Abstract
The invention relates to a mechanical draft air cooling condenser which comprises tube bundles (1), draught fans (2) and a framework (3). The framework (3) is of a rectangle or similar to a rectangle, the draught fans (2) are arranged on the framework (3), a draught fan unit (4) is formed by each draught fan (2), the corresponding tube bundle (1) and the framework (3), the number of the draught fan units (4) is at least one, or more draught fan units (4) are combined, each draught fan unit is provided with a plurality of side faces, two or more than two V-shaped structures formed by the tube bundles are arranged on at least one side face of each draught fan unit (4), each V-shaped structure comprises two or more than two tube bundles (1), and the tube bundles (1) are arranged in a vertical mode. The mechanical draft air cooling condenser is low in investment cost, occupied area is small after the draught fan units are combined, and therefore the draught fan units are suitable for being applied to a large scale mechanical draft air cooling condenser. The mechanical draft air cooling condenser is simple in pipeline connection.
Description
Technical field
The present invention relates to a kind of mechanical draft air cooling condenser, main support the use with thermal power plant's steam turbine or other industry steam turbines, the low-pressure steam of discharging for condensing turbine or turbine.
Background technology
The effect of air cooling condenser is that the low-pressure steam of will discharge after the inner acting of steam turbine is condensed into water.Compare with traditional water cooling condenser, the air cooling condenser water-saving result is remarkable, and thermal power plant and empty branch trade had obtained using more and more widely at home in recent years.The version of at present common mechanical draft air cooling condenser is such: tube bank is horizontally disposed on tens meters even tens of meters high platforms with " roof " shape (or " A " shape), many rows " " combine abreast on the roof by tube bank, disposed axle flow fan below tube bank carries out forced-convection heat transfer by the blower fan air blast.Because platform is higher, equipment load, wind load and earthquake load are all very large, and its supporting construction departmental cost is higher.
Patent document CN100538241C discloses a kind of technical scheme of air cooling condenser, tube bank with the closed polygon arranged in form below blower fan, and formed the enclosure closely.This technical scheme is owing to having saved higher platform supporting construction, thereby reduced cost of investment, but, for the large air cooling condenser of heat exchange load, when a plurality of fan unit of needs, need to reserve certain airspace between each fan unit, after many Fans unit combination, floor space is large, and pipeline connects also trouble.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned mechanical draft air cooling condenser, provide that a kind of cost of investment is low, few, the pipeline of floor space connects simple mechanical draft air cooling condenser after many Fans unit combination.
The object of the present invention is achieved like this: a kind of mechanical draft air cooling condenser, comprise tube bank, blower fan and framework, framework is rectangle or approximate rectangular, and blower fan is arranged on framework, and every Fans, tube bank and the framework corresponding with it consist of a fan unit; Fan unit has one at least, perhaps combined by more fan unit, described fan unit has a plurality of sides, each fan unit two or more quantity of side arrangement at least therein by " V " shape structure of forming of tube bank, each " V " shape structure comprises the tube bank of two or greater number, and tube bank is arranged with vertical in form.
Mechanical draft air cooling condenser of the present invention, described " V " shape structure that is comprised of tube bank is arranged with form of straight lines.
Mechanical draft air cooling condenser of the present invention, described air cooling condenser only have a fan unit, in two side arrangement " V " shape structure of this fan unit.
Mechanical draft air cooling condenser of the present invention, described air cooling condenser has a plurality of fan units, two side arrangement " V " shape structure of each fan unit.
Mechanical draft air cooling condenser of the present invention, described air cooling condenser has a plurality of fan units, " V " shape structure that each fan unit only is comprised of tube bank a side arrangement.
The invention has the beneficial effects as follows:
1, save higher platform supporting construction, thereby reduced cost of investment.
2, large when condenser heat exchange amount, when needing a plurality of fan unit, the present invention can save floor space widely, therefore be more suitable for being applied to large specification mechanical draft air cooling condenser;
3, so that " " tube bank that shape is arranged in a straight line is more concentrated, and the connecting pipe of condenser inside and outside can be simpler, it is more convenient to arrange for V.

The specific embodiment
Embodiment 1:
Referring to Fig. 1 and Fig. 2, Fig. 1 is the layout schematic diagram (overlooking) of mechanical draft air cooling condenser embodiment 1 of the present invention.The side view of Fig. 2 embodiment of the present invention 1.Can be found out that by Fig. 1 and Fig. 2 mechanical draft air cooling condenser of the present invention is comprised of tube bank 1, blower fan 2, framework 3 and envelope wall 5.Framework 3 is rectangle or approximate rectangular, and blower fan 2 is arranged on framework 3.Blower fan 2, tube bank 1 and framework 3 consist of fan unit 4.Embodiment 1 only has a fan unit 4, " V " shape structure that is formed by tube bank in two side arrangement of this fan unit 4, each " V " shape structure comprises the tube bank 1 of two or greater number, and each side is arranged 4 " V " shape structures that are comprised of tube bank arranged in a straight line altogether.
With shown in Figure 2, during the work of mechanical draft air cooling condenser, the cross-ventilation that blower fan 2 produces air draught type makes cold air by restraining 1, and cold air carries out heat exchange with the steam of tube bank 1 inside, makes steam be condensed into water in tube bank 1.
Embodiment 2:
Referring to Fig. 3, what the present embodiment 2 represented is three fan unit 4 situations.In fact, embodiment 2 can see the combination of three embodiment 1 as.In actual applications, can the fan unit 4 of a plurality of (quantity is not only 3) this form be combined according to the load quantity of needs of heat exchange, form a mechanical draft air cooling condenser.
Embodiment 3:
Referring to Fig. 4, be that each fan unit 4 only has side arrangement tube bank 1 a, embodiment 3 to have 6 fan units 4, has represented the combining form of another kind of a plurality of fan unit 4 with embodiment 1 and embodiment 2 differences.When practical application, also the fan unit 4 of a plurality of (quantity is not only 6) this form can be combined, this point is similar to embodiment 2.
