The utility model discloses a urea medium pressure absorption tower, which belongs to the technical field of urea production devices. The urea medium pressure absorption tower comprises a cylindrical tower body (15), a gas outlet (1), a gas inlet (9) and a liquid outlet (8), wherein the gas outlet (1) is arranged on a tower top, and the gas inlet (9) and the liquid outlet (8) are arranged on a tower bottom. The urea medium pressure absorption tower is characterized in that the tower body (15) comprises a bubble absorption segment (6) on the lower portion, a filler segment (5) on the middle portion and a rectifìcation segment (4) on the upper portion, wherein the lower portion of the bubble absorption segment (6) is provided with a gas distributor (7), the gas distributor (7) is communicated with the gas inlet (9), one side of the rectifìcation segment (4) is provided with a top ammonia water inlet (3), and a tower disc (11) is arranged in a rectifìcation tower (4). The urea medium pressure absorption tower has higher function of washing CO2 in gas, the content of the CO2 in the gas which comes out from the medium pressure absorption tower is in 5PPm, and the operation stability and the reliability of the medium pressure absorption tower can be increased.
