Description

Technical Field

[0001] The present invention belongs to the field of reverse osmosis water purification, and in particular, relates to a reverse osmosis portable water purification device suitable for high water temperature and a use method thereof. Background Art

[0002] In the case of long-term outdoor adventures, disaster relief, and geological exploration, water sources are often not carried, so it is necessary to obtain drinking water on site. However, the quality and temperature of outdoor water are complicated, and the suspended matter, hardness, ions, and microorganisms in different environments are different. In order to improve the drinking water safety of workers who work in the field for a long time, it is necessary to develop a portable water purification device that is easy to carry, simple, economical, and can purify water to meet drinking requirements. With the development of water purification technology, reverse osmosis water purification technology has become more and more widely used due to its high efficiency and economical water purification effect.

[0003] Reverse osmosis water purification technology is a water purification technology that separates salt, colloid, microorganism, organic matter, heavy metals and other substances in water from water under the action of a higher osmotic pressure than the solution, so as to obtain water quality that meets the requirements. The pore size range of reverse osmosis membrane is usually 0.1nm ~ 0.7nm, and the maximum operating temperature is 40℃. As the water temperature increases, the viscosity of water decreases, and the water output increases, but the movement of water molecules intensifies, and the membrane pore size increases, making it easier for some small molecular solutes to penetrate the membrane pores, thereby reducing the desalination rate and deteriorating the quality of purified water.

[0004] Patent document CN218810964U is not suitable for reverse osmosis water purification work at high water temperature.

[0005] Existing reverse osmosis water purification devices suitable for high water temperatures mostly use heat recovery devices at the front end of the water purification, and the matching pumps, pipes, and containers have high pressure and corrosion resistance requirements. For example, the water purification device disclosed in the patent document with publication number CN210206467U is large in size and has poor water quality. It usually requires multi-stage reverse osmosis to treat concentrated water and is mostly used for industrial wastewater recovery. It is not suitable for field environments and is not portable.

[0006] Another type of reverse osmosis water purification device suitable for high water temperature often uses a composite reverse osmosis membrane. The production process of this type of membrane is to improve the heat resistance of the reverse osmosis membrane by multiple times of infiltration and drying of the casting liquid. For example, the reverse osmosis membrane preparation method disclosed in the patent document with publication number CN108525532A, but this type of membrane has poor stability, high price, poor mechanical properties, and is not suitable for operation in complex outdoor geographical environments and extreme working conditions.

[0007] The purpose of the present invention is to design a portable reverse osmosis water purifier with good heat resistance and water quality that meets drinking requirements at high water temperature, in order to address the problems of poor heat resistance, poor purified water quality at high temperature, and inconvenience in carrying in the wild in existing reverse osmosis water purifiers.

[0039] DETAILED DESCRIPTION

[0040] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0041] According to the present invention, a portable reverse osmosis water purification device suitable for high water temperature includes an outer packaging box 1, a control panel 12, a pipeline control system, a pre-filter component 5, a high-pressure pump 6, and a reverse osmosis filter component 7. The high water temperature refers to above 40°C.

[0042] The outer packaging box 1 includes a box body and an upper cover 11. The upper cover 11 is connected to the box body by hinges and buckles, and is easy to open. The protective shock-absorbing cotton is glued to the inner wall of the box body. The box body is specifically a backpack box body. A carrying strap is installed at the bottom of the box body, which can be carried in the wild. At the same time, a handle is installed on the side to meet various transportation methods. The box body is made of carbon fiber, which is light and reliable, easy to carry, strong and wear-resistant. There is a sealing strip between the upper cover 11 and the box body, which is waterproof and dustproof, and can adapt to various complex environments in the wild.

[0043] The control panel 12 is installed above the box body. By opening the upper cover 11, the operating status of the portable reverse osmosis water purification device can be monitored and various operation controls can be completed. The salinity display, pressure display, water inlet 22 of the water inlet pump, waste water outlet 23, concentrate outlet 24 and water outlet 25 of the reverse osmosis assembly 7, and the power switch are all located on the control panel 12. The control panel 12 is made of the same material as the box body, both of which are made of carbon fiber to achieve the effects of shock resistance, collision resistance and portability.

[0044] The shock-absorbing cotton is made of high-density EVA material, which can fix various water purification components and has the function of shock absorption and protection. At the same time, it can reduce the noise generated by the high-pressure pump and also play a role in heat preservation for the pipeline.

[0045] The pre-filter assembly 5 includes a self-priming pump 51 and an activated carbon filter 52. The self-priming pump 51 draws water from the source through the water intake pipe into the activated carbon filter 52, avoiding the situation where the manual water purifier needs to be close to the water source to take water. A filter is installed at the other end of the water intake pipe to filter large impurities such as mud, sand, and plants in the raw water. The activated carbon filter 52 uses sintered activated carbon and can pre-filter the raw water to protect the reverse osmosis water inlet device, prevent fouling, and extend the service life of the reverse osmosis membrane.

