Description
Technical Field
The invention relates to an application method of a virtual reality technology in an oil refining device, and belongs to the technical field of virtual reality devices.
Background
Most production devices of oil refineries have the characteristics of multiple process flows and complex equipment structures. Taking a normal pressure reduction device of an oil refinery as an example, the number of devices such as centrifugal pumps, heat exchangers and the like is nearly hundreds, and pipelines for connecting the devices are more numerous; also, the internal structure of large-scale equipment such as atmospheric towers and vacuum towers is very complicated, and particularly, the interior of tower equipment such as vacuum towers includes packing, reflux distributors, oil sumps, and the like. Due to the characteristics of the oil refining device, especially in the normal production process, when the process flow of the device is changed dynamically, especially during the startup and shutdown of the device, if an operator is not familiar with the process flow, the wrong process flow can be changed, and accidents of oil leakage and oil mixing can occur, and the accidents can occur repeatedly in the petrochemical industry, so that serious loss is brought to enterprises; meanwhile, when the device is in a production state and the running equipment has problems, if the internal structure of the equipment is not very familiar, the judgment is difficult to be made accurately in time, and the occurrence of accidents is slowed down.
At present, aiming at the characteristics of an oil refining production device, the device is operated safely and stably. One major task is to develop training and learning of operators, and as the operators of the production devices, it takes a long time for the operators to master all process flows and equipment structures of a set of production devices, and most of the operators still stay in theoretical books. For example, an operator can hardly accurately master the process of learning hundreds of process pipelines in the device, and the process is easy to leak if the operator does not work for a long time. Next, when an operator wants to learn knowledge about the structure of the equipment, he or she generally selects a viewing sheet or enters the inside of the equipment for viewing and learning during the maintenance of the equipment. The drawing is checked in a plan view, so that sometimes, the drawing cannot be known in detail and is not intuitive enough. Secondly, the running period of the device is long, namely 3 to 5 years, and long time is needed for deeply learning knowledge such as the internal structure of the equipment.
