Abstract
本实用新型提供了一种油泥砂减量化处理装置，前期筛选分离后的油泥砂进入均质撬的搅拌罐中，通过加热、加药和加水搅拌处理，搅拌后的均质通过提升泵提升至两相撬的两相离心装置中，进行固液分离，分离后的固相进入泥砂池进入无害化处理，分离后的液相进入缓冲罐，然后通过提升泵将缓冲罐中的液相输送到三相撬中的三相离心装置，实现固、油、水三相分离，其中固相进入泥砂池进行无害化处理，油进入缓冲油罐可直接使用，水进入污水罐后进入污水处理系统处理。该实用新型通过加热、加药均相气浮和高速离心等方法，改变了油、砂、水的分布状态，解决了油与泥砂分离的问题，且处理效果好，无二次污染，回收了石油，为油田油泥砂处理提供了支持。
Description
技术领域
本实用新型属于石油、化工机械装置领域，主要用于油田、石化行业的油泥砂处理，特别是一种油泥砂减量化处理装置。
背景技术
在石油勘探、开采、炼制、储运过程中，由于自然沉降等原因导致大量原油或油品与土壤、水或其他杂质混合形成油泥砂。油泥砂通常分为：落地油泥砂、罐底油泥砂、炼油厂油泥砂等，属于国家严格管控的危险废弃物。
油泥砂主要有以下几个特征：水量高、体积大；成分复杂、处理难度大；含有大量的污油和可燃物质；有害成分多数超过排放标准。
现今国内外处理含油污泥的方法一般有焚烧法、生物处理法、热洗涤法、溶剂萃取法、化学破乳法、固液分离法等，但都因针对性不强，处理成本高等缺点没有推广，对含油污泥进行减量化、资源化以及无害化等综合处理，成为国内外环境保护和石油工业的重点之一。
中国专利授权公告号CN207862145U公开了一种含油污泥处理系统，工艺含油污泥成套处理设备采用“破碎筛分+复合搅拌分油+泥砂分离处理+泥水分离处理+油水分离处理”的连续处理工艺可使处理后的泥砂达到铺路或垫井场等再利用要求，油水分离后的油可回收，废水达到GB31570-2015《石油炼制工业污染物排放标准》的排放要求，工艺配套设备采用模块化设计，结构紧凑，占地面积少，便于处理产能调整；自动化控制程度适中，劳动强度低，操作简单，运行管理方便。此装置虽然可以达到排放标准，但是污水或污油中仍含有少量泥砂。
中国专利公开号CN108439752A公开了一种泥砂分离脱水一体化油泥砂减量设备，其中所述的储存池通过泵及管线连接旋流分离器的放液口，旋流分离器顶部开有加药口，与药剂罐连接，旋流分离器中部的出泥口连接储泥池，底部的出砂口连接储砂池，储泥池与振动筛连接，振动筛的液相出口连接脱光机，固相出口连接储砂池，脱水机的固相出口与储砂池连接，液相出口回流至储存池；振动筛及脱水机固定于传送带上，传送带固定于储泥池上方；优点为：对污泥粒径进行了有效的分离，将粒径控制在小粒径范围内，可有效提高回注效率，降低回注成本。但是储砂池中的泥砂仍含有石油，需要进一步处理。

图2为本实用新型实施例二的油泥砂减量化处理装置工艺流程简图。
具体实施方式
下面结合附图对一种油泥砂减量化处理装置装置的技术方案做进一步的详细说明。
实施例一
如图1所示的一种油泥砂减量化处理装置，包括控制撬、均质撬、两相撬、三相撬、污水处理系统13；控制撬包括主控制柜及分别设置在均质撬、两相撬、三相撬的分控制柜，主控制柜通过PLC程序控制分控制柜；均质撬包括2个搅拌罐6以及设置在搅拌罐6上的加药系统、加水系统、加热装置，搅拌罐6底部设置出料口，搅拌罐6的加热系统通过在搅拌罐6内部设置蒸汽盘管，通入蒸汽进行加热；搅拌罐6内部设置热电偶，热电偶与控制撬的PLC控制系统电性连接；两相撬包括两相离心装置7、缓冲罐8及清水罐12，两相离心装置7 为固液两相离心机，两相离心装置7进口与搅拌罐6的出料口通过设置有出料泵的管道连接，两相离心装置7的液相出口与缓冲罐8进口通过管道连通；清水罐12与搅拌罐6的加水系统连通；三相撬4包括三相离心装置9、污水罐10、缓冲油罐11，三相离心装置9为液液固离心机，三相离心装置9的液相出口分别与其对应的污水罐10、缓冲油罐11进口连通；两相离心装置7、三相离心装置9的固相出口的泥砂进入泥砂池5；污水罐10的污水进入污水处理系统13，两相离心装置7位于缓冲罐8及清水罐12罐体顶部，三相离心装置9位于污水罐10、缓冲油罐11罐体顶部；清水罐12引出管线连通两相离心装置7及三相离心装置9。油泥砂减量化处理装置设置有保温措施，对管线及各个罐体采用硅酸盐保温材料进行整体保温。
前期筛选分离后的油泥砂进入均质撬的搅拌罐中，通过加热、加药和加水搅拌处理，搅拌后的均质通过提升泵提升至两相撬的两相离心装置中，进行固液分离，分离后的固相进入泥砂池进入无害化处理，分离后的液相进入缓冲罐，然后通过提升泵将缓冲罐中的液相输送到三相撬中的三相离心装置，实现固、油、水三相分离，其中固相进入泥砂池进行无害化处理，油进入缓冲油罐可直接使用，水进入污水罐后进入污水处理系统处理。
实施例二
如图2所示，实施例一与实施例二基本相同，不同之处在于搅拌罐6顶部设置管道与缓冲油罐11连通，可以通过均相气浮的方式将搅拌罐6中上层浮油传送到缓冲油罐11中；污水罐10底部设置带有提升泵的管道与搅拌罐6顶部连通，可以将污水输送到搅拌罐中实现污水循环使用，达到节药用水的目的，当污水达到循环次数后再传送到污水处理系统中。
通过以上两种实施方式，针对搅拌罐内不同分层油泥砂的特性，通过药剂筛选，工艺参数的调整，油泥砂减量化处理后，可以实现泥砂含有控制在3％以内，泥砂含水控制在75％以下，减量华率在80％以上，达到设计指标，可以满足设计要求。
最后说明的是，以上实施例仅用以说明本实用新型的技术方案而非限制，本领域普通技术人员对本实用新型的技术方案所做的其他修改或者等同替换，只要不脱离本实用新型技术方案的精神和范围，均应涵盖在本实用新型的权利要求范围当中。
