Cooler for sampling water vapor of dry quenching boiler

The invention belongs to the technical field of water vapor cooling equipment, and discloses a cooler for water vapor sampling of a dry quenching boiler, which comprises a cooler mounting and dredging unit, one end of the cooler mounting and dredging unit is fixedly connected with a cooling module box; cooling units are hinged to the upper end and the lower end of the side wall, close to the cooler installation dredging unit, of an inner cavity of the cooling module box, and movable assemblies are movably clamped to the upper end and the lower end of the front side and the rear side of the inner cavity of the cooling module box. Through the cooperation of the cooling unit, the steam outlet pipe and other structures, the cooling contact area of the hot steam of the dry quenching boiler during discharging is increased, then the temperature of the hot steam can be gradually reduced after the hot steam passes through the first cooling plate, the hot steam is in a water drop shape, and through the design of the th
