Abstract

The utility model relates to a smoke exhaust system of a main generator unit of a marine-petroleum drilling platform, in particular to a smoke-exhaust-pipe cabin penetrating piece in the smoke exhaust system. The smoke-exhaust-pipe cabin penetrating piece is characterized in that an insulating layer is sheathed outside the smoke exhaust pipe; a steel plate I penetrates through the insulating layer to be welded with the smoke exhaust pipe; a steel plate II is welded with a semicircular steel pipe which is welded with a composite plate; the composite plate is welded with a cabin wall; and a heat-insulating gasket is arranged between the steel plate I and the steel plate II and is fixed by a bolt, a nut and a spring gasket. The smoke-exhaust-pipe cabin penetrating piece has the advantages that the occupied space of the cabin penetrating piece is small, no corrosion is caused to the smoke exhaust system, and the maintenance and the disassembly are convenient; and the defects of large occupied space, corrosion of seawater to the smoke exhaust pipe and inconvenience in maintenance and disassembly of the existing water-jacket cabin penetrating piece are overcome.

Description

Smoke exhaust pipe crossing cabin spare

Technical field:

The utility model relates to a kind of offshore oil drilling platform main generator group fume exhaust system, particularly smoke exhaust pipe crossing cabin spare in a kind of fume exhaust system.

Background technology:

Smoke exhaust pipe crossing cabin spare is mainly used on the fume exhaust system of offshore oil drilling platform main generator group, the Main Function of fume exhaust system is that the waste gas of diesel engine is discharged outboard smoothly, when smoke exhaust pipe passes bulkhead, smoke exhaust pipe crossing cabin spare need to be set, the Main Function of crossing cabin spare is to prevent that the heat on the smoke exhaust pipe from passing on the bulkhead, guarantees again smoke exhaust pipe dismounting, easy to maintenance simultaneously.At present, the domestic water jacket crossing cabin spare that in fume exhaust system, adopts, this water jacket crossing cabin spare ubiquity is following not enough:

1, in order to guarantee that enough cooling water inflows reduce the temperature of smoke exhaust pipe, the cooling chamber that forms between water jacket crossing cabin spare and the smoke exhaust pipe need to have enough spaces, so water jacket crossing cabin spare volume ratio is larger, is subjected to space constraint when arranging.

2, water jacket crossing cabin spare needs cooled with seawater, because seawater has stronger corrosive property, long-term use can cause the smoke exhaust pipe corrosion damaged.

3, maintenance and dismounting smoke exhaust pipe are inconvenient.

The utility model content:

The technical problems to be solved in the utility model provides a kind of smoke exhaust pipe crossing cabin spare, this device realized crossing cabin spare take up room little, do not have corrosive property and repair demolition convenient to smoke exhaust pipe.Overcome that existing water jacket crossing cabin spare takes up room greatly, seawater is to the deficiency of smoke exhaust pipe corrosion and repair demolition inconvenience.

Technical solution adopted in the utility model is: a kind of smoke exhaust pipe crossing cabin spare comprises insulating barrier; Insulating barrier is sleeved on outside the smoke exhaust pipe, the steel plate I is passed insulating barrier and smoke exhaust pipe welding, steel plate II and semicircle steel-pipe welding, semicircle steel pipe and compound plate welding, the welding of compound plate and bulkhead is equipped with heat insulating mattress and fixes by bolt, nut and spring shim between steel plate I and the steel plate II.

The beneficial effects of the utility model are: the utility model is because the mode that has adopted insulating barrier and smoke exhaust pipe and bulkhead have been isolated by heat insulating mattress, thus have crossing cabin spare take up room little, smoke exhaust pipe is not corroded and repair demolition advantage easily.

Description of drawings:

The utility model is described in more detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment:

As shown in Figure 1 and Figure 2, a kind of smoke exhaust pipe crossing cabin spare comprises insulating barrier 10, and insulating barrier 10 is sleeved on outside the smoke exhaust pipe; Steel plate I 4 is passed insulating barrier 10 and smoke exhaust pipe welding, steel plate II 6 and 7 welding of semicircle steel pipe, semicircle steel pipe 7 and compound plate 8 welding, compound plate 8 and bulkhead 9 welding are equipped with heat insulating mattress 5 and fixing by bolt 1, nut 2 and spring shim 3 between steel plate I 4 and the steel plate II 6.

Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
