Acrylic acid purification and light component removal tower

The invention relates to the technical field of acrylic acid purification, in particular to an acrylic acid purification and light component removal tower which comprises a tower body, and a material conveying opening is fixedly connected to the position, close to the center, of the side surface of the tower body; the liquid outlet is fixedly connected to the side surface of the lower end of the tower body; the exhaust port is fixedly connected to the top end of the tower body; and a separation mechanism; a separation mechanism is fixedly connected to the central position in the tower body and is used for accelerating the separation of methylbenzene, water and acetic acid in the acrylic acid crude solution. Acrylic acid solution is sprayed to the first separation cover and the second separation cover, the liquid flows downwards along the inclined planes of the first separation cover and the second separation cover, and the acrylic acid crude solution flows into the lower end from the upper end of the separati
