The utility model discloses a gas turbine inlet air filter device anti-freezing system which comprises a plurality of closed cooling water users and an anti-freezing coil pipe, the closed cooling water users are connected in parallel to form a user parallel connection unit, the user parallel connection unit is communicated with the anti-freezing coil pipe in series, and the anti-freezing coil pipe is communicated with the closed cooling water users. The anti-freezing coil pipe is communicated with the output end of the closed water pump through a water supply pipe, and the user parallel unit is communicated with the input end of the closed water pump through a water return pipe. After closed cooling water firstly passes through the anti-freezing coil pipe, the water temperature is reduced, and cooling of a closed cooling water user is facilitated. Due to the design that the user parallel unit is connected with the anti-freezing coil in series, the total flow of the closed water pump is reduced, the utilizatio
