Embodiment Construction

[0039] As shown in Figure 1: In the basic implementation of the present invention, the floating filter system includes two float chains 1, a filter screen 2 that is sealed on the upper edge of a long strip and hangs below the float chains, and a filter net 2 that is located between the two float chains. A collection tank or collection device 3 that is in the middle of the filter screen and is sealingly connected with them at the front end, and a series of counterweight bar chains 4 hanging from the lower edge of the filter screen 2 are arranged at the joints of each float chain 1 and connected with the counterweight bar chain 4 The rope loop 5 at the place, a towing buoy 7 with a tether loop hanging under the water, and the tow rope 6 connecting the aforementioned rope loop 5 and the tether loop below the buoy 7 form a funnel on the plane. A beneficial option is that the float chain 1 is made of a long cylindrical air bag made of polymer material, which can be stretched into a ...

Abstract

The invention relates to a floating filtration system for directly filtering blue algae in water bodies; it is composed of two float chains, a counterweight rod chain, a long filter net, a collection tank, and a buoy with rope rings hanging under the water; The back of the filter screen is sewn or fixed with two mesh cloths along the upper and lower sides, and soft pipes are formed on the upper and lower edges of the mesh cloth, which can respectively penetrate the float chain and the counterweight rod chain; Rope rings are installed at the connection with the counterweight bar chain and the front of the end; it also includes the rope rings arranged at the connection of each buoy chain and the connection of the counterweight bar chain, and the dragging ring connecting the rope ring and the rope ring under the buoy. rope, so that when the buoy is dragged forward, the filter screen is inclined upward to the center, and the filter system forms a funnel with the collection tank as the bottom on the plane. The invention spreads in a funnel shape when being towed in the water body, acts as a tangential flow filter, and can effectively directly concentrate blue-green algae in a vast water body and finally remove the blue-green algae.

Description

technical field [0001] The invention relates to a floating filtration system, in particular to a tangential flow filtration system for salvaging algae in vast water areas. [0002] Background technique: [0003] Algae are crucial in forming and maintaining the existing composition of the atmosphere. It is also crucial in providing biological food. However, it is also harmful when it erupts and can poison bodies of water. The root cause of algal blooms is an excess of nutrients in the water. Living algae are actually cleaners of nutrients in the water. But when it dies and decomposes, it returns nutrients to the water body. In most cases, once a cyanobacterial bloom begins, it lasts until temperatures cool enough. Removing cyanobacteria directly from water bodies may be the most direct and rapid means of solving the problem of harmful cyanobacteria blooms. [0004] The cyanobacteria salvage technology currently being used in Taihu Lake and Dianchi Lake in China is to suc...
