Problems solved by technology

[0003] The purpose of the present invention is to provide a diversion and gathering device for suspended blue-green algae in low-velocity water bodies, to solve the fences for gathering blue-green algae arranged on the water surface proposed in the prior art, which hinder traffic, affect landscape, block water flow, Seriously affect the negative effects such as ecology, and the fence on the water cannot block the cyanobacteria suspended in the water, which limits the applicability of the fence. Moreover, the fence on the water is easily damaged by foreign objects such as ships, and the construction and maintenance costs are relatively high. high, poor reliability

Embodiment 1

[0037] Example 1: Such as Figure 1 ~ 6 As shown, the present invention provides a technical solution, a fluid flow assembly device for a low flow vendor suspended blue algae, including the air curtain device 1, the fixing device 2, and the machine room 3, the air curtain device 1 is arranged in the river, with The air curtain is generated in the river 13, thereby forming an intangible fence on the water surface, and a fixing device 2 is provided on the air curtain device 1 for fixing the air curtain device 1, and there is a room 3 on the ripple 13;

[0038]The air curtain device 1 is a plurality of groups, including the first conduit 4 and the second conduit 5, the first conduit 4 and the second conduit 5 are arranged in the direction of the water flow direction, and arranged in order to place the first conduit in the direction of the water flow. 4, the second conduit 5 is replaced, and then the first conduit 4 is disposed, and then the second conduit 5 is disposed. The first inta...

Embodiment 2

[0044] Example 2: Such as figure 2 As shown, the length of the first conduit 4 is smaller than the length of the second conduit 5, and the first conduit 4 and the second conduit 5 are arranged in linear type, the first conduit 4 and the second conduit 5 and the water flow direction are arranged in an alpha angular arrangement. figure 2 The direction of the arrow is in the direction of water flow, the α angle range is 0 ° Figure 8-10 The effect of aggregated cyanobacteria can be achieved, and the first conduit 4 forms a gas stream for driving suspended cyanobacteria to the water surface, and the second conduit 5 is formed to form an angle of the river on the side of the river, for aggregation from the first conduit 4 to the water surface. Suspended cyanobacteria and floating cyanobica in the direction of water flow, in linear-type first pipe 4 with linear second conduit 5, the first conduit 4 can also be other shapes, such as V-shaped, bending, etc .;

[0045] The remaining portion...

Embodiment 3

[0046] Example 3: Such as Figure 7 As shown in the direction of the water flow direction, a first conduit 4 is adjacent to the rip towed 13, and then the second conduit 5 is arranged in the water, and finally arranges a first conduit 4 near the ripping 13 on the other side, then repeating the arrangement of these pipes. In the manner, the arrangement of the first conduit 4 is simultaneously suitable for the V-shaped pipe and linear pipe, and the cross-arrangement method of the first conduit 4 makes the airflow band cover the coverage area, which allows more blue algae to be taken to the water surface. It is conducive to raising the efficiency of driving suspended cyanoba to water;

[0047] The remaining portion is the same as in Example 1.

[0048] Working principle: First, the first conduit 4 and the second conduit 5 are arranged in the water body, and the first conduit 4 is connected to the first air pipe 14 by the first intake port 6, the first air pipe 14 and the air mixing pu...

Abstract

The invention discloses a diversion and gathering device for suspending cyanobacteria in low-flow water bodies, which includes an air curtain device, a fixing device and a machine room. The air curtain device is arranged in a river channel, and the air curtain device is several groups of pipelines. The dry set of pipelines includes a first pipeline and a second pipeline, the first pipeline and the second pipeline are arranged in sequence along the water flow direction, and a machine room is provided on one side of the river channel, and an air-water mixing pump and an air pump are installed in the machine room , the present invention is scientific and reasonable, safe and convenient to use, and can be used to gather suspended cyanobacteria and similar floating objects in low-velocity water bodies. The gathered cyanobacteria are beneficial to collection and treatment, so that the water environment is protected.

Description

Technical field [0001] The present invention relates to the field of water environmental engineering technology, in particular to a flow of flow versus a fluid aggregation apparatus for suspended blue algae. Background technique [0002] Algae is one of the largest biological groups on the earth. It is not strict to environmental requirements. It has strong adaptability. Almost everywhere, in recent years, various water bodies have a large growth of algae, resulting in deterioration of water quality, and degradation. The phenomenon, when severe, there is a serious crisis of water, water, and eutrophication, the severity of the blue algae disaster, the crisis, its disaster characteristics is the edge effect, and the disaster mechanism is caused by the glutinous climate, the gathering of the migration, Blood algae drift paths and remove cyanobacteria can effectively prevent the occurrence of cyanobacteria disasters in the local waters, in some water bodies in the rich and numerous ...
