Oil storage tank with zero emission of pollutants

Abstract

The invention discloses an oil storage tank with zero pollutant discharge. The storage tank comprises a tank wall, a tank top, a tank bottom, a floating disc, an oil gas collecting bag, an oil bag, a telescopic pipe, a hose, an oil gas outlet and a breathing opening. The oil gas outlet and the breathing opening are located in the top or the wall of the storage tank. The floating disc is provided with an oil gas collecting bag, and the oil gas collecting bag protrudes out of the floating disc and is fixedly connected with the floating disc; the oil bag is of a cylindrical structure and can be folded or contracted up and down, the circumference of the upper edge of the oil bag is fixedly connected with the edge of the floating disc, and the circumference of the lower edge of the oil bag is hermetically and fixedly connected with the lower part of the tank wall; the telescopic pipe is used for supporting the floating disc and maintaining stable operation of the floating disc, the bottom end of the telescopic pipe is fixedly connected with the tank bottom, and the top end of the telescopic pipe is fixedly connected with the bottom face of the floating disc. The storage tank does not discharge pollutants to the environment, and has the advantages of safety, reliability, simple equipment and the like.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy saving, in particular to an oil storage tank with zero discharge of pollutants. Background technique [0002] During the storage and transportation of oil products and chemicals, a large amount of oil gas or volatile organic compounds (VOCs) escape. According to statistics, the annual loss of light oil products accounts for about 0.5% of light oil products. On the one hand, it leads to a large amount of waste of oil and gas or volatile organic compounds, reducing the economic benefits of enterprises, and on the other hand, it leads to serious environmental pollution. . In addition, since oil and air can easily form explosive mixtures (the lower explosion limit is generally 1% to 6%), the escape of oil and gas will cause the concentration of oil and gas around the corresponding facilities to easily reach the explosion limit, and the oil and gas accumulated on the ground...
