Abstract

The invention discloses a self-powered water surface full-coverage ultrasonic algae removal device and method. The ultrasonic algae removal device comprises a power generation module, a control module, a bearing device, an algae removal module and a water quality monitoring module, wherein the bearing device comprises an engineering plastic plate, a buoyancy tank and N vertical rods; the power generation module comprises M power generation units; the power generation unit comprises a Stirling engine and an electromagnetic generator; the algae removal module comprises N-1 ultrasonic probes; theN-1 ultrasonic probes and the water quality monitoring modules are arranged on the N connecting rods in a one-to-one correspondence manner; and the control module comprises an electric control cabinet, a storage battery and a controller. During work, the temperature difference above and below the water surface is used for compressing and expanding power generation, and the controller controls allwork according to data of the water quality monitoring module. The device generates power based on temperature difference generated by solar radiation heat energy and water body cooling, and has theadvantages of cleanness, high efficiency, high conversion efficiency, low cost, automatic operation and the like.

Description

technical field [0001] The invention relates to the technical field of ecological algae removal, in particular to a self-powered water surface full-cover ultrasonic algae removal device and method. Background technique [0002] With the rapid development of industry, the phenomenon of cyanobacteria bloom has become a common water quality problem faced by lakes and rivers at home and abroad. Aquatic organisms die, which in turn causes a series of ecological problems. There is an urgent need for an efficient, clean and sustainable algae removal solution. Ultrasonic technology to inhibit algae growth and purify water quality has been verified by domestic and foreign research institutions and related units through experiments. The advantages of automatic operation means, no need to introduce chemicals, mild reaction process, fast speed, and no secondary pollution make it have a broad background in the field of water quality protection. In the developed countries led by the Ne...

AI Technical Summary

Problems solved by technology

The MPC-Buoy algae removal device from LG Sonic in the Netherlands can cover a solar-powered ultrasonic algae removal device with a diameter of 500 meters. It includes three ultrasonic probes to achieve sound field radiation in waters. Each transducer must bear 120° ultrasonic For radiation tasks, there must be a certain dead angle for such traditional ultrasonic probes, which cannot radiate sound waves in all directions for algae removal operations

Coupled with the nonlinearity and attenuation characteristics of ultrasonic waves propagating in water, the theoretical ultrasonic radiation angle in waters attenuates severely with the expansion of the range of water bodies
