The utility model provides a protection device for installing on marine emergency generator blast pipe separates blast pipe and bulkhead through this protection device, ensures that the heat of blast pipe is not direct to be transmitted for hull structure, protection hull bulkhead structure.
Referring to fig. 1, the present embodiment shows a specific structure of an exhaust pipe protection device in an embodiment. The exhaust pipe protection device comprises a first pipeline 3 fixedly connected to a cabin wall 102, and a second pipeline 2 arranged outside the cabin and communicated with the first pipeline 3, wherein the first pipeline 3 and the second pipeline 2 can be coaxially arranged. Offer the through-hole that supplies first pipeline 3 to insert on bulkhead 102, first pipeline 3 communicates with the cabin, first pipeline 3 can select the steel pipe, wherein wall thickness class (Sch) can select Sch160, the material of its steel pipe further can select seamless steel pipe or welding steel pipe, make its steel pipe finished pipe form, can insert it in the through-hole in the segmentation pre-outfitting stage, the outer wall of first pipeline 3 and the junction of bulkhead 102 carry out inside and outside full weld and be connected, come as crossing the cabin pipe, the direct uncovered setting of one end that first pipeline 3 inserted indoor this moment, the blast pipe 101 of under-deck generator can stretch out the cabin from first pipeline 3.
Further, as shown in fig. 1 and 2, the first pipeline 3 has a first flange 31, the second pipeline 2 has a second flange 21 connected with the first flange 31, and the two pipelines are connected through the flanges to communicate with each other, wherein the exhaust pipe 101 sequentially extends into the cabin through the second pipeline 2 and the first pipeline 3 and is connected with the generator to provide an exhaust passage for the generator room. The exhaust pipe 101 may be fixedly connected to the second duct 2, and a radial gap exists between an outer wall of the exhaust pipe 101 disposed in the first duct 3 and an inner wall of the first duct 3, so that the exhaust pipe 101 passes through the first duct 3 without directly contacting the two, and thus heat of the exhaust pipe 101 is not directly transferred to the first duct 3, i.e., the bulkhead 102.
Specifically, the exhaust pipe 101 is fixedly connected to the exhaust pipe 101 in a fixed manner, and the exhaust pipe 101 is ensured to be not in contact with the pipe wall of the first pipe 3, a blank plate 5 can be arranged on the second pipe 2 away from the second flange 21, as shown in fig. 1 and 2, an opening through which the exhaust pipe 101 penetrates is formed in the blank plate 5, the opening can be arranged coaxially with the second pipe 2, one end of the exhaust pipe 101 firstly extends into the first pipe 3 during assembly, then the other end of the exhaust pipe 101 penetrates out of the opening of the blank plate 5 of the second pipe 2, the outer wall of the exhaust pipe 101 and the opening are connected through slow welding, at the moment, the outer wall of the exhaust pipe 101 is arranged in a suspended manner relative to the inner wall of the first pipe 3, and a radial gap exists.
In addition, an insulating gasket 6 may be disposed between the first flange 31 and the second flange 21, as shown in fig. 2, specifically, a plurality of fasteners such as bolts and nuts are uniformly disposed around the two flanges for connection (not shown in the figure), for convenience of assembly, the insulating gasket 6 may be firstly adhered to one of the flange surfaces, and then, after the two flanges are aligned, the fastening members sequentially penetrate through the first flange 31, the insulating gasket 6 and the second flange 21, so as to fixedly connect the three. Wherein, insulating pad 6 can select to be constituted by the red copper gasket that the parcel has graphite, and this insulating pad 6 has high temperature resistant, the little characteristics of coefficient of heat conductivity. Therefore, when the heat of the exhaust pipe 101 is transferred to the second pipeline 2, the heat transferred from the second pipeline 2 to the first pipeline 3 can be greatly reduced or completely blocked due to the arrangement of the insulating gasket 6 seen from the flange, so that the heat transferred to the bulkhead 102 is not enough to cause the deformation of the bulkhead 102 or the falling off of paint, thereby protecting the bulkhead 102 structure.
To further ensure that the heat of the exhaust pipe 101 disposed in the cabin and protecting the device part is not transferred to the cabin wall 102, in this embodiment, as shown in fig. 1-2, the outer wall of the exhaust pipe 101 disposed in the protecting device part may be wrapped with an insulating layer 4, and the purpose of the insulating layer 4 is to prevent the heat in the exhaust pipe 101 disposed in the protecting device part from being transferred to the whole protecting device through air, thereby achieving the dual functions of insulation and protection. The insulating layer 4 may be made of rock wool, slag wool, foam plastic, or the like.
Meanwhile, because the exhaust pipe 101 is subjected to high temperature for a long time, the exhaust pipe 101 needs to be replaced regularly, and in order to reduce the workload of replacing the exhaust pipe 101, in the embodiment, the exhaust pipe 101 and the muffler 103 are arranged separately, specifically, one end of the exhaust pipe 101 extending into the cabin is provided with the third flange 1011, and is in flange connection with the muffler 103 of the generator by using the third flange 1011, therefore, when the exhaust pipe 101 needs to be replaced, the fasteners of the third flange 1011, the first flange 31 and the second flange 21 can be directly loosened, so that the exhaust pipe 101 can be disassembled, the damage of the paint on the cabin wall 102 caused by cutting and welding the pipe for replacing the exhaust pipe 101 is prevented, a large amount of paint repair is required afterwards, the workload of replacing the exhaust pipe 101 is greatly reduced, and a large amount of time is saved for site construction.
Further, the third flange 1011 has an outer diameter 2mm to 5mm smaller than the inner diameter of the first pipe 3, and L in FIG. 2 is 2mm to 5 mm. The exhaust pipe 101 with the third flange 1011 conveniently penetrates through the first pipeline 3, meanwhile, when the insulating layer 4 wraps the outer wall of the exhaust pipe 101, two ends of the insulating layer 4 abut against the blank plate 5 and the third flange 1011 respectively, the edge of the insulating layer 4 in the thickness direction is flush with the outer diameter of the third flange 1011, and the insulating layer 4 can be fixed on the outer wall of the exhaust pipe 101 in a sticking mode. In addition, a layer of tinplate can be wrapped outside the insulating layer 4, so that the insulating layer 4 is protected from being damaged and corroded by external impurities.
In addition, the material of the second pipeline 2 can be seamless steel pipe or welded steel pipe, and the second pipeline is made into a finished pipe form.
In another embodiment, the pipe diameter of the second pipe 2 is smaller than that of the first pipe 3, so that a radial drop exists between the second pipe 2 and the first pipe 3, accordingly, the outer diameter of the exhaust pipe 101 needs to be smaller than or equal to the pipe diameter of the second pipe 2, and the second pipe 2 and the exhaust pipe 101 are in clearance fit. After the exhaust pipe 101 penetrates from the first pipeline 3 to the second pipeline 2, due to the existence of the radial drop, the outer wall of the exhaust pipe 101 is in a suspended arrangement relative to the inner wall of the first pipeline 3, a radial gap exists, the exhaust pipe and the first pipeline are ensured not to be in direct contact, and a welding process is omitted.
With reference to fig. 1 and 2, the following describes the assembly process of the exhaust pipe protection device:
installation: in the pre-outfitting stage, the side of the first pipeline 3 far away from the first flange 31 is inserted into a through hole reserved on the bulkhead 102, and the outer wall of the first pipeline 3 and the bulkhead 102 are fully welded.
