The invention discloses an arc panel double-hook channel demister which consists of multiple demister blades distributed in equal distance. Each demister blade consists of an inlet section, a demisting section and an outlet section, wherein the two ends of the demisting section are respectively connected with the inlet section and the outlet section, a primary hook plate and a secondary hook plate are respectively arranged on two side surfaces of the demisting section; the inlet sections of the two adjacent demister blades form an inlet channel; the demisting sections of the two adjacent demister blades form a demisting channel; the outlet sections of the two adjacent demister blades form an outlet channel; the inlet channel, the demisting channel and the outlet channel are sequentially communicated with one another; and in the demisting process, airflow sequentially passes through the primary hook plate and then the secondary hook plate. The demister disclosed by the invention has the characteristics of high comprehensive efficiency of removing droplets in the airflow and low flow resistance and is convenient to clean.
