Fig. 1 is the schematic diagram of the first embodiment according to oil purification system of the present invention.As shown in Figure 1, this system comprises: multiple steam turbines 10, filtrating equipment 20 and absolute oil case 30.
Multiple steam turbines 10, wherein, multiple steam turbines 10 comprises the first steam turbine 11 and the second steam turbine 12, first steam turbine 11 and the second steam turbine 12 is dissimilar steam turbine, first steam turbine 11 has the first fuel reserve tank, and the second steam turbine 12 has the second fuel reserve tank.
Filtrating equipment 20, is connected to the first fuel reserve tank and the second fuel reserve tank respectively by petroleum pipeline, for filtering the lubricant oil in the first fuel reserve tank and the second fuel reserve tank.
Absolute oil case 30, is connected to the first fuel reserve tank and the second fuel reserve tank respectively by petroleum pipeline, and is connected with filtrating equipment 20 by petroleum pipeline, the clean lubricant oil obtained after filtering for stored filter device 20.
In this oil purification system, can comprise multiple steam turbines 10, multiple steam turbines 10 at least comprises two dissimilar steam turbine.Every platform steam turbine is at least equipped with a fuel reserve tank, and fuel reserve tank is for storing the lubricant oil needed for steam turbine work.Filtrating equipment 20 carries out filtration, purification for the lubricant oil in the fuel reserve tank to multiple steam turbines 10, and the clean lubricant oil obtained after filtration is stored in absolute oil case 30, and clean lubricant oil can enter the fuel reserve tank of steam turbine again, recycles.And for the non-clean lubricant oil that obtains after filtering, directly can enter other treatment device reclaims, or enter other production links and utilize.Such as, non-clean lubricant oil can enter purifying plant, carries out lubricant oil purification, so that the recycling of lubricant oil.Connected by petroleum pipeline between the fuel reserve tank of multiple steam turbines 10, filtrating equipment 20 and absolute oil case 30, petroleum pipeline is the conveyance conduit of lubricant oil.
Multiple steam turbines 10 can comprise two or more steam turbine of the same type, such as, and two steam extraction and condensing units, two waste heat filling generator set groups and two feed pump turbine groups.The steam turbine of three types can work simultaneously in this oil purification system, and 6 steam turbine share an absolute oil case 30, connect fuel reserve tank, filtrating equipment 20 and absolute oil case 30, realize the filtration, purification of lubricant oil by petroleum pipeline.Due in some mega projects, the steam turbine of number of different types may be needed to carry out operation simultaneously, therefore, can support that the steam turbine of number of different types, different position and height synchronously carries out lubrication oil filtration purification according to oil purification system of the present invention, need not manually switch back and forth, while increasing work efficiency, also meet the needs of steam turbine set safety, long-term operation.
Alternatively, a sump oil case can also be comprised according to oil purification system of the present invention.Lubricant oil in the fuel reserve tank of multiple steam turbines 10 is after filtrating equipment 20 filters, clean lubricant oil and non-clean lubricant oil can be obtained, clean lubricant oil enters in absolute oil case 30 by petroleum pipeline, and non-clean lubricant oil then can enter into sump oil case via petroleum pipeline.Non-clean lubricant oil carries out temporary transient storage in sump oil case, when memory space reaches certain value, can focus on whole non-clean lubricant oil.Multiple steam turbines 10 shares a sump oil case, can monitor the non-clean lubricant oil that multiple steam turbines 10 produces simultaneously, the fuel reserve tank of multiple steam turbines 10 is connected through petroleum pipeline with filtrating equipment 20 respectively, filtrating equipment 20 is connected with same sump oil case via petroleum pipeline again, petroleum pipeline layout is simple, uses more flexibly, is easy to operation.
The fuel reserve tank of multiple steam turbines 10 can be in identical position height, also can have height difference.Such as, oil purification system comprises two double extraction unit, two waste heat filling generator set and two feed pump turbines, two double extraction unit, two waste heat filling generating set oil tanks are arranged in 5.0m running layer, two feed pump turbine fuel tanks are arranged in 0.0m running layer, there is the obvious discrepancy in elevation and alternate position spike.The manufacturer of operation is carried out for some application steam turbine, in view of the restriction in plant area or space, cannot ensure that multiple steam turbines 10 operation is simultaneously to meet job requirements.The multiple steam turbines 10 that oil purification system support according to the present invention has diverse location height carries out lubrication oil filtration purification simultaneously.For multiple steam turbines 10 rational height is poor, the space of factory building can be saved on the one hand, make more reasonably layout, on the other hand, also can utilize the height difference between fuel reserve tank and filtrating equipment 20, absolute oil case 30, sump oil case, utilize Action of Gravity Field to a certain extent, realize the conveying of lubricant oil, the energy consumption produced when decreasing oil transfer pump conveying lubricant oil, more cost-saving, and environmental protection.It should be noted that, the height difference between dissimilar steam turbine can be arranged according to the job requirements of reality and objective environment, can be but be not limited only to as 5.0m.
