Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] Such as figure 1 Shown, the present invention comprises the following steps:

[0036] Step 1. Determine that the analysis object is "explosion of carbonylation production of acetic anhydride synthesis reactor";

[0037] Step 2. Build the accident tree.

[0038] When compiling the fault tree, first analyze the top event to determine the direct, necessary and sufficient causes of the top event, and it should be noted that it is not the basic cause of the top event. Take this direct, necessary and sufficient cause event as the next top event (i.e. intermediate event), and then determine their direct, necessary and sufficient cause, and unfold it step by step. Analyze the cause and process of the top event, find out the direct cause of the top event, that is, the intermediate event, as the input events of the logic gate, connect them with appropriate logic gates accor...

Abstract

The invention relates to a carbonylation acetic anhydride production synthetic reaction kettle explosion analyzing method based on fuzzy fault tree. According to the explosion analyzing method, a fault tress is firstly constructed for the explosion accident of the carbonylation acetic anhydride production synthetic reaction kettle, with the application of the fuzzy fault tree theory, fuzzy reliability analysis is performed on the carbonylation acetic anhydride production synthetic reaction kettle according to the fuzzy information obtained through statistics of the actual operating state of onsite equipment and the expert experience, so that the possibility distribution of fuzzy probability of the explosion accident of the carbonylation acetic anhydride production synthetic reaction kettle is worked out; and structural importance analysis is carried out on the possibility distribution by the structure importance coefficient approximate value method, the weighted structural importance analyzing method which sorts and grades the bottom events of the fault tree is utilized to determine the most principal factor which affects the system, so the invention provides a new method and a new approach for the safety analysis of the system.

Description

technical field [0001] The invention belongs to the fields of chemical safety, environmental system safety and control theory and control engineering, and relates to an explosion accident analysis method of a carbonylation production acetic anhydride synthesis reactor based on a fuzzy fault tree. Background technique [0002] In the production of chemical enterprises, most of the production materials are flammable, explosive, toxic, and corrosive. At the same time, the chemical production process is characterized by strong continuity and complex technology. With the development of production technology and the expansion of production scale, chemical production safety has become a social issue. Once a fire or explosion accident occurs, it will not only lead to production stoppage and equipment damage, but also cause a large number of personal casualties, and even spread to the society, resulting in incalculable losses and irreparable impacts. Therefore, it is necessary to co...
