Abstract

Disclosed in the present invention is a production method for sodium bromide. Bromine-containing brine is directly used as a raw material, so that the price is low; three absorption towers that are connected to each other are used for absorbing blown-out bromine, so that bromine can be more thoroughly absorbed, the waste of the raw material is avoided, and it is also prevented that unabsorbed bromine overflows into air to pollute the environment; a fan providing a power source for bromine-containing air entering the absorption towers also provides power for bromine blowing of an oxidized liquid, and thus, the whole cyclic operation is closed, bromine cannot overflow into the external environment, it is also ensured that bromine can be circularly absorbed, the yield rate of a product is improved, impurities such as sodium bromate cannot be produced in the whole reaction process, technological treatment is simpler, and the process period is shortened.
