Abstract
Description
Technical Field
[0001] The utility model belongs to the field of seawater application, in particular to a novel seawater purification device. Background Art
[0002] Seawater purification refers to the removal of impurities (such as salt, microorganisms and pollutants) from seawater to make it fresh water that can be used for water supply, irrigation and other purposes. Seawater purification is a way to solve the problem of freshwater shortage, especially in areas or islands where there is a lack of available fresh water.
[0003] Common seawater purification technologies and methods include seawater desalination membrane technology, distillation technology, seawater electrolysis, solar seawater purification, seawater condensation, chemical purification, and biological seawater purification.
[0004] (1) Seawater desalination membrane technology: This is one of the most commonly used seawater purification technologies. The most common method is reverse osmosis, which separates water from salt and impurities under the pressure of seawater through a semi-permeable membrane.
[0005] (2) Distillation technology: This method heats seawater to boiling point and then condenses the steam into fresh water. Distillation can effectively remove salt and pollutants, but it consumes a lot of energy.
[0006] (3) Electrolysis of seawater: This method separates ions from seawater through an electrolysis process to produce fresh water. This requires the use of electrolysis equipment and a source of electricity.
[0007] (4) Solar water purification: Using solar energy to purify seawater is a sustainable and environmentally friendly method. Solar energy can provide energy, for example, to drive distillation equipment.
[0008] (5) Seawater condensation: This method uses the low temperature of the environment to condense the steam in seawater and then collect fresh water.
[0009] (6) Chemical purification: includes methods that react with chemical substances (such as polymers or chemical agents) to adsorb or precipitate impurities.
[0010] (7) Biological seawater purification: using biotechnology, such as using microorganisms or plants to degrade or absorb pollutants in seawater.
[0011] However, distillation purification technology currently relies mainly on solar thermal energy or other waste heat for heating, and has relatively high requirements for weather or waste heat. Utility Model Content
[0012] In order to effectively solve the problem of unstable heat source in seawater distillation purification, the utility model provides a novel seawater purification device, which utilizes wind power to drive an electrode steam boiler to provide a stable heat source for seawater distillation purification.
[0013] The utility model adopts the following technical solutions to solve the above problems:
[0014] A novel seawater purification device includes a purification device system, which is arranged near a wind power station. The purification device system includes an electrode steam boiler, which is connected to the wind power station. The electrode steam boiler is respectively connected to a second water treatment device and a third water treatment device. The third water treatment device pumps water from seawater through a water pump. The third water treatment device is connected to a distilled water tank, which is connected to the second water treatment device.
[0015] Further, the distilled water tank may be connected to a user.
[0016] Furthermore, the second water treatment device is a deaerator.
[0017] Furthermore, the third water treatment device is a multi-stage distillation and filtration device.
[0018] Furthermore, the water pump is also connected to a first water treatment device, and the first water treatment device is connected to a second water treatment device.
[0019] Furthermore, the first water treatment device includes a softening water system and a reverse osmosis filtration system.
[0020] Furthermore, the third water treatment device can be connected to a plurality of distilled water tanks.
[0021] Furthermore, a plurality of the distilled water tanks may be connected to a user.
[0022] The beneficial effects of the utility model are:
[0023] 1. By setting up an offshore wind power station near an offshore wind power station or at a seashore with sufficient wind power, the electricity generated by wind power is used to drive the electrode steam boiler to provide a heat source for seawater distillation. Not only is the water production large, but it is generally not easily affected by the weather;
[0024] 2. This device is driven by electricity generated by wind power. Since the wind resources are abundant at the seaside, it is more stable than solar thermal energy. At the same time, the temperature of the steam generated is constant, which makes the distillation system work more stably and the quality of the filtered seawater is better;
[0025] 3. When the device is operated for the first time, a portion of seawater needs to be filtered through the first water treatment device. The first water treatment device includes a softening water system and a reverse osmosis filtration system, which are used to produce pure water required for the operation of the electrode steam boiler, effectively remove impurities in the seawater, reduce the impurities entering the electrode steam boiler and affecting its performance, and ensure the stable operation of the electrode steam boiler;
[0026] 4. When a certain amount of distilled seawater is produced, that is, when the liquid level in the distilled water tank reaches a certain height, the first water treatment device can be stopped, which can reduce the purchase of consumables for the first water treatment device and reduce the equipment cost of the seawater purification process;
[0027] 5. The distilled seawater is used to provide water for the electrode steam boiler. According to the water volume and user usage, multiple distilled water tanks can be connected to achieve internal circulation of water source. It has a wide range of applications and maximizes resource utilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1:
[0035] like Figure 1 , Figure 2As shown, the utility model provides a novel seawater purification device, including a purification device system, which is arranged near a wind power station 1, and the purification device system includes an electrode steam boiler 4, which is connected to the wind power station 1, and the wind power station 1 is connected to the electrode steam boiler 4, and the electrode steam boiler 4 is used to generate saturated steam up to 204°C, and its electricity is provided by the wind power station 1; the electrode steam boiler 4 is respectively connected to a second water treatment device 3 and a third water treatment device 5, and the third water treatment device 5 extracts seawater 8 through a water pump 7, and the third water treatment device 5 is connected to a distilled water tank 6, and the distilled water tank 6 is connected to the second water treatment device 3. In this embodiment, the second water treatment device 3 is a deaerator, which is used to remove oxygen from the water in the distilled water tank 6, and the third water treatment device 5 is a multi-stage distillation and filtration device, which uses the steam generated by the electrode steam boiler 4 as a thermal drive to filter the seawater 8 extracted from the water pump 7, and the distilled water tank 6 is used to store the distilled seawater generated by the third water treatment device 5, and finally can be connected to a user 9.
[0036] The water pump 7 is also connected to the first water treatment device 2, and the first water treatment device 2 is connected to the second water treatment device 3. In this embodiment, the first water treatment device 2 includes a softening water system and a reverse osmosis filtration system to provide a pure water source for the first operation of the boiler.
[0037] This device is driven by the electricity generated by the wind power station 1, which provides electricity for the electrode steam boiler 4 and other auxiliary equipment. Since the wind resources at the seaside are abundant and more stable than solar thermal energy, and the temperature of the steam generated is constant, the distillation system works more stably and the quality of the filtered seawater is better. When this device is operated for the first time, a part of the seawater needs to be filtered through the first water treatment device 2.

When a certain amount of distilled seawater is produced, that is, when the liquid level in the distilled water tank 6 reaches a certain height, the water treatment device 2 can be stopped, and the distilled seawater can be used to provide water for the electrode steam boiler to achieve internal circulation of the water source. Since the consumables required by the first water treatment device 2 are relatively expensive, the first water treatment device 2 can be stopped after stable operation, which can reduce the purchase of consumables and reduce the equipment cost of the seawater purification process; the steam produced by the electrode steam boiler 4 passes through the third water treatment device 5, is cooled and condensed into pure water, and is recovered into the distilled water tank together with the distilled seawater.
