The invention relates to the technical field of dust removal of bag-type dust removers, in particular to a pollution-free dust removal electromagnetic pulse valve capable of collecting and utilizing chlorine gas for blowback and a method. The electromagnetic pulse valve is an electromagnetic pulse device special for chlorine, and chlorine is used as a reverse blowing working medium of the electromagnetic pulse valve; under the condition that the chlorine concentration is not influenced, the pulse dust cleaning effect is achieved; the valve body is made of chlorine corrosion resistant materials, the volume of the rear air chamber (7) is larger than that of the front air chamber (5), and the air pressure acting force of the rear air chamber (7) is large. A front diaphragm (3) is arranged between the front air chamber (5) and the rear air chamber (7), and a rear diaphragm (6) is arranged on the side of the rear air chamber (7); the front gas chamber (5) and the rear gas chamber (7) are respectively provided with
