Description

一种油泥无害化、资源化集成处理方法和系统 技术领域
本发明属于危险废弃物处理技术领域、具体涉及一种油泥无害化化、资源化集成处理方法和系统。
背景技术
我国石油开采和炼制行业每年产生的油泥达数百万吨,而且每年还在快速增长,含油污泥被列为《国家危险废物名录》(2016环保部令第39号)H08类危险废弃物,原因就是该类油泥含有各种致畸、致癌的有毒物质”,如苯系物、酚、蔥、能类等。含油污泥减量化、无害化、资源化处理已迫在眉睫,在这方面国内的技术研究较少,国外技术成功引进的案例更少。
含油污泥种类繁多、性质复杂,相应的处理技术和设备也呈现多元化趋势,目前含油污泥处理技术有调质-机械脱水工艺、热处理工艺(化学热洗、焚烧、热解吸)、生物处理法(地耕法、堆肥法、生物反应器)、溶剂萃取技术以及对含油污泥的综合利用等。国外目前如加拿大MG工程公司采用的是机械脱水工艺配自己专有的药剂,荷兰吉福斯公司采用的是调质-机械脱水+生物处理法,德国HILLER公司采用的是调质-机械脱水;新加坡的CLEANSEAS公司则采用机械脱水+美国ADTU热解吸的工艺,实验室研究表明溶剂萃取也能达到污泥处理要求,但是溶剂萃取目前只局限于实验室研究,很难达到工业化应用。因此,国外现阶段应用较多并且比较成功的是采用物理法、化学法(离心分离加化学药剂处理)相结合,即调质-机械脱水工艺,该技术比较成熟,在欧美各地的油田应用广泛并且处理效果好。该方法的不足是处理效果会受污泥来源的影响,对于污泥中含有大量的砖瓦、草根、塑料等杂物需要配套预处理设备和工艺。
目前国内油田采用的油泥处理主流工艺为热解法、焚烧法和热洗处理含油污泥。热洗处理含油污泥仅能简单做到资源化,对原料适应性差,污染物排放不达标;焚烧法虽然有最大程度的减量化、无害化,对原料适应性强的优点,但是也存在能耗高,设备投资高,工艺技术要求高的缺点,并且污泥中的原油得不到回收,产生了资源浪费。热解法在500℃-600℃间接热解虽然能够大部分回收原油,但是处理后污泥中含油量仍然较高,达不到国家现行排放标准要求,同时高温气相生成的二恶英随不凝气体排放达不到最新排放标准要求。
根据《危险废物处置工程技术导则》(HJ 2042-2014)“易燃性废物宜优先选择焚烧处置技术,并应根据焚烧条件选择预处理方式”;《危险废物焚烧污染控制标准》(二次征求意见稿代替GB18484—2001)其排渣热灼减率和烟气排放标准较GB18484—2001标准有了提高,虽未正式发布实施,但于行业已起到倒逼技术升级的作用。
技术问题
有鉴于此,本发明的目的是提供一种油泥无害化、资源化集成处理方法和系统,以便降低油泥处理成本,实现油泥的无害化、资源化和集成化处理。
技术解决方案
本发明通过以下技术手段解决上述问题。
一种油泥无害化、资源化集成处理方法,包括如下步骤。
S1:将待处理油泥分类贮存。
S2:将贮存的待处理油泥混配后进行破碎,一边破碎,一边进行热水淋洗。
S3:将经过热水淋洗、破碎后的油泥进行初次机械挤压分离,初次分离出的泥渣在挤压脱水后返回步骤S1暂存,初次机械挤压分离出的含泥油水加热并加入药剂、搅拌,然后再次进行离心分离,离心分离出的水用于步骤S2中的热水淋洗,离心分离出的油进贮油罐暂存,离心分离出的油泥返回步骤S1与初次机械挤压分离出的泥渣同区域暂存。
S4:将两次分离出的泥渣进行造粒干化,造粒干化后油泥颗粒进行热解焚烧处理;干化过程中因油泥蒸发产生的蒸汽冷凝成水后,用于步骤S2中的热水淋洗;干化过程中产生的废气作为热解焚烧处理的助燃空气。
S5:将热解焚烧处理产生的余热经余热锅炉回收利用,余热锅炉产生的蒸汽一部分用于蒸汽发电、一部分用于步骤S2中的喷淋热水加热升温、一部分用于步骤S4中的造粒干化加热,造粒干化采用间接换热,蒸汽凝结水回余热锅炉循环利用。
进一步,步骤S4中,热解温度为700~850℃,在还原性气氛下进行热解,还原性气氛控制过剩空气系数在0.5~0.75,热解产生的排渣经冷却后外运综合利用,热解产生的可燃气随烟气进二燃室二次燃烧,二次燃烧升温至1100~1200℃,在此温度下烟气停留时间≥2s,二次燃烧过剩空气系数控制在1.4~1.5,二次燃烧的烟气余热经余热锅炉回收利用。
进一步,步骤S2中,热水淋洗的水温在80~90℃,喷淋热水与油泥的质量比例为1:1~2:1。
进一步,步骤S3中,再次离心分离时,含泥油水的温度加热至85~95℃。
