Description

催化裂化用非金属膨胀节
技术领域
本发明涉及一种膨胀节，更确切地说，是一种催化裂化用非金属膨胀节。
背景技术
催化裂化是石油二次加工的主要方法之一。在高温和催化剂的作用下使重质油发生裂化反应，转变为裂化气、汽油和柴油等的过程。主要反应有分解、异构化、氢转移、芳构化、缩合、生焦等。与热裂化相比，其轻质油产率高，汽油辛烷值高，柴油安定性较好，并副产富含烯烃的液化气。催化裂化用非金属膨胀节需要长期在高温高油环境下使用，一般的非金属膨胀节的软管耐高温耐腐蚀性较弱，用于催化裂化的环境下软管容易腐蚀，使用寿命较短。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种催化裂化用非金属膨胀节。
本发明的上述技术问题主要是通过下述技术方案得以解决的：
一种催化裂化用非金属膨胀节，包含一软管，软管的两端各连接一端管，端管的外壁各设有一限位圈，限位圈间连接多根限位螺杆，端管内各套接一延伸管，延伸管与端管间为螺纹连接，延伸管的末端各连接一法兰，所述软管的管壁为多层结构，包含位于中心的不锈钢丝网层，不锈钢丝网层的外侧设有PTFE塑料层，不锈钢丝网层的内侧设有耐油防腐层；
所述耐油防腐层的制备方法为：按重量份取 聚丙烯纤维5-8份，硫酸铝10-12份，乙酸乙酯25-28份，聚氨酯12-16份，羧甲基纤维素钠5-10份，氢氧化钡3-5份，纳米碳酸钙2-4份，烷基苯油4-8份，将所取原料加入搅拌机，在70-85℃的环境下搅拌25-35分钟制成混合浆料，将所得浆料均匀涂布在不锈钢丝网层内侧，自然固化后即可。
作为本发明较佳的实施例，所述的不锈钢丝网层的不锈钢丝的直径为0.2-0.5mm。
作为本发明较佳的实施例，所述的PTFE塑料层和耐油防腐层的厚度比为3：5。
本发明的催化裂化用非金属膨胀节的软管包含三层，中间的不锈钢丝网层可以使软管具有更大的强度和韧性，PTFE塑料层质地柔软不易皲裂，最内侧的耐油防腐层可以有效防止管道内油料对膨胀节的腐蚀，该耐油防腐层同样也耐高温，进而有效延长了膨胀节的使用寿命。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明的催化裂化用非金属膨胀节的结构示意图；
图2为软管管壁的层状结构示意图。
具体实施方式
下面结合附图对本发明的优选实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
如图1、图2所示，一种催化裂化用非金属膨胀节1，包含一软管10，软管10的两端各连接一端管41，端管41的外壁各设有一限位圈20，限位圈20间连接多根限位螺杆30，端管41内各套接一延伸管42，延伸管42与端管41间为螺纹连接，延伸管42的末端各连接一法兰50，所述软管10的管壁为多层结构，包含位于中心的不锈钢丝网层11，不锈钢丝网层11的外侧设有PTFE塑料层12，不锈钢丝网层11的内侧设有耐油防腐层13；
所述耐油防腐层13的制备方法为：按重量份取 聚丙烯纤维5-8份，硫酸铝10-12份，乙酸乙酯25-28份，聚氨酯12-16份，羧甲基纤维素钠5-10份，氢氧化钡3-5份，纳米碳酸钙2-4份，烷基苯油4-8份，将所取原料加入搅拌机，在70-85℃的环境下搅拌25-35分钟制成混合浆料，将所得浆料均匀涂布在不锈钢丝网层内侧，自然固化后即可。
作为对本发明更进一步的改进，所述的不锈钢丝网层11的不锈钢丝的直径为0.2-0.5mm。
作为对本发明更进一步的改进，所述的PTFE塑料层12和耐油防腐层13的厚度比为3：5。
该发明的催化裂化用非金属膨胀节的软管包含三层，中间的不锈钢丝网层可以使软管具有更大的强度和韧性，PTFE塑料层质地柔软不易皲裂，最内侧的耐油防腐层可以有效防止管道内油料对膨胀节的腐蚀，该耐油防腐层同样也耐高温，进而有效延长了膨胀节的使用寿命。
[对比实验]
取本发明5个非金属膨胀节和5个目前常用的非金属膨胀节进行对比实验。将10个膨胀节编号并同时接入实验管道，实验管道内通入催化裂化油液并循环流动，油液温度控制在120℃，油液循环时间为72小时。循环结束后冷却，将非金属膨胀节拆卸并进行对比测试，结果如下：
测试结果表明：本发明非金属膨胀节在高温高油的催化裂化环境下更加稳定，使用寿命更长。
以上仅仅以一个实施方式来说明本发明的设计思路，在系统允许的情况下，本发明可以扩展为同时外接更多的功能模块，从而最大限度扩展其功能。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