This system can also comprise the first oil transfer pump.First oil transfer pump is connected with the second fuel reserve tank with the first fuel reserve tank respectively by petroleum pipeline, for cleaning lubricant oil from absolute oil case 30 to the first fuel reserve tank and the conveying of the second fuel reserve tank.The position of the first fuel reserve tank and the second fuel reserve tank can higher than, to be same as or lower than the position height of absolute oil case 30.When position height higher than absolute oil case 30 of the position of the first fuel reserve tank and the second fuel reserve tank, clean lubricant oil in absolute oil case 30 cannot overcome gravity and automatically flow in the first fuel reserve tank and the second fuel reserve tank, therefore needs use first oil transfer pump to provide power for the conveying of clean lubricant oil.Similarly, when the position of the first fuel reserve tank and the second fuel reserve tank is same as the position height of absolute oil case 30, clean lubricant oil in absolute oil case 30 cannot flow in the first fuel reserve tank and the second fuel reserve tank automatically, therefore, needs to carry out lubricant oil conveying by the first oil transfer pump.When position height lower than absolute oil case 30 of the position of the first fuel reserve tank and the second fuel reserve tank, the lubricant oil in absolute oil case 30 can rely on the effect of gravity, automatically flows in the first fuel reserve tank and the second fuel reserve tank, now, can not recycle the first oil transfer pump.It should be noted that; according in oil purification system of the present invention; as a kind of Alternate embodiments; first oil transfer pump is impel lubricant oil to overcome gravity is entered the first fuel reserve tank and the second fuel reserve tank power plant by absolute oil case 30, and other are any can ensure that lubricant oil overcomes gravity and enters the power plant of the first fuel reserve tank and the second fuel reserve tank all within protection scope of the present invention by absolute oil case 30.
Alternatively, lubricant oil when lubricant oil when absolute oil case 30 can also be used for storing the first overhaul of steam turbine in the first fuel reserve tank and/or the second overhaul of steam turbine in the second fuel reserve tank.General due to steam turbine fault, or in order to ensure that steam turbine set long-term safety operates, need to overhaul steam turbine set.When overhauling steam turbine set, often need the lubrication evacuation in steam turbine set fuel reserve tank, now, system needs the device temporarily holding the lubricant oil of discharging.According to oil purification system of the present invention, when the first/the second overhaul of steam turbine, absolute oil case 30 can play the effect of temporary reservoir set lubricant oil.Similarly, lubricant oil when lubricant oil when sump oil case can also be used for storing the first overhaul of steam turbine in the first fuel reserve tank and/or the second overhaul of steam turbine in the second fuel reserve tank.It should be noted that, when overhaul of steam turbine situation occurs, absolute oil case 30 and sump oil case also can divide the work to carry out lubricant oil storage, such as, absolute oil case 30 is for storing the lubricant oil in the first fuel reserve tank, sump oil case is for storing the lubricant oil in the second fuel reserve tank, or the capacity according to sump oil case and absolute oil case 30 is reasonably selected.
It should be noted that, generally, should ensure that multiple steam turbines 10 can not occur overhaul simultaneously.When multiple steam turbines 10 break down simultaneously need maintenance time, the capacity of absolute oil case 30 and sump oil case that should ensure is enough to hold all lubricant oil in multiple steam turbines 10 fuel reserve tank.
Alternatively, the first steam turbine is steam extraction and condensing machine, and the second steam turbine is feed pump turbine.Such as, oil purification system comprises two steam extraction and condensing units, and have the reconditioner of the collection dress mode of a set of routine, two steam extraction and condensing units share an absolute oil case 30 and a sump oil case.The available storage of water of sump oil case is not less than 120% of a whole oil mass of steam extraction and condensing unit, and the available storage of water of absolute oil case 30 is not less than 60% of a whole oil mass of steam extraction and condensing unit.Two units configure the oil transfer pump that 3 100% explosion-proof type Wechselstrommotors (IP55 grade, insulation F level) drive altogether, carry the lubricant oil in two steam turbine main fuel tanks and the lubricant oil in clean fuel tank respectively.By this system, the turned letter to fuel tank during single unit overhaul and filtration, purification can be realized.
