Sleeve type chimney shake stopping method

Abstract

The invention relates to a sleeve type chimney shake stopping method, and belongs to the technical field of sleeve type chimneys. The sleeve type chimney shake stopping method comprises the following steps that S1, bases are installed, specifically, the bases are installed on the sides, close to an inner cylinder, of four platform steel beams; S2, a temporary shaking stopping assembly is mounted: the temporary shaking stopping assembly is mounted on one side, close to the inner cylinder, of the base, wherein the temporary shaking stopping assembly can play a role in restraining the inner cylinder; and S3, a permanent shake-stopping assembly is installed, specifically, after the inner cylinder is installed, the temporary shake-stopping assembly is detached, the permanent shake-stopping assembly is installed on the side, close to the inner cylinder, of the base, and the permanent shake-stopping assembly can fix the inner cylinder. The device has the effect of reducing shaking of the inner cylinder in the mounting process and the using process.

Description

technical field [0001] The present application relates to the field of telescopic chimneys, in particular to a method for preventing sloshing of telescopic chimneys. Background technique [0002] The telescopic chimney is widely used in thermal power plants. The telescopic chimney includes an outer cylinder and an inner cylinder. The inner cylinder is set inside the outer cylinder. A construction platform is installed inside the outer cylinder. The ends of the beams are connected and enclosed to form a rectangular space for the inner cylinder to pass through. [0003] At present, during the installation of the inner cylinder, the inner cylinder needs to be lifted, so the inner cylinder will shake, which increases the difficulty of construction, and after the inner cylinder is installed and put into use, during the smoke exhaust process of the inner cylinder, due to thermal expansion and contraction As a result, the inner cylinder will be deformed, which will cause the inner...

AI Technical Summary

Problems solved by technology

[0003] At present, during the installation of the inner cylinder, the inner cylinder needs to be lifted, so the inner cylinder will shake, which increases the difficulty of construction, and after the inner cylinder is installed and put into use, during the smoke exhaust process of the inner cylinder, due to thermal expansion and contraction effect, the inner cylinder will be deformed, which will cause the inner cylinder to shake

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the inner cylinder will shake during the installation of the inner cylinder and that the inner cylinder will shake due to thermal expansion and cold contraction after the installation is completed.
