Problems solved by technology

However, it still has the following disadvantages: (1) waste of energy and pollute the environment
Consume more electric energy or fossil energy, thereby polluting water quality and air; (2) High consumption cost
High power consumption and high cost of laying cables; (3) Affects aquatic ecology
During operation, the water is disturbed violently, generating a lot of noise, which can easily affect the growth of aquatic animals; (4) increase the turbidity of the water body
It is easy to pump mud and other substances at the bottom of the water body, which will cause turbidity of the water body; (5) The scope of application is limited
Generally only suitable for aeration of lakes and ponds, it is difficult to apply to marine fisheries
[0003] In order to solve the problems of high power consumption, limited application range and fixed oxygenation range of the aerator, some scholars have proposed to use other energy sources to power the oxygenation device, such as "a valve-type aeration and oxygenation device based on wave energy " and "a self-propelled intelligent aerated and oxygenated ship based on the principle of OWC", etc., but the two still have the following deficiencies: the former has a fixed installation position, limited flexibility, inconvenient movement, and limited oxygenation range and depth; the latter The stability is poor, the structure is relatively complex, and due to the low air outlet pressure and the limited depth of oxygenation, it is difficult to meet the current development needs of deep-sea aquaculture and marine ranching

Abstract

The invention discloses a novel oscillating water column type oxygenation ship based on a turbocharging technology and an oxygenation method thereof.The novel oscillating water column type oxygenation ship comprises a main ship body, a steel frame platform is installed on the main ship body, a U-shaped oscillating water tank is installed on the steel frame platform, and water is injected into the U-shaped oscillating water tank to divide the two sides of the U-shaped oscillating water tank into two air chambers which are not communicated; a one-way air inlet valve and a one-way air outlet valve which are communicated with the air chamber on the side are arranged on the two sides of the U-shaped oscillation water tank respectively, the two sides of the U-shaped oscillation water tank are each provided with a compressor, air inlets of the two compressors are communicated with the one-way air outlet valve on one side of the U-shaped oscillation water tank through pipelines respectively, and air outlets of the two compressors are communicated with pipelines extending to the bottom of the ship respectively. Turbines in the two compressors are respectively connected with an impact turbine at the bottom of the ship through a vertical rotating shaft, the upper portion and the lower portion of each shell are open, and fixed blades are installed on the upper portions and the lower portions of the impact turbines. The oxygenation ship disclosed by the invention is simple in structure, economical in material, low in cost and suitable for being put into production and use; the compressor and the impact turbine are arranged to improve the air outlet oxygenation depth.

Description

technical field [0001] The invention belongs to the field of water body oxygenation devices, and in particular relates to a new type of oscillating water column type oxygenation ship based on turbocharging technology in the field and an oxygenation method thereof. Background technique [0002] At present, there are three main methods for improving the oxygen content of water body: mechanical, chemical and biological. Among them, mechanical oxygenation is the most commonly used oxygenation method. Its principle is mainly to use electrical energy to make mechanical parts agitate the water body, speed up convective exchange and interface renewal, and achieve the purpose of increasing the oxygen content of the water body. The mechanical aerators commonly used in production mainly include impeller type aerators, waterwheel type aerators, etc. However, it still has the following shortcomings: (1) Waste energy and pollute the environment. Consume more electric energy or fossil en...
