Embodiment Construction

[0011] Embodiment of the present invention: large-scale iodine extraction device, such as figure 1 As shown, make a cylindrical tank body 1, connect the air outlet 2 on the top of the tank body 1, connect the discharge port 3 at the bottom of the tank body 1, install the feed inlet 4 on the top of the tank body 1, and install the air inlet 5 on the bottom of the tank body 1 The tank body 1 is made with a gas deceleration section 6, and the diameter of the gas deceleration section 6 is greater than the diameter of the tank body 1 below it. By increasing the cross-sectional area of ​​the tank body 1, the velocity of the airflow in the tank body 1 is slowed down. A fishnet liquid catcher 11 is also installed in the tank body 1 .

[0012] According to the applicant's test, the diameter of the gas deceleration section 6 is 1.5-2 times the diameter of the tank body 1 below it, which is more suitable. A dividing plate 12 with a grid is installed in the gas deceleration section 6, a...

Abstract

The invention discloses a large-scale iodine extraction apparatus, comprising a tank body (1), an air outlet (2) arranged on the top of the tank body (1), a discharge hole (3) arranged at bottom of the tank body (1), a feed inlet (4) arranged on an upper part of the tank body (1) and an air inlet (5) arranged on a lower part of the tank body (1). The apparatus is characterized in that the tank body (1) is provided with a gas deceleration segment (6), which has a diameter larger than that of the tank body (1) below the gas deceleration segment (6). According to the invention, the gas deceleration segment is prepared on the extraction apparatus, and air-flow speed is reduced by increasing a sectional area of the tank body; a fast-to-slow air-flow operation process is formed in the whole extraction tank to thoroughly mix the gas and the liquid, so as to substantially reduce volume of water vapor foam in an extraction fluid and gain a better extraction effect.

Description

technical field [0001] The invention relates to a large-scale iodine extraction device, which belongs to the technical field of fluid mixing and separators. Background technique [0002] Chinese patent 200820301317.9 discloses an iodine extraction extraction tower, which is used to extract iodine in the process of phosphoric acid production. The applicant found in use that due to the fast airflow entering the extraction tower, the mixing and contact time with the liquid is short, a large amount of water vapor foam is entrained in the extraction fluid, and the water vapor foam in the extraction fluid will be taken away when it is condensed. There is a large amount of iodine, so a fishnet liquid catcher must be specially set up at the top of the tower. In use, it is found that the fluorosilicate contained in the water vapor foam will precipitate and block the fishnet liquid trap, reducing the extraction effect. In addition, the volume of the extraction tower is too small, so...
