Boiler two-stage economizer overhauling platform

Abstract

The invention discloses a boiler two-stage economizer overhauling platform. The platform comprises an upper platform body for placing a two-stage economizer. The upper platform body is provided with a first mounting base. The portions, located on the left side and the right side of the first mounting base, of the upper platform body are provided with a first upper overhauling platform body and a second upper overhauling platform body. The first upper overhauling platform body and the second upper overhauling platform body transversely stride a boiler chimney. The lower platform body is arranged below the upper platform body. A first escalator is arranged between the lower platform body and the first upper overhauling platform body. A middle platform body is arranged between the lower platform body and the upper platform body. A second escalator is arranged between the lower platform body and the middle platform body. A third escalator is arranged between the middle platform body and the second upper overhauling platform body. A fourth escalator is arranged between the lower platform body and the ground. By means of the boiler two-stage economizer overhauling platform, personal can maintain or repair or operate an overhead boiler two-stage economizer conveniently, safer and more reliable device operation and maintenance are achieved, and labor efficiency is improved.

Description

technical field [0001] The invention relates to an inspection and maintenance platform, in particular to an inspection and maintenance platform for a boiler secondary economizer. Background technique [0002] The end of the boiler body is generally installed with a flue gas first-level economizer (coal economizer). The first-level economizer and the boiler are integrated in the design, and the maintenance platform of the first-level economizer also shares a maintenance platform with the boiler. Although the boiler is equipped with a first-level economizer, the exhaust gas temperature of the boiler is still high, and the flue gas will eventually be discharged into the atmosphere, resulting in energy waste. In recent years, boilers, especially fast-installed boilers, are not only equipped with economizers on the body, but also began to install specially designed secondary economizers on the boiler chimney. The secondary economizers can preheat the demineralized water supplemen...

AI Technical Summary

Problems solved by technology

However, the second-level economizer is installed on the boiler chimney. The second-level economizer is larger and heavier. It needs to be hoisted or installed with bottom support. The installation position is higher. The second-level economizer is generally installed on the horizontal section of the boiler chimney and installed in the boiler room. In the auxiliary machine room, it is not installed in the same room as the boiler (the installation in the same room spans too much and is not beautiful)

The installation position of the boiler chimney and the secondary economizer is relatively high, and the maintenance and operation of the secondary economizer body and its accessories require high-altitude operations. It is unsafe and inconvenient to use ordinary ladders

If the maintenance platform is installed, due to the large diameter of the chimney, the diameter of the boiler chimney in industrial enterprises is more than 1.0 meters, and the horizontal direction of the chimney prevents maintenance and operators from passing on the maintenance platform, especially the secondary economizer of 2 or more boilers For the maintenance platform, escalators should be installed separately from the ground to both sides or the middle of two or more second-level economizers, so that the escalators will take up a lot of space on the ground and increase costs, making installation difficult
