Method for purifying acid gas by electrochemistry cooperating with microemulsion

The invention discloses a method for purifying acid gas by electrochemistry and micro-emulsion. According to the method, electrochemical reaction and micro-emulsion are organically coupled to cooperatively treat the acid gas to realize efficient absorption and purification of the acid gas. The micro-emulsion is dimethyl sulfoxide micro-emulsion, and is specifically prepared by uniformly mixing oil, dimethyl sulfoxide and a surfactant and dropwise adding a cosurfactant into the mixture until the mixture becomes transparent; compared with the prior art, the micro-emulsion disclosed by the invention has the advantages of simplicity in synthesis, small solvent consumption, large absorption capacity and good absorption effect; after combination with the electrochemical reaction process, the purification efficiency of the acid gas is further improved, when 10-25 KV voltage is applied, under the synergistic effect of the two, the purification efficiency of NO can reach 85% or above, the purification efficiency of SO
