The invention discloses a reaction apparatus for ozone tail gas absorption. The apparatus employs a stacking tower structure, and the tower body comprises a first absorbing tower and a second absorbing tower. An inner chamber is arranged between the first absorbing tower and the second absorbing tower, and an arc baffle plate constitutes the inner chamber roof; the first absorbing tower bottom isequipped with an air distribution plate communicating with a bottom air chamber which communicates with the outside through an air inlet pipe; an air distribution pipe on the second absorbing tower bottom communicates with the inner chamber through an air-guide tube, wherein the air-guide tube is in an upside-down U-shape tube structure, and one end of the air-guide tube communicates with the inner chamber through an opening on the arc baffle plate, and the other end of the air-guide tube communicates with the air distribution pipe on the second absorbing tower bottom. The invention can be widely applied to absorption and processing of ozone tail gas, and has the advantages of a simple process, small land occupation, good tail gas absorption and processing effects, low costs and zero catalyst regeneration.
