Oil collection tank having expansion ring, and application thereof

Abstract

The present invention relates to an oil collection tank having an expansion ring, and an application thereof. The oil collection tank comprises a liquid collection cap, a liquid collection groove, a liquid collection groove position limitation device, a tower ring, a filler plate, a position limitation expansion ring, a bracket, a liquid collection channel, a pulling-out hopper and a support rib plate. One end of the liquid collection groove is fixed on the liquid collection channel, and the other end is fixed on the filler plate. The liquid collection groove position limitation device is arranged on the lower part of the filler plate connected to one end of the liquid collection groove. The lower part of the other end of the filler plate is overlapped on the tower ring. The upper part of the filler plate is connected with the position limitation expansion ring. The oil collection tank of the present invention has the following advantages that: excellent functions of gas distribution and liquid collection are provided, staying time of the collected liquid can be reduced, occurrence of coking can be prevented, the oil collection tank can freely expand at a high temperature without limitation of operating temperature, and normal operation of the tower under the high temperature operating condition is ensured.

Description

technical field [0001] The invention relates to an internal part of a chemical tower, in particular to a full-communication disc type oil collection tank with an expansion ring for liquid collection and gas distribution in a large chemical tower and its application. Background technique [0002] In the departments of oil refining, petrochemical, fine chemical, food, medicine and environmental protection, towers are important unit equipment with a large volume and wide range, and their investment generally accounts for more than 20% of the total investment, and some even as high as 50%. Columns are widely used in unit operations such as distillation, absorption, extraction, washing, and heat transfer. Therefore, the research on towers has always been an important issue that scholars at home and abroad have generally paid attention to. [0003] With the development of tower equipment, the technology of tower internals has also been continuously developed and improved. Various...

Problems solved by technology

[0004] However, after the application in various large-scale towers in recent years, it is found that although the disc-type oil collection tank can obviously improve the contradiction between liquid collection and gas distribution, the traditional disc-type oil Under normal conditions, due to the large thermal deformation, it often affects the normal operation, and even causes thermal deformation and damage at the junction of the sump of the oil tank and the tower ring

Therefore, the traditional disc oil collection tank cannot solve the problem of thermal expansion at high temperature
