Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an ozone water treatment device. Background Art

[0002] Humans have been treating water for many years. Regardless of the water treatment method, the purpose is to improve water quality, that is, to meet certain water quality standards. Usually, there are many types of water treatment, such as physical water treatment, chemical water treatment, and biological water treatment, according to different treatment methods. Among them, physical methods include using filter materials with different pore sizes to remove impurities in water by adsorption or barrier methods. The more important adsorption method is adsorption with activated carbon, and the barrier method is to pass water through the filter material so that larger impurities cannot pass through, thereby obtaining cleaner water. At present, in water treatment devices using physical methods, when the water ejector absorbs ozone into the water flow, disperses and mixes it, and then dissolves it in water under a certain pressure, it is necessary to maintain the system pressure and use a booster pump to increase the water pressure, which consumes a lot of energy. At the same time, if the inlet pressure of the water ejector is small during the treatment process, the negative pressure generated at its throat is smaller than the atmospheric pressure, and the outlet pressure of the water ejector will decrease as its inlet pressure decreases, resulting in a decrease in system pressure, thereby reducing the solubility of ozone in water and affecting the low water purification efficiency. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the utility model is to provide an ozone water treatment device that can adjust the ozone intake volume in real time to fully mix ozone and water, thereby improving the ozone solubility and thus improving the water purification efficiency.

When the water in the water storage tank 1 enters the water ejector 2 through the water delivery pipe 101, the ozone in the ozone tank 3 enters the water ejector 2 through the anti-backflow pipe 301, and the ozone and water are mixed and then enter the mixing device 5 through the mixed liquid delivery pipe 201, so that the ozone and water are mixed again, and then enter the nozzle 7 through the oxygen mixing pipe 6 after mixing again, and finally output after mixing; at the same time, the regulating pipes arranged at the input and output ends of the water ejector 2 adjust the pressure at both ends of the water ejector 2 in real time.

When the pressure is low, the regulating pipe is closed, and the water-oxygen mixed liquid cannot pass through and can only pass through the water ejector 2; in addition, by setting the oxygen delivery pipeline 4, the ozone input into the mixing device 5 can be adjusted to further mix the ozone and water, increase the ozone in the mixed liquid, and improve the ozone solubility, thereby improving the water purification efficiency. The utility model can adopt a multi-stage mixing structure to mix ozone and water, and can adjust the ozone suction volume in real time to fully mix ozone and water, thereby improving ozone solubility and thus improving water purification efficiency.

[0021] The above-mentioned oxygen supply pipeline 4 includes a first output pipe 401 arranged at the lower part of the ozone tank 3, and a first regulating valve for adjusting the output flow is arranged on the first output pipe 401.

The second branch pipe 404 is also connected to a second bypass pipe 405, and the second bypass pipe 405 is connected to the input end of the water ejector 2. Through the arrangement of this structure, when ozone enters the mixing device 5 from the first output pipe 401 at the lower part of the ozone tank 3 through the first branch pipe 402, the output flow of the first output pipe 401 is adjusted by the first regulating valve, so that ozone and water are fully mixed to form a mixed liquid, and the excess ozone returns to the first output pipe 401 through the first bypass pipe 403; then, the ozone newly entering the mixing device 5 and the above-mentioned mixed liquid are further mixed in the mixing device 5, and the excess ozone flows into the input end of the water ejector 2 through the second bypass pipe 405, and the solubility of ozone in the water ejector 2 is further adjusted. Furthermore, a second flow regulating valve is installed on the first branch pipe 402, and a third pressure gauge is installed on the second bypass pipe 405.

After the ozone and water are mixed again, they enter the nozzle 7 through the oxygen mixing pipe 6 and are finally mixed and output. At the same time, the regulating pipes arranged at the input and output ends of the water ejector 2 adjust the pressure at both ends of the water ejector 2 in real time. When the pressure in the water ejector 2 is high, the excess water-oxygen mixed liquid directly enters the mixed liquid delivery pipe 201 through the regulating pipe.
