大豆浸出制油工艺安全风险与事故隐患分析Analysis of safety risks and hidden dangers regarding to soybean leaching technology

Abstract

为有效管控大豆浸出制油工艺的安全风险，消除事故隐患，预防安全事故，对大豆浸出制油工艺安全进行了辨识，对其工艺安全风险进行了评价，同时，梳理了安全风险与事故隐患的关系，并提出了工艺安全生产风险管控措施。大豆浸出制油工艺的安全生产风险较高，主要事故风险为坍塌、火灾、粉尘爆炸，主要风险点的风险等级为较大风险或重大风险。生产企业可通过建立并落实安全生产风险分级管控和生产安全事故排查治理双重预防工作机制，管控工艺安全生产风险，降低安全生产风险等级，减少隐患存量，确保生产装置和作业场所具备安全生产条件，同时可设置大豆粉尘抑爆系统，高温蒸汽泄漏紧急自动切断系统，正己烷、混合油泄漏紧急自动切断系统，提升工艺本质安全系数。In order to effectively control the safety risks during soybean leaching process, eliminate the hidden dangers and prevent safety accidents, the safety of soybean leaching technology was identified, its process safety risk was evaluated, the relationship between the safety production risks and the hidden dangers was sorted out, and control measures of the safety production were put forward. The safety production risk of the soybean leaching process is high. The main accident risks are collapse, fire and dust explosion, and the risk levels of the main risk points are greater risk or major risk. By establishing and implementing a dual prevention mechanism for the grading and control of production safety risks and the investigation and management of production safety accidents, production enterprises can control production safety risks, reduce the level of production safety risks, reduce the stock of hidden hazards, to ensure that production units and workplaces are equipped with safe production conditions. Meanwhile, enterprises can enhance the essential safety coefficient of the process by setting up soybean dust explosion suppression systems, automatic cut-off system of high temperature steam leakage emergency, automatic cut-off system of n-hexane and miscella oil leakage emergency.
