Abstract

The invention discloses a central drainage system for an outer floating roof storage tank. The system comprises a floating disc (1), a water collecting pit (2) and a drainage port (3), and further comprises an S-shaped central drainage pipe (4) arranged in an inner cavity of the storage tank and multiple counterweight blocks (5) fixed on the central drainage pipe (4). The invention further discloses a counterweight method of the central drainage system; and along the upper end to the lower end of a pipe body, gaps between any counterweight blocks (5) and the next adjacent counterweight blocks (5) besides the first and final counterweight blocks are smaller than and equal to gaps between any counterweight blocks (5) and the previous adjacent counterweight blocks (5). The central drainage system is simple in structure, fewer in bonding joints, low in leakage possibility, long in service life and convenient for installation and maintenance, and can prevent the pipe body from floating and moving to wind with surrounding support columns (7).

Description

Technical field [0001] The invention relates to a central drainage system for an external floating roof storage tank, and also relates to a counterweight method for the central drainage system of an external floating roof storage tank. Background technique [0002] The outer floating roof storage tank is a common open storage tool in the petrochemical industry. It mainly includes a columnar tank with an open top, a floating plate and a pillar vertically arranged at the bottom of the floating plate. The outer edge of the floating plate matches the inner wall of the tank. It forms a closed tank cavity with the tank body, and the floating plate rises and falls with the change of the oil storage volume in the tank cavity. Because the outer floating roof storage tank is directly exposed to the external environment, and the floating plate is lower than the upper edge of the tank body, the rain and snow in nature will directly fall and accumulate on the upper surface of the floating pla...
