Hoisting method of loop reactor

Abstract

The invention provides a hoisting method of a loop reactor. The loop reactor comprises two straight pipes, a 180-degree elbow and a connecting beam, wherein the 180-degree elbow and the connecting beam are used for connecting the two straight pipes. The hoisting method of the loop reactor comprises the following steps: arranging a main lug at the top, close to the loop reactor, of the inner side of each straight pipe; arranging a tail holding lug at the bottom, close to the loop reactor, of the inner side of each straight pipe; connecting a first balance beam between a main hoisting hook and each main lug; a second balance beam is connected between a tail holding hoisting hook and each tail holding lug; the main hoisting hooks and the tail holding hoisting hooks are matched to change the loop reactor from a horizontal arranging state into an upright state; the loop reactor is vertically hoisted through the main hoisting hooks. The method hast the advantages that the deformation of theloop reactor in hoisting is small; mounting in place can be performed conveniently; moreover, the mounting quality accident is reduced.

Description

technical field [0001] The invention relates to the field of special equipment hoisting, more specifically, to a hoisting method of a loop reactor. Background technique [0002] In recent years, with the rapid development of petrochemical industry, polypropylene and coal-to-olefins in chemical products have also been highly valued by chemical companies, and one of the core equipment in the device - the loop reactor, due to its special structure, Usually, 4 or 6 slender tubes are connected through the active bolts of the intermediate connecting beam to form a well-shaped structure, which belongs to high flexibility equipment, and its hoisting and positioning has become the difficulty and focus of the installation process. At present, the hoisting method of the loop reactor generally uses slings to directly bind the cylinder body or set the main lifting lug and the tail lifting lug on the connecting beam. The operation workload is large during binding and hoisting, and the hig...

AI Technical Summary

Problems solved by technology

[0005] The invention proposes a hoisting method for a loop reactor, which solves the problems that the loop reactor is easily deformed due to unreasonable hoisting points, which is not conducive to the installation of equipment in place, and easily causes hoisting quality accidents
