Large-scale coal gasification device space safety layout method based on three-dimensional risks

Abstract

The invention discloses a large-scale coal gasification device space safety layout method based on three-dimensional risks. The method comprises the steps that a large-scale coal gasification device three-dimensional risk assessment model is established; an objective function of multi-series mirror image layout of the large coal gasification device is established; constraint conditions of multi-series mirror image layout of the large coal gasification device are established; and a DICOPT solver in GAMS software is adopted to solve the model. According to the method, the damage degree index ofthe target equipment is used as an accident consequence for evaluation, influence factors of the damage degree index of the target equipment are quantified by adopting a fuzzy comprehensive evaluationmethod, and a new mixed integer nonlinear programming model is provided by analyzing process flow characteristics of the large-scale coal gasification device; and some additional constraint conditions are added, so that the solving efficiency of the model is effectively improved. The method provides solution thinking and method theoretical support for risk reduction of the large coal gasificationdevice in the production operation stage and selection of effective safety protection measures at the same time.

Description

technical field [0001] The invention belongs to the technical field of optimal layout of chemical process equipment, and in particular relates to a three-dimensional risk-based space safety layout method for large-scale coal gasification equipment. Background technique [0002] The large-scale coal gasification plant contains key dangerous equipment such as gasifiers, and the internal layout of key dangerous equipment such as gasifiers is compact. Once an accident occurs in a certain equipment, it is easy to affect the adjacent equipment, causing a chain of accidents, and the gasification Furnaces and other key dangerous equipment contain high-temperature, high-pressure, toxic, flammable and explosive corrosive mixed gases, which greatly increases the possibility of domino accidents and seriously threatens the safety of people's lives and property. [0003] Therefore, there is an urgent need to establish a comprehensive method for the spatial safety layout of large-scale coa...
