The invention discloses a three-dimensional risk-based large-scale coal gasification device space security layout method, which includes establishing a three-dimensional risk assessment model for a large-scale coal gasification device; establishing an objective function for the multi-series mirror image layout of a large-scale coal gasification device; establishing a multi-series large-scale coal gasification device Constraints of the mirror layout; the model is solved using the DICOPT solver in the GAMS software. The present invention evaluates the damage index of the target equipment as the consequence of the accident, quantifies the influencing factors of the damage index of the target equipment by using the fuzzy comprehensive evaluation method, and analyzes the characteristics of the process flow of the large-scale coal gasification device, and proposes a new The mixed integer nonlinear programming model and some additional constraints are added to effectively improve the solution efficiency of the model. At the same time, this method provides a solution idea and method theoretical support for the risk reduction and selection of effective safety protection measures in the production and operation stage of large-scale coal gasification units.
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...
