Description
Technical Field
The utility model relates to a passive fire protection system among the ocean oil gas engineering especially relates to fire door structure is prevented to ocean oil gas platform.
Background
For the FPSO, the oil and gas treatment equipment is mainly arranged on the process module and is positioned in an open area, and when a fire disaster happens, the fire condition is extremely easy to expand to the adjacent area. In order to control the spread of a fire, the necessary safeguards are required, in which case the performance of the fire door is of critical importance.
In the existing fireproof door structure, a fireproof expansion sealing element is generally directly adhered to a cut surface of a door frame, so that a certain gap exists between the door frame and a door leaf, and the effect of blocking thick smoke is unsatisfactory. The fireproof expansion sealing element is easy to fall off due to the fact that the door leaf is opened and closed for a long time, and meanwhile, electromagnetic shielding is often needed to be carried out in important spaces of the oil-gas platform, and normal operation of internal equipment in the space of the oil-gas platform is guaranteed.
The existing fireproof door structure is not strong in sealing performance, toxic smoke easily overflows from a door gap when a fire disaster occurs, further spreading of the fire disaster is caused, and a good electromagnetic shielding effect cannot be formed at a door opening under the normal state, so that an electromagnetic signal can affect an oil-gas platform.
Disclosure of Invention
An object of the utility model is to overcome prior art's is not enough, provides a fire door structure is prevented to ocean oil gas platform, should prevent that fire door has the performance sealed, fire prevention and electromagnetic shield, not only improves the sealing performance when the fire door is closed, still has electromagnetic shield function.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model relates to a fireproof door structure of an ocean oil and gas platform, which comprises a door frame arranged on a reserved door opening of an oil and gas platform wall, the right wall of the fireproof door is rotationally connected with the door frame through a door shaft, a first labyrinth seal strip is arranged between the left end of the outer wall of the fireproof door positioned outdoors and the door frame, a second labyrinth seal strip is arranged between the right wall of the fireproof door provided with the rotating shaft and the door frame, the first labyrinth seal strip and the second labyrinth seal strip have the same structure and are made of fireproof expansion materials, each labyrinth seal strip comprises a door frame end seal strip fixed on the door frame and a door end seal strip arranged opposite to the door frame end seal strip and fixed on the fireproof door, the opposite surfaces of the door frame end sealing strip and the door end sealing strip are respectively provided with a concave-convex alternately arranged structure, when the fireproof door is closed, the concave-convex structures of the door frame end sealing strip and the door end sealing strip are embedded and connected with each other to form a sealing structure.
The structure has the performances of sealing, fire prevention and electromagnetic shielding, not only improves the sealing performance when the fireproof door is closed, but also has the electromagnetic shielding function.
Drawings
Fig. 1 is a top view of the fireproof door structure of the offshore oil and gas platform of the present invention;
figure 2 is a horizontal cross-sectional view of the fire rated door structure of figure 1;
FIG. 3 is a side view of the labyrinth seal interface shown in FIG. 1.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in the attached drawings, the utility model relates to a fire door structure of ocean oil gas platform, including installing door frame 1 on the door opening of reserving of oil gas platform wall, prevent fire door 3 right wall through door-hinge 4 and door frame 1 rotation connection, prevent fire door be located outdoor left end of outer wall and install first labyrinth sealing strip 2 between the door frame 1, install second labyrinth sealing strip 5 between prevent fire door 3 right wall and the door frame 1 of installing the pivot, first labyrinth sealing strip 2 and second labyrinth sealing strip 5 the same structure and all adopt fire prevention expanding material, each labyrinth sealing strip all includes door frame end sealing strip 16 and door frame end sealing strip 16 relative arrangement and fix the door end sealing strip 15 on preventing fire door fixed on the door frame respectively, have the structure that unsmooth alternative set up respectively on the opposite face of door frame end sealing strip 16 and door end sealing strip 15, when the fire door 3 is closed, the concave-convex structures of the frame end seal 16 and the door end seal 15 are embedded and connected with each other to form a sealing structure. The fireproof expansion material can be ethylene propylene diene monomer (foaming, closed cell), nitrile, rubber, silica gel, neoprene, polyurethane rubber, thermoplastic vulcanized rubber, plasticized polyvinyl chloride and the like.
Preferably, the fireproof door 3 comprises an electromagnetic shielding layer 10, a heat insulation layer 11, an outer flame-retardant layer 12 and a metal door plate 13 are symmetrically fixed on the front side and the rear side of the electromagnetic shielding layer 10 from inside to outside in sequence, and a fireproof paint layer 14 is coated on the metal door frame 13, so that the fireproof door has a certain fireproof function.
Preferably the left wall mounting of preventing fire door 3 a door end bonding block 7, door end bonding block 7 be connected with electromagnetic shield layer 10, install one can with door end bonding block 7 door frame end bonding block 6 of inhaling mutually on door frame 1, door end bonding block 7 with door frame end bonding block 6 contact, can form shielding effect to the topography.
The working principle is as follows:
under the usual state, prevent fire door is in the closed condition, form sealedly to oil gas platform through using first labyrinth sealing strip 2 and second labyrinth sealing strip 5, prevent that fire door's electromagnetic shield layer 10 can shield the communication signal on the oil gas platform, thereby form certain guard action to oil gas platform inner space, when the conflagration breaing out, first labyrinth sealing strip 2 and second labyrinth sealing strip 5 take place deformation under hot effect, receive the restriction mutual extrusion of structure, form good sealed effect and realize smoke protection performance, and prevent that fire door 3 top layer's fireproof paint layer 14 forms preliminary separation to the conflagration, the further emergence of conflagration along with the lapse of time, fire-retardant layer 12 forms further separation to the conflagration, thereby reserve out longer escape time for relevant personnel.
