Embodiment 1

[0061] like figure 1 As shown, the present embodiment is a carbonic acid solution dosing system applied to adjust the pH value of water, which includes a liquid carbon dioxide storage tank 1, an electronic vaporizer 2, a gas heater 3, a mixer 5 and a diffuser 6 connected in sequence, Also comprise the water pump 4 that is connected with mixer 5 inlets; Between mixer 5 and diffuser 6, be provided with annular coil pipe 14 and long-distance pipeline 17 (straight pipe); In the water pipeline, located upstream of the water flow, inserted into the water pipeline perpendicular to the direction of the water flow; half of the side wall of the diffuser 6 has a number of channels for releasing the carbonic acid solution, and the channels for releasing the carbonic acid solution can generate a back pressure above 3bar And the supersaturated carbonic acid solution is sprayed into the water to be treated with an outlet pressure greater than 3bar (reverse injection into the water upstream o...

Embodiment 2

[0080] 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.

[0081] Such as figure 2Shown, 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.

[0082] The channel (small hole 9 and narrow gap 8) for releasing the carbonic acid ...

Embodiment 3

[0086] The carbonic acid solution dosing system of the present embodiment is basically the same as the carbonic acid solution dosing system in embodiment 1; The difference is: a liquid storage tank 15 and a long-distance pipeline are arranged between the mixer 5 and the diffuser 6 17 (straight pipe). The long-distance pipeline 17 is a large-diameter pipeline greater than DN25, and the channel for releasing the carbonic acid solution is a narrow slit 8 with a row of narrow slits 8 in the middle and a row of narrow slits 8 in both sides.

[0087] The pressure gas-water mixture enters the liquid storage tank 15, and the pressure generated by the gas-water mixture continuously acts on the tank wall and the reaction force of the tank wall dissolves the carbon dioxide bubbles in the water, finally forming a supersaturated carbonic acid solution. The supersaturated carbonic acid solution is sent to the diffuser 6 through the long-distance pipeline 17 (straight pipe). At the same time...

Abstract

The invention discloses a carbonic acid solution adding system. The system comprises a mixer and a diffuser, and further comprises a carbon dioxide gas pipeline and a reaction water pipeline; a water pump is arranged on the reaction water pipeline; the water pump outlet is connected with a mixer inlet; the carbon dioxide gas pipeline is connected with the mixer inlet; an annular coil pipe or a liquid storage tank and a long-distance pipeline are arranged between the mixer and the diffuser; the diffuser is arranged in water to be treated; the side wall of the diffuser is provided with a channel for releasing a carbonic acid solution, and the channel for releasing the carbonic acid solution is a small hole or a narrow gap or a combination of the small hole and the narrow gap; and the channel for releasing the carbonic acid solution can generate certain back pressure and enable the supersaturated carbonic acid solution to be sprayed into water to be treated at certain outlet pressure, and it is guaranteed that the pressure difference between the outlet pressure of the diffuser and the water pressure to be treated is 2 bar or above. The carbonic acid solution adding system can accurately adjust the water quality, greatly reduce the generation of bubbles and greatly improve the utilization rate of carbon dioxide gas.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a carbonic acid solution dosing system for adjusting the pH value of water, remineralization or lime softening and the like. 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 effluent at the wastewater terminal should be controlled at 6-9; during the coagulation and disinfection process of the tap water plant, due to the excessively high and unstable pH, excessive chemical agents are added and excessive chemical by-products are produced. As a result, the relevant national standards cannot be reached; in the textile printing and dyeing industry, the pH of the printing and dyeing process water is unstable, which af...