Multiple steam turbines 10 can also comprise waste heat filling generator set, wherein, the fuel reserve tank of waste heat filling generator set is the 3rd fuel reserve tank, and the position height of the 3rd fuel reserve tank is identical with the position height of the first fuel reserve tank, and the position of the 3rd fuel reserve tank is higher than the position of the second fuel reserve tank.Such as, multiple steam turbines 10 comprises six steam turbine of three kinds of models, six steam turbine are arranged in factory building, two steam extraction and condensing units, two waste heat filling generator set group fuel tanks are arranged in 5.0m running layer, two feed pump turbine fuel tanks are arranged in 0.0m running layer, there is obvious height difference between steam turbine.Consider the needs of pipeline layout optimization, can be arranged apart by sump oil case, absolute oil case 30, and be arranged in 0.0m and operate layer correct position, reduce length of pipeline and resistance as far as possible.By by three kinds of dissimilar steam turbine and absolute oil case 30, sump oil case layout in different position height, optimize petroleum pipeline, can hall space be made full use of, utilize Action of Gravity Field to realize conveying and the purification of lubricant oil.
It should be noted that, the first fuel reserve tank, the second fuel reserve tank are identical with the lubricant type in the 3rd fuel reserve tank, and the capacity of the first fuel reserve tank is greater than the capacity of the second fuel reserve tank, and the capacity of the first fuel reserve tank is greater than the capacity of the 3rd fuel reserve tank.If the first fuel reserve tank, the second fuel reserve tank are different with the lubricant type in the 3rd fuel reserve tank, then share an absolute oil case 30 and sump oil case and can cause mutual pollution between oil product.Therefore, the first fuel reserve tank, the second fuel reserve tank precondition of being this oil purification system sharing an absolute oil case 30 and a sump oil case identical with the lubricant type in the 3rd fuel reserve tank.The capacity of the first fuel reserve tank is maximum, namely the fuel reserve tank capacity of steam extraction and condensing machine is maximum, there is overhaul when should ensure difference in the first fuel reserve tank, the second fuel reserve tank and the 3rd fuel reserve tank, this is also the public absolute oil case 30 of steam turbine of three kinds of different models and the precondition of a sump oil case as far as possible.
Alternatively, the position height of absolute oil case 30 is identical with the position height of the second fuel reserve tank, and the position height of sump oil case is identical with the position height of the second fuel reserve tank.Absolute oil case 30, sump oil case are identical with the position height of the second fuel reserve tank (fuel reserve tank of feed pump turbine), are the considerations based on factory building layout.Filter the clean lubricant oil obtained to be stored in absolute oil case 30, utilize the first oil transfer pump the clean lubricant oil in absolute oil case 30 can be flowed to the second fuel reserve tank.
This oil purification system can also comprise the second oil transfer pump, and the second oil transfer pump is connected with filtrating equipment 20 with feed pump turbine respectively by petroleum pipeline, for the lubricant oil in the second fuel reserve tank is flowed to filtrating equipment 20.Because feed pump turbine and filtrating equipment 20 are positioned at identical height, therefore, automatically cannot realize the conveying of lubricant oil therebetween, need the power that conveying lubricant oil is provided by the second oil transfer pump, to overcome the effect of gravity.It should be noted that, other are any can ensure that lubricant oil overcomes gravity is entered filtrating equipment 20 equipment by the second fuel reserve tank, all within protection scope of the present invention.
This oil purification system can also comprise portable oil filter, for filtering the lubricant oil in the first fuel reserve tank, the second fuel reserve tank or the 3rd fuel reserve tank; And oil strain interface, be connected with the first fuel reserve tank, the second fuel reserve tank or the 3rd fuel reserve tank respectively, and be connected with portable oil filter, for connecting portable oil filter with the first fuel reserve tank, for being connected portable oil filter with the second fuel reserve tank or for being connected portable oil filter and the 3rd fuel reserve tank.Petroleum pipeline reserves the interface of portable oil filter, and what can realize with the filtrating equipment 20 in oil purification system is standby mutually.When the filtrating equipment 20 in oil purification system breaks down, or when being optimized filtrating equipment 20 or overhauling, in order to not affect normal operation, portable oil filter can be temporarily utilized to carry out the purification of lubricant oil.The oil strain interface that this oil purification system is reserved, for the system failure provides measure for subsequent use.
