Abstract

The invention discloses an omnibearing ultrasonic algae removal device and method powered by a Stirling engine. The omnibearing ultrasonic algae removal device comprises the Stirling engine, an electromagnetic generator, an energy storage module, a driving control module, a bearing device, an ultrasonic probe module and an acquisition sensing module, wherein the bearing device is composed of a floating box and N connecting rods, and a limiting through hole is formed in the floating box; the Stirling engine is fixed in the limiting through hole of the buoyancy tank, a hot end air cylinder of the Stirling engine is located above the water surface, a plurality of solar heat collection flat plates are arranged on the outer surface, and a cold end air cylinder is immersed in water; the ultrasonic probe unit comprises a double-headed bolt, two pre-tightening nuts, eight piezoelectric ceramic pieces, two balancing weights and two flange plates. During working, an omnibearing ultrasonic algaeremoval function is performed on the basis of a phased array principle. The device generates power based on temperature difference generated by solar radiation heat energy and water body cooling, andhas the advantages of environmental protection, high working efficiency, no pollution, wide radiation area, good effect and the like.

Description

technical field [0001] The invention relates to the technical field of ecological algae removal, in particular to an all-round ultrasonic algae removal device and method powered by a Stirling engine. 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 ...
