Safety control system suitable for oil storage tank valve

Abstract

The invention relates to a safety control system suitable for an oil storage tank valve. Comprising a manual-automatic integrated valve, a microprogram controller, a smoke alarm, a non-contact thermodetector, a combustible gas detector, an alarm, an overpressure deflation valve with an activated carbon adsorption layer, a photovoltaic solar panel, a solar controller, a storage battery, a fire-fighting foam tank, a transfer pump and a fire-fighting liquid spraying pipeline with a nozzle. A manual-automatic integrated valve is generally used for automatically controlling the valve to be opened and closed, and if a tank area is powered off, a storage battery is used for supplying power only in an emergency through manual control. And if the smoke alarm or the non-contact thermodetector or the combustible gas detector detects a fire signal, the microprogram controller automatically controls the valve to be closed and gives an alarm. And if the indexes of the three sensors are not reduced after the valve is closed, the fire-fighting liquid spraying pipeline automatically sprays out fire-fighting liquid to cool the periphery of the tank body. The invention provides a safety control system which is simple and intelligent to operate and convenient to maintain and manage.

Description

technical field [0001] The invention belongs to the technical field of oil tank safety equipment, and in particular relates to a safety control system suitable for oil storage tank valves. Background technique [0002] There are often a large number of oil tanks distributed in the storage tank area of ​​petrochemical products, and various pipelines are densely distributed, and the overall capacity of the storage tank is relatively large. After a storage tank fire occurs, it is very easy to cause a fire in the surrounding storage tanks. At the same time, the explosion phenomenon caused by it is also persistent, not a one-time explosion. However, due to different combustion conditions in oil tank fires, one or more of the following situations will occur: explosion first and then combustion, first combustion and then explosion, local stable combustion without explosion, and no longer burning after explosion. Among them, the oil tank fire that burns first and then explodes is m...

AI Technical Summary

Problems solved by technology

If dangerous situations such as fire and explosion occur in the storage tank, it will not only cause huge property losses, but also cause casualties and great harm

In addition, the flame temperature of the storage tank fire is relatively high, theoretically it can reach 1400°C, even the temperature of the tank wall can reach above 1000°C, and a large amount of oil vapor will be generated. This kind of gas is highly toxic and greatly affects Difficulty of fire rescue
