the pure water to the source water in the second container.

[0022] The first container has a high-temperature water vapor inlet 5, the second container has an exhaust port 6, the gas compression mechanism includes a gas inlet 7 and a high-temperature water vapor exhaust port 8, the gas inlet of the gas compression mechanism is connected to the exhaust port of the second container through a pipeline, and the high-temperature water vapor exhaust port of the gas compression mechanism is connected to the high-temperature water vapor inlet of the first container through a pipeline.

[0023] Combination Figure 2 The working principle of the distilled water machine of this embodiment is as follows: Before starting, add source water to the second container 2, specifically, tap water can be injected, add pure water to the first container 1, and then start the electric heating mechanism 3 to preheat the source water in the second container 2. When the water temperature of the source water in the second container rises to the evaporable temperature, stop preheating, start the gas compression mechanism 4 to extract the air in the second container 2, so that a vacuum is generated in the second container 2, so that the source water evaporates at a relatively low temperature and produces water vapor. The water vapor is extracted and compressed into high-temperature water vapor by the gas compression mechanism 4. The high-temperature water vapor enters the first container 1, and its heat is absorbed by the pure water and converted into distilled pure water. The temperature of the pure water rises to obtain high-temperature pure water. The source water in the second container 2 evaporates under low pressure and takes away heat, and the temperature decreases, so that a certain temperature difference is generated between the second container and the first container. The high-temperature pure water in the first container 1 will transfer heat to the source water in the second container to maintain its temperature and continue to evaporate. The amount of condensed pure water in the first container 1 continues to increase, and the source water in the second container is continuously replenished through the external water replenishment device.
