The utility model discloses a skid-mounted ammonia liquor regeneration tower capable of being disassembled and assembled repeatedly. The regeneration tower comprises a tower top, a tower body and a tower bottom, wherein a carbon dioxide outlet, a wire mesh demister and a rich ammonia liquor inlet are arranged at the tower top; a lean ammonia liquor outlet is arranged at the bottom of the tower; a tower body comprises a first tower cylinder, a second tower cylinder, a third tower cylinder and a fourth tower cylinder from top to bottom; packing layers are arranged in both the first tower cylinder and the second tower cylinder; redistributors are arranged at the upper end and the lower end of each packing layer; a reboiler is arranged in the fourth tower cylinder; a hot coal oil outlet and a discharging port are formed in the wall of the fourth tower cylinder; and a hot coal oil inlet and an emptying port are formed in the lower part of the wall of the fourth tower cylinder. According to the regeneration tower, by means of the segmentation design of the tower body, the tower can be assembled and disassembled repeatedly for use and is easy to transport; according to the integrated design of the reboiler and the tower body, the size of the regeneration tower can be saved, a rich ammonia liquor containing carbon dioxide flows into the tower from the tower top, adsorbs most of the carbon dioxide through the packing layers, and then flows into the reboiler; and residual carbon dioxide is heated and separated out the temperature of 160 DEG C, the separation effect is good, and the regeneration efficiency is improved.
