Zusammenfassung: | The invention discloses an oil product storage tank safety protection device and protection method. The oil product storage tank safety protection device comprises a gas analyzing unit, an inhibitor supply unit and a control unit, the gas analyzing unit is connected with a mixed gas space formed above the liquid surface of oil product in the oil storage tank, the inhibitor supply unit is connected with the oil storage tank through an inhibitor supply pipe, and the control unit is respectively connected with the gas analyzing unit and inhibitor supply unit. The oil product storage tank safety protection device and protection method are mainly used for flammable and combustible spaces formed by oil evaporation in crude oil storage tanks and product oil tanks, the gas analyzing unit detects the concentration of the mixed gas in the space above the liquid surface of the oil product in the oil storage tank, the inhibitor supply unit fills inhibitor to the surface of the oil product in the oil storage tank, and the filled inhibitor can form a liquid film protection layer at the surface of the oil product and reduce the oil gas evaporation and volatilization of the oil product; the oil gas concentration is reduced through the evaporation of the liquid film, and accordingly the inactive protection for the oil gas space is realized. |
