Abstract
The invention discloses an active protection structure for a primary sealing space of an external floating roof type oil storage tank. The external floating roof type oil storage tank comprises a tank wall and an external floating roof arranged in the oil storage tank, wherein primary and secondary sealing spaces are formed between the tank wall and the external floating roof through a primary sealing oil gas diaphragm and a secondary sealing oil gas diaphragm, a secondary sealing baffle is arranged on the outer side of the secondary sealing oil gas diaphragm, the primary sealing oil gas diaphragm, the secondary sealing oil gas diaphragm and the secondary sealing baffle are fixedly connected with the external floating roof through connecting bolts, one end of the connecting bolt is arranged in the primary sealing space, each connecting bolt is of a hollow structure, and the primary sealing space is communicated with an inert gas generating device or/and an oil gas sampling device through connecting bolts having the hollow structures. The active protection structure disclosed by the invention can be used for conveying an inert protective medium and an oil gas sample into the primary sealing space on the condition of not changing the original structure of the oil storage tank and performing no additional machining.
Description
Technical field
The invention belongs to the security against fire technical field, be specifically related to the active fail-safe structure in a kind of outer floating roof formula petroleum storage tank once sealing space.
Background technology
At present, the outer floating roof large-scale petroleum storing tank of domestic employing mechanical seal mode, because the sealing position of its floating roof exists certain density oil vapour and oxygen, this position at thunderstorm season owing to thunderbolt very easily causes explosive combustion that serious accident occurs.If by pipeline with the inactive protect medium (such as N
2) be injected into once with the secondary seal space in, its oxygen and gas concentration are down in the safe range, can realize the anti-lightning strike safety precaution to storage tank.But have now at the petroleum storage tank of usefulness because its high demand to safety, do not allow to carry out the machine up operations such as similar boring, cutting at tank body and floating roof, therefore, outside existing on the basis of floating roof petroleum storage tank structure, active protection method for outer floating roof large-scale petroleum storing tank only can carry out for the seal cavity between first and second sealing active protection, and can't carry out the active protection to the once sealing space.
Summary of the invention
The object of the invention is to: for the problem of above-mentioned existence; provide a kind of and do not changed original structure; do not need to carry out extra machine up yet, just can carry the inactive protect medium in the once sealing space or carry out the active fail-safe structure in the outer floating roof formula petroleum storage tank once sealing space of oil gas sampling.
The technical scheme of the technology of the present invention is achieved in that the active fail-safe structure in a kind of outer floating roof formula petroleum storage tank once sealing space, described outer floating roof formula petroleum storage tank comprises tank skin and is arranged on the interior outer floating roof of petroleum storage tank, between described tank skin and outer floating roof, form one by once sealing oil gas barrier film and secondary seal oil gas barrier film, the secondary seal space, in described secondary seal oil gas barrier film arranged outside the secondary seal baffle plate is arranged, it is characterized in that: described once sealing oil gas barrier film, secondary seal oil gas barrier film is all captiveed joint with outer floating roof by tie bolt with the secondary seal baffle plate, one end of described tie bolt places in the once sealing space, described tie bolt is hollow structure, the tie bolt of described once sealing space by hollow structure with inert gas generator or/and the oil gas sampling setup be communicated with.
The present invention replaces with the tie bolt of hollow structure by having the tie bolt that is used for fixed connection and sealing oil gas barrier film and closing plate in the outer floating roof large-scale petroleum storing tank structure now; do not changing the petroleum storage tank original structure; also do not carry out in the situation of extra machine up; both fixed oil gas barrier film and sealing baffle, and realized again in the once sealing space, carrying inactive protect medium and oil gas sampling by the tie bolt of hollow structure.
Description of drawings
Fig. 1 is structural representation of the present invention.
Mark among the figure: 1 is tank skin, and 2 is outer floating roof, and 3 is once sealing oil gas barrier film, and 4 is secondary seal oil gas barrier film, and 5 is the once sealing space, and 6 is the secondary seal space, and 7 is the secondary seal baffle plate, and 8 is tie bolt, and 9 is leaf spring.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the technology of the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, the active fail-safe structure in a kind of outer floating roof formula petroleum storage tank once sealing space, described outer floating roof formula petroleum storage tank comprises tank skin 1 and is arranged on the interior outer floating roof 2 of petroleum storage tank, between described tank skin 1 and outer floating roof 2, form one by once sealing oil gas barrier film 3 and secondary seal oil gas barrier film 4, secondary seal space 5,6, in described secondary seal oil gas barrier film 4 arranged outside secondary seal baffle plate 7 is arranged, described once sealing oil gas barrier film 3, secondary seal oil gas barrier film 4 is all captiveed joint with outer floating roof 2 by tie bolt 8 with secondary seal baffle plate 7, one end of described tie bolt 8 places in the once sealing space 5, described tie bolt 8 is hollow structure, described once sealing space 5 tie bolt 8 by hollow structure with inert gas generator or/and the oil gas sampling setup be communicated with.
Wherein, in once sealing space 5, be provided with leaf spring 9 between pasta and the once sealing oil gas barrier film 3.
Adopt structure of the present invention; do not changing the petroleum storage tank original structure; also do not carry out in the situation of extra machine up; both fixed oil gas barrier film and sealing baffle, and realized again in the once sealing space, carrying the inactive protect medium and carrying out the function that oil gas is sampled with special angle by the tie bolt of hollow structure.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
