Belonging to the technical field of environmental protection, the invention discloses a boiler flue gas white smoke removal system. According to the boiler flue gas white smoke removal system, a cooling tower and a vortex tube are arranged between a flue gas condenser and a flue gas heater, and the flue gas condenser and the vortex tube are separated by the cooling tower, thus preventing reductionof flue gas condensation efficiency and heat exchange efficiency caused by mixing of cold air flow and hot air flow. A flow splitting chamber on the outer layer of the flue gas heater is arranged along the circumferential direction of an mixing chamber on the inner layer, the mixing chamber is communicated with the flow splitting chamber through flow guide pipes arranged on the surface of the mixing chamber, under the flow splitting effect of the flow guide pipes, the hot air flow generates uniform and stable thermal shunts, thus achieving uniform heating of flue gas in the mixing chamber; and the thermal shunts cannot press flue gas into a flue gas inlet pipeline due to too large air pressure, thus effectively preventing backflow of flue gas and improving the white smoke removal effect.
