Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ship manufacturing, and particularly relates to an anti-icing component for bilge water pipes in a TCS room of a ship. Background Art
[0002] Now more and more ships use LNG as ship liquid. Ships usually use an independent LNG fuel tank to store LNG fuel. All the pipes in and out of the LNG fuel tank are concentrated in one room, which is usually called TCS (TANKCONNECTION SPACE) room. The TCS room is an independent airtight cabin, which is usually located above or at the end of the LNG tank and connected to the LNG tank through a steel plate. The TCS room is forced to circulate with the air outside the ship through a fan. Usually, the temperature of the TCS room is slightly lower than the ambient temperature outside the ship by 5 degrees Celsius. Because there are many low-temperature pipes in the TCS room, and condensed water will form on the outside of these low-temperature pipes and gather at the bottom of the TCS room, the TCS room needs to be designed with bilge water pipes connected to the power pump to discharge the bilge water out of the cabin. LNG tanks usually store low-temperature liquefied natural gas (LNG) at -163℃, so the low temperature will be transmitted to the bulkhead of the TCS room along the steel plate of the LNG tank. The bilge water steel pipe usually penetrates the TCS bulkhead by welding the pipe to the bulkhead. In this way, the low temperature of the TCS bulkhead will also be transmitted to the bilge water steel pipe. After a long time, the temperature of the bilge water pipe will be lower than 0℃, causing the residual water in the pipe to freeze, thereby blocking the bilge water pipe and preventing the bilge water in the TCS room from being discharged.

[0003] In view of the above problems, the utility model provides an anti-icing component for bilge water pipes in a TCS room of a ship.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Furthermore, the component also includes an insulating bracket, which is arranged inside the TCS room. The insulating bracket includes a bracket, a jacket, an insulating pad and an insulating tinplate. The bracket is fixedly connected to the bulkhead of the TCS room. The bilge water pipe passes through the bracket from bottom to top. The insulating tinplate sleeve is arranged on the bilge water pipe, and its inner diameter is the same as the outer diameter of the bilge water pipe. The jacket is arranged on the outside of the insulating tinplate, and its inner diameter is the same as the outer diameter of the insulating tinplate. The surrounding side walls of the jacket are spaced apart from the inner side walls of the bracket.
[0007] Furthermore, the insulating bracket includes pipe clamp bolts and nuts, and the bracket includes an angle steel support rod and a U-shaped frame. Both ends of the angle steel support rod are vertically fixedly connected to the TCS room bulkhead, and the open end surface of the U-shaped frame is connected to the angle steel bracket through pipe clamp bolts and nuts.

[0011] The utility model discloses a ship TCS room bilge water pipe anti-icing assembly. First, the position where the bilge water pipe passes through the TCS bulkhead is arranged above the 0°C temperature field of the TCS cabin. The cabin penetration part is in the form of an insulating cabin penetration part. In this way, the bilge water pipe and the TCS bulkhead are separated by a low heat conductivity rubber material, so that the bilge water pipe does not directly contact the TCS bulkhead, and the pipe insulating cabin penetration part is completely exposed to the air. The temperature of the TCS bulkhead conducted in the insulating cabin penetration part will quickly diffuse into the air, so that the temperature of the bilge water pipe is consistent with the ambient temperature and is not affected by the low temperature of the tank body. At the same time, the bracket of the bilge water pipe in the TCS room is also in the form of an insulating bracket. The bilge water pipe in the TCS room is also not in contact with any low-temperature object of the TCS, so that the bilge water pipe is not affected by the low temperature, ensuring that the temperature of the bilge water pipe is above 0 degrees Celsius, preventing the bilge water pipe from freezing, and allowing the bilge water to be smoothly discharged from the TCS room through the pipeline.
