Abstract

The invention relates to the technical field of normal-pressure and low-pressure storage tank VOCs collection and emission and discloses a storage tank VOCs emission low-pressure gas system safety device. The device comprises a storage tank group for multiple types of materials, emission equipment, a torch pipe network, a water-sealed tank, a gas tank and a fire tank. The safe and environment-friendly storage tank VOCs emission low-pressure gas system is designed by the invention, and the fire risk of storage tanks is reduced; and meanwhile, treatment of VOCs of the storage tanks for the multiple types of materials is further achieved.

Description

technical field [0001] The invention relates to the technical field of VOCs collection and discharge of normal pressure and low pressure storage tanks, in particular to a safety device for a storage tank VOCs discharge low pressure gas system. Background technique [0002] Odor gas emissions caused by the breathing of storage tanks, the volatilization of residual oil, the shutdown of cleaning lines, and the volatilization of solvents carried in oil have become a major source of air pollution in petroleum, petrochemical, and chemical companies. They are volatile organic compounds (VOCs ) is one of the main sources. As the country pays more and more attention to environmental protection, relevant regulations and standards are becoming increasingly strict. In order to meet the requirements of national laws and regulations, various refining and chemical companies have begun to implement large-scale VOCs collection and treatment projects in oil storage systems. [0003] At prese...
