Abstract
The utility model discloses the steam sealing cooler of a steam turbine, composed of the steam sealing cooler (3), an air suction blower fan (4), a pipe (2), etc. The steam sealing cooler (3) is communicated with the high voltage steam seal (5) of a steam turbine (1) through the pipe (2), and the steam sealing cooler (3) is provided with the air suction fan (4). The steam on the point of the high voltage steam seal (5) is discharged through the steaming cooler (3) under negative pressure function, which avoids the steam entering a condenser and avoids a shaft along the high voltage steam seal (5) sneaking in a bearing and mixing in turbine oil. Therefore, the steam sealing cooler of the steam turbine is characterized in that the steam sealing cooler of the steam is convenient for the regulation and control of the sealing system, reduces steam leak and energy loss and water content in the turbine oil, and increases the safe operation of the steam turbine (1), etc.
Description
One, affiliated technical field
The utility model is the packing cooling unit that a kind of steam turbine is used.
Two, background technique
At present, the sealing gland of steam turbine, because it is bigger influenced by main steam temperature, pressure, working medium etc., sealing system is regulated frequent, bad control; Leak vapour and enter vapour condenser, the degree of vacuum of vapour condenser is had certain influence.A large amount of evaporations are overflowed from the pipe of notifying, and cause the loss of big energy.Steam turbine in use often occurs that moisture content increases phenomenon in the turbine oil, and the main source of moisture content also is that evaporation seals in bearing from high press seal vapour along axle and sneaks into the oil, and the safe operation of unit has been caused great hidden danger.
Three, summary of the invention
The purpose of this utility model is can reduce the adjusting control of leaking water content in vapour energy loss and the turbine oil, being convenient to sealing system, the packing cooling unit of raising steam turbine safe operation for steam turbine provides a kind of.
The technological scheme that the utility model is taked is: at the utility model that a side setting of the high-pressure steam seal of steam turbine is communicated with high-pressure steam seal, the utility model is made up of packing cooler, the blower fan of bleeding, conduit etc.The packing cooler is a heat exchanger, and is connected with cooling water.The packing cooler is communicated with the high-pressure steam seal of steam turbine by conduit, on the packing cooler blower fan of bleeding is housed, and the drain opening of packing cooler is communicated with the flowing water case of steam turbine by pipeline.
Its working principle is: when the startup blower fan of bleeding, by the packing cooler, make in the high-pressure steam seal of steam turbine and produce negative pressure by the conduit place, the steam at high-pressure steam seal place under suction function through conduit, packing cooler, blower fan is discharged by bleeding, avoided the steam at high-pressure steam seal place to enter vapour condenser and seal in bearing and sneaked in the turbine oil, the moisture content in the turbine oil is increased, also be convenient to adjusting, the control of sealing system along the axle at high-pressure steam seal place.And steam enters in the packing cooler, owing to be connected with cooling water in the packing cooler, the moisture content in the steam condenses into water, and water of condensation is by the drain opening of packing cooler, through the drain tank of pipeline inflow steam turbine, the reuse of steam supply turbine.Steam has heated cooling water in the packing cooler simultaneously, but the cooling water after heating steam supply turbine again uses, the heat energy of the steam of high-pressure steam seal discharge is reused, therefore the utlity model has and be convenient to sealing system adjusting control, avoid steam moisture content to enter turbine oil, reduce the heat-energy losses of leaking vapour, improved the characteristics such as safe operation of steam turbine.
Four, description of drawings
Accompanying drawing is the utility model schematic representation.
Five, specific implementation method
Accompanying drawing is the utility model embodiment's a schematic representation.It is made up of conduit 2, packing cooler 3, the blower fan 4 of bleeding etc.Packing cooler 3 is for being connected with cooling water in heat exchanger, the packing cooler, and the water intake of cooling water is communicated with the water source, and the water outlet of cooling water is communicated with steam turbine 1, and the drain opening of packing cooler 3 lower ends is communicated with the drain tank of steam turbine 1.Packing cooler 3 is communicated with the high-pressure steam seal 5 of steam turbine 1 by conduit 2.The blower fan 4 of bleeding is housed on the packing cooler 3.
Start the blower fan 4 of bleeding, high-pressure steam seal 5 places at steam turbine produce negative pressure, steam herein is under suction function, enter packing cooler 3 through conduit 2, thereby prevented the gas leakage effectively, and eliminate because of the turbine oil water inlet problem that gland packing leakage caused, also made things convenient for adjusting, the control of sealing system simultaneously.Steam carries out heat exchange in packing cooler 3.Heated cooling water, steam supply turbine 1 uses.The water that steam condenses after cooling off in packing cooler 3 flow to the drain tank of steam turbine 1 by the drain opening of packing cooler 3 lower ends, and steam supply turbine 1 uses.
Therefore, the utlity model has and be convenient to sealing system adjusting control, avoid steam moisture content to enter turbine oil, reduce and leak the vapour heat-energy losses, improved the characteristics such as safe operation of steam turbine.
The packing cooler 3 of present embodiment is made up of casing, hydroecium 6, water-cooling tube 7 etc.Hydroecium 6 is located at the left and right sides of casing, and one of them hydroecium 6 is communicated with the water source, and another hydroecium 6 is communicated with steam turbine; Be provided with the water-cooling tube 7 that is communicated with this both sides hydroecium 6 between and arranged on left and right sides hydroecium 6, be provided with exhaust port in a side of casing, exhaust port is communicated with the blower fan 4 of bleeding; The upper end of casing is provided with inlet hole, and inlet hole is communicated with the high pressure sealing gland 5 of steam turbine 1 by conduit 2; The casing lower end is provided with drain opening, and drain opening is communicated with the drain tank of steam turbine 1.The steam of high-pressure steam seal enters casing through conduit 2 under suction function like this, by the water quench in casing both sides hydroecium 6 and the water-cooling tube 7, discharges to exhaust port again, and water of condensation then enters drain tank with the drain opening of casing lower end.
