Large-span suspended soot blowing platform

Abstract

The invention belongs to the technical field of boiler component structures, and particularly relates to a large-span suspended soot blowing platform structure which comprises a platform, two supporting frames, a hanging frame and a truss, wherein the lower part of the platform is supported by the supporting frames, and the truss is arranged between the supporting frames; one end of each supporting frame is fixed onto one corresponding vertical column, and the suspended end of the supporting frame is connected with the vertical column through the hanging frame, so that an upper-hanging and lower-bracket structure can be formed; the platform is composed of a plurality of platform frameworks, a horizontal support and a grid; the horizontal support is arranged on the side, close to a beam andthe vertical columns, of the platform; the platform frameworks are arranged side by side on the outer side of the platform; and the grid is laid above the platform frameworks and the horizontal support. According to the large-span suspended soot blowing platform structure provided by the invention, the brand-new supporting-hanging mode is adopted, no outer columns need to be arranged, the platform supporting structure is simplified, the large-span soot blowing platform layout demand is met, and the steel consumption and the civil engineering cost are reduced.

Description

Technical field [0001] The invention belongs to the technical field of boiler component structure, and particularly relates to a large-span suspended soot blowing platform. Background technique [0002] At present, the common domestic boiler cleaning methods mainly include mechanical rapping, shock blowing, steam blowing, etc. Mechanical vibration cleaning has a great impact on the service life and strength of the small header and pipes of the boiler, and the cleaning effect is poor; the effective soot blowing range of shock wave blowing is small, and it is only suitable for relatively narrow tail flue area. The safety is poor and the failure rate is high; the application range of steam soot blowing is large and the cleaning effect is good. However, due to the long length of the telescopic sootblower, it takes up a large space, so a large-span soot blowing platform is required. In order to arrange the large-span platform, the outer column is usually arranged on the outside of th...

Problems solved by technology

Mechanical vibrating soot removal has a great influence on the service life and strength of boiler small headers and pipes, and the ash removal effect is poor; the effective soot blowing range of shock wave soot blowing is small, and it is only suitable for relatively narrow tail flue areas. Poor safety and high failure rate; steam soot blowing has a wide range of applications and good ash cleaning effect, but due to the long length of the telescopic soot blower, it takes up a lot of space, so a large-span soot blowing platform needs to be arranged

In order to arrange large-span platforms, outer columns are usually arranged on the outside of the platform, and the platform is supported by beam-column structures. The setting of outer columns increases civil engineering costs, consumes a lot of steel, and costs a lot of investment.
