The invention relates to a primary smoke adjustable circular seam washing, water removing and mist removing integrated tower for a converter. The primary smoke adjustable circular seam washing, water removing and mist removing integrated tower comprises a tower body of a vertical structure. An adjustable circular seam heavy punch washer is arranged at the lower portion in the tower body. A smoke flow guiding pipe is arranged at the upper end of the adjustable circular seam heavy punch washer. The smoke inlet end of the smoke flow guiding pipe is connected with the smoke outlet end of a smoke pipeline. An outward type dust and water removing rotational flow plate is arranged in an annular space defined by a shell of the adjustable circular seam heavy punch washer, the outer wall of the smoke flow guiding pipe and the tower body. An outward type water and mist removing rotational flow plate I is arranged above the outward type dust and water removing rotational flow plate. A pressure water mist spray gun arranged in the downward direction is arranged at the upper portion of the smoke flow guiding pipe. Normally-open water mist nozzles are arranged at the upper end and the lower end of the outward type dust and water removing rotational flow plate and face the outward type dust and water removing rotational flow plate. The primary smoke adjustable circular seam washing, water removing and mist removing integrated tower is high in dust, water and mist removing efficiency; after smoke purification, the dust content is low, humidity is low and abrasiveness is small; and the maintaining workload of the system is greatly reduced, and the running reliability and safety of the system are improved.
