The invention discloses a pretreatment device for high-temperature and high-humidity dust-containing industrial tail gas, which comprises a waste heat recovery system comprising a waste heat recovery heat exchanger and a conveying fan, and a tail gas washing system comprising a tail gas washing tower, the conveying fan is used for pumping the waste gas subjected to heat exchange into the tail gas washing tower; the filtering and cooling system comprises a filter and a closed water cooling tower, and the filter is used for filtering the dust-containing water of the tail gas washing tower to form filtered water introduced into the closed water cooling tower; wherein the closed water cooling tower is used for circulating the cooled filtered water into the atomization mechanism of the tail gas washing tower again. According to the pretreatment device for the high-temperature and high-humidity dust-containing industrial tail gas, waste heat recovery, cooling, dehumidification and dust removal treatment can be cond
