目前在国内外新建炼厂的设计中,轻质油储罐广泛采用浮顶罐。为降低油罐蒸发损耗,若对现有固定顶罐进行改造,则涉及到生产运行及由此所造成的罐体变形、腐蚀、安全防护等一系列问题。因此,在短时间内要在全国范围把原有储存轻油的固定顶罐全部改造为浮顶罐或内浮顶罐是有一定困难的。而呼吸阀挡板则是一种制造简单、安装容易(不动火、不清罐)、不影响生产正常运行、投资少、收效快的节能降耗设备,适
Currently in the design of new refinery at home and abroad, light oil storage tanks widely used floating roof tank. In order to reduce the evaporation loss of the oil tank, if the existing fixed roof tank is to be reformed, it involves a series of problems of production operation and the deformation, corrosion and safety protection of the tank body caused thereby. Therefore, in a short period of time it is necessary to transform all existing fixed roof tanks storing light oil into floating roof tanks or floating roof tanks nationwide. The breathing valve baffle is a manufacturing simple, easy to install (not moving fire, can not distinguish cans), does not affect the normal operation of production, less investment, quick energy saving equipment, suitable
