Embodiment 1

[0035] Example 1, such as Figure 1-2 As shown, the structure can form a single integral double U-shaped loop reactor through the structure of three sets of elbows 11, four sets of straight tube sections 12 and wide flange reinforcement beams 13, and multiple sets of double U can be erected according to site requirements. Type loop reactor equipment, and each set of equipment is equipped with a support reinforcement mechanism 2 and a balance positioning mechanism 3 as an auxiliary reinforcement and balance system, so as to ensure that the on-site construction process of each set of equipment is the same, and the equipment requirements and work processes do not require change.

Embodiment 2

[0036] Example 2, such as figure 2 As shown, after the equipment is hoisted upright, the bushing 21 can be slid on the outside of the straight cylinder section 12 to descend, so that the bushing 21 drives the connecting arm 22 and the fixing platform 23 to descend, thereby driving the anchor bolts through the fixing platform 23 24 is inserted into the ground for pouring and fixing, and the two sides of the device can be reinforced, which greatly improves the positioning effect and balance of the device.

[0037] Working principle: The device can form a double U-shaped ring tube reaction equipment through the structural combination of three sets of elbows 11, four sets of straight cylinder sections 12 and wide flange reinforcement beams 13, thereby improving the overall rigidity of the equipment and reducing the occupied area. And determine the assembly, reinforcement and hoisting scheme according to the site conditions, then assemble the equipment in a horizontal state, and t...

Abstract

The invention discloses a modular construction method for a double-U-shaped loop reactor. The modular construction method comprises the following steps that firstly, four groups of straight cylinder sections, three groups of elbows and a wide flange reinforcing beam are fixedly connected and assembled to form a double-U-shaped loop reactor system; and in order to ensure the equipment assembly precision in the assembly process, the lower portion of the bottom of a body can make contact with the ground for positioning through a balance positioning mechanism, equipment is leveler and firmer and prevented from deforming, and laser leveling equipment is adopted for precision control in the assembly process. According to the modular construction method for the double-U-shaped loop reactor, a modular equipment assembly precision control technology, a modular hoisting anti-deformation reinforcing technology and a modular hoisting hoisting point balance technology are respectively formed through mutual cooperation of a double-U-shaped loop reaction mechanism, the balance positioning mechanism and a hoisting point balance mechanism, so that the equipment utilizes the balance positioning mechanism as a simple support, and the equipment is ensured to be levelled and firmed. Overall alignment of the equipment is facilitated, and the hoisting stability of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of loop reactors, in particular to a modular construction method for double U-shaped loop reactors. Background technique [0002] As the core equipment for chemical reaction, the loop reactor has a unique structural form. The loop reactor consists of 4 slender straight cylinder sections with a length of 39 meters, an inner diameter of Φ609.6mm, and a jacket with an inner diameter of Φ690. The outer tube consists of a straight cylinder section, three 180° elbows, and several connecting beams. The weight of the equipment is about 145 tons, which is super long and overweight. [0003] At present, domestic loop reactors are hoisted in two ways: integral or fragmented. When two cylinders are combined for hoisting, this hoisting process for assembling equipment requires greater site requirements. The two cylinders are combined into a sheet-like structure as a whole The rigidity is not good, and it is easy to defo...
