Problems solved by technology
This sealing method cannot effectively solve the problems of volatilization of oil and gas caused by crude oil hanging on the wall of the storage tank and volatilization of oil and gas on the guide column, and the volatilization of oil and gas at these two places accounts for a large proportion of the volatilization of the leakage of the storage tank
It not only causes environmental pollution, oil and gas loss, but also forms a large-scale explosion area, which is easy to cause fire accidents caused by lightning strikes, and brings huge potential safety hazards

Embodiment Construction
[0016] The specific embodiment of the present invention is further described below in conjunction with accompanying drawing:
[0017] Such as figure 1 As shown, a floating roof storage tank that suppresses volatilization of oil and gas includes a tank body 1, a floating plate 2, a guide column 3 passing through the floating plate 2, a sealing sleeve 4 outside the guide column 3, and a fixed metal on the top of the tank body 1 Plate 6, the ventilation device 7 on the fixed metal plate 6, the connecting pipe 5 connecting the sealing sleeve 4 and the fixed metal plate 6 and the sealing film 8 connecting the fixed metal plate 6 and the floating plate 2, the fixed metal plate 6 is along the tank body 1 The top is installed around the top, and both the sealing sleeve 4 and the sealing film 8 are scalable. The material of the sealing film 8 is rubber. The retractable sealing film 8 forms a closed space with the floating plate 2, the tank body 1, and the fixed metal plate 6, so that ...

The invention belongs to the technical field of storage tank sealing and discloses a floating roof storage tank for inhibiting volatilization of oil gas. The floating roof storage tank for inhibitingvolatilization of oil gas comprises a tank body, a floating tray, a guide pillar through the floating tray, a sealing sleeve out of the guide pillar, a fixed metal plate on the top of the tank body, aventilating device on the fixed metal plate, a communicating pipe connecting the sealing sleeve and the fixed metal plate and a sealing membrane connecting the fixed metal plate and the floating tray, wherein the fixed metal plate is mounted around the top of the tank body; a fire barrier is arranged in the ventilating device; the sealing sleeve and the sealing film are scalable; the sealing film, the floating tray, the tank body and the fixed metal plate form a closed space, so that oil gas can not leak easily and only communicates to atmosphere through the ventilating device during oil feeding and discharging operations, and therefore, volatilization of oil gas in daily operation of the storage tank is reduced greatly; the leakage rate of oil gas on the tank wall is reduced by over 99%;the ventilating device with the fire barrier can block flame propagation in a fire accident, so that fire of the storage tank caused by an external fire source is avoided.
Description
technical field [0001] The invention relates to the sealing of storage tanks, in particular to a floating roof storage tank which suppresses volatilization of oil and gas. [0002] technical background [0003] Petroleum is an important strategic material, which is related to the development of the national economy and the stability of the society. At present, the country has established a number of large national oil reserve bases, and the current sealing method is mainly primary sealing and secondary sealing. This sealing method cannot effectively solve the problems of volatilization of oil and gas formed by crude oil hanging on the wall of the storage tank and volatilization of oil and gas on the guide column, and the volatilization of oil and gas at these two places accounts for a large proportion of the volatilization of the leakage of the storage tank. It has not only caused environmental pollution, oil and gas loss, but also formed a large-scale explosion area, which ...
