This paper makes an approach to the floating ring seal device of the large rotary furnace of chemic industry in existing, the existing structure is improved to be a new combined seal device consisting of discharge-helix and floating ring and radial labyrinth. The seal effect is ameliorated, the abrasion value of seals is reduced and its life is prolonged. Thereby the product grade is heightened, energy saving and emission reduction. Which has referential function for analogous with improvement of seal device.
