Abstract
The invention discloses a diversion device for environmental wind outside a vertically arranged air-cooled radiator of an indirect air cooling system, and belongs to the field of power station cooling systems. The diversion device for the environmental wind consists of six diversion flat plates which are uniformly distributed on the periphery of the windward side of the air-cooled radiator to form a fan shape, wherein the diversion flat plates have an equal height; the tops of the diversion flat plates are parallel to the upper edge of a cooling triangle of the air-cooled radiator; the widths of the diversion flat plates are sequentially gradually decreased from the far end to near end of a wind field; and the diversion flat plates keep a certain identical distance away from the inlet surface of the cooling triangle of the air-cooled radiator. By the diversion device for the environmental wind field outside the air-cooled radiator, after oncoming transversal wind which flows approximately in parallel from the air-cooled radiator is diverted by the diversion flat plates, the pressure of air at an inlet of the cooling triangle is increased, and the air enters the air-cooled radiator in a direction approximately vertical to the inlet surface of the cooling triangle, thereby making the cooling air flow of the cooling triangle in different sector more uniform and improving the radiation performance of the air-cooled radiator.
Description
Technical field
The invention belongs to the power station field of cooling.Be particularly related to a kind of indirect air cooling system and be arranged vertically type air cooling heat radiator external environment wind guiding device.Be to utilize the fan-shaped water conservancy diversion flat board that is arranged in the different size of air cooling heat radiator cooling triangle import specifically, carry out the guiding of air cooling heat radiator external environment wind field, thereby realize rationally utilizing the surroundings wind field energy, reduce the Air-cooled Unit back pressure, weaken the adverse effect of wind field, improve the indirect air cooling system runnability the air cooling heat radiator performance.
Background technology
The indirect air cooling mode has obtained fast development in China in recent years as one of power station methods for cooling.The air cooling heat radiator of indirect air cooling system has two kinds of arrangements, and a kind of being arranged horizontally in air cooling tower is another kind of for being arranged vertically in the peripheral circumferentially space of air cooling tower.Air cooling heat radiator is arranged vertically the integrated design that mode is convenient to realize interior desulfurizer of air cooling tower and chimney, has saved the power station land used, thereby becomes the preferential mode that adopts of indirect air cooling system gradually.
There are some researches show that under the ambient wind effect, the cooling air delivery of air cooling heat radiator windward side cooling triangle increases, heat-sinking capability strengthens, and lee face cooling triangle is because the inhibition in the interior zone, windward side of air cooling tower reduces flow, and heat radiation weakens.For cooling Delta Region, air cooling heat radiator both sides, outer circumferentially the flowing of the air cooling heat radiator that surroundings wind field causes makes that the air mass flow that enters radiator is lower, and heat-sinking capability is poorer.Air cooling heat radiator is under the surroundings wind field effect, and the flow of different sector cooling triangles becomes extremely inhomogeneous, and the whole cooling performance of air cooling heat radiator descends.
In view of the adverse effect of surroundings wind field to the indirect air cooling system heat dispersion, proposition is being arranged vertically facining the wind and the crosswind face of type air cooling heat radiator periphery, by the wind field guiding device is set, reach and rationally utilize the surroundings wind field energy, weaken its adverse effect, improve the purpose of indirect air cooling system runnability the air cooling heat radiator performance.
Summary of the invention
The objective of the invention is at the adverse effect of surroundings wind field the indirect air cooling system operation, propose a kind of indirect air cooling system and be arranged vertically type air cooling heat radiator external environment wind guiding device, it is characterized in that, the water conservancy diversion flat board that physical dimension does not wait is the fan-shaped periphery, windward side that is arranged in the outer air cooling heat radiator cooling of air cooling tower triangle, forms the surroundings wind field guiding device.
The water conservancy diversion flat board of described composition surroundings wind field guiding device is 6, and evenly distributes in the windward side of air cooling heat radiator cooling triangle, and its physical dimension is about the windward side center line left-right symmetry of air cooling heat radiator cooling triangle; The height of all water conservancy diversion flat boards equates that all its top is parallel with the upper limb of air cooling heat radiator cooling triangle, the rule design that the width of water conservancy diversion flat board successively decreases to proximal direction successively according to the far-end by wind field.
Angle between described each water conservancy diversion flat board that is fan-shaped even layout is all 36 °.
The rule that the width of described water conservancy diversion flat board successively decreases to proximal direction successively according to the far-end by wind field is the water conservancy diversion sheet width according to by the direction of surroundings wind field far-end to near-end, is that the rule of 0.5 Geometric Sequence is successively decreased with common ratio.
Described 6 water conservancy diversion are dull and stereotyped to cool off equating apart from d of triangle inlet face with air cooling heat radiator.
The invention has the beneficial effects as follows this air cooling heat radiator external environment wind field guiding device, by the water conservancy diversion flat board perpendicular to cooling triangle inletpiston upwards is set in ambient wind, the surroundings wind field that makes PARALLEL FLOW turns at the dull and stereotyped place of water conservancy diversion and enters air cooling heat radiator cooling triangle, can to a certain extent the kinetic energy of surroundings wind field be transformed into the pressure energy of air cooling heat radiator cooling triangle import, rationally utilize the surroundings wind field energy, it is low at the radiator both sides inlet pressure that the peripheral circumferential flow of air cooling heat radiator causes to overcome surroundings wind field, flow is little, the defective that air cooling heat radiator finned-tube bundle heating surface can not effectively utilize, thereby make the intake of air cooling heat radiator diverse location cooling triangle more even, the air cooling heat radiator performance improves.
