Description

Technical Field

[0001] The utility model belongs to the technical field of bromine extraction from seawater, and in particular relates to a neutralization device for wastewater extracted from bromine from seawater. Background Art

[0002] Extracting bromine from seawater will produce some wastewater containing chemicals or bromine residues. These wastewaters need to be treated to ensure that the impact on the environment is minimized and meets the relevant emission standards. The neutralization process in wastewater treatment can adjust the pH value of the wastewater and adjust its pH value to a range that complies with environmental regulations and standards to reduce adverse effects on the environment. There may be a large amount of salt in the wastewater after debromination, which can be used as a raw material for salting. These bromides and other salts can be precipitated.

[0003] Neutralizing agent is added to the wastewater and stirred continuously to ensure that the neutralizing agent is evenly distributed throughout the wastewater to achieve the purpose of neutralization. However, if there are some salt raw materials in the wastewater, the direct neutralization of the wastewater from seawater extraction of bromine will easily lead to the loss of the raw materials, resulting in poor wastewater treatment effect.

[0007] Wherein, the neutral seat is provided with two telescopic positioning holes, and the two combined top columns are respectively slidably connected in the two telescopic positioning holes.

[0008] There is a gap cavity between the bottom end surface of the neutral seat and the top end surface of the bottom support plate, and the outer end of the combined top column is located in the gap cavity.

At this time, the wastewater can be precipitated, and the sediment can be accumulated on the inclined side of the bottom support plate and enter the collection box through the leaching trough.