[0046] The high-pressure pump 6 is used to pressurize the pre-treated raw water to reach the working pressure of the reverse osmosis membrane. The high-pressure pump 6 is a stainless steel plunger pump, and the motor used by the high-pressure pump is a brushless motor.

[0047] The reverse osmosis membrane of the reverse osmosis filtration assembly 7 includes a roll-type osmosis membrane and a carbon fiber module. The reverse osmosis membrane is a conventional reverse osmosis membrane with a recovery rate of 8%-15% and a desalination rate of ≥98%.

[0048] The piping system is a pipeline connecting various components and various valve components for controlling flow switches. The pipeline includes an inlet pipe, an outlet pipe, a wastewater pipe, a concentrate pipe, and a return pipe. The valve components include various three-way valves connecting the pipelines, a concentrate regulating valve 26, and a return regulating valve 27. Their function is to adjust according to different temperatures, different water sources, and the water quality of the produced water to achieve water quality that meets the requirements.

[0049] The salinity meter 21 is installed at the water production end and can perform real-time detection on the water quality of the produced water.

[0050] The present invention will be described in more detail below with reference to preferred examples.

[0051] like Figure 2 As shown, the water inlet 22 is connected to the filter screen through a hose, and the filter screen can filter large impurities such as mud, grass and trees in the raw water. The other end of the water inlet 22 is connected to the water inlet section of the self-priming pump 51 through a water suction pipe, and the water outlet section of the self-priming pump 51 is connected to two activated carbon filters 52 respectively after passing through a three-way valve. The wastewater ends of the two activated carbon filters 52 are connected to the wastewater port 23 through a three-way valve, and the water production ends of the two activated carbon filters 52 are connected to the water inlet section of the high-pressure pump 6 through a three-way valve. Among them, the self-priming pump 51 draws water from the source into the activated carbon filter 52 through the water suction pipe. The activated carbon filter 52 uses sintered activated carbon to pre-filter the raw water, and the pre-pre-filter component 5 is used to protect the reverse osmosis filter component 7 from fouling and blockage, thereby extending the service life of the reverse osmosis membrane.

[0052] The water outlet of the high-pressure pump 6 is connected to the water inlet of the two reverse osmosis filter components 7 through three-way valves. The high-pressure pump 6 pressurizes the pretreated raw water to reach the working pressure of the reverse osmosis membrane. The pressure gauge 29 is installed between the water outlet of the high-pressure pump 6 and the above-mentioned three-way valve to observe the water inlet pressure of the reverse osmosis filter component 7 in real time.

[0053] The concentrate ends of the two reverse osmosis filter components 7 are connected to the concentrate outlet 24 through a three-way valve to discharge the concentrate produced by the reverse osmosis filter components 7. The concentrate regulating valve 26 is installed between the concentrate outlet 24 and the three-way valve to adjust the water production and pressure.

[0054] The water production sections of the two reverse osmosis filter components 7 are connected to the water production port 25 through two three-way valves in series to discharge the filtered water produced by the reverse osmosis filter components 7. The salinity meter 21 is installed at the front end of the water production port 25 to monitor the water quality of the produced water in real time.

[0055] A three-way valve in the water production pipe is connected to the three-way valve in the water drawing pipe through a reflux regulating valve 27 , and the reflux regulating valve 27 is used to adjust the amount of reflux water.

[0056] Under high temperature conditions of 40°C, the desalination rate of the reverse osmosis filtration component 7 will decrease. In order to ensure that the water quality meets the drinking standard, measures to generate reflux are adopted at high temperatures. Under high temperature conditions, the water output will increase relatively. While ensuring a certain water output, the excess water will be returned to the water intake pipe. On the one hand, the salt content of the raw water is diluted, and on the other hand, part of the water is subjected to repeated cycles of reverse osmosis filtration.

[0057] The specific adjustment method is to start the equipment normally to produce water under high temperature conditions. When the produced water is stable, observe the water quality reading of the salinity meter 21. When the water quality does not meet the standard, slowly adjust the reflux regulating valve 27, and check the water quality, water volume and pressure of the produced water at the same time. The reverse osmosis pressure will drop during the reflux period. If the pressure gauge 29 is lower than 5.5MPa, the concentrated water regulating valve 26 can be manually adjusted to adjust the water pressure to between 5.5 and 6MPa. After the water pressure stabilizes, the produced water quality gradually reaches the drinking standard, and the operation of the portable reverse osmosis water inlet device under high temperature conditions is completed.
