description The utility model discloses tunnel ventilation equipment, and belongs to the technical field of ventilation equipment. In order to solve the problem that an existing product is lack of filtering treatment on exhausted air, the technical scheme is provided that the device comprises a device body composed of two oppositely-arranged ventilation parts, each ventilation part comprises an air blowing part and an air conveying part, each air conveying part is composed of a sleeve, a filter screen, a limiting assembly and an outer threaded column, the limiting assembly is arranged in the sleeve, and the filter screen is connected to the limiting assembly in a clamped mode through the outer threaded column. The loading assembly is additionally arranged in the air conveying sleeve, then the filter screen used for filtering air is loaded in a clamping and fixing mode, so that the content of impurities such as dust particles in the discharged air is reduced, the external construction environment is guaranteed, the practi
