Description

Technical Field

[0001] This utility model belongs to the field of seawater desalination technology and relates to a simple seawater desalination device. Background Technology

[0002] Seawater desalination is the process of producing fresh water by desalinating seawater, and it is a method for realizing the utilization of water resources. There are many different seawater desalination technologies, including reverse osmosis, multi-stage flash distillation, electrodialysis, and low-efficiency multi-effect distillation. However, since most of these technologies use complex equipment, have high operating costs, and require a large area, they are difficult to use in certain specific locations. Therefore, it is necessary to design a simple seawater desalination device that can reduce operating costs and be easily applied to certain specific locations. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simple seawater desalination device that is simple in structure, small in size, and can obtain fresh water under special circumstances.

[0004] This utility model is achieved through the following technical solution: a simple seawater desalination device, comprising a device body placed in seawater for desalination, the device body consisting of a casing and a vaporization membrane assembly. Inside the casing are independently arranged a first cavity, a second cavity, a third cavity, and a fourth cavity. The upper wall of the first cavity has an interface channel penetrating the casing, and a first interface is provided within the interface channel. The first cavity and the second cavity are connected by a connecting channel, on which a one-way valve is provided. The second cavity and the third cavity are arranged vertically and are interconnected. A vacuuming mechanism partially exposed within the third cavity is installed. The vaporization membrane assembly is installed within the fourth cavity. Multiple elongated holes penetrating the housing are provided on the outer side of the fourth cavity, and a second interface communicating with the fourth cavity and penetrating the housing is provided above the fourth cavity. A suspension mechanism and a rope hole fixing seat are respectively provided on the outside of the housing. After a rope is installed on the rope hole fixing seat, the second interface of the vaporization membrane assembly and the first interface of the first cavity are connected through a hose. When the vaporization membrane assembly of the device body is placed in seawater, the vaporization membrane assembly will not completely sink under the action of the suspension mechanism. At this time, through the combined action of the vacuum mechanism and the one-way air valve, the air in the second cavity and the first cavity is carried away and a negative pressure state is created. After the seawater enters the vaporization membrane assembly through the elongated holes of the housing and vaporizes, it enters the first cavity through the hose and the first interface for collection.

A push rod is also fixed at the upper end of the plug, with part of the push rod protruding outside the third cavity. By pushing and pulling the push rod up and down, the plug is driven to evacuate the second cavity below the third cavity. Under the combined action of the one-way valve, the air in the first cavity is carried away and becomes negative pressure.

[0006] Preferably, the suspension mechanism consists of a connecting block and an airbag. The connecting block is fixed to the outer surface of the housing, and an airbag is installed on the connecting block.

[0018] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1 As shown, a simple seawater desalination device includes a device body placed in seawater to desalinate seawater. The device body consists of a housing and a vaporization membrane assembly. Inside the housing, there are independent first chambers 2, 2 chambers 16, 3 chambers 17, and 4 chambers 30. The upper wall of the first chamber 2 has an interface channel 8 penetrating the housing 1, and a first interface 9 is provided in the interface channel 8. The first chamber 2 and the second chamber 16 are connected by a connecting channel 14, and a one-way valve 15 is provided on the connecting channel 14. The second chamber 16 and the third chamber 17 are arranged vertically and are interconnected. A vacuuming mechanism partially exposed in the third chamber 17 is installed. The fourth chamber 30 is equipped with a vaporization membrane assembly 27. A fourth chamber 30 is located on the outer side of the housing 1. The device has multiple elongated holes 29 penetrating the housing 1, and a second interface 7, which communicates with the fourth cavity 30 and penetrates the housing 1, is provided above the fourth cavity 30. The housing 1 is equipped with a suspension mechanism and a rope hole fixing seat 26. After a rope (not shown in the figure) is installed on the rope hole fixing seat 26, the second interface 7 of the vaporization membrane assembly and the first interface 9 of the first cavity 2 are connected through a flexible hose (not shown in the figure). The vaporization membrane assembly 27 of the device body is placed in seawater. Under the action of the suspension mechanism, the vaporization membrane assembly 27 will not sink completely. At this time, through the combined action of the vacuum mechanism and the one-way air valve 15, the air in the second cavity 16 and the first cavity 2 is carried away and a negative pressure is created. The seawater enters the vaporization membrane assembly 27 through the elongated holes 29 of the housing 1, vaporizes, and then enters the first cavity 2 through the flexible hose and the first interface 9 for collection.

