Gasification cooling flue for converter waste heat boiler

Abstract

The utility model relates to the technical field of cooling flues, and discloses a gasification cooling flue for a converter waste heat boiler, which comprises a gasification flue pipe, first fixing plates are fixedly mounted at the upper end and the lower end of the gasification flue pipe, bearing screws are arranged on the first fixing plates in a penetrating manner, and the first fixing plates are connected with expansion sleeves. And a second fixing plate is mounted on the outer surface of the expansion sleeve, and an extension plate is mounted on the second fixing plate. According to the gasification cooling flue for the converter waste heat boiler, the expansion sleeves are arranged at the upper end and the lower end of the gasification flue pipe, so that the expansion sleeves are not rigidly connected with the first connecting pipe and the second connecting pipe any more, namely the deformation effect caused by thermal expansion and cold contraction when the gasification flue pipe works can be reduced under the action of the expansion sleeves; the purpose of protecting the gasification flue pipe is achieved, the service life of the gasification flue pipe is prolonged, gas can be guided under the action of the guide plate and the attaching plate, and the situation that gas leaks out at all installation connecting positions is avoided.
