Description

Intelligent evaluation system and evaluation method for fire emergency drilling in chemical tank farm Technical Field The invention relates to the technical field of emergency drilling evaluation, in particular to an intelligent evaluation system and an evaluation method for fire emergency drilling in a chemical tank farm. Background The chemical tank farm is used as the core area of high-risk industry, stores a great amount of inflammable, explosive, toxic and harmful chemical raw materials, and is of great importance in safety management. In order to cope with possible fire accidents, the regular development of fire emergency exercises is a necessary means for checking the feasibility of emergency plans and improving the actual combat ability of firefighters. Currently, in the field of safety evaluation of chemical tank areas, the prior art focuses on static risk evaluation index system construction and calculation of theoretical models. For example, chinese patent CN104657810a discloses a fire explosion risk assessment method in petrochemical dock storage tank area, which uses a hierarchical analysis method to calculate risk weights by establishing a multi-dimensional risk assessment index system including dangerous goods, operation safety, personnel, environment, management and the like, and combines a pool fire hazard model (including a combustion rate, a flame height and a heat radiation flux formula) to determine theoretical risk values of assumed accidents, thereby classifying acceptable risk levels. Although the technology provides a quantitative risk grading basis for the safety management of the storage tank area in a theoretical level, and is beneficial to preventing accidents, the technology mainly focuses on risk prediction and grading before the accidents, and real-time monitoring and evaluation of the scene situation of transient and changeable in the drilling process are difficult. In an actual fire emergency drilling link, the traditional evaluation mode still mainly depends on manual field observation and subjective judgment. Drill evaluators typically stand in a safe area and score fire tactical, team coordination by eye and experience. However, the traditional method has the obvious technical limitations that firstly, the environment of a fire exercise site is complex, a large amount of dense smoke, flame radiation and water mist are accompanied, the manual sight is extremely easy to block, the abnormal temperature distribution around a storage tank, the fine change of flame morphology and the real-time fluctuation of wind direction and wind speed are difficult to penetrate through the smoke to accurately capture, secondly, for key tactical indexes of fire extinguishment and rescue, such as whether the thickness and area of foam coverage reach standards, the arrangement angle and distance of a water gun array are in an optimal efficiency range, the manual evaluation is difficult to provide accurate quantitative data support, so that the evaluation result is high in subjectivity and low in accuracy, and finally, the manual recording and post analysis are time-consuming and labor-consuming, the evaluation report generation period is long, and the requirements of quick disc multiplexing and timely correction of an emergency plan cannot be met.
