Clearing device for floating green algae in Lake Taihu

Abstract

The invention provides a clearing device for floating green algae in the Lake Taihu, and relates to the field of environmental protection equipment. The clearing device is composed of movable float bowls, high-pressure air cylinders, an air storage box, air spray pipes, a solar panel, a motor, an axial flow pump, an impeller, meshes, a honeycomb type adsorption sponge and adsorption resin. A first power system is composed of the solar panel, the motor and the axial flow pump. A second power system is composed of the movable float bowls, the high-pressure air cylinders, the air storage box and the air spray pipes. A clearing system is composed of the meshes, the honeycomb type adsorption sponge and the adsorption resin. In sunny days, solar energy is converted into electric energy through the solar panel so that the motor and the axial flow pump can work; and in rainy days, wave energy is concentrated in the air storage box through the movable float bowls and the high-pressure air cylinders, and the device is driven by the air spray pipes to work. The device can clear away the floating green algae on the lake surface and can filter out in-lake green algae on a shallow water layer. Power energy of the device comes from solar energy and lake surface wave energy, and is completely environment-friendly, no floating oil pollution is generated to the lake surface, manual energy supplementation is not needed, and the clearing device is small in size, simple in structure, convenient to maintain, remarkable in alga removal and not high in manufacturing cost.

Description

technical field [0001] The invention relates to a device for cleaning floating objects in rivers and lakes, in particular to a device for cleaning floating green algae, which belongs to the technical field of environmental protection equipment. Background technique [0002] In recent years, the pollution of Taihu Lake has become more and more serious. Green algae outbreaks in Taihu Lake are irregular. Green turbid lake water and floating green algae floating on the lake can often be seen along the leeward coast of Taihu Lake. The state allocated a huge amount of special funds for the treatment of Taihu Lake many years ago. The ecological environment of Taihu Lake has improved to a certain extent, but the pollution of Taihu Lake and green algae still exist, and all aspects of the society need to make great efforts to carry out comprehensive treatment. At present, the main methods and measures for the comprehensive treatment of Taihu Lake are: government administrative interven...

[0002] In recent years, the pollution of Taihu Lake has become more and more serious. Green algae outbreaks in Taihu Lake are irregular. Green turbid lake water and floating green algae floating on the lake can often be seen along the leeward coast of Taihu Lake. The state allocated a huge amount of special funds for the treatment of Taihu Lake many years ago. The ecological environment of Taihu Lake has improved to a certain extent, but the pollution of Taihu Lake and green algae still exist, and all aspects of the society need to make great efforts to carry out comprehensive treatment. At present, the main methods and measures for the comprehensive treatment of Taihu Lake are: government administrative intervention and demolition or shutting down the surrounding areas of Taihu Lake Paper mills, tanneries, wood factories, cement factories and chemical plants, etc., which pollute Taihu Lake, use floating ball and screen filtration at the physical level, resin adsorption at the chemical level, and fish farming at the biological level. Algae method, grass planting water purification method is adopted at the agricultural and forestry level. The above methods have their own characteristics and can reduce the concentration of green algae in Taihu Lake to a certain extent. However, some of these methods have high costs, some have a longer cycle, and some have insufficient effects.
