Description
Technical field
The utility model belongs to condenser working service technical field, is specifically related to a kind of plant condenser ultrasonic antiscaling apparatus for eliminating sludge.
Background technology
Condenser is an important component part of Steam Turbine, and its effect is that the turbine discharge cooling is condensed into water, forms high vacuum, the steam that gets into steam turbine can be expand into far below atmospheric pressure do work more.The quality of condenser service behaviour is the security and the economy of the whole unit of influence directly.
Condenser vacuum is the leading indicator that characterizes the condenser operating characteristic, also is one of principal element that influences the Steam Turbine safety and economic operation.Influence the factor more complicated of condenser vacuum, comprise the characteristic of condenser heat-transfer character, condenser duty, copper pipe clean rate, coolant water temperature, cooling water inflow, cooling water system etc.For a condensing-type unit that draws gas that has put into operation; The film-cooled heat of condenser, cooling water inflow, condenser duty etc. are basic fixed; The characteristic of cooling water system, the type of cooling, coolant water temperature also receive the restriction of factors such as the geographical position, seasonal climate of power plant, change also difficulty relatively of above-mentioned factor through artificial mode.Comparatively speaking; Dirty and the fouling of condenser copper tube water side has more artificial room for improvement; Dirty and the fouling of condenser copper tube water side simultaneously also is the modal reason that causes condenser vacuum to worsen, and is the more economically viable approach that keeps the condenser high vacuum so improve and keep higher copper pipe clean rate.
At present domestic and international existing condenser descaling method mainly contain manual work disclose wash, modes such as glueballs cleaning, Cleaning by High Pressure Water Jet, Chemical cleaning, wherein the glueballs cleaning way is the most general.But these cleaning ways all exist shortcoming separately: manual work is disclosed to wash and can only be removed soft dirt and a spot of hard scale, removes not thoroughly, and labour intensity is big, needs to shut down, and can't reach gratifying effect.Glueballs clean to adopt the rubber ball system mode parallelly connected with circulation, need often come into operation, in case drop into untimelyly, form hard scale and just can not make the glueballs cleaning play effect, and system complex, ball collecting rate is low.Though it is the Cleaning by High Pressure Water Jet method can reach certain cleaning performance, very serious to the erosion of copper pipe.Water under high pressure is prone to cause the copper pipe distortion simultaneously, and to stopping up serious copper pipe DeGrain, adds this equipment manufacturing cost height, is easy to damage, and is difficult to defectives such as maintenance, has restricted the use of this method.Chemical cleaning generally all adopts the method for pickling, but Chemical cleaning need be shut down equally, chemical substance causes certain corrosion injury, operation cycle length, expense than higher to pipeline and equipment, simultaneously the chemical waste fluid contaminated environment.Therefore, develop a kind of plant condenser efficient, easy to operate, be the major issue that guarantees power plant safety, economical production to the harmless descaling and antiscaling method of equipment.
Summary of the invention
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of plant condenser ultrasonic antiscaling apparatus for eliminating sludge; It is to produce high frequency electric through supersonic generator; High frequency electric converts dither into through transducer, and horn acts in the condenser cooling water after dither is amplified, and causes forming in the liquid many small bubbles; The shock wave that utilizes collapse of bubbles to produce; Destroy the inner fastness of carbonization deposit, destroyed the bonding between carbonization deposit and the metal, reach the purpose of removing the dirt on the condenser copper tube inwall.
For solving the problems of the technologies described above, the technical scheme of the utility model is achieved in that
A kind of plant condenser ultrasonic antiscaling apparatus for eliminating sludge; Comprise condenser, wherein: the intake chamber end cap of described condenser is provided with horn, and the horn end cap is connected with the intake chamber end cap; The horn front end is arranged in the intake chamber; The horn rear end is connected with transducer, and transducer connects supersonic generator through first cable, and supersonic generator connects controller through second cable.
Further, described horn end cap is connected with the intake chamber end cap through bolt.
Further, described transducer is connected through screw with horn.
The beneficial effect of the utility model is:
1, the utility model is to produce high frequency electric through supersonic generator; High frequency electric converts dither into through transducer, and horn acts in the condenser cooling water after dither is amplified, and causes forming in the liquid many small bubbles; The shock wave that utilizes collapse of bubbles to produce; Destroy the inner fastness of carbonization deposit, destroyed the bonding between carbonization deposit and the metal, reach the purpose of removing the incrustation scale on the condenser copper tube inwall.
2, the utility model has been realized the online scale removal of plant condenser, antiscale, and condenser copper tube inwall dirt is thoroughly removed, and condenser heat exchange effect is significantly improved, and has practiced thrift cost of electricity-generating.Simultaneously, the design of remote time control, it is simple and convenient to have guaranteed that this kind plant condenser descaling method scene uses, and has reduced plant condenser scale removal, antiscale labour intensity.
