Embodiment 2

[0086] Such as figure 2 As shown, the method for adding carbonic acid by using a small-scale carbonic acid solution dosing system in this embodiment is basically the same as the method for adding carbonic acid by using a small-scale carbonic acid solution dosing system in Example 1; the difference is that the diffuser 6 is set In the pool to be treated without water flow, multiple channels for releasing the carbonic acid solution are opened on the double side walls of the diffuser 6; the channels for releasing the carbonic acid solution are a combination of small holes and narrow gaps.

[0087] 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.

[0088] The channel (small hole 9 and narrow gap 8) for releasing the carbonic acid...

Embodiment 3

[0092] The method for adding carbonic acid by using a small-scale carbonic acid solution dosing system in this embodiment is basically the same as the method for adding carbonic acid by using a small-scale carbonic acid solution dosing system in Example 1; the difference is that the carbonic acid solution pipeline 15 is For large-diameter pipes larger than DN25, the channel for releasing the carbonic acid solution is a narrow slit, with a row of narrow slits 8 in the middle and a row of narrow slits 8 on both sides.

Abstract

The invention discloses a method for adding carbonic acid by adopting a small carbonic acid solution adding system. The method comprises the following steps: 1) establishing a small carbonic acid solution adding system which comprises a reaction tank, a diffuser, a carbon dioxide gas pipeline, a reaction water pipeline and a water pump, wherein a water mist nozzle and a carbon dioxide gas nozzle are arranged at the top in the reaction tank, a control valve is arranged between the reaction tank and the diffuser, the diffuser is arranged in water to be treated, a channel for releasing the carbonic acid solution is formed in the side wall of the diffuser and can generate certain back pressure to spray the supersaturated carbonic acid solution into water to be treated; 2) feeding the carbon dioxide gas into a reaction tank at a certain temperature and under a certain pressure; (3) pressurizing the reaction water by the water pump, and feeding the reaction water into the reaction tank from the tank top in a high-pressure mist form; and 4) arranging a water quality on-line detector in the raw water, and controlling the opening degree of the control valve by connecting a signal receiver with a PLC controller. According to the method, the water quality can be accurately adjusted, meanwhile, bubbles can be greatly reduced, and the utilization rate of carbon dioxide gas is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a method for adding carbonic acid by using a small-scale carbonic acid solution dosing system for applications such as adjusting the pH value of water, remineralization or lime softening. The method of adding carbonic acid by using a small-scale carbonic acid solution dosing system is suitable for occasions where the amount of water treatment is small and it is not necessary to generate a large amount of carbonic acid solution quickly. For example, fish ponds, shrimp ponds, swimming pools, vegetable greenhouses, flower planting, small seawater desalination, etc. Background technique [0002] In surface water, reservoir water, wastewater, and manufacturing process water, there may be too high pH, ​​exceeding pH 8.0 or even above 9. Excessively high and unstable pH of water will seriously affect subsequent chemical treatment and product quality . For example, the pH of the ...
