The utility model provides a boiler dryness cooling device. The boiler dryness cooling device comprises a spiral cooling pipe and a cooling tank, the spiral cooling pipe is arranged in the cooling tank, an inlet and an outlet of the spiral cooling pipe extend out of the cooling tank, the inlet of the spiral cooling pipe is communicated with a sampling water inlet pipeline, the outlet of the spiral cooling pipe is communicated with one end of the sampling water discharge pipeline, a cooling water inlet joint and a cooling water outlet joint are arranged on the cooling tank, the cooling water inlet joint is communicated with an inlet pipeline, the cooling water outlet joint is communicated with an outlet pipeline, the other end of the sampling water discharge pipeline is communicated with the outlet pipeline, a sampling valve is arranged on the sampling water discharge pipeline, and an one-way valve is arranged on the sampling water discharge pipeline between the sampling valve and the outlet pipeline. According to the boiler dryness cooling device, a sampling trough and a water collecting tank are omitted, zero discharge of cooling water and sampling water is achieved, heat of exchange of the cooling water is effectively recycled, and the cooling effect is quite remarkable.
