Description
Technical field
The present invention relates to a kind of steam turbine generator Seal Oil degassing drainage arrangement.
Background technology
The bipassage ring of large turbo-type generator double fluid ring sealing oil system becomes sky, hydrogen side oil ring respectively, has formed the sealing oil system loop of independently empty separately side and hydrogen side with corresponding empty lateral oil pump, differential valve and hydrogen side oil pump, balanced valve etc.
In the empty side oil circuit; From the oil of empty side fuel tank after empty lateral oil pump boosts; After the adjustment of the cooling of empty side oil cooler, strainer filtering, oily hydrogen differential valve, get into the empty side oil ring (with the oil pressure balance of sealing bearing bush hydrogen side oil ring) of generator sealed at both ends watt, the oil extraction side fuel tank that makes the return trip empty;
In the hydrogen side oil circuit; From the oil of hydrogen-side seal oil case after hydrogen side oil pump boosts; Behind the cooling of hydrogen side oil cooler, strainer filtering, balanced valve; Get into the hydrogen side oil ring (with the oil pressure balance of the empty side oil ring of sealing bearing bush) of generator sealed at both ends watt, hydrogen-side seal oil case (oil level of hydrogen-side seal oil case leans on the benefit draining valve to keep) is returned in oil extraction.
Relatively independent between sky, the hydrogen both sides oil circuit; Guaranteeing under the balanced valve sensitivity reliable premise; Empty hydrogen side two independent oil paths in the sealing bearing bush should not gone here and there or seldom string is oily; Can reduce oil that empty side contains impurity such as air, oil gas and moisture so as far as possible and directly contact, keep the quality of hydrogen with hydrogen in the generator.Empty hydrogen side oil circuit that we can say Seal Oil is relatively independent.
But; Normally in service at Turbo-generator Set double fluid ring sealing oil system; Because the empty hydrogen-side seal oil pressure reduction of balanced valve requires control certain limit (± 10mm water column), can complete equipilibrium, simultaneously because the difference and the precision difference of the sample position of fuel injection pressure signal; All can cause sky hydrogen-side seal oil string oil between the empty hydrogen side of sealing bearing bush oil ring inevitably; The size of string oil mass also has relation with the gap length of sealing bearing bush, the temperature of Seal Oil etc. simultaneously, and this will cause the carrying out of repairing of hydrogen-side seal oil case or oil extraction, more strengthen the string oil mass of empty hydrogen-side seal oil.
Owing to certainly exist the string oil of sky hydrogen-side seal oil; Impurity such as this air that will cause containing in the sky side seal oil, oil gas, moisture get in the hydrogen-side seal oil road; And with the process of contacted with hydrogen in discharge; Thereby cause hydrogen purity defective, this will threaten the safe operation of steam turbine generator; In order to keep the purity of generator hydrogen, need to strengthen dynamics and the frequency that hydrogen is mended in blowdown simultaneously, cause the waste of a large amount of hydrogen.
Summary of the invention
The object of the invention is exactly in order to address the above problem; A kind of steam turbine generator Seal Oil degassing drainage arrangement is provided, and the empty side seal oil that it will contain impurity such as air has just become the Seal Oil of clean cleaning after through degassing drainage arrangement, accomplishes the task of sealing generator hydrogen gas system once more jointly with hydrogen-side seal oil; Even string oil takes place or mends the phenomenon of oil extraction in empty hydrogen-side seal oil; The pollution problem of Seal Oil can not take place yet, thereby pollute hydrogen, reduce hydrogen purity.
To achieve these goals, the present invention adopts following technical scheme:
A kind of steam turbine generator Seal Oil degassing drainage arrangement, it comprises casing, and casing top is provided with oil inlet pipe, and the bottom is provided with flowline, on casing, also is provided with liquid level alarm, is provided with the ball float control device in the said casing and is connected with oil inlet pipe; In casing, also be provided with the industrial filler body, be provided with flow uniform board venthole on industrial filler body top, the bottom is provided with industrial filler body oil discharge passage; Casing top also is connected with vacuum lead.
Said vacuum lead is provided with oil mist separator.
Said ball float control device comprises a ball float, and ball float is connected with floater controlled valve on the oil inlet pipe.
Said casing is provided with observation window and/or inspection hatch.
The empty side seal oil that this device will contain impurity such as air has just become the Seal Oil of clean cleaning after through degassing drainage arrangement; Accomplish the task of sealing generator hydrogen gas system once more jointly with hydrogen-side seal oil; Even string oil takes place or mends the phenomenon of oil extraction in empty hydrogen-side seal oil; The pollution problem of Seal Oil can not take place yet, thereby pollute hydrogen, reduce hydrogen purity.The empty side seal oil of floater controlled valve flows to the flow uniform board; Evenly flow to the industrial filler body; When the Seal Oil of uniform temperature flows through the industrial filler body; Take slow membranaceous layer flow mode, sweep along under the effect of the impurity vacuum in casing in oil and separate fast, separate out, flow uniform board venthole constantly extraction under the effect of vacuum system of arranging through equilibrium.Oil inlet pipe is in a side of casing, and flowline is at bottom half, and observation window is installed in the front side of casing; The opposite side of casing has been installed vacuum lead and liquid level alarm, and vacuum lead is connected with oil mist separator, in the inside of casing; Floater controlled valve is connected with ball float, in the middle of the box house flow uniform board is arranged, and above the flow uniform board venthole is arranged; Be the industrial filler body below the flow uniform board, industrial filler body oil discharge passage arranged below the industrial filler body.The Seal Oil that gets into the industrial filler body is compiled the oil discharge passage outflow below side in its bottom, the back flows down along the device inwall.When oil level arrived a high position or low level in the device, said liquid level alarm sent the hi-lo signal alarm signal.Inspection hatch is arranged on the device top, and the ball float high and low position of floater controlled valve is suitably adjusted to satisfy liquid level requirement in the device.The vacuum system that connects steam turbine through said oil mist separator.Utilize low vacuum continuous rectification technology, separate the impurity that contains in the empty side seal oil.
Beneficial effect of the present invention:
1 get into the industrial filler body the oil discharge passage that compiles below side in its bottom of Seal Oil flow out, the back flows down along the device inwall, can not splash the Seal Oil liquid level after bottom of device purifies, and can avoid the Seal Oil generation oil gas that in device, splashes.
2 utilize low vacuum continuous rectification technology, can separate impurity such as the air that contains in the empty side seal oil, oil gas, moisture efficiently and effectively.
3 when oil level in the device arrives a high position or low level, and liquid level alarm sends the hi-lo signal alarm signal.
The top of 4 devices is provided with inspection hatch, can suitably adjust to satisfy liquid level requirement in the device the ball float high and low position of floater controlled valve.
5 devices through the height of the vacuum in the manually-operated gate control device, generally maintain low vacuum through the vacuum system of oil mist separator connection steam turbine, do not need to set up separately vavuum pump.
6 contain impurity such as air empty side seal oil just become the Seal Oil of clean cleaning after through degassing drainage arrangement; Accomplish the task of sealing generator hydrogen gas system once more jointly with hydrogen-side seal oil; Even string oil takes place or mends the phenomenon of oil extraction in empty hydrogen-side seal oil; The pollution problem of Seal Oil can not take place yet, thereby pollute hydrogen, reduce hydrogen purity.
