Description
Technical Field
The utility model relates to a boats and ships turbine field, a boats and ships fuel tank economizer system specifically says so.
Background
At the present stage, the fuel on the marine ship, particularly a large-scale ship, is pumped from a fuel storage cabin to a fuel precipitation cabin through a lightering pump, is pumped from the fuel precipitation cabin to a daily oil cabin and then flows from the daily oil cabin to a main auxiliary engine through a filter, the fuel needs to be heated to 40 ℃ to ensure normal fluidity, and because the fuel storage cabin has large oil storage, a large amount of steam needs to be used for preheating the fuel storage cabin, so the running cost of the ship is greatly increased; in addition, the fuel preheated in the fuel precipitation tank needs to be heated to more than 90 ℃ at the subsequent oil separation operation temperature, so that the subsequent oil separation machine can supply the daily oil tank conveniently, but the fuel deposited at the bottom of the fuel precipitation tank is easy to cause heat loss due to long-term precipitation, and the energy is wasted.
Disclosure of Invention
To the problem of heat energy cost between above-mentioned fuel storage cabin and the precipitation cabin, the utility model provides a simple structure can effectively reduce the energy consumption, avoids heat energy waste, reduces use cost's boats and ships fuel oil cabin economizer system.
The utility model adopts the technical proposal that: the ship fuel tank energy-saving system is characterized in that: the fuel oil storage cabin is respectively connected with two fuel oil precipitation cabins through oil supply pipelines with the storage cabin conveying valve, the fuel oil conveying pump and the conveying one-way stop valve, the bottoms of the two fuel oil precipitation cabins are respectively connected with the two cabin bottom one-way stop valves, the two cabin bottom one-way stop valves are connected with the preheating pipeline after being connected in parallel, the preheating pipeline is connected with the conveying pipeline between the storage cabin conveying valve and the fuel oil conveying pump, the preheating pipeline is connected with two parallel fuel oil preheating pumps in series, and the two parallel fuel oil preheating pumps are respectively connected with the two preheating one-way stop valves after being connected in parallel.
And a delivery pump oil inlet valve is arranged between a pipeline contact point between the two preheating one-way stop valves and the fuel delivery pump which are connected with the delivery valve of the storage cabin and the fuel delivery pump.
The filter is arranged behind the two cabin bottom one-way stop valves on the preheating pipeline.
When the temperature of fuel deposited at the bottom of the fuel depositing cabin is high, the one-way stop valve at the bottom of the cabin is opened, the fuel is filtered by a filter and then is sent to the fuel supply pipeline from the preheating one-way stop valve through the fuel preheating pump, the fuel inlet valve of the delivery pump is closed, the delivery valve of the storage cabin is opened, and the fuel is sent back to the fuel storage cabin, so that low-temperature fuel can be neutralized effectively, and the steam heating energy consumption of the fuel storage cabin is reduced; when oil is required to be supplied, the preheating one-way stop valve is closed, the oil inlet valve of the delivery pump, the fuel delivery pump and the delivery one-way stop valve are opened, fuel heated in the fuel storage cabin is supplied to the fuel precipitation cabin by the fuel delivery pump through the oil supply pipeline, the basic temperature of the fuel heated by the fuel delivered into the oil distributor from the fuel precipitation cabin is favorably improved, the energy loss caused by the cooling of high-temperature deposited fuel at the bottom of the fuel precipitation cabin is prevented, the integral preheating energy is saved, the energy consumption for heating the fuel of a ship is favorably reduced, and the running cost of the.
