Embodiment Construction

[0024] The following description is essentially exemplary and not to limit the disclosure, application or use. It should be understood that in all of the figures, the corresponding reference numerals represent the same or corresponding components and features.

[0025] Embodiments of the present invention provide a recovery method of bromide in bromine containing bromine, including the following steps:

[0026] Step 10) Achieve bromine waste by water-containing exhaust gas is absorbed.

[0027] Step 20) After filtration of bromine waste, adjust the pH of bromine wastewater;

[0028] Step 30) The bromic waste of the pH is mixed with ozone to obtain a bromine mixture;

[0029] Step 40) Separate the bromine water mixture to give a monosen bromine.

[0030] The recovery method of bromide in bromide in the bromine containing bromide is absorbed by water-containing exhaust gas, so that bromide and water in the exhaust gas are hydrogen bromide, and bromide containing bromide is filtered ...

Abstract

The invention discloses a method and equipment for recycling bromine in bromine-containing waste gas. The method for recycling bromine in the bromine-containing waste gas comprises the following steps: (10) absorbing the bromine-containing waste gas with water to obtain bromine wastewater; (20) after the bromine wastewater is filtered, the PH value of the bromine wastewater is adjusted; step 30) mixing the bromine wastewater with the adjusted pH value with ozone for a preset time to obtain a bromine-water mixed solution; and step 40) separating the bromine-water mixed solution to obtain elemental bromine. According to the method and the equipment for recovering bromine in the bromine-containing waste gas, bromine in the bromine-containing waste gas can be recovered, the recovered bromine elementary substance can be directly returned to be used in a bromination reaction, and the consumption of bromine resources is reduced.

Description

Technical field [0001] The present invention is in the field of chemical technology, and in particular, a method and apparatus for recovering bromin in bromine containing bromine. Background technique [0002] The bromine-containing compound is an important fine chemical industry, widely used as a pharmaceutical intermediate, dye intermediate, gasoline additive, agricultural chemical, flame retardant, and developer. Babromin is an important raw material synthesizing bromine-containing compound, and is also an important raw material for the addition of brominated reactions in the synthesis of related pharmaceutical intermediates. The reactants and bromine monomers are obtained by replacing or additional reaction to the corresponding target product. The brominated reaction is involved in the production process of dispersion red 60. The bromine-containing water containing a large amount of bromide is inevitably produced during the bromination process. On one aspect of the emission o...
