Description

Technical Field

[0001] The present invention belongs to the technical field of water production, and particularly relates to an integrated water production device and a water production method thereof. Background Art

[0002] The functions of traditional water production equipment are usually relatively single. Processes such as filtration, evaporation, and condensation are often independent of each other. The equipment is scattered and occupies a large amount of space. The connection between different processes is not smooth enough. The process of seawater from filtration to evaporation and then to condensation and water storage is cumbersome, not only inefficient, but also prone to failures due to the increase in operation links, and the maintenance difficulty is relatively large.

[0003] Some water production devices with the concept of integration perform poorly in the seawater filtration link. Seawater contains a large amount of impurities, microorganisms, and salts. General filtration mechanisms are difficult to completely remove impurities, resulting in interference in subsequent evaporation and condensation processes, affecting the quality of fresh water and the service life of the equipment. There are also deficiencies in the design of the evaporation mechanism. The evaporation efficiency of seawater is not high, and the energy utilization is not sufficient. For example, in a common planar evaporation structure, the contact area between seawater and heat is small and the time is short, and a large amount of heat is dissipated without being effectively utilized. In terms of condensation and water storage, the condensation effect is not ideal, the steam condensation is not sufficient, resulting in waste of water resources, and the design of the water storage space is unreasonable, making it difficult to meet the water use requirements in different scenarios. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an integrated water production device and a water production method thereof, which integrate functions such as filtration, evaporation, and condensation, realize an efficient, energy-saving, and stable water production process, and meet diverse water use requirements.

[0005] To solve the above technical problem, the technical solution adopted by the present invention is: An integrated water production device includes a filtration and separation mechanism, a seawater storage tank cavity, an evaporation mechanism, and a condensation and water storage mechanism; The seawater storage tank cavity is connected to the pump body inlet through pipeline two, the pump body outlet is connected to pipeline one, a flow controller is provided on pipeline one, and the outlet of pipeline one transports seawater to the seawater desalination layer at the top of the evaporation mechanism; The filtration and separation mechanism is arranged on the upper part of the seawater storage tank cavity. After the filtration and separation mechanism performs secondary filtration on seawater, the filtered seawater is stored in the seawater storage tank cavity; The seawater desalination layer is spiral. The pump body transports seawater to the top of the evaporation mechanism and enters the seawater desalination layer. The seawater spirals to the bottom of the evaporation mechanism. The sea salt after seawater evaporation passes through the seawater desalination layer and is washed through the brine separation membrane by the flowing seawater, and finally reaches the sea salt storage tank cavity; The unevaporated seawater continues to circulate. A steam-water separation membrane is attached to the side of the evaporation mechanism, and the condensation mechanism outside the steam-water separation membrane condenses the flowing steam into fresh water and stores it in the condensation water storage area.

[0006] Preferably, an LED lamp cap is provided on the evaporation mechanism, and the lower part of the evaporation mechanism is separated from the seawater storage tank cavity by a bottom shell and a brine separation membrane; A pipe 1 is connected between the evaporation layer inlet at the top of the evaporation mechanism and the pump body. After seawater flows in through the pipe 2, it is transported to the pipe 1 by the pump body and flows into the seawater desalination layer, and the flow controller ensures that the seawater in each layer is at the height of the seawater desalination layer in the seawater desalination layer; The outer wall of each seawater desalination layer is surrounded by a steam-water separation membrane between the bottom ends of the upper seawater desalination layer.

[0007] Preferably, the inside of the LED lamp cap contains a cover plate, and the cover plate is covered with a light source.

[0008] Preferably, the outer shell surrounds the filtration and separation mechanism. The bottom end of the outer shell is a seawater storage tank cavity, and the outer shell is made of a light-concentrating material.

