A method and a device for regulating waste organic polymer material pyrolysis products are provided. Waste organic polymer materials are uniformly mixed with a composite auxiliary agent for removing harmful elements at a mass ratio of 90:10 and subjected to pyrolysis at 400-450° C. Resulting primary pyrolysis products are brought into contact with catalysts and placed at a temperature of 550-800° C. to obtain pyrolysis products. The invention reduces the sulfur and chlorine content in pyrolysis oil products by more than 85%. Through the reverse flow of the waste organic polymer materials relative to the catalysts during pyrolysis, and the regulation of catalyst temperature, the invention achieves increased production of low-carbon olefins and aromatics in the pyrolysis products, significantly improving the economic value of the pyrolysis products and promoting technological innovation in the pyrolysis industry for materials such as waste rubber and waste plastic.
