Background
In the lubricating oil market, marine lubricating oil is a product type recognized as the highest technical threshold. Compared with land vehicles and the like which generally adopt fuels with higher cleanliness, the main engine of an ocean vessel generally uses residue type fuel oil, the sulfur content can reach 3.5 percent, and the base number is 5 to 10 times of that of the oil for land engines. Therefore, the marine lubricating oil has high requirements for acid neutralization ability and detergency of engine oil. Meanwhile, under the environment of humid marine climate and high salt content, the oil-water separation and rust prevention capability of the lubricating oil used on the ship are also greatly challenged.
Ocean-going vessel carriers travel to and from various airlines and ports around the globe for over 80% of international trade. The ocean voyage period of a large ship is long, and several weeks or even months are often needed for one sea trip. A large amount of lubricating oil is required and kept in reserve on the vessel. The marine lubricating oil is more expensive than the land-based lubricating oil because it is required to be high. Ocean vessel lubricating oils include many types of cylinder oils for ships, crankcase oils, diesel oils, and the like. Therefore, the lubricating oil for the long-distance voyage of the ship is very expensive, occupies large space and needs many safe preservation measures.
The normal running and mechanical wear of the lubricating oil for the ship along with the navigation of the ship lead the lubricating oil to be polluted and the quality to be reduced. Including metal debris, increased moisture, etc. during operation. Initial minor contamination can react with the lubricating oil, resulting in increased viscosity and ultimately in the need for replacement of the lubricating oil.
At present, simple mechanical filtration or centrifugal purifiers are mostly adopted for on-line purification of marine lubricating oil. The existing marine purifying device can remove large particles and pollution, such as particles larger than 3 microns or 5 microns, prolong the quality reduction time of some lubricating oil, but cannot thoroughly purify and recycle the polluted lubricating oil and cannot remove tiny pollutants, such as particles of 0.1-1 micron. Therefore, a system for filtering and recovering marine lubricating oil by fine filtration is needed.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide a lubricating oil filtration recovery system on line for boats and ships, install on boats and ships along with the navigation purifies retrieval and utilization lubricating oil immediately, its ultrafiltration system that utilizes the alloy milipore filter to constitute carries out recycle to lubricating oil to the use cost of enterprise has been reduced.
The purpose of the utility model is realized like this:
the utility model provides a marine lubricating oil filters recovery system on line, include the waste oil tank, prefiltration, the heater, middle oil tank one, ultrafiltration system, moisture absorber and recovery oil tank, the liquid outlet of waste oil tank communicates to the inlet of prefiltration, the liquid outlet of prefiltration communicates to the import of middle oil tank one through the heater, the export of this middle oil tank one communicates to the inlet of ultrafiltration system, and a liquid outlet of ultrafiltration system communicates to the inlet of middle oil tank one, another liquid outlet of ultrafiltration system communicates to the moisture absorber entry, the export of moisture absorber communicates to the recovery oil tank.
The utility model relates to a boats and ships are with lubricating oil on-line filtration recovery system, a heat preservation is equipped with to middle oil tank overcoat.
The utility model relates to a lubricating oil on-line filtration recovery system for boats and ships, filtration membrane in the ultrafiltration system is the alloy milipore filter.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses ultrafiltration system adopts the milipore filter especially alloy milipore filter, filters for current machinery, can filter more tiny granule, plays the purpose of complete filtration. Compared with the existing common ceramic membrane, the alloy ultrafiltration membrane is not easy to block because of the firmness and the thin membrane layer. Compared with the metal membrane on the market, the alloy ultrafiltration membrane has very small membrane pores, and is fine filtration instead of coarse filtration; and compared with polymer and plastic films, the alloy ultrafiltration membrane can stably operate at high temperature and high pressure.
How is the oxidized lubricant reduced throughout? How to neutralize the rising acid value?