[0009] Preferably, the inside of the filtration and separation mechanism is divided into four filtration layers, and each layer is provided with multiple columns of pores. Quartz sand is filled in the pores of the upper filtration layer and the upper second filtration layer to form a quartz sand filtration layer. Activated carbon is filled in the pores of the lower filtration layer and the lower second filtration layer to form an activated carbon filtration layer. After seawater passes through the quartz sand filtration layer and the activated carbon filtration layer, it flows into the seawater storage tank cavity.

[0010] Preferably, a filtration and separation mechanism is provided in the upper part of the seawater storage tank cavity and is surrounded by the outer shell. The middle part is separated by a sea salt storage tank cavity, and the filtered seawater at the bottom is transported to the pump body through the pipe 2.

[0011] Preferably, the periphery and the bottom of the sea salt storage tank cavity are isolated from the seawater storage tank cavity. The upper end of the sea salt storage tank cavity is connected to the bottom end of the evaporation mechanism and is separated from the outlet of the evaporation mechanism by a water-salt separation membrane. The evaporated sea salt is washed into the sea salt storage tank cavity by the seawater flowing through the seawater desalination layer in the evaporation mechanism.

[0012] Preferably, the outside of the condensation and water storage mechanism is the filtration and separation mechanism. The inside of the condensation and water storage mechanism is connected to the condensation sheet. The condensation and water storage mechanism is used to condense the water vapor evaporated in the evaporation mechanism, and the condensed fresh water flows into the condensation water storage area.

[0013] Preferably, the outer shell is made of a light-concentrating material; The light source is a green LED light, and when the water production process is carried out, the evaporation mechanism can be completely wrapped under the light source; The overall seawater desalination layer is a transparent glass channel and adopts a spiral staircase structure, so that when the seawater evaporates, the flow rate can be reduced and it can fully contact with the light source; The seawater desalination layer of the evaporation mechanism is provided with a hydrogel material, and the height of the hydrogel always remains at 1 / 3 of the height of the seawater desalination layer.

[0014] A water production method of an integrated water production device includes the following steps: Step 1: Seawater enters the filtration and separation mechanism through an external pipeline after preliminary filtration and then undergoes secondary filtration. Step 2: After flowing into the filtration and separation mechanism, the seawater is first separated in the upper first filtration layer and the upper second filtration layer, and then enters the lower first filtration layer and the lower second filtration layer for filtration and enters the seawater storage cavity. Step 3: Seawater is transported from the seawater storage tank cavity to the pump body through pipeline two, and the pump body then transports the seawater to the top seawater desalination layer of the evaporation mechanism through pipeline one for evaporation. A flow controller is attached to pipeline one to ensure that the height of the continuously flowing seawater in the seawater desalination layer is 2 / 3 of the evaporation layer. Step 4: The water vapor evaporated from the seawater in the seawater desalination layer flows to the periphery of the evaporation layer, passes through the steam-water separation membrane, enters the condensation and water storage mechanism, and condenses into fresh water on the condensation sheet and flows into the condensation water storage area. The fresh water in the condensation water storage area is controlled for access to and from the outside through pipeline valves. Step 5: After the seawater evaporates into water vapor and enters the condensation mechanism, sea salt remains on the surface of the evaporation layer of the evaporation mechanism. Since the seawater continuously flows on the evaporation layer, the sea salt left by evaporation is washed along the spiral seawater desalination layer to the pores where the water-salt separation membrane is located at the bottom of the seawater desalination layer and enters the sea salt storage tank cavity, while the seawater that has not evaporated in the evaporation layer enters the seawater storage tank cavity to complete the next cycle.

[0015] The present invention can achieve the following beneficial effects: 1. The inside of the filtration and separation mechanism is divided into four filtration layers. The upper first and upper second filtration layers are filled with quartz sand, and the lower first and lower second filtration layers are filled with activated carbon. This design can deeply purify seawater. The quartz sand can effectively intercept large particle impurities in seawater, and the activated carbon uses its adsorption property to remove tiny particles, organic substances and some harmful ions, greatly improving the purity of the seawater entering the subsequent process, ensuring the water quality of the finally produced fresh water, reducing the damage of impurities to the evaporation and condensation mechanisms, and extending the overall service life of the equipment.

