Description

Technical Field

[0001] The utility model relates to the technical field of brackish water desalination and purification equipment in high-cold areas, in particular to a brackish water desalination and purification device used in high-cold areas. Background Art

[0002] Bitter and salty water in high-altitude cold regions contains a large amount of impurities such as salt, sulfate, and magnesium ions. Drinking it directly will have adverse effects on human health, affecting the digestive system, increasing the burden on the kidneys, and affecting bone health. Impurities in the bitter and salty water may also cause other health problems such as skin allergies and cardiovascular diseases. Therefore, the bitter and salty water in high-altitude cold regions must be purified to remove impurities in order to meet the needs of daily drinking and industrial production.

[0003] However, the low temperature environment in high-altitude and cold regions will reduce the effectiveness of membrane separation technology, resulting in decreased desalination efficiency and increased energy consumption, which in turn leads to higher technical costs.

[0004] In the prior art, commonly used insulation materials, such as glass wool and rock wool, have reduced insulation effects in low-temperature environments and cannot meet the requirements for brackish water desalination and purification in high-cold areas. In low-temperature environments, insulation materials are prone to aging and damage, requiring frequent maintenance, which increases maintenance costs and difficulty.

[0005] Traditional insulation methods, such as wrap insulation and interlayer insulation, are prone to problems such as freezing and frost heave in high-altitude cold areas, resulting in reduced insulation effects.

[0006] How to solve the above problems is the research focus of this program. Utility Model Content

[0007] In order to achieve the above-mentioned purpose of the utility model and to solve the above-mentioned technical problems, the utility model provides a water purification device for desalination of brackish water in high-altitude and cold areas.

[0008] The technical solution is as follows: it comprises a reverse osmosis water purification unit arranged on a bottom plate, and a quartz sand filter, an activated carbon filter and a softening filter are arranged behind the reverse osmosis water purification unit;

[0009] The quartz sand filter, activated carbon filter and softening filter all include tanks, and the three tanks are interconnected to increase the water flux;

[0010] The outer wall of the tank is provided with a heating unit.

[0011] The heating unit comprises an arc-shaped plate abutting against the outer wall of the tank body, and an electric heating plate is arranged inside the arc-shaped plate.

[0012] The arc-shaped plates are arranged in two symmetrical pieces, and the two arc-shaped plates match the outer wall of the tank;

[0013] An arc-shaped connecting plate 1 is arranged on the outer wall of one of the arc-shaped plates, and an arc-shaped connecting plate 2 is arranged on the outer wall of the other arc-shaped plate. Both ends of the arc-shaped connecting plate 1 and the arc-shaped connecting plate 2 are provided with connecting ear plates.

[0014] The connecting ear plates of the arc-shaped connecting plate 1 and the arc-shaped connecting plate 2 are both provided with threaded holes, and the connecting ear plates of the arc-shaped connecting plate 1 and the arc-shaped connecting plate 2 on the same side are fixedly connected by threaded rods.

[0015] A connecting block is provided in the middle of the outer wall of the arc-shaped connecting plate 1, and a plurality of transverse connecting grooves are provided on the connecting block, and a plurality of inserts corresponding to the connecting grooves are provided on the outer wall of the arc-shaped connecting plate 2;

[0016] The connecting block and the insert plate are vertically provided with upper and lower corresponding through holes, and a limit rod is slidably matched in the through hole, and a limit plate is arranged on the top of the limit rod.

[0017] The diameter of the limiting plate is greater than the diameter of the through hole.

[0018] The electric heating plate is in contact with the outer wall of the tank.

[0019] A temperature sensor is arranged on the bottom plate.

[0020] The reverse osmosis water purification unit uses the selective permeability of the reverse osmosis membrane to intercept the salt and other impurities in the brackish water to obtain pure fresh water. It effectively removes the salt and other impurities in the brackish water and produces fresh water that meets the standards for drinking and industrial production.

[0021] The quartz sand filter uses the filtering effect of quartz sand to remove impurities such as suspended matter and colloids in the water, further improving the purity of the water and reducing the operating load of subsequent equipment.

[0022] Activated carbon filters use the adsorption effect of activated carbon to remove organic matter, pigments, odors and other impurities in water, improve the taste of water and enhance the quality of water.

[0023] The softening filter uses resin exchange to remove hardness ions such as calcium and magnesium in the water, prevent scale formation, and protect pipes and equipment.

[0024] The heating unit uses an electric heating plate to heat the water in the tank to increase the water temperature, thereby improving the desalination efficiency of the reverse osmosis membrane and preventing the membrane performance from deteriorating in low temperature environments.

[0025] The temperature sensor detects the water temperature and feeds it back to the control system to control the heating unit and ensure that the water temperature reaches the optimal state.

[0026] The reverse osmosis water purification unit includes a pretreatment system, a high-pressure pump, a reverse osmosis membrane, a brine discharge system, a water storage tank, a post-treatment system, etc. This is the existing technology and will not be repeated here.

[0027] The temperature sensor is electrically connected to the electric heating plate.

[0028] The pretreatment system removes large particles and some pollutants in the water, reducing the burden on the reverse osmosis membrane.

[0029] The high pressure pump provides the required operating pressure for the reverse osmosis membrane.

[0030] The brine discharge system discharges the concentrated brine produced by the reverse osmosis membrane.

[0031] The water storage tank stores the produced fresh water.

[0032] The post-treatment system disinfects and adds minerals to the produced fresh water to make it more in line with drinking standards.

[0033] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the solution realizes heat storage and heat preservation by setting a heating unit, adopts an arc-shaped heating unit, and fits tightly with the outer wall of the tank body, thereby improving the heating efficiency and reducing heat loss. The adjustable limit and fixing mechanism is adopted, which is convenient for disassembly and assembly, and can be adjusted according to different ambient temperatures to save energy. The device is highly practical and can effectively solve the problem of shortage of bitter and salty water resources in high-cold areas, and provide reliable water resources guarantee for the lives and production of local residents.

[0034] The heating unit can increase the water temperature, thereby improving the effect of membrane separation technology, increasing desalination efficiency, and reducing energy consumption; the heating unit can reduce the impurity content in the water, reduce membrane pollution, extend the service life of the membrane, and thereby reduce operating costs.
