Water purifier based on synergistic effect of ultrasonic cavitation and photocatalysis

Abstract

The invention discloses a water purifier based on the synergistic effect of ultrasonic cavitation and photocatalysis. An ultraviolet lamp tube and titanium dioxide are arranged in a heating water storage tank to perform photocatalysis sterilization; at the same time, an ultrasonic transducer is arranged at the bottom end of the heating water storage tank, and an ultrasonic wave generated by the ultrasonic transducer is used for sterilization. The ultrasonic cavitation synergistic photocatalysis technology is adopted in the water purifier based on the synergistic effect of ultrasonic cavitationand photocatalysis, the use of a filtering membrane is avoided, the stability of long-term work is ensured, maintenance problems are reduced, and the quality and health of drinking water are ensured.

Description

technical field [0001] The invention relates to the field of water quality sampling devices, in particular to an automatic sampling device for unmanned ships. Background technique [0002] The water purification principles currently used by water purifiers on the market are microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. The water purifiers used are all based on the above four principles or superimposed or optimized production designs. However, these water dispensers still have certain defects. Water purifiers based on ultrafiltration and microfiltration cannot be used independently for drinking water installations; water purified by reverse osmosis filtration is insufficient. Mineral elements are not suitable for long-term drinking; water purifiers based on nanofiltration membrane filtration are easy to clog during actual use, and their service life is much shorter than the theoretical value, and there will also be problems with metal ion filtration, ...

Problems solved by technology

However, these water dispensers still have certain defects. Water purifiers based on ultrafiltration and microfiltration cannot be used independently for drinking water installations; water purified by reverse osmosis filtration is insufficient. Mineral elements are not suitable for long-term drinking; water purifiers based on nanofiltration membrane filtration are easy to clog during actual use, and their service life is much shorter than the theoretical value, and there will also be problems with metal ion filtration, reducing minerals Element content (relative to reverse osmosis membrane light)

In addition, all membrane purification technologies have the following disadvantages: the deposition of dirt on the membrane, therefore, it is still easy to breed bacteria and reduce the quality of purified water after long-term use
