Problems solved by technology

[0002] The oil in the existing oil storage tank is evaporated due to the temperature difference between day and night, and the oil is volatilized due to the agitation of oil extraction and oil filling. The volatilization speed of the oil surface makes the oil storage tank to the inner cavity of the tank top full of a large amount of oil and gas, and there is a hidden danger of oil and gas combustion and explosion caused by lightning strikes and static electricity

Abstract

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.

Description

technical field [0001] The invention belongs to the field of fire safety in the petroleum and petrochemical industry, and in particular relates to a safety protection device for an oil storage tank and a protection method thereof. Background technique [0002] The oil in the existing oil storage tank is evaporated due to the temperature difference between day and night, and the oil is volatilized due to the agitation of oil extraction and oil filling. The volatilization speed of the oil surface makes the oil storage tank to the inner cavity of the tank top full of a large amount of oil gas, and there is a hidden danger of oil gas combustion and explosion caused by lightning strikes and static electricity. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems and provide a safety protection device for oil storage tanks that can effectively inhibit the evaporation of the oil surface, and can also recover and process ...
