Description
Technical field
The invention belongs to the energy source and power technical field, island sunshade of particularly a kind of power station direct air-cooling and solar energy photovoltaic generator.
Background technology
In northern China, can near coal-mine power plant location water resource serious lack especially be difficult to bear big water consumption in dry season more, thereby have influence on the problem that build power plant.Direct Air-Cooling Technology; Because the water saving characteristics that it is outstanding; Can solve the bottleneck problem of water resource well, the used Direct Air-Cooled of this technology island comprises tens air cooling blower fans by column-row arrangement, utilizes surrounding air that direct air cooled condenser is carried out forced-convection heat transfer.Simultaneously; NORTHWEST CHINA local climate arid is partly cloudy, and the sunshine-duration is long, intensity of solar radiation is big, and solar energy is very abundant; Annual number at sunshine is 3000-3300 hour; Can carry out distributed photovoltaic power generation fully, " 12 " solar electrical energy generation installation target is increased to 21GW, and obviously distributed power generation will welcome bigger development space.Simultaneously, the Air-cooled Unit that put into operation the discovery that is in operation, the solar radiation meeting increases the parasitic thermal load of air cooling tubes condenser, increases the back pressure of air cooling tubes condenser, and the performance of Air-cooled Unit is produced harmful effect, and the unique method of head it off sprays exactly at present.Solar radiation is one of research air cooling technique problem demanding prompt solution to the influence on Direct Air-Cooled island.
Also there are not solar radiation defensive measure and the incorporate bibliographical information of air cooling island photovoltaic generation so far.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of structure rationally, is connected firmly, and regulative mode is flexible; The effect of blocking is played in solar radiation; Effectively reduce the solar energy that being radiated in the tube bank of air cooling island, and utilize solar energy to carry out photovoltaic generation, and do not influence air cooling island finned-tube bundle hot blast and effluent; Weaken the harmful effect of solar radiation greatly, improve the sunshade of power station direct air-cooling island and the solar energy photovoltaic generator of unit operation security and economy the direct air cooled condenser heat exchange.
The technical scheme that the present invention solves the problems of the technologies described above employing is: island sunshade of a kind of power station direct air-cooling and solar energy photovoltaic generator; It is provided with two-way vapor level distributing pipe, and vapor level distributing pipe below in every road is connected with " Λ " type finned-tube bundle, it is characterized in that: the sunshade blade that laterally is provided with some groups of finned-tube bundles between the said two-way vapor level distributing pipe; Each group sunshade blade is by a shore supports; Both sides are connected with the angular adjustment rope before and after the sunshade blade, and angular adjustment is restricted and all sunshade blades connected into the integral body of linkage, through pulling angular adjustment rope; Drive the sunshade blade and rotate, realize the continuous adjusting of sunshade blade angle around pillar; Said pillar lower end is welded on the finned-tube bundle support; On the said sunshade blade photovoltaic battery panel is installed.
Sunshade blade according to the invention is provided with support, and photovoltaic battery panel is equipped with on the support upper berth.
Angular adjustment rope according to the invention is steel wire rope, and it is fastened on each sunshade blade, and whole sunshade blades are linked together.
The width of sunshade blade according to the invention is between 40cm-200cm.The sheet spacing of said sunshade blade is 0.9 ~ 1.2 times of sunshade width of blade.
The present invention above the power station direct air-cooling unit finned-tube bundle, install sunshade and solar energy power generating integrated apparatus between the vapor level distributing pipe additional; It is arranged between finned-tube bundle top, air cooling unit, air cooling island two row steam-distributing pipes with certain inclination angle and mode parallel to each other, is venetian blind type sunshade and solar energy power generating integrated apparatus.Photovoltaic battery panel on the sunshade blade is over against the sun; The photovoltaic battery panel normal direction is parallel with sunray direct projection direction; Because Air-cooled Unit mostly is in NW China, latitude is between 30 °-51 °, and the angle of inclination is between 8 ° ~ 28 ° therefore and between the horizontal plane.The present invention to block the radiant energy from the sun, absorbs solar radiant energy according to the angle of inclination of the variation adjusting sunshade blade of sun direct projection angle simultaneously to greatest extent; Sun direct projection angle is big more; The angle of sunshade blade and horizontal plane is more little, and during no sunlight, the sunshade blade vertically is provided with.The invention has the advantages that, under the Air-cooled Unit normal operation,, block solar radiation fully, the radiation from the sun can not be delivered on the finned-tube bundle, play the effect that reduces the finned-tube bundle thermic load through changing the angle of sunshade blade; Utilize photovoltaic generating system to absorb solar energy simultaneously, produce electric energy, reach the purpose of energy-saving and emission-reduction; The sunshade blade that photovoltaic battery panel is installed is parallel to each other, leaves the space between the sunshade blade, therefore can not influence the hot-air that passes finned-tube bundle and flow, and can the heat radiation on air cooling island not had a negative impact.
