Problems solved by technology

[0002] In recent years, with the rapid development of petrochemical industry, polypropylene and polyethylene in chemical products have also been highly valued by chemical companies, and one of the core equipment in the device - the loop reactor, although not heavy, but Its shape is long and slender, with low rigidity and high flexibility. How to control the deformation of the equipment during the hoisting process has become the difficulty and focus of the equipment hoisting process.
[0003] In petrochemical plants, the main lifting lugs and tail lifting lugs are usually installed at the head and tail ends of the equipment for equipment hoisting. If this method is simply applied to the hoisting of the loop reactor, then the loop reactor The middle part of the tube reactor will have a large deflection and deformation due to its own weight and the lifting point at the end, which is extremely unfavorable to the equipment body and may easily cause quality accidents in lifting
[0004] In order to better control the deformation of the loop reactor during the hoisting process, the main lifting lug and the sliding tail lifting lug can be used to approach the equipment center (center of gravity), which can reduce the deflection and bending moment of the loop reactor due to its own weight , so as to reduce the deformation during the hoisting process; however, if the main lifting lug is too close to the center of gravity, the equipment will be easily deflected and the verticality is not good during the hoisting and positioning process, which is not conducive to the positioning of the equipment

Embodiment Construction

[0016] The present invention will be described in detail below in combination with specific embodiments.

[0017] The loop reactor of polypropylene and polyethylene devices is long and slender, with low rigidity and high flexibility. When hoisting, in order to reduce deformation, first, the main hoisting point should be equipped with multiple hoisting points, generally four hoisting points ( Lifting lugs) are appropriate, and the four lifting points are easy for the equipment to be vertical and easy to be in place; the second is that two guide pulleys must be set on the main lifting point (four lifting lugs), so that every two lifting lugs are transferred by the guide pulleys And the force is even.

[0018] For the loop reactor of polypropylene and polyethylene devices, the length is within 40m, the main lifting point can be set at about 5m from the head, and the tail lifting point can be set at about 10m from the tail; the lifting lug at the main lifting point It should be s...

Abstract

The invention relates to a binding and hoisting method for a loop reactor. In petrochemical installations, the main lifting lug and the sliding tail lifting lug are usually installed at the head and tail ends of the equipment for equipment hoisting, which is prone to large deflection and deformation. In the present invention, four hanging points are set on the loop reactor, and the Ф39 steel wire rope is wound and bound to the hanging points of the loop reactor, and each hanging point is wound and bundled 7 times, and a 50T snap ring and a main hanger are selected for each hanging point. Rope connection; the main lifting rope is made of Ф83mm steel wire rope buckle, two on each ring pipe, the first Ф83mm rope buckle of each ring pipe is connected with two 50T snap rings, and a 150T single tackle is hung on the rope buckle. The single tackle is connected with a 150T snap ring, the second Ф83mm rope buckle and a hook. The hoisting method of the invention can greatly reduce the deflection and deformation of the equipment caused by its own weight, prevent the equipment from deflecting, and ensure the hoisting quality and hoisting efficiency.
