Waste incineration tail gas treatment device

The waste incineration tail gas treatment device comprises an external pipeline, a dust removal part, a first gas inlet pipeline and a water filtering part, a water inlet is formed in the upper portion of the left side of the water filtering part, a water outlet is formed in the lower portion of the right side of the water filtering part, and the right end of the first gas inlet pipeline extends into a solution in the water filtering part; a second air inlet pipeline is arranged at the upper end of the water filtering part, the right end of the second air inlet pipeline is communicated with the purification part and is connected with an exhaust tower after passing through the purification part, and the exhaust tower adopts a conical high-rise chimney. The water filtering part is filled with the calcium carbonate solution, dust and part of acid gas in the tail gas are further removed, pollution of the acid gas to air is reduced, the right end of the first gas inlet pipeline penetrates into the solution in the
