The invention discloses a novel blade type demister, and relates to the technical field of demisters, the novel blade type demister comprises a shell, a pre-separator and a separator, one side surface of the shell is provided with an air inlet, the top of the shell is provided with an air outlet, the air inlet is communicated with the pre-separator, the shell is internally provided with the separator, and an air flow outlet of the pre-separator corresponds to an air flow inlet of the separator. An air flow outlet in the top of the separator corresponds to the air outlet, a liquid outlet end at the bottom of the separator is communicated with a condensate discharge pipe, the separator comprises a silk screen collector and a blade separator, the silk screen collector is arranged on the outer side of the blade separator, the blade separator comprises a plurality of blades vertically arranged in the shell, and the blades are of a double-pocket type structure. The condition of secondary entrainment is avoided, and the separation efficiency is effectively improved; the utility model solves the defects of a silk screen filter separator, and has the effects of high efficiency, reasonable design, simple structure, convenience in cleaning, small volume, lower manufacturing cost, no energy consumption, small airflow pressure drop, reliability, stability and effective reduction of investment cost.
