Description
Technical field
The invention belongs to power station field of cooling, particularly a kind of V-type in triangular arranged is arranged vertically finned-tube bundle air cooling heat radiator.
Background technology
Indirect air cooling is a kind of Major Cooling Methods in air cooling power station, comprises air cooling heat radiator and air cooling tower two kinds of key equipments.Air cooling heat radiator has outside air cooling tower and is arranged vertically and horizontally disposed two kinds of forms in air cooling tower.Be arranged vertically air cooling heat radiator for outside air cooling tower, the vertically arranged finned-tube bundle generally v-shaped of two row forms a cooling unit, also known as cooling triangle.In air cooling tower bottom periphery space, rounded circumferentially arrangement forms whole air cooling heat radiator to cooling triangle.
In calm situation, cooling-air flows uniformly through the finned-tube bundle of each cooling triangle, enters air cooling tower, thus the recirculated water in cooling fins tube bank.Under the condition having ambient wind, just improve the cooling triangle flox condition of wind field upstream, cooling air delivery increases, and heat dispersion improves.But cool triangle in a large number for side, the finned-tube bundle that the surroundings wind field accelerating flowing makes cooling-air be difficult to flow through cooling triangle enters cooling tower, and cause cooling triangle heat dispersion sharply to decline, indirect air cooling system thermal performance reduces.Therefore for the power plant that average of the whole year wind speed is higher, the thermal performance of indirect air cooling system is subject to the remarkable of surroundings wind field and adverse effect.
In view of existing air cooling heat radiator cooling triangle is resisting the inherent shortcoming in environment strong wind in the outer circumferentially circular arrangement mode of tower, the V-type proposed in triangular arranged is arranged vertically finned-tube bundle air cooling heat radiator structure, by increasing windward side cooling triangle quantity, play and improve air cooling heat radiator flowing heat transfer characteristic, improve the object of indirect air cooling system thermal performance.
Summary of the invention
The object of the invention is to cool for the outer side that circumferentially circular arrangement mode causes of existing air cooling heat radiator cooling triangle tower the inherent shortcoming that triangle performance sharply declines in a large number, propose a kind of V-type in triangular arranged and be arranged vertically finned-tube bundle air cooling heat radiator, it is characterized in that, V-type is arranged vertically finned-tube bundle and forms cooling triangle, and this cooling triangle is made up of finned-tube bundle, tube bank supported on both sides post, shutter; Described cooling triangle, point three groups of continuous arrangements, each group forms a limit of equilateral triangle, and namely each organizes the subpoint of two row V-type finned-tube bundle intersecting lenses of each cooling triangle point-blank; Three groups of cooling triangles together constitute the V-type of tower outward in triangular arranged and are arranged vertically finned-tube bundle air cooling heat radiator.
The described finned-tube bundle forming cooling triangle adopts the steel pipe steel fin of biexhaust pipe, three combs, four combs, or adopts the version of aluminum pipe aluminum fin-stock of four combs, six combs.
Described steel pipe steel fin or aluminum pipe aluminum fin-stock version, its every two row finned-tube bundles are V-shaped to intersect, and two row finned-tube bundle open side are provided with steel structure supporting column, jointly form triangular cross-section skeleton, play the object of fixing finned-tube bundle with finned-tube bundle.
Described V-type is arranged vertically finned-tube bundle air cooling heat radiator, space layout is carried out perpendicular to the principle of power plant's location cardinal wind according to a limit of equilateral triangle, thus play increase windward side cooling triangle quantity, improve air cooling heat radiator flowing heat transfer characteristic, improve the object of indirect air cooling system thermal performance.
The invention has the beneficial effects as follows the triangular arranged being arranged vertically finned-tube bundle by V-type, resist the adverse effect of environment strong wind, improve the radiating effect of air cooling heat radiator, the design for indirect air cooling system provides a new technical thought.

Detailed description of the invention
The present invention proposes a kind of V-type in triangular arranged and is arranged vertically finned-tube bundle air cooling heat radiator, is explained below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the cooling triangle finned-tube bundle 3 of existing indirect air cooling system air cooling heat radiator 2 is arranged vertically on surrounding bottom air cooling tower 1, and rounded arrangement.In calm situation, each cooling triangle uniform air intake, air cooling heat radiator flowing heat transfer better performances.Under ambient wind effect, for just to the cooling triangle of ambient wind, ambient wind, through shutter 4, enters cooling triangle, then flows through V-type finned-tube bundle, enter air cooling tower, thus realizes and the exchange heat of finned tube beam tube Inner eycle water.Now ambient wind wind direction and inlet air direction basically identical.And for other most cooling triangle, ambient wind wind direction is inconsistent with cooling triangle inlet air direction, the two angle is β, and illustrate that ambient wind turns to through needing one after shutter, therefore there is loss coefficient, mobile performance is deteriorated, as shown in Figure 3.Especially for side cooling triangle, ambient wind is to almost vertical with cooling triangle inlet air direction, as shown in Figure 4, and along with flow area reduction, cooling triangle place, side ambient wind velocity increases, and ambient wind static pressure reduces, the driving pressure reduction of air flowing reduces, cooling-air is more difficult to enter cooling triangle, and therefore side cooling triangle performance sharply worsens, and air cooling heat radiator overall performance significantly reduces under ambient wind effect.
Fig. 5, Fig. 6 give indirect air cooling system air cooling heat radiator of the present invention and air cooling tower schematic diagram.The V-type finned-tube bundle air cooling heat radiator be arranged vertically within around air cooling tower is triangular arranged structure; Wherein V-type finned-tube bundle, tube bank supported on both sides post, shutter form cooling triangle, cooling three-legged structure identical with existing structure (as shown in Figure 2); Described cooling triangle, point three groups of continuous arrangements, each group forms a limit of equilateral triangle, and namely each organizes the subpoint of two row V-type finned-tube bundle intersecting lenses of each cooling triangle point-blank; Three groups of cooling triangles together constitute the V-type of tower outward in triangular arranged and are arranged vertically finned-tube bundle air cooling heat radiator; Cause adverse effect for reducing ambient wind as far as possible to indirect air cooling system operation, the cooling triangle of air cooling heat radiator 2 is triangular arranged surrounding bottom air cooling tower 1, and wherein a limit is towards power plant's location cardinal wind, namely vertical with cardinal wind.Now, ambient wind to cooling triangle inlet air direction completely the same, as shown in Figure 7.Ambient wind passes perpendicularly through shutter 4 and enters cooling triangular space, then flows through finned-tube bundle 3, enters cooling tower, thus decreases because of the inconsistent loss coefficient caused of ambient wind wind direction and cooling triangle inlet air direction.For the cooling triangle on equilateral triangle two other limit, when ambient wind flows through from the cooling triangle of windward side, flow area increases, ambient airflow prompt drop is low, the pressure causing two other limit place to cool triangle import increases, thus improve the driving pressure reduction of air flowing, the flowing heat transfer performance of air cooling heat radiator also can correspondingly be improved.
