Description

Technical field:

[0001] The invention relates to the field of ship pollution cleaning, and in particular to a fuel tank pipeline blocking prevention system and a ship thereof. Background technology:

[0002] At present, most of the domestic civilian ship power fuel oil systems still use heavy fuel oil (HFO) as the main fuel. Due to its high viscosity and low fluidity, heavy fuel oil is very easy to cause blockage in the fuel oil discharge pipe. The current conventional design of the discharge pipe is to arrange double valves, that is, the first valve on the oil tank wall is a stop valve, and the second valve is a self-closing discharge valve (standard requirement). The discharge valve is then connected to a short short pipe to the discharge funnel, and finally discharged to the fuel oil discharge tank or oil residue tank. However, this method of discharge is not clean and is still prone to blockage.

[0003] There is an urgent need for a fuel tank pipeline anti-blocking system, which helps to solve the problem that the existing technology lacks a technical problem that can clean heavy oil residues. Summary of the invention:

[0004] In one embodiment, the present invention provides a fuel tank pipeline anti-clogging system, which uses an air compressor to back-blow the heavy oil residue to thoroughly clean the heavy oil residue, helping to solve the problem that the prior art lacks a technical method that can clean the heavy oil residue.

[0056] According to actual operations on board, ships that use heavy oil as power fuel will regularly discharge fuel tanks to drain water and residues in the tanks. However, the heavy oil used on board is a synthetic oil with high viscosity and low fluidity. It is often observed from the funnel during discharge that only a small amount of residue, or even no residue, is discharged. This indicates that the pipelines and valves are clogged. If blockage is found, the shipyard or shipowner will arrange personnel to spend a lot of time and energy on inspection and unblocking, which can easily cause oil leakage pollution and increase the workload of personnel on board, thereby increasing costs.

[0063] In this embodiment, a specific structure of a fuel tank pipeline anti-clogging system is provided. After the heavy oil residue in the heavy oil tank flows into the fuel oil clarification tank 1, it accumulates therein due to its viscosity.
