5 minutes to understand the safety measures and guarantee of coal chemical equipment overhaul

In the 1960 s, coal chemical industry in our country gradually entered a stage of rapid development, at this stage not only expand the production scale, it also introduces many advanced production technology, laid a solid foundation for our country to realize industrial modernization development of modern coal chemical industry is facing the new situation and new challenge, but with the development of industry a clear positioning, as well as the national energy security and clean utilization of coal demand, coal chemical industry in our country the overall technology level and industrial scale will continue to lead the world in order to further explore the safety measures and guarantee of coal chemical industry equipment maintenance strategy, the importance of work is introduced as follows

1.1 achieve good economic benefits for the enterprise itself, good economic benefit is not only the pursuit of goals, it is the basis for the enterprise to survive in the process of coal chemical industry of daily production, if equipment maintenance less will lead to work efficiency to reduce or even equipment damage, such not only need to spend a lot of the maintenance cost, also can cause plant shutdown, which affect the enterprise's comprehensive economic benefit, therefore, do a good job in coal chemical equipment repair can effectively ensure the enterprise's economic benefit is 

1.2 promote the stable development of the industry

Feature determines the development of coal chemical industry characteristics, in the process of coal chemical industry of daily production need to use a large amount of high temperature and high pressure equipment, many devices need to face the corrosive strong working environment, equipment maintenance and repair work to eliminate all kinds of potential safety hazard in embryonic, thus achieve the stable and healthy development of the industry, 

1.3 the objective requirement of the national production safety policy

From the perspective of national safety, the state has put forward various safety production technologies and standardized standards for coal chemical industry production at present. Only those enterprises that meet the national standards are qualified for production, while those that fail to meet the standards must be eliminated by the market and the society

2.1 检修前的保障措施 　　

在煤化工设备检修过程中，煤炭原材料本身的特殊性决定了煤化工的工艺危险性。许多的工艺生产过程中设备都需要面对高温、高压的环境，而且整个原材料从原煤运输、破碎、筛选、研磨、输送等均需要经过复杂的工艺环节，每个环节都需要及时处置“生病设备”，如果仅仅依靠设备出现故障后再进行维修，不但会导致生产停滞，更会带来安全责任与风险。 　　前期的保障工作中，首先需要编制好专项和综合紧急停车方案与培训演练，这样一来在突发状况停车时就可以及时做出反应，并根据停车的工艺环节进行分析，从容应对；其次，设备的隔离要提前做好隔离方案，由于反应过程中的高压危险性设备较多，检修前要做好泄压、置换、隔离等处理措施，确保检修安全；再次，工业三废的清理也要提前做好准备，煤化工的生产中都会留下大量的固体残渣，这些残渣不但处理难度高，而且普遍具有毒害危险，需要做好工业固废的妥善处置。 

2.2 检修过程中的保障措施 　　

在检修的过程中可能需要涉及多个工艺系统，需要可靠的隔离措施进行隔离。比如说气化装置在停车检修时，需要提前对装置相连火炬系统进行隔离，隔离盲板导盲后，盲板挂牌上锁，上述的工作全部完成后再进行系统的检修。除此之外，在对非常用设备进行检修时，采用开放式隔离方法，能有效避免危险物料泄漏而带来的人员伤亡。煤气化装置均涉及一氧化碳、硫化氢等有毒有害气体，除了检修前需要惰性气体置换，检修过程中受限空间的气体检测需要连续检测并且每两小时记录一次，避免作业工况发生改变而产生安全风险。压力容器、压力管道等特种设备检修需要安排有资质的专业检修队伍。 　　检修过程中，操作人员作为主要检修作业监护人，需要具有强烈的责任心、丰富的作业经验、专业的监护技能，执行公司实行的安全作业规范，主动发现并解决人的不安全行为和物的不安全状态，消灭隐患、保证检修作业安全。 

2.3 检修后的保障措施 　　

检修后的保障工作主要涉及到工艺本身以及反馈。煤化工检修特点：检修设备多、检修项目多；完成设备检修工作后，需要及时进行验收处理，通过验收来确保检修质量，检修质量影响着装置技术升级、工艺优化以及产品调整等方方面面。验收完成后，检修人员还可以参与装置检修后试车，这样可以及时发现检修过程中出现的问题并进行排除。建立岗位责任制，检修人员需要承担起相应的验收职责，开车后如果设备出现问题或者故障，需要承担相应的责任。除此之外，为了确保检修的效率，还可以借助于自动化的检测技术，通过建立模型模拟运行工况、检测技改效果，模拟通过后进行技术交底与实际操作，可以有效提升工作效率。 

综上所述，设备检修对于企业发展具有重要意义，通过煤化工设备检修技术优化及安全保障管理，可以显著降低设备的故障率，提高生产效率的同时降低安全风险，对企业的可持续发展具有促进作用。结合目前企业的设备检修现状来看，除了要做好检修前期、中期的安全保障管理工作，也需要完善煤化工设备检修后的运行反馈，这样才能够最大程度的提升检修质量，增加安全保障级别。为实现煤化工装置的“安、稳、长、满、优”运行提供坚实壁垒，为公司安全、高效生产保驾护航。
