Abstract
The invention discloses a sealing device for a waste gas converting system. The sealing device is characterized in that a compression device, an upper pressing piece, a lower pressing piece and filler are included, the part between the upper pressing piece and the lower pressing piece is filled with the filler, and the compression device is arranged above the upper pressing piece; and the compression device comprises a drive device and compression plates connected with the drive device. According to the sealing device for the waste gas converting system, the filler is extruded and deformed through the compression device, the upper pressing piece and the lower pressing piece, and therefore a gap between a skirt and a movable chimney cover can be sealed, and the structure is more convenient to operate. According to the sealing device for the waste gas converting system, by means of a steel plate and a flexible plate, equipment can be prevented from being damaged, and the service life of the equipment is prolonged. According to the sealing device for the waste gas converting system, due to the fact that two or more compression plates are arranged, compression can be carried out in different directions, and the compression strength can be remarkably improved.
Description
Technical field
The present invention relates to a kind of seal arrangement, particularly relate to a kind of sealing device for waste gas conversion system used in steelmaking converter.
Background technique
Pneumatic steelmaking ratio juris be in rich carbon melt oxygen blast with removing carbon wherein, in oxygen blast process, carbon burning produces carbon monoxide and carbon dioxide, the inlet of converter waste gas flow and air is depended on by the amount of gas of waste gas system and composition, during the course, must by limiting the air quantity entered from the gap between converter mouth and exhaust system, and between portable skirt and chimney mantle, sealed the reaction suppressing carbon monoxide, the sealing in existing gap between skirt and portable chimney mantle, mainly realized by nitrogen injection or steam, nitrogen and steam inject between two adjacent flanges, sealing is realized by overvoltage.
Summary of the invention
