Technical Field
The utility model relates to an oil accumulation tank, specifically speaking are smoke exhaust fan oil accumulation tank belongs to oil accumulation tank field.
Background
The lubricating oil system of the steam turbine unit provides oil for lubricating a bearing of a steam turbine, sealing hydrogen in a sealing bush of a hydrogen-cooled generator set and related auxiliary security oil. The lubricating oil system is a relatively sealed system, the circulating power of the oil system is sourced from a pump set, and in order to ensure that oil can smoothly flow back to the oil tank after being used up, a smoke exhaust fan is additionally arranged on the upper part of the oil tank so as to ensure that micro negative pressure is generated in an oil return pipeline. However, when the steam seal of the steam turbine set is not adjusted by the steam inlet pressure, the steam seal close to the sealing tile of the generator leaks steam and enters the sealing lubricating oil in the sealing tile and returns to the oil tank along with the return oil, and the other function of the smoke exhaust fan is to exhaust the oil mist mixed in the lubricating oil system and exhaust the oil mist out of the atmosphere through the steam exhaust pipeline.
In the exhaust pipe, moisture is accumulated in the pipe due to the cooling of the pipe by air and the condensation of oil mist molecules, and a method for solving the problem is generally designed to arrange a U-shaped bend on the exhaust fan pipe, and lead a drain pipe out of the bottom of the U-shaped bend to be directly discharged into a trench. Because of the aquatic of condensing contains the greasy dirt in the exhaust fan pipeline, directly discharge the trench and can cause quality of water in the trench to further worsen, cause the increase of later stage water treatment cost, be not conform to current environmental protection health development theory.
Disclosure of Invention
In order to solve the problem, the utility model discloses a long-pending oil tank of smoke exhaust fan can be retrieved, deposit smoke exhaust fan pipeline condensate, carries out water oil separating, has reduced the water treatment cost, reduces water pollution.
The technical scheme of the utility model is that:
smoke exhaust fan oil accumulation tank, including oil accumulation tank barrel, the barrel adopts long and thin cylindrical tube structure to practice thrift area, the barrel top is equipped with the maintenance upper cover, makes things convenient for the barrel inspection to overhaul, the maintenance upper cover sets up the atmospheric pressure balance return bend, and its effect is inside and atmospheric pressure of balanced barrel, prevents that barrel internal pressure from increasing, causes the return water not smooth, the tube head of atmospheric pressure balance return bend prevents downwards to fall into debris such as dust, granule. The maintenance upper cover is provided with an oil accumulation tank inlet door which is communicated with a smoke exhaust fan, so that the oil accumulation tank can be conveniently isolated and maintained, and the smoke exhaust fan is arranged at the upper part of an oil tank of a lubricating oil system of the turboset; the lower part of the cylinder body is provided with a water drain valve, a ball valve convenient to operate is adopted, and the outlet end of the water drain valve is provided with a 90-degree elbow, so that the condensate can be conveniently recycled.
Further, the barrel sets up on the base, inside the base embedding civil engineering ground, make the barrel firm reliable.
Furthermore, the outlet of the elbow is provided with a sealing plug, so that the leakage problem caused by untight valve is thoroughly avoided.
Further, both ends are linked together with the level gauge about one side of barrel, conveniently look over the inside liquid level condition of barrel, and factor such as according to long-pending oily speed, barrel volume confirms, the level gauge is equipped with red, yellow, the green warning line of liquid level to remind daily maintainer in time to release the interior condensate water of barrel.
Furthermore, the upper end and the lower end of the liquid level meter are respectively provided with an upper stop gate and a lower stop gate, when the liquid level meter is abnormal, the liquid level meter is convenient to separate and overhaul, and the liquid level meter is provided with a liquid level transmitter and a buzzer.
The liquid level changer still with DCS system signal connection, the DCS system judges the liquid level signal, under the condition that the liquid level exceeds standard, sends the judged result to bee calling organ through the signal of telecommunication, and bee calling organ switch on sends audible and visual warning, can in time monitor the long-pending oil tank equipment state among the DCS system human-computer interface.
The steam seal and steam inlet pressure adjusting state of the steam turbine is indirectly reflected through recording the water level in the oil accumulation tank, if the steam inlet pressure is adjusted normally, the water level in the oil accumulation tank rises quickly, which indicates that the steam seal gap close to the sealing tile side is enlarged; if the steam seal gap is not changed, the steam seal inlet pressure is not adjusted properly, and the analysis of the state of the steam turbine equipment is facilitated.
The utility model discloses both considered on-the-spot practical application, solved the main part again and kept apart the maintenance problem, provide convenient condition for the overhaul of the equipments. The equipment leakproofness is good, and the multilayer protection thoroughly stops the emergence of running, falling, water clock phenomenon.
The utility model has the advantages that: the condensate water and the oil smoke mixture which are originally discharged into the trench are collected, the water and the oil are separated by utilizing the difference of the specific weight of the water and the oil, the condensate water is discharged into the trench through a water discharge pipeline, the oil is recycled and is uniformly treated in a special waste oil recycling barrel, the water treatment cost is reduced, and the water pollution is reduced.
The present invention will be further explained with reference to the drawings and examples.
