Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the present invention is described further:
Subregion air-valve counterflow cooling tower as shown in Figures 1 to 3, comprise tower body 1 and be located at the rain belt 2 in tower body 1 from the bottom to top, packing area 3, for spraying the water distribution system 4 of hot water and the air chamber 5 for mixing air, the tower body 1 that rain belt 2 sidepiece is corresponding has air intlet 11, tower body 1 corresponding above air chamber 5 is provided with exhaust apparatus 6, multiple water stream channel 7 is formed between water distribution system 4 and packing area 3, each water stream channel 7 is provided with the air-valve 9 for controlling this water stream channel 7 break-make away from one end of packing area 3, the gas channel 8 of mutual sealed separation is formed between adjacent water stream channel 7, this gas channel 8 and water stream channel 7 are communicated with rain belt 2 and air chamber 5 respectively.
Each air-valve 9 is corresponding with water distribution system 4, form water stream channel 7, gas channel 8 by seal isolation, current are allowed to pass from a passage, air passes from another passage, when water and air is each passed through respective passage, complete conduction heat exchange by the packing sheet of packing area 3, the heat of the hot water that water distribution system 4 sprays passes to air-flow, reduce water flow temperature, reach the object of cooling.Because the heat radiation of current is completed by indirect heat loss through conduction, belong to the dry calibration of 100%, do not have the increase of steam in air, after heating up, the water capacity of air does not change, and after being discharged cooling tower, does not just have white mist to produce; Simultaneously owing to there is no evaporative heat loss in current, thus achieve cooling tower water-saving result; And in order to take into account production task and energy-conservation, air-valve 9 can be opened, make air draught can direct contact heat water current, realize evaporative heat loss; More crucial, by controlling the opening and closing of each air-valve 9 respectively, then the evaporative heat loss that transmits of adjustable heat and heat loss through conduction ratio and mode, thus while realizing cooling tower water saving and fog dispersal, still can take into account production efficiency and energy-conservation.
Along with the rising of ambient temperature, when exhaust gas temperature is close to setting value, when cooling tower needs lower water temperature, by opening air-valve 9, or open the current of gas channel 8, the conversion progressively cooled to dry-and wet-type by dry calibration, progressively increases evaporative heat loss, while realizing cooling tower water saving and fog dispersal, take into account production task and energy-conservation.
For better the air distribution district that the packing area 3 in tower, water distribution system 4, air-flow pass being carried out subregion, to realize controlling more flexibly, packing area 3 is at least two filler subregions 31 by sealed separation, water distribution system 4 comprises multiple water-distributing device 41 be interconnected, filler subregion 31 and water-distributing device 41 one_to_one corresponding.Filler subregion 31 can be made up of multiple packing sheet, and water-distributing device 41 can be made up of pipeline and water-spraying fabric.
As a preferred embodiment of the present invention, the exhaust apparatus 6 of this example comprises air duct 61, motor 62, decelerator 63 and blower fan 64, the output shaft of motor 62 is connected with blower fan 64 by decelerator 63, and blower fan 64 is installed in air duct 61, and air duct 61 is installed on tower body 1 top.Gas in air chamber 5 leads through air duct 61 and is evacuated to outside tower body 1 by blower fan 64, to form convection current.
