Production system for producing bromide by neutralization method

Abstract

The invention discloses a production system for producing bromide by a neutralization method, and belongs to the technical field of inorganic bromide production. The system comprises a mixed reactor,a blow-out tower, an absorption tower, a dehydration tank and a distillation tower which are sequentially connected through a pipeline. The top of the distillation tower is connected to one end of a condenser, the other end of which is connected to a hydrobromic acid storage tank; the hydrobromic acid storage tank is connected to a bromination reactor, and the hydrobromic acid storage tank is connected to the bromination reactor through a hydrobromic acid pipeline; and the top of the bromination reactor is connected to a lye pipeline. The system can continuously produce hydrobromic acid from brine and increase the concentration of hydrobromic acid by dehydration and distillation to meet the requirements of metal bromide production.

Description

technical field

[0001] The invention relates to the technical field of inorganic bromide production, in particular to a production system for producing bromide by neutralization. Background technique

[0002] Bromides generally refer to binary compounds containing bromine in the -1 oxidation state, including metal bromides and non-metal bromides. Common metal bromides are: sodium bromide, manganese bromide, barium bromide, copper bromide, magnesium bromide, thallium bromide, mercury bromide and so on. Metal bromide has a wide range of uses, such as: sodium bromide is used to make photosensitive film, used as a diuretic and sedative in medicine, and has the effect of strengthening the inhibition process of the cerebral cortex. It is also used as a chemical reagent; potassium bromide is used for medicine as a nerve sedative, for photography to make silver bromide paper, and also for engraving and lithography, for making special soap, for analytical reagents, for spectroscopic...
