Problems solved by technology

The traditional installation method of the water-cooled wall of the waste heat boiler is that the water-cooled wall is hoisted in a single piece after the installation of the boiler steel structure. Pre-stored near the installation location, the construction efficiency is low, and it is not conducive to the control of the construction progress

Embodiment Construction

[0029] The present invention is further illustrated by specific examples below.

[0030] A construction method for penetrating the integral top of the water wall of a waste incineration power generation waste heat boiler, comprising

[0031] Step 1. Production of water wall tooling platform:

[0032] Two I-beams are used to make 4 sets of water walls at the same time. The height of the tooling platform from the ground is at least 1 meter. Each leg of the tooling platform is supported on a concrete pier or concrete pavement to prevent the platform from sinking and deforming. Adjust the elevation of the tooling platform to ensure levelness;

[0033] Step 2. Assemble the water wall in sections on the ground:

[0034] The limit device is welded on the water wall tooling platform, and the limit device is 4 meters apart for the assembly and adjustment of the water wall; when the water wall is assembled, the length, width and diagonal dimensions are mainly adjusted to ensure the geometric siz...

Abstract

The invention relates to a construction method for enabling water-cooling walls of a refuse incineration power generation waste heat boiler to integrally penetrate from a top. The construction method is characterized by comprising the following steps: step 1, manufacturing a water-cooling wall tool platform; step 2, assembling the water-cooling walls in a segmental mode on ground; step 3, mounting collecting boxes and the water-cooling walls in pairs; step 4, mounting rigid beams; step 5, enabling the water-cooling walls to integrally penetrate from the top; step 6, hoisting the water-cooling walls to the positions; and step 7, arranging an overhead row of tubes in pairs. With the adoption of a mounting method for the water-cooling walls of the waste heat boiler, water-cooling wall hoisting times and quantity of the overhead row of tubes welded in pairs are reduced, pipeline butt-welding quality control is convenient, the problem that part of the water-cooling walls are difficult to put in positions after a boiler steel structure is mounted can be efficiently solved, the construction period is effectively shortened, and potential safety hazards caused by overhead mounting operation and welding operation are further reduced. Meanwhile, a special clamping device for ground pipeline aligning and an overhead pipe row aligner are applied, so that working efficiency and project quality are effectively improved.

Description

Technical field [0001] The invention relates to a method for installing a water-cooled wall of a waste incineration waste heat boiler system, in particular to a construction method in which the entire top of the water-cooled wall of a waste incineration power generation waste heat boiler is penetrated. Background technique [0002] With the rise of domestic waste incineration and environmental protection power generation business, higher requirements have been put forward for the installation of waste heat boilers for waste incineration power generation. The traditional installation method of the water wall of the waste heat boiler is that the water wall is installed in a single piece after the installation of the boiler steel structure. The adjustment of the high-altitude assembly is inconvenient, the welding quality cannot be guaranteed, the working surface cannot be deployed, there are many potential safety hazards, and the rigid beam must Pre-stored near the installation loca...
