Интегрированная система управления безопасностью производств, связанных с обращением горючей пыли

Abstract

Purpose. For chemical, food, woodworking, pharmaceutical and some other industries, the main fire hazard factor is the circulation of explosive dust and gas flows containing combustible dust. For their disposal and removal from the volumes of equipment and premises, production aspiration systems (PAS) are used, their effective functioning is the key to production safety, so the given work is aimed at developing an automated PAS control system that ensures fire safety, as well integrating PAS control system into ACS of the production. To achieve this goal, the tasks of identifying the main hazards, developing an information environment for the system, developing mechanisms for the interaction of PAS accident triggers with the information environment and other subsystems of the automated control system, and, ultimately, creating the concept of a single system – an integrated production safety management system (IPSMS) are considered. Methods. The task is carried out by systematizing information related to the specifics of developing and operating industrial aspiration systems and evaluating information using logical functions, as well as developing the model based on the graph theory, namely, describing the system operation using Petri nets. Findings. To achieve the goal, the concept of an integrated production safety management system is proposed. The concept takes into account the peculiarities of the technological process and integrating with the subsystems of the production automated control system to neutralize both local accidents and accidents that develop into large-scale emergencies. The system considers the specifics of the main technological equipment and hardware solutions for dust collection in PAS, the degree of production automation, the categories of premises according to explosion and fire hazard. Based on the information analysis, a sequence of actions has been developed to eliminate the accident or minimize its consequences. To implement the tasks of IPSMS, a mathematical model based on the Petri net has been developed. Research application field. The results obtained can be used to design and improve automated systems for preventing accidents, fires and explosions in industries associated with the handling of combustible dust. Conclusions. The use of IPSMS will simplify the decisionmaking process linked with the analysis of a large amount of highly specific information related to the operation of industrial aspiration systems. The proposed methods and models are reliable tools\for the system of intelligent decision making support in stressful situations.
