Abstract: A coupled medium-low temperature flue gas processing apparatus for fly ash washing includes a reactor and scraping rings. In the present disclosure, arranging the scraping rings can scrape the fly ash adhered to the inside of the reactor and bring the scraped fly ash into a mixing liquor to prevent the fly ash from adhering and accumulating, which not only results in the decrease of the fly ash content participating in the reaction, and the difficulty to react with water completely, but also the fly ash adhered to the inside of the reactor will form a thick object after mixing with the water, once the thick object is dried, the adhesive capacity thereof is greatly enhanced.
