Abstract

The invention discloses an oil storage tank and pipe safe double-joint-defense system. An optical fiber is provided with an optical fiber pressure sensor and an optical fiber temperature sensor, has double sensing functions, and is high in sensitivity, signals are received by a light receptor and are decoded into digital signals, the digital signals are transmitted to an early warning system for data analysis, temperature and pressure threshold values or temperature change and pressure change early warning threshold values can be set, once one of the early warning threshold values is exceeded,an automatic control device can be triggered to control a feeding oil pump to be closed and a discharging oil pump to be started, and the safety of the oil storage tank is ensured in a double way. The oil storage tank and pipe safe double-joint-defense system is further provided with an automatic control system and a manual control device which control opening and closing of an oil delivery pump,change of temperature and pressure is directly monitored through a display, once an early warning threshold value is exceeded and when the early warning system fails, the feeding oil pump and the discharging oil pump are started or closed through the manual control device, and a double-joint-defense effect and a double-guarantee effect on the safety of the oil storage tank and oil delivery safetyare achieved.

Description

technical field [0001] The invention relates to the technical field of oil storage tanks and pipeline transportation safety, in particular to a dual protection system for oil storage tanks and pipeline safety. Background technique [0002] With the sharp increase in demand for oil and the increase in imports of my country's strategic oil reserves, oil storage tanks are developing in the direction of large-scale storage. The storage capacity of a single tank has exceeded 150,000 cubic meters. The imported oil comes from all over the world, with diversified and complex components. There is no shortage of high-sulfur crude oil; and high-sulfur crude oil needs to be desulfurized before refining. In order to fully and effectively desulfurize the desulfurizer, the desulfurizer is usually added on the pipeline before the oil is transported into the storage tank. , but the desulfurizer itself is highly corrosive and oxidizing, and when the concentration is too high, it will chemically...
