The Risk Analysis And Evaluation Of Corn Cob Xylose Production Enterprises

As an important chemical raw material,xylose,possessed safety loophole such as fire,explosion,corrosion and fall during its production process.Carrying out risk analysis of corn cob xylose production enterprises had practical application for maintenance enterprise production safety and protect the personal safety.This article through the analysis of the dangerous and harmful factors of xylose production enterprises,build security evaluation index model and proceed analytic hierarchy process for the comprehensive assessment.Modular the production process from the xylose production technology,and classify the safety loophole of the Production units,production materials,production equipment and production environment.Getting the dangerous and harmful factors during the Xylose production process was Fire explosion,electric shock,mechanical damage,falling,burning hot,lifting injuries,acid and alkali corrosion and noise.Electric hoist crane falling accident analyzed by accident tree analysis method,we get the main reasons was security check before operation,work safety supervision,and personnel operation,equipment reliability and influence factors such as ambient conditions.Xylose hydrolysis section analyzed by HAZOP,the main production safety accident reasons was equipment corrosion,personnel error,devices,equipment,and failure problems.What's more,it is dangerous for the use of chemicals.High pressure steam which was the energy source analyzed by TNT equivalent weight method,the Explosion hazard radius and abstract the important dangerous and harmful factors.By using three different kinds of analysis method of xylose production process was found a gist for extension comprehensive evaluation index.The security of xylose production process of Xin Pu xylose co.,LTD in Changzhi ShanXi province was evaluated by extenics.Through the establishment 4 first-level indicators,18 secondary indexes,using extension analytic hierarchy process method establishment the extension matrix,introducing the concept of extension interval number to separate thejudgment matrix,make the evaluation more approach the practical situation;Introducing matter-element's extension theory to structure evaluate the matter-element,classical and extensional matter elements,using extension dependent function,calculate the index extension of correlation degree and the degree of safety evaluation come close to a certain level,safety assessment conclusion is safety A come close to B.Using the system has the following advantages,such as simplifying the evaluation process,friendly software interface,simple operation,easy to learn.Using the system provides a fast way for xylose enterprises improving safe production condition.
