Abstract

The invention discloses a structure and a method for self-flushing an oil collecting tank. The structure and the method are used for flushing the oil collecting tank in a tower device containing a large number of solid particle systems and materials prone to coking under the special conditions of high-temperature operation and the like. An extraction flushing process is added outside the tower, and a special flushing structure is arranged in the tower to realize continuous or intermittent online flushing of a liquid collecting ring, a bottom plate and coking or deposited solids in a liquid collecting channel in a specially designed structure in the oil collecting tank during normal operation, so the coking and depositing phenomena in the oil collecting tank can be eliminated or relieved tothe maximum extent, thereby long-period operation of the device and stable operation of the device are guaranteed. The method makes the actual production of industrial devices of needle coke become possible.

Description

technical field

[0001] The invention relates to a tower equipment operation process and internal components in the field of petroleum engineering, in particular to a self-flushing structure of an oil collection tank and a flushing method based on the structure. Background technique

[0002] The oil collection tank is an internal component of tower equipment widely used in oil refining, chemical, and coal chemical industrial installations. It is a collection device for liquid materials such as the upper part of the tower that flows to the lower part or feed. The main types of oil collection tanks include disc liquid collectors, grooved plate liquid collectors, finned liquid collectors, etc. Among them, the disc type and grooved plate oil collection tanks are mainly composed of extraction buckets, liquid collection channels, and liquid collection rings. It is composed of a bottom plate, a riser pipe, and a riser cap. Generally, the liquid collection ring around the air riser ...
