Description

Technical Field

[0001] The utility model relates to the technical field of mixing towers, and particularly relates to an efficient brine oxidation mixing tower. Background Technique

[0002] Bromine, as an important chemical raw material, plays an important role in the national economy and is widely used in fine chemical industries such as medicine, pesticides, dyes, water purification, flame retardants, pharmaceuticals, refrigeration, and electronic chemicals. With the development of technology, the demand for bromine continues to increase.

[0003] There are various methods for producing bromine. Currently, 90% of bromine production uses the air blowing acid solution absorption method. The key point of this process is the acidification oxidation mixing process of the raw material liquid. Whether the mixing is sufficient determines the level of its production cost.

[0004] After retrieval, the patent number is CN202398352U, which discloses an oxidation tower, including a tower body with a feed inlet at the lower part and a discharge outlet at the top. Its structural feature is that a spiral plate is arranged between the feed inlet and the discharge outlet in the tower body. The oxidation tower is installed on the pipeline after the feed pump and before the bromine analysis tower. When the acidified brine is sent to the bromine analysis tower by the feed pump, chlorine gas is introduced. The chlorine gas and the brine are mixed and reacted in the pipeline, and then enter the oxidation tower. Since there is a spiral plate in the oxidation tower, the conveying stroke is extended, thereby prolonging the contact time between the chlorine gas and the brine, improving the bromine conversion rate while reducing the consumption of chlorine gas and the production cost. However, this technical solution only prolongs the contact time between the chlorine gas and the brine by increasing the conveying stroke, and the mixing is not sufficient, and the production efficiency is not ideal. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an efficient brine oxidation mixing tower to overcome the defects of insufficient mixing and unsatisfactory production efficiency in the existing ones; and achieve the purpose of sufficient mixing and good production efficiency.

[0013] Furthermore, the included angle of the bending part is 90°.

[0014] Furthermore, a pH detection port is provided on the brine outlet pipe, and a chlorine inlet and a hydrochloric acid inlet are provided on the brine inlet pipe.

[0015] Adopting the above technical solutions, compared with the prior art, the present utility model has the following advantages: Brine enters the mixing tower through the brine inlet pipe 5, and chlorine and hydrochloric acid are added for acidification and oxidation. The brine in the acidification and oxidation flows upward countercurrently in the tower. The brine passes through the gap between the first packing sheet 15 and the second packing sheet 16, enabling the brine to pass through evenly. At the same time, a number of flat parts 17 and a number of bending parts 18 are provided on the first packing sheet 15 and the second packing sheet 16, extending the residence time of the brine, and enabling the brine to carry out a preliminary mixing reaction with chlorine and hydrochloric acid in the packing 2.

[0018] By providing the packing 2, the forward rotating vanes 3 and the reverse rotating vanes 4, the residence time of the brine is extended, and double mixing makes the reaction more sufficient, with good production efficiency. Description of the Drawings
