The invention provides a hidden type haze removing device. The hidden type haze removing device comprises a tank, a haze removing mechanism arranged in the tank and used for removing haze, a regeneration mechanism arranged in the tank and matched with the haze removing mechanism, an opening and closing mechanism arranged at the opening position of the tank and used for opening and closing, a dirtdischarging mechanism arranged at the bottom of the tank, a drying mechanism arranged in the tank, and a control mechanism arranged on the side wall of the tank and used for coordinated control over the haze removing mechanism, the regeneration mechanism, the opening and closing mechanism, the drying mechanism and the dirt discharging mechanism. Through the mutual collaboration function between the mechanisms, the occupied area is small, manual maintenance is not needed, the structure is simple, underground components can be dried, and the phenomenon of structure damage of the components due to erosion caused by damp is reduced; and a good haze removing effect can be obtained, coordinated control can be conducted through the control mechanism, and the device can conduct efficient work moreorderly.
