Problems solved by technology

This protection mode consumes a lot of inert gas; and it cannot solve the hidden danger of the container sucking air under the internal negative pressure state, and the reliability of protection is very poor. Due to changes in liquid level, temperature, pressure or condensation inside the container The equal phase change causes a relative negative pre

Embodiment Construction

[0015] An inert gas protection device for an inflammable and explosive material container. The device includes a material tank 1. The top of the material tank 1 is connected to a liquid sealing tank 3 through an overflow pipe 6, and the overflow pipe 6 reaches the bottom of the liquid sealing tank 3. The top of the buffer tank 2 is connected to the top of the material tank 1 via a gas supply pipe 5, the top of the buffer tank 2 is also connected to an inert gas supply device 4 via an inert gas supply line 12, and an emergency pressure relief pipe 7 is also provided on the top of the material tank 1.

[0016] The bottom of the material tank 1 is also provided with a material pump 13; the inside of the top of the material tank 1 is provided with an oxygen content detection meter 14 and a second pressure gauge 15.

[0017] The upper part of the liquid-sealed tank 3 is also provided with a liquid-sealed emptying pipe 8 and a replenishing port 9, and the side wall of the liquid-sealed ta...

Abstract

The invention relates to a device which uses insert gases for protecting a container for volatile flammable and explosive materials. According to the device, the top of a material tank is connected with a liquid seal trough through a gas overflowing pipeline, and the gas overflowing pipeline goes deep into the bottom of the liquid seal trough; the top of a buffer tank is connected with the top of the material tank through a gas supply pipeline and is further connected with an inert gas supply device through an inert gas supply pipeline; the top of the material tank is further provided with an emergency pressure relief pipe. The device can guarantee that the upper space of the material tank achieves automatic high-pressure exhausting, automatic high-oxygen-content gas supply and automatic low-pressure gas supply, prevents air from entering the container, and lowers the probability of explosion accidents of the container. The device has the advantages of being simple in structure, high in safety and low in cost, and can be widely applied to anti-explosion prevention and protection for containers for volatile flammable and explosive materials such as oil products, alcohol and aldehyde in the relevant industries of petroleum, chemical engineering and the like.

Description

Technical field [0001] The invention relates to a protection device for flammable and explosive containers, in particular to an inert gas protection device for flammable and explosive material containers. Background technique [0002] Explosion of volatile, flammable and explosive material containers (including storage tanks and pipelines) is one of the common types of accidents in the industrial production process. The explosion limit is an important parameter of the material system, and it is also the focus of the explosion prevention work. weight. The gas space at the top of the container for volatile, flammable and explosive materials is a complex mixture of components. For a single combustible and explosive substance, its explosion limit generally has a fixed range; but in a mixed system of multiple components, its explosion limit is not fixed, not only changes with the composition, and the initial temperature, The system pressure, the content of the inert medium, the spac...
