Anti-air leakage structure of end part of steel and iron plant ring cold machine smoke hood

Номер: CN0101660867A
Принадлежит:

The invention discloses an anti-air leakage structure of an end part of a steel and iron plant ring cold machine smoke hood, which comprises more than two hinge turning plates, a sector plate is welded on the hinge turning plate between each hinge turning plate; or the sector plate is respectively welded at two sides of each hinge turning plate; the central angle of the sector plate is 60 degrees;and a cold gap between two adjacent sector plates can be arranged to 5mm. The anti-air leakage structure of the end part of the steel and iron plant ring cold machine smoke hood not only decreases air leakage rate, especially solves the air leakage of an included angle existing when the turning plates are not parallel, thus lightening the influence of air leakage on smoke quality, improving smokeutilization quality, and causing the smoke temperature to avoid impact of uncertain air leakage and a whole waste heat generating system to more stably and efficiently operate.