[0016] 2. The seawater first undergoes preliminary filtration and then enters this filtration and separation mechanism for secondary filtration. The double filtration mechanism further ensures the cleanliness of the seawater entering the seawater storage tank cavity, laying a good foundation for the subsequent water production link. Compared with single filtration, it can remove impurities more thoroughly and improve the stability of water production.

[0017] 3. The desalination layer is spiral-shaped. The pump body transports seawater to the top of the evaporation mechanism and enters the desalination layer. The seawater spirals to the bottom of the evaporation mechanism. This unique spiral structure greatly increases the flow path and time of seawater during the evaporation process, allowing seawater to be more fully in contact with heat and improve evaporation efficiency. At the same time, compared with the traditional flat evaporation structure, the spiral design increases the contact area between seawater and the evaporation environment. Under the same energy consumption, more seawater can be evaporated, reducing the energy consumption cost per unit of fresh water.

[0018] 4. A flow controller is installed on the pipeline to ensure that each layer of seawater is at 2 / 3 of the height of the evaporation layer. By accurately controlling the seawater flow rate and maintaining a reasonable liquid level of seawater in the evaporation layer, seawater can continuously and stably receive heat during the evaporation process, avoiding reduced evaporation efficiency or energy waste due to too much or too little seawater, further optimizing the evaporation process and improving energy utilization efficiency.

[0019] 5. The outer shell is made of focusing material, and the light source inside the LED lamp end cap is green LED light. When the water production process is in progress, the evaporation mechanism is completely wrapped in the light source. The focusing material can focus the light on the evaporation mechanism to enhance heat transfer. The green LED light provides suitable lighting conditions to promote seawater evaporation. Without increasing a lot of energy consumption, it significantly improves the evaporation speed and efficiency, and achieves energy-saving water production.

[0020] 6. The condensation water storage mechanism is connected to the condensation sheet, which can efficiently condense the water vapor evaporated from the evaporation mechanism. A steam-water separation membrane is attached to the side of the evaporation mechanism, which can effectively separate steam from unevaporated seawater, allowing pure water vapor to enter the condensation water storage mechanism and quickly condense into fresh water under the action of the condensation sheet, flowing into the condensation water storage area, reducing steam loss and improving fresh water collection efficiency.

[0021] 7. The condensation water storage area of ​​the condensation water storage mechanism is connected to the outside world through pipeline valves to control the storage and access of fresh water. This design facilitates the flexible use of fresh water according to actual water demand, while preventing external impurities from entering the water storage area, ensuring the safety of fresh water storage and the stability of water quality.

[0022] 8. After the seawater evaporates, the sea salt passes through the desalination layer and is washed by the flowing seawater through the pores surrounded by the salt water separation membrane, and finally reaches the sea salt storage tank cavity. The seawater continues to flow in the evaporation layer, and naturally washes the sea salt left by evaporation along the spiral evaporation layer to the sea salt storage tank cavity at the bottom. No additional manual operation is required to collect it, which reduces labor costs. The collection process is efficient and convenient, ensuring that the sea salt in the evaporation mechanism is cleaned up in time without affecting the efficiency of seawater evaporation.

