Waste heat recovery device of diesel generating set

The utility model discloses a waste heat recovery device of a diesel generating set, belongs to the technical field of waste heat recovery of generating sets, and aims to solve the problem that in the long-term use process, a certain amount of scale is easily accumulated and attached to the inner wall, close to a generator shell, of a heat conduction shell, so that the heat conduction effect of the heat conduction shell can be reduced. Comprising a generator body, a heat conduction cylinder is fixed to the top of the peripheral face of the generator body, a water storage bin is formed in the heat conduction cylinder, a first heat preservation pad is glued to the peripheral face of the heat conduction cylinder, and a second heat preservation pad is glued to the top of the heat conduction cylinder; according to the diesel generating set waste heat recovery device, scale attached to the inner wall of the heat conduction cylinder and close to one side is separated from the inner wall of the heat conduction cylind
