The detachable heat preservation device comprises water-cooled wall heat preservation layers and a detachable heat preservation box, the water-cooled wall heat preservation layers are installed on the outer sides of water-cooled wall pipes, and the detachable heat preservation box is installed between the water-cooled wall heat preservation layers. The detachable heat preservation box is arranged at the welded junction of the water-cooled wall tube of the boiler, when the welded junction of the water-cooled wall leaks, the detachable heat preservation box is directly taken out, the detachable heat preservation box is installed again after dew point treatment is completed, repeated use is achieved, a large-area heat preservation layer does not need to be dismantled, and dismantled heat preservation waste is not generated; when other parts of the water cooling wall leak, the detachable heat preservation box can be directly taken out, the general leakage part of the water cooling wall tube is determined, then th
