Problems solved by technology

Because the calculation of the transportation cost of special-shaped modules is based on the maximum size of length, width and height, compared with regular-shaped modules, it will lose a lot of transportation volume, thereby increasing the transportation cost. prone to problems

Embodiment 1

[0041] 1) According to the equipment conditions, the steel frame components have three layers in total. The steel columns, steel beams and lateral supports of the steel frame components are initially selected. The steel beams are rigidly connected to the steel columns, and the steel beams are hinged to the steel beams. Each floor is paved with galvanized steel sheets;

[0042] 2) In order to ensure lateral stability, lateral supports are provided on both sides of each layer of the steel frame;

[0043] 3) In order to facilitate equipment installation and maintenance, each floor is equipped with safety guardrails and vertical ladders;

[0044] 4) Place complete sets of equipment, instruments and other equipment on the steel beams of each floor, and use bolts to connect the steel beams reliably;

[0045] 5) The finite element model of steel frame components is established by using Midas finite element software, and the connections between steel columns and steel beams, and stee...

Embodiment 2

[0049] 1) There are 4 lifting lugs on the top of the module, and the finite element model of the lifting lugs is established by using ANSYS finite element software;

[0050] 2) Calculate the total weight of the entire steel structure module, consider the three lifting points, and determine the load of each lifting point. The load combination value is taken according to the building structure load code, and the load increase factor in the hoisting process is considered at the same time, and it is calculated according to the static load;

[0051] 3) The boundary conditions of the finite element model are constrained at the circular hole and loaded on the left side;

[0052] 4) Calculate the strength of the lifting lugs during the "positive flip" process of the steel frame module from 90 degrees to 0 degrees at rest and the "reverse flip" process of the module from 0 degrees at rest to 90 degrees on site.

Abstract

The invention relates to a modular design method for a petrochemical device. The modular design method comprises the following steps: firstly, carrying out modular engineering design: dividing and encoding steel structure modules according to a process device area; then, three-dimensional modeling: establishing a basic model of the petrochemical device by adopting petrochemical device digital model software; and finally, assembling the modules, namely transporting, hoisting and assembling the modules of the petrochemical device on site. A traditional design method is replaced with modular design and development of green chemical product devices, the construction period is effectively shortened, the construction cost and the field risk are reduced, the construction safety level is improved,optimal utilization of resources is achieved, the quality is greatly improved, and the method is safer and more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of petrochemical engineering, in particular to a modular design method for a petrochemical device. Background technique [0002] The so-called module is to decompose the construction system into some standard units with independent structure and function, and then combine the standard units according to specific construction requirements. In the module construction factory, complete sets of equipment, skids, containers, pumps, pipelines, valves, instruments, electrical appliances, etc. are built and installed in the same structural frame, and the whole is transported to the site for installation. China's modular construction is now also developing in two directions. One direction is to make full use of site resources to develop into giant modules. The weight of a single module can reach several thousand tons or even tens of thousands of tons. This kind of huge module is limited by site and transportation. I...