[0023] 9. The periphery and bottom of the sea salt storage tank cavity are isolated from the sea water storage tank cavity, the upper end is connected to the bottom end of the evaporation mechanism, and the outlet of the evaporation mechanism is separated by a water-salt separation membrane. This design can not only ensure the smooth collection and storage of sea salt, but also avoid the mixing of sea salt with the sea water in the sea water storage tank cavity, ensure the purity of sea salt collection, and maintain the normal circulation of the sea water in the sea water storage tank cavity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The preferred solution is as Figures 1 to 4 shown. An integrated water production device includes: LED lamp end cap 1, outer shell 2, filtration and separation mechanism 3, sea water storage tank cavity 8, evaporation mechanism 5, condensation and water storage mechanism 4, sea salt storage tank cavity 72; The inlet of the pump body 63 is connected to the sea water storage tank cavity 8 through the pipeline 2 64, the outlet of the pump body 63 is connected to the pipeline 1 61, the pipeline 1 61 is attached with a flow controller 62, and the outlet of the pipeline 1 61 conveys sea water to the top sea water desalination layer 52 of the evaporation mechanism 5; After the filtration and separation mechanism 3 filters the sea water twice, the filtered sea water is stored in the sea water storage tank cavity 8, the pump body 63 conveys the sea water to the top end of the evaporation mechanism 5 and enters the sea water desalination layer 52. The sea water desalination layer 52 is spiral to the bottom end of the evaporation mechanism 5. The sea salt after the evaporation of the sea water is washed by the flowing sea water through the pores 71 surrounded by the brine separation membrane to the sea salt storage tank cavity 72. The unevaporated sea water continues to circulate. The evaporation mechanism 5 is attached with a steam-water separation membrane 9 on the side, and outside the steam-water separation membrane 9 is a condensation mechanism 5 that condenses the flowing steam into fresh water and stores it in the cavity 43; The interior of the LED lamp end cap 1 contains a cover plate, and the light source 11 is covered on the cover plate; The outer housing 2 surrounds the filtration and separation mechanism. The bottom end is a seawater storage tank cavity 8, and the outer housing is made of a light-concentrating material; The outer part of the filtration and separation mechanism 3 is surrounded by the outer housing 2. The interior is divided into four filtration layers, and each layer is provided with multiple columns of pores. Quartz sand is filled in the pores of the upper filtration layer 31 and the upper second filtration layer 32, which is a quartz sand filtration layer. Activated carbon is filled in the pores of the lower filtration layer 33 and the lower second filtration layer 34, which is an activated carbon filtration layer. Seawater flows into the seawater storage tank cavity 8 after passing through the quartz sand filtration layer and the activated carbon filtration layer; The seawater storage tank cavity 8 is above the filtration and separation mechanism 3 and is surrounded by the outer housing 2. The middle part is separated by a sea salt storage tank cavity 72. The filtered seawater at the bottom is transported to the pump body 63 through a second pipeline 64; The periphery and bottom of the sea salt storage tank cavity 72 are isolated from the seawater storage tank cavity 8. The upper end is connected to the bottom end of the evaporation mechanism 5, and is separated from the outlet of the evaporation mechanism 5 by a water-salt separation membrane 71. The evaporated sea salt is washed into the sea salt storage tank cavity 72 by the seawater flowing through the seawater desalination layer 52 in the evaporation mechanism; The evaporation mechanism 5 is connected to the LED lamp end cap 1 at the top, and the lower part is separated from the seawater storage tank cavity 8 by a bottom housing and a brine separation membrane 71. The top evaporation layer inlet is connected to the pump body 63 through a first pipeline 61. After seawater flows in through the second pipeline 64, it continuously flows through the seawater desalination layer 52, and the flow controller 62 ensures that the seawater in each layer is at 2 / 3 of the height of the outer housing 2 of the seawater desalination layer 52 in the seawater desalination layer 52. The space between the outer housing 2 and the upper part is surrounded by a steam-water separation membrane 9. The water vapor evaporated from the seawater on the seawater desalination layer 52 in the evaporation mechanism 5 irradiated by the LED light 11 enters the condensation water storage mechanism 4 through the steam-water separation membrane 9 and condenses into fresh water on the condensation sheet 42 and flows into the fresh water storage area 43; The periphery of the condensation water storage mechanism 4 is the filtration and separation mechanism 3, and the interior is connected to the condensation sheet 42 to condense the water vapor evaporated in the evaporation mechanism 5. The condensed fresh water flows into the condensation water storage mechanism 43.

