Meanwhile, the laminar tube flow heat transfer mode of the circulating cooling water of a traditional condenser is changed into an outside-pipe turbulent flow heat transfer mode, heat transfer can be greatly enhanced, and the vacuum degree of the condenser is guaranteed.
Description
Technical field
The utility model belongs to condensing heat transfer technology field, is specifically related to a kind of composite phase-change heat exchange type condenser of realizing that steam condenses rapidly.
Background technology
The performance quality of condenser has very important influence to generating efficiency, the gross coal consumption rate of power plant.The condenser of power plant's use at present, its condensation mechanism is recirculated cooling water and flows in heat exchanger tube, steam is emitted gasification latent heat outside heat exchanger tube, and the heat transferred recirculated cooling water, and recirculated cooling water is discharged into environment with heat and reaches the effect of condensing in cooling tower.
Traditional condenser because recirculated cooling water flowing velocity in pipe is slower, belongs to Laminar Flow, causes steam and recirculated cooling water heat exchange efficiency low, needs the effectively heat exchange of a large amount of heat exchange areas ability.Simultaneously, because recirculated cooling water is in the cooling tower heat exchange, cause containing in the water quality a large amount of dusts, therefore condenser copper tube usually adheres to the situation of foundry loam, fouling, causes the condenser heat transfer property to descend thus, and the end difference increases, vacuum reduces, thereby influence the operational efficiency of power plant unit, cause the generating set coal consumption to increase, station service power consumption rate increases.
Given this, if can effectively solve the influence of fouling and mud in the condenser, and significantly strengthen the heat transfer coefficient of cooling water cycle water side, for the economical operation of power plant very important meaning be arranged.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can guarantee the inner cleanliness factor of cooling tube bundle, can improve the novel condenser of the cooling circulating water coefficient of heat transfer again, thereby guarantee heat transfer intensity, reduce and clean, guarantee condenser vacuum, guarantee the economy of power plant operation.
