Bauxite sintering furnace dust-removing purification device

The invention discloses a bauxite sintering furnace dust-removing purification device. Smoke dust generated in the bauxite sintering process is intensively delivered into a spraying temperature-reducing dust remover to reduce temperature and remove dust so as to complete primary temperature-reducing and dust-removing process; the smoke dust processed with temperature reduction and dust removal is led into a lime water smoke dust filtering tank by a high-pressure blower to be atomized and purified by lime water so as to complete the second-time purification processing of the smoke dust; the smoke dust processed with secondary purification is led into an atomizing and purifying neutralization reaction tank, and a right amount of purification processing media are added into atomized water inside a main spraying system of the atomizing and purifying neutralization reaction tank to subject to neutralization reaction with harmful gases contained in the smoke dust so as to complete the third-time dust-removing and p
