Description
Technical field
The utility model relates to a kind of power station double-flow condenser.
Background technology
At present, the recirculated water water-in and water-out mode of the existing power station double-flow condenser that manufactures and designs of domestic condenser manufacturing firm all adopts advances side in being and goes out.It is close that turbine low pressure cylinder steam discharge quantity of steam in the condenser is dredged sidepiece in the middle of being, and common recirculated water water-in and water-out mode is advanced side in particularly and is gone out, the mode of this water-in and water-out, the cooling water pipe that circulating water temperature is low is positioned at the few zone of Steam Side of Condenser quantity of steam, and has had the cooling water pipe of certain temperature rise to be positioned at the many zones of turbine discharge amount through returning hydroecium.The temperature difference is larger, heat transfer coefficient is higher, the colder water of this mode Steam Side of Condenser section does not fully contact with a large amount of steam, and this regional cold is more than needed, and quantity of steam is not enough, its heat exchange efficiency is low, same sidepiece cold is not enough, and quantity of steam is more than needed, so that whole vapour side steam is inhomogeneous, local vapour locking is large, causes whole Steam Side of Condenser pressure bigger than normal.Unit capacity is larger, and this energy loss is larger, causes like this condenser heat exchanger effectiveness poor, and effective utilization rate of energy reduces.
The utility model content
The purpose of this utility model is to overcome the existing deficiency of Inlet and outlet water mode of condenser of the prior art, provides a kind of heat exchange efficiency high, and heat exchange is abundant, the obvious power station of energy-saving effect double-flow condenser.
The technical scheme of technical solution problem is: the power station double-flow condenser comprises cavity, be set up in parallel left hydroecium in the cavity front portion, left hydroecium, right hydroecium, right hydroecium, be set up in parallel left back hydroecium and right back hydroecium at the cavity rear portion, left hydroecium and left hydroecium heat exchanger tube and the left back hydroecium UNICOM by passing cavity, right hydroecium and right hydroecium heat exchanger tube and the right back hydroecium UNICOM by passing cavity, left water inlet and the left circulation water inlet pipe UNICOM of left hydroecium by being arranged on its downside, right water inlet and the right circulation water inlet pipe UNICOM of right hydroecium by being arranged on its downside, left hydroecium left delivery port and left recycling outlet UNICOM by side disposed thereon, right hydroecium right delivery port and right recycling outlet UNICOM by side disposed thereon.
The utility model is connected in the middle hydroecium of cavity with left recycling outlet and right recycling outlet, and left circulation water inlet pipe and right circulation water inlet pipe are connected in the hydroecium of cavity both sides, then the low-temperature circulating cooling water enters from the condenser sidepiece, flow out from the condenser middle part, colder water fully contacts with a large amount of steam, when the temperature difference is large, heat transfer coefficient is large, so that a large amount of steam carries out the high efficiency heat exchange, cold and quantity of steam are proportional, heat exchange is abundant, Steam Side of Condenser steam is even, and whole vapour locking is little, and condenser pressure obviously reduces, energy-saving effect is obvious, has improved the economy of condenser.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is left back hydroecium among Fig. 1 and the draw bail schematic diagram of right back hydroecium.
The specific embodiment
Now by reference to the accompanying drawings power station of the present utility model double-flow condenser is further specified, but be not limited only to following enforcement structure.
Referring to Fig. 1 and Fig. 2, Fig. 3, the power station double-flow condenser of the present embodiment is made of cavity 1, left hydroecium 2, left hydroecium 3, right hydroecium 4, right hydroecium 5, right recycling outlet 6, right circulation water inlet pipe 7, left circulation water inlet pipe 8, left recycling outlet 9, left back hydroecium 10, right back hydroecium 11 and heat exchanger tube 12 connections.
Be provided with four hydroeciums arranged side by side in cavity 1 front portion of condenser, be left hydroecium 2, left hydroecium 3, right hydroecium 4, right hydroecium 5, left hydroecium 2 and right hydroecium 5 are separately positioned on the both sides of cavity 1 front portion, and left hydroecium 3 and right hydroecium 4 are separately positioned on the centre of cavity 1 front portion; Hydroecium after the rear portion of cavity 1 arranges arranged side by side two, i.e. left back hydroecium 10 and right back hydroecium 11.The hydroecium of the front portion of cavity 1 and the hydroecium at rear portion are communicated with by the heat exchanger tube 12 that is arranged in the cavity, and specifically: left hydroecium 2 and left hydroecium 3 are by heat exchanger tube 12 and left back hydroecium 10 UNICOMs; Right hydroecium 5 and right hydroecium 4 are by heat exchanger tube 12 and right back hydroecium 11 UNICOMs.
