Dry quenching primary deduster fragment hoisting method

Abstract

The invention provides a dry quenching primary deduster fragment hoisting method. The method is characterized by comprising the following steps: a hoisting preparation measures, b fragment assembly and hoisting of a lower frame and installation of cross beams, c ground assembly of fifth and sixth fragment frames of an upper frame, d hoisting of the fifth and sixth fragment frames of the upper frame, e installation of a cross beam at the top, f assembly and hoisting of seventh and eighth fragment frames and g adjustment and welding of the primary dedusting upper frame. The dry quenching primary deduster fragment hoisting method has the advantages of advanced technology, feasible operation, fast construction progress, high work efficiency, substantial reduction of overhead working time and overhead working safety risks and further easiness in control of construction quality.

Description

technical field [0001] The invention relates to a hoisting method, in particular to a piecewise hoisting method for a CDQ primary dust collector. Background technique [0002] With the society's urgent requirements for environmental protection and the vigorous implementation of national energy conservation and emission reduction policies, the coking industry has accelerated the elimination of backward production capacity and technological transformation. The coke dry quenching process is rapidly replacing the traditional wet coke quenching project. In recent years, the development of the coke dry quenching construction market has been significantly accelerated, and the construction period is required to be short, which puts forward higher requirements for the construction technology and quality of the coke dry quenching project. [0003] In the CDQ project, in the installation and construction of the CDQ primary dust collector, the columns, beams, diagonal braces, and second...

AI Technical Summary

Problems solved by technology

[0003] In the installation and construction of the CDQ primary dust collector in the CDQ project, the columns, beams, diagonal braces, and secondary beams were installed first, and then the platforms, wall panels, and brick supports were installed in turn. The construction period is long and there are many unscientific , Unreasonable places, there are a lot of high-altitude operations in the construction, the installation process is complicated, and the installation cost is high

[0004] Therefore the installation of the known CDQ primary deduster has the above-mentioned inconveniences and problems
