Description

母子导向浮阀
发明领域本发明涉及浮阀塔核心部件——浮阀。
背景技术
本发明人发明了导向浮阀塔板并于2002年申请了中国专利(专利号CN02112748.4)。该浮阀塔板与F1型浮阀塔板相比,阀片不易脱落和卡死,压降明显降低,能耗下降,处理量提高,分离效果提高。但在实践中发明人发现,该导向浮阀塔板的操作弹性还不够大,当气体流量较大时,该导向浮阀塔板能充分发挥其优越性,但当气体流量较小时,由于不能把所有的浮阀阀盖都打开,所以效果就不是很好。我国炼油装置处理能力受原油来源的影响变化幅度较大,因此需要分馏塔在较大气体负荷变化范围内能保持较高的分离效率。
发明内容
本发明是本发明人设计的导向浮阀(中国专利CN02112748.4)的一种改进。本发明的目的在于提供一种操作弹性大、效率高、压降小的母子导向浮阀。
本发明的技术方案如下:一种母子导向浮阀,母阀的阀盖为一个以长对角线为对称的四边形,长边的夹角指向溢流堰,母阀阀盖下至少有两个阀腿,前端阀腿长于后端阀腿,使母阀全开时,母阀的阀盖与阀孔板之间向着溢流堰张开一个2-10°的夹角,母阀阀盖上有一个母阀阀孔,母阀阀孔上有子阀,子阀为活动阀,子阀也为四边形,其四条边与母阀的四条边平行,子阀阀盖下至少有两个阀腿,子阀前端阀腿等于或长于子阀后端阀腿,使子阀全开时,子阀阀盖与母阀阀盖之间向着溢流堰张开一个0-10°的夹角。
上述的母子导向浮阀,母阀阀盖和子阀阀盖的四边形顶角为圆弧形,使母阀阀盖和子阀阀盖沿液流方向呈流线型。
上述的母子导向浮阀,子阀阀盖面积为母阀阀盖面积的30~60%。
上述的母子导向浮阀,在子阀后面的母阀阀盖上开有导向孔,导向孔上有导向板,导向板的导向与液流流向一致,从该导向孔喷出的向前气流,可以部分抵消从子阀缝隙喷出的向后气流,对液流产生更大的向前推动力,更好地降低液面梯度。
本发明所述的母子导向浮阀可以用各种金属材料制成,必要时亦可以用金属材料与非金属材料复合制成,以满足不同工况场合的需要。
本发明的母子导向浮阀具有如下优点:(1)当气速较小时,母阀静止在塔板上,子阀升起,此时的气液传质主要由子阀起作用;随气相负荷增加,子阀全开启,母阀亦受到足够多的压力提升而逐渐开启,进入工作状态。此时,上升气相分别从母、子阀片升起的环隙间进入液层。这样可以有效和较大范围地调节塔板开孔率和阀孔气速,因而具有较大的操作弹性。而且在低气速下仍保持高效率,且随着通量的增加,效率保持基本不变。
(2)母子导向浮阀提供了极大的气流通道以及气相和液相的接触面积,使得塔板的处理量和效率都大幅度提高。
(3)子浮阀为根据母阀形状特别设计的对称四边形,其折线侧边与母浮阀的折线侧边保持平行,这样能够均匀分割母浮阀上部的传质空间,使气体分散更加细密、均匀,气液接触充分。
(4)母、子浮阀都为对称四边形,对液流具有良好的导向作用,推动液体前进,从而有效消除液面梯度,减小液体的返混程度。
(5)在子阀后面的母阀阀盖上设有导向孔,从该导向孔喷出的向前气流,可以部分抵消从子阀缝隙喷出的向后气流,对液流产生更大的向前推动力。
(6)母子浮阀前端阀腿长于后端阀腿,使得阀盖全开时,阀盖与阀孔板水平面之间呈锐角,于是相对液流方向而言,与之同方向气流量将大于逆向气流量,整体效果是推动液体向前运动,有效消除了板上液面梯度。

图中:A——母阀                B——子阀A-1——母阀前阀腿        B-1——子阀前阀腿
A-2——母阀后阀腿        B-2——子阀后阀腿A-3——母阀阀脚          B-3——子阀阀脚A-4——母阀起始定距片    A-5——母阀阀孔A-6——导向孔具体实施方式以下通过实施例进一步说明本发明。
实施例一:乙醇-水精馏塔Φ1200mm,共有36层塔板,开孔率11.5%,原塔板全部为F1型浮阀。将全部塔板改为本发明的母子导向浮阀塔板。母阀阀盖长100毫米,前端长65mm,后端长35mm,最大宽度45mm,阀盖上导向孔A-6为舌形,高2毫米。前阀腿A-1,宽为8毫米,长为16毫米,后阀腿A-2,宽为12毫米长为13毫米。子阀为对称四边形浮阀,阀片的长度40mm,前端长45mm,后端长15mm,最大宽度为20mm。前阀腿,宽度为5mm,长度为7mm;后阀腿宽度为5mm,长度为6mm。改造中保留了原塔板固定件,只更换了塔板。改造后在处理量34.7t/d及70.0t/d情况下进行了生产标定。从标定结果得出,使用本发明的母子导向浮阀后,乙醇纯度由94.1%提高至94.9%。产品质量进一步改善,说明母子导向浮阀的板效率比F1型浮阀高。从生产实践看,处理量在30t/d~90t/d均能平稳操作,产品质量合格,达到了技术改造的目的。说明本发明的母子导向浮阀不但生产能力提高,而且操作弹性也增大。
实施例二:乙酸-水精馏系统,原为普通筛板塔盘。设备投入运行后一直不正常,主要表现在生产负荷偏低,只能达到原设计负荷的90%(原设计最大处理量为250t/d),而且工况和负荷稍有波动立即出现雾沫夹带,经过多次观察、调整,反复计算后认为是因为气体穿孔速度过大,导致塔板效率降低。为提高这套设备的生产能力,采用本发明专利。原精馏塔Φ1600mm,共有88层塔板,开孔率12%。将全部塔板改为本发明的母子导向浮阀塔板。母阀阀盖长120毫米,前端长75mm,后端长45mm,最大宽度50mm,阀盖上导向孔A-6为舌形,高3毫米。前阀腿A-1,宽为8毫米,长为16毫米,后阀腿A-2,宽为12毫米长为13毫米。子阀阀盖的长度80mm,前端长55mm,后端长25mm,最大宽度为20mm。前阀腿,宽度为5mm,长度为7mm;后阀腿宽度为5mm,长度为6mm。。投入运行后,塔板最大负荷360t/d,最小负荷100t/d,生产负荷大幅度波动时仍能平稳运行。
