System and method for efficiently preparing taurine continuously

A system for continuous production of taurine, comprising:

• a reaction unit configured to prepare a solution containing an alkali metal taurinate by an ethylene oxide process;
• a solution storage unit configured to store the solution containing alkali metal taurinate from the reaction unit;
• an ion exchange unit comprising a plurality of acid cation exchange resin columns, configured to input the solution containing alkali metal taurinate from the solution storage unit into the plurality of acid cation exchange resin columns in activated state to obtain the taurine through an acidification treatment, followed by activating a portion of the plurality of acid cation exchange resin columns by a first activation manner using sulfurous acid and obtaining a solution containing alkali metal bisulfite, and activating the remaining portion of the plurality of acid cation exchange resin columns by a second activation manner using sulfuric acid, wherein the first and second activation manner are performed on a same acid cation exchange resin column alternatingly or on different acid cation exchange resin columns;
• and
• a dispensing unit connected to the solution storage unit and the ion exchange unit, the dispensing unit being configured to adjust an amount of the solution conveyed from the solution storage unit to each of the plurality of acid cation exchange resin columns in the ion exchange unit.
