Description
Technical field
This utility model belongs to steam turbine cleaning equipment, particularly relates to the turbine blade fouling rinser being applied to middle-size and small-size generating, industrial turbine unit.
Background technology
The steam of medium and small gas turbine machine is essentially from small-sized industrial boiler, it is overheated that waste heat boiler or gasification burner produce, saturated vapor, due to small-sized industrial boiler, feedwater is required not strict by waste heat boiler or gasification burner itself, during it runs, blowdown control aspect is also lack of standardization, the steam quality causing its generation is bad, in steam, saliferous (alkali) amount is higher, these salt (alkali) part brings Turbine Flow Path into steam, and precipitate out along with the reduction of steam pressure in steam turbine, it is deposited on steam turbine flow passage component, form turbine blade fouling, steam turbine flow area is made to reduce, throttle flow reduces, power drop, efficiency reduces.Usual employing at present is taken off cylinder secondary and steam turbine rotor vane and dividing plate is carried out, and removes turbine blade fouling.Its existence has the drawback that steam turbine is taken off cylinder and cleaned, and work under bad environment, the repair time is long, and labor intensity is big, inefficiency；Frequently taking off cylinder and easily cause cylinder junction surface deformation and device damage, spare parts consumption is big, increases production cost；Additionally take off and cylinder process easily occurs there is potential safety hazard by personal injury accident.
Utility model content
For the defect overcoming prior art to exist, the purpose of this utility model is to provide a kind of turbine blade fouling rinser, avoid frequently taking off the manpower and materials waste that cylinder causes, reduce and take off the damage that turbine body is caused by cylinder, shorten the repair time, improve work efficiency, eliminate safe hidden trouble, reduce production cost.
Turbine blade fouling rinser, including steam turbine, steam turbine is sequentially connected with condenser by pipeline, condenses pump, controls valve A and condensate system, it is characterized in setting circulation pipe on the pipeline controlled between valve A and condensation pump, described circulation pipe sets control valve B and clean cycle system, one end connects pipeline, and the timing steam gate that the other end stretches into steam turbine is indoor.Closing control valve A, the cleanout fluid of about 80～90 DEG C is filled in condenser hotwell, open control valve B, opening and condense pump, it is indoor that cleanout fluid is entered timing steam gate by circulation pipe, enters in steam turbine from regulating valve opening, open barring gear and carry out jiggering, fouling is started effect by cleanout fluid, so moves in circles, thus reaching to remove the fouling of blade surface.
Compared with prior art, advantage is novel, compact conformation, rationally；By the repair time originally at least needing three days, shorten to 6 hours, highly shortened the repair time, improve work efficiency；Turbine blade cleans need not take off cylinder, reduce maintenance labor intensity, it is to avoid the hammering of instrument and raw draw, the damage that spare part is caused such as firmly drag, and has ensured the intact of equipment performance, has reduced spare parts consumption, reduced production cost, has eliminated and take off the potential safety hazard that cylinder brings.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of turbine blade fouling rinser.
In figure: 1-steam turbine, 2-coagulator, 3-pipeline, 4-condensation pump, 5-control valve A, 6-condensate system, 7-control valve B, 8-circulation pipe, 9-clean cycle system.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in further detail.
In FIG, turbine blade fouling rinser, including steam turbine 1, steam turbine is sequentially connected with condenser 2 by pipeline 3, condenses pump 4, controls valve A5 and condensate system 6, the pipeline controlled between valve A and condensation pump sets circulation pipe 8, setting control valve B7 and clean cycle system 9 on described circulation pipe, one end connects pipeline, and the timing steam gate that the other end stretches into steam turbine is indoor.Closing control valve A, the cleanout fluid of about 80～90 DEG C is filled in condenser hotwell, open control valve B, opening and condense pump, it is indoor that cleanout fluid is entered timing steam gate by circulation pipe, enters in steam turbine from regulating valve opening, open barring gear and carry out jiggering, fouling is started effect by cleanout fluid, so moves in circles, thus reaching to remove the fouling of blade surface.
Turbine blade fouling cleaning step is specific as follows:
(1), steam turbine being carried out, first shut down and cool down, cylinder interior temperature drops to about 80～90 DEG C, and owing to center housing temperature is higher, if being cooled to room temperature, the cool time that is bound to is longer, and then extends the repair time.
(2) Steam Turhine Adjustment porthole top cover, is opened, remove timing steam gate flap, condenser hotwell is filled the cleanout fluid of about 80～90 DEG C, cleanout fluid model is the MWC-01 of market sale, consider when the temperature of cleanout fluid and center housing temperature differ greatly, cylinder body cooling can be made too fast and produce stress, in subsequent use process, increase the unsafe factor of the cylinder body of steam turbine.It addition, the cleanout fluid of about 80～90 DEG C can accelerate the dissolving of fouling, shorten scavenging period.
(3), open steam turbine and condense pump, utilize the condensate system of steam turbine itself, cleanout fluid is delivered to Steam Turhine Adjustment porthole room, valve opening enters in steam turbine from regulating, pour into cleanout fluid successively from each valve opening, enter the cleanout fluid of steam turbine, flow through steam turbine high and low pressure blade successively, return to condenser from turbine discharge end again, keep bigger circulating load so to move in circles, turbine body flow passage component fouling is carried out.
(4), clean time, in order to ensure cleaning performance, must open barring gear carry out jiggering, constantly detect the concentration of cleanout fluid, additional clean liquid, clean 3～4 hours, open drain valve discharge.
(5), after fouling cleaning terminates, cleaning softening water need to be changed steam turbine inside is rinsed；And open all hydrophobic thorough drainings that carries out of steam turbine and proper extension warm-up period when starting.
Claims (1)
1. turbine blade fouling rinser, including steam turbine (1), steam turbine is sequentially connected with condenser (2) by pipeline (3), condenses pump (4), controls valve A (5) and condensate system (6), it is characterized in that setting circulation pipe (8) on the pipeline controlled between valve A and condensation pump, described circulation pipe sets control valve B (7) and clean cycle system (9), one end connects pipeline, and the timing steam gate that the other end stretches into steam turbine is indoor.
