s2, applying an electric field to the inert composite anode (14) and the inert composite cathode (15), enabling cations required in the first liquid storage tank (1) to move towards the cathode under the action of the electric field, enabling the cations to pass through the cation exchange membrane (16) and then enter the central generation chamber (10), enabling anions to be combined with hydrogen ions generated by the anode, enabling anions required in the second liquid storage tank (2) to move towards the anode under the action of the electric field, enabling the anions to pass through the anion exchange membrane (17) and then enter the central generation chamber (10), and enabling the cations to be combined with hydroxyl ions generated by the anode;
s3, after entering the central generation chamber (10), cations continue to move towards the cathode direction and remain in the central generation chamber (10), and meanwhile, anions continue to move towards the anode direction after entering the central generation chamber (10) and remain in the central generation chamber (10);
s4, combining the anions with cations from the anode generation chamber to generate required acid, alkali or salt.
10. The method for automatically generating the online double-ion acid-base salt solution by electrochemistry according to claim 9, wherein when the first liquid storage tank (1) and the second liquid storage tank (2) are arranged before the chemical reaction process, the exhaust holes (19) on the anode connector (8) and the cathode connector (9) are communicated, and the gas in the electrolysis chamber is discharged, so that the mother solution smoothly fills the electrolysis chamber, and the exhaust holes (19) are blocked after the mother solution is filled.
