Description

Technical Field

[0001] The present invention discloses a multi-stage disturbance agent diversion and diffusion structure and an aeration and oxygenation dosing ship, which relate to a diffusion structure installed on an aeration and oxygenation dosing ship, and belong to the field of environmental protection technology, and particularly to a diffusion structure that uses multiple oblique flow plates to disturb the water flow gathered between the bow and the bow wing, reduce turbulence and eddy currents, promote the diffusion of chemicals to different depths and areas of the river channel, and can improve the purification efficiency and purification effect of the river channel. Background Art

[0002] With the rapid development of industry and the continuous development and utilization of rivers, a large amount of industrial wastewater, agricultural residues, domestic sewage and solid garbage are discharged into rivers, and the heavy metals, chemical substances and other harmful pollutants contained in them cause the water quality to deteriorate; pesticides, fertilizers and aquaculture residues further lead to eutrophication of water bodies and cause excessive reproduction of duckweed; at the same time, solid garbage soaked in water for a long time will gradually decompose to produce toxic and harmful chemicals and gases, aggravating water quality problems, leading to the death of a large number of aquatic organisms, and seriously affecting the ecological balance of rivers. Therefore, it is necessary to regularly put chemical agents into rivers to absorb heavy metal ions in the water, promote the flocculation reaction of suspended matter and chemical agents in the water to form sediments that sink to the bottom of the river, oxidize organic matter in the water to convert into inorganic matter, and achieve the reduction of water pollutant concentration and improvement of water quality. At present, the work of drug administration in rivers is mainly done manually, but the efficiency of manual drug administration is low, the labor intensity is high, and there is also the risk of falling into the water during water operations. Existing unmanned river drug-dosing ships sail to different locations in the river and then dock to do the dosing. They do not do the dosing synchronously with the sailing of the ship, and the dosing is uneven, or an additional power device is required to carry out uniform dosing. There is no oxygenation device, and the chemical agents cannot be effectively diffused to different depths and areas of the river water relying solely on the fluidity of the water. The purification efficiency of the river water is low and the purification effect is poor.

[0003] Announcement No. CN115195951A discloses an unmanned boat and method for early warning of blue algae blooms and autonomous dosing to inhibit algae. The autonomous dosing system in the unmanned boat is coupled with a monitoring and early warning system. The monitoring and early warning system calculates the dosage of different dosing areas through a fixed algorithm, and the autonomous dosing system will automatically set the number of cycles pushed by the screw at the bottom of the dosing box to quantitatively release the algae inhibitor. The unmanned boat uses the screw at the bottom of the dosing box to push the agent to achieve delivery. The power effect of the screw is poor, the speed of drug delivery is slow, and it can only be delivered to a certain position in the dosing area. The unmanned boat is not equipped with an oxygenation device. The agent cannot be effectively diffused to different depths and areas of the river water by relying solely on the fluidity of the water. The purification efficiency of the river water is low and the purification effect is poor.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "An Aeration and Oxygenation Dosing Ship". The hull includes three parts: a bow, a stern and a bow wing. One end of the bow is placed in the middle of one end of the stern, and one end of the bow wing is placed on both sides of one end of the stern. The chemical agent in the above-mentioned aeration and oxygenation dosing ship flows out from the drug outlet and is directly put into the river channel at the connection between the bow and the bow wing. The connection between the bow and the bow wing is impacted by the water flow, which will produce turbulence and eddies, affecting the diffusion of the chemical agent in the river channel, resulting in low purification efficiency and poor purification effect.
