Problems solved by technology

[0003] The traditional construction method of the conical straight chimney is formal construction, using the crane to hoist the processed conical wall panels in order from bottom to top, and then assemble and weld them. The disadvantages of the existing installation methods are that the large crane is occupied for a long time The site space requirements are relatively high; second, the construction height will gradually increase with the height of the chimney, and scaffolding needs to be erected as a construction platform, which requires high protection and high safety risks; third, the construction period is long and the construction period is tight

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as Figure 1-2 As shown, a quick installation method of a tapered straight chimney, including the following steps:

[0032] In the first step, mark the center point of the conical straight chimney on the bottom plate 5 with an ink line, draw a circle according to the center point as the center of the circle, and set six loose-clip flip-chip tops 3 on the bottom plate 5 symmetrically along the circumferential interval;

[0033] In the second step, ...

Abstract

The invention discloses a quick installation method of a conical straight chimney, which comprises the following steps: setting a loose clamp type flip top on the bottom plate; welding a plurality of buttresses on the upper end of the bottom plate; lifting the first wall plate To the upper end of the support pier, a main beam is placed on the upper end of the sliding brackets of the two symmetrical loose-clip flip tops. The two ends of the main beam are welded with auxiliary beams; The belt wall is lifted; the third belt wall is hoisted to the upper end of the pier by a crane, and welded to form the third belt wall; the second belt wall is hoisted by a crane between the first belt wall and the third belt wall, and the second belt wall The belt wall is welded with the first belt wall and the third belt wall; adjust the length of the auxiliary beam so that one end of the auxiliary beam is welded with the third wall plate, and repeat the steps until the conical chimney is assembled; remove the buttress and use the anchor bolts Connect and fix the conical chimney to the bottom plate; hoist the straight chimney to the upper end of the conical chimney for welding; remove the support pipe and perform anti-corrosion treatment on the conical chimney.

Description

technical field [0001] The invention relates to the technical field of chimney installation, in particular to a quick installation method for a tapered straight chimney. Background technique [0002] The chimney is a device that realizes flue gas emission after ultra-low emission treatment of industrial flue gas, and is widely used in the field of power generation and chemical industry. It generally includes straight chimneys and conical straight chimneys. Straight chimneys are generally installed on the top of the desulfurization tower. Conical straight chimneys are relatively rare. They are generally installed on the ground after desulfurization, denitrification and dust removal. [0003] The traditional construction method of the conical straight chimney is formal construction, using the crane to hoist the processed conical wall panels in order from bottom to top, and then assemble and weld them. The site space requirements are relatively high; second, the construction h...
