Explosion-proof electrolytic dilute sulfuric acid concentration and recovery device

The utility model aims to provide an explosion-proof electrolytic dilute sulfuric acid concentration and recovery device which is characterized by comprising an explosion-proof cabin, a plurality of buffer support springs, a buffer sleeve, an electrolytic reaction cabin, an injection pipe, an injection sealing cover, two electrolytic columns, a controller, an exhaust pipe and a discharge pipe, a discharge valve is arranged in the middle of the discharge pipe; the whole device is of a double-layer sleeve type sealing structure, a buffer supporting mechanism is arranged on the outer side of the internal electrolytic reaction container, blasting impact force caused by overlong time and other abnormal conditions in the electrolytic process can be restrained, a dilute sulfuric acid solution is subjected to electrolytic reaction according to the electrolytic principle, and therefore water in the dilute sulfuric acid solution is reduced, and the service life of the dilute sulfuric acid solution is prolonged.
