Technical field
The utility model relates to a kind of Direct Air-cooled Unit air cooling island cooling device that uses on Direct Air-Cooled power plant hollow cool island.
Background technology
In the power plant of northern China, the radiating mode of condenser mainly adopts Direct Air-cooled Unit to dispel the heat, its structure mainly uses the square thereon A type radiating fin of a plurality of tactic fan contrapositions directly to dispel the heat, utilize circulation of air to take away the heat of water in the radiating fin, reduce the temperature of water.Heat abstractor is arranged on overhead general about 40 meters aerial usually, is provided with the windbreak about 10 meters on every side, is the air cooling island so be commonly called as.The air cooling island of this Direct Air-Cooled mode is in the heat radiation process; though good heat dissipation effect; simple in structure; easy to maintenance; be beneficial to and install and use; but also can be subjected to wind speed in the surrounding environment usually; wind direction; Temperature Influence; particularly during the broiling summer; ambient temperature reaches more than 30 °; radiator inlet wind-warm syndrome height; the air cooling tubes condenser radiating effect will variation; unit back pressure height; and after wind speed surpasses 5 meter per seconds or change of the wind; respective change also can take place in ambient air flow field, air cooling island, promptly produces the hot air reflux phenomenon around air cooling tubes condenser, causes radiator inlet heat to shed; wind-warm syndrome raises; the condenser radiating efficiency significantly reduces; fluctuation takes place or raises in the unit back pressure, thereby directly influences the unit operate as normal, causes unit output to be obstructed; be forced to load down; even the generation of shutdown phenomenon.How avoiding the generation of this situation, improve air cooling tubes condenser heat exchange design, reduce the influence to the air cooling tubes condenser radiating effect of radiator inlet wind-warm syndrome, particularly surrounding environment change, is the problem that the utility model need solve.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide and a kind ofly can effectively reduce the radiator inlet temperature, is subjected to ambient temperature, wind speed, Direct Air-cooled Unit air cooling island cooling device that the wind direction variable effect is little.
The utility model is achieved through the following technical solutions:
A kind of Direct Air-cooled Unit air cooling island cooling device comprises fan and A type radiating fin, and fan is positioned at the below of A type radiating fin, also comprises the air spray cooling device, and the air spray cooling device is located between fan and the A type radiating fin.
Described air spray cooling device comprises shower nozzle, electrically operated valve and water pump, shower nozzle between fan and A type radiating fin, in the shower nozzle spray orifice up, shower nozzle is linked in sequence by pipeline and electrically operated valve and water pump.
The quantity of described shower nozzle is more than one group, includes a plurality of minutes shower nozzles in every group of shower nozzle.
Filter and segmentation valve also have been linked in sequence between described every group of shower nozzle and the electrically operated valve.
A kind of Direct Air-cooled Unit air cooling island cooling device also comprises sweet-water tank, and sweet-water tank is connected with water pump with manually-operated gate by pipeline.Also comprise non-return valve, non-return valve is connected between segmentation valve and the electrically operated valve, also is provided with the return flow line between filter and sweet-water tank.
Direct Air-cooled Unit air cooling described in the utility model island cooling device, by above fan, settling the air spray cooling device, utilize the water smoke that sprays in the air spray cooling device that radiator porch air is cooled off, remedy environment temperature and increase the influence that air themperature is raise, avoided wind direction, after wind speed changes, the hot air reflux phenomenon that forms in the radiator porch, effectively controlled the rising of unit back pressure, thoroughly solved the influence of torridity summer to porch, Direct Air-cooled Unit air cooling island air themperature, have simple in structure, safeguard, easy to use, temperature reduction performance is stable, effectively guaranteeing to have reduced energy consumption in the process of the normal stable operation of unit, improve economic benefit, had market prospects extensively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, Direct Air-cooled Unit air cooling described in the utility model island cooling device, comprise fan 11, A type radiating fin 10 and air spray cooling device, fan 11 is positioned at the below of A type radiating fin 10, and the wind of fan 11 fan-outs is blown over from the bottom up by the slit on the A type radiating fin 10.The air spray cooling device comprises two groups of shower nozzles, two filters 7 and two segmentation valves 6, and non-return valve 5, electrically operated valve 4, water pump 3, manually-operated gate 2 and sweet-water tank 1, wherein include four branch shower nozzles 8 respectively in two groups of shower nozzles, four branch shower nozzles 8 lay respectively on the diverse location between fan 11 and the A type radiating fin 10, spray orifice up in the branch shower nozzle 8, every group of shower nozzle below is connected with filter 7 and segmentation valve 6 respectively, segmentation valve 6 by pipeline respectively with non-return valve 5, electrically operated valve 4, water pump 3, manually-operated gate 2 and sweet-water tank 1 order are communicated with, and also are connected with return flow line 9 between filter 7 and sweet-water tank 1.During use, water process manually-operated gate 2 through the desalination processing, water pump 3, electrically operated valve 4, non-return valve 5, behind segmentation valve 6 and the filter 7, most of water can flow back into the sweet-water tank 1 from return flow line 9, guarantee the height of sweet-water tank 1 middle water level and recycling once more of current, small part water then enters into branch shower nozzle 8 by each segmentation valve 6 and filter 7, and through upwards ejection of nozzle, make and between fan 11 and A type radiating fin 10, form a space that is full of water fog particle, because the wind of fan 11 blows from lower to upper, the air of process can adsorb a large amount of aqueous vapors, air themperature is descended, avoided because after the ambient temperature rising, the direct cooling effect instability of the air that brings, the shortcoming of cooling-down effect difference, also improved because wind speed, the variation of wind direction, the hot air reflux phenomenon that around A type radiating fin 10, forms that causes, simultaneously, water smoke also can be along with the motion of air, stick on the radiating fin 10, and along with heat on the radiating fin 10 is taken away in the volatilization of moisture once more, thereby reach the purpose that air and water smoke are united cooling, it is obvious to have a cooling-down effect, little advantage is affected by the external environment.Certainly, above-mentioned Direct Air-cooled Unit air cooling island cooling device can be provided with many group shower nozzles as required, with increase radiating efficiency and area of dissipation, and the quantity and the distributing position of the branch shower nozzle 8 between fan 11 and the A type radiating fin 10 also can be adjusted and be changed as required.
