Smelting furnace green smoke eliminating and purifying system

The invention discloses a smelting furnace green smoke eliminating and purifying system, and belongs to the technical field of waste gas purification, the smelting furnace green smoke eliminating and purifying system comprises a rotational flow tower, a spraying layer is arranged in the rotational flow tower, and the spraying layer comprises a spraying ring fixedly connected with the inner wall of a tower body and a spraying ring arranged on the inner side of the spraying ring; a plurality of first spraying holes which are obliquely arranged and face the spraying ring are formed in the spraying ring; and a plurality of spraying pipes are arranged on the spraying ring. According to the scheme, the spraying layer is mainly used for washing flue gas introduced into the cyclone tower, and soluble substances, hydrogen sulfide and the like in the flue gas are dissolved into circulating liquid; wherein the spraying ring is fixedly connected with the interior of the rotational flow tower and is in a relatively fixed
