In the field of environmental protection, water resources are a necessity and a subject of survival. Not only sewage filtration to obtain clean water resources, but also to obtain sufficient water resources from the vast sea water.

Most of the traditional water treatment methods use electric heating distillation or steam heating distillation. In addition to harsh use conditions, it consumes a lot of energy, which is more likely to cause fire and endanger the safety of life and property.

The common water treatment method adopts the liquid phase filtration process to filter out most of the impurities other than water through materials such as tubular membranes, resulting in unsatisfactory water cleanliness.

Other water treatment methods, such as biochemical treatment. However, the biochemical treatment method often requires a large amount of chemical agents. In addition to the unstable reaction process, many dangerous solid wastes will also be produced, causing secondary pollution.

In the following description, "plurality" means two or more, unless otherwise specified.

As shown in Figure 1, this creation is a preferred embodiment of a set of water treatment equipment. In this embodiment, the water treatment equipment lays some pipelines from a bucket 11 to a water storage tank 40, including, but not limited to:

A filter line 12 is connected from the vat 11 to a distillation vat 20 . The filter pipeline 12 is provided with a first pump 13 and a liquid phase filter 14 . In some embodiments, at least one filter 17 is added to the filter pipeline 12 .

A grease circuit 16 returns from the liquid phase filter 14 to the barrel 11 .

An infusion pipeline 22, which is connected to a closed inner space of the distillation barrel 20, forms a circulating flow channel together. The infusion line 22 exchanges heat with a heat pump system 30 . A second pump 23 is installed on the infusion line 22 .

A water pipe 41 is connected from the inner space of the still 20 to the water storage tank 40 which is connected to a third pump 42 . Moreover, the water pipe 41 maintains heat exchange with the heat pump system 30 .

Specifically, the liquid phase filter 14 includes: an oil-water separation membrane 15 for filtering out most substances other than water, such as industrial emulsion and grease. Wherein, the oil-water separation membrane 15 is selected from polyvinylidene fluoride (PVDF), polyvinylpyrrolidone (PVP), polyphenylene ether (PES), polystyrene (PS), polyacrylonitrile (PAN), silicon dioxide (SiO ₂ ), Alumina (Al ₂ O ₃ ), Sodium Chloride (NaCl) or a composite material of the above arrangements, made into one type of roll membrane, flat membrane, hollow fiber membrane, tubular membrane and ceramic membrane state.

The filter 17 referred to here generally refers to a reverse osmosis (RO) water filter, or other water filters. Since the filter 17 is between the liquid phase filter 14 and the distillation drum 20 , the water flowing into the distillation drum 20 is filtered again by the filter 17 .

Next, an air pressure regulator 21, such as an air compressor, is connected to the distillation drum 20, and the pressure value inside the distillation drum 20 can be changed. A plurality of gas-phase filters 26 are arranged side by side at the point where the inner space of the distillation barrel 20 leads to the water pipe 41 , and each gas-phase filter 26 includes a membrane 28 as shown in FIG. 2 . The film 28 is selected from polypropylene (PP), polyvinylidene fluoride (PVDF), hexafluoropropane (HFP), polytetrafluoroethylene (PTFE) or a composite material of the above arrangements, to make a waterproof breathable high porosity film , or a hydrophobic porous film.

Looking back at FIG. 1 , the heat pump system 30 is distinguished: a heat release line 32 and a heat absorption line 35 . The heat release line 32 is connected from a compressor 31 to an expansion valve 34, and a condenser 33 is arranged in the heat release line 32, and the condenser 33 and the liquid infusion line 22 maintain heat exchange. The heat absorption line 35 is returned to the compressor 31 through the expansion valve 34 , and an evaporator 36 is arranged in the heat absorption line 35 , and the evaporator 36 maintains heat exchange with the water pipe 41 . In other words, the compressor 31 , the condenser 33 , the expansion valve 34 and the evaporator 36 are connected to form a circulation pipeline for heat exchange, so the heat pump system 30 is also called a heat exchanger.

In conjunction with Figures 1 and 2, the use state of the water treatment equipment is further described. When the barrel 11 receives some liquid 10 to be filtered, the first pump 13 is activated, so that the liquid 10 to be filtered flows from the barrel 11 into the filter pipeline 12, and the oil-water separation membrane 15 of the liquid phase filter 14 is separated into the filtrate 18 and the filtrate. fluid substance. The filtrate 18 enters the distillation barrel 20 to become liquid water 24 . The flowing substance is returned to the barrel 11 through the grease circuit 16, mixed with other liquids 10 to be filtered, and waits for the next filtering operation.

Among them, the liquid phase filter 14 belongs to the liquid phase filtration operation. ) about 10,000 mgL-1 to 20,000 mgL-1 of the filtrate 18. Of course, the filter 17 is also a liquid phase filtration operation, so that the chemical oxygen demand (COD) of the filtrate 18 is reduced to a lower level.

After being powered on, the compressor 31 converts electrical energy into mechanical energy to generate high-pressure and high-temperature gas, which flows to the condenser 33 via the heat release line 32 . The condenser 33 discharges heat energy to generate a high-pressure and medium-temperature liquid, which flows to the expansion valve 34 via the heat release line 32 . The expansion valve 34 expands the liquid to produce low pressure and low temperature characteristics, and flows to the evaporator 36 through the heat absorption line 35 . The evaporator 36 absorbs heat energy to generate low-pressure and low-temperature gas, which is returned to the compressor 31 through the heat release pipeline 32 . The compressor 31 squeezes the gas to generate high-pressure and high-temperature gas again. Therefore, the heat pump system 30 utilizes the principle of cold air and heat circulation to perform the functions of cooling and heat exchange.

The second pump 23 is activated, so that the liquid water 24 flows from the distillation barrel 20 into the infusion pipeline 22 , exchanges heat with the condenser 33 , and then returns to the distillation barrel 20 . Under the action of heat conduction, the condenser 33 discharges heat energy, which relatively increases the temperature of the liquid water 24 in the infusion pipeline 22 .

At a standard atmospheric pressure, the temperature at which water boils is 100 degrees Celsius, also known as the boiling point of water. The boiling point changes due to changes in air pressure, an increase in air pressure increases the boiling point, and a decrease in air pressure decreases the boiling point. For example, according to a set value, the gas pressure regulator 21 changes the pressure value of the inner space of the distillation barrel 20 to lower the boiling point to 50°C to 60°C.

Even if the distillation barrel 20 is in a standard atmospheric pressure environment, the liquid water 24 receives the heat energy of the condenser 33 and rises to the boiling point of 50°C to 60°C, and still evaporates into water vapor 25 in the inner space of the distillation barrel 20, thereby into the gas phase filter 26 . In this way, the film 28 allows gaseous (such as water) molecules to pass through, but intercepts liquid water droplets containing particles (such as impurities), so the chemical oxygen demand (COD) is reduced to about 100 mgL-1, which relatively improves the degree of cleanliness and completes a A gas phase filtration operation.

The section of the water pipe 41 that directs the water vapor 25 from the distillation drum 20 to the evaporator 36 is considered a section of the vapor section 27 , which releases thermal energy to the evaporator 36 , condensing the water vapor 25 into water and flowing to the water storage tank 40 . Therefore, the third pump 42 can draw clean water from the water storage tank 40 .

Those skilled in the art can understand and make changes to the above-mentioned embodiments without departing from the broad concept of the present case. Therefore, this case is not limited to the specific embodiments disclosed in the specification, and any modifications made according to the spirit and technical scope of this case should be covered and protected by the text content defined in the scope of the patent application.
