Abstract

The invention relates to the safety technical field of normal-pressure and low-pressure storage tank volatile organic compound safe collecting and discharging open flame equipment, and discloses a safety device of the storage tank VOCs discharging open flame equipment. The safety device comprises a storage tank group of a plurality of materials, gas extraction equipment and the open flame equipment. According to the safety device, the gas-phase space of storage tanks can be effectively controlled to prevent an explosive environment from being formed, so that the risk of fire disasters in the storage tanks is reduced; moreover, forming of explosive gas in a pipeline before entrance into the open flame equipment can be dually prevented, so that the absolute safety of the open flame equipmentis ensured. Meanwhile, the safety device also realizes the treatment of various material storage tank VOCs.

Description

technical field [0001] The invention relates to the technical field of safe collection and discharge of volatile organic compounds in normal pressure and low pressure storage tanks, in particular to a safety device for storage tank VOCs discharge open flame equipment. 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 sy...
