An oil storage tank oil inlet device

Abstract

The invention discloses an oil inlet device for an oil storage tank. The oil inlet device of the oil storage tank includes a horizontally arranged oil inlet pipeline (5) and a diameter-expanding pipe (7), and the oil inlet pipeline (5) and the diameter-expanding pipe (7) are connected through a large and small head (6). The outlet of the expanding pipe (7) is an oil outlet (13), and the oil outlet (13) is arranged obliquely downward relative to the horizontal plane. A top plate (9) is provided above the diameter expansion pipe (7), a support plate (8) is provided between one end of the top plate (9) and the diameter expansion pipe (7), and the other end of the top plate (9) is connected to the vertical plate (10 ) are connected, and the bottom of the vertical plate (10) is fixed on the oil storage tank bottom plate (3). A buffer baffle (11) is arranged opposite to the oil outlet (13) in the horizontal direction, and the buffer baffle (11) is located between the oil outlet (13) and the vertical plate (10), and the buffer baffle (11) and Springs (12) are arranged between the vertical plates (10). The invention can be used for the oil storage tank of the oil product storage and transportation system of petrochemical enterprises.

Description

technical field [0001] The invention belongs to the field of oil storage and transportation systems for petrochemical enterprises, and relates to an oil inlet device for an oil storage tank. Background technique [0002] In the oil storage and transportation system, the oil enters the oil storage tank through the oil outlet of the oil inlet pipeline. Controlling the flow rate of the oil outlet is an important measure to ensure the safe production and operation of the oil storage tank in petrochemical enterprises. According to the requirements of the national standard GB13348-2009 "Electrostatic Safety Regulations for Liquid Petroleum Products", during the filling process, the oil should be prevented from flying and splashing. In addition, when there is obviously an incompatible second phase in the oil inlet pipeline, the oil flow rate should be controlled below 1 m / s to prevent electrostatic hazards. There are generally two types of existing oil inlet devices for oil storag...
