Abstract

The invention relates to the technical field of safe collection of volatile organic compounds (VOCs) in normal pressure and low pressure storage tanks, and discloses a safe collection device for VOCsin storage tanks. The device comprises storage tank groups of various materials, air extraction equipment and oil-gas treatment equipment. According to the device, not only is the fire risk of the storage tanks significantly reduced, but also the gas phase of the storage tanks can be remotely cut off in case of an accident so that the safety of the storage tanks can be guaranteed. Meanwhile, the device achieves the VOCs treatment of the various material storage tanks.

Description

technical field [0001] The invention relates to the technical field of safe collection of volatile organic compounds in normal pressure and low pressure storage tanks, in particular to a storage tank VOCs safe collection device. 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 present, the storage...
