Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a brackish lake water purification device. Background Art

[0002] Saltwater lakes refer to lakes with high salt content. They are usually formed when the lake water is not discharged or discharged poorly, and evaporation causes the salt in the lake water to accumulate. They are mostly formed in dry inland areas. Saltwater lakes in China include Qinghai Lake, Selin Co, and Nam Co. These places are often water-scarce areas, and the lake water cannot be directly drunk, so the lake water needs to be desalinated.

[0003] The desalination of brackish water is essentially the desalination of salt water, which makes the salt water desalinated or treated to meet the drinking water standards. At present, the treatment methods of brackish water mainly include distillation, electrodialysis and reverse osmosis. Distillation is an ancient desalination method. It heats brackish water to make it boil and evaporate, and then condenses it into fresh water. This method has simple structure and easy operation, but it has disadvantages such as high power consumption, high operating costs, and easy corrosion and scaling. Electrodialysis uses ion exchange membranes to separate anions and cations in water under the action of an electric field, thereby reducing the concentration of salt. This method has the advantages of simple process, high salt removal rate, and low water production cost, but it requires pretreatment of raw water and has strict requirements on water quality. Reverse osmosis is to apply a higher pressure than natural osmosis on one side of the concentrated solution, reverse the direction of natural osmosis, and press the ions in the solution to the other side of the semipermeable membrane to achieve the purpose of desalination. The cost of reverse osmosis is relatively high. The Chinese patent "An integrated water purification equipment for desalination of brackish water" (application number: 202410632823.X) uses reverse osmosis technology, which has a complex structure and high operating costs.

[0048] The working principle and specific process of the present invention:

[0049] 1. Release the brackish lake water purification device into the lake water, and moor the inflatable rubber ring 1 to the shore by means of a cable to prevent the brackish lake water purification device from drifting away. Turn on the switches of the electric heater 2023 and the atomizer 2035 to start working.

[0050] 2. Lake water enters the water inlet chamber 201 through the water inlet 2011 of the water inlet chamber, and the filter mesh filters out the coarse objects in the water. Then the lake water enters the heating chamber 202 through the water outlet 2012 of the water inlet chamber and the water inlet 2021 of the heating chamber.

[0051] 3. The electric heater 2023 heats the lake water, and the water vapor mixture generated after heating enters the atomization chamber 203 through the heating chamber water outlet 2022 and the atomization chamber water inlet 2031 under the action of pressure difference.

[0052] 4. The atomizer 2035 generates ultrasonic waves by high-frequency resonance caused by electronic high-frequency oscillation. When ultrasonic waves propagate in water, cavitation occurs. The water around the cavities is crushed into 1-3 μm particles by the cavitation explosion between water and air, so that water mist is generated on the water surface. The mist vapor enters the spiral condenser 2042 through the mist vapor outlet 2034; the bitter and salty concentrated lake water generated after heating and atomization flows out of the atomization chamber 203 through the atomization chamber outlet 2032 under the action of water pressure.

[0053] 5. The mist vapor exchanges heat with the external cold air in the spiral condenser tube 2042. The mist vapor is cooled to form condensed water and flows into the condensed water receiving barrel 2043. The condensed water receiving barrel 2043 is regularly recovered and replaced.

[0054] 6. After the brackish lake water purification device has been running for a certain period of time, the filter screen will be clogged, and the electric heater 2023 and the atomizer 2035 will also be scaled and need to be backwashed. Close the switches on the atomization chamber outlet 2032 and the mist steam outlet 2034, start the backwash pump 4, and high-pressure water enters the atomization chamber 203 through the backwash water inlet to wash the atomizer 2035, the electric heater 2023 and the filter screen in turn. When there is large dirt, remove the filter screen, and the backwash water is discharged from the water inlet 2011 of the water inlet chamber.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can still adjust the technical solutions described in the above embodiments or replace some of the technical features by equivalents.
