Method and device for producing sodium carbonate and/or sodium bicarbonate

The invention discloses a production method of sodium carbonate and/or sodium bicarbonate. (1) taking ammonia water and carbon dioxide as raw materials to prepare an ammonium bicarbonate solution for later use; (2) performing ion exchange on the ammonium bicarbonate solution to obtain a sodium bicarbonate solution; and (3) evaporating and concentrating the sodium bicarbonate solution to obtain crystals, namely sodium carbonate and/or sodium bicarbonate. Only two substances participate in the raw material reaction stage, the reaction process is single and simple, the controllability of the reaction process is high, and no other substances participate in the reaction, so that the reaction product is high in purity and good in quality; meanwhile, cation resin is used as a medium in the reaction at the ion exchange stage, the generated solution is a sodium bicarbonate solution with extremely high purity, the sodium bicarbonate solution generated by ion exchange does not need to be cleaned and purified, and sodium