[0027] 2. The peripheral housing 2 is made of a light-concentrating material, and the light source 11 is a green LED light. When the water production process is carried out, the evaporation mechanism 5 can be completely wrapped under the light source 11. The seawater desalination layer 52 is an overall transparent glass channel and adopts a spiral stepped structure, so that when the seawater evaporates, the flow rate can be reduced and it can be in full contact with the light source 11, thereby improving the evaporation efficiency. The number of stepped winding turns of the seawater desalination layer 52 can be increased or decreased according to the actual working conditions. When the water production demand is large, the number of stepped winding turns can be increased and the green LED light source 11 can be additionally arranged on the bottom surface of each layer of the seawater desalination layer 52 of the device, so as to increase the evaporation amount. The overall size of the new water production device and each liquid storage space can be increased or decreased according to the actual situation. 3. The seawater desalination layer 52 of the evaporation mechanism 5 is provided with a hydrogel material, and the height of the hydrogel always remains at 1 / 3 of the height of the seawater desalination layer 52. When the hydrogel material combines with water, it will form a strong absorbent, increasing the absorption of light molecules and thus improving the seawater evaporation efficiency. 4. The overall model design of the new water production device is conducive to actual use. In the external environment, the preliminarily filtered seawater is directly sleeved on the top of the device through a water pipe and a pipe shell, and then the seawater directly enters the filtration and separation device 3 from the external pipeline. A novel integrated water production device and a water production method thereof are characterized by including the following steps: Step 1: The seawater enters the filtration and separation mechanism 3 from the external pipeline after preliminary filtration and then undergoes secondary filtration. Step 2: After the seawater flows into the filtration and separation mechanism, it is first separated in the quartz sand filtration layers 31 and 32, and then enters the activated carbon filtration layers 33 and 34 for filtration and enters the seawater storage cavity 8. Step 3: The seawater is transported from the seawater storage tank cavity 8 to the pump body 63 through the second pipeline 63, and the pump body 8 then transports the seawater to the top seawater desalination layer 52 of the evaporation mechanism 3 through the first pipeline 61 for evaporation. A flow controller 62 is attached to the first pipeline to ensure that the height of the continuously flowing seawater in the seawater desalination layer 52 is 2 / 3 of the evaporation layer. Step 4: The water vapor evaporated from the seawater in the seawater desalination layer 52 flows to the periphery of the evaporation layer and passes through the steam-water separation membrane 9 into the condensation and water storage mechanism 4, and condenses into fresh water on the condensation sheet and flows into the condensation and water storage area 43, where the condensation and water storage area is controlled to access fresh water through a pipeline valve. Step 5: The seawater evaporates into water vapor and enters the condensation mechanism, leaving sea salt on the surface of the evaporation layer of the evaporation mechanism 5. Since the seawater continuously flows on the evaporation layer, the sea salt left by evaporation is washed along the spiral seawater desalination layer 52 into the pores where the water-salt separation membrane is located at the bottom of the seawater desalination layer 52 and enters the sea salt storage cavity, while the seawater that has not evaporated in the evaporation layer enters the seawater storage cavity to complete the next cycle.

[0028] The advantages of the present invention are as follows: 1. An integrated new water-making device is not only convenient to carry, but also greatly shortens the economic cost and space size in all aspects. It can be directly connected to the seawater pipeline for fresh water preparation during use; 2. The evaporation layer in an integrated new water-making device is a spiral stepped structure made of transparent glass, which reduces the flow rate of seawater in the channel, increases the evaporation area, and thus improves the seawater evaporation efficiency; 3. Compared with traditional seawater desalination methods (such as distillation method, reverse osmosis method), an integrated new water-making device and its water-making method can directly achieve seawater evaporation through light without heating, thereby improving the seawater desalination efficiency and reducing energy consumption, and also greatly reducing the seawater desalination cost; 4. A hydrogel material is added to an integrated new water-making device and its water-making method, which increases the absorption of light, thereby improving the seawater evaporation efficiency.
