The making of filler
The problem that at first needs to solve is the material selection of cooling filler, and the material of selected filler need to satisfy following requirement: possess stronger shock resistance, still can work after the earthquake of the experience limit; Possesses higher cooling capacity; Possess preferably hydrophilicity, easily moistening and adhere to by water; Flowing resistance is little, material is easily processed; Light weight, corrosion-resistant; Constructability can keep in repair.
From satisfying the requirement of cooling capacity, enough large film-cooled heat need to be arranged; From reducing the difficulty of processing of packing sheet, need material thickness thinner so that processing; From the antidetonation angle, need material to possess enough intensity and thickness.Consider above factor, the present invention has selected that intensity is large, toughness is strong, hydrophily is better and the stalloy that is easy to process is made packing sheet.
Carry out the design of filler pattern according to the cooling task, the core of filler pattern design is to satisfy the requirement of cooling capacity, makes the contact surface area of water and air large, time of contact is longer.
In order to satisfy cooling requirement, the cooling filler after the processing need to have enough large specific surface, needs restriction wave height and the pitch of waves.In the present invention, utilize machining to make the stalloy filler of folding corrugated plating, its be provided with perpendicular to water film flow in the antidetonation cooling tower to the horizontal annular ripple, to fold corrugated plating positive and negative stacked, at the inner passage that forms water and air reverse flow of filler, significantly increased the heat exchange area of air and moisture film.Hot water is evenly distributed to filling surface after shower nozzle sprays, form the slow-flowing stream of film-form from top to bottom along the packing sheet surface, thereby has larger contact area and long time of contact.Cold air flows from bottom to top through the space between hollow body in the middle of the packing sheet and contacts with moisture film is reverse, absorbs the heat that hot water distributes.To install, connect in order to prevent from blocking and being connected, adopt straight ripple formula (water, vapour flow channels vertical with horizontal plane).
Below in conjunction with illustrated in figures 1 and 2, describe in the nuclear power station antidetonation cooling tower of the present invention the process of filler in detail:
1. adopt corrosion-resistant and preferably stalloy making of hydrophilicity thin-film packing material sheet 10;
