The invention has the advantages that:
(1) when the flue gas passes through the liquid drop removing device at a certain flow velocity, due to the inertia impact action of the gas, water drops collide with the corrugated plate and are attached to the surface of the corrugated plate, the dispersion and gravity settling action of the water drops on the surface of the corrugated plate enable the small liquid drops to be converged into large liquid drops, and the liquid drops slide down from the corrugated plate when the gathered liquid drops reach the condition that the gravity generated by the gathered liquid drops exceeds the resultant force of the rising force of the gas and the surface tension of the liquid, so that the effect of removing the liquid drops is realized;

(3) the smoke guide plate is arranged, and the outlet of the smoke guide plate faces the bottom end of the chimney, so that the direct washing of smoke on the liquid drop removing device is avoided;
(4) because the small droplets in the flue gas contain impurities such as sulfate, dust and the like, the droplet removing device can generate scale when running for a long time, therefore, a differential pressure gauge for measuring the pressure loss of the droplet removing device is arranged, whether spray flushing is started or not is determined according to the pressure displayed by the differential pressure gauge, and the normal use of the droplet removing device is ensured;
(5) and the ground at the bottom end of the chimney is a slope surface, so that liquid drops and spray water converged by the drain pipe can be conveniently discharged.
