Abstract
The invention relates to the steelmaking converter equipment technical field, in particular to a movable smoke hood sealing device of a steelmaking converter. The movable smoke hood sealing device overcomes the defects that the prior converter movable smoke hook sealing technology has high nitrogen consumption and high nitrogen content in coal gas. The invention provides a movable smoke hood sealing device of the steelmaking converter. The movable smoke hood sealing device comprises a movable smoke hood, a movable smoke hood protective flange and a fixed flue; the movable smoke hood and the movable smoke hood protective flange which is welded with the movable smoke hood into a whole are concentrically sleeved on the outer wall of the fixed flue; the outer wall of the fixed flue is annularly provided with a follow-up sealing ring; and the follow-up sealing ring is arranged on the top of the movable smoke hood protective flange. The movable smoke hood sealing device uses a simple mechanical method to solve the sealing problem of the movable smoke hood of the converter, reduces the nitrogen content in the coal gas and improves the quality of the coal gas.
Description
Technical field
The present invention relates to the steel-making converter equipment technical field, be specifically related to a kind of steel-smelting converter movable smoke hood sealing arrangement.
Background technology
Present known converter movable hood adopts the nitrogen-sealed technology, is the modern technique that replaces sealing structure for water, but still exist converter movable hood and converter fixedly between the flue gap big, nitrogen consumption height, the high defective of nitrogen content in the coal gas composition.
Summary of the invention
In order to overcome the high defective of nitrogen content in existing converter movable hood nitrogen-sealed technology nitrogen consuming amount height, the coal gas, the invention provides a kind of steel-smelting converter movable smoke hood sealing arrangement, this technology is Maintenance free not only, and nitrogen consumes little, use cost is low, and can improve the quality that reclaims coal gas.
In order to achieve the above object; the invention provides a kind of steel-smelting converter movable smoke hood sealing arrangement; comprise movable gas hood, movable gas hood protection flange and fixing flue; movable gas hood and the movable gas hood protection flange concentric locking collar that is welded as a whole with it are loaded on fixedly flue outer wall; its special character is: described fixedly flue outer wall is around being provided with the Follow-up seal circle, the Follow-up seal circle be arranged on movable gas hood protection flange above.
Above-mentioned Follow-up seal circle is made up of around the monomeric servo sealer of arranging plurality of continuous; Described servo sealer bottom is provided with the sealing steel plate, and the overwhelming majority in space between fixedly flue outer wall and the movable gas hood protection flange is blocked, and makes the leakage area of flue gas reduce to minimum; Fixedly flue outer wall is close in described servo sealer inboard, and described servo sealer is fixedlyed connected with the movable gas hood protection flange outside by the retaining thread web member.
Above-mentioned servo sealer is inboard to be provided with roller frame with fixing flue outer wall contact position; the power of the vertical direction of flue outer wall is unlikely to too big to make servo sealer be subjected to fixedly, thereby guarantees that sealing steel plate and movable gas hood protection flange keep relation of following up on vertical surface.
Level is provided with spring assembly between the retaining thread web member in the roller frame of above-mentioned servo sealer inboard and the servo sealer outside, spring assembly is pushed the roller frame and the sealing steel plate of servo sealer to fixedly flue outer wall, make the sealing steel plate on horizontal plane, form relation of following up with fixing flue, thus the assurance sealing effectiveness.。
Above-mentioned spring assembly is provided with guide frame, keeps the rigidity of spring assembly on vertical surface, thereby guarantees that sealing steel plate and movable gas hood protection flange keep relation of following up on vertical surface, thereby guarantees sealing effectiveness.
The plane of above-mentioned sealing steel plate is a sector shape.
Compared with prior art, the beneficial effect of the present invention's generation is as follows:
The present invention solves the converter movable hood sealing problem with simple mechanical means, reduces a nitrogen content in the coal gas, improves gas quality.
