Technical Field

The invention relates to a micro-space chimney shaking prevention device, and belongs to the technical field of chimney design and construction.

Background

The sleeve type chimney comprises a smoke exhaust inner cylinder (simply called 'inner cylinder') and an outer cylinder wall (simply called 'outer cylinder'), the outer cylinder is used as a bearing structure and bears the effects of wind load, earthquake, inner cylinder self-weight, horizontal displacement and the like, and the inner cylinder is used for discharging smoke with a corrosion effect; the sleeve chimney realizes two loads or functions of directly bearing external loads such as wind and the like and directly bearing the action of smoke; different structures are used for bearing loads or functions with different properties, so that functional division is achieved, and the safety of the outer cylinder structure and the maintenance of the inner cylinder are facilitated. However, the inner cylinder of the chimney has low rigidity and large deformation, so that a plurality of layers of horizontal shaking-stopping devices are required to be arranged along the height to restrain the horizontal displacement of the inner cylinder and ensure the normal operation of the inner cylinder.

The horizontal shaking-stopping device has a horizontal supporting effect on the inner barrel, and simultaneously needs to ensure the vertical free deformation of the inner barrel, namely the horizontal shaking-stopping device is a set of displacement control device for ensuring the limited displacement and the vertical free displacement between the inner barrel and the outer barrel, and is an indispensable displacement control device for a sleeve type chimney or a multi-pipe chimney.

The traditional horizontal shaking-stopping device mainly comprises a horizontal limiting sliding groove (referred to as a sliding groove for short) and a vertical sliding rail (referred to as a sliding rail for short), and the principle is that the vertical sliding rail fixed on an inner cylinder freely moves vertically along the sliding groove fixed on each layer of platform, but the horizontal direction is restrained by the platform and cannot shake at will, so that the relative consistency of deformation of each layer of platform is kept, and the shaking-stopping effect is achieved.

The premise for realizing the shaking prevention function is as follows: one or more layers of platforms are required on the inner side of the outer barrel of the chimney, and the platforms have enough installation and operation space to install the anti-sloshing device. However, for old chimney reconstruction projects, such as a common single-pass reinforced concrete chimney, when wet desulphurization reconstruction is carried out, in order to improve the diameter of the newly-added inner cylinder, reduce the flow rate of smoke and reduce the discharge amount of 'chimney rain' or smoke resistance, the diameter of the newly-added inner cylinder is required to be close to the inner diameter of the outer cylinder to the maximum extent, so that the clear distance between the inner cylinder and the outer cylinder on the upper part of the chimney is smaller, the installation space is limited, the sliding groove and the sliding rail are not spatially fixed and installed, the traditional shaking stopping device cannot be realized, and the implementation of the anticorrosion reconstruction of the single-cylinder.
