Problems solved by technology

The result of poor sealing is that the untreated gas directly enters the pure area, which directly leads to the decrease of dust removal efficiency and performance.
[0006] Through further analysis, for the original air duct sealing device, the thermal deformation of the metal is small below 150°C, and it can be used as a sealing device. Larger working conditions, can not guarantee a good mating seal

Embodiment Construction

[0015] The solution of the present invention is based on the idea that the stress of the metal during thermal deformation is extremely large, and it is difficult to achieve the effect of sealing if it is rigidly connected. The use of ceramic fibers with excessive elasticity can eliminate thermal stress, and at the same time filter dust like a sponge to achieve the result of not reducing the dust removal efficiency.

[0016] As shown in the accompanying drawings, the present invention mainly consists of a gland 1, a gasket 2, a sealing packing, a steel pipe 4 and a fixed hook 5 and the like. Under the condition of ensuring the installation accuracy of the air guide pipe, weld the steel pipe 4 on the upper support plate 7 of the dust collector, use ceramic fiber 3 (temperature resistance greater than 1000°C) as the sealing packing, after compaction, assemble the gasket 2, and then assemble the gland 1 , by fixing the hook 5 to locate and fix the gland 1 . The function of the ga...

Abstract

The invention discloses a tubular compressing device, which includes a gas guide tube (6) and a duster upper support plate (7) for supporting the gas guide tube (6), wherein a steel pipe (4) is sleeved outside the gas guide tube (6); the steel pipe (4) is fixed on the duster upper support plate (7); the space formed by the steel pipe (4), the gas guide tube (6) and the duster upper support plate (7) is filled with ceramic fiber (3); and a gland (1) is also fixed on the steel pipe (4) and encloses the space filled with the ceramic fiber (3). By adopting the structure, when the duster undergoes the high-temperature stress deformation, as the gas guide tube (6), the duster upper support plate (7) and the steel pipe (4) are in clearance fit, the stress concentration is avoided, meanwhile, the upper-lower space gas shifting is avoided under the action of the ceramic sealing material, and the sealing effect is improved.

Description

technical field [0001] The invention relates to a tube-type pressing device used for sealing between an air guide pipe and an upper supporting plate of a dust collector in the field of dust collectors. Background technique [0002] Since 2000, in my country's steel coking industry, due to the popularization and application of chain grate machine-rotary kiln pellet technology and coking CDQ technology, there has been a large demand for the important equipment in the process of dust removal-gas multi-tube dust collector. Due to the special requirements of the process, the dust removal efficiency of the multi-tube dust collector is extremely high, and at the same time it meets the long-term safe and stable operation requirements. [0003] For multi-tube dust collectors, ensuring high dust removal efficiency and long-term stable operation under operating conditions are the criteria for judging the design of multi-tube dust collectors. [0004] The gas multi-pipe dust collector ...
