Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a nanofiber membrane evaporation treatment device for high-concentration salt water. Background Technology

[0002] Traditional seawater cannot be used directly due to its high salinity, corrosiveness, ecological risks, and high treatment costs. Traditional water purification equipment is mostly cartridge-type filters, which cannot treat high-concentration brine or corrosive industrial wastewater.

[0003] Existing high-salinity water evaporation treatment or seawater desalination equipment uses thermal energy to evaporate water from high-salinity wastewater, thereby separating salt from water and facilitating the use of high-salinity water or seawater.

[0004] However, existing devices rely on mains power, and in energy-deficient scenarios, they cannot handle high-concentration salt water, seawater, and corrosive liquids, thus reducing their adaptability. Utility Model Content

[0005] The purpose of this invention is to provide a nanofiber membrane evaporation treatment device for high-concentration brine, which aims to solve the problem that existing devices rely on mains power and cannot handle high-concentration brine, seawater and corrosive liquids in energy-deficient scenarios, thus reducing the adaptability of the device.

[0006] To achieve the above objectives, this utility model provides a nanofiber membrane evaporation treatment device for high-concentration saline solutions, comprising a movable support, a telescopic support, a solar collector, a nanofiber membrane evaporation module, a raw liquid collection tank, a purified water pipe, and connecting fittings. The telescopic support is mounted on the movable support and located on one side of the movable support. The solar collector is mounted on the telescopic support and located on one side of the telescopic support. The nanofiber membrane evaporation module is mounted on the movable support and located on one side of the movable support. The raw liquid collection tank is mounted on the nanofiber membrane evaporation module and located on one side of the nanofiber membrane evaporation module. The purified water pipe is connected to the nanofiber membrane evaporation module. The connecting fittings are mounted on the solar collector and connected to both the nanofiber membrane evaporation module and the raw liquid collection tank.

[0007] The connecting pipes include a circulating water inlet pipe and a circulating water outlet pipe. The circulating water inlet pipe is connected to the solar collector and the raw liquid collection box, respectively. The circulating water outlet pipe is connected to the solar collector and the nanofiber membrane evaporation module, respectively.

[0008] The nanofiber membrane evaporation treatment device for high-concentration brine also includes a fixed support, which is fixedly connected to the movable support and located on one side of the movable support.

[0009] The nanofiber membrane evaporation treatment device for high-concentration brine also includes a solar collector plate with folded louvers, which are disposed on the solar collector plate and located on one side of the solar collector plate.

[0010] The nanofiber membrane evaporation treatment device for high-concentration brine also includes a concentrate recovery tank, which is installed on the nanofiber membrane evaporation module and located on one side of the nanofiber membrane evaporation module.

[0011] This invention discloses a nanofiber membrane evaporation treatment device for high-concentration brine. Water from the raw liquid collection tank flows through connecting pipes into the solar collector under gravity, where it is heated and supplied to the nanofiber membrane evaporation module. This creates a closed hot water circulation system between the solar collector and the nanofiber membrane evaporation module, achieving efficient heat transfer. The nanofiber membrane evaporation module uses a nanofiber membrane as the core evaporation unit. Driven by the heat supplied by the solar collector, it achieves efficient evaporation and separation of the liquid. The treated water vapor condenses and is discharged through the purified water outlet, achieving resource recovery. Thus, the solar collector and the nanofiber membrane evaporation module enable the treatment and purification of high-concentration brine, seawater, and corrosive liquids in energy-scarce environments, relying on solar energy, thereby improving the adaptability of the device.

In energy-scarce scenarios, existing devices cannot handle high-concentration brine, seawater, and corrosive liquids, thus reducing their adaptability. Therefore, this solution can be used in situations requiring liquid purification in energy-scarce environments.

[0020] In this embodiment, all structures are mounted on the same mobile support 101 system. The bottom of the mobile support 101 is equipped with casters and a handle, which facilitates the pushing and positioning of the device in the field.

