Abstract

The invention discloses multi-frequency supersonic wave algae removing equipment comprising a multi-frequency supersonic wave signal generator and a supersonic wave emitting probe. The multi-frequency supersonic wave signal generator comprises: a power source used for supplying power; a frequency conversion signal source used for periodically and alternatively exciting high-frequency electrical signal circuits such that high-frequency exciting electrical signals are generated for exciting the supersonic wave probe to emit supersonic wave signals, wherein at least two different high-frequency electrical signal circuits are contained in the frequency conversion signal source; a power amplifier used for amplifying the powers of the high-frequency exciting electrical signals and outputting the high-frequency exciting electrical signals to a high-frequency output transformer; and the high-frequency output transformer used for formalizing the high-frequency exciting electrical signals and outputting the signals to the supersonic wave emitting probe. The equipment provides a multi-frequency working mode. Within a same time span, supersonic wave signals with different frequencies can be generated alternatively for removing algae, such that vacuoles in algae can be easily and rapidly compressed, collapsed, and destroyed, such that good algae removing effect is achieved.

Description

technical field [0001] The invention relates to an algae removal device, in particular to a multi-frequency ultrasonic algae removal device. Background technique [0002] With the development of social economy, the problem of water pollution has become increasingly prominent, among which eutrophication is a kind of water pollution. [0003] Eutrophication refers to the phenomenon of water quality pollution caused by excessive content of plant nutrients such as nitrogen and phosphorus in lakes, rivers, reservoirs and other water bodies. Due to the enrichment of nitrogen and phosphorus nutrients in the water body, the rapid reproduction of algae and other plankton is caused, the dissolved oxygen content of the water body is reduced, and the pollution phenomenon of the decline or even extinction of algae, plankton, plants, aquatic organisms and fish is caused. Therefore, algae removal has become an urgent problem in environmental governance. [0004] Ultrasonic algae removal ...
