Large simulated type water-surface blue-green algae removing device

Abstract

The invention relates to a large water-surface blue-green algae removing device researched by the principle of simulating chub to filter-feed plankton. The large water-surface blue-green algae removing device adopts a 21m*6m power platform as a carrier and a 50KW diesel generator unit as power; a separating shovel with the width of 10m is arranged at the front end so as to separate surface water rich in blue-green algae when in process, ten branch pump-pipe systems are used for absorbing algae water from the separating shovel, the algae water is conveyed to the algae water to a 600m<2> gill type filter for primary filtration, and then concentrated by a shaking sieve, and a 3m<3> buffer pool stores the algae slurry temporarily; a rear 11KW electric slurry hanging machine provides non-operation drive, a rear 5.5KW frequency-modulation electric slurry hanging machine provides operation drive, and a front 2.2KW spraying propeller provides auxiliary steering power. The width of the operation is 10m, the maximum operation speed is 5km / h, and the capability for absorbing and filtering algae is 1000m<3> / h. The technology can be used for removing the blue-green algae on the lake in a scale manner and has the advantages of high efficiency and low energy consumption.

Description

Technical field: [0001] Large water surface environmental protection (cyanobacteria disaster control) technology. The invention relates to a large-scale water surface cyanobacteria removal device developed by imitating the principle of silver carp filtering plankton in water, which is suitable for large-scale removal of lake surface cyanobacteria and has the advantages of high efficiency and low energy consumption. Background technique: [0002] After the emergence of cyanobacteria pollution problems in lakes in our country, various cyanobacteria collection equipment came into being. Generally, traditional algae water primary separation technologies such as belt sieve filtration, inclined plane filtration, vibrating inclined sieve filtration, flocculation air flotation separation, and electromagnetic separation are widely used. There are problems of low efficiency and high energy consumption. A single machine draws and processes tens of cubic meters of algae water per hour, ...

Problems solved by technology

[0002] After the emergence of cyanobacteria pollution problems in lakes in my country, various cyanobacteria collection equipment came into being. Traditional algal water primary separation technologies such as belt sieve filtration, inclined plane filtration, vibrating inclined sieve filtration, flocculation air flotation separation, and electromagnetic separation are generally used. There are problems of low efficiency and high energy consumption. A single machine draws and processes tens of cubic meters of algae water per hour, and the operating power is tens of kilowatts, which is far from meeting the cyanobacteria disaster control needs of large lakes such as Taihu Lake, Chaohu Lake, and Dianchi Lake. Tons of cyanobacteria are mainly removed by manual salvage, and there is an urgent need for large-scale water surface cyanobacteria removal equipment similar to the "Combine Combine Harvester"
