Abstract

The in'vention discloses a waste heat boiler for recovering waste heat generated by the incineration of wastes from a polysilicon purification process, which comprises a circulating pump, a drum, a boiler support and a boiler body arranged on the boiler support, wherein the boiler body comprises a boiler closed shell, a smoke inlet shutter, a smoke outlet shutter, a high temperature evaporator, afirst low temperature evaporator, a second low temperature evaporator, a dust removing device and a dust hopper, and the boiler closed shell has a symmetrically-distributed and mutually-independent double flue structure consisting of a left film-type water-cooled blast furnace wall, a right film-type water-cooled blast furnace wall and a 'horizontal H'-shaped frame sealed partition wall. With thedesign of symmetrically-arranged double flues, the boiler can operate through a spare flue when a flue on one side fails to work so as to ensure normal operation. The boiler is a waste heat boiler for recovering waste heat generated by the incineration of the wastes from the polysilicon purification process, which is in accordance with the properties of polysilicon smoke, meets technical requirements and is easy to repair and high in operational stability.