[0021] The telescopic support 102 is mounted on the movable support 101 and located on one side of the movable support 101. The solar collector 103 is mounted on the telescopic support 102 and located on one side of the telescopic support 102. The nanofiber membrane evaporation module 104 is mounted on the movable support 101 and located on one side of the movable support 101. The raw liquid collection tank 105 is mounted on the nanofiber membrane evaporation module 104 and located on one side of the nanofiber membrane evaporation module 104. The water purification pipe 106 is connected to the nanofiber membrane evaporation module. Module 104 is connected, and the connecting pipe is set on the solar collector plate 103 and connected to the nanofiber membrane evaporation module 104 and the raw liquid collection box 105. The movable support 101 is equipped with four universal wheels. The movable support 101 can be moved by hand or extended to be moved by electric drive. Thus, the movable support 101 can facilitate the flexible deployment and movement of the whole device in different places. The solar collector plate 103 is installed on the telescopic support 102. The solar collector plate 103 has a flat plate structure and a heat collection pipe and a water cavity on the back. The solar collector 103 forms a closed water circuit with the nanofiber membrane evaporation module 104 through the connecting pipe. The hot water inside is continuously circulated by the pump, keeping the nanofiber membrane evaporation module 104 at a relatively high temperature range (40–70℃), promoting liquid evaporation on the membrane surface. The nanofiber membrane evaporation module 104 is located in the center of the device, and the membrane sheet composed of high porosity, hydrophobic nanofiber membrane serves as the core separation structure. It is installed in a removable and replaceable membrane frame. When the raw liquid is heated to the set temperature, the nanofiber membrane evaporation module 104 starts the evaporation process. Liquid vapor molecules form on the membrane surface and are transported to the other side through the membrane pores. After condensation, the vapor is collected as fresh water and discharged from the purified water outlet at the front end of the system. When the raw liquid is heated to the set temperature by the solar collector 103, the nanofiber membrane evaporation module 104 starts the evaporation process. Liquid vapor molecules form on the membrane surface and are transported to the other side through the membrane pores. After condensation, the vapor is collected as fresh water and discharged from the purified water pipe 106 outlet at the front end of the system. The entire system's support structure adopts a frame design. The bottom of the movable bracket 101 is equipped with four universal wheels and brake locks for easy pushing and fixing. When the system is in operation, the solar collector 103 can be extended to its maximum angle. The angle of the telescopic bracket 102 can be adjusted to adapt to different solar irradiation conditions. The raw liquid collection tank 105 is an integrated liquid tank, fixedly installed on the upper outer side of the nanofiber membrane evaporation module 104, used to store high-salt or brackish water and other liquids that need to be treated.The raw liquid collection tank 105 has an opening and a sealing cap at the top for easy injection of raw liquid and dust prevention. At the bottom, a connecting pipe allows liquid to be transported to the solar collector plate 103. This connecting pipe is mounted on the solar collector plate 103 and connects to the nanofiber membrane evaporation module 104 and the raw liquid collection tank 105. This connection allows water to flow from the raw liquid collection tank 105 into the solar collector plate 103 under gravity, where it is heated and supplied to the nanofiber membrane evaporation module 104. 4. The solar collector 103 and the nanofiber membrane evaporation module 104 form a closed hot water circulation system, achieving efficient heat transfer. The nanofiber membrane evaporation module 104 uses a nanofiber membrane as the core evaporation treatment unit. Driven by the heat supplied by the solar collector 103, it achieves efficient evaporation and separation of liquid. After the treated water vapor is condensed, it is discharged through the outlet of the purified water pipe 106, realizing resource recovery. Thus, the solar collector 103 and the nanofiber membrane evaporation module 104 can treat and purify high-concentration salt water, seawater and corrosive liquids in energy-deficient scenarios by relying on solar energy, thereby improving the adaptability of the device.

[0022] Secondly, the circulating water inlet pipe 110 is connected to the solar collector plate 103 and the raw liquid collection tank 105 respectively; the circulating water outlet pipe 111 is connected to the solar collector plate 103 and the nanofiber membrane evaporation module 104 respectively. The circulating water inlet pipe 110 is connected to the solar collector plate 103 and the raw liquid collection tank 105 respectively, so that the raw liquid in the raw liquid collection tank 105 can flow into the solar collector plate 103 under the action of gravity through the circulating water inlet pipe 110. The circulating water outlet pipe 111 is connected to the solar collector plate 103 and the nanofiber membrane evaporation module 104 respectively, so that the liquid in the solar collector plate 103 can flow into the nanofiber membrane evaporation module 104 under the action of gravity through the circulating water outlet pipe 111.

[0023] Meanwhile, the fixed bracket 107 is fixedly connected to the movable bracket 101 and is located on one side of the movable bracket 101. The fixed bracket 107 is welded to the movable bracket 101. The fixed bracket 107 can be used to store and fix the shrunken original liquid collection box 105.

[0024] In addition, the solar collector panel folding louvers 108 are disposed on the solar collector panel 103 and located on one side of the solar collector panel 103. The solar collector panel folding louvers are provided on one side of the solar collector panel 103. When the solar collector panel folding louvers are unfolded, the heat collection area can be expanded. When stored, they can be folded together to enhance portability. In the non-working state, the solar collector panel 103 and the solar collector panel folding louvers 108 can be folded together, and the system as a whole has a rectangular storage shape, which is convenient for transportation and storage.

[0025] Finally, the concentrate recovery tank 109 is installed on the nanofiber membrane evaporation module 104 and located on one side of the nanofiber membrane evaporation module 104. The concentrate recovery tank 109 is connected to the base of the nanofiber membrane evaporation module 104. The concentrate recovery tank 109 is used to collect the concentrate that has not been evaporated.

[0026] When using the nanofiber membrane evaporation treatment device for high-concentration brine according to this embodiment, water from the raw liquid collection tank 105 flows into the solar collector plate 103 through connecting pipes under the action of gravity, and the water is heated and supplied to the nanofiber membrane evaporation module 104. This forms a closed hot water circulation system between the solar collector plate 103 and the nanofiber membrane evaporation module 104, achieving efficient heat transfer. The nanofiber membrane evaporation module 104 uses a nanofiber membrane as the core evaporation treatment unit. Driven by the heat supplied by the solar collector plate 103, it achieves efficient evaporation and separation of liquid. After the treated water vapor is condensed, it is discharged through the outlet of the purified water pipe 106, realizing resource recovery. Thus, the solar collector plate 103 and the nanofiber membrane evaporation module 104 can treat and purify high-concentration brine, seawater and corrosive liquids by relying on solar energy in energy-deficient scenarios, thereby improving the adaptability of the device.
