Abstract

The utility model provides a steam turbine oil filtering system. The steam turbine oil filtering system comprises an oil filter which is connected with a main oil tank through two pipelines; one oil pipeline is provided with an oil filter inlet valve and the other oil pipeline is provided with an oil filter outlet valve; the pipeline with the oil filter inlet valve is connected with the bottom of the main oil tank; the pipeline with the oil filter outlet valve is connected with the upper part of the main oil tank; and one side, which is close to the oil filter, of the pipeline with the oil filter outlet valve is provided with an oil feeding pump. The steam turbine oil filtering system is technically characterized in that a secondary filtering box is arranged between the oil filter and the main oil tank and is divided into a sediment box and an oil storage box by a vertical separation plate; a backwashing pipeline and a pollution discharge pipeline of the oil filter are connected with the sediment box; the oil storage box is connected with the main oil tank through an oil discharge pipeline; the backwashing pipeline is provided with a backwashing valve and the pollution discharge pipeline is provided with a pollution discharge valve; and the oil discharge pipeline is provided with an oil discharge valve and an oil discharge pump. According to the steam turbine oil filtering system disclosed by the utility model, liquid from the backwashing pipeline and the pollution discharge pipeline of the oil filter enters the secondary filtering box to be subjected to secondary filtering and then flows into the main oil tank, thereby guaranteeing the quality of oil.

Description

A kind of steam turbine grease filtration system
Technical field
The utility model relates to the grease filter, is specifically related to a kind of steam turbine grease filtration system.
Background technology
My steam turbine in thermal power plant oil mixed with water problem is very serious, be head it off, through investigation in large quantities with to the analysis of existing oil filter oil strain form, existing production characteristics in conjunction with my company, we have chosen CDLJ magnetoelectricity type oil filter, can meet the needs of production by using, but also there is a great defective in it, be exactly when blowdown, water and the impurity of discharging contain a large amount of steam turbine oils, caused great waste, and the well cuts of back flush discharge are got back to again in the inlet box, both influence the quality of inlet box oil strain, caused economic loss again.
The utility model content
The purpose of this utility model provides a kind of steam turbine grease filtration system, its structural design advantages of simple, easy to use, time saving and energy saving, the oil-water mixture that inlet box can be emitted filters again, and the grease of inciting somebody to action wherein returns in the main fuel tank, fluid in the backwash tube is filtered again, filter out impurity wherein, thereby save production cost.
The purpose of this utility model realizes in the following manner: this steam turbine grease filtration system, comprise oil filter, described oil filter links to each other with main fuel tank by two pipelines, wherein a pipeline is provided with the oil filter inlet valve, another pipeline is provided with the oil filter outlet valve, the pipeline at oil filter inlet valve place links to each other with the bottom of main fuel tank, the pipeline at oil filter outlet valve place links to each other with the top of main fuel tank, oil filter outlet valve place pipeline is provided with oil-feed pump near oil filter one side, the technical scheme that adopts is: also be provided with the secondary filter case between oil filter and the main fuel tank, described secondary filter case is divided into settling tank and fuel reserve tank by vertical dividing plate, the counter-flushing pipeline of oil filter links to each other with settling tank with blowoff line, fuel reserve tank links to each other with main fuel tank by the oil extraction pipeline, counter-flushing pipeline is provided with back flush valves, described blowoff line is provided with sewage draining valve, and the oil extraction pipeline is provided with oil extraction valve and oil drain pump.
Preferably, described fuel reserve tank is provided with screen pack near upper horizontal.
Preferably, described settling tank is provided with the settling tank sewage draining valve.
Preferably, described screen pack is at least 2 layers, and the upper strata is that coarse filtration, lower floor are fine filtering.
Preferably, described oil extraction valve is near the oil drain pump inlet valve of fuel reserve tank setting and the oil drain pump outlet valve that arranges near main fuel tank.
Preferably, described oil drain pump outlet valve arranges near the upper end of main fuel tank.
The beneficial effects of the utility model are: this steam turbine grease filtration system, the oil water mixture that comes out from counter-flushing pipeline and the blowoff line of oil filter flows in the secondary filter case and flow into main fuel tank behind secondary filter, so just guarantee oily quality, saved the loss of steam turbine oil.
