Abstract

一种防止油罐油品蒸发的箱式组装内浮顶,其特征罐体内设由若干个长方形密封箱体横与纵向交替排列的内浮顶,每个密封箱体之间设置盖板及底部连接板,箱体四周压铸有凹凸加固点可增加支承力,本实用新型浮力大,密封性能好,同时减少消防用水量。

Description

箱式组装内浮顶
本实用新型涉及石油化工储油罐领域,具体说属于防止储油罐油品蒸发损耗而飘浮在油面上升降的浮动顶盖.
由于储油罐油品蒸发损耗,从节能和环保与安全等角度考虑,愈来愈被石油行业及有关部门所重视,因油品储存过程中的蒸发损失,不仅是造成重大的经济损失,而且污染环境,同对油品质量下降。目前国内外有多种浮顶来解决上述的缺陷,但效果均不理想,一种盘式内浮顶,有单盘或双盘都存在重量重、成本高、现场焊接及施工的周期较长。另一种铝合金内浮顶,是采用铝皮制成圆型管子作浮筒,在浮筒上设型铝材,型部件上复盖铝皮,因此浮筒与盖板距离大,有一定的油气空间,消防水用量大。再一种用泡沫块作浮子,虽然重量轻,但自身的封闭性能差,静电导出不佳。
本实用新型的目的是提供重轻、消除油气空间,减少消防用水量,以及密封性能好的一种箱式组装内浮顶。
为完成上述目的所采取的技术方案:根据原有的油罐体内设置内浮顶并与密封件相互配合,此内浮顶由若干个长方形密封箱体纵横交替排列,每个密封箱之间设置盖板,而密封箱本的底部设下连接板,同时在密封箱体的四周压铸凹凸形加固点。
本实用新型由密封箱体通过盖板和下连接板组成浮顶,既增加浮力,而且密封箱体又成为内浮顶骨架,减轻浮顶的重量,密封箱体的四周设有凹凸形加固点,增加密封箱体的支承强度,同时减少消防用水量。
本实用新型实施例结合附图加以详细描述。
图1为本油罐整体结构图;
图2为内浮顶结构图;
图3为内浮顶整体组合结构图。
根据图1所示,现有油罐的底端两侧分别设置进口扩散管1和油罐入孔12,中间设密封件4及上、下圈板3和11,整个油罐内两端设防旋转装置5和9,使内浮顶18不会转动,油罐同时设置罐顶量油孔7和罐顶入孔,油罐中间设内浮顶18,内浮顶18与密封件4配合,上述内浮顶18由若干个长方形密封箱体14横与纵向交替排列如图3所示,内浮顶18下端设支腿2,并且设排液阀10和入孔通气孔13,每个密封箱体14之间设置盖板15如图2所示,密封箱体14的底部设下连接板17,为了加强密封箱体14的支承度、在四周压铸凹凸形加固点19,而且加强密封性能在密封箱体14用薄不锈钢皮板连接处用δ1耐油橡胶条16以及螺丝进行密封。
