Problems solved by technology

[0006] In addition to the traditional use of aeration head aeration, there is another way to use aeration is to mix the water to be treated with oxygen through a Venturi nozzle or a static mixer and then add the mixture to the water to be treated. It can be added to shallow pools and high-concentration oxygen-enriched solution pipelines, but it also faces the problems of small oxygen bubbles escaping and low efficiency of dissolved oxygen

Embodiment 1

[0054] In this embodiment, a method for adding a high-concentration oxygen-enriched solution using an oxygen-enriched solution dosing system includes the following steps:

[0055] (1) Establish a high-concentration oxygen-enriched solution dosing system; figure 1 As shown, the high-concentration oxygen-enriched solution dosing system includes a liquid oxygen storage tank 1, an electronic vaporizer 2, a reaction tank 5, and a diffuser 6 connected in sequence, and also includes a tank top of the reaction tank 5 through a fused water pipeline 11. The water pump 4 that the water inlet connects; On the oxygen pipeline 12 that electronic vaporizer 3 outlets are connected with the gas inlet of reaction tank 5 tank tops, be provided with pressure-regulating valve group 10; Fusion water pipeline 11 and oxygen pipeline 12 respectively have a little section stretching into In the reaction tank 5; the tank top in the reaction tank 5 is provided with a water mist nozzle (connected with the...

Embodiment 2

[0074] The method of using the oxygen-enriched solution dosing system to add high-concentration oxygen-enriched solution in this embodiment is basically the same as the method of using the oxygen-enriched solution dosing system to add high-concentration oxygen-enriched solution in Example 1; the difference is that :

[0075] Diffuser 6 is arranged in the pool to be treated without water flow, and a plurality of channels for releasing oxygen-enriched solution are opened on the double-sided side walls of diffuser 6; the channels for releasing oxygen-enriched solution are small holes and narrow gaps. A combination of the two.

[0076] Such as figure 2 Shown, diffuser 6 is arranged in the pool that does not have water flow to be treated, has many circles of small holes and narrow slits (a row of small holes 9, a row of narrow slits 8) on the whole cylindrical side wall of diffuser 6 staggered arrangement) to achieve 360° delivery.

[0077] The channel (small hole 9 and narrow ...

Embodiment 3

[0080] The method of using the oxygen-enriched solution dosing system to add high-concentration oxygen-enriched solution in this embodiment is basically the same as the method of using the oxygen-enriched solution dosing system to add high-concentration oxygen-enriched solution in Example 1; the difference is that : The high-concentration oxygen-enriched solution pipeline 15 is a large-diameter pipeline greater than DN25, and the channel for releasing the high-concentration oxygen-enriched solution is a narrow gap, with a row of narrow gaps 8 in the middle and a row of narrow gaps 8 on both sides.

Abstract

The invention discloses a method for adding a high-concentration oxygen-enriched solution by adopting an oxygen-enriched solution adding system. The method comprises the following steps: 1) establishing an oxygen-enriched solution adding system which comprises a reaction tank, a diffuser, a pressure regulating valve group and a water pump, wherein a water mist nozzle and an oxygen nozzle are arranged at the top in the reaction tank, a control valve is arranged between the reaction tank and the diffuser, the cylindrical side wall of the diffuser is provided with a channel for releasing an oxygen-enriched solution, namely a small hole or a narrow gap or a combination of the small hole and the narrow gap, and the channel can generate certain back pressure to ensure that the pressure difference between the outlet pressure of the diffuser and the water pressure to be treated is more than 2 bar; 2) regulating the pressure of oxygen to a certain pressure and feeding into a reaction tank; 3) pressurizing the dissolved water to a certain pressure through a water pump, and feeding the dissolved water into a reaction tank from the top of the tank in a high-pressure mist form; 4) arranging a water quality on-line detector at the water outlet, and controlling the opening degree of the control valve through the connection of a signal receiver and the PLC. According to the method, the water quality can be accurately adjusted, meanwhile, the generation of bubbles can be greatly reduced, and the utilization rate of oxygen is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to a method for adding a high-concentration oxygen-enriched solution by using an oxygen-enriched solution dosing system. The method of adding high-concentration oxygen-enriched solution by using an oxygen-enriched solution dosing system is suitable for occasions where the water treatment volume is small and high-concentration oxygen-enriched solution does not need to be generated rapidly and in large quantities. For example, fish ponds, shrimp ponds, small ponds, etc. Background technique [0002] Dissolved oxygen is an important chemical parameter of water quality. Under natural conditions, the oxygen content in the air does not change much. The oxygen dissolution rate in water bodies at different altitudes is slightly different, mainly due to algae activities, which generate dissolved oxygen in water bodies. The amount of dissolved oxygen in water is an index to measure the ...