[0019] like Figure 2-3As shown, the vacuuming mechanism consists of a plug 21 and a push rod 18. The plug 21 is installed in the third cavity 17 and its area matches that of the third cavity 17. The plug 21 is provided with an air hole 22, and a plug 20 is installed in the air hole 22. The plug 20 is rotatably connected to a fixing block 19 provided on the plug 21 to ensure that the plug 21 can move up and down in the third cavity 17. A push rod 18 is also fixed at the upper end of the plug 21. Part of the push rod 18 is exposed outside the third cavity 17. By pushing and pulling the push rod 18 up and down, the plug 21 is driven to evacuate the second cavity 16 below the third cavity 17. Under the joint action of the one-way valve 15, the air in the first cavity 2 is carried away and becomes negative pressure.

[0020] The suspension mechanism consists of a connecting block 24 and an airbag 25. The connecting block 24 is fixed to the outer surface of the housing, and the airbag 25 is installed on the connecting block 24. The airbag 25 ensures that the seawater desalination device will not completely sink when placed in seawater.

[0021] Two pressure channels 10 and water outlet channels 12 are respectively provided on the front of the first cavity 2 on the housing 1. The pressure channel 10 is equipped with a pressure gauge 11, and the water outlet channel 12 is equipped with a sealing plug 13. When the seawater collected in the first cavity 2 after being vaporized by the vaporization membrane assembly is desalinated, the sealing plug 13 is opened to allow the fresh water in the first cavity 2 to flow out.

[0022] A base plate 3 is detachably mounted on the bottom surface of the housing 1. A vaporization film assembly 27, located inside the housing 1, is placed on the base plate 3. A pulley seat 4 is mounted directly below the base plate 3, and a pulley 5 is mounted on the pulley seat 4. Cover plates 6 are respectively installed at the upper and lower ends of the vaporization film assembly 27 inside the housing. A first interface 7 is installed on the upper cover plate 6. The vaporization film assembly 27 consists of a component housing 23 and a vaporization film group 28 installed inside the component housing 23. The vaporization film group 28 is composed of multiple film sheets bonded together.

[0023] The working principle and process of this utility model are as follows:

[0024] The vaporization membrane module of this device is formed by bonding membrane sheets together. Except for the openings at the top and bottom ends, its interior is conductive and does not contact the outside. The membrane sheets are either conventional membrane sheets or modified membrane sheets. Their surfaces are covered with densely packed tiny pores. Due to the physical properties of the membrane sheets, the evaporated water molecules can more easily pass through the pores in the membrane sheets. Under the action of negative pressure, the vaporization membrane module immersed in seawater can more easily vaporize the water molecules in the seawater, thereby passing through the pores on the membrane surface and collecting in the first chamber.

[0025] After binding the rope to the rope hole fixing seat 26 and connecting the second interface 7 to the first interface 9 with the hose, the vaporization membrane assembly 27 is placed in seawater. Under the buoyancy of the airbag 25, the vaporization membrane assembly 27 will not sink completely, making it easy to recover. At this time, push the push rod 18 up and down. Under the action of the one-way air valve 15 and the plug 20, the air in the first chamber 2 is carried away and a negative pressure state is created. The seawater adheres to the surface of the vaporization membrane assembly 28 after passing through the long hole 29 in the component shell 23. After the water molecules in the seawater vaporize, they are collected in the first chamber 2 through the small holes of the membrane. After a certain amount is collected, the sealing plug 13 can be opened to allow the fresh water in the first chamber 2 to flow out.

[0026] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
